Disc brake, in particular for utility vehicles
A disc brake for utility vehicles includes a brake disc, a first brake lining on a first side of the brake disc and a second brake lining on a second side of the brake disc opposite the first side. A spreading device is also provided which generates a force that moves the first and the second brake lining away from one another.
1. A disc brake for commercial vehicles, comprising:
a brake disc ( 13 );
a first brake lining ( 14 ) on a first side of the brake disc ( 13 );
a second brake lining ( 16 ) on a second side of the brake disc ( 13 ) opposite the first side;
a brake carrier ( 10 );
a brake caliper ( 12 ) mounted in a floating manner; and
a restoring device ( 52 ), wherein the restoring device ( 52 ) is configured to generate a force to move the brake caliper ( 12 ) in relation to the brake carrier ( 10 ) in the direction opposite to a direction of movement of the brake caliper ( 12 ),
wherein the brake caliper ( 12 ) is mounted on a bolt ( 54 ) displaceably in relation to the brake carrier ( 10 ), and the restoring device ( 52 ) includes a spring arranged entirely inside the bolt.
2. The disc brake as claimed in claim 1 , wherein the restoring device ( 52 ) is on the second side of the brake disc ( 13 ).
3. The disc brake as claimed in claim 1 , wherein the restoring device ( 52 ) has at least one elastic element.
4. The disc brake as claimed in claim 1 , wherein the restoring device ( 52 ) has a compression spring ( 58 ), the compression spring ( 58 ) being supported on a first stop ( 60 ) on a side facing the brake disc, wherein the first stop ( 60 ) is coupled axially to the brake caliper ( 12 ) at least in terms of a movement toward the brake disc ( 13 ), and
the compression spring ( 58 ) being supported on a second stop ( 64 ) on a side facing away from the brake disc, wherein the second stop ( 64 ) is coupled axially to the bolt ( 54 ) at least in terms of a movement away from the brake disc ( 13 ).
5. The disc brake as claimed in claim 4 , wherein the first stop ( 60 ) is formed on a cup ( 62 ) or the second stop ( 64 ) is formed on a disc.
6. The disc brake as claimed in claim 5 , wherein the cup ( 62 ) has at least one through-opening ( 70 ) through which a lug ( 68 ) of the disc extends.
7. The disc brake as claimed in claim 3 , wherein the at least one elastic element is a compression spring ( 58 ).
8. The disc brake as claimed in claim 4 , wherein the first stop ( 60 ) is formed on a cup ( 62 ) and the second stop ( 64 ) is formed on a disc.
