    摘要： An automated multi-speed transmission includes an engine clutch operable to establish a releasable drive connection between the engine and an input shaft, an output shaft adapted to transfer power to the driveline, and a synchromesh geartrain having a plurality of constant-mesh gearsets that can be selectively engaged to establish a plurality of forward and reverse speed ratios. The transmission also includes power-operated dog clutches for selectively engaging the constant-mesh gearsets, and a controller for controlling coordinated actuation of the engine clutch and the power-operated dog clutches. The power-operated dog clutch associated with the low and the top gear are used during downshifts and upshifts, respectively, to actuate a clutch assembly for synchronizing the speed of the input shaft and the selected gear prior to engagement of its corresponding dog clutch.

    摘要： A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.

    摘要： A shaft clutch which may be designed as a dog clutch. In order to save axial construction space, the two end regions of the dog clutch are utilized for the transmission of torque from the shaft to the motor vehicle transmission member to be coupled. The middle region between the two end regions has solely the function of axial fixing during torque transmission and can be made correspondingly short axially.

    摘要： A method of returning an electro-mechanical axial setting device, wherein the axial setting device includes two setting rings centered on a common axis, one of which is axially held, and one of which is rotationally fixedly held in a housing. The two setting rings each include circumferentially extending grooves. Each of the grooves define a depth which rises in the circumferential direction. Pairs of grooves in the setting rings each accommodate a ball. The rotatingly drivable setting ring is connected to an electric drive motor. The axially displaceable setting ring is loaded by pressure springs towards the axially held setting ring. When applying a positive voltage to the electric motor, the axial setting device moves into an advanced position and when the voltage is disconnected from the electric motor, the axial setting device is returned into a starting position.

    摘要： A constant-mesh transmission having a synchronizing mechanism, the synchronizing mechanism including a fifth gear which acts as a shifter so as to rotate integrally with a counter shift and movably in the axial direction, a recess formed in a first gear, and a synchronizer ring. A first connection spline formed in the outer circumferential wall face of the recess and a first synchronization spline formed in the outer circumferential face of the synchronizer ring have a predetermined overlap portion, whereby they overlap partly in the axial direction. In the fifth gear, a second connection spline meshes with the first connection spline and a second synchronization spline presses the first synchronization spline in the axial direction to make the synchronizer ring and the first gear come into frictional engagement with each other.

    摘要： A method for control of a gear step change in a vehicle having a dual clutch transmission (2) actuatable by a prime mover (4), several gear steps in which a first dividing gear (6) and a second dividing gear (10) can be operatively coupled with the prime mover (4), respectively, by a first clutch (8) and a second clutch (12) and both dividing gears (6, 10) have a common output (14) wherein each dividing gear (6, 10) preferably has several ratio steps and at least two consecutive gear steps of the dual clutch transmission (2) are not associated with the same dividing gear (6, 10). It is proposed that upon a demand for a double downshift, a gear step change occurs within the same dividing gear (6) without the other dividing gear (10) transmitting during the gear step change a torque from the prime mover (4) to the output, and that the torque delivered by the prime mover (4) during the gear step change is essentially used for the acceleration of rotary masses on the side of the prime mover.
