A device for securing a unit in a housing, in particular for securing a fixed bearing of a pinion in a steering gear of a motor vehicle, comprises a securing element which is inserted into a bore in the housing. The securing element is provided with at least one latching lever, wherein the at least one latching lever latches into toothing gaps of a toothing geometry in the bore of the housing via a latching lug disposed at the free end of the latching lever, or wherein at least one latching lug is disposed in the bore, which latches into toothing gaps of a toothing geometry in the securing element.

Device for the positional securing of a unit

A continuously variable transmission wherein each of two parallel shafts carries a pulley having a fixed flange and a second flange movable axially of the shaft toward and away from the respective fixed flange. An endless torque transmitting chain or belt is trained over the two pulleys. At least one flange of at least one of the pulleys is assembled of two or more parts which consist of sheet metal and are welded and/or otherwise affixed to each other.

Transmission

A continuously variable transmission with two adjustable pulleys and an endless torque-transmitting chain trained over the pulleys has a torque sensor which transmits variable torque from the rotary output element of a prime mover (such as the engine of a motor vehicle) to the axially movable flange of one of the pulleys. The torque sensor comprises one or more rolling elements and cam faces and/or guide surfaces which confine the rolling element(s) to movements radially and/or axially of the respective pulley. At least the rolling element(s) and those components of the torque sensor which define the cam faces and/or the guide surfaces of the torque sensor are confined in a fluid-containing plenum chamber adjacent the axially movable flange of the one pulley to thus achieve a pronounced reduction of space requirements of the unit including the one pulley and the torque sensor in the axial direction of the one pulley. The fluid in the plenum chamber serves to urge the axially movable flange of the one pulley against the adjacent edge face of the chain and to thus urge the other edge face of the chain against the axially fixed flange of the one pulley.
