摘要： 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.

摘要： An operation control system for a hydraulically operated clutch of a fluid torque converter wherein the clutch mechanically couples the input and output of the torque converter under certain conditions. Pressure chambers on either side of the clutch plate are pressurized to operate the clutch. An orifice through the clutch plate allows flow from one chamber to the other. A regulator valve is connected to both pressure chambers and is responsive thereto. The regulator valve is also responsive to external signals such as vehicle speed and throttle opening to regulate the pressure difference in the two chambers for operation of the clutch.

摘要： A continuously variable hydraulic transmission operatively interconnects a transmission mechanism and a clutch mechanism. The hydraulic transmission includes an oil pump having an inlet port and an outlet port and a transmission ratio control member such as a swash plate which is displaceable for varying the transmission ratio between a higher-speed position, a lower-speed position, and a neutral position, an oil motor having an inlet port and an outlet port and drivable by the oil pump, a first oil passage hydraulically interconnecting the outlet port of the oil pump and the inlet port of the oil motor, a second oil passage hydraulically interconnecting the inlet port of the oil pump and the outlet port of the oil motor, a housing accommodating the oil pump, the oil motor, the first oil passage, and the second oil passage, and an oil passage control unit for selectively bringing the first oil passage into and out of hydraulic communication with the second oil passage. The oil passage control unit is fully accommodated in the housing and actuatable by the transmission ratio control member to bring the first and second oil passages into hydraulic communication with each other only when the transmission ratio control member is near the neutral position.
