    摘要： A range-change transmission device, which is a splitter transmission, includes an input shaft, an output shaft, a countershaft, at least one planetary gear set, and a torque adjustment device. A first transmission element of the planetary gear set is arranged coaxially to the output shaft. A second transmission element of the planetary gear set is or can be directly coupled to the countershaft. A third transmission element of the planetary gear set is permanently coupled to the input shaft in a rotationally fixed manner. The countershaft is or can be coupled to the torque adjustment device. The range-change transmission device has a first switching unit, which is provided to couple the countershaft to the output shaft.

    摘要： A brake arrangement for a gearbox is provided, where the gearbox comprises an input shaft, a counter shaft, a main shaft and a plurality of gear wheels pairs which each comprises a primary gear wheel arranged on the counter shaft and a secondary gear wheel arranged on the main shaft. The brake arrangement further comprises at least two brake units each configured to act with a braking torque on the counter shaft or a component connected to the counter shaft, and a control unit configured to control the activation of the brake units. The control unit is configured to activate the at least two brake units one at a time or both simultaneously during an upshift process in the gear box when a secondary gear wheel of a gear wheel pair to be engaged in the gear box is retarded to a synchronous speed with the main shaft.

    摘要： A hydraulic synchronizer selectively couples one or more gears to a drive shaft. The synchronizer has a shaft hub with a splined annulus and a fluid passage. A ring is disposed about the shaft hub and movable along a rotation axis of the shaft hub. A shift collar is fixedly coupled to the ring and has a splined annulus engaged with the splined annulus of the shaft hub. The shift collar is configured to engage splines of a gear when the ring is in an engaged axial position and to disengage the splines of the gear when the ring is in a neutral position. The shift collar transmits rotational input from the shaft hub to the gear when the ring is in the engaged axial position. Hydraulic chambers receive hydraulic fluid from the fluid passage and move the ring to the engaged and neutral positions.

    摘要： The invention relates to a hybrid drive having an automated conventional gearbox, for example for a motor vehicle, having an internal combustion engine (VM) which has a drive connection to at least a first transmission input shaft (W1), having an electric drive which has at least one electric machine (EM1) which has a drive connection to a second transmission input shaft (W3; W3′), having at least one layshaft (W4), having freely moving wheels and fixed wheels (z11-z17, z21-z29, zR3) which are arranged in a plurality of wheel set planes (Z1-Z7), having a plurality of gear shift devices (S1-S4), and having a transmission output shaft (W2). In order to permit a high degree of variability in terms of a wheel set concept as well as the distribution and the number of electrical and internal-combustion-engine gearspeeds, to keep the expenditure on design and the costs low and to ensure efficient and comfortable operation, there is provision that the two transmission input shafts (W1, W3; W1, W3′) are arranged coaxially with respect to one another, and in that in one of its shifted positions a gear shift device (S1) connects the two transmission input shafts (W1, W3; W1, W3′) to one another effectively in terms of drive, and in another shifted position shifts a gearspeed.

    摘要： Provided with a hollow piping member attached in a casing and a guide member integrally installed on an outer peripheral surface of the piping member. The guide member is structured by a plurality of surfaces including a first surface on which at least part of hydraulic fluid pumped up by a final gear is received and a second surface connected to one end of the first surface extending along a side of the final gear, and fastened to the casing by a fastener. The guide member receives hydraulic fluid pumped up by the final gear, restraining the fluid from reaching a breather mechanism and neighborhoods thereof.
