Abstract

Claims (32)

1 . A drum brake, comprising:

at least one brake shoe;

a carrier connected to a supporting bearing for the at least one brake shoe; and

a deformation sensor configured to determine a deformation of the carrier,

wherein the carrier has a lower stiffness than the supporting bearing, and/or

wherein the carrier has an intended deformation region that has a lower stiffness than the supporting bearing.

2 . The drum brake as claimed in claim 1 , wherein the carrier and the supporting bearing are formed separately from each other.

3 . The drum brake as claimed in claim 1 , wherein the carrier has at least one material weakness.

4 . The drum brake as claimed in claim 3 , wherein the at least one material weakness is a recess.

5 . The drum brake as claimed in claim 1 , wherein the carrier has a trapezoidal design.

6 . The drum brake as claimed in claim 5 , wherein the trapezoidal carrier has a first base side and a second base side which run parallel to each other, wherein the first base side is longer than the second base side, and wherein the two base sides are connected to each other by two leg sides.

7 . The drum brake as claimed in claim 1 , wherein the supporting bearing extends transversely to a plane in which the carrier extends.

8 . The drum brake as claimed in claim 1 , wherein one of:

the carrier comprises a deformation sensor carrier configured to accommodate the deformation sensor, or

the carrier comprises a receptacle configured to accommodate the deformation sensor.

9 . The drum brake as claimed in claim 8 , wherein the deformation sensor or the deformation sensor carrier is arranged in or on an intended deformation region.

10 . The drum brake as claimed in claim 1 , wherein the deformation sensor is arranged spaced apart from the carrier.

11 . The drum brake as claimed in claim 1 , wherein the carrier is arranged in such that a supporting force can be transmitted from the at least one brake shoe to the carrier by the supporting bearing.

12 . A brake system comprising:

at least one drum brake, comprising:

at least one brake shoe;

a carrier connected to a supporting bearing for the at least one brake shoe; and

a deformation sensor configured to determine a deformation of the carrier,

wherein the carrier has a lower stiffness than the supporting bearing, and/or

wherein the carrier has an intended deformation region that has a lower stiffness than the supporting bearing.

13 . A vehicle comprising:

at least one drum brake, comprising:

at least one brake shoe;

a carrier connected to a supporting bearing for the at least one brake shoe; and

a deformation sensor configured to determine a deformation of the carrier,

wherein the carrier has a lower stiffness than the supporting bearing, and/or

wherein the carrier has an intended deformation region that has a lower stiffness than the supporting bearing.
