ELECTROMECHANICAL ACTUATOR FOR A BRAKE

摘要

An electromechanical actuator for a vehicle brake, the actuator comprising first and second portions 8 and 9 that are separable. The first portion 8 includes an electric motor 5 and connection structure 15 for connecting the actuator to an external control structure 4. The second portion 9 including a slidable pusher 6, the second portion 9 also including measurement structure 21. The first portion 8 includes a first antenna 14 connected to the connection structure 15, and the second portion 9 includes a second antenna 22 connected to the measurement structure 21, the two antennas 14, 22 being arranged to be electromagnetically coupled together when the first portion 8 and the second portion 9 are coupled together, so as to enable electrical signals to be transferred between the measurement structure 21 and the connection structure 15.

1. An electromechanical actuator for a vehicle brake, the actuator comprising a first portion (8) and a second portion (9) that are separable, the first portion (8) having an electric motor (5) and connection means (15) for connecting the actuator to external control means (4), and the second portion (9) including a pusher (6) mounted to slide so as to project from the second portion (9) through an opening (30) formed therein, the first portion (8) and the second portion (9) being coupled together so that the motor (5) co-operates with the pusher (6) to cause the pusher (6) to move in response to drive from the motor (5), the second portion (9) further including measurement means (21) for measuring an operating characteristic of the actuator; the actuator being characterized in that the first portion (8) includes a first antenna (14) connected to the connection means (15), and the second portion (9) includes a second antenna (22) connected to the measurement means (21), the two antennas (14, 22) being arranged so as to be electromagnetically coupled together when the first portion (8) and the second portion (9) are coupled together, so as to enable electrical signals to be transferred between the measurement means (21) and the connection means (15).
