Abstract

The invention provides a vehicle shock absorber and a vehicle. The vehicle shock absorber comprises a flywheel mass, two disc hub flanges and a plurality of damping springs, wherein the two disc hub flanges and the damping springs are arranged between two side plates. One disc hub flange is in transmission connection with an engine crankshaft, and the other disc hub flange is in transmission connection with an input shaft of a transmission. The first damping spring in the multiple damping springs only corresponds to the first disc hub flange, and the second damping spring in the multiple damping springs only corresponds to the second disc hub flange, so that the first damping spring and the second damping spring are connected in series in the torque transmission process of the shock absorber, and accordingly, the total relative rotation angle of the two disc hub flanges is equal to the sum of the relative rotation angle of the first disc hub flange relative to the side plates and the relative rotation angle of the side plates relative to the second disc hub flange. Thus, compared with an existing dual-mass flywheel, the vehicle shock absorber is simple in structure and low in cost,torsional rigidity can be effectively reduced, and therefore the vehicle shock absorber has an excellent shock absorption effect.

Description

technical field [0001] The present invention relates to a shock absorber for a vehicle and a vehicle including the same. Background technique [0002] In the prior art, the dual-mass flywheel is usually installed between the engine crankshaft of the vehicle and the input shaft of the transmission, and is used to transmit the torque of the engine crankshaft to the input of the transmission while effectively attenuating the torsional vibration of the engine crankshaft. Shaft, thereby reducing the impact of torsional vibration of the engine crankshaft on the transmission. In addition, generally a disc damper with a single flywheel mass and two side plates formed by stamping has a similar damping effect to a dual-mass flywheel and is simpler in structure and lower in cost than a dual-mass flywheel. However, compared with the dual-mass flywheel, the torsional rigidity of the existing disc damper is relatively high, which will reduce the damping effect of the disc damper. Conte...
