Spur wheel differential gearbox for fuel consumption of motor vehicle, has sun wheel and planetary carrier arranged to sun wheel, where bearing is configured as roller bearing with rolling bodies located in direct contact with sun wheel

摘要

The spur wheel differential gearbox (1) has a sun wheel (2,3) and a planetary carrier (9) which is arranged to the sun wheel in a coaxial and rotatable manner. A bearing is configured as a roller bearing (18) with rolling bodies which are located in direct contact with the sun wheel or the planetary carrier. The rolling bodies are guided in a cage (25). The roller bearing is designed as an angular contact ball bearing (19). A track (22,23) is formed on the planetary carrier or on the sun wheel, with which the rolling bodies stand in direct, rolling contact.
