Embodiment Construction

[0013] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0014] A clutch device 1 used in a vehicle is placed in a clutch housing 2 . The clutch disc 5 is supported by being sandwiched between the flywheel 3 and the pressure plate 4 . The peripheral edge portion of the diaphragm spring 6 bears against said pressure plate 4 . Also, the sleeve 10 is arranged in the clutch housing 2 and adjoins the release bearing 7 . One end face 12 of the piston 11 displaceable in the axial direction of the sleeve 10 bears against said release bearing 7 . The pipe 13 fixed on the clutch housing 2 communicates with the fluid chamber 14 of the sleeve 10 , so that the pressure of the clutch working fluid in the fluid chamber 14 acts on the other end surface 15 of the piston 11 .

[0015] In addition, a folded protective cover 16 covering the sleeve 10 is installed so as to protect the sleeve 10 from dust in the...

Abstract

In a clutch apparatus being accommodated in the clutch housing, the piston of the sleeve cylinder is brought into contact with a release bearing in contact with a diaphragm spring for performing the disconnecting operation of the clutch disk, a switch actuation section is disposed to face opposite from the side of the clutch housing to an arm section of the release bearing, the arm section drives the switch actuation section accompanied by axial displacement in the release bearing when the clutching disk reaches the limit of wear, and an alarm device outside the clutch housing is actuated.

Description

technical field [0001] The invention relates to a device for detecting clutch disc wear in a vehicle. Background technique [0002] Heretofore, there has been provided a structure that performs a clutch release operation by pushing the release bearing in its axial direction by a sleeve cylinder provided in a clutch housing, thereby eliminating the need for a clutch manipulation link mechanism. In this case, the sleeve for performing the clutch disengagement operation is provided in the clutch case, and only one pipe for supplying and discharging the clutch working fluid is provided outside the clutch case. It is therefore difficult in practice to detect whether the clutch disc has reached its wear limit. Contents of the invention [0003] The present invention is designed in view of the above-mentioned disadvantages. Therefore, it is an object of the present invention to facilitate the detection of whether the clutch disc has reached the wear limit even when the clutch r...
