There is a constant need for an increased life in the drive train of a motor vehicle to reduce power loss.

Subject of the invention

It is the object of the invention to show measures that allow for a drive train of a motor vehicle a long life and low power loss. In particular, it is the object of the invention to show measures that allow low power loss in hybrid vehicles, in which in particular via a provided in a wheel bearing module hub motor, a motor vehicle wheel can be driven purely electrically.

The object is achieved according to the invention by a wheel bearing module for driving and / or bearing a motor vehicle wheel with the features of claim 1, a use of a wheel bearing module with the features of claim 9 and a method for driving and / or storing a motor vehicle wheel of a motor vehicle with the features of claim 10. Preferred embodiments of the invention are specified in the subclaims.

According to the invention, a wheel bearing module for driving and / or supporting a motor vehicle wheel is provided with a hub for connection to a rim of the motor vehicle wheel and a rotatable relative to the hub rotatably mounted drive shaft of a joint bell for particular pivotal connection with a propeller shaft for initiating a provided by an internal combustion engine torque According to the invention in the radial direction between the hub and the drive shaft slidable in the axial direction sliding sleeve is provided, wherein the sliding sleeve is rotatably connected in an axial drive position with the hub and the drive shaft and in an axial freewheeling position relative to the hub and / or to the drive shaft is relatively rotatable , wherein a latching device is provided for the axial locking of the sliding sleeve in the drive position and / or in the freewheeling position.

By arranged in the radial direction between the drive shaft of the bell crank and the hub sliding sleeve, the sliding sleeve is positioned in an inner region of the wheel bearing module and better protected from contamination, whereby the wheel bearing module is made more robust and the life of a drive train can be increased with such a wheel bearing module. At the same time, it is possible in an idling mode and / or in an operating mode in which the motor vehicle wheel is driven purely electrically and not by an engine connected via the articulated bell, to throw over the drive shaft on the vehicle wheel attacking drag torques and thereby reduce power loss in the drive train. In particular, the wheel bearing module is used for all motor vehicle wheels of the motor vehicle.

By the latching device, a defined axial position for the sliding sleeve in the drive position and / or the freewheeling position can be ensured, wherein the sliding sleeve can be held in the desired position even with attacking forces or vibrations.

Since the sliding sleeve is not provided radially outward to the hub, but in particular is arranged completely radially within the hub, it is not necessary that the hub has a radially outwardly projecting flange for forming an external toothing for the sliding sleeve. Instead, the hub may be configured as a hollow shaft with an internal toothing. This makes it possible to attach components positioned radially outside the hub during assembly of the wheel bearing module at the end of the hub pointing to the joint bell. Particularly preferably, a mounting flange, via which a rim of the motor vehicle wheel can be connected to the hub, are integrally formed with the hub at the end of the hub pointing away from the joint bell. As a result, it is not necessary to fix the mounting flange relative to the hub in the axial direction by means of additional components. Instead, the integrally formed with the hub mounting flange can serve as a stop for at least one plugged onto the hub component. The number of components, in particular required for the connection of the motor vehicle hub hub number of components can be reduced, whereby the assembly of the wheel bearing module can be accelerated and simplified. Further, it is not necessary to rotatably connect the mounting flange via a spline with the hub, so that a relative displacement of the mounting flange is avoided to the hub in the circumferential direction during operation of the motor vehicle, which among other wear effects and reaching into the interior of the wheel bearing wear is avoided.

About the joint bell, the propeller shaft can be coupled for the transmission of torque. In this case, the propeller shaft is in particular substantially fixed in position to the underbody of the motor vehicle, while the motor vehicle wheel is connected in particular via shock absorbers relatively movable to the underbody of the motor vehicle. The wheel bearing module can join together with the motor vehicle wheel, the relative movement to the underbody of the motor vehicle, the joint bell can compensate for the changing orientation of the wheel bearing module to the propeller shaft. For this purpose, the joint bell is designed in particular substantially hollow-sphere-like, wherein the propeller shaft can be rotatably coupled in the hollow sphere-like region via a corresponding spline. Depending on the relative position of the wheel bearing module to the propeller shaft, the torque transmission of the propeller shaft with the joint bell via another portion of the hollow sphere-like region of the spline of the joint bell takes place.

In particular, the drive shaft is formed integrally with the joint bell to form a common structural unit. Under the drive shaft that part of this assembly is understood, which is arranged radially in the assembled state of the wheel bearing module inside the hub and is hidden in a view from radially outside of the hub. The projecting in the axial direction of the hub part of the assembly is understood as part of the joint bell.

