Definitions
- the present invention relates to a tire conversion system including a rolling device such as a deformed wheel, a rubber crawler wheel, and a triangular track wheel, and more particularly to an anti-rollover system for a tire conversion system.
- the tire conversion system usually does not have the same peripheral symmetry as a round wheel.
- the position of the center point of the tire conversion system will be displaced back and forth, and the front and rear ends will be tilted up and down in the longitudinal direction. Lightly, the tire conversion system and the vehicle body interfere, and the tire conversion system is vertically overturned, which threatens driving safety.
- the fixed structure is complicated, and the knuckle of the vehicle is At the time of manufacture, it is usually not considered to leave a lateral force redundancy for the tire conversion system, the lateral load capacity is insufficient, and the space reserved for the additional fixture on the steering knuckle is insufficient, even if the connection is generally anti-flip Structure, the impact of the ground obstacle on the tire conversion system will also directly affect the knuckle of the vehicle, resulting in a sharp increase in the lateral moment on the knuckle, reducing the safety of the steering structure and the safety of the vehicle.
- the object of the present invention is to provide a tire conversion system anti-flipping method and structure that is more reasonable and stable, has a simpler and lighter structure, and does not affect the performance of the vehicle itself.
- the center point of the ground contact below the central axis of the drive wheel connected to the vehicle body is in a non-fixed state relative to the vehicle body position, and the center point of the touch ground has a front-rear displacement phenomenon. Both ends also have up and down tilting in the vertical direction. Therefore, as long as the front and rear displacement of the center of the tire conversion system is eliminated or the up and down tilting of the front and rear ends of the tire conversion system is eliminated, the flipping movement of the tire conversion system can be eliminated. .
- the present invention can adopt the following two options:
- the first solution is the triangular fixing method: a virtual triangle with a rigid three-sided force structure is constructed between the vehicle body and the tire conversion system, and is converted from the tire above the vertical contact point of the driving shaft of the tire conversion system.
- the wheel bridge of the system extends a rigid beam to the intersection of the plumb lines of the vehicle kingpin, which should be designed to withstand the full stress of the wheel body, at which the anti-roll bar and beam can be horizontally rotated
- the movable pin is connected to connect the anti-roll bar to the vehicle body and
- the kingpin is fixed on the vehicle body with a certain distance in the longitudinal direction, and it is noted that the anti-roll bar does not occupy the steering space of the front wheel of the vehicle, so that a rigid body is used as a longitudinal line between the tire conversion system and the vehicle body.
- the rigid tire conversion system acts as a vertical line and the anti-rolling bar acts as a rigid triangular structure of the diagonal line, since the warp at the front and rear ends of the tire conversion system changes the distance from the intersection of the beam and the main pin plumb line to the vehicle body, and If the anti-rolling rod is made of non-retractable rigid material, the three edges of the triangular structure are rigid, and the distance between the intersection of the beam and the lead pin of the main pin to the vehicle body will not change, and the tire conversion system is prevented.
- the lever is made of a rigid material with sufficient strength, so that the distance from the traverse intersection to the fixed point of the vehicle body no longer occurs, so that the tire conversion system is no longer tilted back and forth and up and down, so the virtual triangular rigidity is adopted.
- the structure of the fixed method can effectively fix the tire conversion system; the triangular fixing scheme enables the tire conversion system including the deformed wheel and the triangular track wheel , When fixed to the vehicle body, having an extremely simple and reliable anti-inverted structure. Due to the stability of the triangle, such a rigid triangular fixed structure is applied between the tire conversion system and the vehicle body, and the simplest structure can be used to ensure the smooth fixation of the relative position between the tire conversion system and the vehicle body.

- the beam extending from the wheel body extends laterally from the central contact location on the tire conversion system to the centerline intersection of the main line of the vehicle body pin, and is connected to the vehicle body through the anti-roll bar at the cross-linking point.
- the beam extending from the wheel body should be able to withstand the maximum stress of the wheel body and transmit the stress to the vehicle body through the anti-roll bar.
