HOW 'JUMPING CAR' SMOOTHES THE WAY

The demonstration of Bose's new active suspension system on a Lexus LS400 is described. The system allows the vehicle body to glide over bumps, whilst the wheels move up and down. Problems still to be solved include reducing the weight of the suspension unit, making it weatherproof and reducing costs. Bose considered that no conventional hydraulic system had the speed, strength or efficiency to provide the desired goals of ride comfort and body control whilst keeping the wheels on the road. In the Bose system, each wheel is provided with a tubular electromagnetic motor that can quickly move the wheel up and down. The weight of the car is supported by torsion bars. A damper in each wheel prevents excessive bounce. The suspension is fully independent and isolated from the body. A powerful computer manages the electromagnetic springs.
