One Way Freewheel Clutch

WARNING: This page is about a different variant/trim than selected.

The freewheel clutch can perform two functions: Hold the stator stationary and free wheel allowing the stator to rotate without a drive output. The roller type freewheel clutch comprises an inner and outer race and a roller and cage assembly. The inner and outer races are pressed into their related components with which they rotate. The roller and cage assembly is located between the inner and outer races.

The rollers are located in a cage which is a spring which holds the rollers in the 'wedge' direction. It maintains them in contact with the inner and outer races. The outer race has a series of ramps which allow the rollers to lock the inner and outer races together.

When the outer race is rotated in a clockwise direction, the rollers are 'wedged' between the inner and outer races. The rollers then prevent the rotation of the outer race by holding it to the inner race, which is held stationary.
