Technical problem to be solved in the utility model is: it is stable, comfortable, simple in structure to provide a kind of vehicle to exercise, and vibrates little automobile-use rear linkage.
The technical scheme that its technical matters that solves the utility model adopts is: comprise the rear-axle differential assembly, its constructional feature is to be connected with quadra on described rear-axle differential assembly, quadra is provided with spring mounting seat with the rear portion of two frames that the axle tube of rear-axle differential assembly is connected, be provided with the damper spring that is connected to main car frame in the spring mounting seat, front portion corresponding to spring mounting seat on described two frames is provided with the buffering Connection Block, and buffering is provided with shock absorber in the Connection Block: the middle part of back frame that is parallel to the axle tube of rear-axle differential assembly at quadra is provided with the damper spring of pulling back that is connected to main car frame.
Be provided with the rear-mounted engine mounting bracket in the front portion of described quadra, this rear-mounted engine places the bottom of quadra with mounting bracket, and rear-mounted engine is provided with cushion collar with the junction of mounting bracket and quadra.
On described rear-axle differential assembly, be provided with and be connected to the universal buffer driving device of driving engine on the power take-off shaft after the speed change.
Described shock absorber comprises a barrel shrond, the buffering gum cover that is set with two hollows of symmetry in the inner chamber of barrel shrond, and the axial end portion of described barrel shrond docks with the flange of buffering gum cover.
After adopting said structure, because the anterior rigidity of this automobile-use rear linkage is connected on the main car frame, its rear portion is connected with main car frame by damper spring, therefore connects firm, vehicle is exercised stable, comfortable, and simple in structure, vibrate for a short time, noise is low, the service life of damper spring is than the long service life of spring plate, the angle of inclination was little when vehicle turned round, the vehicle frame left and right sides amplitude of oscillation is little when moving, even there is a damper spring can not use because of reasons such as fractures, vehicle still can move.
