Abstract
A variable-cross-section steel plate spring with gradually-changing rigidity comprises a main reed, an auxiliary reed and a gasket. One end of the main reed is provided with an upper roll lug, a Berlin type roll lug is arranged at the other end of the main reed, the two roll lugs are bent oppositely, linings are sleeved on the two roll lugs, a kidney-shaped hole punching round counter bored hole is formed in the main reed, a kidney-shaped hole punching round protrusion is arranged on the auxiliary reed, and the kidney-shaped hole punching counter bored hole and the kidney-shaped hole punching round protrusion are matched, the gasket is arranged under the auxiliary reed, and the main reed and the auxiliary reed are connected with nuts through central bolts. The variable-cross-section steel plate spring is of a composite structure of the main reed and the auxiliary reed and effectively improves driving smoothness and riding comfortableness. The main reed and the auxiliary reed are fixed in a mode that the kidney-shaped hole punching counter bored hole and the kidney-shaped hole punching round protrusion are matched. A rivet hole punching process and accessories for connecting clamping hoops are removed so as to effectively reduce production cost. The linings of the two roll lugs are rubber composite linings, can prevent movement between the linings and the hole diameters of the roll lug and effectively reduce noise.
