Title:
VEHICLE SHOCK ABSORBER AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/217515
Kind Code:
A1
Abstract:
Disclosed is a vehicle shock absorber, which has an axial direction (A), a radial direction (R), and a circumferential direction, and is configured for transmitting torque from a power source of a vehicle to a transmission of the vehicle via the vehicle shock absorber. The torque transmitted via the vehicle shock absorber is not greater than a predetermined torque capacity limited by the vehicle shock absorber, and the vehicle shock absorber is configured for attenuating torsional vibration of the transmitted torque. The vehicle shock absorber comprises: three side plates, which are fixed to one another; a flange (4) capable of rotating within a predetermined range in the circumferential direction and with respect to the three side plates; a plurality of damper springs (5); a centrifugal pendulum unit (6); and a torque limiting mechanism (7). The flange (4) can transmit the torque to the three side plates via the plurality of damper springs (5), and the centrifugal pendulum unit (6) is arranged between a first side plate (31) and a second side plate (32) of the three side plates or between the second side plate (32) and a third side plate (33) of the three side plates. The torque limiting mechanism (7) is arranged between the second side plate (32) and the third side plate (33) and is used for limiting the predetermined torque capacity. Further provided is a vehicle comprising the vehicle shock absorber. By using the shock absorber, vibration in a torque transmission process can be effectively weakened or even eliminated during the process of torque being transmitted by the vehicle shock absorber, and therefore, the transmission of excessive torque from a power source to a transmission of a vehicle can be prevented, and torque overload is thus avoided.
