Title: A friction clutch for a vehicle.
IPC: F16D23/14
Filed: 1985-02-20
Abstract: A detent (25) is rotatably mounted between a hollow shaft (24) and a hub (26) of a clutch release mechanism (20), to locate the shaft and hub. In an operative position of the detent, a clutch release force can be transmitted from the shaft to the hub. - When the shaft is urged in one direction w.r.t. the hub, the detent is rotated by a release ring into a release position. In the latter position, separation of the shaft and hub is allowed. Pref. the hub has a formation against which the detent rotates. The formation and detent have engageable curved bearing surfaces. (2/11) GBAB- GB2155139 B A friction clutch for a vehicle which includes a clutch release mechanism comprising a first member, a clutch release bearing axially fast with said first member, a second member, a detent means arranged to locate the first member relative to the second member by moving the first member in one direction relative to the second member whereby a clutch release force subsequently applied to said first member through said clutch release bearing in an opposite direction will be transmitted to said second member to release the clutch and detent release means which enables the detent means to be released by urging said first member further in said one direction relative to said second member so that the first and second members can thereafter be separated, said detent means being positioned rotatably between the two members, whereby said detent means in an operative position permits said clutch release force to be transmitted from said first member to said second member and which on urging said first member further in said one direction the entire detent means is rotated relative to said members by said release means into a release position which permits separation of said first and second members. - GB2155139 B A friction clutch for a vehicle which includes a clutch release mechanism comprising a first member, a clutch release bearing axially fast with said first member, a second member, a detent means arranged to locate the first member relative to the second member by moving the first member in one direction relative to the second member whereby a clutch release force subsequently applied to said first member through said clutch release bearing in an opposite direction will be transmitted to said second member to release the clutch and detent release means which enables the detent means to be released by urging said first member further in said one direction relative to said second member so that the first and second members can thereafter be separated, said detent means being positioned rotatably between the two members, whereby said detent means in an operative position permits said clutch release force to be transmitted from said first member to said second member and which on urging said first member further in said one direction the entire detent means is rotated relative to said members by said release means into a release position which permits separation of said first and second members. USAB- US4646897 A The clutch comprises a clutch plate which can be retracted by a release mechanism to release a driven plate. The release mechanism comprises two second members (24,26) and an intermediate detent (25). The detent is rotatably mounted on member (24). - The detent is located between the members in an operative position by urging the first member in one direction relative to the second member. To separate the members, the first member is urged further in the one direction to enable a detent release ring (37) to rotate the detent into a release position.
