1. Purpose:

    Mechanical leaf spring fatigue testing machine is mainly used to test the fatigue life of automobile leaf spring assembly. By replacing the test aids, it can also test various coil springs and various parts used in automobiles, motorcycles, and other vehicles. Fatigue life test.

2. Structural features of mechanical leaf spring fatigue testing machine :

(1) The main body adopts a "C-shaped" structure, the force is enclosed inside the body, and there is basically no basic requirement. The fuselage is a steel plate welded structure with high overall strength and a smooth and beautiful appearance.
(2) The main transmission system adopts two-stage reduction transmission: the first stage is belt transmission, and the passive pulley doubles as an inertia wheel, which has a higher speed to increase the inertial energy storage and significantly reduce the power of the drive motor; the second stage It is a gear drive.
(3) In the first-stage transmission mechanism, a pneumatic clutch is installed to ensure that the motor starts under no load. Pneumatic clutch has the advantages of safety, reliability and long-distance operation.
(4) A worktable that can be lifted as a whole is designed to facilitate the clamping of the leaf spring assembly in a free state, and then apply pre-deformation through the lifting/lowering worktable. The maximum lifting height of the worktable is 200mm. For the leaf spring assembly with a small total height, the clamping position is adjusted by the screw. Auxiliary supports are added at both ends of the workbench, and safety nets are provided. It is equipped with 2 mobile trolleys with accessories for the trolley to be fixed in the working section.
