A cone pulley transmission is disclosed which includes an infinitely actuatable and adjustable transmission wherein an axially displaceable cone pulley disc is adjustable by application of hydraulic tensioning so as to generate the pressure forces acting on a transmission belt rotating between the cone pulley discs, with the tensioning being controlled by a pressure medium through a sliding control valve. The tensioning is provided by different sized pressure chargeable surfaces and is throttled to different degrees with respect to the associated outlet of the sliding control valve. In this connection, it is provided that at least one outlet can be changed as a function of certain parameters.

Infinitely variable cone pulley transmission

An infinitely variable cone disc transmission is disclosed in which the contact pressure forces are generated fully hydraulically and in which the contact pressure level is set either solely by way of a torque sensor that is disposed on the drive shaft and constitutes a pressure medium throttle that is adjustable as a function of the load, or in which a pressurizing valve preceding this torque sensor and controlled as a function of the transmission ratio is employed to additionally effect throttling as a function of the transmission ratio.

Cone disc transmission, particularly for motor vehicles

The link chain is formed of elongated links (2) connected transversely by connecting joints (4) which are formed by pairs of connecting joint elements (1). The connecting joint elements, in cross section, are somewhat crescent-shaped or bent, oval, and define joint engagement surfaces in the region of the terminal ends, for engagement with link engagement surfaces formed in apertures (5) of the link elements (2). The convex side of an inner link element (1) of the pair fits against the concave side of an outer link element of the pair, which, in turn, bears with its joint engagement against the link engagement surface of the aperture. The arrangement permits constructing all the link elements in identical manner, and, further, by placing the joint element pairs in respective link elements with the outermost ones of the link elements engaging, selectively, the link engagement surfaces either with the respective joint engagement surface on the concave side or on the convex side, permits placement of the roll-off of the link elements with respect to each other at different locations with respect to a median or center line, thereby substantially reducing noise level of the chain in operation by preventing sequential repetitive impact engagement of the link elements with a cone disk or cone pulley of the transmission.
