Abstract: An electromechanical brake actuator (2) includes a housing (1), a first housing part (3) configured as a housing flange for attaching the electromechanical brake actuator (2) to a disc brake (38), a second housing part (4) for receiving a drive (6), a third housing part (5) arranged between the first housing part (3) and the second housing part (4) and connected to the first housing part (3) and the second housing part (4), a motor (37), a gearbox (7), and a tappet (9) or a spindle for actuating a disc brake (38). The housing (1) is an aluminum die-cast formed part. The first housing part (3) and the second housing part (4) have planar contact surfaces (34, 34a) configured to receive plates of a two-plate die-casting machine during the forming process of the housing (1).

Abstract: 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.
