Supporting structure for supporting separation bearing

Abstract

The invention provides a support structure for supporting a separate bearing in a clutch device that processes or interrupts power transmission from a driving shaft to a driven shaft. The support structure includes: a diaphragm spring that is provided with an inner circumference part, the inner part is formed with a symmetric shape relative to an axis center of the driven shaft, the diaphragm is combined with the driving shaft; the separate bearing that is provided with an inner ring through an outside circumference of the driven shaft with a given radial clearance, the separate bearing is provided with an outside ring and an annular butt jointing part of one end of the inner ring with a method for line contacting to the inner circumference part of the diaphragm spring; and a separate fork that can push the outside ring of the separate bearing; wherein, the separate bearing is shift along axial direction of the driven shaft through vibrating the separate fork by the clutch device, consequently the diaphragm spring is converted for processing or interrupting power transmission from the driving shaft to the driven shaft.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2007-058128 filed on March 8, 2007, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a support structure for supporting a release bearing in a clutch device, and more particularly, to a support structure for supporting a release bearing for urging a diaphragm spring for a release clutch. Background technique [0004] Conventionally, as shown in Patent Document 1, a dry type single-plate clutch for a manual transmission is known. In this known dry single-plate clutch, the aligned release bearing is supported on a cylindrical bearing carrier integrally formed on the front cover, which is part of the transmission housing. That is, a spring is interposed between the outer ring of the release bearing and the cover, and a release hub made of synthetic resin is slidably arranged on...

AI Technical Summary

Problems solved by technology

[0007] According to this structure of Patent Document 2, although it is not necessary to provide a bearing support on the front cover, since the release hub is arranged on the inner diameter side of the release bearing, the radial dimension cannot be greatly reduced.

Moreover, since the release hub slides on the rotating driven shaft, the wear of the release hub is further increased compared with the case where the release hub slides on the bearing support, and due to the frictional resistance between the driven shaft and the release hub increased clutch operating force

And worsened the operating feeling
