    Abstract: A combination starter-generator device for a work vehicle includes an electric machine and a bi-directional gear set. The gear set is configured to receive rotational input from the electric machine and from the engine and to couple the electric machine and the engine in a first power flow direction and a second power flow direction. In the first power flow direction the gear set effects a first gear ratio, and in the second power flow direction the gear set effects a second gear ratio. In the first power flow direction, the gear set receives input power from the electric machine in a first clock direction and outputs power to the engine in a second clock direction opposite the first clock direction. In the second power flow direction, input power from the engine is in the second clock direction and output power to the electric machine is in the second clock direction.

    Abstract: In an actuator having a reversible motor before a step-down gear, this can be optimized kinetically, geometrically and in terms of material engineering when different step-down ratios become active according to the different torque requirement for application and for release, in a manner dependent on direction of rotation, for example of a parking brake operated by an electric motor. For this purpose, two differently dimensioned idler wheels of the step-down gears that mesh, for example, with a stepped motor pinion, act via freewheels acting in opposite directions on a common gear shaft. Depending on direction of rotation of the motor, the gear shaft thereby rotates at different rpms, delivering correspondingly different torques.

    Abstract: A dual clutch transmission including two sub-transmissions, each having an input shaft arranged on an input axis, an intermediate shaft and an output shaft which is the drive output of both sub-transmissions. The intermediate shaft can be connected to the input and output shafts. The transmission also has wheel planes, shifting elements, two clutches and countershafts. A first countershaft can be connected to transmission elements of all the wheel planes on the countershaft axis and a second countershaft is connected to transmission elements of at least two wheel planes. The shifting elements include at least one single shifting element, but most of the shifting elements are double shifting elements. Two shifting elements are arranged on the input axis between two wheel planes, whose transmission elements are connected to the second countershaft. Opposite sides of the intermediate shaft are respectively connected to a range group and the output shaft.

    Abstract: A transmission includes a main shaft having two or more main shaft clutches that couple gears to at least one countershaft, and an automated manual transmission coupled to the main shaft via the at least one countershaft. The automated manual transmission includes a front input shaft coupled directly to a main clutch and having a first clutch coupleable to the at least one countershaft, and a rear input shaft coupled to the front input shaft and having a second clutch coupleable to the at least one countershaft. The automated manual transmission is operable to selectively engage the first clutch and the second clutch.

    Abstract: A dual clutch transmission for motor vehicles has first and second input shafts, two clutches selectively coupling the input shafts the engine, two intermediate shafts arranged parallel to the transmission input shafts, gearwheel pairs configured to transmit power between the input shafts and the intermediate shafts, and output gearwheels arranged on each of the two intermediate shafts. The output gearwheels mesh with the differential wheel and are selectively coupled to the respective intermediate shaft by one of the coupling devices. An additional intermediate gearwheel set is provided, that one gearwheel of the intermediate gearwheel set is seated on the first or second intermediate shaft, that the other gearwheel of the inter-mediate wheel set is arranged on a third intermediate shaft, and that a third output gearwheel, which meshes with one of the output gearwheels of the first or second intermediate shaft, is seated on the third intermediate shaft.
