Description
Technical Field
The invention belongs to the technical field of plate spring preparation, and particularly relates to a preparation method of a composite plate spring.
Background
The leaf springs are long circular arc shaped spring steel with a rectangular cross section, the center of the arc providing the location of the axle in the most common configuration, and the ring formed at either end attached to the vehicle chassis, for very heavy vehicles leaf springs can be made from multiple blades stacked together, usually with progressively shorter blades, which can be used for positioning and a degree of damping as well as spring function, although sandwich friction provides damping, but it does not control well and results in static friction in suspension motion.
Leaf spring can lug connection on the frame at both ends, or lug connection is in one end, and the front end usually, the other end passes through the shackle, and the short swing arm is connected, and the elasticity has brought the trend of blade extension when the compression to make elasticity softer, traditional leaf spring quality is heavier, and the antifatigue characteristic is less strong, and fatigue life is lower.
