摘要： A change-speed transmission in the power train of a motor vehicle has a planetary gearing and coaxial radially inner and outer disc clutches, namely a direct clutch and a reverse clutch. At least that clutch which is engaged (i.e., in use) is cooled by a lubricant for the planetary gearing, and the flow of coolant to the clutches is regulated by the axially movable pressure plate of one of the clutches. A jet pump conveys lubricant from the sump in the transmission case into an axially extending channel of the input shaft of the transmission, and such channel forms part of a system of passages which supply coolant at least to that clutch which is then in use to transmit torque from the input shaft to an output element of the transmission.

摘要： A decoupling device for the bearing arrangement of a shaft carried in a housing, in particular a shaft of a belt-driven conical-pulley transmission with a chain that functions as the belt. The decoupling device includes an outer bearing ring configured with a circularly cylindrical outer surface and within which the shaft is mounted, and an inner surface of a housing that encloses the bearing ring outer surface. At least one radial ondular washer is arranged between the bearing ring outer surface and the housing inner surface, which allows a limited relative radial movement between the housing inner surface and the bearing ring outer surface by elastic deformation of the washer.

摘要： A torsional vibration damper, particularly for use between the engine and the transmission of the power train in a motor vehicle, including two flywheels rotatable relative to each other against the opposition of a first energy storing device employing, for example, one or more coil springs and a second energy storing device, which is carried by one of the flywheels, which operates in parallel with the first energy storing device and which opposes rotation of the two flywheels relative to each other. In order to isolate the irregularities of movement of the first flywheel (such as vibrations which develop while the engine is in operation) from the second flywheel, the second energy storing device (such as a snap spring or a set of diaphragm springs) is coupled to the flywheels in such a way that the second flywheel develops a degressive action only when the first flywheel is caused to move through relatively small angles (especially between 1° and 10°) but not when the angles are larger (especially larger than 10°).

摘要： A continuously variable transmission including a drive element rotatable about a drive axis, an output element rotatable about an output axis parallel to the drive axis, and an adjusting mechanism with which the drive axis and the output axis can be laterally offset from each other. Coupling elements operate between the drive element and the output element and are spaced from each other in the peripheral direction of the drive element and output element for transmitting torque between the elements. The coupling elements change the movement of a peripheral region of the drive element faster than that of the output element so that forces acting on the coupling elements from the drive element and the output element lie substantially in a common plane that extends perpendicularly to the axes of rotation. The continuously variable transmission can be incorporated into a transfer case for an all-wheel drive system.

摘要： An adjustable pulley for use in a continuous variable transmission in the power train of a motor vehicle has an axially fixed first conical flange and an axially movable second conical flange. The hydraulic control system which moves the second flange relative to the first flange is provided with at least one first plenum chamber which receives pressurized fluid when the second flange is to move toward the first flange, and with an additional plenum chamber which receives pressurized fluid when the second flange is to move away from the first flange. The admission of pressurized fluid into the additional chamber is regulated in dependency upon the RPM of the flanges. Rapid evacuation of pressurized fluid from the additional chamber can take place by way of a relief valve which opens when the pressure of fluid in the additional chamber rises to a preselected value. This renders it possible to rapidly shift between overdrive and underdrive.
