技术领域technical field
本发明涉及车辆技术领域，具体提供一种车辆以及用于车辆的后悬挂组件。The invention relates to the technical field of vehicles, and specifically provides a vehicle and a rear suspension assembly for the vehicle.
背景技术Background technique
目前，汽车行业内对于后车轮悬挂结构的设计有多种方案，常见的有非独立悬挂***和独立悬挂***，其中，独立悬挂***中的麦弗逊悬挂***因具有结构紧凑、车轮跳动时前轮定位参数变化小、操纵稳定性强等优点而多应用在中小型轿车上。At present, in the automotive industry, there are many schemes for the design of the rear wheel suspension structure. The common ones are non-independent suspension system and independent suspension system. Among them, the McPherson suspension system in the independent suspension system has a compact Because of the small change in wheel alignment parameters and strong handling stability, it is mostly used in small and medium-sized cars.
但是，麦弗逊悬挂***由于只依靠下托臂和减震器支柱来承受冲击力，导致车身稳定性较差，且减震器倾斜安装，导致汽车行驶在凹凸不平的路面时不可避免地会产生跳动，整车抗侧倾能力较差。However, because the MacPherson suspension system only relies on the lower support arm and the shock absorber strut to bear the impact force, the stability of the vehicle body is poor, and the shock absorber is installed obliquely, which inevitably causes the car to run on uneven roads. Jumping occurs, and the vehicle's anti-rolling ability is poor.
发明内容Contents of the invention
本发明旨在解决或至少缓解上述技术问题，即解决或缓解现有汽车的车身稳定性和抗侧倾能力较差的问题。The present invention aims at solving or at least alleviating the above-mentioned technical problems, that is, solving or alleviating the problems of poor body stability and anti-rolling ability of existing automobiles.
在第一方面，本发明提供了一种用于车辆的后悬挂组件，所述后悬挂组件包括：活动部，其配置于所述车辆的车轮；固定部，其设置于所述车辆的车架上；其中，所述活动部与所述固定部滑动连接，以便：借助于该滑动连接，所述车轮至少能够在竖直方向上相对所述固定部滑动。In a first aspect, the present invention provides a rear suspension assembly for a vehicle, the rear suspension assembly comprising: a movable portion configured on a wheel of the vehicle; a fixed portion disposed on a frame of the vehicle above; wherein, the movable part is slidably connected to the fixed part, so that: by virtue of the sliding connection, the wheel can at least slide relative to the fixed part in the vertical direction.
本发明提供的后悬挂组件，通过在车架上设置固定部，在车轮上设置活动部，使得车轮借助固定部与活动部之间的滑动连接至少实现沿竖 直方向上的滑动运动，这样一来，当车轮转向或遇到障碍物时，障碍物会向车轮至少施加纵向载荷，一些情形下还会施加横向载荷，纵向载荷转移至活动部后会转化为活动部的竖向滑动运动，横向载荷会被活动部与固定部构成的滑动副吸收消化，从而将车轮的跳动运动转化为车轮的竖向滑动运动，对于车身而言，其侧倾中心与质心不会发生偏离，因此车辆不会发生侧倾，从而始终保持车轮定位参数的恒定，提升车身稳定性和抗侧倾能力。The rear suspension assembly provided by the present invention is provided with a fixed part on the vehicle frame and a movable part on the wheel, so that the wheel at least realizes sliding movement along the vertical direction by means of the sliding connection between the fixed part and the movable part. Now, when the wheel turns or encounters an obstacle, the obstacle will apply at least a longitudinal load to the wheel, and in some cases a lateral load will also be applied. After the longitudinal load is transferred to the movable part, it will be converted into a vertical sliding motion of the movable part. The load will be absorbed and digested by the sliding pair formed by the movable part and the fixed part, thereby converting the beating motion of the wheel into the vertical sliding motion of the wheel. For the body, the roll center and the center of mass will not deviate, so the vehicle will not Rollover occurs, so that the wheel alignment parameters are always kept constant, and the stability of the vehicle body and the ability to resist rollover are improved.
本发明中，活动部与车轮的连接可以是固定连接，也可以是枢转连接，枢转连接时，转动中心线沿竖直方向延伸。举例而言，车轮固定连接有转向节，转向节可以与活动部固定连接，车轮的转向通过活动部自身具有的转动连接结构来实现。或者转向节可以与活动部枢转连接，转动中心线沿竖直方向延伸，车轮的转向通过转向节相对活动部的转动来实现。In the present invention, the connection between the movable part and the wheel may be a fixed connection or a pivotal connection. During the pivotal connection, the center line of rotation extends along the vertical direction. For example, the wheel is fixedly connected with a steering knuckle, and the steering knuckle may be fixedly connected with the movable part, and the steering of the wheel is realized through the rotating connection structure of the movable part itself. Or the steering knuckle may be pivotally connected with the movable part, the center line of rotation extends along the vertical direction, and the steering of the wheels is realized by the rotation of the steering knuckle relative to the movable part.
