Innovative and efficient Voith continuous refinement
Time back to the September 2014 Hannover Motor Show in Germany, we can see Voith's products continue to improve and innovation in technology. Andrei told reporters that Voith displayed several new products at the IAA, including the VR115CT, which was released in China in May this year. This is the first domestic hydraulic retarder designed specifically for the Chinese truck market. Voith not only researches and develops products for the European market but also for the global market, the Asia-Pacific and China markets, and hopes to take this opportunity to showcase more new potential customers. In order to adapt to the Euro 6 standard, reduce the total cost of ownership and sustainable business development (low-emission fuel consumption, clean environment, etc.), this year Voith takes the theme of “high-efficiency drive developmentâ€. To cater to this trend, Voith has upgraded its existing products. These include the recently awarded VIAB start-up retarding clutch, the award-winning water medium SWR (rear water media retarder) retarder system and DIWA.6 automatic transmissions for urban buses and coaches, as well as the Voith LP725 and LP490 air compressors, all of which are highly efficient.
According to reports, Voith SWR water medium retarder is the latest generation of retarder, which means that water will replace oil. Currently used in Daimler-Benz trucks and buses and Euro 6 Daimler trucks, the penetration rate in the European market has reached about 80-90%, while the penetration rate in the passenger car market is 100%. SWR uses the engine's coolant for the retarding process, which means that 90% of the vehicle's total braking can be accomplished without wear without the need for additional working media. In addition, it requires only half the installation space compared to the original, and it is lighter in weight, only 35 kg, and it has a maximum power of 520 kW. However, SWR has high requirements for engine coolant, and at the same time requires water stability and applicability of trucks. Andrei said that the current oil medium hydraulic retarder is the most perfect for the Chinese market, and the next generation should be water. Medium, its price is the same as oil medium. When the time comes, with the advancement of the Euro 5 and Euro 6 standards in the Chinese market, Voith will introduce this product to China.
The VIAB-initiated retarder is one of Voith's most outstanding products. It integrates hydraulic coupling and retarding functions in one hydraulic circuit. Currently used in Daimler-Benz trucks, it is suitable for vehicles of over 250 tons. VIAB establishes industry standards to ensure no-wear start and slow speed. Especially in the case of particularly heavy loads and harsh terrain, it provides highly flexible maneuvering and vehicle starting. Compared with traditional torque converter clutches, the system is compact in structure, light in weight and high in efficiency. It will not overheat even under the strongest working load, on uneven roads or when the vehicle is fully loaded on extreme slopes. The development of this cutting-edge technology system has placed efficiency, sustainability and fuel economy at the top of the list since its inception. The system is now available on the construction vehicle of the Mercedes-Benz Arocs. In the future, this product will also be considered for introduction into China and will be localized to be more competitive in terms of price.
At the same time, Voith also developed LP725 and LP490 air compressors for Euro 6 engines. The application of aluminum structures makes the product lighter and the two-stage compression is the latest feature of the Daimler engine improvement development. This includes Mercedes-Benz Actros and Antos and Travego and Citaro. Based on its two-stage compression principle, Voith air compressors can save up to 1L/100km of diesel fuel, while extending the entire life cycle. Since 2012, Zschopau has produced 100,000 air compressors for passenger cars and trucks in cities around the world.
In addition to providing advanced products and technical support, Voith remanufacturing technology is also worthy of industry attention. According to reports, the application of Voith's remanufacturing technology in China is mainly concentrated on the components of automatic transmissions, in order to reduce costs and improve efficiency, while reusing some components to improve its durability. Not only on the hardware, the Voith software program - DIWA SmartNet 2.0 - also offers solutions for transmission diagnosis. With the new generation of SmartNet, data can be transmitted over W-LAN, with significant cost savings compared to mobile communications. It is reported that there are a lot of demand for remanufacturing technology in Europe, Dubai and Hong Kong. At the same time, Voith is also seeking greater development in markets in Southeast Asia, Australia, Malaysia and China. Referring to the remanufacturing of retarder products, Andre said that the technology is still in its infancy, because it requires higher requirements, and more importantly, its cost and savings are not as high as those of automatic transmissions. For this reason, Voith's worldwide service network also offers accessories and replacement assemblies that were rebuilt by Voith. With replacement assemblies, operators can get a retarder that is the same as the new technology. At the exhibition site, Voith demonstrated a special 115HV retarder overhaul, which can be provided as a replacement to the user, reducing the replacement cost of the user's damaged product.
