Title:
WHEEL HUB DRIVE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2016/082628
Kind Code:
A1
Abstract:
A wheel hub drive assembly. A housing (500) arranged within a wheel hub (110) forms a motor cavity that is sealed and provided with an actuating motor (200), a reducer cavity that is sealed and provided with a reducer (400), and a brake cavity that is in communication with the external environment and provided with a brake (300). The reducer cavity and the brake cavity are distributed in the axial direction away from a wheel hub mounting surface. The motor cavity comprises a body (Q1) in proximity to the inner circumferential surface of the wheel hub and a channel (Q2) extending towards the central axis of the wheel hub. An output end of the actuating motor is extended out of the motor cavity after running through the channel and is connected to an input end of the reducer and to an output end of the brake. An output end of the reducer is connected to the wheel hub. A support bearing is provided between a part of the housing (500) in proximity to the radially inner extremity of the channel and a rotor spider and is used for supporting the rotor spider (230). The reducer (400) is capable of increasing simultaneously driving torque and braking torque and reduces dynamic requirements on the actuating motor and the brake. The support bearing is brought into further proximity to the central axis of the wheel hub, thus reducing requirements on the reliability and durability of the support bearing.
