Abstract

A drive arrangement for a drive train of a vehicle is disclosed. In one aspect, the drive arrangement includes at least one transmission element configured to transmit a force and/or a torque and at least one joint. The transmission element and the joint are configured to be connected reversibly in a force transmitting manner and/or in a torque-transmitting manner.

First claim

What is claimed is:

1. A drive arrangement for a drive train of a vehicle, the drive arrangement comprising:
at least one transmission element configured to transmit a force and/or a torque;
at least one joint; and
at least one actuating device configured to perform and/or cancel a force transmitting connection and/or a torque transmitting connection between the transmission element and the joint,
wherein the transmission element and the joint are configured to be connected reversibly in a force transmitting manner and/or in a torque-transmitting manner,
wherein the joint comprises at least one outer part with ball tracks, an inner part with ball tracks arranged at least partially in the outer part, a window containing cage being placed between the outer part and the inner part, and balls being arranged in the windows of the cage,
wherein the transmission element is rotatable along a rotational axis, wherein the joint is rotatable along a longitudinal axis, and wherein the outer part and the inner part are movable along the longitudinal axis relative to each other.

2. The drive arrangement according to claim 1 , wherein the actuating device is configured to move the outer part and the inner part in such a way relative to one another that the balls are arranged outside of the ball tracks of the outer part.

3. The drive arrangement according to claim 2 , wherein the actuating device has at least one sliding sleeve, over which the actuating device moves the outer part relative to the inner part.

4. The drive arrangement according to claim 2 , further comprising a loose ring arranged adjacent to the ball tracks of the outer part, wherein the actuating device is configured to move the outer part in such a way relative to the inner part, and wherein the balls are arranged inside the loose ring.

5. The drive arrangement according to claim 4 , wherein the loose ring is pivoted in at least one bearing element.

6. The drive arrangement according to claim 1 , wherein the actuating device is configured to move the outer part relative to the inner part, and wherein the balls are arranged within the ball tracks of the outer part and within the ball tracks of the inner part.
