Description
本发明属于车辆减震技术领域,尤其涉及一种可量化控制减震力度的车辆减震***。The invention belongs to the technical field of vehicle damping, and in particular relates to a vehicle damping system that can quantitatively control the damping intensity.
为了提高车辆行驶或骑行过程中的舒适度,减少因震动对车辆零件的磨损,一般的车辆都配置有减震***。然而,减震***经过长时间使用后,由于起缓冲作用的部件的弹力会减弱,从而导致减震能力也逐渐减弱。目前对于此类情况,只好通过维修手段来矫正或更换缓冲部件。这显然会增加维修成本,并且也影响车辆的正常使用。In order to improve the comfort during vehicle driving or riding and reduce the wear and tear on vehicle parts due to vibration, most vehicles are equipped with a shock absorption system. However, after long-term use of the shock-absorbing system, the elasticity of the buffering components will weaken, resulting in a gradual weakening of the shock-absorbing capability. At present, for such situations, the only way to correct or replace the buffer parts is through maintenance methods. This will obviously increase maintenance costs and also affect the normal use of the vehicle.
另一方面,车辆在行驶或骑行过程中,会遇到平坦、泥泞、凸凹不平等多种路面。对于不同的路面,对车辆减震要求不同。比如,对于凸凹不平的路面则需要较大的减震力度,而对于平坦的路面,则只需要很小的减震力度。On the other hand, vehicles will encounter a variety of uneven road surfaces including flat, muddy, and uneven surfaces while driving or riding. Different road surfaces have different shock absorption requirements for vehicles. For example, for uneven road surfaces, a greater shock absorption force is required, while for flat roads, only a small shock absorption force is required.
目前的车辆出厂后,其减震力度不能调节。不能根据不同的路况匹配不同的减震力度。如果在平坦的路面,弹簧弹性过大,会导致车辆上下晃动,不利于行驶或骑行安全。如果在凸凹不平的路面,弹簧阻尼力过大,减震力度不足,则会导致车辆颠簸,影响车上人员的舒适度,并且会加快车辆零件的损耗速度。After the current vehicle leaves the factory, its shock absorption strength cannot be adjusted. Different shock absorption strengths cannot be matched according to different road conditions. If the spring elasticity is too large on a flat road, it will cause the vehicle to shake up and down, which is not conducive to driving or riding safety. If the spring damping force is too large and the shock absorption strength is insufficient on uneven roads, it will cause the vehicle to bump, affect the comfort of the people on the vehicle, and accelerate the wear and tear of vehicle parts.

实施例一:Example 1:
请参看图1及图2,示出了本实施例一提供的一种可量化控制减震力度的车辆减震***,包括齿轮1、安装轴2、车架纵杆3、上滑动套筒4、下滑动套筒5、流体式弹簧6、支撑杆7、压力传感器8、气压控制装置9以及处理器。Please refer to Figures 1 and 2, which illustrates a vehicle damping system that can quantitatively control the damping intensity provided in the first embodiment, including a gear 1, a mounting shaft 2, a frame longitudinal rod 3, and an upper sliding sleeve 4 , lower sliding sleeve 5, fluid spring 6, support rod 7, pressure sensor 8, air pressure control device 9 and processor.
安装轴2沿齿轮的轴向方向穿设于齿轮1上,车架纵杆3的底端与上滑动套筒4的顶端固定连接,支撑杆7的顶端与下滑动套筒5的底端固定连接,支撑杆7的底端与安装轴2转动连接。The installation shaft 2 is passed through the gear 1 along the axial direction of the gear. The bottom end of the frame longitudinal rod 3 is fixedly connected to the top end of the upper sliding sleeve 4. The top end of the support rod 7 is fixed to the bottom end of the lower sliding sleeve 5. connection, the bottom end of the support rod 7 is rotationally connected to the installation shaft 2.
上滑动套筒4内部具有第一腔体40,第一腔体40的底端具有开口,下滑动套筒5内部具有第二腔体50,第二腔体50的顶端具有开口,上滑动套筒4的底端与下滑动套筒5的顶端相互嵌套,构成供上滑动套筒4上、下滑动的导向结构。The upper sliding sleeve 4 has a first cavity 40 inside, and the bottom end of the first cavity 40 has an opening. The lower sliding sleeve 5 has a second cavity 50 inside, and the top of the second cavity 50 has an opening. The upper sliding sleeve The bottom end of the barrel 4 and the top end of the lower sliding sleeve 5 are nested in each other to form a guide structure for the upper sliding sleeve 4 to slide up and down.
流体式弹簧6包括缸体61以及活塞杆62,活塞杆62的顶端抵顶第一腔体40的顶壁;缸体61固定在第二腔体50的底壁上。流体式弹簧6为气弹簧,压力控制装置9通过控制气缸体61内部的气压,控制活塞杆62抵顶第一腔体40顶壁的压力大小。The fluid spring 6 includes a cylinder 61 and a piston rod 62. The top of the piston rod 62 abuts the top wall of the first cavity 40; the cylinder 61 is fixed on the bottom wall of the second cavity 50. The fluid spring 6 is a gas spring, and the pressure control device 9 controls the pressure of the piston rod 62 against the top wall of the first cavity 40 by controlling the air pressure inside the cylinder 61 .