- the intersection of the plumb line of the main body pin and the beam pin should be as close as possible to the center point of the horizontal steering of the wheel. Otherwise, the wheel will have displacement before or after the wheel, which increases the steering power consumption.
- the intersection of the plumb line of the body pin and the beam pin can be placed as close as possible to the longitudinal center point of the tire conversion system. The closer the virtual intersection is to the touch point, the smaller the horizontal fan-shaped surface drawn by the virtual intersection and the wheel touch point at the time of turning, and the smaller the dynamic displacement of the wheel body before and after the tire conversion system.
- the second solution is a two-point lateral fixing method: connecting the vertical line of the anti-rolling lever under the main pin of the vehicle body to the intersection of the beam extending from the wheel body with a rotatable pin shaft, and then turning the rigid anti-rolling
- the tie rod is connected to the vehicle body by at least two fixed points to any part of the vehicle body that can be stressed, or even connected to the lateral position of the vehicle body parallel to the beam, and then the anti-roll bar is fastened to the vehicle body.
- At least two points on the anti-roll bar can be fixedly connected with the vehicle body to form a horizontal fixed anti-rolling bar which is non-swingable with respect to the vehicle body, and the other end of the anti-roll bar can be horizontally rotatably connected to the wheel body.
- the anti-roll bar itself is not swingable relative to the car body, the anti-roll bar itself is used to withstand the stress of the up and down tilt of the tire conversion system and the impact force of the front and rear displacement. At this time, it is necessary to pay attention to the anti-roll bar. The strength of its lateral force.
- the solution needs at least two anti-rollover fixed stress points at the connection with the vehicle body, and the anti-roll bar in the solution can be parallel to the transverse direction of the vehicle body with the beam on the tire conversion system, preventing The pull rod can be fixed in parallel with the body itself.
- the anti-roll bar in this solution can also bear the lateral moment transmitted by the wheel body, so it is necessary to enhance the lateral force strength of the anti-roll bar.
- the two-point fixing method uses two points to fix the characteristics of one line, fixes the anti-rolling rod on the vehicle body, and then sets a beam extending from the wheel body bridge above the center of the wheel center of the tire conversion system wheel body. Extending the beam to the intersection of the plumb lines of the main body pin of the vehicle body. At the intersection, the beam and the anti-roll bar are connected by a pin shaft in a relatively horizontal manner, since the other end of the anti-roll bar is The principle of fixing the line by two points is fixed on the vehicle body. Therefore, the movable joint of the anti-rolling rod and the beam can only rotate relative to the horizontal direction of the connecting pin shaft, and cannot swing back and forth, thereby effectively limiting the front and rear displacement of the tire conversion system. To prevent the tire conversion system from flipping.

Description
本发明涉及包括变形车轮、橡胶履带轮以及三角履带轮等滚动装置在内的轮胎转换***，更确切地说，涉及轮胎转换***的防翻转***。The present invention relates to a tire conversion system including a rolling device such as a deformed wheel, a rubber crawler wheel, and a triangular track wheel, and more particularly to an anti-rollover system for a tire conversion system.
轮胎转换***通常不具备圆形车轮一样的周边对称性，车辆行驶当中，刹车和遭遇障碍时，轮胎转换***的触地中心点位置会发生前后位移，其前后两端会沿纵向上下翘簸，轻则造成轮胎转换***和车体干涉，重则造成轮胎转换***纵向翻覆，威胁行车安全。The tire conversion system usually does not have the same peripheral symmetry as a round wheel. When the vehicle is running, braking and encountering obstacles, the position of the center point of the tire conversion system will be displaced back and forth, and the front and rear ends will be tilted up and down in the longitudinal direction. Lightly, the tire conversion system and the vehicle body interfere, and the tire conversion system is vertically overturned, which threatens driving safety.
