Primary clutch of motorcycle engine

Abstract

The invention provides a primary clutch of a motorcycle engine, which comprises a shell, a driving disc and a shoe block seat and is characterized by also comprising a centrifugal filter, wherein the shoe block seat is provided with a friction plate; one end of the shoe block seat is hinged with the driving disc; the centrifugal filter can be detachably assembled on the spindle of the engine; thecentrifugal filter is positioned at one side of the driving disc; a first internal spline sleeve for assembling the spindle of the engine is arranged at the middle part of the centrifugal filter; andthe driving disc and the centrifugal filter are axially fixed on the spindle of the engine through nuts. The primary clutch provided by the invention has the advantage of simple structure, the centrifugal filter can be singly disassembled to be replaced only by loosening the nut at the end side of the centrifugal filter, and the shoe block seat and the driving disc do not need to be replaced together with the centrifugal filter, thereby saving the integral service cost of the primary clutch of the motorcycle engine.

Description

technical field [0001] The invention relates to an engine clutch, in particular to a motorcycle engine primary clutch. Background technique [0002] see figure 2 The motorcycle engine primary clutch of the prior art 1 includes a housing 2 sleeved on the engine main shaft 1, a driving disc 3 and a shoe seat 5 provided with a friction plate 4. This motorcycle engine primary clutch is passed through an external The filter screen achieves filtration, so it is easy to cause clogging. see image 3 The motorcycle engine primary clutch of the prior art 2 includes a housing 2 sleeved on the engine main shaft 1, a driving disc 3, a shoe seat 5 provided with a friction plate 4, a centrifugal filter 6 and a one-way device 12, The nut 8 axially fixes the driving disc 3 on the engine main shaft 1, wherein the middle part of the centrifugal filter 6 is sheathed and fixed on the driving disc 3, and the shell 2 is sleeved on the engine main shaft 1 with gaps, and the one-way device 12 pas...

AI Technical Summary

Problems solved by technology

First of all, the service life of the centrifugal filter is usually shorter than the service life of the driving disc and the shoe seat, while the driving disc, the shoe seat and the centrifugal filter of the primary clutch of the existing motorcycle engine are fixed as one, if the centrifugal filter is to be replaced filter, the driving disc and the shoe seat must be replaced at the same time, so that the replacement of the centrifugal filter is stacked, and at the same time, the overall use cost of the primary clutch of the motorcycle engine is increased

In addition, an internal spline sleeve needs to be set between the one-way device and the driving disc, which also increases the overall cost of using the primary clutch of the motorcycle engine.
