摘要： A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

摘要： A method and a device for controlling an automatic or automated clutch (4) of a vehicle, by a pressure fluid drive actuator (6) whereby the waypoint of a part (piston rod 12), connected with the drive actuator (6), is captured via a displacement sensor (28) and entered, as a control parameter, into a clutch control interacting with the vehicle control system (26). Provision is made for a diversified redundancy by use of a pressure sensor (30) measuring the fluid pressure in the drive actuator (6). The pressure sensor (30) monitors and stores the pressure in the drive actuator (6) and pressure changes, when engaging or disengaging the clutch, as a curve in the vehicle control system (26). Hereby, the level of engagement of the clutch is represented by the waypoint of drive actuator (6) by the pressure in the drive actuator (6) so that, if there is a malfunction in the displacement sensor (28), an emergency drive function is maintained.

摘要： A torsional spring system is provided and is made from a single wire having a first end and a second end, and being wound to define a plurality of coil sections each separated from one another by a plurality of torsion arms. The first and second ends of the wire are joined to one another such that the plurality of coil sections and the plurality of torsion arms combine to form a loop. The torsion spring of the present invention can be utilized as a return spring in a clutch system for reducing the cost of the overall assembly. In addition, the torsion spring of the present invention also provides added functionality by being capable of simultaneously counteracting any combination of axial, radial, and rotational forces.
