Embodiment Construction

[0029] figure 1 A disc brake 1 with an electromechanical actuator 2 is shown, wherein the electromechanical actuator 2 has an actuator housing 5 . The electromechanical actuator 2 is flanged to the disc brake 1 along the axial axis A. The disc brake 1 has two brake linings 4 , 4 a , which are held against radial dropout by means of a hold-down bracket 3 . Furthermore, the disc brake 1 is subdivided into a brake carrier 40 for accommodating the brake linings 4, 4a and a brake caliper 41, wherein the brake caliper 41 is axially slidable via two guide pins 42, 42a. The way is supported on the brake bracket 40. During the braking process, the electromechanical actuator 2 via the brake linings 4, 4a, pressure pieces not shown and with Figure 2a Turn the lever 7 shown in to clamp the brake disc 46 ( figure 2 ).

[0030] figure 2 shows in detail according to figure 1How the electromechanical actuator 2 is constructed. A cam disk 10 is arranged within the electromechanical ...

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 avehicle 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 tappetmay 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 ofthe 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 discand the housing of the electromechanical actuator.

Description

technical field [0001] The invention relates to a disc brake with an electromechanical actuator for a vehicle, in particular for a commercial vehicle, the disc brake comprising: a brake disc of the vehicle, a brake carrier and a brake caliper, the disc brake being used for The brake disc is clamped with the aid of the brake linings. The electromechanical actuator comprises: a motor, a cam disk configured as a force transmission device, and a tappet configured as an adjusting unit. Background technique [0002] Electromechanical actuators for clamping brake linings for disc brakes are sufficiently known. The adjustment unit is electrically driven by a motor, which is coupled to the adjustment unit via a force transmission device. The force transmission device may be a cam disc, which converts the rotational motion of the motor into a translational motion. The translational movement, also referred to as linear movement, is transmitted to the rotary rod of the disc brake by ...
