What is No-spin differential axle?

Answer 1

The NoSpin differential is a type of differential designed by TracTech, and now owned by Eaton. It permits all the available torque to be delivered to the wheels while still allowing for wheel speed differentiation. Rather than having two side gears and one or more pinion gears (like a standard open differential), it contains a clutch on either side of the spider which mecanically engage with the spider. When one wheel is forced to travel faster than the other (such as the left wheel in a right-hand turn), the clutch on that side of the spider will disengage, allowing that wheel to spin faster. The other wheel will be given 100% of the available torque from the driveline. When both wheels return to spinning the same speed, the clutch engages with the spider again, and the differential basically acts as a locked diff. These differentials are normally used on off road machinery since the engagement and disengagement of the clutches is loud and can be felt through the driveline. They would be very annoying in high traction conditions (pavement).
