Product Introduction

Leaf Spring (Leaf Spring) Leaf Spring is the most widely used elastic element in automobile suspension. It is composed of a number of alloy spring sheets of equal width but unequal length (the thickness can be equal or unequal). An elastic beam of approximately equal strength. Automobile leaf spring is the most traditional elastic element in automobile suspension system. Because of its good reliability, simple structure, short manufacturing process, low cost and greatly simplified structure, it has been widely used. Automobile leaf springs are generally composed of several pieces of alloy spring steel with unequal lengths to form a group of spring beams with similar strength.

Automobile leaf spring is the most traditional elastic element in automobile suspension system.

Automobile leaf springs are generally composed of several pieces of alloy spring steel with unequal lengths to form a group of spring beams with similar strength.

Product Features And Applications

In addition to the buffering effect in the suspension system, when it is placed in the longitudinal direction of the car and one end is connected to the frame with a fixed hinge, it can be responsible for transmitting all forces and moments in all directions and determining the trajectory of the wheel movement. Play a guiding role, so there is no need to set up other guiding mechanisms. In addition, the car leaf spring is composed of multiple sheets. When deformed under load, each sheet has relative sliding and friction, which generates a certain resistance, which promotes the body The vibration attenuation, so the use of this structure can not be equipped with a shock absorber. However, the energy stored per unit weight of the leaf spring is the lowest, and the utilization rate of these materials is the worst. Generally, multi-leaf spring ε=60%, and less-leaf spring ε=75%~85%. It consumes a lot of alloy steel, and its weight accounts for 8-9% of the car's own weight.

Production equipment and technological process

Processing route of automobile leaf spring:

Cutting → straightening → drilling → rolling ears → quenching + medium temperature tempering → shot peening → assembly → pre-compression

After-sales service

The company pays special attention to after-sales work. The strong after-sales team sticks to 24 hours in the province and 48 hours outside the province to arrive at any place that customers need on time. All products are returned unconditionally due to quality problems, and customer satisfaction is our pursuit.
