ELECTRIC VEHICLE WITH POWERTRAIN HAVING REVERSE-ACTING CENTRIFUGAL CLUTCH

DRIVE October 9, 2025
Source
An electric vehicle includes an electric drive motor, transmission, and centrifugal clutch. The centrifugal clutch is drivingly coupled in a torque transmission path between the electric drive motor and the transmission. The centrifugal clutch includes a first friction plate, second friction plate, biasing member, and counterweight. The first friction plate is rotatable about an axis. The second friction plate is rotatable about the axis and axially movable relative to the first friction plate. The second friction plate is configured to frictionally engage the first friction plate to transmit torque therebetween. The biasing member biases the second friction plate toward the first friction plate. The counterweight assembly is coupled to the second friction plate and configured to apply a counterweight force on the second friction plate away from the first friction plate in response to a rotational speed of the second friction plate exceeding a predetermined rotational speed.
