Abstract
The invention relates to a continuously variable transmission. The continuously variable transmission comprises an outer rotary part, an inner rotary part which is arranged in the outer rotary part such that the inner and/or the outer rotary part are rotatable relative to one another, several coupling mechanisms for coupling the inner and outer rotary part with one another, an adjustment device for eccentric adjustment of the inner and outer rotary part relative to one another, a pump for delivering a lubricant into the transmission along a shell surface of the inner rotary part, and sealing elements which are arranged on the inner rotary part in the coupling mechanisms, or nozzles for delivering a predetermined amount of lubricant to the particular coupling mechanism.

A continuously variable transmission comprising:
- an outer rotary part,
- an inner rotary part which is arranged in the outer rotary part such that the inner and/or the outer rotary part, are rotatable relative to one another,
- a plurality of coupling mechanisms for coupling the inner and outer rotary part with one another,
- an adjustment device for eccentric adjustment of the inner and outer rotary part relative to one another,
- a pump for delivering a lubricant into the transmission in an axial direction along a shell surface of the inner rotary part,
- and sealing elements which are arranged on the inner rotary part in the coupling mechanisms, or nozzles for delivering a predetermined amount of lubricant to the particular coupling mechanism,
- wherein the outer rotary part has discs which are spaced apart by bearing bolts for the coupling mechanisms.
