Buffer and vibration absorption device of engine balance shaft of bestriding motorcycle

Abstract

The invention relates to a buffer and vibration absorption device of an engine balance shaft of a bestriding motorcycle. The buffer and vibration absorption device comprises a balance shaft assembly, a balance shaft driven gear and a balance shaft driven gear inner ring, and buffer mechanisms are arranged on the balance shaft driven gear and the balance shaft driven gear inner ring. The elastic contact connection of the balance shaft driven gear and the balance shaft driven gear inner ring is achieved through the buffer mechanisms, therefore, torsional pulse loads between the balance shaft driven gear and the balance shaft driven gear inner ring are reduced, impact force between the balance shaft driven gear and the balance shaft driven gear inner ring is effectively reduced, and meanwhile noise generated by the impact force is reduced. In addition, axial loads between the balance shaft driven gear and the balance shaft assembly is reduced to a certain degree through a balance shaft wave washer assembled between the balance shaft driven gear and the balance shaft assembly, noise generated by the axial loads is reduced, therefore, work impacts and abnormal sounds between engine balance shaft mechanisms are reduced, and the work stability of the balance shaft is improved.

Description

technical field [0001] The invention relates to the technical field of a balance shaft of a straddle motorcycle engine, in particular to a shock absorbing device for a balance shaft of a straddle motorcycle engine. Background technique [0002] At present, some motorcycles use engines with balance shaft devices. The balance shaft mechanism can effectively balance the reciprocating inertial force generated by the reciprocating motion of the piston, thereby reducing engine vibration, reducing engine noise, prolonging the service life of the engine and improving the comfort of the vehicle. However, the balance shaft mechanism itself works through the meshing of gears, so the impact force of the meshing of the gears will also be generated during the operation of the balance shaft, and a certain amount of meshing noise will be generated at the same time. Contents of the invention [0003] In order to overcome the problems in the prior art, the present invention provides a shoc...
