See 11 various kinds of vehicle differentials as well as find out exactly how they function. This video is intended for pupils in the AUSV 1220 Manual Drivetrain course at Weber State University with Teacher John D. Kelly.
CORRECTIONS:
1. The differential I called a “Detroit Locker” is not a Detroit Locker. It is just an Eaton Posi Limited Slip differential. A Detroit Locker utilizes canine teeth and also is a truly securing differential. Thank you goes out to Keith MacDonald for capturing my mistake.
I did not effectively describe just how the clutch packs of a limited-slip differential are applied. The easy rotation of the side gears versus the differential pinion equipments does not trigger clutch packs to apply, or else, the clutches would apply when turning corners at low load (low torque). The more torque you provide to the differential side gears the higher the pressure on the tilted (ramped) teeth, the higher the force on the clutch packs.
3. There is greater than one design of Torsen differential. See the JTEKT Corporation’s web site to learn more https://www.jtekt.co.jp/e/products/lsd.html
I improperly explained the operation of the original 1956 Dana limited-slip differential. The pinion pins on the initial Dana differential have actually tapered ends. Under a load, the differential case applies rotational torque to the pinion pins creating them to slide up the V-shaped ramps.
