Heavy trucks produced by CNHTC Jinan Commercial Vehicle Company recently installed a new type of suspension system independently developed by CNHTC and with independent intellectual property rights. Therefore, the heavy-duty truck from the gate of Jinan Commercial Vehicle Co., Ltd. will be more straight and straight.
Li Pengxing, Minister of China National Heavy Duty Truck Marketing Department, said: "The car suspension system is like a person's waist and skeleton. As the saying goes, 'waist fitness is strong.' The waist is strong and flexible, and the load a person can withstand will be It was very big. The original Steyr weighed heavy trucks, ran around the road on a bad road all year round, and worked in a complex construction site. The suspension system was under heavy pressure and the service life was shortened.†Li Pengxing said that for this reason, we tailored for heavy trucks. The new suspension system uses high-quality components to reinforce the "waist" of the heavy truck, which significantly extends the service life of the product.
Some heavy truck users often complained to reporters that the actual use of heavy trucks was not as effective as their propaganda. The frame beams were often not bent, and they often collapsed or even broke.
Domestic suspension experts explained this. They believe that the reason for these problems is mainly due to the aging of the design concept of the suspension system and the unreasonable suspension structure, resulting in uneven load distribution and instability, and the stress tends to be concentrated on the bridge axle, resulting in accidents of rollover and axle breakage. . If we want to fundamentally solve this kind of problem, we must start from the design concept and adopt a new international suspension system.
After the efforts of engineers and technicians, the new suspension system was first born in the FAW Technology Center with a strong R&D strength, and was installed in bulk on the newly-launched Aowei Heavy Truck. Last year, a new type of suspension system independently developed by CNHTC was installed as a standard configuration on Haoxi, the main model of China National Heavy Duty Truck Corporation, and other heavy vehicles produced by the company. Recently, the new suspension system has also been implemented for the bulk supply of China National Heavy Duty Truck Group. In this way, the products of the two leading companies in the heavy-duty truck market in China are equipped with new suspension systems, making domestically-owned heavy trucks of their own brands even more powerful.
To the world's advanced suspension technology
According to Yan Qingwei, an expert on suspension of Chongqing Kafu Automobile Brake Steering System Co., Ltd., in the past, trucks were required to change axle sleeves after traveling 20,000 kilometers. In the new suspension system, a key device called the "V-type thrust rod" was used. The device changed the gravity transmission mode of the traditional suspension system, which greatly improved the suspension's bearing capacity, reliability and durability.
"Now European heavy-duty brands have basically adopted such devices. Two or three years ago, this advanced technology was only owned by the famous one or two multinational giants." An engineer at FAW Technology Center said that Liberation Company was the first Aowei Heavy Truck's suspension adopts V-type thrust rod device, which is a major breakthrough in China. Aowei Heavy Truck's new suspension system overcomes the offset problem, increases the load, and is free of lubrication, adjustment-free, and maintenance-free. It has completely reached the international level.
According to relevant experts, China National Heavy Duty Truck Co., Ltd. learns from international advanced technology and independently develops a new type of suspension system that adapts to China's national conditions. The system adopts the latest structure used by internationally renowned brand heavy trucks, namely the V-type thrust rod structure, which distributes the forces evenly to the two side longitudinal beams. The vibration damping module is used between the bridge and the leaf spring to effectively reduce the axle shell and the chassis. The shock will greatly extend the life of the axle housing. At the same time, the new suspension also uses a rear lateral stabilizer. The thick V-shaped thrust bar and the same strong rear stabilizer bar, coupled with back-to-back beams, play a special protective role for the frame load-bearing, and thus effective Improve the lateral stability of the vehicle.
“The actual use proves that the life of each component of the new suspension system under the high load conditions is significantly longer than the original system, and the reliability of the chassis is greatly improved. In addition, the vehicle can withstand extraordinary weight under special conditions, and the balance, stability, and safety The reliability and other performance have also been significantly improved, truly reflecting the mature, safe, reliable, and energy-saving features of the new generation of products,†said industry insiders.
