Recently, the Ministry of Transport announced the announcement of the 37th batch of road vehicles with fuel consumption standards (referred to as the "Announcement"), a total of 2742 cards, passenger cars entered the model announcement. Among them, several mid-shaft models entered the list, becoming the first mid-axis models to pass the "Announcement" in the field of the sedan.
In September last year, the first batch of mid-mounted axle models were incorporated into the model announcement of the Ministry of Industry and Information Technology, indicating that the mid-mounted axlecar was the first step in the market as a new model for the sedan. The recently announced fuel vehicle announcement for the standard model, the official launch of the central axis model is just around the corner.
■The first batch of publicized models entered the fuel-supplied central axle model, which is a common model in the foreign sedan market and is relatively new in the domestic market. As early as a few years ago, there were domestic companies that introduced foreign technology and carried out research and development of related models. With the official announcement of the “Road Vehicle Profile Size, Axle Load and Quality Limits (GB1589-2016)†in July last year, the central axle models were classified and their standards were clearly defined. Once the new national standard is released, the R&D and production speeds of the production companies on the mid-mounted axle models will accelerate, and new cars will continue to enter the Ministry of Industry and Information Technology and the fuel announcements, and more waiters will accelerate into this market.
After reviewing the "Announcement", the reporter found that there were three transport vehicles to declare and publicize. Among them, Hengxin Zhiyuan CHX5240TCL vehicle transporter (train) and vehicle transporter (tractor truck) were jointly developed by China National Heavy Duty Truck Group Jinan Truck Co., Ltd. and Changjiu Group's modified vehicle system commercial vehicle business unit in Anhui Zhangzhou production base.
The Hongyan CQ5186TCLHMDG681A and CQ5186TCLHMVG681 carcars on the list are produced by SAIC Iveco Hongyan Commercial Vehicle Co., Ltd. Jiang Jianhua, deputy director of the marketing department of SAIC Iveco Hongyan Commercial Vehicle Co., Ltd., introduced that the Hongyan Jieshi central axle car and the IVECO car were developed on the same technology platform, and adopted the red rock homemade H8A single-stage reduction drive axle, front and rear air. Suspension can effectively reduce the weight of the vehicle.
â– The company actively prepares for the new GB1589 new central axle car classification. In addition, the relevant state departments have clearly defined the governance strategy for the sedan operation industry, which mainly bans the double-row car and promotes the use of the center axle car. Greatly promote the structural adjustment of the car model and the customer operation mode.
There are many hidden dangers in the process of transporting vehicles in the domestic car. In order to load more vehicles, the method of lengthening the fence is often adopted, which leads to overrun. Also. The domestic double-row car has nominally increased the carrying capacity, but in reality it is extremely wide and there are serious safety hazards. The mid-mounted axle car is more suitable for the transportation of vehicles. Under the premise of the same length and not widening, it can be installed more than a few cars in the ordinary car. This effectively solves the problem of the car. For long problems, the center axle car is more reliable than the traditional car.
Under the impetus of GB1589-2016, successively, the mid-shaft models passed the relevant announcements, which effectively promoted the development of the car industry. Commercial vehicle manufacturers are gearing up and ready to go.
“For the central axis model proposed by the new national standard, Shaanxi Automobile has set up a special car transport project team to take the lead in development. Based on the new M30000 product platform of Shaanxi Automobile Delong, the mainstream refit factory of the industry car in the United Nations has newly developed 4× 2, 6 × 2 model series. "Shaanqi car car project leader Wang Fangtai told reporters that their research and development of the production of the axle car has entered the 291 batch of the Ministry of Industry and Information Department announcement, but also confident to enter the 38th batch will be released in April this year Fuel consumption announcement.
Dongfeng Commercial Vehicles related person also told reporters that Dongfeng Tianjin Zhongxing Axis Car is also very mature. The development lasted for 5 years and was derived from Dongfeng Tianjin Platform. It was equipped with two powertrains, Cummins ISDE and Dongfeng DDi75. A total of 8 models can meet the needs of different customers.
â– The development of the mid-axle model can be interviewed. People in the industry have told reporters that with the tightening of regulations, the non-compliant vehicles will be eliminated step by step. The mid-shaft models will be the main models in the future of the car market. More optimistic about the future market.
"According to relevant policies and regulations, a batch of non-standard vehicles will be cancelled in July this year. Therefore, it is expected that the market climax of a wave of mid-mounted axlecars will be ushered in July and August this year." Duan Hengyong, deputy general manager of sales department of China National Heavy Duty Truck Group said China National Heavy Duty Truck Co., Ltd. cooperated with Raul in France to develop a mid-shaft model three years ago and did a lot of preliminary work. Following the introduction of the new version of GB1589, China National Heavy Duty Truck Co., Ltd., in accordance with the requirements of the national standard, will expand the scope of cooperation for the first time and further develop the R&D and production of the mid-mounted axle models. At present, the supply of heavy-duty medium-axle axle chassis is sufficient. If the market needs it, five or six thousand chassis will be provided each month.
Wang Fangtai said that the mid-mounted axlecar is a product that should be produced according to the changes of standard regulations. It has the characteristics of flexible driving, efficient operation, safety and reliability. From the perspective of future trends, the mid-mounted axlecar will replace the tractor as the main model of road transport in terms of long-distance trunk transportation. "In the environment of advocating multimodal transport, the transportation structure will also undergo great changes. The proportion of road transport for long-distance transport will decline. The short-distance transport and distribution for 4S stores will be the main battlefield for road transport. The demand for one-step axle-mounted vehicles will increase."
"With the release of the "Announcement", the mid-mounted axlecar will be officially put on the market soon. After a period of transition, the market demand will gradually increase, and the industry competition will become increasingly fierce." Jiang Jianhua said.
Opportunities are reserved for those who are prepared. In the upcoming emerging market segment, only by closely following the market demand, combined with its own characteristics, with rapid response capability, it can occupy a favorable position and form a competitive advantage.
APPLICATION FEATURES
1. Environment:The bearing is located in the lower part of the chassis, normally working in a dusty and mud splash environment, so it is with high requirement of bearing sealing performance. Working in outside, from low temperature -40 ℃ to high temperature 100℃;
2. Rotating speed: Highest is 3000rpm;
3. Loading: Besides to bear the weight of the main rotating axis, also need to bear the uncertain axial load;
4. Eccentric Oblique angle:Bearing is used with propeller shaft(or drive shaft), need consider to compensate the installation error of the shaft, and the displacement caused by the engine vibration and frame deformation, so the oblique angle of bearing are key factor to be paid attention during bearing design.
