1. Uses of three-wheeled electric vehicles
As an important energy source with environmental protection, cleanliness and high conversion rate, electricity is widely used in production and life. Using electricity as the application to drive the upgrading of transportation, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy, and protect the environment is one of the important research topics in various countries around the world. After decades of development, it has been applied In many fields such as electric city bus vehicles, electric transportation vehicles for factories and mines, electric city sanitation vehicles, engineering, tunnels, and special vehicles for subway construction. Electric tricycles have the advantages of strong applicability, mobile recording, simple maintenance, convenient maintenance, and low price, so they can flexibly walk through narrow roads. The electric tricycle has a reverse switch, which can easily realize the reverse driving function. This is very practical in narrow alleys and alleys, and it is very convenient whether to drive or stop. Widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factories, mining areas, environmental sanitation, community cleaning, etc.
2. Classification of Electric tricycles
Electric tricycles are divided into household, freight, and factory models according to their uses. Because of the different uses, the technical standards used are different. Most of the household electric tricycles use side-wheel motors and an external frame (the frame is outside the wheels). This structure has no large axles and has a light load. , Generally about 200KG, the motor is generally 350-500W, the battery is 12V20AH battery, suitable for household and old age walking tools. There are also mid-mounted motors with large shafts. (The large shafts are also called rear axles and rear beams. They are the axles between the rear two wheels of the tricycle and are an important part of the tricycle.) This kind of car has good stability and the mid-mounted motor drives the rear two wheels at the same time. , Starts smoothly, but this kind of tricycle is generally more expensive. For example, Ugbest carbin scooter can driver 60-70 km which have passed Euro4 and EEC. Safe and suitable for most people.
Freight electric tricycles. This kind of vehicle is divided into two types. One is a motorcycle type. The configuration and style are similar to that of a Electric motorcycle. The middle-mounted motor has a large shaft and is equipped with a motor above 500W. The cargo capacity is generally 300-600KG. , Equipped with reverse switch and speed control system. The fastest speed on the road is about 35 kilometers per hour. One is a motorized 3-wheele type, mostly modified from a motorized Electric tricycles. The rear axle and car box are fully equipped with a motorized tricycle. The load is more than one ton. The speed can be adjusted by a gearbox. It is equipped with 4-5 pieces of 120AH large-capacity batteries. , DC motor above 900W, with and without cab, can also be equipped with hydraulic lifting device, used for loading and unloading bulk materials in the factory and the city for garbage removal.
Factory-type electric tricycles are generally used in harsh environments, requiring motors and batteries to be more durable, able to adapt to environments such as dust, high temperature, and rugged roads. They have high requirements for frame materials and welding processes. The thickness of the frame pipes is 2.5MM Above, the diameter of the rear axle is above 78mm, and the welding adopts plasma shielded welding, with high welding density, high tensile strength of the weld, and not easy to break. Can adapt to the requirements of the factory operating environment. Factory electric vehicle tricycles are mostly used in brickyards, such as brickyard drawing cars, electric flatbed cars, electric lifting water-carrying cars, etc.; brickyards, kiln factories, refractory plants, ceramic factories, roasting plants, etc. Kiln cars, electric kiln trucks, etc.; electric transport vehicles for engineering, tunnels, and environmental sanitation, electric dump trucks, electric sanitation trucks, etc. Electric transport vehicles and electric dump trucks are also used in short-distance transportation such as flour mills, mineral processing plants, chemical plants, furnace charge plants, breeding farms, wholesale departments, urban and rural households, and rentals.
