A shift mechanism for a gearbox has a shift actuation unit designed to produce an axial shifting motion, at least two selector forks for shifting gear components to shift gears, and at least one shift rod designed to transmit the axial shifting motion from the shift actuation unit to at least one of the at least two selector forks. The coupling mechanisms and the shift rods are positioned to be axially aligned with one another.

Systems are provided for a gear set housing. In one example, a system comprises a gear box housing configured to house a four stage gear set in combination with a shift actuator and a differential lock, wherein the four stage gear set comprises an input shaft, a first layshaft, a second layshaft, and an output shaft.

The present application relates to a divided gear wheel 100, 200, for a power transmission system 1 of an automotive vehicle, to a power transmission system and a method to operate said power transmission system. The power transmission system comprises at least one divided gear wheel that comprises an inner part 130, 230, being engageable with a shaft and an outer part 110, 210, comprising teeth, adapted for torque transmission to another gear wheel. The inner part and the outer part have a common rotational axis, and the inner part is at least partially arranged within the outer part. Further, the inner part is coupled to the outer part by means of at least a set of two elastic elements, so that the inner part is arranged angularly deflectable with respect to the outer part around the common rotational axis. The inner part and the outer part are adapted to rotate with the same angular speed if the elastic elements are fully loaded.

The disclosure relates to an actuator arrangement for operating a clutch and a parking lock in a driveline of a motor vehicle, comprising: a clutch having a clutch actuating member configured to drivingly connect or disconnect a clutch input part and a clutch output part; a parking lock having a locking element movable to a locking position to lock a ratchet wheel, and to a release position to release the ratchet wheel; and a parking lock actuating member for actuating the locking element; a controllable actuator with a movable actuator setting member which is movable into at least three setting positions and is operatively connected to the clutch actuating member and to the parking lock actuating member such that in a first setting position the parking lock is closed, in a second setting position the clutch is closed, and in a third setting position the clutch and the parking lock are opened.

A power split transmission structure has at least three interfaces to direct driving power from a drive to at least one output in order to supply the driving power to connected consumers. It comprises at least two variator paths which each comprise a summation gearbox communicating with an electric or hydraulic machine via a mechanical and a non-mechanical path in order to modify torque, speed or both of the driving power. A control device regulates the summation gearbox of each of the variator paths. A power electronics system or hydraulic control device is connected to the electric or hydraulic machine of each of the variator paths. The transmission structure directs the driving power via the variator paths such that the electric or hydraulic machine of each variator path is operable in a generator or motor mode in order to compensate for a power shortfall or a power oversupply at at least one outlet of the transmission structure.
