Abstract

The invention relates to an operating apparatus for a brake, having an actuator unit with a linearly mobile actuator element, an actuating unit with a linearly mobile actuating element by means of which a braking element can be moved relative to a brake disc or a brake drum, and a transmission unit for transmitting a force from the actuator element to the actuating element. The transmission unit has a deflection device by means of which the force which is transmitted from the actuator element to the actuating element can be deflected from a first direction into a second direction.

First claim

a transmission unit configured to transmit a force from the first actuator element to the second actuating element;
wherein the transmission unit has a deflection device configured to deflect a force transmitted from the first actuator element to the second actuating element from a first direction into a second direction;
wherein the deflection device has a deflection element which is mounted rotatably about a stationary axis of rotation with at least two coupling devices which are displaced relative to each other in the direction of rotation for coupling respective force transmission elements; and
wherein distances between the coupling devices and the axis of rotation of the deflection element are different.

2. The operating apparatus of claim 1 , wherein the coupling devices are displaced relative to each other at an angle of 20° to 120° in a circumferential direction.

3. The operating apparatus of claim 2 , wherein the coupling devices are displaced relative to each other at an angle of 75° to 105° in the circumferential direction.

4. The operating apparatus of claim 2 , wherein the rotatably mounted deflection element has at least two radially extending pivoted levers on which the coupling devices are formed.

5. The operating apparatus of claim 4 , wherein the at least one of the coupling devices comprises as a hinge connection.

6. The operating apparatus of claim 5 , wherein the at least one of the coupling devices has at least one of a sliding surface and a rolling surface, along which a force transmission element is movable in a radial direction.

7. The operating apparatus of claim 6 , wherein the second actuating unit and the transmission unit are accommodated in a common housing.

8. The operating apparatus of claim 7 further comprising:
a fastening device that is configured to allow the operating apparatus to be fastened to at least one of an axle element in different rotational positions about a longitudinal axis of the second actuating element and a wheel axle of an axle element of a wheel to be braked.

9. The operating apparatus of claim 8 , wherein the deflection device causes a deflection of the force in a plane, which is spanned by a wheel axle of an axle element of a wheel to be braked and a perpendicular to the wheel axle.

10. The operating apparatus of claim 9 , further comprising:
a first coupling device onto which acts at least one of the first actuator element and a force transmission element connected thereto.

11. The operating apparatus of claim 10 , wherein at least one of the first actuator element and the second actuating element has a linearly mobile base body and a transmission head pivotably mounted thereon.

12. The operating apparatus of claim 1 , wherein the rotatably mounted deflection element has at least two radially extending pivoted levers on which the coupling devices are formed.
