A portable power tool has a drive unit for rotationally driving a tool receptacle about an axis of rotation, the drive unit having at least one drive motor and a shiftable transmission, which is arranged in a transmission housing with an at least partially sleeve-like clutch housing and a transmission cover fastened thereto. The tool includes a shifting element for shifting the shiftable transmission between at least two different gears, and a locking sleeve for locking the shifting element in at least a first and a second shifting position is arranged in the clutch housing. The shiftable transmission forms, at least in the first shifting position, a cross-sectional plane perpendicular to the axis of rotation in which the locking sleeve is arranged at least regionally between the transmission cover and the shifting element and the shifting element is arranged at least regionally between the locking sleeve and the clutch housing.

A commercial automotive vehicle, such as trucks and buses, having an auxiliary shaft associated with an auxiliary engine, a coupling and/or uncoupling device and a method for controlling the coupling and/or uncoupling between a shaft of commercial automotive vehicles and an auxiliary engine associated with the shaft. Specifically, the vehicle has a device that couples and/or decouples the effects of at least one auxiliary engine to a shaft, allowing that, in a coupled state, the shaft receives auxiliary traction from the auxiliary engine or the auxiliary engine acts as a generator of braking energy in a regenerative way and, in a decoupled state, it allows the shaft to rotate freely so that no energy losses occur due to friction of the device components.

A connecting arrangement includes first and second idler gears (6, 7) arranged coaxially and connectable via an engagement unit. The engagement unit includes a coupling element coupled to the first idler gear (7) in a direction of rotation and axially movable between a home position and a coupling position. In the coupling position, the coupling element is coupled to the second idler gear (6) in addition to being coupled to the first idler gear (7) in the direction of rotation. In the home position, the coupling element and the second idler gear (6) are freely turnable with respect to each other. The first and second idler gears (6, 7) are helical-cut spur gears. The coupling element is guided in a helically extending guide (18) on the first idler gear (7) and, in the coupling position, engages into a helically extending engagement geometry (21) on the second idler gear (6).

A clutch coupler assembly for a hybrid transmission having a first torque input, a second torque input, and a torque output comprises a sleeve fixed to the first torque input and an output hub connected to an output shaft of the torque output. A first ring is disposed on an outer diameter of the output hub and fixed to the sleeve such that the first torque input is always coupled to the torque output. An input hub is connected to an input shaft of the second torque input and a second ring is disposed on an outer diameter of the input hub. A sliding collar is mounted on the first ring and is configured to engage with the second ring to selectively connect the second torque input to the torque output.

A commercial vehicle with at least one driven axle, at least one service brake, at least one propulsion engine, and wheels characterized in that the parking brake function of the vehicle is solved by a bistable locking means acting on both wheels. At least one multi-speed gearbox is provided to concurrently activate a first gear stage and a second gear stage having different ratios.

A dog clutch of a vehicle power transmission device includes a sleeve, the dog clutch connecting/disconnecting a first rotating shaft to/from a first gear by moving the sleeve between a neutral position at which inner circumferential teeth formed on an inner circumferential side of the sleeve are not meshed with outer circumferential teeth on a side surface side of the first gear and an engagement position at which the inner circumferential teeth are meshed with the outer circumferential teeth, the inner circumferential teeth and the outer circumferential teeth having inclined surfaces tooth thicknesses of which become larger as the inner circumferential teeth and the outer circumferential teeth approach each other, and when the sleeve is moved to an engagement position by a shift fork, the sleeve being held in contact with a side surface of the first gear.
