Brake pad of a vehicle brake, vehicle brake and method for assembling a vehicle brake

A brake pad (40) of a vehicle brake (1), in particular of a disc brake of a commercial vehicle, the brake pad (40) comprising:

• a brake pad carrier (30) having a support surface (32),
• a friction lining (40a) attached to the support surface (32)
• a recess (38) extending from the support surface (32) in an axial direction, and
• a wear indication device (34) arranged at least partially inside the recess (38),
• wherein the brake pad carrier (30) includes a clamping member (39, 39′) resting against an inner wall of the recess (38), wherein the clamping member (39, 39′) applies a clamping force on the wear indication device (34) in a radial direction;
• wherein the clamping member (39, 39′) comprises a spring;
• wherein the clamping member (39′) is a star washer arranged around the shaft portion (342) of the wear indication device (34, 34′) or the clamping member (39′) is a slotted ring, in the form of an undulated spring band material, arranged around the shaft portion (342, 342′) of the wear indication device (34, 34′).

A vehicle brake (1), in particular disc brake of a commercial vehicle, the vehicle brake (1) comprising:

• a brake disc,
• a brake pad (40) having a friction lining (40a), wherein the friction lining (40a) is configured to bear against the brake disc during braking, and a brake pad carrier (30) configured to carry the friction lining (40a) proximate to the brake disc, the brake pad carrier (30) comprising:
• a support surface (32) for carrying the brake pad (40),
• a recess (38) extending into the support surface (32) in an axial direction (A), and
• a wear indication device (34, 34′) arranged at least partially inside the recess (38),
• wherein the brake pad carrier (30) includes a clamping member (39, 39′) resting against an inner wall of the recess (38), wherein the clamping member (39, 39′) applies a clamping force on the wear indication device (34) in a radial direction;
• wherein the clamping force applied in a radial direction provides a frictional clamping force, wherein the frictional clamping force permits an axial retraction of the wear indication device out of the recess when the frictional clamping force is overcome.

A method for assembling a vehicle brake (1), in particular a disc brake of a commercial vehicle, the method comprising the steps of:

• arranging a clamping member (39, 39′) around a wear indication device (34, 34′), wherein the wear indication device includes a shaft portion (342, 342′) thereof, wherein the clamping member is arranged around the shaft portion (342, 342′) of the wear indication device (34, 34′), wherein the clamping member (39, 39′) is at least partly received in a circumferential groove (346) of the wear indication device (34, 34′),
• arranging the wear indication device (34, 34′) and the clamping member (39, 39′) adjacent a recess (38) of a brake pad carrier (30), and
• coupling the wear indication device (34, 34′) and the brake pad carrier (30) by a linear movement of the wear indication device (34, 34′) and the clamping member (39, 39′) towards the recess (38) and along an axial direction (A) of the recess (38), such that the wear indication device (34, 34′) is at least partly received in the recess (38) and the clamping member (39, 39′) rests against an inner wall of the recess (38) thereby applying a clamping force on the wear indication device (34, 34′) in a radial direction wherein the clamping force applied in a radial direction provides a frictional clamping force;
• and
• retracting the wear indication device out of the recess by overcoming the frictional clamping force in response to a pulling force applied on the wear indication device.
