Differential gear for motor vehicle, has rolling elements arranged in radially inwardly narrow gap and pressed by drivable external gear that is coupled with rolling elements in gap, where gap is formed between races at drive gears

摘要

The gear has rolling elements e.g. tapered rollers and barrel rollers, arranged in a power train between a drivable external gear (1) and drive gears (2) and sectionally formed in conical shape. The rolling elements are arranged in a radially inwardly narrow gap, and are pressed by the external gear that is coupled with the rolling elements in the gap, where the gap is formed between races at the drive gears and has conical shape in cross-section. The external gear is produced from a sliding material e.g. bronze or brass, in a region of ramps.
