Abstract

Abstract A clutch release bearing having an outer cap provided with at least one extending lug is connected to a clutch release actuating element by a flat spring having a planar shank at one end adapted to be connected to the lug and a planar shank at the other end adapted to be articulatingly connected to the actuating element. The spring is bent between the end shanks in an unstressed condition wherein the shanks lie at an acute angle to each other. During assembly the spring is further bent so that its shanks lie substantially over one another and the spring is in stressed condition.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 185 words
In a clutch release bearing having an outer cap provided with at least one extending lug adapted to engage a clutch release actuating element comprising a hook-like end having a curved outer edge and a slot opening along an inner edge, a connecting element comprising a flat spring member having a shank at one end adapted to be connected to said lug and a shank at the other end having a planar surface forming a rest plate for slidably engaging said curved outer edge, said spring being bent between said end shanks in an unstressed condition wherein said shanks lie at an acute angle to each other and which may thereafter be bent so that said shanks substantially overlie each other when connected to said lug and when slidingly engaging said clutch release actuating element so as to be in stressed condition, said spring being further formed with a perpendicular wall integral with said planar surface forming said rest plate along one side thereof and a web extending from said wall at right angles thereto overlying said planar surface and slidingly engaging within said slot.
Claim 2
Dependent Claim 185 words
In a clutch release bearing having an outer cap provided with at least one extending lug adapted to engage a clutch release actuating element comprising a hook-like end having a curved outer edge and a slot opening along an inner edge, a connecting element comprising a flat spring member having a shank at one end adapted to be connected to said lug and a shank at the other end having a planar surface forming a rest plate for slidably engaging said curved outer edge, said spring being bent between said end shanks in an unstressed condition wherein said shanks lie at an acute angle to each other and which may thereafter be bent so that said shanks substantially overlie each other when connected to said lug and when slidingly engaging said clutch release actuating element so as to be in stressed condition, said spring being further formed with a perpendicular wall integral with said planar surface forming said rest plate along one side thereof and a web extending from said wall at right angles thereto overlying said planar surface and slidingly engaging within said slot.
Claim 3
Dependent Claim 29 words
The apparatus according to claim 1, wherein said shank end connected with said lug is bent along its sides to form a U-shaped retaining member engageable about said lug.
Claim 4
Dependent Claim 21 words
The apparatus according to claim 2, wherein the sides of said U-shaped retaining member are bent slightly inwardly at one end.
