How to extend the life of the vehicle by using light, low-profile, semi-trailer maintenance knowledge

How to extend the life of the vehicle? This is a big problem for many riders, mainly from maintaining a good technical state of the car, which is more conducive to extending the life of the vehicle. In fact, its content is more extensive, including knowledge of car beauty care, and summed up, mainly in the following three aspects:

Low-profile semitrailers are commonly used for the transportation of heavy-duty vehicles (eg tractors, buses, special-purpose vehicles, etc.), rail vehicles, mining machinery, forestry machinery, construction machinery (eg excavators, bulldozers, loaders, pavers, cranes, etc.) ) As with other heavy cargoes, the lower the center of gravity, the better the stability and safety, and the greater the ability to transport ultra-high cargo and obstacles through the head. Low-profile semi-trailers usually use concave-beam (or well-type) frames, and the front frame of the frame is a gooseneck. The traction pins on the front part of the gooseneck are connected with the traction saddle on the tractor, and the rear end of the gooseneck and the semi-trailer frame. Connected), the middle section is the cargo platform (the lower part of the frame) and the rear end is the wheel frame (including the wheels).

When loading mechanical equipment onto a low-bed semi-trailer, it is common to load mechanical equipment from the rear of the semi-trailer, ie to move the mechanical equipment from behind the rear wheel frame or remove the wheel, and then fix the mechanical equipment on the semi-trailer. on.

Low-velocity semi-trailers carry a wide range of cargoes and are suitable for the transportation of various steel materials for a variety of mechanical equipment, large-scale articles, highway construction equipment, large-sized tanks, and power plant equipment.

1. The series of low-profile flat semi-trailers have plate-type, concave-girder-type and tire-exposed structures. The longitudinal beams are flat or gooseneck type. The frame is a ladder type, and the cross-section of the girder is I-shaped, which is characterized by high rigidity and high strength. 2. The main plane of the cargo rack cargo platform is low, which ensures the stability of transportation and is suitable for carrying all kinds of construction machinery, large-scale equipment and steel materials.

3, the use of three-axis balance, dual-axis balance or rigid suspension, with a mass balance block between the front and rear leaf springs, can make the front and rear leaf spring deflection changes, so that the front and rear axle forces balanced;

4. The low-profile semi-trailer series products are applicable to a variety of mechanical equipment, large-scale articles, highway construction equipment, large-size tanks, and power station equipment and various kinds of steel transportation. They are widely used, efficient and quick. The vehicle adopts advanced computer-aided design software to optimize the design. The design of the load-bearing surface of the frame is designed according to the user's requirements to satisfy the transportation of various special cargoes.

The main types of low-profile semi-trailer are: two-axis high and low flat semi-trailer, two-axis four-axis high and low flat semi-trailer, three-axis high and low flat semi-trailer, three-line six-axis high and low flat semi-trailer. The low plate load depends on the number of axes, the size of the tire, and the load of the low-profile semi-trailer. The greater the number of shafts, the greater the load, and the load range of 20 to 150 tons. According to the number of axles, the size of the tire and the load of the low-profile semi-trailer are also different. The greater the number of axles, the greater the load and the load range of 20-150 tons.

First, the body care and maintenance of the body is also used to call the semi-trailer beauty, the main purpose is to remove the body and body of the car outside the various oxidation and corrosion, and then to be protected to highlight the car's "beauty." It mainly includes: car paint maintenance, cushion carpet maintenance, bumper, skirt maintenance, dashboard maintenance, electroplating processing and maintenance, leather plastic maintenance, tires, wheel warranty, windshield maintenance, chassis maintenance, engine maintenance and other appearance. Second, the car maintenance

The purpose of car body maintenance is to keep the car young. The purpose of car maintenance is to make the car run hundreds of thousands of kilometers without major repairs, to ensure that the car is in a good state of technology. It mainly includes: lubrication system, fuel system, cooling system, brake system, and carburetor (injector) maintenance.

Third, the body refurbishment, such as deep scratches diagnosis, treatment, multi-material bumper repair, wheel (cover) hard repair, leather, chemical fiber material renovation, engine color renovation and so on. How to extend the life of the vehicle by using light, low-profile, semi-trailer maintenance knowledge

Semi-trailer maintenance is divided into two types: regular maintenance and non-regular maintenance. Regular maintenance includes daily maintenance, primary maintenance and secondary maintenance. Non-regular maintenance includes maintenance during break-in period and seasonal maintenance. The main work of car maintenance is nothing more than cleaning, inspection, tightening, adjustment and lubrication. However, with the development of science and technology and the automotive industry, various advanced technologies based on computers are widely used in automobiles, making the future cars gradually becoming more intelligent, and thus the contents of semi-trailer maintenance have been given new connotations.

The maintenance of semi-trailer is a relatively technical and complex task. It is difficult for the driver alone to finish the maintenance of the semi-trailer and it is necessary to go to the auto maintenance company. Now, in China, there are still some car maintenance companies clinging to the traditional concept of maintenance, maintenance equipment and tools obsolete, maintenance methods and methods are still old, with the current need to meet the needs of modern development. In addition, the service quality of individual maintenance companies is worrying. In order to seek profits for "black box operations," old and new ones are used for maintenance, and good repairs and maintenance fees and replacement fees are in full charge. Therefore, to remind drivers to maintain the car must choose strong technical force, reliable service quality, good reputation of the maintenance company, not to bother, save money and not to maintain the semi-trailer, so as not to lose the big.
