Power assembly for electric automobile

Abstract

The invention provides a power assembly for an electric automobile, and belongs to the technical field of machinery. The power assembly solves the technical problems existing in the prior electric automobile that the position of the original engine room is greatly changed, and new parts need to be developed, so that the design and manufacturing costs are greatly increased and the like. The power assembly comprises a driving motor, a water pump and an air-conditioning compressor, wherein the driving motor is powered by a power battery. The power assembly is characterized in that: a transmission device is arranged between the water pump and the air-conditioning compressor and the driving motor. The driving motor drives the water pump and the air-conditioning compressor by the transmission device, so that the whole structure of the assembly is compact, and the model and accessories of the original oil-powered automobile are not changed, so that the driving habits of wide automobile users are adapted, and the re-development of the DC / DC converter, the electric water pump, the electric air-conditioning compressor and the like is avoided so as to greatly shorten the development period and save cost.

Description

technical field [0001] The invention relates to a power assembly of an electric vehicle, which belongs to the field of automobiles. Background technique [0002] In order to alleviate the shortage of oil resources and reduce the pollution of automobile fuel to the environment, the development of new energy vehicles has become the direction of the future development of the automobile industry. In recent years, a pure electric vehicle that replaces oil with electricity has appeared. It replaces the engine with a drive motor powered by a power battery. The function of the drive motor is to drive the wheels; the power battery converts the high voltage of the power battery through a DC / DC converter After being converted into 12V low voltage, it can be used by other electrical appliances (such as lights, radios, etc.) The mechanical air-conditioning compressor is replaced by an electric compressor as the vehicle's cooling power source, and the electric water pump and electric com...

AI Technical Summary

Problems solved by technology

[0003] However, the position of the original engine compartment of the electric vehicle has been greatly changed, and the space in the engine compartment is obviously insufficient. In addition, components such as DC / DC converters, electric water pumps, and electric air conditioners need to be redeveloped, and the design cost and manufacturing cost are greatly increased.
