摘要： A transmission mechanism in particular for automobiles with a front wheel drive comprises a planetary forward-reverse gear set and a continuously variable pulley drive that is drivingly connected to a differential gearing. A forward friction disk clutch provided for obtaining a forward driving direction of the transmission mechanism may be selectively operated by a servo piston that is fixedly connected in an axially stationary manner to the adjusting piston of a hydraulic adjusting means provided for the selective adjustment of the movable sheave of a primary pulley of said pulley drive whereby the mutual arrangement is chosen in such a manner that the adjusting cylinder being fixedly connected to this movable sheave at least partly surrounds the servo piston. By this particular arrangement the axial dimension of the entire transmission mechanism may be reduced without the requirement of a separate starting clutch for the entire clutch assembly.

摘要： The invention relates to a transmission for vehicles, in particular for automobiles with front wheel drive, which have a driving motor mounted transverse to the longitudinal direction of the vehicle, whose drive shaft drives the primary shaft of an infinitely variable belt drive having a secondary shaft driven in the same direction of rotation by means of a drive belt and mounted coaxially with the drive pinion of a differential gear provided with output shafts. A reversing and reduction gearing, designed as a planetary gearset, is mounted coaxially with the secondary shaft of the belt drive and connected through its input member to the secondary shaft and through its output member to the drive pinion of the differential gearing, while its reactive section is fixed to the casing. As a result, a very compact transmission unit is achieved, having in forward drive position an output rotation in the same direction as the input rotation.

摘要： The invention concerns a stepless variable belt transmission with pulleys which comprise two axially movable conical halves. The displacement of the pulley halves is effected by hydraulic piston-cylinder units rotating along with the pulleys. At least one hydraulic piston-cylinder unit is provided with a compensation chamber wherein a pressure is built up as a function of the speed. According to the invention the compensation chamber communicates with a closable opening with the cylinder chamber by means of which the pulley halves are relatively moved.
