Abstract

1389334 Clutch/brake combinations; fullface disc brakes SKF (UK) Ltd 24 May 1973 [26 May 1972 15 June 1972] 25027/72 and 28103/72 Headings F2C and F2E Fluid pressure disengagement of a clutch having operating members 3 and engagement thereafter of a brake 5, 6 to retard the clutch output shaft 1 is effected by a slave piston comprising a shoulder 10 on a sleeve 9 and slidable in a slave cylinder 7 when fluid under pressure is supplied from a master cylinder through a union 11 and passages 13 and 19 to the cylinder to move the sleeve 9 to the right and disengage the clutch through a release bearing 24 and a flange 26 of a sleeve 25, the brake being actuated when the sleeve 9, which moves a sleeve 21 to the right, moves sufficiently to take up lost motion 38 so that sleeve 21 moves a presser plate 35 to press the brake disc 6 against a fixed surface 5. The sleeves 9 and 21 are biased (in the embodiment illustrated) by a spring 31 which acts between a sleeve 27 secured to sleeve 9 and the sleeve 21 to bias the former to the right into engagement with levers 3, and the latter to the left. Also between the sleeves 9 and 21 is a chamber 16 which compensates for wear of the clutch to maintain constant the lost motion 38. An inlet to the chamber 16 is provided with a valve comprising a ball 17 sprung to the open position by a spring 18. On supply of fluid to disengage the clutch the pressure closes this valve to trap fluid in chamber 16 and so allow sleeve 21 to be moved by the sleeve 9 via this chamber but on re-engagement the valve may open to allow fluid to enter chamber 16 if it increases in size due to clutch wear (which moves sleeve 9 to the left). The presser plate 35 is held in contact with a flange 8 by springs 36. In an alternative embodiment the spring 31 is replaced by a spring which only biases the brake operating sleeve (62) to the left against a circlip (53), (Fig. 2, not shown). In this embodiment the fluid supply to the wear compensating chamber is separate from that from the master cylinder and a simple check valve controls its ingress. In a further embodiment (Fig. 3, not shown) the movement to the left of the brake operating sleeve is limited by a circlip on the sleeve engaging a flange fixed to the cylinder rather than by a circlip of the cylinder such as clip 34 shown. The invention is for use in a motor vehicle, the shaft 1 being the input shaft of a gear-box. 4