目前的轮胎转换***，如变形车轮或三角履带轮，以及其它履带轮，当作为轮胎转换***使用时，这些***目前使用的防翻转***结构复杂，受力不合理，安全性能差，特别是在需要作转向运动的前轮上，为了防止***在行进中翻覆，通常是采用将轮子一端或前后两端固定在车辆主销的转向节上方或下方，其固定结构复杂，加之车辆的转向节在制造时通常并未考虑过为轮胎转换***留下横向受力冗余量，其横向承力的亢余度不足，转向节上为附加固定件预留的空间也不足，即便连接上普通防翻转结构，地面障碍对轮胎转换***的冲击力也将直接作用于车辆的转向节上，导致转向节上的横向力矩暴增，降低了转向结构的安全性和车辆行驶的安全性。Current tire conversion systems, such as deformed wheels or triangular track wheels, and other track wheels, when used as a tire conversion system, the anti-flip systems currently used in these systems are complex in structure, unreasonable in force, and poor in safety, especially in On the front wheel that needs to be used for steering movement, in order to prevent the system from overturning during travel, it is usually used to fix one end of the wheel or the front and rear ends above or below the knuckle of the kingpin of the vehicle. The fixed structure is complicated, and the knuckle of the vehicle is At the time of manufacture, it is usually not considered to leave a lateral force redundancy for the tire conversion system, the lateral load capacity is insufficient, and the space reserved for the additional fixture on the steering knuckle is insufficient, even if the connection is generally anti-flip Structure, the impact of the ground obstacle on the tire conversion system will also directly affect the knuckle of the vehicle, resulting in a sharp increase in the lateral moment on the knuckle, reducing the safety of the steering structure and the safety of the vehicle.
发明内容Summary of the invention
本发明的目的是提供一种受力更合理稳定，结构更简洁轻便，同时又不影响车辆自身性能的轮胎转换***防翻转方法和结构。The object of the present invention is to provide a tire conversion system anti-flipping method and structure that is more reasonable and stable, has a simpler and lighter structure, and does not affect the performance of the vehicle itself.
当轮胎转换***在翘簸和前后摇晃时，其与车体连接的驱动轮中心轴下方的触地中心点相对车***置处于非固定状态，其触地中心点会有前后位移现象，其前后两端在垂直方向上也会有上下翘簸现象，因此，只要消除轮胎转换***触地中心点的前后位移或消除轮胎转换***前后两端的上下翘簸现象，即可消除轮胎转换***的翻转移动。When the tire conversion system is tilted and swayed back and forth, the center point of the ground contact below the central axis of the drive wheel connected to the vehicle body is in a non-fixed state relative to the vehicle body position, and the center point of the touch ground has a front-rear displacement phenomenon. Both ends also have up and down tilting in the vertical direction. Therefore, as long as the front and rear displacement of the center of the tire conversion system is eliminated or the up and down tilting of the front and rear ends of the tire conversion system is eliminated, the flipping movement of the tire conversion system can be eliminated. .
为此，本发明可以采用以下两种方案：To this end, the present invention can adopt the following two options:
第一种方案是三角固定法：是在车体和轮胎转换***之间，构建一个有刚性三边受力结构的虚拟三角形，在轮胎转换***的驱动轴心的垂直触地点上方，从轮胎转换***的轮桥架延伸一个刚性横梁到车辆主销的铅垂线交叉点上，所述横梁应设计成能承受轮体的全部应力，在所述交叉点上将防翻拉杆和横梁用可水平转动的活动销轴连接起来，将此防翻拉杆连接到车体上与
主销在纵向上有一定间距的车体上固定，并注意让此防翻拉杆不占用车辆前轮的转向空间，这样，就在轮胎转换***和车体间形成一个由刚性车体充当纵向线和刚性轮胎转换***充当垂向线以及防翻拉杆充当斜向线的刚性三角结构，由于轮胎转换***前后两端的翘簸会改变横梁与主销铅垂线的交叉点到车体的距离，而如果防翻拉杆采用不可伸缩的刚性材料，则这个三角结构的三个边线就都是刚性的，横梁与主销铅垂线的交叉点到车体的距离就不会改变，轮胎转换***的防翻拉杆只要采用足够强度的刚性材料，就不再出现从横垂交叉点到车体固定点的距离变化现象，因此能确保轮胎转换***不再前后翘簸和上下翻覆，因而采用该虚拟三角形刚性固定法的结构，能有效固定轮胎转换***；该三角固定方案使包括变形车轮和三角履带轮在内的轮胎转换***，在与车体固定时，具有了极简单又稳定可靠的防翻转结构。由于三角形具有稳定性，这样一种刚性三角固定结构应用在轮胎转换***和车体之间，能用最简便的结构确保轮胎转换***和车体间的相对位置的平稳固定。The first solution is the triangular fixing method: a virtual triangle with a rigid three-sided force structure is constructed between the vehicle body and the tire conversion system, and is converted from the tire above the vertical contact point of the driving shaft of the tire conversion system. The wheel bridge of the system extends a rigid beam to the intersection of the plumb lines of the vehicle kingpin, which should be designed to withstand the full stress of the wheel body, at which the anti-roll bar and beam can be horizontally rotated The movable pin is connected to connect the anti-roll bar to the vehicle body and
