1、 外文资料翻译 Dump Truck Dump Truck mainly refers to the delivery of goods unloaded the car and there is dumping the car, also known as Dump Trucks. Dump Truck is characterized by its compartment can be tilted a certain angle, so that unloading the goods inside. Tilting train is a Dump Truck engine power,
2、 through the dumping of bodies to complete. Dump Truck from the early 20th century there has been continuous development and perfection, has become the main vehicle of transport of goods. Dump Truck unloading a high degree of mobility and mechanization a bit, usually with shovel loaders, excavators,
3、 or belt conveyors and other ancillary use to achieve loading and unloading mechanization, which can greatly shorten the handling time and improve transport efficiency and save labor, reduce labor strength. As the car manufacturing industry, Dump Truck continued introduction of new materials, new te
4、chnology, improve the quality of the utilization factor, with great speed range and high transmission efficiency, control and manipulation of better and more convenient. First, the status of technology development at home and abroad 1. Humanization Further improve vehicle safety, vehicle safety, inc
5、luding performance, braking performance is further enhanced convenience and driver control, comfort is the car at home and abroad reflect the requirements of human development, which is reflected in the body, chassis and other aspects . 1. Suspension System Foreign high-end Dump Truck, such as SCANI
6、A, VOLVO, etc., air suspension with automatic adjustment, and basic domestic or leaf spring, a better use of the rubber suspension. 1. Transmission System Main Foreign is automatic transmission. China mainly with manual gearbox, there are some manufacturers began to try to configure the chassis auto
7、matic transmission. 1. Braking Systems Electric control system mainly foreign (ECBS) and air disc brakes and ABS electronic control system installed. China mainly uses drum brakes, ABS, electronic brake system installed in the smaller, but also began developing the disc brake manufacturers. (4)Body
8、Systems Dump Truck body of domestic comfort than the gap in Europe is still a great car. But high-end cab, driving and ride comfort has been greatly improved than before. 2. Specialization Exclusive of foreign Dump Truck classification is increasingly apparent. In addition to general engineering of
9、Dump Truck, but also according to the needs and purposes century, the development of a dedicated is Dump Truck. (1)Road salt cleaning truck Of snow, snow days will be transported to the road salt, snow on the road sweeping, snow spraying of salt. (2) Class of fluid transport truck pollution Achieve
10、pollution class fluid collection, transportation and dumping, can better protect the vehicle chassis, suitable for road paving and construction of the gravel material transport. China Dump Truck of professional classification is not very clear that the Dump Truck currently mainly used in constructio
11、n, mining, coal transportation, and its degree of specialization than the foreign classification there a larger gap. 3. Structure Optimization European high-strength steel materials often used Dump Truck or a U-shaped carriage frame structure, the advantages are: light weight, great load, more paylo
12、ad can be loaded indirectly increase the loading efficiency； reduce fuel consumption, low center of gravity, good stability , lifting more goods at the time the play, easy to discharge； integral bearing, no or only a few ribs, a small amount of welding； more modern design, the outer surface of a lar

Plastic material has certain of toughness, resistance to low temperature and impact resistance, easy to rattle, and light weight, attractive appearance, lightweigh
14、t is process in playing an important role. There are also a part of the manufacturers of high technical level, through changes in the structure reduces weight and do not reduce the cars performance, the main frame is the use of the car structure. For cost and processing considerations, the domestic

Environmental protection As the worlds growing environmental protection, national environmental protection requirements on the vehicles are more stringent. Dump Truck load of goods sealing requirements increasing. Automotive engine tec

Developed countries in Europe to Euro V vehicle emissions standards, and requirements of the domestic truck is currently the country standard, domestic and foreign well as very large gap, and reduce vehicle emissions of key technologies are only few th

Further enhance the environmental protection requirements, sealing requirements of the Dump Truck also mentioned the agenda, both at home and abroad using a variety of methods to prevent the Dump Trucks cargo sp

Dump Truck in the professional classification abroad also help protect the environment, such as pollution category of fluid transport development and use of Dump Truck, but most major blessing Oh compartment sealed by a Dump Trucks way. Dump Truck of the closures are mainly two: one for soft tarpaulin cover and a metal hard cover. Therefore, foreign vehicles generally do not overload, the basic
