After the accumulation of the first three sessions of the China Wrecker Operation Skills Contest, it has now become the earliest and only game in China with the theme of clearing obstacles. As a contest car, Dongfeng Capt. N300 is the protagonist of the contest! The car has a higher demand for the chassis and power due to the needs of the car. The superior bearing capacity of the Dongfeng Capt. N300 is through the front and rear axles and suspensions. Frames, wheels and steering are reflected in several key areas.

Before and after the bridge: the same level of vehicle performance and optimal research and development experts told reporters that Dongfeng Kaipute N300 before and after the bridge are using Nissan's technology, and in order to adapt to China's roads and carrying situation, do a more suitable for China's national match design. For the front axle and the same class of vehicles, the I-beam is made of a material with higher tensile strength, and the section size is wider and higher. The bench test refers to the Nissan test standard, and there are more test items and the test load is larger than the national standard. 20 More than %, greater safety factor and stronger carrying capacity. Compared with vehicles of the same level, the rear axle is made of high-strength special-purpose steel for the axle shell, and the section is larger and thicker. Compared with the national standard, the test standards for axle-shell hulls are more demanding and require higher fatigue life. The class vehicle has the best carrying capacity.
Suspension: Reliable strength and sufficient elasticity Considering China's national conditions, the Dongfeng Kaipute N300 leaf spring has been properly strengthened on the basis of design loads to meet the needs of customers' modification and loading. According to experts, the Dongfeng Kaipute N300 rear suspension adopts two leaf springs of the main and auxiliary spring stiffness, and the transverse stabilizer bars are installed so that the suspension has both reliable strength and sufficient strength under no-load or full-load conditions. Flexibility, the car has better stability when turning. The secondary spring adopts the newly developed high-strength spring steel plate, which has a tensile strength of over 1600 MPa. The cross-section of the spring plate in the longitudinal direction is approximately equal stress beam, and has good processability and high reliability. Due to the use of high-strength steel plates and optimized stress distribution design, the quality of leaf springs with equivalent bearing capacity is reduced. Design requirements The fatigue life of the upper leaf spring is 50% higher than that of other models.
Frame: Performance industry leading experts explained that the Dongfeng Kaipute N300 frame adopts special steel with high load-bearing girders. The cross section is 15mm higher than that of an equivalent car. The design fully considers the stress of the frame under various operating conditions. CAE finite element analysis, through the local strengthening and improving the vehicle mass distribution, the stress distribution of the frame, to ensure that the car has a high degree of bearing, its performance is also the industry leader.
Wheels: Optimized Design Performance More Stable Wheels are the only parts of the vehicle. Research and development experts said that the Dongfeng Kaipute N300 wheel steel wheel uses wheel special steel, adding refined grain elements in the ordinary steel, making the steel structure better, more stable performance. The CAE finite element optimization design was applied to the wheel assembly during design to make the force conditions of all parts of the wheel more balanced. The bench test refers to the Nissan standard, the test load is more than 20% higher than the national standard, and the number of bending and radial fatigue tests is higher than the national standard. Increase by 30%. Dongfeng Capt N300 tires adopt radial tires, which have good ground adhesion performance and strong wet-slip resistance.
On the chassis side, Dongfeng Kaipute has a 2.2-ton front axle and a 4.4-ton rear axle, and a 7.00R16 full wire tire, which fully guarantees the car's carrying capacity. In terms of power, Dongfeng Kaipute adopts a true high pressure common rail system to simultaneously assemble large-size gearboxes to ensure greater power output. At the same time, Dongfeng Kaipte, which owns the country's four emissions, is more environmentally friendly and reduces fuel consumption!
