Abstract

A wheel module for a vehicle, in particular for an electric motorcycle or electric scooter, includes a wheel axle and a wheel. The wheel having a wheel rim and said wheel rim being rotatably mounted on the wheel axle; and including a brake device for the wheel. The brake device having a brake pad and a brake disc for co-operating with the brake pad, said brake disc being axially movable in order to brake the wheel.

First claim

The invention claimed is:

1. A wheel module for a vehicle, comprising:
a wheel axle and a wheel, the wheel comprising a wheel rim and said wheel rim being rotatably mounted on the wheel axle,
and a brake device for the wheel, the brake device comprising a brake pad and a brake disc for cooperating with the brake pad,
wherein
the brake disc is axially movable in order to brake the wheel, and
the brake pad is arranged directly or indirectly on the wheel rim.

2. The wheel module according to claim 1 , wherein the brake device comprises a hydraulic device with an annular hydraulic chamber in a side plan view and with an annular piston for performing a stroke and a return stroke in the hydraulic chamber.

3. The wheel module according to claim 2 , wherein the brake disc is arranged between the annular piston and the brake pad and is axially displaceable by the stroke of the annular piston and can be placed against or pressed against the brake pad.

4. The wheel module according to claim 2 , wherein the hydraulic device is attached to the wheel axle and is arranged concentrically with the wheel rim.

5. The wheel module according to claim 1 , wherein the brake device comprises at least one spring device for generating a restoring force and for applying the restoring force to the brake disc so that the brake disc can be moved axially back into its initial position.

6. The wheel module according to claim 1 , wherein the wheel module has a brake pad carrier for carrying the brake pad.

7. The wheel module according to claim 1 , wherein the brake pad forms a thermal insulation device, wherein the thermal insulation device protects the wheel from waste heat of the brake device.

8. A vehicle having at least one wheel module according to claim 1 .

9. A method for braking a rotating wheel of a wheel module having a brake device of the wheel module according to claim 1 , wherein the brake disc is axially displaced and is applied or pressed against the brake pad.

10. A wheel module for a vehicle, comprising:
a wheel axle;
a wheel having a wheel rim rotatably mounted on the wheel axle; and
a brake device configured for braking the wheel, the brake device comprising a brake pad, a brake pad carrier arranged for carrying the brake pad and a brake disc axially movable in order to brake the wheel, wherein the brake pad carrier is fastened to the wheel rim.

11. The wheel module according to claim 10 , wherein the wheel rim is rotatably mounted on the wheel axle via two rolling bearing devices.

12. A wheel module for a vehicle, comprising:
a wheel axle;
a wheel having a wheel rim rotatably mounted on the wheel axle;
a brake device configured for braking the wheel, the brake device comprising a brake pad, a brake pad carrier arranged for carrying the brake pad and a brake disc axially movable in order to brake the wheel; and
rotation locks designed as axially extending recesses formed in the wheel rim and the brake pad carrier, wherein the brake pad carrier is fastened to the wheel rim.
