摘要： A method and system are provided for controlling the operating temperature of a torque converter during torque converter stall conditions. The torque converter has a pump rotatably driven by an internal combustion engine and a rotatable turbine fluidly coupled to the pump. The system first determines whether the torque converter is currently in a torque converter stall condition, and, if so, determines a slip speed as a difference in rotational speeds between the pump and the turbine, determines an engine output torque limit as a function of the slip speed and a desired slip speed, and controls the operating temperature of the torque converter by limiting output torque produced by the engine based on the engine output torque limit.

摘要： A speed changing mechanism includes a pump (1) including a liquid suction channel (6), a liquid drainage channel (8) and working components (3, 4) moving relatively to each other forming working volumes. A relative movement of the working component leads to a periodic increase and decrease of the working volume, so that the fluid is sucked through the liquid suction channel and discharged through the liquid drainage channel, and the pressure energy discharging the fluid is increased by the excursion of the working components. A part of working components is connected to an input component, another part of working components are connected to an output component. The movement of the part of working components relative to another part of working components is changed by changing the flow rate of the pump. Therefore, the speed changing mechanism can realize the switch-on/off of power transmission and change the transmitted power.

Said clutch comprises at least one first and a second clutch part (2, 55; 1, 53). The aim of the invention is to create a clutch which can be switched during operation, operates essentially without dissipating power, and is wear-free and thus maintenance-free. Said aim is achieved by at least one hollow chamber in the first clutch part (2, 55), said hollow chamber being open on at least one side, forming at least one fluid chamber (12, 63), and being closed by a wall on the second clutch part (1, 53), the hollow chamber and the wall being movable relative to each other, as well as at least one slide (17) which is mounted on the second clutch part (1, 53) in the area of the wall and by means of which the fluid chamber (12, 63) can be subdivided at least in part perpendicular to the direction of the relative movement.

摘要： A hydrostatic transmission comprising a housing formed with a fluid sump, a center section, a hydraulic pump, and a hydraulic motor. A fluid passage is formed in the center section. A bore is open at an outer surface of the center section in communication with the fluid passage. An output operation device is provided for controlling discharged fluid of the hydraulic pump. A piston having an outer surface is reciprocally inserted into the bore so as to be allowed to project outward from the center section. A valve is disposed within the bore. The valve is biased to be closed by a spring disposed between the valve and the piston. A member interlocks with the output operation device so as to contact with the outer surface of the piston.

摘要： A gear pump mechanism shown in a variety of applications to control rotational output. Control of the output from the gear pump and feed to the gear pump of hydraulic fluid or oil can be controlled to establish conditions from free wheeling to fully locked. The gear pump includes a sun gear and planetary gears. The sun gear is attached to an output shaft while the planetary gears are rotatably mounted to the pump housing. Through rotation of the housing and control of the flow through the gear pump, relative rotation of the output shaft can be determined. Applications of rotational output control systems using the gear pump mechanism provide adjustable torque limiters, variable rate clutches, differentials, brakes, CVT transmissions, four wheel drive systems and forward and reverse variable rate clutches with no gear backlash.

摘要： A temperature-controlled fluid coupling for intermittently driving a cooling fan of an internal combustion engine. The coupling comprises a drive input shaft having a rotor thereon, a housing for supporting a cooling fan, a plurality of radial vanes accommodated within the rotor, and a valve member within the housing. The vanes are movable in radial directions within an elliptic chamber in the housing. The rotor and the vanes provide a kind of vane pump system. A temperature sensitive element is disposed outside of the housing and connected to the valve member. The element operates to open and close the valve in response to a change of ambient temperature. The fan rotates to cool the engine only when the temperature goes up to a predetermined level.

摘要： A controlled type rotation speed difference sensitive coupling is disclosed, which is for use between first and second rotatable members. The coupling comprises a drive housing connected to the first rotatable member, a rotor connected to the second rotatable member and rotatably received in the housing, and driving pistons operatively carried by the rotor having head portions thereof slidably engaged with a cam surface wall formed on an inner surface of the drive housing. The rotor has at its center portion a spool chamber in which a spool is disposed. Balance passages and relief passages extend respectively between working chambers defined by the driving pistons and the spool chamber. Each balance passage has an orifice which is exposed to the spool chamber and closable by the spool. The orifice is non-circular in shape.

摘要： Utilizing the characteristic that a hydraulic pump, such as a gear pump, having the fluid flow from its outlet restricted will tend from the increasing internal pressure to rotate with the input shaft, a variable speed transmission is designed which includes such a hydraulic pump having a rotating input shaft coincident with the input shaft of the transmission, a fluid flow regulating unit between the fluid outlet and fluid inlet of the pump, and an output shaft connected to the external housing of the pump. The fluid flow regulation unit, which includes a first fluid containing chamber connected to the pump outlet and a second fluid containing chamber connected to the pump inlet, adjustably varies fluid flow between the two chambers. A cylindrical sleeve member, having a plurality of perforations interconnecting the two fluid containing chamber, and a blocking piston slidably installed within the cylindrical sleeve permit variation between no and full fluid flow. The blocking piston, extending concentrically within an output stem of the enclosing transmission housing, is tranversely penetrated by a pin so that the pin ends extend through a pair of opposing longitudinal slots formed in the output stem. A collar fits about the output stem to engage the pin ends so that longitudinal movement of the collar adjusts the location of the blocking piston within the perforated sleeve, permitting control of pump flow and thus rotation of the output shaft.
