ABSTRACT:
A cone ring transmission, especially for motor vehicles with a front, transverse drive is proposed, having two cones in opposed alignment to one another, rotating on two shafts, the cones being, namely a primary cone and a secondary cone, with an adjustment ring engaging both cones therebetween, the ring contacting one cone and circumferentially encompassing the other cone, with a mechanism to provide ratio adjustment for the adjustment ring, having an arrangement which binds the output drive shaft, i.e. the shaft of the secondary cone with a differential of the motor vehicle and with a start-up element, which binds one of the cones with the motor of the motor vehicle, whereby the torque from the output drive shaft is transmitted to a differential by way of a gear train.
