Title:
A DRIVING BRIDGE DRIVEN BY A MOTOR
Document Type and Number:
WIPO Patent Application WO/2010/012151
Kind Code:
A1
Abstract:
A driving bridge driven by a motor, especially a drive bridge for an electric vehicle, mainly includes a motor (3), a differential (4), a first planetary gear reducer (2) and a second planetary gear reducer (6). The motor (3) is fixed in middle of the driving bridge (1). One end of the motor is coaxially connected with the first planetary gear reducer (2). The other end of the motor (3) is coaxially connected with a differential (4) and the second planetary gear reducer (6) orderly. A brake device (5) is located between the differential (4) and the second planetary gear reducer (6). The design of the driving bridge reduces height of the bridge. The driving bridge utilizes integrated running braking system and parking braking system, so that the axle is safe and reliable to use. The design reduces radial size of the reducers. The axle has less gravity centre and steady operation.
