Abstract

A disc brake ( 1 ) for a utility vehicle includes a brake disc ( 19 ), a brake caliper ( 2 ) which surrounds the brake disc ( 19 ), an application-side brake lining ( 3 ), a rim-side brake lining ( 3 a ) and an application-side application device ( 4 ) which is arranged in the brake caliper ( 2 ). The application device ( 4 ) has at least one adjustment spindle ( 5 ) and a pressure plate ( 6 ) that is arranged axially between the adjustment spindle ( 5 ) and the application-side brake lining ( 3 ). A plain bearing element ( 7 ) is arranged between the pressure plate ( 6 ) and the adjustment spindle ( 4 ).

Claims (16)

1. A disc brake ( 1 ) for a utility vehicle comprising:

a brake disc ( 19 ),

a brake caliper ( 2 ) surrounding the brake disc ( 19 ),

an application-side brake lining ( 3 ), a rim-side brake lining ( 3 a ), and an application-side application device ( 4 ) arranged in the brake caliper ( 2 ),

wherein the application device ( 4 ) includes at least one adjustment spindle ( 5 ) and a pressure plate ( 6 ), wherein the pressure plate ( 6 ) is arranged axially between the adjustment spindle ( 5 ) and the application-side brake lining ( 3 ),

wherein a plain bearing element ( 7 ) is arranged between the pressure plate ( 6 ) and the adjustment spindle ( 4 );

wherein the plain bearing element ( 7 ) is arranged axially on a pressure plate pin ( 13 ) of the pressure plate ( 6 );

wherein the plain bearing element ( 7 ) has at least one stamping ( 8 , 8 a , 8 b );

wherein the plain bearing element ( 7 ) has a cylindrical shape extending axially along the pressure plate pin ( 13 ), wherein the at least one stamping ( 8 , 8 a , 8 b ) extends in the axial direction along the cylindrical shape, wherein the at least one stamping is in the form of a corresponding outer projection and inner recess formed in the cylindrical shape.

2. The disc brake ( 1 ) as claimed in claim 1 , wherein the pressure plate ( 6 ) and the plain bearing element ( 7 ) are arranged axially via a pressing operation at an end side ( 10 ) of the adjustment spindle ( 5 ).

3. The disc brake ( 1 ) as claimed in claim 1 , wherein the plain bearing element ( 7 ) includes a plastics material coating ( 11 ) on an inner wall ( 9 ) of the plain bearing element ( 7 ).

4. The disc brake ( 1 ) as claimed in claim 1 , wherein the plain bearing element ( 7 ) has an inner wall ( 9 ) and the inner wall ( 9 ) of the plain bearing element ( 7 ) is constructed in a circular manner.

5. The disc brake ( 1 ) as claimed in claim 1 , wherein the plain bearing element ( 7 ) axially secures the pressure plate ( 6 ) to the adjustment spindle ( 5 ) during a return movement of the adjustment spindle ( 5 ), wherein the return movement runs counter to the direction of the application-side brake lining ( 3 ).

6. The disc brake ( 1 ) as claimed in claim 1 , wherein the plain bearing element ( 7 ) defines a play between the pressure plate ( 6 ) and the adjustment spindle ( 5 ).

7. The disc brake ( 1 ) as claimed in claim 1 , wherein the plain bearing element ( 7 ) is a plain bearing bush ( 7 ).

8. The disc brake ( 1 ) as claimed in claim 1 , wherein the plain bearing element ( 7 ) is formed from a metal material.
