Title:
DRIVING SYSTEM FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2010/133155
Kind Code:
A1
Abstract:
A driving system for an electric vehicle is provided, including a speed-changing and differential mechanism (30), a first driving motor (10), a second driving motor (11), a motor controller (60) and an electric power resource (20). The first driving motor (10) and the second driving motor (11) are disposed on both sides of the speed-changing and differential mechanism (30) respectively. A power battery can be used as the electric power resource (20), and supplies electricity for the first driving motor (10) and the second driving motor (11). Said motor controller (60) monitors and controls the working state of the first driving motor (10) and the second driving motor (11). The first driving motor (10) and the second driving motor (11) input power to the speed-changing and differential mechanism (30), which inputs power to a first driving axle shaft (40) and a second driving axle shaft (41) so as to force wheels (50)to run. The invention satisfies the power requirement of the electric vehicle, and meanwhile solves the problem of difficult suspension design due to the bad distance between a longitudinal beam and the motor or the speed-changing mechanism by effectively utilizing the layout space of a front compartment. The design of a propeller shaft is relatively simple, thereby enabling the bilaterally symmetric design of the propeller shaft, solving the problem of unbalanced mass distribution of the front compartment, and obtaining a simple and compact structure.
