Classification of Electric Tricycles
Electric tricycles can be divided into household type, freight type and factory type. Because of different uses, the technical standards adopted are also different.
Household electric tricycle
Most of them are side wheel motors with an external frame (the frame is outside the wheel). The car with this structure has no big axle and has a light load of about 200kg. The motor is generally 350-500w, and the battery is a 12v20ah battery, which is suitable for household and elderly walking tools. There are also middle mounted motors with big axles (the big axle is also called rear axle and rear beam, which is the axle connecting the rear two wheels of the tricycle, and an important part of the tricycle). This kind of car has good stability. The middle mounted motor drives the rear two wheels at the same time, and the start is stable. However, this kind of tricycle is generally expensive.
Freight electric tricycle
This kind of vehicle is also divided into two types. One type is motorcycle type, with the configuration and style similar to that of a three wheeled motorcycle. The middle motor is equipped with a large shaft, and is equipped with a motor above 500W. The load capacity is generally 300-600kg, equipped with a reverse switch and a speed regulation system. The fastest speed on the road is about 35 kilometers per hour. One is a motorized tricycle type, which is mostly modified from motorized tricycles. The rear axle and trunk are completely configured with motorized tricycles, with a load of more than one ton. It can be adjusted by the gearbox. It is equipped with 4-5 120ah high-capacity batteries, DC motors of more than 900W, with or without a cab. It can also be equipped with hydraulic lifting devices, which can be used for loading and unloading bulk materials in the plant and for clearing and transporting garbage in the city.
Factory type electric tricycle
The operating environment is generally poor. The motor and battery are required to be durable and can adapt to dust, high temperature, rough roads and other environments. The requirements for frame materials and welding process are high. The thickness of the pipe used for the frame is more than 2.5mm, and the diameter of the rear axle is more than 78mm. The welding adopts plasmon shielded welding. The welding density is high, the tensile strength of the weld is large, and it is not easy to fracture. Be able to adapt to the requirements of factory operating environment. Factory electric tricycles are widely used in brick factories, such as brick factory blank pulling cars, electric flat cars, electric lifting and transporting water billets, etc; Electric kiln charging vehicle and electric kiln discharging vehicle for brick factory, kiln factory, refractory factory, ceramic factory, roasting factory, etc; Electric transport vehicles, electric dump trucks, electric sanitation cleaning vehicles, etc. for projects, tunnels and sanitation. Electric transport vehicles and electric dump trucks are also used in flour mills, concentrators, chemical plants, charging plants, farms, wholesale departments, urban and rural households, rental and other short-distance transportation.
Make a purchase of Electric Tricycles from China, you can get them at a good price if you have a large quantity. We hope to be your long-term partner.
