The "Dual Mode Suspension" equipped with the 16-v turbo model has front active anti-roll bar that has a hydraulic actuator built in the anti-roll bar link. SYSTEM BENEFITS Unlike passive stabilisers, in active sys-tems, the two stabiliser halves are con-nected by a mechatronic actuator which provides the torsion between the halves. Don Sherman. Although rollovers are relatively rare events, they are usually deadly accidents when they occur. High-end Audi crossover models (SQ7, SQ8) also feature electromechanical Active Roll Stabilization (eAWS): On each axle, between the two havles of the stabilizers is a compact electric motor with a three-stage planetary gear set. The relatively low roll stability of heavy vehicles is the … These systems are usually designed for vehicles to change the roll stiffness of the vehicle, thus preventing a potential roll-over. In order to improve roll stability, most of modern heavy vehicles are equipped with passive anti-roll bars to reduce roll motion during cornering or riding on uneven roads. 1. active anti-roll bar control drastically reduces the normalized load transfer, compared to the passive anti-roll bar. When cornering, the lateral inclination (roll) of the SUV’s body is significantly reduced by the active anti-roll bars. FOR RANGE ROVER MK III L322 FRONT SWAY BAR ANTI ROLL BAR … 60 mm either on one side or as an aggregate on both sides. INTRODUCTION 1.1 Background The rollover of heavy vehicle is an important road safety prob-lem world-wide. The active anti-roll bar system has been proven to be one of the most effective solutions to improve roll stability of heavy vehicles. or Best Offer. Anti-roll bars primarily influence suspension behaviour when driving over bumps in the road surface affecting only one side of the vehicle, as they transfer the forces to the other side. More papers are written about Active Anti-roll bars (AARB) in automotive and mechanical field. The first production car to use an active anti-roll bar was the 1988 Mitsubishi Mirage Cyborg. Semi active anti-roll bars. Add to basket. 458 Posts . First production car was Mitsubishi Mirage Cyborg in 1988. Offering better handling through hydraulics. So you will never have to compromise on your fun-to-drive elements. Active Stabilizer Bar Systems DESCRIPTION BWI Group’s Stabilizer Bar Systems are a family of products that enhance vehicle performance both on-road and off.
