A clutch device is described comprising a first clutch element, a second clutch element that is disposed in a coaxial manner in relation to the first clutch element, a first engagement means, a second engagement provided for engaging with the first engagement in a positively interlocking manner for transmitting a torque between the first clutch element and the second clutch element, and a spring biasing the first engagement element and the second engagement element in a circumferential direction against each other. The spring comprises a leg spring with a ring part and two legs, wherein the ring part is disposed in a substantially coaxial relation to the first and second clutch parts and the legs extend in a radially outward direction.

Clutch assembly with a leg spring

A continually variable cone-pulley, belt-drive transmission includes a primary shaft having a cone-pulley arrangement actuated by a pressure servo, a secondary shaft driven by an endless belt having a cone-pulley, actuated by a second pressure servo. Spring assemblies located in the pressure servo preload compression springs. Each spring assembly includes a compression spring located in spring-receiving rings, a cup-shaped support ring, and a guide ring comprising a peg-shaped spring guide. Preload on the compression springs is released during the first complete movement of the cone-pulley assembly by loading a locking and unlocking pin.

Device for setting a gear ratio in a continually variable belt-drive

A control valve arrangement for a continually variable transmission includes a first valve for regulating pressure in a primary servo for the gear ratio of the transmission and a second valve for regulating pressure in a secondary servo controlling tension of the drivebelt. These valves are acted upon by a throttle shaft as a function of output torque of the engine. A modulating device varies pressure in the secondary servo as a function of the gear ratio and of engine torque. The modulating device comprises a lever having one end acted upon by a cam disk as a function of the engine torque and second end acted upon by a valve element of the second regulating valve. The second lever is extended radially outward from a pivot. A sensor arm acts as a function of the gear ratio on one end of the second lever, whose other end is rotatably pinned to the first lever.
