China's heavy truck and bridge industry is full bloom, how long can Steyr Bridge technology continue?

<


After the Spring Festival in 2011, heavy truck companies face the traditional sales season and have stepped up their production to meet the needs of users. The demand for the heavy-duty truck market is strong, and the demand for key axle axles has also increased accordingly. Some people in the car bridge business said that the current production is very tight and they are working overtime to increase the number of tasks.

â– The ruler is short, inch is good

In 1984, China National Heavy Duty Truck introduced Steyr heavy truck technology. After more than 20 years of digestion and absorption, Steyr heavy truck technology import projects have achieved great success in China. At present, the models produced on the basis of the Steyr heavy truck platform have become the main models of China's heavy truck market. According to incomplete statistics, Steyr platform heavy trucks have more than 40% market share in China.

Steyr dump trucks are very passable, because the Steyr double-speed reduction bridge transmits part of the power to the wheels. Therefore, intuitively, the gear package in the middle of the Steyr double-stage bridge is much smaller than that of the single-stage deceleration bridge, and the ground clearance of the bridge is greater and the passability is enhanced.

Steyr wheel reduction drive axles are products that meet the needs of the European market. The axle load is up to 13 tons and meets European regulations. In addition to the advantages of strong bearing capacity and good passability, such products have many disadvantages, such as relatively low transmission efficiency, high fuel consumption, easy to cause wheel heating due to long-distance transportation, poor heat dissipation, and relatively complicated structure, and high product prices. China's road network is constantly improving, and the construction of expressways is changing with each passing day. The above shortcomings of Steyr wheel-side deceleration drive axles have become increasingly prominent in road transportation.

â–  The changing market

It is undeniable that Steyr Bridge does have better performance, but everything has two sides. Because the shaft head has a deceleration device, the wheels are prone to heat when the vehicle is running at high speed, which will affect the life of the tire, and the transmission efficiency is lower than that of the same type of product. Heavy trucks equipped with Steyr Bridge consume more fuel than trucks with the same configuration of other axles. In the era of high oil prices and promotion of energy-saving and emission-reduction, such drawbacks will affect the competitiveness of the entire vehicle.

After 2000, China’s heavy-duty truck market accelerated its development. With heavy trucks based on the Steyr platform, the market performed very well. The wheel-side reduction bridges were widely used and promoted. The Shaanxi Hande Axle Co., Ltd., known for its production of the Steyr Bridge, grew up during this period.

According to reports, due to the continuous extension of highway mileage, highway heavy-duty tractors have been developing rapidly, and many heavy-duty truck manufacturers have introduced axles that are suitable for high-speed and heavy-duty demand. Among them, there are representative Dongfeng Dana 460 axle, ShanZhiZhi 485 bridge, BeiBin heavy-duty axles with Mercedes-Benz technology, Hande 485 single-stage speed reduction axle, China National Heavy Duty Truck single-stage reduction axle, Ankai 462. Bridge, etc., these axles can meet the requirements of high-power engine matching multi-speed transmission. The Dongfeng Dana 460 Bridge, the Mountain Steam 485 Bridge, and the Beiben Heavy-Duty Bridge not only have good heat dissipation from the wheels, but also have high transmission efficiency, fewer wearing parts, and high reliability.

â–  Various technologies fully bloom

In order to increase market share, domestic major heavy-duty auto companies such as FAW Jiefang, Dongfeng Commercial Vehicle, China National Heavy Duty Truck, Beiqi Foton, Shaanxi Auto, Beiben Heavy Duty Truck, SAIC Iveco Hongyan and other major domestic heavy-duty auto companies compete fiercely. Axle technology competition plays an important role in the competition of vehicle performance.

The domestic heavy truck backbone enterprises have their own supporting axle plants, and the domestic heavy truck leading enterprise FAW is liberated. At the same time, a car bridge company and Shanqi Auto are supplying axles at the same time, and a large number of Nissan truck axle technologies are used. Dongfeng commercial vehicles mainly use Dana axles imported from the United States. Shaanxi Automobile, China National Heavy Duty Truck and SAIC Iveco Hongyan use Steyr axle technology. Anhui Ankai Foton Shuguang Axle Co., Ltd. mainly supplies Beiqi Foton, equipped with Auman Heavy Trucks. With the introduction of Mercedes-Benz's Bei Ben Heavy Duty Truck, the axle can also be self-sufficient.

From this point of view, China's heavy-duty axle technology has shown a full blossoming pattern. Under this circumstance, how to continue the vitality of the products and maintain the long-lasting glory of the Steyr axle is an important issue for Steyr platform heavy truck companies and heavy-duty axle companies.

Corporate voice

Steyr Bridge will not be replaced in the short term

In the first two months of 2011, Hande Axle basically maintained a monthly production and sales volume of 40,000. In Hande Axle products, the axles adopting the Steyr and Mann technology are both available, and the axles that currently use Mann technology account for the majority, accounting for approximately 60%.

At present, the domestic heavy-duty truck market is in a trend of rapid development, but the increase of the Steyr Bridge is far less than that of heavy trucks. In 2010, China’s heavy truck sales exceeded 1 million vehicles, but the proportion of the Steyr Bridge was relatively lower than before.

Now, heavy truck companies such as Shaanxi Auto, China National Heavy Duty Truck, and Beiqi Foton have adopted a large number of double-level bridges with Mantech technology. From the perspective of market share, Mann's bridge is slightly larger than the Steyr Bridge. Steyr bridges are generally used for engineering tipper trucks. The majority of road vehicles use Mannbridge because the fuel consumption is lower than Steyr Bridge and the transmission efficiency is higher than that of Steyr Bridge.

