A brake actuator (') includes a casing (), an electric motor for providing a driving torque, a cam disc () rotatably mounted to the casing () and operatively coupled to the electric motor, and a push rod () received in the casing (), and configured to reciprocate in a longitudinal direction () between a retracted position () and an extended position (). The push rod () and the cam disc () are operatively coupled such that a rotational movement of the cam disc () causes a linear movement of the push rod. A guiding member (), in particular a bushing, is mounted to the casing (), wherein the guiding member () guides the movement of the push rod () in the longitudinal direction ().

Brake actuator, in particular electromechanical brake actuator of a commercial 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

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