In particular, the motor vehicle wheel has a tire, via which the drive torque transmitted to the motor vehicle wheel can be transmitted to a substrate in order to move the motor vehicle. The tire can be held by a rim that can be directly or indirectly connected to the hub.

The sliding sleeve can be frictionally connected in the drive position, for example via wedging wedges, and / or positively, for example via a spline, with the hub and the drive shaft. The non-rotatable connection of the sliding sleeve with the hub and the drive shaft is in particular so strong that a provided maximum of the joint bell coming to be transmitted torque can be completely transferred via the sliding sleeve to the hub. In the freewheeling position, a frictional engagement and / or a positive locking is canceled at least with the hub or the drive shaft, so that a torque flow between the drive shaft and the hub is interrupted via the sliding sleeve. Preferably, the sliding sleeve in the freewheeling position is non-rotatably connected to the drive shaft, so that even a due to the inertial mass of the sliding sleeve drag torque can not affect acceleration and / or deceleration of the vehicle wheel in the freewheeling position.

In particular, it is provided that the sliding sleeve at least two over an axial distance d _S having spaced apart external teeth for rotationally fixed meshing with an internal toothing of the hub, wherein the internal toothing has an axial width b _N wherein 1.00 ≦ d _S / b _N ≦ 1.50, in particular 1.01 ≦ d _S / b _N ≦ 1.25, preferably 1.02 ≦ d _S / b _N ≦ 1.10 and particularly preferably 1.03 ≦ d _S / b _N ≦ 1.05 applies, and / or the hub at least two over an axial distance d _N having spaced apart internal teeth for rotationally fixed meshing with an external toothing of the sliding sleeve, wherein the external toothing has an axial width b _s wherein 1.00 ≦ d _N / b _S ≦ 1.50, in particular 1.01 ≦ d _N / b _S ≦ 1.25, preferably 1.02 ≦ d _N / b _S ≦ 1.10, and particularly preferably 1 , 03 ≤ d _N / b _S ≤ 1.05 applies. Additionally or alternatively, it is provided that the sliding sleeve at least two over an axial distance d _S having spaced apart internal teeth for rotationally fixed meshing with an external toothing of the drive shaft, wherein the external toothing has an axial width b _A wherein 1.00 ≦ d _S / b _A ≦ 1.50, in particular 1.01 ≦ d _S / b _A ≦ 1.25, preferably 1.02 ≦ d _S / b _A ≦ 1.10 and more preferably 1 , 03 ≤ d _S / b _A ≤ 1.05 applies, and / or the drive shaft at least two over an axial distance d _A having spaced apart external teeth for rotationally fixed meshing with an internal toothing of the sliding sleeve, wherein the internal toothing has an axial width b _s wherein 1.00 ≦ d _A / b _S ≦ 1.50, especially 1.01 ≦ d _A / b _S ≦ 1.25, preferably 1.02 ≦ d _A / b _S ≦ 1.10, and more preferably 1 , 03 ≤ d _A / b _S ≤ 1.05 applies. This makes it possible that the respective tooth of the toothing in the freewheeling position is substantially completely, possibly with some play, positioned within the axial distance d, whereby the rotationally fixed positive connection is canceled.

This makes it possible to support the drive shaft with axially spaced apart bearings and provide the sliding sleeve between the bearings. The actuating actuator for actuating the sliding sleeve need not be positioned between the bearings, but may for example be positioned axially outside the hub, wherein the actuating force applied by the actuating actuator is received by the actuating ring and via the connecting element through the bearing element and / or on the Bearing element can be transmitted past the sliding sleeve. The bearing element can in particular form a sliding surface of a plain bearing, in particular radial plain bearing. Furthermore, it is possible for the bearing element to carry an inner ring or outer ring of a bearing, in particular a ball bearing.

If the sliding sleeve is not to be moved, the cam can spring back from the stop and / or be moved back slightly by the actuating actuator, so that the cam is no longer applied to the stop. Unnecessary friction effects and / or rattling noises can be avoided.

In particular, the holding force that can be applied by the latching device in the drive position and / or in the freewheeling position can be overcome by an actuating actuator for the axial displacement of the sliding sleeve. As a result, it is not necessary for the actuation actuator to apply a holding force to the sliding sleeve after reaching the drive position and / or the freewheeling position in order to hold the sliding sleeve in the desired position and / or to press against an axial stop.
