Huama Heavy Truck's Foma Axle Co., Ltd. is committed to the study of lightweight axles and continues to innovate. In 2011, the new 460 series single-stage deceleration drive axle was introduced. This dual-link reduction not only reduces the weight of the bridge but also increases the input torque, making it ideal for lightweight heavy truck logistics vehicles, bringing new value to customers.
Lightweight design
It is understood that the current Hualing's lightweight heavy truck Valin Star is very popular with users, one of the hot selling elements is that Valin's Star matches the new BMW 460 drive axle. The bridge shell is made of high-strength steel plate welding, and the high-strength steel plate welding structure is used for the suspension connection with the chassis, which is light in weight and good in strength. The final reducer of the middle bridge and rear axle adopts an integrated main reducer design, which has a compact structure. , Transmission efficiency is high, and the transmission torque is increased by 11% compared to the traditional 457 drive axle, but the weight is reduced by 14%; the brake adopts the crown drum structure, the brake shoe is made of high strength welding plate, and the brake pad structure is eccentric Unequal thickness design not only reduces the weight but also increases the braking force.
In addition, the new 460 Bridge Brake Friction Plate adopts world-class German TMD, Japan TBK and other manufacturers products, non-asbestos, environmental protection and safety, and the life is more than three times the ordinary friction plate. With the installation of a brand-new lightweight 460 bridge, the Valin Star has greatly reduced its weight, and the carrying capacity of the vehicle has not been reduced, ensuring the high stability and high reliability of the on-board process.
Large input torque
Hualing's new 460 drive axle transmission system uses a refined design. The main reducer spiral bevel teeth adopt a contoured tooth design, and the strength increases by 20%. The cylindrical helical gear tooth surface is ground to reduce transmission noise and increase transmission stability. The internal spline adopts the US involute spline design to increase the transmission torque. The entire series of gears adopts high-quality nickel-containing low-carbon alloy steel. The plasticity and toughness after heat treatment increase the strength by 15% compared with common gears. The key parts of the main reduction bearings are imported. Bearings ensure reliability under heavy loads.
Due to a series of high-advanced designs, the new 460 axle input torque is increased. Compared with the same type of axle, the larger the torque output, the larger the bearing capacity, the better the acceleration performance, and the stronger the climbing ability, the number of gear shifts. The less, the wear and tear on the car will also be relatively reduced, thus effectively ensuring that the Valin Star matching the brand new 460 bridge has a higher advantage than other similar heavy truck manufacturers in China.
Wide speed ratio
Hualing new 460 drive axle optional speed ratio of 4.875,4.30,4.10,3.90,3.73, speed ratio across the board, adapted to the country's high-horsepower engine with low speed, high torque platform, obvious advantages of fuel economy. In the complete vehicle matching, especially the lower speed ratio than 4 drive axle 460 drive axle obvious advantages, compared with the ordinary 457, 469, 485 series drive axle, light weight, low fuel consumption advantages highlight.
The Fuma 460 drive axle is not only technically mature, it has passed the severe test of the market, and it is also based on Huaneng's nanny-style door-to-door service to relieve the user's worries and meet the user's fast and timely service requirements for the axle. . With the rapid increase in market demand, the new plant of Foma Axle has also been completed and put into production, providing more reliable and cost-effective products for the entire vehicle company. At the same time, it has also created a huge increase in the overall competitiveness of vehicle products. Economic and social benefits.
At present, the 460 series single-stage deceleration drive axle launched by Foma axle has entered the stage of batch production. It has also been approved by the market through the inspection of the market. It is believed that the technical process of the Foma 460 bridge will surely rise to a new level in the future.
