Gear for use in parking brake actuator of vehicle e.g. passenger car, brake system, has planetary gear unit integrated into wheel of crown wheel gear unit, where wheel and planetary units are arranged at drive and output-sides, respectively

摘要

The gear (14) has a crown wheel gear unit (40), and a planetary gear unit (46) integrated into a crown wheel (30) of the gear unit (40), where the wheel and planetary gear units are arranged at a drive-side and an output-side, respectively. A motor flange is arranged at a housing (28) and provided for attaching a drive motor with a motor shaft (22), where a rotational axis of the wheel is arranged at an angle of 90 degrees to the direction of the shaft. The planetary gear unit has a hollow wheel (50) that is attached to the housing and plunged into a hollow area formed by the crown wheel.
