Problems solved by technology

When this common disk spring is used, the torque hysteresis value when the automobile clutch is installed at a height is too large, or the torque hysteresis value after the clutch parts are worn is too small, so the performance of the automobile clutch is adversely affected

Abstract

The invention discloses a novel automobile disc-shaped spring. The novel automobile disc-shaped spring comprises a disc-shaped spring body, wherein a plurality of groups of arc-shaped grooves are formed in an outer ring of the disc-shaped spring body. The radian directions of the arc-shaped grooves are inward directions. The plurality of groups of arc-shaped grooves are distributed circumferentially. The novel automobile disc-shaped spring has the beneficial effects that the radial arc-shaped grooves are uniformly distributed at intervals in the outer ring of the disc-shaped spring body; and compared with the condition that an inner ring of an existing disc-shaped spring or disc-shaped spring body is uniformly provided with radial arc-shaped grooves at intervals, large deformation of the disc-shaped spring is generated under the same load, pressure applied to a pressing disc is uniform, and operating force is not increased when a clutch is separated. When a friction lining face is worn, pressing force can be kept basically unchanged, and performance requirements of a clutch for a pressing spring are met. The novel automobile disc-shaped spring is simple in structure, convenient touse, low in production cost and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a novel auto disc spring. Background technique [0002] Disc springs have the advantages of compact size, uniform pressure, and non-linear load-deformation, and have become important parts of clutches in automobiles and tractors. Ordinary disc springs are widely used in machinery, metallurgy, electric power, petrochemical, mining and automobile industries. [0003] However, after the existing common disc spring blanking is formed, the disc spring inner ring and outer ring are all completed circles, so the stiffness of the disc spring is substantially equal stiffness, that is, the load / displacement curve is linear. The purpose of the disk spring on the automobile clutch is to meet the forward and reverse torque hysteresis value of the automobile clutch after the wear of the clutch parts from the installation height to the service life. When adopting this common disc spring, t...
