The synergy of the above systems is a very complex process, and it is hard to say and clear that only the following is briefly mentioned in each case:

1. when the wheel meets a small pit or a depression, the vibration pressure of the wheel weight on the ground is not obvious, the elastic force of the shock-proof spring (5) of the vehicle chamber is obvious at the moment, so that the main shaft (3) of the vehicle chamber, which is connected with the shock-proof shaft (4), of the vehicle chamber presses down the non-rotating main shaft (2) or the rotating main shaft (23) of the wheel (9) through the shock-proof spring (7) on the wheel, but the elasticity of the shock-proof spring (7) on the wheel reduces the pressing stroke amplitude of the non-rotating main shaft (2) or the rotating main shaft (23), the relative vibration of the wheel on the ground is weakened, and meanwhile, the elasticity of the shock-proof spring (7) on the wheel also has a buffering effect on the vibration of the vehicle chamber and reduces the vibration amplitude of the vehicle chamber.

2. When the wheel meets a bulge, the wheel (9) forms upward pressure on the shockproof spring (7) through the non-rotating main shaft (2) or the rotating main shaft (23), the upward pressure vibration of the wheel (9) is buffered through the elasticity of the shockproof spring (7) on the wheel, more importantly, the vibration amplitude of the shockproof shaft (4) of the car room is reduced through the car room main shaft (3), and the car room is ensured to be more stable.

3. When the wheel meets a large pit and a low hole, firstly, the wheel (9) presses the lower shockproof spring (8) of the wheel under the action of the weight of the wheel, and the elasticity of the lower shockproof spring (8) enables the wheel (9) not to be violently and rapidly smashed to the ground through the non-rotating main shaft (2) or the rotating main shaft (23), so that the vibration of the wheel is reduced; secondly, the elasticity of the upper shock-proof spring (5) of the vehicle chamber enables the main shaft (3) of the vehicle chamber connected with the shock-proof shaft (4) of the vehicle chamber to press down the non-rotating main shaft (2) or the rotating main shaft (23) of the wheel (9) through the shock-proof spring (7) on the wheel, at this time, the non-rotating main shaft (2) or the rotating main shaft (23) which completes the upper shock-proof process can be upwards bounced to extrude the shock-proof spring (7) on the wheel under the combined action of the shock-proof spring (8) under the wheel and the rebound force of the ground on the wheel (9), thus the resultant force of the downward elasticity of the shock-proof spring (5) of the vehicle chamber and the rebound force of the shock-proof spring (8) under the wheel and the rebound force of the ground on the wheel (9) generates counterwork with the shock-proof spring (7) on the wheel, and as a result, the shock amplitude of the non-rotating main shaft (2) or the rotating main shaft (23) is reduced and the shock amplitude of the main shaft (3) of the wheel is reduced, i.e. both the cabin and the wheels dampen vibrations.

4. When a wheel meets a bumpy ground with continuous potholes, the device with the lever structure is a wheel shockproof system which is directly influenced greatly due to the shock speed, and a vehicle chamber shockproof system is influenced slightly, in the wheel shockproof system, a wheel shockproof shaft baffle ring (14) continuously moves up and down to respectively extrude an upper shockproof spring (7) and a lower shockproof spring (8), the elasticity of the two springs reduces the collision strength of the wheel (9) and the ground, the vibration amplitude of the wheel (9) is also reduced, meanwhile, the vehicle chamber shockproof system can greatly reduce the vibration amplitude of the wheel (9) along with the vehicle chamber shockproof system according to the lever principle, and the vibration amplitude of a main shaft (3) of the vehicle chamber is also greatly reduced due to the inertia and the lagging effect of a vehicle chamber shockproof spring (5), so that the stability of the vehicle chamber is guaranteed.

5. When the automobile turns, the action point of the wheel is considered to be outside the turning arc line of the automobile, at the moment, the inertia force of the automobile weight and the speed presses the anti-vibration spring (5) of the automobile chamber outside the arc line from top to bottom, the main shaft (3) of the automobile chamber presses the inertia force on the non-rotating main shaft (2) or the rotating main shaft (23) through the anti-vibration spring (7) on the wheel, but the vibration amplitude of the non-rotating main shaft (2) or the rotating main shaft (23) is greatly reduced due to the elasticity of the anti-vibration spring (7) on the wheel, and meanwhile, the anti-vibration spring (7) on the wheel also provides upward reverse elasticity for the main shaft (3) of the automobile chamber, so that the vibration amplitude of the automobile chamber is reduced; in the second situation, the action point of the wheel is considered to be in the turning arc of the automobile, at the moment, the inertia force of the automobile weight and the speed drives the main shaft (3) of the automobile chamber to lift from bottom to top on the shockproof spring (5) of the automobile chamber on the inner side of the arc, and in the shockproof system of the wheel, due to the weight of the wheel, the shockproof shaft baffle ring (14) of the wheel compresses the shockproof spring (8) of the wheel, the wheel (9) is prevented from being lifted or the lifting amplitude is reduced, namely the shock of the wheel is reduced.

In summary, under any condition, the novel vehicle shockproof stability-maintaining device can reduce the vibration of the wheels and keep the stability of the vehicle compartment, and is a simple, effective and novel vehicle shockproof stability-maintaining device which is not ancient.

The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the specific implementation of the present invention is not limited by the above description, and it is within the scope of the present invention to adopt various modifications of the concept and technical solution of the present invention or use the concept and technical solution of the present invention in other situations.