对于活动部与固定部之间的滑动连接，可以是活动部单纯地在竖直方向上沿固定部滑动，例如将固定部的至少一部分制成棱柱结构，活动部套设于该棱柱结构并仅在竖直方向上相对棱柱结构滑动。或者可以是竖向滑动与转动的组合运动，例如将固定部的至少一部分制成圆柱结构，活动部套设于该圆柱结构，则活动部相对固定部在竖直方向上滑动的同时还相对固定部转动，转动中心线即圆柱结构的轴线。For the sliding connection between the movable part and the fixed part, the movable part can simply slide along the fixed part in the vertical direction, for example, at least a part of the fixed part is made into a prism structure, and the movable part is sleeved on the prism structure and only Sliding relative to the prismatic structure in the vertical direction. Or it can be a combined movement of vertical sliding and rotation. For example, at least a part of the fixed part is made into a cylindrical structure, and the movable part is sleeved on the cylindrical structure, so that the movable part is relatively fixed while sliding in the vertical direction relative to the fixed part. The part rotates, and the centerline of the rotation is the axis of the cylindrical structure.
替代性地，活动部相对于固定部的转动运动还可以通过连接结构转移至活动部自身。具体而言，可以通过在活动部与固定部之间增加轴承来实现相对运动的转移。Alternatively, the rotational movement of the movable part relative to the fixed part can also be transferred to the movable part itself through the connecting structure. Specifically, the transfer of relative motion can be realized by adding a bearing between the movable part and the fixed part.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述固定部包括导向部分，所述活动部包括与所述导向部分适配的滑动部分，所述活动部借助于所述滑动部分与所述导向部分的滑动配合相对所述固定部滑动。Regarding the aforementioned rear suspension assembly for vehicles, in some embodiments, the fixed part includes a guide part, the movable part includes a sliding part adapted to the guide part, and the movable part The sliding fit of the part and the guide part slides relative to the fixed part.
通过设置导向部分和与导向部分适配的滑动部分，能够更好地引导活动部的滑动运动。By providing a guide part and a sliding part adapted to the guide part, the sliding movement of the movable part can be better guided.
导向部分的设置方式可以有多种。举例而言，导向部分可以为沿竖直方向延伸的导向槽结构，或者为沿竖直方向延伸的导向柱结构，或者 为导向槽结构与导向柱结构的组合等。此外，导向槽结构或导向柱结构在竖直方向上延伸的尺寸可以是任意的，只要保证其至少一部分能够用于引导滑动部分的滑动运动即可。There are many ways to set up the guide part. For example, the guide part can be a guide groove structure extending in the vertical direction, or a guide post structure extending in the vertical direction, or a combination of the guide groove structure and the guide post structure, etc. In addition, the dimension of the guide groove structure or the guide post structure extending in the vertical direction can be arbitrary, as long as at least a part thereof can be used to guide the sliding movement of the sliding part.
滑动部分的设置方式也有多种。举例而言，滑动部分可以是一体成型，或者可以是由多个单体组合而成，对于由多个单体组合的构造方式而言，单体的数量也可以有多种情形。There are also various ways of setting the sliding part. For example, the sliding part can be integrally formed, or can be formed by combining multiple monomers. For the construction mode of combining multiple monomers, the number of monomers can also have various situations.
可以理解的是，固定部还可以包含其他与导向部分的安装相关的功能构件。举例而言，导向部分通过连接部分固定连接至车架。此外，由于活动部还与转向节连接，与转向节可以固定连接或枢转连接，在此情形下，活动部还可以包括转动部分。It can be understood that the fixing part may also include other functional components related to the installation of the guide part. For example, the guide part is fixedly connected to the vehicle frame through the connecting part. In addition, since the movable part is also connected to the steering knuckle, it can be fixedly connected or pivotally connected to the steering knuckle. In this case, the movable part can also include a rotating part.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述滑动部分包括至少一个单体，所述至少一个单体形成或构造出所述滑动部分。Regarding the above-mentioned rear suspension assembly for a vehicle, in some embodiments, the sliding part includes at least one single body, and the at least one single body forms or configures the sliding part.
