Abstract

Official abstract text for this publication.

A clutch for a vehicle may include a pressing member configured to interwork with a clutch pedal and move in one direction when the clutch pedal is stepped on; and an elastic member having an end portion in contact with the pressing member, and configured to apply elastic force to the pressing member in the other direction when the pressing member moves in one direction, and exert elastic force in one direction when the pressing member passes through a preset point to restrain the pressing member from being restored to its original condition.

First claim

Opening claim text (preview).

What is claimed is: 1. A clutch for a vehicle, the clutch comprising: a pressing member configured to interwork with a clutch pedal wherein the pressing member move in a first direction when the clutch pedal is stepped on; and an elastic member having a first end portion slidably in contact with the pressing member, and configured to apply a first elastic force to the pressing member in a second direction when the pressing member moves in the first direction, and exert a second elastic force in a third direction when the pressing member passes through a preset point to restrain the pressing member from being restored to an original condition thereof by itself, while pressing of the clutch pedal is released. 2. The clutch of claim 1 , wherein the pressing member is a release bearing. 3. The clutch of claim 1 , wherein the elastic member is a diaphragm spring. 4. The clutch of claim 1 , wherein an inner circumferential portion and an outer circumferential portion of the elastic member in contact with the pressing member form an initial slope, wherein the initial slope is set such that the elastic force apply to the pressing member in the second direction. 5. The clutch of claim 1 , wherein the pressing member includes a groove formed along a longitudinal direction of the pressing member, wherein the first end portion of the elastic member selectively slides in the groove of the pressing member and a second end portion of the elastic member is coupled to a housing, and wherein a supporting portion is positioned between the first and second end portions of the elastic member and configured to engage a portion of the elastic member to the housing.
