Gear arrangement for the controllable distribution of a drive torque from an input element to at least one output element in an all-wheel drive train of an all-wheel drive motor vehicle

摘要

Gear arrangement (1) for the controllable distribution of a drive torque from an input element (2, 2 ') to at least one output element (3, 3', 3 ") in an all-wheel drive train of a four-wheel drive motor vehicle, comprising - an additional drive unit (4, 4 '), - one first transmission section (5, 5 '), the first transmission section (5, 5') being directly or indirectly connected to the auxiliary drive unit (4, 4 ') in a drive-effective manner, - a second transmission section (6, 6'), the first transmission section (5, 5 ') is indirectly connected to the output element (3, 3', 3 ") via the second gear section (6, 6 '), and - a switching element (7, 7'), the switching element (7, 7 ') is movable in three switching positions, namely a first switching position, the all-wheel-drive mode, in which the first gear section (5, 5') is functionally connected to the input element (2, 2 ') in the function of a power summing gear, a second switching position , the recuperation position, in the the first transmission section (5, 5 ') is connected to the second transmission section (6, 6') in a drive-effective manner, and a third switching position, the disconnect mode, in which the first transmission section (5, 5 ') neither with the input element (2 , 2 ') is still connected to the second gear section (6, 6') in a drive-effective manner.
