Abstract

A spur gear differential (1) lockable to a limited extent and used as a differential gear for a motor vehicle. The differential makes use of the friction losses resulting from the oil flow conveyed by the teeth and teeth gaps of the planetary gears (6) and the sun gear (2) or the hollow gear (3). For control purposes, a cover ring (16) is provided which may be moved into a close position, i.e. a sealing position, relative to the end face (17) of the gear teeth or away therefrom to throttle or release the oil flow.