The kingpin is fixed on the vehicle body with a certain distance in the longitudinal direction, and it is noted that the anti-roll bar does not occupy the steering space of the front wheel of the vehicle, so that a rigid body is used as a longitudinal line between the tire conversion system and the vehicle body. And the rigid tire conversion system acts as a vertical line and the anti-rolling bar acts as a rigid triangular structure of the diagonal line, since the warp at the front and rear ends of the tire conversion system changes the distance from the intersection of the beam and the main pin plumb line to the vehicle body, and If the anti-rolling rod is made of non-retractable rigid material, the three edges of the triangular structure are rigid, and the distance between the intersection of the beam and the lead pin of the main pin to the vehicle body will not change, and the tire conversion system is prevented. As long as the lever is made of a rigid material with sufficient strength, the distance from the traverse intersection to the fixed point of the vehicle body no longer occurs, so that the tire conversion system is no longer tilted back and forth and up and down, so the virtual triangular rigidity is adopted. The structure of the fixed method can effectively fix the tire conversion system; the triangular fixing scheme enables the tire conversion system including the deformed wheel and the triangular track wheel , When fixed to the vehicle body, having an extremely simple and reliable anti-inverted structure. Due to the stability of the triangle, such a rigid triangular fixed structure is applied between the tire conversion system and the vehicle body, and the simplest structure can be used to ensure the smooth fixation of the relative position between the tire conversion system and the vehicle body.
在需要作转向运动的轮胎转换***上，防翻拉杆通过销轴在横梁和主销铅垂线的交叉点上连接，然后在水平面方向上呈一定的夹角与车体连接，其水平面夹角的确定，以防翻拉杆不与转向到极限时的轮胎转换***干涉而又尽量保持纵向趋势为原则。In a tire conversion system that requires steering motion, the anti-roll bar is connected at the intersection of the beam and the main pin plumb line through the pin, and then connected to the vehicle body at a certain angle in the horizontal direction, and the horizontal plane angle The determination is made to prevent the tumbler from interfering with the tire conversion system when steering to the limit while maintaining the longitudinal tendency as much as possible.
轮体伸出的横梁从轮胎转换***上的中心触地点位置横向延伸到车体主销的铅垂线中心交联处，并在交联处通过防翻拉杆与车体连接。轮体伸出的横梁应该能承受轮体的最大应力，并能通过防翻拉杆将应力传递到车体。The beam extending from the wheel body extends laterally from the central contact location on the tire conversion system to the centerline intersection of the main line of the vehicle body pin, and is connected to the vehicle body through the anti-roll bar at the cross-linking point. The beam extending from the wheel body should be able to withstand the maximum stress of the wheel body and transmit the stress to the vehicle body through the anti-roll bar.
