There are so many types of asphalt road maintenance vehicles . How do we classify them? The answer to this question is as follows: Asphalt pavement multipurpose maintenance vehicles can be categorized according to the methods of quality, driving mode, transmission mode and power plant.
1, according to load quality
Due to the current domestic production of conservation vehicles, general use truck chassis is generally used as a base vehicle, so the vehicle can be divided into small, medium, and large types according to the size of the truck load. Less than 3 tons of small conservation vehicles, 3 tons to 5 tons of medium-sized maintenance vehicles, larger than 5 tons of large conservation vehicles
2, driving method
According to the driving mode, the car can be divided into two kinds: drag type and self style.
Trailer maintenance vehicle: This type of maintenance vehicle is equipped with a variety of equipment and devices mounted on a trailer chassis. It uses its own engine output power to drive various devices and implements. It is pulled by a truck or tractor to carry out maintenance operations on the road.
Self-propelled vehicle: This kind of vehicle is equipped with a variety of equipment and devices on the chassis of a truck or on a dedicated self-propelled chassis. There are two types of equipment: the power taken out of the chassis and the engine. Most domestic and foreign production vehicles are self-propelled.
3, according to the transmission method
According to the transmission mode, the maintenance vehicles can be classified into five types: mechanical transmission type, hydraulic transmission type, electric transmission type, pneumatic transmission type, and integrated transmission type.
4, press the engine
According to the type of engine maintenance vehicles can be divided into gasoline engine maintenance vehicles and diesel engine maintenance vehicles.
Trailer maintenance vehicles have the characteristics of simple structure and do not occupy traction power when they are not performing maintenance work, but have poor maneuverability and operating conditions. Self-propelled vehicles have the advantages of being flexible and easy to operate. The way in which mechanical drives directly drive working devices has gradually been eliminated. Pneumatic transmissions are not widely used due to their low efficiency, high vibration, difficulty in control and operation, and are used only for spraying asphalt and sweeping road surfaces. Hydraulic and electric power transmission oxides are simple, convenient, easy to control and operate, and are commonly used in maintenance vehicles . The drive mode and the layout are simple and easy to use because the engine drives the generator and the motor drives the maintenance work tools.