当滑动部分仅由一个单体构造形成时，由于单体结构的滑动部分不需要进行额外的连接操作，因而其自身的强度更高，还可以避免因连接失效导致的滑动失灵等种种问题。When the sliding part is formed of only one single structure, since the sliding part of the single structure does not require additional connection operations, its own strength is higher, and various problems such as sliding failure caused by connection failure can be avoided.
当滑动部分由多个单体构造形成时，可以使滑动部分与导向部分的连接更灵活，对导向部分的结构设计的限制会大大减小，方案更容易实现。When the sliding part is formed by multiple single structures, the connection between the sliding part and the guiding part can be made more flexible, the restriction on the structural design of the guiding part can be greatly reduced, and the solution can be realized more easily.
需要说明的是，当单体为多个的情形下，各个单体的结构可以相同，也可以不同或部分不同。此外，各个单体的功能可以相同，也可以不同或部分不同。It should be noted that, when there are multiple monomers, the structures of the respective monomers may be the same, different or partly different. In addition, the functions of the individual monomers may be the same, or different or partially different.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述单体包括多个的情形下，所述多个单体中的至少一部分固定连接或者一体成型。Regarding the above-mentioned rear suspension assembly for a vehicle, in some embodiments, when the unit includes a plurality of units, at least a part of the plurality of units is fixedly connected or integrally formed.
当单体为多个的情形下，各个单体之间的连接方式可以有多种。举例而言，单体包括第一单体和第二单体，第一单体和第二单体在扣合后通过紧固件固定连接，从而构造形成滑动部分。或者单体包括第一单体、第二单体和第三单体，在第一单体和第二单体处于扣合状态的情形下，第三单体夹设于第一单体和第二单体之间，从而在第一单体和第二单体之间形成间隙，构造形成的滑动部分相对于导向部分滑动的过程中，由 于滑动部分自身形成的间隙会减小与导向部分之间的接触面积，进而减小滑动过程中的摩擦阻力。其中，第三单体可以与第一单体或第二单体一体成型，也可以通过焊接、粘接、螺接等连接方式连接。When there are multiple monomers, there may be various ways of connecting the monomers. For example, the unit includes a first unit and a second unit, and the first unit and the second unit are fixedly connected by a fastener after fastening, so as to form a sliding part. Or the monomer includes a first monomer, a second monomer and a third monomer, and when the first monomer and the second monomer are in a buckled state, the third monomer is sandwiched between the first monomer and the second monomer. Between the two monomers, a gap is formed between the first monomer and the second monomer. During the sliding process of the sliding part formed by the structure relative to the guide part, the gap formed by the sliding part itself will reduce the gap between the guide part and the guide part. The contact area between them reduces the frictional resistance during the sliding process. Wherein, the third unit can be integrally formed with the first unit or the second unit, or can be connected by welding, bonding, screwing and other connection methods.
可以理解的是，还可以是其他能够构造形成滑动部分的单体构造方式。It can be understood that other single-body construction methods capable of forming the sliding part are also possible.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述滑动部分包括第一单体和第二单体，所述第一单体和所述第二单体以彼此扣合的方式构造出与所述导向部分匹配的结构。Regarding the above-mentioned rear suspension assembly for a vehicle, in some embodiments, the sliding part includes a first unit and a second unit, and the first unit and the second unit are fastened to each other. way to construct a structure that matches the guide portion.
这样，提供了滑动部分的一种具体构造方式。通过将第一单体和第二单体以彼此扣合的方式构造形成与导向部分匹配的结构，可以使滑动部分更方便地连接至导向部分，且此种形式的滑动部分的结构更简单易实现。In this way, a specific configuration of the sliding portion is provided. The sliding part can be more conveniently connected to the guiding part by constructing the first unit and the second unit in a buckling manner to form a matching structure with the guiding part, and the structure of the sliding part in this form is simpler and easier accomplish.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述导向部分包括导向主体，所述导向主体上设置有滑动区段，所述滑动部分与所述滑动区段滑动配合。Regarding the aforementioned rear suspension assembly for a vehicle, in some embodiments, the guide part includes a guide body, the guide body is provided with a sliding section, and the sliding part is slidingly engaged with the sliding section.
这样，提供了导向部分的一种构造方式。可以理解的是，导向部分除导向主体之外，还可以包括辅助导向部分，辅助导向部分用于配合导向主体实现导向功能。举例而言，导向主体为导向柱结构，辅助导向部分为导向槽结构，即导向部分为导向柱与导向槽的组合，其中导向柱起主要作用。In this way, a configuration of the guide portion is provided. It can be understood that, in addition to the guiding body, the guiding part may also include an auxiliary guiding part, and the auxiliary guiding part is used to cooperate with the guiding body to realize the guiding function. For example, the guide body is a guide column structure, and the auxiliary guide part is a guide groove structure, that is, the guide part is a combination of a guide column and a guide groove, wherein the guide column plays a major role.