车体主销的铅垂线与横梁销轴的交叉点，应尽量靠近车轮水平转向的中心点，否则车轮在转向时轮体会有或前或后的位移，增加转向功耗。车体主销的铅垂线与横梁销轴的交叉点，可以设置在尽量靠近轮胎转换***的纵向触地中心点位置。虚拟交叉点离触地点越近，转向时的虚拟交叉点和轮体触地点划出的水平扇形面越小，轮胎转换***的轮体前后动态位移量越小。The intersection of the plumb line of the main body pin and the beam pin should be as close as possible to the center point of the horizontal steering of the wheel. Otherwise, the wheel will have displacement before or after the wheel, which increases the steering power consumption. The intersection of the plumb line of the body pin and the beam pin can be placed as close as possible to the longitudinal center point of the tire conversion system. The closer the virtual intersection is to the touch point, the smaller the horizontal fan-shaped surface drawn by the virtual intersection and the wheel touch point at the time of turning, and the smaller the dynamic displacement of the wheel body before and after the tire conversion system.
第二种方案是两点横向固定法：将防翻拉杆在车体主销下的铅垂线与轮体伸出的横梁的交叉点部位用可转动的销轴连接，再将刚性的防翻拉杆在车体上用至少两个固定点连接到车体可受力的任意部位，甚至可以连接到与横梁平行的车体横向位置上，然后，再将防翻拉杆与车体作紧固连接，为此可在防翻拉杆上设置至少两个点与车体进行固定连接，形成一个相对车体不可摆动的横向固定防翻拉杆，防翻拉杆另一端可水平转动地活动连接在轮体伸出的横梁的交叉点上，因为防翻拉杆本身相对车体不可摆动，用防翻拉杆本身来承受轮胎转换***上下翘簸的应力和前后位移的冲击力，此时，需要注意增强防翻拉杆本身的横向受力的强度。该方案与第一个方案的不同点在
于，该方案需要防翻拉杆在与车体连接处至少有两个防翻固定受力点，该方案中的防翻拉杆可以与轮胎转换***上的横梁处于相对车体横向平行的位置，防翻拉杆可与车体本身呈横向平行固定。该方案中的防翻拉杆除了要承受轮体传递的推力和拉力，还要能承受轮体传递的横向力矩，因此需要相应增强防翻拉杆的横向受力强度。The second solution is a two-point lateral fixing method: connecting the vertical line of the anti-rolling lever under the main pin of the vehicle body to the intersection of the beam extending from the wheel body with a rotatable pin shaft, and then turning the rigid anti-rolling The tie rod is connected to the vehicle body by at least two fixed points to any part of the vehicle body that can be stressed, or even connected to the lateral position of the vehicle body parallel to the beam, and then the anti-roll bar is fastened to the vehicle body. For this purpose, at least two points on the anti-roll bar can be fixedly connected with the vehicle body to form a horizontal fixed anti-rolling bar which is non-swingable with respect to the vehicle body, and the other end of the anti-roll bar can be horizontally rotatably connected to the wheel body. At the intersection of the beam, because the anti-roll bar itself is not swingable relative to the car body, the anti-roll bar itself is used to withstand the stress of the up and down tilt of the tire conversion system and the impact force of the front and rear displacement. At this time, it is necessary to pay attention to the anti-roll bar. The strength of its lateral force. The difference between this program and the first one is
Therefore, the solution needs at least two anti-rollover fixed stress points at the connection with the vehicle body, and the anti-roll bar in the solution can be parallel to the transverse direction of the vehicle body with the beam on the tire conversion system, preventing The pull rod can be fixed in parallel with the body itself. In addition to the thrust and tension transmitted by the wheel body, the anti-roll bar in this solution can also bear the lateral moment transmitted by the wheel body, so it is necessary to enhance the lateral force strength of the anti-roll bar.
