Abstract

The invention provides an electric power transfer device with high-speed dual-power source input. The electric power transfer device comprises a gearbox and a power input device, wherein the gearbox comprises a gearbox auxiliary box and a gearbox main box; speed reducing gears are symmetrically arranged in the gearbox auxiliary box; the gearbox main box adopts a two-gear shifting structure with two middle shafts; and the two middle shafts, gear transmission mechanisms which are symmetrically arranged, and a connection sleeve mounted on an output shaft are arranged in the gearbox main box. According to the technical scheme of the electric power transfer device disclosed by the invention, the power transfer is guaranteed, and the noise and the phenomenon of reducing vibration led by the high-speed transmission can be effectively reduced; through the technical structural design, torque borne by the gearbox is reduced, the service life of motors and the service life of a transmission system are prolonged, and the efficiency of the transmission system is improved.

Description

technical field [0001] The invention relates to the power and transmission system of an electric passenger car, in particular to an electric power transmission device with high-speed dual power source input. Background technique [0002] At present, automobile emission has become one of the main factors of environmental pollution. In order to protect the environment and reduce automobile emission, the development of pure electric buses has become one of the important means to solve environmental protection problems. Due to the high driving power and torque requirements of pure electric buses, there are two forms of single-motor drive and dual-motor drive. Compared with single-motor drive, the power and torque requirements of each motor are lower in dual-motor drive, which is easier to do. When running at high speed and light load, the efficiency of the system will be higher and the cost will be lower; however, there are many disadvantages in the existing dual-motor coupling ...
