Actuators And Stabilizer Bars: Notes
WARNING: This page is about a different car, the 2012 Land Rover Range Rover Sport and 2011 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.
Two stabilizer bars with integral hydraulic actuators are used for the Dynamic Response system. The actuators apply a hydraulically generated force or rotational torque to the stabilizer bar to oppose lateral forces caused by the vehicle cornering.
| Item Number | Description |
|---|---|
| 1 | Air bleed ports |
| 2 | Piston |
| 3 | Ball screw |
| 4 | Stabilizer bar |
Each actuator has a piston which is attached to the inner part of a rotor linear ball screw, which is splined to half of the stabilizer bar. The outer part of the ball screw is crimped and welded into a housing which is attached to the other half of the stabilizer bar. As pressure is applied to one side of the piston or the other, the ball screw converts the linear force applied to the piston into a rotational torque between the two halves of the stabilizer bar.
