Volvo 760 GLE Rear Axle Suspension

The main objective of the design has been to combine the suspension elements of a live axle in such a way that low frequency (50 - 200 Hz) engine torque fluctuations will be adequately insulated from the body and in this way diminish any tendency to body boom even when driving at low speed with a 4 cylinder car.

The goal should be met without infringing upon other desirable characteristics of the rear axle suspension.

The importance of wind-up compliance, and properly positioned attachment points on the rear axle housing is stressed.

Results from sound and vibration measurement and computation are given.
