At present, electric tricycles on the market are divided into three types according to their uses: household, freight and factory. Due to different uses, the technical standards adopted are also different. Most family electric tricycles are side wheel motors with an external frame (the frame is the outside of the wheel). Vehicles with this structure do not have a large axle and have a light load, generally around 200 kilograms. The motor is usually 350-500W, and the battery is 12V20AH, which is suitable for household and walking tools for the elderly. There is also a motor and a large shaft in the middle, (the large shaft is also called the rear axle, the rear beam, which is the axle between the two wheels at the back of the tricycle, tricycle) is an important part of the stability of the car, the motor drives the two wheels at the back The middle, meanwhile, starts to stabilize, but such tricycles are usually more expensive.

　　Freight Type Electric tricycles are also divided into two types, one is the motorcycle type, the configuration and style are similar to a three-wheeled motorcycle, the middle and the big shaft, the electric motor is more than 500 W, and the cargo load is usually 300-600 kg, Equipped with reverse switch, and speed control system. The maximum speed on this road is about 35 kilometers per hour. More than one type of motor tricycle, the motor tricycle after conversion, the rear axle, the trunk completely use the motor tricycle configuration, the load exceeds one ton, can be driven by the transmission speed, 4-5 pieces of 120 Ah high-capacity batteries, more than 900 W DC motor, With or without taxi taxis can also be equipped with hydraulic lifting devices for loading and unloading bulk materials in factories and cities for picking up garbage and so on.

　　Plant-type electric tricycles, the use environment is usually bad, the motor, the battery is durable, can adapt to dust, high temperature, harsh environment, such as frame material, welding process requirements are high, the tube thickness of the frame is 2.5 mm or more, and the diameter of the rear axle is 78 mm, mostly using plasma welding, high-density welding, high tensile strength of the weld, not easy to break. It can adapt to the requirements of the operating environment of electric tricycle manufacturers .

　　Factory-type electric tricycles are generally used in harsh environments, such as electric flat cars, electric water trucks, etc.; electric kiln cars and electric kiln cars for brick factories, kilns, refractory factories, ceramic factories, and firing factories; engineering, tunnels, Electric transport vehicles for sanitation, electric dump trucks, electric sanitation vehicles, etc. Electric transport vehicles and electric dump trucks can also be used for short-distance transportation in flour mills, mineral processing plants, chemical plants, charging stations, farms, wholesale departments, urban and rural households, leasing, etc.
