Eddy current retarder development

Ten years ago, in China's passenger car industry to bring "retarder" seems to be a relatively new term, but 10 years later, "retarder" the term has become a passenger car industry have repeatedly mentioned on various occasions The popular term, retarder to be able to bring the advantages of passenger cars has been the perception. China's vast, complex terrain, especially in some parts of the landscape hills, which caused the bus to run in the need to brake downhill, resulting from defective brake caused serious casualties on the rise. In the urban transportation system, as a result of China's urbanization process to speed up urban congestion is an increasingly serious problem. Start-up of vehicles, frequent braking, the number of the brake, causing the bus to speed up the aging vehicle braking system, public transportation vehicles and brake transmission of serious cost.

Retarder is entirely targeted solutions to these problems. In the city in vehicles, to extend the retarder braking system 4 to 8 times the life and effectively reduce vehicle maintenance, and operation costs. Passenger in the vehicle, the steep terrain, retarder can effectively alleviate the wheel hub burning heat generated by braking performance led to recession, as well as easy to tire burst early stratification caused by the defects, so that more traffic safety and reduce traffic The accident took place. Electricity, the liquid leading position

Currently in China retarder on the market, retarder, there are two main types. For an eddy current retarder, for a hydraulic retarder. Eddy current retarder of the main suppliers for the Lok Ma France and Thailand, China, and other good-CSF, hydraulic retarder of the main suppliers in accordance with the special blessing for Germany, ZF and so on.

"Eddy current retarder installation, maintenance, maintenance costs are lower, more suitable for the Chinese market, especially the public transport market. Eddy current retarder in particular, low-speed range of 30 km / h when the output torque is better, and city buses During the operation an average of 60% in the speed of 30 km below the "Shanghai Lok Ma Thai retarder of the relevant staff for this reporter. "Hydraulic retarder to adapt to the long slope, very steep terrain big advantage, especially in the heat, the long run will not have a high temperature and therefore will not have a braking effect of decay. Hydraulic and relief The quality of the light-speed, eddy current retarder use of copper, aluminum alloy hydraulic retarder material used to generate the hydraulic torque 2000Nm brake retarder, for example, only one-third of the weight of eddy current non - That for passenger cars to reduce fuel consumption is very good. And there is no additional external facilities, no electromagnetic interference. Although the price higher, the durability, reliability. "Blessing in accordance with special technology-driven system (Shanghai) Co., Ltd. to introduce hydraulic engineer such a retarder.

Two Retarder about the advantages and disadvantages, the bus industry experts believe that a different operating principle is bound to be different, but for passenger cars, different vehicles for the purpose of the request does not retarder, therefore,

choose products To improve the performance of the product is helpful.

In the domestic passenger car market retarder on the merits of a gradual recognition and regulations to improve passenger safety, passenger car retarder of the market have also taken place in the rapid expansion of high-end only in the past from the bus before it can function to the current urban public transport buses to install ; From the last 10 meters above the bus to the installation of the current 8 to 10 meters, 6 to 8 meters or even passenger cars have burst into a strong market demand.

As a result, in a highly competitive market, the retarder manufacturers are constantly adjusting their product's design, marketing, production strategies, such as hydraulic retarder according to the leading-fu will be part of the special types of products The localization of production, has been developed exclusively for the Chinese market, "Maxima" retarder product, greatly reducing the cost of products, enhanced the competitiveness of their products; Lok Ma Thailand has increased the reliability of their products and product weight , With its more market share.