此外，滑动部分在相对导向主体滑动的过程中，可以是仅相对导向主体的一部分滑动，这部分即滑动区段，此时滑动部分的滑动范围仅限于滑动区段。举例而言，导向主体为棱柱结构，棱柱结构的中段制成为圆柱结构，使得滑动部分仅在圆柱结构的长度范围内滑动。In addition, during the sliding process of the sliding part relative to the guiding body, it may only slide relative to a part of the guiding body, and this part is the sliding section. At this time, the sliding range of the sliding part is limited to the sliding section. For example, the guide body is a prism structure, and the middle section of the prism structure is made into a cylinder structure, so that the sliding part can only slide within the length range of the cylinder structure.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述滑动部分还配置有滑动衬套，所述滑动部分借助于所述滑动衬套与所述滑动区段滑动配合。Regarding the aforementioned rear suspension assembly for a vehicle, in some embodiments, the sliding part is further configured with a sliding bush, and the sliding part is slidably engaged with the sliding section by means of the sliding bush.
通过为滑动部分配置滑动衬套，借助滑动衬套构造类滑动轴承结构，可以减轻滑动部分和滑动区段各自的磨损，还可以使滑动运动更顺畅。滑动衬套作为构造形成滑动部分的单体结构而存在。By providing the sliding part with a sliding bush and constructing a sliding bearing-like structure by means of the sliding bush, the respective wear of the sliding part and the sliding section can be reduced, and the sliding motion can be made smoother. The sliding bushing exists as a one-piece structure constructed to form the sliding part.
滑动衬套与滑动区段之间填充有润滑油或润滑脂。此外，滑动衬套可以一体成型，也可以制成分体结构，例如通过扣合连接构造形成完整的滑动衬套。Lubricating oil or grease is filled between the sliding bush and the sliding section. In addition, the sliding bushing can be integrally formed, or can be made into a split structure, for example, a complete sliding bushing can be formed through a snap-fit connection structure.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述滑动部分还配置有轴承，所述轴承包括内圈和外圈，所述外圈与所述滑动部分连接，所述内圈与所述滑动衬套连接，以便：所述滑动部分能够在竖直方向上相对所述滑动区段滑动的同时，还能够在水平方向上相对所述滑动衬套摆转。Regarding the aforementioned rear suspension assembly for vehicles, in some embodiments, the sliding part is further equipped with a bearing, and the bearing includes an inner ring and an outer ring, the outer ring is connected with the sliding part, and the inner The ring is connected with the sliding bush, so that the sliding part can slide relative to the sliding section in the vertical direction, and at the same time, can swing relative to the sliding bush in the horizontal direction.
通过设置轴承，可以使滑动部分自身构造形成转动副，这样一来，在车轮转向过程中，车轮受到的横向载荷和纵向载荷能够分别被转动副和滑动副吸收转化，从而进一步减小车架受到的冲击力，提升行车平稳性，提高乘车舒适度。By arranging bearings, the sliding part itself can be configured to form a rotating pair. In this way, during the steering process of the wheel, the lateral load and longitudinal load on the wheel can be absorbed and transformed by the rotating pair and sliding pair respectively, thereby further reducing the load on the frame. The impact force improves driving stability and ride comfort.
可以理解的是，轴承可以是球轴承或滚子轴承，滚子轴承可以是圆柱滚子轴承或圆锥滚子轴承。此外，轴承的个数可以是一个或多个轴承的组合。当轴承的个数为多个时，多个轴承之间沿竖直方向间隔设置，因此还可以在两个轴承之间设置用于限制轴承发生相对位移的结构，例如该结构可以是形成在滑动衬套上的、突出于滑动衬套表面的环形圈，和/或该结构可以是形成在滑动部分上的、突出于滑动部分内表面的环形圈。It can be understood that the bearings can be ball bearings or roller bearings, and the roller bearings can be cylindrical roller bearings or tapered roller bearings. In addition, the number of bearings may be a combination of one or more bearings. When the number of bearings is multiple, the plurality of bearings are arranged at intervals along the vertical direction, so a structure for limiting the relative displacement of the bearings can also be provided between the two bearings, for example, the structure can be formed in a sliding An annular ring on the bush protruding from the surface of the sliding bush, and/or the structure may be an annular ring formed on the sliding part protruding from the inner surface of the sliding part.
