ABSTRACT:
A continuously variable non-stage transmission for a vehicle includes a pair of pulleys with a belt wound around them, and an arrangement cooperable with the pulleys for varying the radius of gyration of the belt. A fluid coupling, a reverse drive brake, a neutral clutch, and one of the pulleys are positioned in a row beginning at the vehicle engine and extending along a rotatable shaft. The fluid coupling includes a pump impeller, a turbine runner, and a stator wheel which is lockable against rotation by the brake to provide reverse rotation of the turbine runner. A direct clutch is built into the fluid coupling and prevents cavitation in the fluid coupling. An operating mechanism of the brake is fitted in a hollow cavity in the case of the transmission. The cavity is formed by a retaining portion of the transmission case, which retaining portion supports a bearing of the rotatable shaft.
