Abstract

A continuously variable transmission for a motor vehicle. The transmission includes an adjustable width drive pulley and an adjustable width output pulley that are drivingly connected by an endless torque-transmitting member. The drive pulley includes a spring to bias the movable element of the pulley toward a position at which the spacing between the conical disks that define the pulley are at a minimum, to avoid damage to the transmission when the vehicle is being towed.
