Abstract
A wheeled vehicle has an internal combustion engine provided with an air intake having a throttle valve. A change speed transmission drives certain of the wheels and receives power from a fluid torque converter having an impeller driven by the engine and a turbine connected to drive the change speed transmission. A clutch establishes a direct drive between the impeller and the turbine under certain operating conditions of the vehicle and the clutch operation is controlled by an hydraulic circuit. Valves and controls are provided in the hydraulic circuit and responsive to the vehicle speed to allow slipping of the clutch at low speeds and direct drive coupling of the clutch at high vehicle speeds. The clutch is further controlled by the throttle opening to limit the direct drive coupling under high vehicle speeds and large throttle openings. In one form the clutch is also controlled by a fluid by-pass mechanism to allow slipping of the clutch during low torque transmitting conditions.