在其他实施方式中,流体式弹簧6也可以采用液压弹簧,压力控制装置9通过控制液压弹簧缸体内部的液体压力,控制液压弹簧输出的弹力大小。In other embodiments, the fluid spring 6 can also be a hydraulic spring, and the pressure control device 9 controls the elastic force output by the hydraulic spring by controlling the liquid pressure inside the hydraulic spring cylinder.
压力传感器8夹置于流体式弹簧6的活塞杆62顶端与第一腔体的顶壁之间,或者,如图3所示,压力传感器8也可夹置于流体式弹簧6的缸体61底端与第二腔体50的底壁之间。所述压力传感器8与压力控制装置9电连接。The pressure sensor 8 is sandwiched between the top end of the piston rod 62 of the fluid spring 6 and the top wall of the first cavity. Alternatively, as shown in Figure 3, the pressure sensor 8 can also be sandwiched between the cylinder 61 of the fluid spring 6. between the bottom end and the bottom wall of the second cavity 50 . The pressure sensor 8 is electrically connected to the pressure control device 9 .
压力控制装置9根据其接收到的压力传感器8的信号,控制缸体61内部填充物(气体或液体)的压力,进而控制流体式弹簧6输出相应的弹力(即活塞杆62抵顶上滑动套筒4第一腔体40顶壁的压力大小)。The pressure control device 9 controls the pressure of the filling (gas or liquid) inside the cylinder 61 according to the signal it receives from the pressure sensor 8, and then controls the fluid spring 6 to output the corresponding elastic force (that is, the piston rod 62 presses against the upper sliding sleeve The pressure on the top wall of the first cavity 40 of the cylinder 4).
当压力传感器8检测到压力值小于设定的压力值时,表示减震力度不足,此时压力控制装置9可控制流体式弹簧6增加弹力(如图4所示),即填充物对活塞杆62的作用力增大,活塞杆62向上伸长,上滑动套筒4与下滑动套筒5具有较长的滑动行程一,减震力度增大,从而可削减由于流体式弹簧6长时间使用后弹力减弱所带来的影响。When the pressure sensor 8 detects that the pressure value is less than the set pressure value, it indicates that the shock absorption strength is insufficient. At this time, the pressure control device 9 can control the fluid spring 6 to increase the elastic force (as shown in Figure 4), that is, the filler exerts pressure on the piston rod. The force of 62 increases, the piston rod 62 extends upward, the upper sliding sleeve 4 and the lower sliding sleeve 5 have a longer sliding stroke, and the shock absorption strength increases, thereby reducing the long-term use of the fluid spring 6 The impact of weakened back elasticity.
反之,当压力传感器8检测到压力值大于设定值时,表示流体式弹簧6弹力过大,阻尼力过大,起不到减震效果,车辆容易产生震动,此时,压力控制装置9可控制流体式弹簧6减小输出的弹力,即填充物对活塞杆61的作用力减小,活塞杆61对上滑动套筒4顶壁的作用力减小,从而保证减震效果。On the contrary, when the pressure sensor 8 detects that the pressure value is greater than the set value, it means that the elastic force of the fluid spring 6 is too large and the damping force is too large to achieve the shock absorption effect, and the vehicle is prone to vibration. At this time, the pressure control device 9 can The fluid spring 6 is controlled to reduce the output elastic force, that is, the force of the filler on the piston rod 61 is reduced, and the force of the piston rod 61 on the top wall of the upper sliding sleeve 4 is reduced, thereby ensuring the shock absorption effect.
可见,本实施例能自动量化控制减震力度,节省了车辆的维护成本以及减少了因车辆维护所带来的不便。It can be seen that this embodiment can automatically and quantitatively control the shock absorption intensity, saving vehicle maintenance costs and reducing the inconvenience caused by vehicle maintenance.
进一步的,本实施例的车辆减震***还包括路况检测装置以及处理器,于本实施例中,路况检测装置为视觉采集模块,视觉采集模块通过拍摄路面得到路况信息。在其他实施方式中,路况检测装置也可以采用加速度传感器,加速度传感器通过感应车辆当前震动时产生的加速度变化,得到路况信息,。例如,加速度变化较大时,路面为凹凸不平的路面,加速度变化较小时,路面较为平坦,即加速度变化越大,表示路面越不平坦。Furthermore, the vehicle shock absorbing system of this embodiment also includes a road condition detection device and a processor. In this embodiment, the road condition detection device is a visual acquisition module, and the visual acquisition module obtains road condition information by photographing the road surface. In other embodiments, the road condition detection device may also use an acceleration sensor. The acceleration sensor obtains road condition information by sensing acceleration changes caused by the current vibration of the vehicle. For example, when the acceleration change is large, the road surface is uneven, and when the acceleration change is small, the road surface is relatively flat, that is, the greater the acceleration change, the more uneven the road surface is.
路况检测装置将路况信息反馈给处理器,处理器内存储有多种路况数据以及与各种路况分别对应的减震方案,处理器将接收到的路况信息与其内部的路况数据进行匹配,得到实时路况,处理器调用实时路况的减震方案,发送至所述压力控制装置,压力控制装置根据减震方案控制流体式弹簧6输出相应的弹力。The road condition detection device feeds back the road condition information to the processor.
