With the rapid development of the transportation industry, trucks are being loaded with more and more load pressures, and braking performance cannot be synchronized at the moment. Especially when driving on mountainous roads, especially on slopes, even seasoned old drivers have to be cautious and prudence, and their personal safety is potentially at risk. To this end, China issued in 2012 the new safety regulations GB7258 requirements truck auxiliary braking system must meet the GB12676 performance testing requirements, the national standard GB12676 test method developed in accordance with the European ECETypeIIA test standards (6 km, 7% slope of 30 km / h), This provision gives a transition period of 2 years and is planned to be officially released in 2014. Braking systems face more tests and challenges.
Recently, Voith Turbo China launched a new truck retarder VR115CT. This is a localized parallel hydraulic retarder designed for Chinese trucks. It fully considers the use environment of heavy trucks in China and has targeted technological improvements. Compared with the VR115CN originally introduced in China, this product not only has high power, high braking force, but also has light weight, low power loss, easy installation, and can achieve downhill cruise constant speed function.
Only Chinese customers customized <br> <br> as the creator of the hydrodynamic retarder, Fu Teyi first invented in 1961 and has developed technical standards, has been more than 800,000 sets of products and services in the world of trucks And passenger cars. After years of practice certification, its economical and safety has been recognized, trusted and recommended by many transportation companies and drivers. As a test water, the company initially introduced the VR115CN hydraulic retarder into China. Currently, it has established cooperation with many key manufacturers such as CNHTC, Shaanxi Auto, Dongfeng, Jiefang, Foton, Fast, and many other complete plant parts.
Taking into account the special conditions of China's road conditions and transportation conditions, Voith’s meticulous research after four years successfully created a hydraulic buffer that is unique to China and will be mass-produced in May this year. Andreas Haseloff, president of Voith Commercial Vehicles Asia Pacific, made it clear that “VR115CT only serves Chinese customers and not other countries. In China, we hope to establish the best customers in China with product design and services that are most suitable for the Chinese market. Long-term partnership, Voith VR115CT's localized production will break the high cost of the imported hydraulic retarder and reshape the economics and safety of the hydraulic retarder, demonstrating the Voith Rio Tinto China truck The resolver market's determination and courage."
Only 38kg of self-weight is convenient for installation. The VR115CT is compact in size, small in size, and weighs only 48kg.
The product is designed in parallel and can be matched to different transmissions. It is suitable for a variety of models. In addition, due to the very simple mounting structure of this retarder, it is necessary to connect part of the vomiting output shaft flange, drive teeth, cooling water pipes and sensors, which is not only easy to assemble, but also easier to maintain. The simple operation interface, good accessibility and modular design make this product very convenient for maintenance, repair and maintenance. The VR115CT can provide up to 3500 Nm braking torque while the vehicle is in motion; its unique rotor disengagement technology minimizes idle power loss; the service brake frequency can be reduced by up to 90%, keeping the service brakes cold The utility model can effectively cope with the emergency brake, get rid of the water spraying device and the additional cost thereof, can greatly reduce the number of shifts, and reduce the wear of the vehicle drive system; especially for mountain users, it can effectively improve the average vehicle speed and improve the operating efficiency. .
Cost 26,000 yuan / year <br> <br> use VR115CT can extend tire life, extend the life of the brakes, thus greatly reducing the operating costs of the vehicle, about a year to recover the cost.
According to calculations, the cost savings that the Voith Turbo retarder can bring to the user during the year include the elimination of the brake water tank (installation and water addition) of 50005,000 yuan, and the extension of the main brake and tire service life of 1212,800 yuan. Reduce downtime to ~ 3,000 yuan, a higher average operating speed ~ 5200 yuan, a total cost savings of ~ 26000 yuan. The actual use process has proved the feasibility of the above data. After a heavy truck uses a retarder, the number of service brakes for the vehicle is reduced by 70%, the brake life is extended by 4-6 times, the shift operation is reduced by 36%, and the average speed is reduced. With an increase of 5.9% and fuel economy of 0.5L/100km, customers can recover their investment costs within one year.
With the development trend of China's trucks with large tonnage, large horsepower, heavy-duty and specialization, and the revision of GB7258 “Technical Conditions for Safe Operation of Motor Vehiclesâ€, the “human concept†of environmental protection, energy saving, high efficiency, and safety has become the consensus of the industry. . Heavy-duty truck mounted hydraulic retarders have become a general trend. In this regard, Voith Hydraulic Retarder has played a role in advancing and guiding, and hopes that its economic performance in the localization process will increase again, enabling more vehicles to be configured. The truck brake safety is more fully guaranteed.
