A disc brake () includes a brake disc (), a brake caliper (), two brake pads (') that are movably guided on the brake caliper (), a retainer spring (′) on each brake pad (′), a retainer bracket (-) for pre-tensioning the retainer springs (′) in relation to the respective brake pad (′), and an expander spring (′) that applies an expansion force between the brake pads (′) and diverging the brake pads (′). The ends of the expander spring (′) may bear in each case directly on one of the retainer springs (′). The disc brake () may have a loss prevention device that is operatively connected to the expander spring (′) such that the expander spring (′), in the absence of the expansion force, is held on the disc brake ().

Disc brake for a motor vehicle

The present disclosure relates to a disc brake having an electromechanical actuator for vehicles, in particular for utility vehicles, comprising a brake disc, a brake carrier and a brake caliper of a vehicle for applying the brake disc by means of brake linings. Current tests have shown that the tappet after assembly is not fixed correctly in a housing of the electromechanical actuator. The tappet may after positioning fall out of the rotary lever, which results in the force transmission for applying the brake disc being interrupted and the brake disc not being able to be applied. An object of the present disclosure is to overcome the problems from the prior art and to provide a disc brake with an electromechanical actuator which reduces or even prevents damage to the tappet, the cam disc and the housing of the electromechanical actuator.

Disc brake having an electromechanical actuator

A disc brake for commercial vehicle includes a brake caliper and brake pads for clamping the brake disc. The brake caliper has a first inside space with an opening on a side facing the brake disc for receiving a clamping device, and the brake caliper has a second inside space for receiving the brake disc. The brake caliper and brake pads have advantages in terms of installation space and is lightweight and reduces production costs. The brake caliper includes clamping-side lugs and reaction-side lugs. The lugs on each side define a channel for receiving the brake pads for each side. The brake pads include supporting surfaces and bearing surfaces on their perimeter that correspond to the arrangement of the lugs. The lugs on the clamping side define an L-shape. The axial length of supporting surfaces of the clamping side brake pad is shorter than that of the clamping-side lugs.
