<p>A vehicular clutch mechanism in which a clutch release bearing assembly (36) centred on a transmission shaft (24) is moveable axially along the shaft to disengage the clutch (12) by an hydraulic pressure system including a master cylinder (60) operated by a clutch pedal (68) of the vehicle and a slave cylinder (62) receiving pressurised hydraulic fluid output from the master cylinder to move the release bearing assembly along the shaft to disengage the clutch and to provide coaction between a face (32a) on the release bearing assembly and a fixed surface (44a) of the housing (42) to operate a further function of the vehicle such as a clutch brake or clutch wear adjuster. Means (72) are provided which, in response to sensed increases in the hydraulic fluid pressure in the system beyond a predetermined limit, increase the volume of the hydraulic system thus minimising pressure spikes in the hydraulic pressure system initiated by the coaction between the release bearing assembly face and the housing fixed surface.</p> |
