Abstract

An assembly for determining a measurement quantity for a braking force acting on a brake, including a carrier and a brake holder. The aim of the invention is for the assembly to enable precise and reproducible measurements of a measurement quantity characteristic of the braking force. This aim is achieved in that the brake holder is arranged in such a way that the brake holder can be elastically and laterally displaced with respect to the carrier, wherein the brake holder is fastened to the carrier by at least one elastic bending element, wherein a sensor device is provided for determining the displacement distance of the brake holder with respect to the carrier.

First claim

The invention claimed is:

1. An arrangement for determining a measurement variable for a braking force acting on a brake, comprising:
a carrier,
a brake holder, and
a sensor device,
wherein
the brake holder is arranged so as to be elastically and laterally displaceable relative to the carrier, wherein the brake holder is fixed by two elastic bending elements to the carrier, wherein the sensor device determines a displacement travel of the brake holder relative to the carrier, and
wherein the two elastic bending elements are led through openings in the carrier and, on a side averted from the brake holder, are fastened in support elements which are rigidly connected to the carrier.

2. The arrangement as claimed in claim 1 , wherein the carrier is part of a vehicle chassis.

3. The arrangement as claimed in claim 1 , wherein the at least one elastic bending element is inserted into the brake holder.

4. The arrangement as claimed in claim 1 , wherein the sensor device comprises a sensorially active and a sensorially passive element, and wherein one sensor element is rigidly connected in positionally fixed fashion to the carrier or the brake holder, and the other sensor element is connected in positionally fixed fashion to the brake holder or the carrier.

5. The arrangement ( 30 ) as claimed in claim 4 , wherein the sensorially active element is connected in positionally fixed fashion to the carrier and the sensorially passive element is connected in positionally fixed fashion to the brake holder.

6. The arrangement as claimed in claim 4 , wherein the sensorially passive element is received in a solid measure.

7. The arrangement as claimed in claim 4 , wherein the sensorially passive element is a permanent magnet, and wherein the sensorially active element is a magnetoresistive angle measuring element.

8. The arrangement as claimed in claim 4 , wherein the sensorially passive element is an element composed of ferritic material, and wherein the sensorially active element is a coil arrangement.

9. The arrangement as claimed in claim 5 , wherein the sensorially passive element is received in a solid measure.

10. A device for determining a measurement variable for a braking force acting on a disk brake, which is hydraulically actuatable, of a motor vehicle, comprising an arrangement as claimed in claim 1 , furthermore comprising an open-loop control unit and a closed-loop control unit which is connected at the input side to the sensor device and which performs closed-loop braking control on the basis of at least one measurement signal of the sensor device.

11. A disk brake, for a motor vehicle, having an arrangement as claimed in claim 1 .

12. A method for determining a measurement variable for a braking force acting on a hydraulically actuatable disk brake of a motor vehicle, having an arrangement as claimed in claim 1 , wherein a lateral displacement of the brake holder relative to the carrier is measured.

13. An arrangement for determining a measurement variable for a braking force acting on a brake, comprising:
a carrier,
a brake holder, and
a sensor device,
wherein the brake holder is arranged so as to be elastically and laterally displaceable relative to the carrier, wherein the brake holder is fixed by at least one elastic bending element to the carrier, wherein the sensor device determines a displacement travel of the brake holder relative to the carrier, and
wherein the at least one elastic bending element is in each case laterally surrounded by a space into which the at least one elastic binding element is configured to expand in the event of a lateral displacement of the brake holder relative to the carrier.
