Now the freight transport is inseparable from the truck, so there are many drivers who do the freight transport industry, will buy a truck of their own. What are the types of trucks? How to do timely maintenance? These questions are very simple, Top semi trailer manufacturers for you to sort out some content, read will know the answer. Truck is usually called truck, also known as truck, refers to the car mainly used to transport goods, sometimes also refers to the car can tow other vehicles, belong to the category of commercial vehicles. Generally can be divided into heavy and light weight according to the car. Most trucks run on diesel engines, but some light trucks run on gasoline, petroleum gas or natural gas. Truck type semi-trailer The mounting part of a vehicle whose cover engine handling room can be separated from the vehicle body or connected by tools is generally referred to as the board frame, trailer frame or semi-trailer frame. Full trailer That is to say, after mounting a general truck or semi-trailer, a hanging frame, trailer or semi-trailer frame is added. Due to the increase of the radius of rotation, the apparent dead Angle after driving is also increased, so some areas will list it as a special vehicle [example: the world famous Australian road train] Gravel truck Sand truck, also known as mud truck, commonly known as earth truck, is a kind of bucket truck, they are mainly used to transport mud and construction waste, but also used to transport coal, ore, etc. Mixer truck A mixer is a truck used to transport concrete. Flatbed truck Flatbed car a common vehicle for road transport, because it is more convenient to load and unload large and heavy goods, and than other types of the same specifications, can load more goods, favored by transport units. Full hanging slab The load of full-hung flat truck is borne by itself and connected with the locomotive only by hooks. The locomotive does not bear the load of the trailer, but only provides power to help the trailer overcome road friction resistance. Main component Engine: The power source of an automobile, which burns fuel to generate power and then drives the wheels through the drivetrain to move the automobile. Chassis: transmission system, driving system, steering system, braking system to introduce. Transmission system: the power of the engine to the driving wheel, mainly including clutch, transmission, transmission shaft, drive axle. Driving system: the automobile assembly and parts are connected into a whole and play a supporting role for the whole car to ensure the normal running of the car. Mainly includes the frame, front axle, wheels, suspension. Steering system: to ensure that the car can be driven in the process of driving in accordance with the direction chosen by the driver, including steering control mechanism, steering gear, steering transmission device. Braking system: to slow down the car, stop the car and ensure reliable parking. It mainly includes brake control mechanism, brake and transmission device. Body: The place where the driver works and loads goods. Including cab and carriage. Electrical equipment: Electrical systems that assist the driver in operating the vehicle, including batteries, starting systems, lighting equipment, instruments, etc. Maintenance knowledge First protection is critical Most owners of new cars should do enough maintenance in the first warranty period, in accordance with the provisions of the manufacturer, to the special service station to do maintenance, because most car manufacturers have implemented the first warranty free oil change preference for new cars. For example, Shanghai GM will provide free oil and oil filter replacement service for 4 times during the quality guarantee period. But there are also a small number of owners, neither to the staff consultation, also never read the "maintenance manual", so there are also missed examples of the first protection. Because it is a new car, owners miss the first protection, but also the oil turns black, dirty some, will not cause any serious consequences. But experts suggest that owners had better do the first protection, because the new car is in the out-of-close state, the run-in of mechanical parts, the demand for lubricating oil will be relatively high, the significance of the first protection is in this. Two guarantees are also important 40,000-60,000km replacement of brake pads relatively speaking, the two protection is very important. The project involves the testing and maintenance of up to 63 items in eight parts, including engine, automatic transmission, air conditioning system, steering system, braking system, suspension system, body parts, tires, etc. In addition, it also includes the quality test run. It can be seen that the car after so many tests and maintenance, the whole car condition will obviously enter the best state, driving safety can be the best protection. Brake pad Brake pads in general, when the vehicle travels to 40,000-60,000 kilometers will be replaced, for owners with bad driving habits, the replacement trip will be shortened accordingly. If the owner sees the red light in front of him, he does not collect oil but refuel, and then waits for the green light to be released by dragging brake, which belongs to this kind of habit. In addition, if the main car does not do maintenance, it is impossible to find in time the brake skin thinning or completely worn. If the wear of the brake skin is not replaced in time, the vehicle braking force will gradually decline, threatening the safety of the owner, and the brake disc will also be worn out, the owner of the corresponding increase in maintenance costs. Taking Buick as an example, the cost of replacing the brake skin is only 563 yuan, but if the brake disc is damaged, the total cost will reach 1,081 yuan. Tire alignment Note that one of the tire maintenance items covered by the Tire Wear Mark II is tire transposition. When using a spare tire in an emergency, owners should replace it with a standard tire as soon as possible. Because of the particularity of the spare tire, Buick does not use the method of cycle transposition between the spare tire and the tire of other models, but the diagonal transposition of four tires. The purpose is to make the tire wear more average, prolong its service life. In addition, tire maintenance projects also include air pressure adjustment. For tire pressure, the owner can not be underestimated, such as tire pressure is too high, easy to wear the middle of the tread. It is worth reminding that the measurement of tire pressure if not by barometer, the owner is difficult to visually accurate. Daily use of tires is still a matter of details. Such as pay attention to the distance between the tread and the wear mark, generally speaking, the distance within 2-3mm should be replaced with a new tire. Also, if the tire is tied, if it is the side of the tire, the owner must not listen to the advice of the fast repair shop, repair the tire, but should immediately change the tire, otherwise the consequences will be very serious. Because the tire side is very thin, repair will not be able to withstand the heavy pressure, easy to burst the tire. Finally, when we are in daily use, we must maintain and maintain each part in accordance with the prescribed time interval, so as to eliminate the fault in the bud.
