该中减振作用失效装置的工作原理：在初始状态时，底部基件2与汽车轮轴1处于分离状态，两者互不接触，推杆316的顶端连接到汽车车身底板上，这个过程汽车的减振装置是有效的。当需要减振装置失效的时候，液压缸装置31的推杆316在液压作用下推出液压腔311，由于推杆316的顶端已经固定在汽车底板上，上部基件3连通底部基件2则被向下推动，同时固定设置在上部基件3上的侧部支撑件5和铰接在侧部支撑件5上的夹爪6同时向下移动，当推动一定距离后，底部基件2底部的弧面将扣合到汽车轮轴1上，底部基件2将不再向下移动；这时，上部基件3将会向下压紧压缩弹簧4，夹爪6在向下移动的过程中左右两侧的夹爪6将收缩并在某一时刻夹紧汽车轮轴1并将汽车轮轴1锁定，至此，汽车的减振装置将失效。当液压缸装置31不在工作后，推杆316收缩进到液压腔311中，在压缩弹簧4的作用下，整个失效装置又可以恢复到初始状态，汽车的减振装置恢复到有效状态。The working principle of the damping action failure device is: in the initial state, the bottom base member 2 is separated from the vehicle axle 1 and the two are not in contact with each other, and the top end of the push rod 316 is connected to the vehicle body floor. The vibration damping device is effective. When the vibration damping device is required to be failed, the push rod 316 of the hydraulic cylinder device 31 pushes out the hydraulic pressure chamber 311 under the action of the hydraulic pressure. Since the top end of the push rod 316 is fixed on the bottom plate of the automobile, the upper base member 3 is connected to the bottom base member 2 Pushing downward, while the side support 5 fixedly disposed on the upper base member 3 and the jaw 6 hinged on the side support member 5 are simultaneously moved downward, and after pushing a certain distance, the arc at the bottom of the bottom base member 2 The surface will be snapped onto the car axle 1, and the bottom base member 2 will no longer move downward; at this time, the upper base member 3 will press down the compression spring 4, and the jaws 6 will move left and right during the downward movement. The side jaws 6 will contract and clamp the car axle 1 at a certain moment and lock the car axle 1 so that the vehicle's damping device will fail. When the hydraulic cylinder device 31 is not in operation, the push rod 316 is retracted into the hydraulic chamber 311, and under the action of the compression spring 4, the entire disabling device can be restored to the initial state, and the vibration damping device of the automobile is restored to an effective state.
