Lorry leaf spring

Specification: 38*100*1560
Material: SUP9 (55CrMnA)
This model of leaf spring assembly 94832001505 is composed of five steel plates, one central bolt, one nut and four central sheets. In the leaf spring assembly, the straight length of the first steel plate is 1560 mm, and the straight lengths of the second to the fifth steel plate are all 1480 mm, so that the leaf spring assembly is a heavy parabolic product. This leaf spring is made of durable materials and by advanced techniques, and is produced via long-taper calendering, head and edge trimming, punching and other procedures. Additionally, the production difficulty of this leaf spring lies in the pressing of lateral lugs and drilling of holes at both ends of the first steel plate. This procedure highly tests workers’ technical skills and production expertise, as it must not only meet the demands in drawings, but also fulfill requirements for sturdiness and durability.

An automobile leaf spring mainly acts as an elastic element for an automobile suspension system. Further, the friction between a plurality of spring leaves plays a role in damping in the system. In most automobile leaf springs, lugs and brackets are also used for guiding.

We also utilize domestically advanced specialized equipment such as multi-function presses, hydraulic quenching machines, hot-air circulation tempering furnaces, and stress shot blasting machines to maximize the metal performance of the leaf spring, thereby extending their service lives.
Our company is also intensifying efforts in new product development, continuously updating production processes for products to meet clients’ demands, and accepting orders based on OEM numbers provided by clients.