需要说明的是，轴承与滑动部分和滑动衬套的连接方式为过盈配合连接。It should be noted that the connection mode of the bearing, the sliding part and the sliding bush is an interference fit connection.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述固定部还设置有限位部分，所述限位部分设置于所述滑动区段，以便限定出所述活动部的滑动范围。Regarding the aforementioned rear suspension assembly for vehicles, in some embodiments, the fixed part is further provided with a limiting part, and the limiting part is arranged on the sliding section so as to limit the sliding range of the movable part .
通过在固定部设置限位部分，可以更好地限定出活动部的滑动范围，从而避免车轮在竖直方向上运动幅度过大而导致车体颠簸感明显。The sliding range of the movable part can be better limited by setting the limiting part on the fixed part, so as to avoid the excessive movement range of the wheel in the vertical direction, which will cause obvious bumpy feeling of the vehicle body.
限位部分的实现方式有多种。举例而言，限位部分可以是导向主体或导向部分自身形成的结构，也可以是通过粘接、焊接、螺接等方式连接至导向部分后形成的结构，还可以是以上两种情形的结合等。There are many ways to realize the limit part. For example, the limiting part may be a structure formed by the guide body or the guide part itself, or a structure formed after being connected to the guide part by bonding, welding, screwing, etc., or a combination of the above two situations wait.
对于上述的用于车辆的后悬挂组件，在一些实施方式中，所述固定 部还设置有减震部分，所述减震部分设置于所述滑动区段。Regarding the above-mentioned rear suspension assembly for a vehicle, in some embodiments, the fixing part is further provided with a shock absorbing part, and the shock absorbing part is provided in the sliding section.
通过设置减震部分，可以进一步减小车轮运动过程中对车架的冲击力，保证乘车舒适性。By setting the damping part, the impact force on the vehicle frame during the movement of the wheels can be further reduced to ensure the ride comfort.
减震部分的实现方式有多种。举例而言，减震部分为套设于滑动区段，且位于限位部分和滑动部分之间的弹簧，或者沿竖直观察，减震部分为设置于滑动部分滑动路径的上下游的活塞杆，或者可以是以上两种减震方式的组合，当然还可以是其他类型的能够实现减震效果的零部件及其组合。There are many ways to realize the damping part. For example, the damping part is a spring sleeved on the sliding section and located between the limiting part and the sliding part, or viewed vertically, the damping part is a piston rod arranged upstream and downstream of the sliding path of the sliding part , or can be a combination of the above two damping methods, and of course can also be other types of parts and combinations thereof that can achieve a damping effect.
在第二方面，本发明还提供了一种车辆，所述车辆配置有前述任一项技术方案所述的用于车辆的后悬挂组件。In a second aspect, the present invention also provides a vehicle, which is equipped with the rear suspension assembly for a vehicle described in any one of the preceding technical solutions.
可以理解的是，由于该车辆配置有前述任一项技术方案所述的用于车辆的后悬挂组件，因此具备前述后悬挂组件的所有技术效果，在此不再赘述。It can be understood that since the vehicle is equipped with the rear suspension assembly for vehicles described in any one of the foregoing technical solutions, it has all the technical effects of the foregoing rear suspension assembly, which will not be repeated here.

具体实施方式Detailed ways
本领域技术人员应当理解的是，这些实施方式仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.
另外，为了更好地说明本发明，在下文的具体实施方式中给出了众 多的具体细节。本领域技术人员应当理解，没有某些具体细节，本发明同样可以实施。In addition, in order to better illustrate the present invention, numerous specific details are given in the specific embodiments below. It will be understood by those skilled in the art that the present invention may be practiced without certain of the specific details.
需要说明的是，在本文中用到的方位术语如“前”、“后”、“上”、“下”等均以部件安装至车辆后车辆的前后方向为基准。在本文中提到的“纵”、“纵向”均以部件安装至车辆后的前后方向为基准，而“横”、“横向”则表示垂直于纵向方向。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。It should be noted that the orientation terms such as "front", "rear", "upper" and "lower" used herein are based on the front-rear direction of the vehicle after the components are installed on the vehicle. The "longitudinal" and "longitudinal" mentioned in this article are based on the front-rear direction after the component is installed on the vehicle, while "horizontal" and "transverse" mean perpendicular to the longitudinal direction. In addition, the terms "first" and "second" are used for descriptive purposes only, and should not be understood as indicating or implying relative importance.