Pay attention to the localization of Voith Turbo hydraulic retarder in China market
"Specialized and precise" is the development strategy of Voith Group. From the perspective of market, we can find that Voith Group's products involve hydropower, steel mines, high-speed rail and other fields, and every product manufactured is very popular. The market share is very high, and it firmly holds the top spot in the world in the fields of hydropower and papermaking.
In the commercial vehicle market, Voith designed a dedicated passenger car transmission and retarder product for the passenger car market. For the Chinese truck market demand, Voith focuses on the retarder field and carefully promotes the hydraulic retarder products. The promotion and application of the Chinese market. Hao Xu told reporters that Voith Retarder has a high market share in Europe, with annual sales of 6-8 million vehicles. In the European market, more than 60% of heavy trucks are equipped with retarder products, and most of these vehicles with retarder products are equipped with Voith retarder products.
Voith, who has extensive experience in market applications, is seeing the continuous improvement of truck safety awareness among domestic users and is targeting China's truck market for the first time. In 2011, he tried to introduce the German import VR 115CN hydraulic retarder product, which will provide hydraulic power. The retarder products have been successfully introduced to the public and gradually guided the change of Chinese users' understanding of the value of retarder products. On this basis, on May 16, 2014, Voith once again penetrated into the Chinese market and tailored a brand new truck hydraulic retarder specifically designed for China based on the operating conditions of Chinese vehicles and the needs of users. VR 115CT products. As a new generation of wear-free braking technology, VR115CT is more in line with the safety needs of domestic users and bring greater economic benefits.
Due to the switch between the country's three-to-four emission standards, the current sales of retarder products lag behind, and all certifications have to be re-made, but Hao Xu expects that in the next two or three years, there will be great development in the domestic market for hydraulic retarders. . With the gradual advancement of Voith's product matching, Voith's truck market sales will also have a substantial increase. Not only that, with the development of China's truck export market, Voith VR115CT has great potential for exporting to overseas markets with vehicle manufacturers.
Hao Xu told reporters that unlike other manufacturers' point power output, the power output of Voith retarder products is uninterrupted, so as to ensure that customers' power needs can be met at any time and users' safety can be guaranteed. At the same time, Voith has a very advanced product advantage in terms of product processing precision and hardware reaction speed. In terms of software programs, Voith also occupies unique technical advantages in matching electronic circuits such as circuits, air circuits, vehicle integration, and ABS/EBS.
At present, Voith's matching work with various manufacturers is in progress. Hao Xu said that matching the retarder with the entire vehicle is a detailed task. From the early stage of technical communication, matching with the vehicle circuit, gas circuit, software program, and even the layout of the vehicle, the process may take one year to complete. Go through serious tests to ensure the stability and reliability of products that will be put on the market in bulk in the future. Currently, Voith has teamed up with domestic OEMs such as SINOCHEM, FAW Jiefang, Hualing, and Dongfeng Commercial Vehicle to conduct matching test operations for specific users in specific regions. For the increasing market demand for modification, Voith is also responsible for the customer responsible attitude, strict inspection of existing vehicles, technical conditions do not meet the requirements do not do, because in Voith's view, the conversion price is high It must be careful not to allow users to spend money.
On the service side, there are few places where the retarder needs to be maintained under normal circumstances, and many truck drivers are aware of the details of the operation and use of the retarder. But Voith is responsible for every customer, from manufacturer training to customer on-site training. Voith insists on doing the right job.
Referring to key development markets, Hao Xu told reporters that Voith's product positioning is mainly in the mid-to-high end market. Due to the special nature of natural gas truck vehicles, even if an engine braking system is installed, the vehicle needs to have a large horsepower, and the braking effect achieved at the same time is only 70% of that of an ordinary diesel vehicle. Therefore, the user prefers the retarder product. In response to this, Voith also focused on LNG/CNG natural gas trucks, hoping to use the development of the natural gas truck market to drive the advancement of retarder products.
“China is the core area of ​​Voith’s global development strategy. Voith’s emphasis on the Chinese market can be seen in developing and designing CT products specifically for the domestic market. In the future, Voith will not only produce in China, but also Design and research and development in China, to create more appropriate product requirements for the Chinese market.†For the future, Andre said that the development of China's truck retarder has only just begun, its development requires the joint efforts of all OEM manufacturers and users to promote This product, which has both safety benefits and economic benefits, has been more widely promoted. As a manufacturer, Voith needs to achieve localization as soon as possible, reduce product costs, and benefit Chinese customers.
