Auxiliary drive electric trailer flat car used for goods and luggage transportation

Abstract

An auxiliary drive electric trailer flat car used for goods and luggage transportation comprises an electric trailer flat car body, at least one electric motor, a drive controller, a signal receiver and a power supply, wherein the electric trailer flat car body mainly comprises a supporting plate, and two front wheels and two rear wheels arranged at the front and back of the bottom surface of the supporting plate; the two front wheels are connected by a front axle; the two rear wheels are connected by a rear axle; the electric motor is installed at the axle; the drive controller is connected with the electric motor and a central controller arranged on a trailer truck; the signal receiver is connected with the drive controller and the central controller; the power supply is electrically connected with each electric component. According to the invention, on the basis of the electric drive characteristics of goods and luggage transportation at the civil aviation airport, under the condition that total power of the whole system is constant, power arrangement is dispersed, the whole is broken into parts, mutual cooperation is realized, and under the principles of optimizing power and lowering the operation difficulty and manufacturing costs, the overall performance of a transport vehicle system is improved and the load distribution of energy medium is improved.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to an auxiliary driven electric trailer flatbed vehicle for transporting goods and luggage. Background technique [0002] With the development of my country's civil aviation transportation industry, the number of flights at large airports has increased rapidly, and the annual passenger throughput has also increased year by year and exceeded 10 million. Luggage trailers, as airport special vehicles, play an important role in the luggage transportation process. In response to the call for energy conservation and environmental protection, the Civil Aviation Administration of China introduced electric vehicles into the field of civil aviation, and implemented the "oil-to-electricity" plan for civil aviation special vehicles, thus realizing the electrification of luggage trailers. [0003] At present, the luggage trailers commonly used in civil aviation are mainly comp...

AI Technical Summary

Problems solved by technology

After the luggage trailer is converted from oil to electricity, the total weight of the battery installed on the trailer head will be very large to meet the above power requirements, and the structural strength requirements will be higher and the volume will be larger if the battery pack is to be carried. , the motor will also need more power, and the domestic high-power motor technology is not mature, which will cause the trailer head to need more materials and larger volume to increase its strength, resulting in a larger high current Loss, battery utilization is not high, motor driving ability is insufficient on ice, snow and slope roads, etc.
