Abstract

In human-powered vehicles, e.g., bicycles, etc., it is customary to use drum brakes, disc brakes or shoe brakes. Each of the braking systems has different advantages in terms of braking effect, system costs, ease of maintenance, etc. A brake unit with a modified structure for a vehicle is provided. For this purpose, a brake unit 14 for a vehicle 1 is disclosed, having a housing 15, having a brake body device 23, wherein the brake body device 23 supports a stationary brake partner of a brake apparatus 12 for the vehicle 1, wherein the housing 15 and/or the brake body device 23 defines a main axis H, having an actuator for moving the brake body device relative to the housing 15 in order to generate a braking force, wherein the stationary brake partner is formed as a brake disc 13.

First claim

The invention claimed is:

1. A brake unit for a vehicle, the brake unit comprising:
a housing;
a brake body device that supports a stationary brake partner of a brake apparatus for the vehicle, the brake body device being disposed at least partially radially outward of the housing;
at least one of the housing or the brake body device defining a main axis;
an actuator for moving the brake body device relative to the housing in order to generate a braking force, wherein the actuator is configured for axial movement of the brake body device; and
the stationary brake partner is formed as a brake disc.

2. The brake unit according to claim 1 , wherein the brake disc is formed from metal or ceramic.

3. The brake unit according to claim 1 , wherein the brake disc provides a braking surface, the braking surface is formed as at least one of a circular ring surface or extends continuously in a direction of rotation to the main axis.

4. The brake unit according to claim 1 , wherein the actuator comprises a hydraulic unit, the hydraulic unit has an annular space and an annular piston, and the annular space and the annular piston are formed circumferentially to the main axis.

5. A wheel module for a vehicle, the wheel module comprising the brake unit according to claim 1 .

6. The wheel module according to claim 5 , further comprising a wheel, and a rotating brake partner is non-rotatably connected to the wheel.

7. The wheel module according to claim 6 , wherein the rotating brake partner is formed as a brake pad.

8. The wheel module according to claim 6 , further comprising a drive device arranged in the wheel.

9. A vehicle comprising the brake unit according to claim 1 , wherein the vehicle comprises an electric motorcycle or an electric scooter.

10. The wheel module according to claim 8 , wherein the drive device is arranged in a wheel rim of the wheel.

11. A brake unit for a vehicle, the brake unit comprising:
a housing;
a brake body that supports a stationary brake partner comprising a brake disc;
at least one of the housing or the brake body defining a main axis;
an actuator for moving the brake body relative to the housing in order to generate a braking force; and
a rotating brake partner configured to be non-rotatably connected to a wheel of the vehicle;
wherein a cylindrically-shaped receiving section of the housing extends axially through the brake body such that the receiving section is axially aligned with the main axis, and the receiving section is configured for receiving a wheel axle of the wheel.

12. The brake unit according to claim 11 , wherein the brake disc is formed from metal or ceramic.

13. The brake unit according to claim 11 , wherein the brake disc provides a braking surface, the braking surface is formed as at least one of a circular ring surface or extends continuously in a direction of rotation to the main axis.

14. The brake unit according to claim 11 , wherein the actuator is configured for axial movement of the brake body.

15. The brake unit according to claim 14 , wherein the actuator comprises a hydraulic unit, the hydraulic unit has an annular space and an annular piston, and the annular space and the annular piston are formed circumferentially about the main axis.

16. The brake unit according to claim 15 , wherein the receiving section forms an inner wall of the annular space and an outer wall of the housing delimits the annular space radially on the outer side.

17. A wheel module for a vehicle, the wheel module comprising:
a wheel;
a drive device arranged in the wheel, the drive device being an electric motor;
a rotating brake partner non-rotatably connected to the wheel; and
a brake unit comprising:
a housing;
a brake body device that supports a stationary brake partner of a brake apparatus for the vehicle;
at least one of the housing or the brake body device defining a main axis;
an actuator for moving the brake body device relative to the housing in order to generate a braking force; and
the stationary brake partner is formed as a brake disc.

18. The brake unit according to claim 1 , wherein the actuator is integrated into the housing.

19. The brake unit according to claim 11 , wherein the actuator is integrated into the housing.
