Problems solved by technology

However, the balance shaft mechanism itself works through gear meshing, so the impact force of the gear meshing will also be generated during the operation of the balance shaft, and a certain meshing operation noise will be generated at the same time.

Embodiment Construction

[0015] The features and principles of the present invention will be described in detail below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.

[0016] Such as figure 1 As shown, the shock-absorbing device of the balance shaft of the straddle motorcycle engine includes a balance shaft assembly, a balance shaft driven gear and an inner ring of the balance shaft driven gear, and the balance shaft driven gear and the inner ring of the balance shaft driven gear A clearance fit is adopted between them, and a buffer mechanism is provided on the balance shaft driven gear and the inner ring of the balance shaft driven gear. A balance shaft wave washer is assembled between the balance shaft driven gear and the balance shaft assembly, which reduces the axial load between the two and the resulting noise to a certain extent.

[0017] Such as figure 2 As shown...

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...
