Abstract

The invention discloses a torsion shock absorption device, a flywheel and a car transmission system, and belongs to the technical field of shock absorption. The torsion shock absorption device comprises a first shock absorber and a second shock absorber. The first shock absorber comprises a first shock absorption disc, a first elastic part and a first shock absorption disc hub, and the first shockabsorption disc is connected with the first shock absorption disc hub through the first elastic part. The second shock absorber comprises a second shock absorption disc, a second elastic part and a second shock absorption disc hub, the second shock absorption disc is connected with the second shock absorption disc hub through the second elastic part, and the second shock absorption disc is fixedly connected with the first shock absorption disc hub. The flywheel comprises the torsion shock absorption device. The car transmission system comprises the flywheel. The torsion shock absorption device has the characteristics of being large in torsion angle and good in shock absorption effect. The flywheel can effectively reduce vibration generated by transmission between an engine output shaft and a transmission input shaft. The car transmission system can effectively avoid abnormal vibration of a car body and improve the smoothness and comfort during acceleration of a car.

Description

Technical field [0001] The invention relates to the technical field of vibration reduction, and in particular to a torsional vibration reduction device, a flywheel and an automobile transmission system. Background technique [0002] Since the car's engine obtains energy through deflagration, its torque output will have torque fluctuations. The fluctuation frequency varies with the engine speed, which is the engine's excitation frequency. On the other hand, the transmission system of a general automobile cannot completely avoid the excitation frequency of the engine due to its high system rigidity. Based on the above situation, system resonance is prone to occur during torque transmission, resulting in abnormal vibration of the automobile’s powertrain, body and other systems. It will adversely affect the ride comfort and comfort of the vehicle. The solution is to reduce the resonance frequency of system torque transmission and avoid the excitation frequency of the engine. In the...
