Abstract

The invention relates to a leaf spring with gradually-varied rigidity, which comprises at least one primary spring sheet and at least one secondary spring sheet, wherein the primary spring sheet and the secondary spring sheet are fixed by a central bolt; the central bolt is positioned in the centers of the primary spring sheet and the secondary spring sheet; a central nut is sleeved on the central bolts; clamp hoops are arranged on both sides of the central bolt on the primary spring sheet; clamp hoop bolts are arranged on the clamp bolts; a clamp sleeve is also sleeved on the primary spring sheet; and different rigidities and axis moments of the primary spring sheet and the secondary spring sheet can be selected. The leaf spring has a simple structure, high elasticity, long service life and good smoothness, and has the equifrequent property.

Description

technical field [0001] The invention relates to an elastic element, in particular to a gradually changing steel degree spring used in a car suspension system whose steel degree changes with the change of load on a minibus. Background technique [0002] In recent years, with the rapid development of the national economy, the domestic automobile industry has gradually become the leading pillar industry. With the substantial growth of domestic automobile production and sales, domestic automobile technology is also being improved through technology introduction and other means. At the same time, users have higher and higher requirements for various performances of automobiles. The ride comfort of the car is one of the important performance indicators of the whole vehicle. It not only ensures the comfort of the passengers and the integrity of the cargo, but also improves the transportation productivity of the car, reduces fuel consumption, and improves the service life of parts. ...
