User-oriented presentation on "cool" and "tide" of SAIC Hongyan Jieshi C500

SAIC Hongyan boldly launched a young, personalized automotive engineering designer. This time it was an insight at the 17th Shanghai International Auto Show.

The two Jieshi C500 series on display at Hongyan, one is an 8x4 freight train with a central axis, and the other is a 4*2 tractor, which is dominated by Wang Xiaohua and his small partner team at Hongyan Automotive Technology Center. Development completed. This year is Wang Xiaohua's upcoming year. He was graduating at the graduate school of Chongqing University. He was already the youngest worker model of Hongyan. Young he is very sensible, "Our user and driver friends know the car better than our designers in many cases."

"Because they will repeatedly compare horizontally."

"The user's feelings are the first one."

This may be a basic attitude of Hongyan heavy-duty vehicle design for the car: user-oriented, pragmatic, humble.

Wang Xiaohua's summary of the history of Hongyan's 5th generation products was concise and clear. “Under the background of complementing (industry) superiority and lightness (industrial) in that year, in 1965, Premier Enlai established a Chinese heavy-duty automobile plant in Shuangqiao, Chongqing, and introduced. The first-generation French Bellier military vehicle technology was used to manufacture Hongyan military off-road vehicles and developed the Hongyan heavy-duty truck brand.After the transfer of the military, the Austrian Steyr technology was introduced; after a joint venture between SAIC, Italy’s Iveco and Hongyan in 2007, The introduction of Iveco's Stalis, a truck that won the 'Eurostar' award in 2002, from the cab to the engine to the current drive axle, forms the existing Jewel C500 series."

From Jieshi C100 to Jieshi C500, why jump directly from 100 to 500? He told reporters, "This is the fifth generation of products introduced by Red Rock since the introduction of the first-generation Bellietz military vehicle technology after the Steyr, Sunkang, and Jieshi C100 series. Five emission regulations. '5' has a double meaning."

"Middle Axle" As the name implies, the freight trains have two axles placed in the middle, and the traction and telescoping are connected under the frame. This is the biggest difference from the early-stage models. The trailer axles of the trailer type are placed on both sides of the carriage. When turning, the carriages will be directly thrown out. The wear and swing of the tires are greater than that of the center axle.

SAIC Hongyan provides 4x2, 8x4, 6x2 rear lifts, three mid-axle freight train representative models. Wang Xiaohua introduced the SAIC Hongyan this model has three major characteristics: First, large volume, the length of the central axis freight train can achieve 20 meters, the main vehicle can be made of 9.6 meters truck, volume 65 square meters, plus behind the 7.82 meters Hanging shaft, volume 51 square, so the vehicle volume reached 116 square.

This is an express transportation vehicle that is suitable for low-density, high-volume, light-bubble cargoes. This kind of application for replacing heavy-duty tractors is very popular in Europe, the United States, and Australia. Although the trailer can't be exchanged following Chinese regulations, when the main vehicle is used in a bicycle, the 9.6 meters is larger than the 7.82 meters.

The second is simple loading and unloading of goods. The back of the trailer is easily and easily removed. After the trailer is disconnected from the transfer station or service station, it can be transported away with a forklift. The loading and unloading operations of the main vehicle are very convenient.

The third is lightweight. SAIC Hongyan 8*4 Zhongxang freight train wheels, fuel tanks, gearboxes are made of aluminum alloy, the vehicle at least 500 kg weight loss, 9.6 meters truck chassis weight 9.8 tons, plus the trailer after the vehicle less than 13 tons of self-weight . With an air suspension, so the bike can run 32 tons of load. In addition, the air suspension can not only reduce its own weight, but also reduce the height of the chassis and make the volume of the container bigger.

At the SAIC-Hongyan site, another 4×2 tractor from the Jieshi C500 series was fitted with a Corso 13L engine and 560 horsepower. It is currently the largest horsepower model in the domestic market. The overall use of aluminum alloy wheels, fuel tanks, gearboxes, 4*2 high with the vehicle weight control within 6.8 tons. At the same time, the height of its saddle is strictly designed according to 1.1 meters, so that the customs container of 2.6 meters or 2.9 meters can be completely put up and strictly meet the requirements of the regulations of 4 meters. The same use of air suspension is very suitable for box transport.

Wang Xiaohua specifically mentioned that this model has a "Northern Edition" featuring SAIC Hongyan, "using a dual tank design with 800 liters of main tank and 260 liters of auxiliary tank, the main and auxiliary can be switched, and a fuel water heating device is added to the main tank. , This was previously the user to modify their own outside, but Red Rock has set it as a standard.Users can be installed in the auxiliary fuel tank -35 diesel, the main fuel tank installed No. 0 diesel, in the cold weather with a low cost of diesel fuel After the main tank is heated and thawed, it can be used normally. This 'Northern Edition' fuel saving program can save users more use cost."

Hongyan Jieshi C500 series 4*2 tractor “Northern Edition” can also be equipped with an independent heating system for the user to burn diesel, which is more convenient for northern users to “car-home” in cold weather.

In addition, Wang Xiaohua believes that “the cab has a large space. The large 1.8-meter person has no pressure to walk upright in the cab; the configuration is very high, such as the use of disc brakes, retarders, etc. In fact, the car uses Corso 11L, The 450-horsepower engine has already been able to meet the requirements for trunk logistics transportation. Of course, SAIC's Hongyan-matched 510-hp engine will also be available in the second half of the year."

This young man, a 30-year-old handsome who led the design and development of two kinds of show cars at SAIC Hongyan, is still his youngest young man. Together with his hard work and humility, he is able to stand on a user's behalf in order to be able to drive a tractor. The car, he is driving A.

"I don't want to drive a tractor, I don't want to be a veteran driver, or talk about developing a vehicle. My pleasure is that I have to figure this out and understand it and know how to do it. Whether it's car design or studying user needs, I know 'It's a cool thing, I just want to know.'

The young Hongyan automotive engineering designer has a cool tune, and we have reason to expect that in the future, Hongyan’s heavy-duty vehicles will have more humanized, user-friendly, and more fashionable and new designs.