在对本发明的方案进行说明之前，首先对车轮跳动易造成车辆侧倾的原因进行简单说明。本领域技术人员可以理解的是，对于麦弗逊悬挂***而言，车轮通过下控制臂枢转连接至车架，该枢转连接的转动中心线沿水平方向延伸，当车轮碾压到障碍物时，车轮受到的部分纵向载荷和横向载荷无法通过该转动副转化吸收，因而会在连接处形成纵向和横向加速度，使得车辆一侧的车轮和车架抬升，导致车身侧倾，降低行车稳定性。Before describing the solution of the present invention, firstly, a brief description will be given of the reasons why the wheel jump easily causes the vehicle to roll. Those skilled in the art can understand that, for the MacPherson suspension system, the wheel is pivotally connected to the vehicle frame through the lower control arm, and the rotation center line of the pivot connection extends along the horizontal direction. At this time, part of the longitudinal load and lateral load received by the wheel cannot be converted and absorbed by the rotating pair, so longitudinal and lateral acceleration will be formed at the joint, which will cause the wheel and frame on one side of the vehicle to lift, resulting in body roll and reduced driving stability. .
为了解决上述问题，本发明实施例提供了一种后悬挂组件，通过在车架上设置固定部，在车轮上设置活动部，使得车轮借助固定部与活动部之间的滑动连接至少实现沿竖直方向上的滑动运动，这样一来，当车轮转向或遇到障碍物时，障碍物会向车轮至少施加纵向载荷，一些情形下还会施加横向载荷，纵向载荷转移至活动部后会转化为活动部的竖向滑动运动，横向载荷会被活动部与固定部构成的滑动副吸收消化，从而将车轮的跳动运动转化为车轮的竖向滑动运动，对于车身而言，其侧倾中心与质心不会发生偏离，因此车辆不会发生侧倾，从而始终保持车轮定位参数的恒定，提升车身稳定性和抗侧倾能力。In order to solve the above problems, the embodiment of the present invention provides a rear suspension assembly, by setting the fixed part on the frame and the movable part on the wheel, so that the wheel can achieve at least vertical suspension through the sliding connection between the fixed part and the movable part. Sliding motion in the vertical direction, so that when the wheel turns or encounters an obstacle, the obstacle will apply at least a longitudinal load to the wheel, and in some cases a lateral load, which is transferred to the movable part and converted into For the vertical sliding motion of the movable part, the lateral load will be absorbed and digested by the sliding pair formed by the movable part and the fixed part, thus converting the beating motion of the wheel into the vertical sliding motion of the wheel. For the body, the roll center and the center of mass There will be no deviation, so the vehicle will not roll, so that the wheel alignment parameters will always be kept constant, and the stability of the body and the ability to resist roll will be improved.
下面参照附图来描述本发明的优选实施方式。Preferred embodiments of the present invention are described below with reference to the accompanying drawings.
实施例1Example 1
图1为本发明实施例提供的后悬挂组件的装配结构示意图；图2为本发明实施例提供的后悬挂组件中的滑动部分与导向部分的***示意图。FIG. 1 is a schematic diagram of the assembly structure of the rear suspension assembly provided by the embodiment of the present invention; FIG. 2 is an exploded schematic diagram of the sliding part and the guide part of the rear suspension assembly provided by the embodiment of the present invention.
本发明提供的后悬挂组件包括固定部和活动部，活动部与固定部滑动连接，连接后的活动部能够相对固定部沿竖直方向滑动。The rear suspension assembly provided by the present invention includes a fixed part and a movable part, the movable part is slidably connected to the fixed part, and the connected movable part can slide vertically relative to the fixed part.
如图1所示，固定部3包括导向部分30和连接部分31，导向部分30用于引导活动部2的运动，连接部分31用于将导向部分30固定连接到车架1上。导向部分30与连接部分31可以一体成型，也可以通过焊接、粘接、螺接等方式连接为一体结构。本实施例中，连接部分31与导向部分30一体成型，这与活动部2的滑动部分的设置方式是相关的，本实施例中的滑动部分设置为分体结构，可以方便地连接到该导向部分30，因此无需考虑连接部分31与导向部分30一体成型后与滑动部分的连接问题。导向部分30至少对应于滑动部分的位置制成为实心或空心的棱柱结构，该部分作为引导活动部2滑动的滑动区段300。As shown in FIG. 1 , the fixed part 3 includes a guiding part 30 and a connecting part 31 , the guiding part 30 is used to guide the movement of the movable part 2 , and the connecting part 31 is used to fix the guiding part 30 to the vehicle frame 1 . The guide part 30 and the connecting part 31 can be integrally formed, or can be connected as an integral structure by means of welding, bonding, screwing and the like. In this embodiment, the connecting part 31 and the guide part 30 are integrally formed, which is related to the arrangement of the sliding part of the movable part 2. The sliding part in this embodiment is set as a split structure, which can be easily connected to the guide part 30, so there is no need to consider the problem of connecting the connecting part 31 and the guiding part 30 to the sliding part after integrally formed. The guide part 30 is made into a solid or hollow prism structure at least corresponding to the position of the sliding part, and this part serves as a sliding section 300 for guiding the sliding of the movable part 2 .
