Description

technical field [0001] The invention relates to a power transmission system, in particular to a power transmission system of a pure electric bus. 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 drive system provides the power required for the operation of the entire bus and is the core component of the electric vehicle. However, the existing electric bus drive system is ...
