Vehicular front axle powertrain, which uses an electric motor with an external rotor is for driving and braking of the front axles of vehicles with wheels which also or only use electrical power. It consists of an electric engine (1) with an external rotor or rotor extension (1.2), which is also a generator working as a brake. The rotor or rotor extension (1.2) connects to a clutch (3), which guards against overload and may have a disc brake (3.I) mounted, which carries excess braking force. The clutch (3) connects to an internal joint (4), which connects to a shaft (5), which has an external homokinetic joint (6) with a hub shaft (6.2) for the vehicle's wheel. Rotational energy goes from the electric motor (I) without mechanical losses to the hub shaft (6.2) and back, while the hub shaft (6.2) can move relative to the stator in the (SA) and (SB) directions.

The invention relates to a device (1) for the horizontal re-centering of a coupling shaft, particularly a central buffer coupling of a track-guided vehicle, wherein the device (1) comprises a first rotating body (3) and a second rotating body (4) which is rotatable relative to the first rotating body (3), wherein the device (1) is designed to produce the force necessary to generate a restoring torque acting on the coupling shaft by the rotating of the two rotating bodies (3, 4) relative to each other.

A dynamic vibration absorber is configured to be attached to a rotary member. The dynamic vibration absorber includes a base member, a mass body, and a torque limiting part. The base member is rotatably disposed. The mass body is attached to the base member so as to be rotatable relatively thereto. The torque limiting part limits transmission of a torque to be inputted into the base member from the rotary member.

A planetary gear system with a sun gear, a ring gear co-axial with the sun gear, at least one planetary gear meshing with both the sun gear and the ring gear, and a planetary gear carrier which rotationally supports the at least one planetary gear. A torque clutch is supported by and connected directly between two of the sun gear, the ring gear, the at least one planetary gear and the planetary gear carrier. The torque clutch prevents relative rotation when an acting torque is below a predetermined torque value and allows relative rotation when the acting torque is above the predetermined torque value. A torque threshold adjustment mechanism is provided for adjusting the predetermined value of the torque at which the torque clutch slips.