如图2所示，本实施例中的活动部2包括滑动部分和滑动衬套22。滑动部分包括第一单体20和第二单体21扣合连接后形成的滑块结构，滑动衬套22设置于滑块结构与滑动区段300之间。具体地，第一单体20为条形块状结构，其一侧表面向内凹进形成与滑动衬套22的外周适配的第一凹陷区域(未标示)。第二单体21也为条形块状结构，其一侧表面向内凹进形成与滑动衬套22的外周适配的第二凹陷区域(未标示)。当第一单体20和第二单体21扣合时，第一凹陷区域和第二凹陷区域围设形成用于容纳滑动衬套22的容纳空间。在安装完成的情形下，滑动衬套22套设于滑动区段300外周，滑动衬套22的外表面与滑块结构的内表面过盈配合，滑动衬套22与滑动区段300之间填充有润滑脂。本实施例中的滑动衬套22制成为分体式，以与第一单体20和第二单体21相同的连接方式连接至滑动区段300，需要说明的是，图2中未对分体式滑动衬套22进行展示。As shown in FIG. 2 , the movable part 2 in this embodiment includes a sliding part and a sliding bush 22 . The sliding part includes a slider structure formed by fastening connection of the first unit 20 and the second unit 21 , and the sliding bushing 22 is disposed between the slider structure and the sliding section 300 . Specifically, the first unit 20 is a bar-shaped block structure, one side surface of which is inwardly recessed to form a first recessed area (not shown) adapted to the outer periphery of the sliding bush 22 . The second unit 21 is also a bar-shaped block structure, and one side surface thereof is recessed inwardly to form a second concave area (not shown) adapted to the outer periphery of the sliding bush 22 . When the first unit 20 and the second unit 21 are fastened together, the first recessed area and the second recessed area surround and form an accommodation space for accommodating the sliding bush 22 . When the installation is completed, the sliding bushing 22 is sleeved on the outer periphery of the sliding section 300, the outer surface of the sliding bushing 22 is in interference fit with the inner surface of the slider structure, and the gap between the sliding bushing 22 and the sliding section 300 is filled. There is grease. The sliding bushing 22 in this embodiment is made into a split type, and is connected to the sliding section 300 in the same connection manner as the first unit 20 and the second unit 21. It should be noted that the split type is not shown in FIG. 2 Slide bushing 22 is shown.
替代性地，滑动衬套22的两个端部还可以形成有限位凸台(未图示)，限位凸台分别与滑块结构的顶面和底面抵接，防止滑块结构与滑动衬套22之间发生轴向位移。Alternatively, the two ends of the sliding bushing 22 can also form limiting bosses (not shown), and the limiting bosses abut against the top surface and the bottom surface of the slider structure respectively to prevent the slider structure from colliding with the sliding bushing. Axial displacement occurs between the sleeves 22 .
为了将滑块结构的滑动运动限制在一定范围内，防止活动部2过度运动，本实施例中的滑动区段300的两个端部分别设置有限位板5，限位板包括位于滑块结构上方的上限位板和位于滑块结构下方的下限位板，使得滑块结构仅能在上限位板和下限位板限定出的区域内滑动。为了缓冲滑块结构的运动，在限位板5和滑块结构之间还设置有减震弹簧4。具 体地，在上限位板与滑块结构的顶面之间设置有第一减震弹簧(未标示)，在下限位板与滑块结构的底面之间设置有第二减震弹簧(未标示)。In order to limit the sliding movement of the slider structure within a certain range and prevent the movable part 2 from moving excessively, the two ends of the sliding section 300 in this embodiment are respectively provided with limiting plates 5, and the limiting plates include The upper upper limit plate and the lower limit plate located below the slider structure enable the slider structure to slide only in the area defined by the upper limit plate and the lower limit plate. In order to buffer the movement of the slider structure, a damping spring 4 is also arranged between the limiting plate 5 and the slider structure. Specifically, a first shock absorbing spring (not marked) is arranged between the upper limit plate and the top surface of the slider structure, and a second shock absorbing spring (not marked) is arranged between the lower limit plate and the bottom surface of the slider structure. ).
