Abstract

1483860 Friction clutches VSES NI INST STROITEL I DOROZH MASHINOST 13 March 1975 10411/75 Heading F2C In a multi-plate friction clutch for a motor vehicle wherein a clutch engaging servo piston 2 is biased by a spring 9 to a clutch disengaged position and is moved left by pressure liquid to apply a clutch engaging force through springs 8 and a presser plate 7 to clutch plates 5, 6 a valve plug 3 is moved axially in bores adjacent the periphery of the piston 2 by contact with the presser plate 7 or a housing 1 to cushion clutch engagement by modulating the pressure buildup in the servo chamber and to facilitate rapid clutch disengagement by exhausting liquid from the servo chamber. With the clutch disengaged, as shown, the plug 3 closes the bores in the servo piston so that when pressure liquid is supplied through ducts 12 to the servo chamber the piston 2 and presser plate 7 move rapidly left until light clutch engagement is obtained. Thereafter, as pressure builds-up in the servo chamber, the springs 8 permit relative axial movement between the servo piston 2 and presser plate 7 and the plugs 3, which abut the presser plate 7, are moved right relative to the servo piston 2 to open the bores and thus provide a slow pressure build-up in the servo chamber. When the clutch is fully engaged the servo piston 2 abuts the presser plate 7 which closes the bores to provide maximum clutch engaging servo pressure. To disengage the clutch the pressure liquid supply to the servo chamber is cut off and the springs 8, 9 move the servo piston 2 away from the presser plate 7 to permit rapid exhaust of the servo chamber through the bores. When the clutch is fully disengaged the plugs 3 abut the housing 1 and are moved left relative to the servo piston to close the bores and prepare the clutch for re-engagement. One of the plugs 3 may have a small passage therethrough to exhaust any residual liquid in the servo chamber.
