技术领域 technical field

背景技术 Background technique
空气悬架的主要功能是保持车架和车桥之间的距离基本不变，可以使车辆获得良好的平顺性，从而实现对货物和道路的有效保护。传统车辆的空气弹簧悬架系统主要有弹簧、减震器、导向机构组成，其刚度根据空气弹簧高度的变化而变化，较小范围内的高度变化对高度的影响不大，而高度变化会改变车辆悬架偏频，破坏车辆的操纵稳定性。减震器则通常采用固定机构，只能保证其设计时所确定的阻尼系数。这些特性影响车辆的形式性能和操作的稳定性，使乘坐舒适性和操作稳定性无法得到满足，只能保证车辆在某一特定的道路和速度条件下达到性能折中，被动的承受地面对车身的作用力，而不能主动控制悬架的特性以适应外来激励。为了克服悬架特性对车身性能的限制，国外发达国家的高档客车均采用了电子控制空气悬架系统，并对空气弹簧和减振器的结构进行一些改进，以满足车辆的减振要求。国内也做了大量的研究，但目前产品多用于高档的越野车上，对于用于运输的轻型货车，研究的相对的就更少。 The main function of the air suspension is to keep the distance between the frame and the axle basically unchanged, so that the vehicle can obtain good ride comfort, thereby achieving effective protection of goods and roads. The air spring suspension system of traditional vehicles is mainly composed of springs, shock absorbers, and guide mechanisms. The suspension frequency of the vehicle will destroy the handling stability of the vehicle. The shock absorber usually adopts a fixed mechanism, which can only guarantee the damping coefficient determined during its design. These characteristics affect the form performance and operational stability of the vehicle, so that the ride comfort and operational stability cannot be satisfied. The force of the body, but cannot actively control the characteristics of the suspension to adapt to the external stimulus. In order to overcome the limitations of the suspension characteristics on the performance of the vehicle body, high-end passenger cars in developed countries have adopted electronically controlled air suspension systems, and some improvements have been made to the structure of the air springs and shock absorbers to meet the vehicle's vibration reduction requirements. A lot of research has also been done in China, but currently the products are mostly used on high-end off-road vehicles, and relatively less research has been done on light trucks for transportation.

The air outlet of the first two-position two-way solenoid valve 1 is connected to the air spring 7 on one side of the rear suspension of the light truck, and the air outlet of the second two-position two-way solenoid valve 2 is connected to the air spring 7 on the other side of the rear suspension of the light truck A pressure sensor 5 is connected between the air spring 7, the air reservoir 4 and the two-position three-way solenoid valve 3; the pressure sensor 5 and the displacement sensor 8 used to measure the height of the air springs on both sides of the rear suspension are respectively connected to the processor The input end of 6, the first two-position two-way solenoid valve 1, the second two-position two-way solenoid valve 2, and the two-position three-way solenoid valve 3 are respectively connected to the output end of the processor 6.

本实用新型的工作原理是： The working principle of the utility model is:
1）根据路况，通过遥控器10选择对应路面等级的按钮15。 1) According to the road condition, select the button 15 corresponding to the road surface grade through the remote controller 10 .
2）采用处理器6的内部逻辑运算，在车辆启动但速度为零的情况下，按下遥控器10上的复位按钮13，执行短时间的充气和放气，而后恢复至对应路况车辆正常行驶的初始高度，目的是测量获得车辆充气高度增加量和排气高度减少量的时间。在车辆行驶过程中，带入上述测量时间和车辆的当前高度及初始高度，进行计算，得出车辆所需的充气或放气时间。 2) Using the internal logic operation of the processor 6, when the vehicle starts but the speed is zero, press the reset button 13 on the remote control 10 to perform a short-term inflation and deflation, and then return to the normal driving of the vehicle corresponding to the road condition The purpose of the initial height is to measure the time to obtain the increase in the vehicle's inflated height and the decrease in the exhausted height. During the driving process of the vehicle, the above measurement time, the current height and the initial height of the vehicle are used for calculation, and the required inflation or deflation time of the vehicle is obtained.
3）处理器6内部设置有高度区间，当位移传感器8检测到空气弹簧7高度计算的差值超出这一区间时，处理器6控制第一两位两通电磁阀1、第二两位两通电磁阀2、两位三通电磁阀3动作，储气筒4向两个空气弹簧7充放气，从而避免电磁阀频繁动作。 3) The processor 6 is provided with a height interval. When the displacement sensor 8 detects that the calculated height difference of the air spring 7 exceeds this interval, the processor 6 controls the first two-position two-way solenoid valve 1 and the second two-position two-way solenoid valve 1. The solenoid valve 2 and the two-position three-way solenoid valve 3 act, and the air reservoir 4 charges and deflates the two air springs 7, thereby avoiding the frequent action of the solenoid valve.
4）处理器6根据计算的充排气的时间控制第一两位两通电磁阀1、第二两位两通电磁阀2、两位三通电磁阀3的动作时间。当一次充气和排气过程结束后，重新判断，重新计算，重新获得车辆所需的充气或放气时间。 4) The processor 6 controls the action time of the first two-position two-way solenoid valve 1 , the second two-position two-way solenoid valve 2 and the two-position three-way solenoid valve 3 according to the calculated filling and exhausting time. After one inflation and exhaust process is over, judge again, recalculate, and regain the required inflation or deflation time of the vehicle.
5）在车辆装卸货物时，可选择遥控器10的上升、下降按钮11、12，可以在工作范围内随意设定，以便货物装卸。 5) When the vehicle is loading and unloading goods, the up and down buttons 11 and 12 of the remote controller 10 can be selected, which can be set arbitrarily within the working range to facilitate the loading and unloading of goods.
6）储气筒4和两位三通电磁阀3之间连接有压力传感器5，主要监测储气筒4的内部压力，当储气筒4的内部压力低于动作允许值，系统报警，处理器6即会指示当前故障状态。 6) There is a pressure sensor 5 connected between the gas storage tank 4 and the two-position three-way solenoid valve 3, which mainly monitors the internal pressure of the gas storage tank 4. When the internal pressure of the gas storage tank 4 is lower than the action allowable value, the system alarms, and the processor 6 immediately will indicate the current fault status.
