Problems solved by technology

[0003] However, pure electric vehicles still have many unsatisfactory shortcomings. The driving mechanism used in existing electric vehicles is still the model of electric motor + gearbox + differential. Due to the complex structure, difficult assembly, heavy weight and manufacturing cost of the gearbox Insufficient high level will greatly increase the production cost of the whole vehicle
Traditional electric vehicles also have shortcomings such as short mileage and poor power performance due to battery power and motor power, which has become the main bottleneck for the widespread promotion of pure electric vehicles

Abstract

The invention provides a power train of a new energy electric vehicle and belongs to the field of new energy vehicle application. The power train comprises a controller, a motor and a decelerator connected with the output end of the motor, wherein the controller comprises a main control panel, as well as a DC/DC converter and a high pressure controller which are connected with the main control panel; the output end of the main control panel is connected with the input end of the motor; and the DC/DC converter is connected with the high pressure controller. The power train has the following beneficial effects: the space is fully utilized reasonably, mass distribution is balanced, part layout and directions of high-voltage and low-voltage wiring harnesses are optimized, the power train and the whole vehicle can be favorably maintained, and the assembly and maintenance workloads are reduced; and parts can be quickly produced and replaced, and the mounting accuracy and speed of the whole vehicle are improved.

Description

technical field [0001] The invention relates to the application field of new energy vehicles, in particular to a new energy electric vehicle power assembly. Background technique [0002] With the increasing energy shortage and environmental pollution and the rising international oil prices, pure electric vehicles, as a branch of green new energy technology, have zero emissions, low noise, relatively simple structure, and can realize the diversification of transportation energy sources, etc. Advantages have become the development direction of future automotive technology, and are favored by people, and the market share is also increasing year by year. Compared with traditional cars, new energy electric vehicles reduce emissions, because of their clean and energy-saving characteristics, they are currently very significant for the development of low-emission vehicles and one of the important directions for the future development of the automotive industry. [0003] However, pu...