所述两点固定法，利用两点可以固定一线的特性，将防翻拉杆固定在车体上，再在轮胎转换***轮体的触地点中心上方，设置一个从轮体轮桥延伸出来的横梁，将横梁延伸到车体主销的铅垂线交叉点上，在所述交叉点上，横梁与防翻拉杆以能相对水平转动的方式用销轴连接起来，由于防翻拉杆的另一端是用两点固定一线的原理固定在车体上，因此，防翻拉杆与横梁的活动连接处只可绕连接销轴相对水平转动，不能前后摆动，因此能有效限制轮胎转换***的前后位移，起到防止轮胎转换***翻转的作用。The two-point fixing method uses two points to fix the characteristics of one line, fixes the anti-rolling rod on the vehicle body, and then sets a beam extending from the wheel body bridge above the center of the wheel center of the tire conversion system wheel body. Extending the beam to the intersection of the plumb lines of the main body pin of the vehicle body. At the intersection, the beam and the anti-roll bar are connected by a pin shaft in a relatively horizontal manner, since the other end of the anti-roll bar is The principle of fixing the line by two points is fixed on the vehicle body. Therefore, the movable joint of the anti-rolling rod and the beam can only rotate relative to the horizontal direction of the connecting pin shaft, and cannot swing back and forth, thereby effectively limiting the front and rear displacement of the tire conversion system. To prevent the tire conversion system from flipping.
所述三角固定法，是利用三角形的稳定特性，在靠近轮胎转换***轮体的触地点中心位置上方，设置一个从轮体延伸出来的横梁，将横梁延伸到车体主销的铅垂线交叉点上，在所述主销铅垂线和横梁的交叉点上，将横梁与防翻拉杆用水平转动销轴连接起来，再将防翻拉杆的另一端，尽量与车辆上的主销保持一定的水平纵向距离并用至少一个固定点固定在车体上。The triangular fixing method utilizes the stability characteristic of the triangle, and a beam extending from the wheel body is disposed above the center position of the contact point of the wheel body of the tire conversion system, and the beam extends to the vertical line of the main body pin of the vehicle body. Point, at the intersection of the main pin plumb line and the beam, connect the beam and the anti-rolling lever with the horizontal rotation pin, and then keep the other end of the anti-roll bar as close as possible to the king pin on the vehicle. The horizontal longitudinal distance is fixed to the vehicle body with at least one fixed point.
所述防翻拉杆在接近车体处比接近横梁处更粗实宽大。The anti-roll bar is thicker and wider at the approaching of the vehicle body than near the cross member.

实施例一 Embodiment 1
参考图1、图2和图6所示的轮胎转换***防翻转两点固定法在三角履带轮和越野车上的应用，在三角履带轮5的触地中心点位置上方，从轮体的轮桥6上延伸一个横梁2到车辆主销8的铅垂线9交叉点10上，在交叉点10上安放一个可水平转动的销轴3，将防翻拉杆1和横梁2通过转动销轴3连接在一起，将防翻拉杆1在车体7上的固定点4与车辆主销8拉开一定距离，再将防翻拉杆1以与车体7横向平行状态固定在越野车车体7上。防翻拉杆1位于轮体转轴的铅垂面上。防翻拉杆1的固定点4至少是两个，采用这种两点固定法的防翻拉杆1，其本身需要有足够的刚性强度并能承受较强的横向剪切力。Referring to the application of the tire reversing two-point fixing method of the tire conversion system shown in FIG. 1, FIG. 2 and FIG. 6 on the triangular track wheel and the off-road vehicle, the wheel of the wheel body is located above the grounding point of the cam track 5 A cross member 2 is extended on the bridge 6 to the intersection point 10 of the vertical line 9 of the vehicle kingpin 8, and a horizontally rotatable pin 3 is placed on the intersection 10, and the anti-roll bar 1 and the cross member 2 are passed through the rotating pin shaft 3. Connected together, the fixed point 4 of the anti-roll bar 1 on the vehicle body 7 is pulled away from the vehicle kingpin 8 by a certain distance, and the anti-roll bar 1 is fixed on the off-road vehicle body 7 in a state parallel to the vehicle body 7 in a lateral parallel direction. . The anti-roll bar 1 is located on the vertical plane of the wheel shaft. The anti-roll bar 1 has at least two fixing points 4, and the anti-roll bar 1 using the two-point fixing method itself needs to have sufficient rigidity and can withstand strong lateral shearing force.