Domestic Steyr platform heavy trucks not only use double-level bridges, but also use single-stage bridges. Steyr Bridge sales are still increasing, but the growth rate has slowed down and market share has also declined. This does not mean that Steyr Bridge will soon be replaced by other axles, because many domestic heavy trucks use Steyr Bridge, and Man's Bridge is not owned by every heavy truck company. After all, Steyr Bridge has a history of more than 20 years of development in China and its market position cannot be ignored.

Steyr axle technology is not out of date

Steyr technology has been introduced into China for more than 20 years. Although it takes a long time, we continue to improve the situation in response to the domestic market demand, so that the Steyr axle has maintained a lasting vitality. If you do not make technical improvements, it may have become obsolete. Although Steyr technology is still used today, it has been very different from the technology introduced in the past.

At present, the proportion of Steyr axles in Chinese heavy-vehicle products is approximately 60%. Steyr double-speed reduction bridges are generally used on sites with poor road conditions. Due to the two-stage drive, the fuel consumption is high.

The axles used by CNHTC mainly include the Steyr Bridge and part of the Mei Chi Bridge. After the local production of axles imported from MAN, it will surely be adopted in large quantities.

Steyr Bridge's market share will decline

Steyr two-stage drive axles are generally used on dump trucks and other engineering vehicles. It is difficult to realize the advantage of high speed running. In addition to the Steyr double-stage bridge, Hongyan also adopts some single-level bridges and also purchases some of the Mei Chi axles. The application rate of single-stage bridges is less than 10%, and it is generally used for road transport vehicles.

In the domestic market, about 60% of heavy trucks use Steyr Bridge. There are many dump trucks for Hongyan heavy trucks. Therefore, Hongyan heavy trucks are mainly equipped with Steyr bridges.

Overall, the use of trucks is more complicated. Different working conditions, different uses, the use of natural different axles. The future trend is that more and more road vehicles will be built, and the proportion of single-level bridges will increase. However, the Steyr double-speed reduction bridge will not disappear, but the proportion will gradually decrease.

Increase in the proportion of single-stage bridges is a trend

One of the liberation heavy trucks, the more used is the Yamaha Bridge. From the source of the axle technology, including Nissan Diesel and Steyr technology. Liberated heavy trucks are mainly based on single-level bridges. In 2010, the sales volume of heavy trucks of FAW-liberation Qingdao Automobile Factory exceeded 100,000 vehicles, of which tractors belonging to roads accounted for the majority of the total and single-stage bridges were used extensively. From the perspective of development trends, the proportion of single-level bridges will increase, and the proportion of wheel-side speed-reduction bridges will decline.

There are several technical sources in China at the wheel hub. In addition to the Steyr Bridge, which has a dominant position, there are also Beiben Heavy Duty Bridges. The technology is similar, and the FAW Liberation Heavy Trucks also use some Northbound heavy vehicles. bridge.
Steyr axle technology is the earliest and most mature technology introduced in our country. Although the passability is good, the wheels are prone to heat when running at high speed, the energy loss is large, and the fuel consumption is high. In recent years, the Steyr Bridge has greatly improved in lubrication and other technical details. The users' awareness is high and they will still occupy an important position in the market.

expert's point

Axle technology lacks independent innovation

Steyr Bridge can take root in our country and grow and grow. It is our company that has seized the opportunity given by history. Steyr Bridge has played an important role in China's heavy truck market and has contributed to it. However, domestic enterprises have not been sufficiently innovative in the introduction, digestion and absorption. On the whole, a new generation of heavy-duty axles that are suitable for China's national conditions and have proven and mature technology and have completely independent intellectual property rights have not yet emerged.

How the axle company digests, absorbs, and reinvents on the basis of the introduction of technology is the topic that the axle industry should focus on during the “12th Five-Year Plan” period. The simple introduction of technology and production in accordance with the drawings can hardly reach the original level of imported technology. In the manufacturing process, we still have a certain gap with foreign developed countries. In the two-axle axle, the most critical parts are the main reducer and the wheel reducer. The life of the main reducer is closely related to the overall design of the axle. If the dynamic design is not good, the gears will not work well. Not only the vibration noise is high, but the product life is also compromised.

Regardless of the axle technology used in the introduction of Steyr, Mann, or Nissan Diesel, if we can avoid weaknesses and develop axles with independent intellectual property rights, companies will not always introduce technology from abroad. The problem is that we have not done so. Regardless of which technology is adopted, during the “12th Five-Year Plan” period, the entire gear industry must step up product innovation and strive to develop a new type of axle with independent intellectual property rights.

Speech

Keep pace with the times to continue to write brilliant

The Steyr axle was introduced into China in the 1980s. After more than 20 years of development, it has become a very representative product in the heavy axle market. Although China's heavy-duty axle technology is presenting a diversified trend, some backbone truck companies have adopted the axle technologies of Japan's Nissan Diesel, German Mann, United States Meritor and Dana, but vehicle companies still adopt a large number of vehicles. Tyre axle. Today, Steyr axles dominate the domestic heavy axle market.

The development of heavy-duty trucks in China is changing with each passing day, and the requirements of the users for the axles are getting higher and higher. In the face of the new market environment, can Steyr axles continue to maintain their status as market leaders? This is a concern for people in the industry. Steyr axles were introduced 20 years ago. They have their own advantages and obvious deficiencies, such as greater weight, lower transmission efficiency, and higher fuel consumption. To continue to be favored by users, we must keep pace with the times and try every means to reduce fuel consumption, reduce self-respect, and adapt to new market changes and new user needs. Only in this way can we continue to maintain our glory.
