A gearbox shock absorber

Abstract

The invention relates to a transmission shock absorber which comprises an input motor rotor, an input disc and an input flange. The motor rotor is connected with the input disc. The input flange is connected to an input flange cover through a bolt connecting piece and connected with an input gear through a connecting device. A connecting disc in the connecting device is communicated with the inner center of the input flange. The two ends of the connecting disc are in contact with the inner wall of the input gear and the connecting disc is connected and fixed through a bolt penetrating through the inner center of the whole input flange. The input disc and the input flange cover are connected through a damping spring device. An elastic piece is arranged at the step end of the input disc in a sleeved mode and fixed to the input disc through a connecting piece. The elastic end of the elastic piece is pressed on the damping spring device. The transmission shock absorber has the advantages that the input disc and the input flange cover are elastically connected, so that large rotational inertia of the motor rotor is isolated and gear shift impact is reduced; meanwhile, parameters of the shock absorber are dynamically simulated through a transmission system, actually-collected data are substituted to conduct optimal computation, so that the effect is remarkable, noise of a motor and vibration caused by a transmission are reduced, a transmission shell is not damaged, and therefore the gear shifting quality and the automobile driving performance are improved.

Description

technical field [0001] The invention relates to a gearbox shock absorber, in particular to a gearbox shock absorber used on a pure electric bus. Background technique [0002] At present, pure electric buses are generally used in urban buses. Due to the huge moment of inertia of the motor rotor, the gearbox in the pure electric bus has obvious vibration, obvious shifting impact, and unsatisfactory noise. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a gearbox shock absorber which can solve the vibration generated during the operation of the gearbox, reduce the shock of shifting and reduce the noise. [0004] The object of the present invention is accomplished through the following technical scheme, which includes an input motor rotor, an input flange cover, an input disc, an input gear and an input flange, the motor rotor is connected to the input disc, and the input flange is connected ...
