Title:
COAXIAL TWO-WHEEL DRIVE MECHANISM WITH SINGLE ELECTRIC MOTOR FOR 100% LOW-FLOOR LIGHT RAIL VEHICLE WITH RIGID WHEEL PAIR
Document Type and Number:
WIPO Patent Application WO/2014/206082
Kind Code:
A1
Abstract:
Disclosed is a coaxial two-wheel drive mechanism with a single electric motor for a 100% low-floor light rail vehicle with a rigid wheel pair, wherein two drive units (4) formed of an electric motor (1) and a geared transmission mechanism (2) are longitudinally and diagonally arranged at two sides of a bogie, and the geared transmission mechanism (2) uses a straight-toothed external bevel gear transmission system and drives and connects to a wheel pair by means of an elastic coupling. The two drive units each formed of a single electric motor and a geared transmission mechanism in the driving mechanism are longitudinally and diagonally arranged at two sides of a bogie, yielding a space in the middle of the bogie, reducing the height of the vehicle body floor panel, realising a 100% low-floor fully penetrating-type design, using the characteristic of a rigid wheel pair capable of making the angular speed of two coaxial vehicle wheels the same to drive a wheel pair. The geared transmission mechanism uses a straight-toothed external bevel gear transmission system increasing transmission efficiency.
