VOLVO TAKES TRACTION ACTION
ROCKLEIGH, N.J. -- Remember that time you were sitting there in snow or mud with one wheel spinning furiously and your car not moving at all? Well, so do the engineers at Volvo, and they decided to do something about it. Enter the automatic locking differential, a compact device which is designed to make foul weather driving a little less worrisome.
The automatic locking differential's function is simple enough. When one of the drive wheels starts to spin due to poor traction, the ALD both slows down that wheel and begins to apply the power to the other wheel where more traction may be available. The system engages smoothly and automatically. It is designed to deliver equal driving force by both rear wheels, effectively "locking" the differential. This is frequently all that is needed to get moving under less than ideal driving conditions.
You might ask, if it is better to drive both wheels equally, why have a differential in the first place? Good question. Think about a car turning a corner, the outside wheel has to go farther than the inside wheel to get around the corner and, since both wheels enter the corner at the same time and finish at the same time, the outside wheel has to turn faster. The differential, through a special gear set, makes this possible. So you need a differential function for curves and corners but not necessarily for starting off from rest.
The ALD suits these requirements perfectly, allowing both wheels to drive equally if one wheel has started to spin under acceleration, then automatically disengaging at speeds over 25 mph in order to have no effect on vehicle dynamics at driving speed. For 1991, Volvo has made the automatic locking differential standard on all 740 Turbo, 940, and Coupes. It may be ordered as an option on 740 sedans and wagons.
Driving in foul weather conditions is not fun, but with the automatic locking differential Volvo drivers should have one less worry on their minds. And that was exactly what the Volvo engineers had on their minds when they set to work.
