Since 2000, the major automobile factory chassis have special focus on the production and sales, private sales of motor vehicle chassis of the total sales of more than 60%. Modified after the rain as the depot is located in the Chunsun. Special Purpose Vehicle involved in many industries, such as construction, sanitation, environmental protection, landscaping, electricity, munications, fire protection, national defense, airports, financial as well as all types of mercial transportation. At present, China has dedicated more than 200 types of motor vehicles, more than 1000 varieties. In short, the Special Purpose Vehicle market prospects, the market access of Power Special Purpose Vehicle with the market39。 the liberation of car only spline interface to connect to the access edge truck browser. Far can not meet the needs of a variety of dedicated devices. Modified to fit the advantages of the depot, that is a dedicated device. A converted small depot in the production of dozens of units, hundreds more cars, not the ability and energy to produce a dedicated device adapted to take power, and can only rely on the chassis parts and ponents manufacturers. Production gearbox manufacturers, due to take the necessary force varieties, specifications, requirements vary, with the total number less, there is no volume, value and small, good production. No attention to the gearbox plant, large quantities only in high universality of the dump truck from a limited ability to make a device changes, or modification to the depot itself, lead to a reduction in functionspecific devices. For example, check our low speed, power shortage, special features, such as defects in action a long time. In order to achieve satisfaction with the special features, modification depot looking for some manufacturers have taken power, and the end result of a small number of varieties, the difference between input and output, and profit do not want to do, or just can not do quality assurance. There is also a factor, the modern automobile products to speed up the rate of replacement, the engine power train, gearbox update soon, two or three years there is the introduction of new products, check our updated browser, not a professional production from a small manufacturer of Power can not keep up the pace of development. It is understood that before there is a check of Power Research Institute, Hubei Automotive Gear Factory is a subsidiary called Yunmeng from the Institute of Power, a very high reputation at the time, only a country, after carrying out the reform disappeared. There are a number of small businesses supporting the depot for the conversion from power devices are in a certain area, supporting the production of a single species, there is no scale of imitation is only slightly modified gearbox factory products to adapt to several models. Because it is imitation, not an accurate transmission of technical parameters, such as taking power away from the center of the gear, check our gear parameters, installation size, resulting in power can not take the normal work of poor quality, short life and even give rise to transmission fight gear tooth, affecting the normal use of the gearbox. All in all, check our product is a dedicated device such vehicle chassis with a dedicated device convergence an important part of an essential, as species, quantity, value and other factors, chassis manufacturer with a dedicated depot do not want more input, so that there a business, requires the development of a professional third party39。s power production from small business petition in the market will be natural selection, do a good job in the legal protection of products to prevent against fake and shoddy products.
