Parabolic Leaf Spring

Parabolic Leaf Spring

Automotive leaf springs are also called blade springs.

Since leaf spring products are not final products, they are parts belonging to other products, and they are very dependent on OEMs. In the past, the main engine factory was basically responsible for the design of the leaf spring, and the leaf spring enterprise processed according to the drawing, and now some main engine factories need parts manufacturers to participate in the design and development of products, but on the whole, the speed of new product development is slow, and there is a lack of system management and theoretical support.

The development of new products and new processes in China is very lagging behind, such as air suspension springs; In terms of production equipment, foreign countries have generally adopted automatic online detection methods, the display of test result data, automatic mathematical statistics, automatic feedback adjustment function, automatic pressure sorting and other control methods; The size of the leaf spring, such as height, outer diameter, number of turns, load and flaw detection, is automatically detected, which not only improves production efficiency, reduces scrap rate and rework rate, but also ensures the reliability and stability of product quality. Domestic air suspension spring products are now in the experimental stage.