实施例二 Embodiment 2
参考图3、图4、图5和图6所示的胎转换***防翻转三角固定法在三角履带轮5和越野车上的应用，在三角履带轮5的触地中心点位置上方，从轮体的轮桥6上延伸一个横梁2到车辆主销8的铅垂线9的交叉点10上，在所述交叉点10上安放水平转动的销轴3，再将防翻拉杆1和横梁2通过转动的销轴3连接在一起，让防翻拉杆1的固定点4与车辆主销8在水平方向上拉开一定距离，将防翻拉杆1斜向固定在越野车车体7的底盘上。防翻拉杆1与轮体转轴的铅垂面倾斜。防翻拉杆1斜向固定是为了避免三角履带轮5在绕主销8转动时与防翻拉杆1发生干涉，在防翻拉杆1与三角履带轮5的轮体不干涉的情况下，尽量保持防翻拉杆1的纵向趋势，以减少防翻拉杆1上的横向应力，然后，再用螺杆将防翻拉杆的另一端固定连接在越野车车体7上。Referring to the application of the anti-rolling cam fixing method of the tire conversion system shown in FIG. 3, FIG. 4, FIG. 5 and FIG. 6 on the cam track 5 and the off-road vehicle, above the grounding point of the cam track 5, the wheel is taken from the wheel. On the body wheel bridge 6, a cross beam 2 is extended to the intersection 10 of the vertical line 9 of the vehicle kingpin 8, at which the horizontally rotating pin 3 is placed, and the anti-roll bar 1 and the beam 2 are placed. The rotating pin 3 is connected together, and the fixing point 4 of the anti-roll bar 1 is pulled away from the vehicle king pin 8 by a certain distance in the horizontal direction, and the anti-roll bar 1 is obliquely fixed on the chassis of the off-road vehicle body 7. . The anti-roll bar 1 is inclined with respect to the vertical plane of the wheel shaft. The anti-rolling bar 1 is fixed obliquely in order to prevent the cam track 5 from interfering with the anti-roll bar 1 when rotating around the king pin 8, and as far as possible, the anti-roll bar 1 and the wheel of the cam track 5 do not interfere with each other. The longitudinal tendency of the anti-roll bar 1 is to reduce the lateral stress on the anti-roll bar 1, and then the other end of the anti-roll bar is fixedly connected to the off-road vehicle body 7 by a screw.
如图5所示，防翻拉杆1可以至少是两根，从主销8铅垂线9和横梁2交叉点10上通过销轴3连接分别固定在车体7前后的不同固定点4上。
As shown in FIG. 5, the anti-roll bar 1 can be at least two, and is fixed from the main pin 8 vertical line 9 and the beam 2 intersection 10 to the different fixing points 4 on the front and rear of the vehicle body 7 via the pin 3 connection.
如图6所示，轮胎转换***防翻转两点固定法和三角固定法可以同时应用在车体上。As shown in Fig. 6, the tire conversion system anti-flip two-point fixing method and the triangular fixing method can be simultaneously applied to the vehicle body.
根据上述实施例可以看出，本发明采用从轮体轮桥向交叉点位置延伸横梁2，使之与车辆转向主销8的铅垂线相交叉，并从这个交叉点用可水平转动的销轴3连接防翻拉杆1并将防翻拉杆1固定在车体上的方法，该方法相较传统的防翻转原理，结构更简单，连接的方式更安全和稳定，生产制造方便，安装和拆卸都更方便容易。As can be seen from the above embodiments, the present invention employs the extension of the beam 2 from the wheel wheel bridge to the intersection point to intersect the plumb line of the vehicle steering kingpin 8, and from which the horizontally rotatable pin is used. The method is that the shaft 3 is connected with the anti-roll rod 1 and the anti-rolling rod 1 is fixed on the vehicle body. Compared with the traditional anti-flip principle, the method is simpler in structure, the connection method is safer and more stable, and the manufacturing is convenient, installation and disassembly. It is more convenient and easy.
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
What has been described above is only some embodiments of the invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and scope of the invention.
