Abstract
A return stop, including a rotating inner ring and a stationary, fixed outer ring, and a cage arranged between the inner ring and the outer ring with multiple roller pairs each having two rollers. At least one spring element is arranged between the two rollers of each roller pair for spring-loading the rollers at least against the outer ring, and on an outer circumferential surface of the inner ring for each roller of each roller pair, a clamping ramp is formed. The outer circumferential surface of the inner ring has at least one cam that is formed radially on the outside and engages in a groove formed on the cage. The at least one cam is smaller in the circumferential direction than the groove. Through a relative movement of the cage relative to the inner ring, the respective roller of each roller pair contacts both the respective clamping ramp and the outer ring. A transfer case for a motor vehicle with such return stop is also provided.
