Automobile Leaf Spring

China Shandong Shuipo Electromechanical Equipment Co., Ltd. engaged in the production and sales of trailer accessories for more than ten years, is a collection of design, manufacturing, sales in one of the comprehensive enterprises, the company is located in China's trailer production base. Now the company produces and sells all kinds of trailer accessories, the main products are semi-trailer axle and axle assembly, air suspension system, traction pin, tire support device, steel ring, spare tire elevator, spare tire bracket, air storage cylinder, lock, brake pump, rope tightener, lamps, brake pads, brakes, hinge, door, door knife, rope hook and so on.

Leaf spring: Composed of multiple steel plates of unequal length and curvature. After installation, both ends naturally bend upward. When the impact of the road on the wheel comes, the steel plate is deformed, which plays the role of cushioning and damping. The longitudinal arrangement also has the role of guiding force transmission. The non-independent suspension mostly uses leaf spring as the elastic element, can save the guide device and shock absorber, simple structure.

When the leaf spring is installed in the automobile suspension, the vertical load is positive, all the spring pieces are stressed and deformed, there is a trend of upward bending. At this point, the axle and frame are close to each other. As the axle and frame move away from each other, the positive vertical load and deformation of the leaf spring will gradually decrease, and sometimes even reverse. The winding lug of the main piece is stressed seriously, which is the weak point. In order to improve the stress of the winding lug of the main piece, the end of the second piece is often bent into the winding lug and wrapped around the outside of the winding lug of the main piece, called the wrapping lug. In order to make it possible for each piece to slide relatively during the elastic deformation, a large gap is left between the main piece of the winding lug and the second piece of the wrapping lug. Some suspension leaf springs are not made into coil lugs at both ends, and other support connections are used, such as rubber support pads. The bow plate of our company's trailer truck is 13 thick, 90 wide and 10 plate springs. The fourth plate is bent into a conventional trailer plate spring. The domestic and foreign market is in great demand. At present, it is suitable for medium and large trucks.

60Si₂Mn, 50CrV and other materials are used, and the process is based on blanking, drilling, rolling lug, quenching, tempering, shot peening, fitting, prepressing, painting and other processes.
