Fixed board 9, wheel shaft 2 are connect by being symmetrical arranged U-shaped card hoop 10 with fixed plate 9, and cylinder barrel 3,3 middle part of cylinder barrel are fixedly installed on wheel shaft 2
Setting air-bag vibration damper 4 is slided, the air-bag vibration damper 4 is double cone bodily form air-bag vibration damper, and the 3 left and right end in inside of cylinder barrel is equal
Setting piston 5 is slided, beam 12 is fixedly installed on the side opposite with air-bag vibration damper 4 of piston 5,1 downside of Rear frame is symmetrical
Connector 6 is set, and 7 upper and lower end of pull rod is hinged with connector 6, piston 5 respectively, and block is respectively provided on the outside of 3 left and right end of cylinder barrel
8,3 middle part of cylinder barrel uniformly opens up venthole 11.
The 4 middle part outside fixed setting wearing layer 13 of air-bag vibration damper, enhances air-bag vibration damper side wall and cylinder barrel.
Shock absorbing ring 14, the collision of damper piston and block are set in the 5 outer end side surface of piston.
The operation principle of the utility model：Vibrations are transferred on pull rod by wheel shaft, and pull rod is subject from Rear frame, wheel shaft
Wait the active force that transmits of directions, pull rod pushes piston to be moved in cylinder barrel at this time, air-bag vibration damper by piston thrust
It expands or shrinks in cylinder barrel, absorb the vibration energy between wheel and Rear frame, alleviate vibrating effect, and due to not having
There are the opposite collision and friction between metal, greatly reduce vibrating noise.
The beneficial effects of the utility model are：1st, damping effect is more preferable, and the sense of jolting of car body is substantially reduced, and is substantially reduced
The noise of car body improves comfort by bus, while the service life of strong enhancing body construction.2nd, it is outer in the middle part of air-bag vibration damper
Wearing layer is fixedly installed in side, enhances air-bag vibration damper side wall and cylinder barrel.3rd, shock absorbing ring, damper piston are set in the outer end side surface of piston
With the collision of block.
Description of the drawings
