Bearing unit for torque transmission device between internal combustion engine and gear box in drive train of motor vehicle, has rotor rotatably arranged on rolling bodies, and pilot bearing integrated in rolling bearing

摘要

The bearing unit (20) has bearing components mounted each other in a twistable manner and fixed between rolling bodies (11a) and arranged in a torque transmission device (1) by a rolling bearing (3) and two bearing rings. The rolling bodies are retained on a base element (9a) by a pilot bearing (9), and a rotor is rotatably arranged on the rolling bodies. The pilot bearing is integrated in the rolling bearing. A bearing sleeve (12) is axially supported on a crank shaft (7) of an internal combustion engine, where the shaft is retained in the torque transmission device.
