Abstract

Split roll stabilizer of a motor vehicle, between the two stabilizer parts ( 2 a ) of which an actuator ( 1 ) for a torsion of the stabilizer parts ( 2 a ) can be effectively disposed, a sensor ( 11 ) for determining the torsional moment acting in the stabilizer parts ( 2 a ) being provided.

Claims (6)

1. A split roll stabilizer of a motor vehicle, comprising two stabilizer parts adapted to receive an actuator actively arranged therebetween for torsion of the stabilizer parts, and a sensor that determines a torsional moment acting in the stabilizer parts, the sensor includes a magnetically coded primary sensor arranged on one of the stabilizer parts, and a magnetic field sensor that converts changes in a magnetic field of the primary sensor into an electrical signal as a secondary sensor, and the primary sensor is formed by a section of the one of the stabilizer parts that is formed from ferromagnetic material and is coded magnetically, and the active torsional moment is introduced into said section.

2. The split roll stabilizer according to claim 1 , wherein the one of the stabilizer parts is supported for rotation by a stabilizer bearing, and the primary sensor is arranged between an end of the one of the stabilizer parts facing the actuator and the stabilizer bearing.

3. The split roll stabilizer according to claim 1 , wherein both of the stabilizer parts are supported for rotation by stabilizer bearings, and there are two of the primary sensors, with each one of the primary sensors being arranged between an end of the stabilizer parts facing the actuator and the stabilizer bearing.

4. A split roll stabilizer of a motor vehicle, comprising two stabilizer parts adapted to receive an actuator actively arranged therebetween for torsion of the stabilizer parts, and a sensor that determines a torsional moment acting in the stabilizer parts, the sensor includes a magnetically coded primary sensor arranged on one of the stabilizer parts, and a magnetic field sensor that converts changes in a magnetic field of the primary sensor into an electrical signal as a secondary sensor, and the primary sensor is connected parallel to the one of the stabilizer parts for detecting a measurement torque, and the measurement torque is dependent on a torsion of the stabilizer part.

5. The split roll stabilizer according to claim 4 , wherein the primary sensor is formed by a sleeve arranged on the one of the stabilizer parts.

6. The split roll stabilizer according to claim 5 , wherein an end of the one of the stabilizer parts facing the actuator is locked in rotation with a flange connected to the actuator, and the sleeve is locked in rotation at one end with the flange and at the other end with the stabilizer part.
