  • CONTINUOUSLY VARIABLE TRANSMISSION
    Publication number: 20230313872
    Abstract: Aspects of the present disclosure relate to a powertrain assembly including a continuously variable transmission and, in some examples, a clutch. The clutch may be operably coupled between a prime mover and the continuously variable transmission. Additionally, or alternatively, a clutch may be operable coupled after or downstream of the continuously variable transmission. Aspects of the powertrain assembly may be controlled to provide starting-clutch functionality, to provide torque-limiting functionality, and/or to adapt operation of the powertrain for any of a variety of conditions.

  • Electronic CVT with friction clutch
    Patent number: 11543005
    Abstract: A continuously variable transmission (“CVT”) is provided for use on a recreational or utility vehicle. The CVT is electronically controlled by a control unit of the vehicle. The CVT includes a primary clutch having a first sheave, a second sheave movable relative to the first sheave, and a friction clutch. An actuator assembly is configured to actuate the primary clutch and cause movement of the second sheave.
