WITH the increasing power of today's automotive engines, the limited slip differential is coming into more general use. The conventional differential has been found to be inadequate for many driving conditions.
The limited slip differential is one in which the amount of slipping is controlled. This paper discusses three of this type: cam, variable velocity gear, and the friction. The authors describe most fully the latter, concentrating on the Powr-Lok. They include a detailed load and force analysis of the friction-type differential.
The authors believe the limited slip differential greatly increases the utility and safety of a vehicle.
