Definitions

• the invention relates to a vehicle axle, in particular torsion beam axle for an electric vehicle, comprising at least one trailing arm on which a wheel-proximate drive unit is arranged with an electric machine and a gear unit, wherein the radnahe drive unit has at least one supply line and with at least one damper.
• the invention also relates to a motor vehicle with at least one vehicle axle.
• Such vehicle axles are used in electric vehicles and serve both for suspending the respective wheels of the electric vehicle and for driving them.
• the vehicle axle is supported, inter alia, by means of at least one damper on the body for damping the compression movement of the wheel or the wheels of the axle.
• at least one supply line is usually arranged in order to provide the electrical machine of the drive unit close to the wheel with electrical energy, for example from accumulators, which are located at other positions within the electric vehicle.
• An object of the present invention is therefore to provide a vehicle axle, which allows improved damping of the vehicle axle with the drive unit close to the wheel and at the same time a longer service life of the drive unit close to the wheel.
• the invention solves the problem in a vehicle axle, in particular a torsion beam axle for an electric vehicle, comprising at least one trailing arm on which a radnahe drive unit is arranged with an electric machine and a transmission unit, wherein the radnahe drive unit has at least one supply line and with at least one damper in that the wheel-near drive unit is at least partially designed as a trailing arm and that the damping fer is connected with at least one side at least one-sided with the drive unit and with the at least other side with a body of the electric vehicle is connectable.
• the invention also achieves the object in a motor vehicle having at least one vehicle axle in that the vehicle axle is designed according to at least one of claims 1 to 15.
• the advantage achieved by the invention is that an improved power transmission from the vehicle axle to the body by means of the damper and thus an improved damping of the electric vehicle can be provided as a whole.
• the vehicle axle is simple in construction and can therefore be carried out inexpensively.
• the damper is fixed by means of a conical connection to the drive unit in the region of the trailing arm.
• the screw can be screwed with a higher tightening torque. This improves the connection of the damper to the wheel-near drive unit: More force can be transmitted from the wheel-near drive unit by compression movements of the wheel on the damper. This achieves an improved damping effect.
• the damper is fixed by means of a screw on the drive unit.
• a cost-effective and at the same time extremely simple connection of the damper to the near-wheel drive unit is possible.
• the drive unit has a through hole for receiving a screw of the screw connection. If a through hole is arranged, a maximum screw depth for the screw of the screw is provided. In this way, a particularly reliable screw is possible.
• a seal is arranged in the region of the through bore.

• housing half is essentially a two-part housing to understand, the housing halves do not necessarily have the same size, dimensions, etc. must have.
• the damper can be fixed by means of the screw to both the wheel-side housing half and to the caliper-side housing half. Due to the through hole in the longitudinal arm side housing half this is also form-fitting and non-positively connected to the wheel-side housing half. An additional definition of the wheel-side and longitudinal arm side housing half in the damper is thereby avoided.
• additional fasteners, such as holes, etc in the two-part housing of the wheel near drive unit are largely avoided.
• the through hole is arranged in both housing halves and a screw of the screw connection is fixed by means of a nut in the region of the wheel-side housing half.
• a different material can be used for the screw as for the housing of the gear unit and / or the drive unit:
• a tightening torque of the screw must then not be adapted to the material of the housing of the wheel-side drive unit, but the material from which the screw and the mother are made.
• a higher torque can be realized, for example, by screw and nut made of steel, the housing for weight saving made of aluminum.
• the at least two-part housing is made of aluminum. In this way, the weight of the near-wheel drive unit can be reduced without reducing the rigidity and / or strength of the housing.
• the damper is set in two sections on the drive unit. In this way, a more reliable determination of the damper on the wheel near drive unit is possible and the forces acting on the wheel near drive unit by compression movements of the wheel can be more effectively damped by the damper.
• a spring plate is arranged on the electric machine in the drive unit and the damper on the one hand on the spring plate on the other hand fixed to the wheel-side housing half.
• At least one fixing means for fixing the at least one supply line in the upper region of the trailing arm is arranged.
• a supply line for example, cables, fluid-tight pipes, cables, etc are used.
• the arrangement of the fixing element in the upper region of the trailing arm for the at least one supply line is provided in this area by the slight movement of the trailing arm relative to the body of the vehicle no or minimal mechanical stress on the supply line by bending or train. The service life of the supply lines is thus increased.
• the fixing element comprises a bracket and / or a clamp.
• the at least one supply line can be determined extremely inexpensive, whereas by means of a clamp a particularly simple and reliable determination of at least one supply line is possible.
• the fixing element comprises a screw and / or clip connection.
• a particularly cost-effective and at the same time easily detachable connection is provided. In maintenance trap this can be opened or solved and the at least one supply line to be replaced.
• a guide element in particular a guide groove, arranged to guide the at least one supply line.
• the assembly of the at least one supply line for the radnahe drive unit is further simplified.
• an unwanted rubbing is thus avoided when several supply lines move through the up and down movement of the drive unit close to the wheel against each other and / or at least partially rotate. These are held by the guide member substantially in their respective predetermined position.
• the guide element is integrally formed on the trailing arm.
• the guide element can be produced extremely inexpensively together with the trailing arm. Additional complex manufacturing processes for the guide element and / or its determination on the trailing arm are thus avoided.

Finally, the supply lines 9 are still at least partially fixed by means of guide grooves 7c on the upper side of the trailing arm 3.
• the guide grooves 7c serve, on the one hand, to prevent the supply lines 9 from rubbing against each other during a compression movement of the torsion-beam axle 1, thus damaging the supply lines 9.
• the guide groove 7c also allows for easier mounting of the bracket 8, since the supply lines 9 are held in predetermined positions and can then be set more easily by means of the bracket 8.
