Roller free-wheel e.g. case or pinch roller free-wheels, for use in e.g. automatic transmission in motor vehicle sector, has springs for springing clamping rollers, where springs are arranged at cage bars extended between cage rings

摘要

The free-wheel (1) has a cylindrical outer ring with clamping ramps formed at an interior surface of the outer ring. Clamping rollers (4) are spring-loaded against the clamping ramps. A cage (3) is arranged in the outer ring in a torque-proof manner, and the clamping rollers are taken up at the cage. Springs for springing the clamping rollers are arranged at cage bars (10) that are extended between two cage rings (8, 9), where the cage rings have an outer edge form. The outer edge form is section-wise adapted to shape of the interior surface within the region of the clamping ramps.
