Methods are provided for adapting clutches for use in unconventional drive trains, for example those used in hybrid vehicles having a electric motor/generator.
摘要:
A clutch-actuating device for a clutch in a motor vehicle power train has an actuator motor driving an actuating member and a transfer mechanism which transmits the movement of the actuating member to a clutch release element that is movable against an opposing force of a clutch spring to displace the clutch from a closed position to an open position. The transfer mechanism has a first movement range in which the movement of the actuating member in the opening direction of the clutch does not displace the clutch from its closed position, and a second movement range in which the movement of the actuating member causes a displacement of the clutch. The transfer mechanism has an interval of loose play, which is used up within the first range.
摘要:
A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a selector finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.

摘要:
A shiftable gear transmission has a plurality of gear pairs with free gears that can be engaged to one of the shafts by means of shift clutches and fixed gears that are permanently locked to one of the shafts. A start-up clutch arranged at the input side of the transmission couples and uncouples the torque flow. At least one of the shift clutches is a power-shift clutch with the ability to transmit a greater amount of torque than the other shift clutches. The start-up clutch and the power-shift clutch are controlled by at least one actuator unit.

In a power-shift transmission that is coupled to the engine of a vehicle and uses a frictional slip clutch as a power-shift clutch, the gear-shifting process is controlled under a method wherein the torque generated by the engine and the clutch torque transmitted through the frictional slip clutch are varied in such a manner that the temperature rise of the frictional slip clutch is lessened.
摘要:
A motor vehicle transmission, shiftable between different transmission ratios, with an input shaft, an output shaft, and in some cases a countershaft has a plurality of gears arranged to cooperate in gear pairs, a plurality of clutches, and an electro-mechanical energy converter. The electro-mechanical energy converter can be coupled to the transmission through at least one of the clutches in order to perform at least one of the functions of starting the combustion engine of the vehicle, temporarily replacing or assisting the combustion engine in propelling the vehicle, maintaining vehicle traction during gear shifts, generating electrical energy from kinetic energy, and storing said electrical energy in a storage device.
