Abstract
A centering mechanism with a brake piston of a disk brake of a motor vehicle, with a spindle extending into a cavity in the brake piston, has dimensions that prevent a force equilibrium of a nut-spindle assembly moved completely out of the vertical position. A force vector of the gravitational force on the nut-spindle assembly extends within a contact surface between a nut and the brake piston. Thus, the brake piston can be easily assembled with the nut-spindle assembly.
Claims6
A centering mechanism comprising:
- a brake piston of a disk brake of a motor vehicle;
- and
- a nut/spindle module comprising a spindle that projects into a recess of the brake piston and a nut that is screwed onto the spindle;
- wherein the nut has a nut support surface and the brake piston has a brake support surface that lies opposite the nut support surface;
- wherein in the case of a vertical arrangement, with the brake piston below the spindle and the nut, a force equilibrium is avoided when the nut/spindle module has been moved out of the vertical position;
- and
- wherein the nut/spindle module has a center of gravity and in the case of the vertical arrangement, the center of gravity of the nut/spindle module moved out of the vertical position is distanced from a contact plane of the nut and brake support surfaces in an amount less than half the diameter of the contact plane of the nut and brake support surfaces.
