a connecting rod 5 is arranged in a cavity in the shell, the rear end of the connecting rod is inserted into the air bag, the base can transmit the vibration of the automobile chassis to the air bag, after part of vibration of the air bag is eliminated, the residual vibration force is transmitted to the connecting rod, and the connecting rod is pushed to feed forwards. An oil storage cylinder 6 is also arranged in the shell, and damping oil is filled in the oil storage cylinder. The front end of the oil storage cylinder penetrates through the front end face of the shell and extends to the outside of the shell, the rear end of the oil storage cylinder extends towards the direction of the air bag, the front end of the connecting rod is inserted into the oil storage cylinder, a working cylinder 7 is inserted into the oil storage cylinder, the front end of the connecting rod extends into the working cylinder, a piston 8 is sleeved at the front end of the connecting rod and is always positioned in the working cylinder, and when the connecting rod is stressed to feed forwards, the piston can be driven to feed in the working cylinder.
The rear end cover of the oil storage cylinder is provided with a dustproof cover 9, a through hole is formed in the dustproof cover, the connecting rod is inserted into the through hole, the outer wall of the connecting rod is attached to the inner wall of the through hole, and the dustproof cover can effectively prevent external dust from entering the oil storage cylinder to pollute damping oil. Meanwhile, the outer wall of the connecting rod is attached to the inner wall of the through hole, so that damping oil can be effectively prevented from overflowing from the through hole. The connecting rod is sleeved with a guider 10, the guider is located in the oil storage cylinder, and the outer edge of the guider is fixed on the inner wall of the oil storage cylinder in a clamping mode.
The connecting rod is also sleeved with a buffer spring 11 which is connected to the piston 8 and clamped between the guider and the piston, when the connecting rod drives the piston to feed forwards, the buffer spring can be driven by the piston to be pulled up, the pulled up spring has restoring force for restoring the spring, and the restoring force can also offset part of vibration force to play part of damping effect. However, the restoring force of the buffer spring is limited, in order to enhance the damping effect, the working cylinder is divided into a front part and a rear part by the piston, the buffer spring is installed at the rear part, the front part is an air cavity, and the air pressure at the front part is increased by injecting air into the air cavity, so that the damping effect is improved by the air pressure hedging vibration force.
