Problems solved by technology

However, in some vehicle control systems, such as brake systems in particular, this has the disadvantage that, when using such an electric motor, in addition to at least three connections for the power electronics, there must also be a connectors and connections for the sensor signal of the sensor, which results in additional power consumption

Embodiment Construction

[0016] The single FIGURE shows a simplified sectional illustration of an actuator arrangement 1 for a brake system of a motor vehicle, which is not shown here in greater detail. The actuator device 1 has a housing 2 in which a hydraulic pump 3 is arranged as load. The hydraulic pump 3 has a pump impeller 4 which is arranged in a shaft 5 mounted rotatably in the housing 2 . If the shaft 5 is driven, the pump wheel 4 pumps hydraulic medium in the direction of the wheel brakes of the brake system. In order to distribute the hydraulic pressure generated by the hydraulic pump 3 in a targeted manner to the wheel brakes, a plurality of actuatable solenoid valves 6 are also arranged in the housing, of which only the energizable coils of the solenoid valves are shown here. By actuating or actuating the valves 6 , hydraulic medium is supplied to the individual wheel brakes in a targeted manner, so that the pressure is built up or reduced in a targeted manner.

Abstract

The invention relates to an actuator device (1) for a braking system of a vehicle, in particular a motor vehicle, said actuator device comprising at least one electronically commutated electric motor (7), the electric motor There is a rotor (9) which is arranged in a rotationally fixed manner on a rotatably mounted shaft (5), said actuator device also comprising at least one rotational angle sensor for detecting the rotational position of said rotor (9) ( 13) wherein said shaft (5) is connected to at least one load (3) driven by an electric motor (7). It is provided that an angle of rotation sensor ( 13 ) is assigned to the end ( 16 ) of the shaft ( 5 ) associated with the load ( 3 ).

Description

technical field [0001] The invention relates to an actuator device for a braking system of a vehicle, in particular a motor vehicle, the actuator device comprising at least one electronically commutated electric motor having a rotor fixed torsionally Arranged on a rotatably mounted shaft, the actuator device further comprises at least one rotational angle sensor for detecting the rotational position of the rotor, wherein the shaft is connected to at least one load driven by the electric motor. [0002] Furthermore, the invention relates to a brake system for a vehicle, in particular a motor vehicle, having at least one wheel brake and at least one actuator device for actuating the wheel brake. Background technique [0003] Actuator arrangements for motor vehicles are known in particular in connection with hydraulic brake systems in which the braking force is set via hydraulic pressure. For this purpose, such brake systems usually have an actuator, in particular a hydraulic ...