本实施例中的滑动部分与导向部分30之间仅能够实现竖向相对滑动，因此需要将滑动部分与转向节6通过转动副转动连接，从而在转向时实现车轮7的偏转。转向节6通过轮毂轴承与车轮7的轮毂固定连接。In this embodiment, only vertical relative sliding can be realized between the sliding part and the guide part 30 , so it is necessary to connect the sliding part and the steering knuckle 6 through a rotating pair so as to realize the deflection of the wheel 7 during steering. The steering knuckle 6 is fixedly connected with the hub of the wheel 7 through the hub bearing.
本实施例中，转向节6还连接有减震器8，减震器8沿竖直方向延伸，与固定部3配置的减震弹簧4组合形成双减震机构，能够进一步降低行车过程中的振动，提高车身稳定性，提升乘坐舒适性。In this embodiment, steering knuckle 6 is also connected with shock absorber 8, and shock absorber 8 extends along the vertical direction, and is combined with the shock absorber spring 4 that fixing part 3 is configured to form double shock absorber mechanism, can further reduce the shock absorber in driving process. Vibration improves body stability and ride comfort.
车辆在行驶过程中，车轮7碾压到障碍物后，会受到来自障碍物施加的横向载荷和纵向载荷，其中纵向载荷通过转向节6传递至活动部2，促使滑动部分相对导向部分30在竖直方向上运动，纵向载荷被吸收转化，而受到的横向载荷被转向节6和活动部2之间的转动副吸收，进而可以有效避免车辆侧倾，提升其抗侧倾能力。When the vehicle is running, after the wheel 7 is crushed against an obstacle, it will be subjected to lateral and longitudinal loads imposed by the obstacle, wherein the longitudinal load is transmitted to the movable part 2 through the steering knuckle 6, so that the sliding part moves vertically relative to the guide part 30. Moving in the vertical direction, the longitudinal load is absorbed and converted, and the received lateral load is absorbed by the rotating pair between the steering knuckle 6 and the movable part 2, thereby effectively avoiding the vehicle from rolling and improving its anti-rolling ability.
实施例2Example 2
本实施例中的固定部3与实施例1中的固定部3的设置方式相同，不同之处在于活动部2的设置方式。The arrangement of the fixed part 3 in this embodiment is the same as the arrangement of the fixed part 3 in the first embodiment, the difference lies in the arrangement of the movable part 2 .
本实施例中的活动部2包括滑动部分、滑动衬套22和轴承(未图示)，滑动部分包括第一单体20和第二单体21扣合形成的滑块结构，轴承包括内圈和外圈，外圈与滑块结构的内表面连接，内圈与滑动衬套22的外表面连接。通过设置轴承，在滑动衬套22与滑块结构之间增加了转动副，这样一来，滑块结构既能够借助于滑动衬套22在竖直方向上相对滑动区段300滑动，还能够借助轴承在水平方向上相对滑动衬套22摆转，从而进一步增强悬挂组件吸收外部冲击力的能力。The movable part 2 in this embodiment includes a sliding part, a sliding bush 22 and a bearing (not shown), the sliding part includes a slider structure formed by fastening the first unit 20 and the second unit 21, and the bearing includes an inner ring and the outer ring, the outer ring is connected with the inner surface of the slider structure, and the inner ring is connected with the outer surface of the sliding bush 22. By arranging the bearing, a rotating pair is added between the sliding bush 22 and the slider structure, so that the slider structure can not only slide relative to the sliding section 300 in the vertical direction by means of the sliding bush 22, but also can The bearing pivots relative to the sliding bush 22 in the horizontal direction, thereby further enhancing the ability of the suspension assembly to absorb external impact.
实施例3Example 3
本实施例与实施例1和实施例3的不同之处在于，本实施例中的导向主体上的滑动区段300制成为圆柱结构，相应地，滑动衬套22与滑块结构也制成与该圆柱结构适配的结构，在安装完成的状态下，滑块结构借助于滑动衬套22可相对滑动区段300上下滑动，同时还可借助于滑动衬套22相对滑动区段300摆转，从而更好地转化吸收车轮7受到的冲击力，提升车身的抗侧倾能力。The difference between this embodiment and Embodiment 1 and Embodiment 3 is that the sliding section 300 on the guide body in this embodiment is made into a cylindrical structure, and correspondingly, the structure of the sliding bush 22 and the slider is also made into the same structure. The structure adapted to the cylindrical structure, when the installation is completed, the slider structure can slide up and down relative to the sliding section 300 by means of the sliding bush 22, and can also swing relative to the sliding section 300 by means of the sliding bush 22, Thereby, the impact force received by the wheel 7 can be better converted and absorbed, and the anti-rolling ability of the vehicle body can be improved.
