limited-slip differential

English

Noun

limited-slip differential (plural limited-slip differentials)

1. (mechanics) A type of differential that allows its output shafts to rotate at different speeds but can limit the maximum difference in angular velocity between the output shafts, allowing greater torque to be applied to the slower-spinning shaft(s) and generally resulting in better traction than older-design differentials. [from 20th c.]

   Synonyms: LSD (abbreviation), limited-slip diff (shortened form)

     To get the facts on just what a limited-slip differential contributes to mobility under slippery conditions as well as on dry roads, we drew up plans for a series of tests

   • 1979 September, Paul Weissler, “Servicing the four-wheel drive Eagle”, in Popular Mechanics, page 94:

     A limited-slip differential on the transfer case divides the torque between front and rear axles, even if one axle has lost traction. This is similar to the limited-slip differential, optional on rear-drive cars, that transmits power to both rear wheels, even if one has lost traction

   • 1992 November, Don Chaikin, “HOW IT WORKS: LIMITED-SLIP DIFFERENTIAL”, in Popular Mechanics, volume 169, number 11, page 104:

     This wrinkle in the system is corrected by a limited-slip differential. While some carmakers use a viscous coupling in the rear differential, carmakers typically use a simple clutch-and-spring system in limited-slip differentials

   • 2019, Kirk VanGelder, Fundamentals of Automotive Maintenance and Light Repair, page 558:

     Limited-slip differentials allow normal differential action under normal driving conditions. But when road conditions are slippery, the limited-slip differential reduces or prevents differential action. This makes it so that a wheel cannot spin freely. Drive is maintained to both wheels. There are two main types of limited-slip differentials—- clutch-style and gear style.
