Abstract

A roll stabilizer of a motor vehicle including a back (1,9) and legs (3, 14, 15) arranged at opposite ends of the back (1, 9), at an angle in reference to the back (1,9) and with a suspension force (Fz) being transmitted into the ends of the legs facing away from the back (1, 9) to torsion the back (1, 9), and a force sensor (22) is provided to determine the suspension force (Fz).

Claims

1. A roll stabilizer of a motor vehicle comprising a back (1, 9) and legs (3, 14, 15) arranged at opposite ends of the back (1, 9), angled in reference to the back (1, 9) and with a suspension force (Fz) adapted to be transmitted to ends of the legs (1, 9) facing away from the back (1, 9) to torsion the back (1, 9), wherein a force sensor (22) is provided to determine the suspension force (Fz).

2. The stabilizer according to claim 1, wherein a pendulum rod (4, 16, 17) is supported in an articulate fashion at each of the ends of the legs, with the suspension force (Fz) being guided through the pendulum rod (4, 16, 17).

3. The pendulum stabilizer according to claim 2, wherein the force sensor (22) is arranged at the pendulum rod (4, 16, 17).

4. The pendulum stabilizer according to claim 2, wherein the pendulum rod (4, 16, 17) is supported via a connection element at the leg (3, 14, 15) of the stabilizer with the force sensor (22) being arranged at the connection element.

5. The pendulum stabilizer according to claim 2, wherein the pendulum rod (4, 16, 17) is supported via a ball joint (5, 6, 18, 19, 20, 21), with the force sensor being arranged at the ball joint (5, 6, 18, 19, 20, 21).

6. The pendulum stabilizer according to claim 2, wherein the force sensor (22) is connected parallel to the pendulum rod (4, 16, 17) with an elastic deformation of the pendulum rod (4, 16, 17) developing under the suspension force (Fz) being detected by the force sensor (22).

7. The pendulum stabilizer according to claim 2, wherein the force sensor (22) is connected serially in reference to the pendulum rod (4, 16, 17), with the force sensor (22) supporting the suspension force (Fz).

8. The stabilizer according to claim 1, in which the force sensor (22) is embodied as a spring bellows—

force sensor.

9. The stabilizer according to claim 1, in which the force sensor (22) is embodied as a membrane force sensor.

10. The stabilizer according to claim 1, in which the force sensor (22) is embodied as a Piezo-force sensor.
