Spur gear differential for motor vehicle, has planetary gearing, planet carrier formed as sum wheel and two difference shafts that are coaxially arranged for sum wheel, which forms output for spur gear differential

摘要

The spur gear differential (1) has a planetary gearing and a planet carrier formed as a sum wheel. The two difference shafts are coaxially arranged for sum wheel, which forms the output for the spur gear differential. The antifriction bearing device (4) is provided for double-sided bearing of the planet carrier. A part of the rolling element (5) of the antifriction bearing device has a curved and arched contact surface in the axial direction of the spur gear differential.
