1,101,035. Clutch control; bearings. NADELLA SOC. ANON., and A. PITNER. 7 May, 1965 [14 May, 1964; 23 July, 1964], No. 19266/65. Headings F2A and F2L. A self-centring clutch release bearing comprises a roller or needle bearing D having relatively radially movable races 1, 2 and a lubricant retaining housing 8 directly contacting the ends of clutch release levers h. The bearing is pivotally mounted by bosses 54 on an actuating fork F which is pivoted to a support G by means of a ball 56 on the support engaging a socket formed in the fork. A spring 59 engages flats on a pin 57 of the support to prevent pivoting of the fork about an axis parallel to the clutch axis. As a modification, the ball 56 may be provided on the fork and the socket be formed in the support. The roller bearing may have the race 2 formed by a surface of the housing 8. In another embodiment, Fig. 12, the actuating fork is pivoted on the support by a horizontal pin and is connected to the thrust bearing by a universal joint having two perpendicular pivot axes provided by semi-cylindrical bearing surfaces 80, 81 on a ring 82 which co-operate with complementary surfaces formed on the fork and on a disc 14 which is fast with the race 1 of the bearing. |
