Embodiment Construction

[0030] figure 1 A part of a chassis 1 of a vehicle is shown in a perspective view. The chassis 1 has a frame portion 2 and an anti-roll bar (ARB) 3 arranged on the frame portion 2 . The ARB is suitably attached to the frame part 2 at a first location 4 on the left hand side and a second location 5 on the right hand side. The ARB 3 is mounted by bearings relative to the frame part 2 at a first connection location 4 and a second connection location 5, allowing the ARB to rotate relative to the frame part 2 about a center line 6 of the ARB. ARBs are used in vehicle wheel suspension systems. ARB 3 connects the vehicle's left wheel suspension and right wheel suspension. The anti-roll bar 3 includes a first rod portion 7 for connecting a left wheel suspension (not shown) and a second rod portion 8 for connecting a right wheel suspension (not shown). The first rod part 7 has a first connection point 9 which can be connected to the left wheel suspension at the first end of the ARB...

Abstract

An anti-roll bar (3) for a vehicle. The anti-roll bar (3) comprises a first bar portion (7) for connection to a left-side wheel suspension of the vehicle and a second bar portion (8) for connection toa right-side wheel suspension of the vehicle, and an actuator unit (11) connecting the first bar portion (7) and the second bar portion (8) to each other for transferring torque between the first barportion (7) and the second bar portion (8). The actuator unit (11) has a first selectable mode providing a first predetermined torque ratio between the first bar portion (7) and the second bar portion (8), and a second selectable mode providing a second predetermined torque ratio between the first bar portion (7) and the second bar portion (8). The first torque ratio and the second torque ratio are different from each other.

Description

technical field [0001] The invention relates to an anti-roll bar for a vehicle. The anti-roll bar includes a first rod part for connecting the left wheel suspension of the vehicle, a second rod part for connecting the right wheel suspension of the vehicle, and an actuator unit connected to the second A rod portion and a second rod portion to transmit torque between the first rod portion and the second rod portion. Background technique [0002] An anti-roll bar (ARB) for a vehicle connects the left wheel suspension to the right wheel suspension. ARB helps reduce body roll when the vehicle is cornering. Vehicles with rigid ARBs roll less than vehicles with soft ARBs. However, when driving in a straight line and one wheel is going over a bump, a rigid ARB is not the best choice as this wheel will tend to lift the other wheel. This in turn impairs ride comfort. In addition, if independent wheel suspension can be used, the off-road performance of the vehicle will also be imp...
