Problems solved by technology

[0004] However, these systems, as mentioned above, have the disadvantage that the design has a high complexity, which on the one hand is costly in terms of manufacture and assembly and on the other hand prevents simple maintainability
Significant space requirements for this arrangement due to the large number of components

Embodiment Construction

[0049] figure 1 An electromechanical brake actuator 102 is shown having a housing 104 . The electromechanical brake actuator 102 has an electric motor 106 . The driving torque of the motor 106 is passed through the transmission (see figure 2 ) to the cam disc 108. The cam plate 108 is used to non-linearly transmit the rotational motion of the cam plate 108 to the brake lifter 114 .

[0050] The brake tappet 114 can be deflected, in particular linearly, in the direction of the indicated arrow. At the end of the brake tappet facing the cam disk 108 , the brake tappet 114 has a tappet head 112 . The tappet head 112 surrounds a rolling body 110 , which is supported by means of a bearing 116 . The rolling bodies 110 slide on the periphery of the cam disc 108 . Thus, a transfer of the rotational movement of the cam disc 108 into a linear movement of the brake tappet 114 is achieved. In particular, electromechanical brake actuator 102 can be connected to a brake (not shown) v...

Abstract

The invention relates to an electromechanical brake actuator (102, 202, 302, 402) for a brake, in particular a commercial vehicle disc brake, having an electric motor (106, 206) for generating a drivetorque, a rotatably mounted cam (108, 208, 308, 408) which is operatively connected to the electric motor (106, 206), and a brake plunger (114, 214, 314) which is movable along a plunger axis to actuate a brake lever (358) of the brake (368). According to the invention, the cam (108, 208, 308, 408) and the brake plunger (114, 214, 314) have contact faces which bear against each other and slide orroll on each other for the direct transmission of the drive torque between the cam (108, 208, 308, 408) and the brake plunger (114, 214, 314).

Description

technical field [0001] The invention relates to an electromechanical brake actuator for brakes, in particular commercial vehicle disc brakes, which has an electric motor for generating a drive torque, a rotationally movable device operatively connected to the electric motor A supported cam disc and a brake tappet movable along the tappet axis for actuating the brake lever of the brake. Background technique [0002] Electromechanical brake actuators are generally known in the motor vehicle field, in particular in the commercial vehicle field. Thus, eg AT 516801 A2 discloses such an electromechanical brake actuator. The goal is usually to operate the brake with electrical energy. The challenge is to achieve sufficiently short brake actuation times and at the same time achieve the desired braking power with the smallest possible and energy-efficient electric motor. For this purpose, AT 516801 A2 proposes an electromechanical actuator which has two transmission links. A coup...
