Board is connected, and described longitudinal tie is connected with vehicle bridge upper backup pad.
Further, described longitudinal tie is distributed in suspension both sides in splayed configuration, and described hydro-pneumatic spring is in splayed configuration
It is distributed in suspension both sides.
In order to ensure that front suspension has certain free degree, front-wheel and ground good contact are kept, there is provided good traction
Power, while vibration can be effectively absorbed, the V-type frame opening left and right ends portion passes through rubber shaft bearing and vehicle bridge lower supporting plate respectively
Connection, V-type frame head is connected with the pin hole seat being arranged in front frame by oscillating bearing.
Further, described hydro-pneumatic spring both ends are respectively equipped with mounting hole, and oscillating bearing is provided with described mounting hole,
Described hydro-pneumatic spring is connected by described oscillating bearing with the upper backup pad of described vehicle frame and the vehicle bridge, hydro-pneumatic spring
With good non-linear rigidity and shock absorption, the eigentone of reduction.
Further, described longitudinal tie is connected with described vehicle bridge upper backup pad by oscillating bearing, and described is vertical
It is connected to pull bar by described rubber shaft bearing with described vehicle frame, longitudinal tie rear end is reserved by rubber shaft bearing and vehicle frame
Pin hole seat connects, and while ensureing that suspension has the suitable free degree, there is rubber shaft bearing certain damping characteristic effectively to buffer
Partial vibration impacts, and improves the union piece life-span.
Beneficial effect caused by the utility model：The utility model suspended structure reduces unsprung mass, improves
Space availability ratio, cost is reduced, improve ride performance and comfortableness, and most of part in the utility model is axle
Hold or pin connects, can conveniently dismantle.
