Problems solved by technology

[0004] The gearbox is an important part of an electric vehicle, but the electric drive principle currently used in China is a three-phase AC motor, which is bulky and heavy, which increases the power consumption of the vehicle, cannot effectively adapt to a pure electric bus, and has low mechanical efficiency. Poor shifting performance, which limits the further development and promotion of electric vehicles, especially electric buses

Abstract

The invention discloses a three-gear double-clutch type automatic gearbox for a pure electric bus. The three-gear double-clutch type automatic gearbox comprises a double clutch and a three-gear transmission mechanism, wherein the odd clutch in the double clutch is connected with transmission chains of the first gear and the second gear of the gear mechanism, and while the even clutch is connected with the transmission chain of the second gear in the gear mechanism. The three-gear double-clutch type gearbox is large in transmission torque, reasonable in speed ratio configuration, accurate to shift under the electric control hydraulic and the control of a TCU, small in shifting time, high in transmission efficiency, and effectively suitable for the pure electric bus.

Description

technical field [0001] The invention relates to a power transmission system, in particular to a pure electric power transmission system. Background technique [0002] Automobiles are an indispensable means of transportation for human beings. However, with the aggravation of environmental pollution and the continuous reduction of non-renewable resources, people are more and more interested in the development and research of electric vehicles. [0003] An electric vehicle (EV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Because it has less impact on the environment than traditional cars, it has received strong support from the government and the public. [0004] The gearbox is an important part of an electric vehicle, but the electric drive principle currently used in China is a three-phase AC motor, which is bulky and heavy, which increases the power ...
