Technical Field

The invention relates to the technical field of automobile accessories, in particular to novel automobile disc springs.

Background

The disk spring has the advantages of compact structure size, uniform pressure, non-linearity of load-deformation and the like, and has become an important part of the clutch of the automobile and the tractor, the application of the common disk spring is equivalent to , and the disk spring is suitable for the industries of machinery, metallurgy, electric power, petrochemical industry, mines and automobiles.

However, after the existing common disc spring is formed by blanking, the inner ring and the outer ring of the disc spring are both in a finished circular shape, so that the stiffness of the disc spring is basically equal, namely, the load/displacement curve is linear. The disc spring on the automobile clutch is used for meeting the forward and reverse torque hysteresis values of the automobile clutch after the clutch parts are worn in the period from installation height to service life. When the common disk spring is adopted, the torque lag value of the automobile clutch during installation height is overlarge, or the torque lag value of the automobile clutch after parts of the clutch are abraded is too small, so that the use performance of the automobile clutch is adversely affected.

Therefore, novel automobile disc springs are in urgent need of research.

Disclosure of Invention

In order to solve the problems comprehensively, particularly the defects existing in the prior art, the invention provides novel automobile disc springs which can solve the problems comprehensively.

In order to achieve the purpose, the invention adopts the following technical means:

novel automobile disc spring, including the disc spring body, be equipped with the arc wall on the outer lane of disc spring body, the radian direction of arc wall is inside, the arc wall is equipped with multiunit, multiunit the arc wall circumference distributes.

, the disk spring body is formed by punching and molding a cold-rolled spring steel strip and then performing heat treatment.

The disc spring has the advantages that the elasticity of the disc spring body can be increased through the arrangement, the quality of the disc spring body is improved, and the service life of the disc spring body is effectively prolonged.

, thirty-six groups of arc-shaped grooves are arranged.

The pressure equalizing device has the beneficial effects that thirty-six groups of reasonable distribution can effectively equalize the pressure of the pressure plate, so that the operating force is not increased when the clutch is separated.

, the arc of the arc slot is semi-circular.

The beneficial effect is that the pressing force can be kept basically unchanged after the friction lining surface is worn, and the performance requirement of the clutch on the pressing spring is met.

, the top of the arc slot is set in the middle of the disc spring.

The beneficial effects are that, the effect that this kind of setting can furthest embody the arc wall improves each item performance of belleville spring body.

The invention has the beneficial effects that the radial arc-shaped grooves are uniformly distributed on the outer ring of the disc spring body at intervals, compared with the radial arc-shaped grooves uniformly distributed on the inner ring of the conventional disc spring or disc spring body at intervals, the disc spring generates larger deformation under the same load, the pressure on a pressure plate is uniform, the operating force is not increased when the clutch is separated, and the pressing force can be kept basically unchanged after the friction lining surface is abraded, so that the performance requirement of the clutch on the pressing spring is met, and the invention has the advantages of simple structure, convenience in use, low production cost and easiness in pushing .

As shown in fig. 1 and 2, the invention provides novel automobile disc springs, which comprise a disc spring body 1, wherein an arc-shaped groove 2 is arranged on the outer ring of the disc spring body 1, the radian direction of the arc-shaped groove 2 faces inwards, a plurality of groups of arc-shaped grooves 2 are arranged, and the plurality of groups of arc-shaped grooves 2 are distributed circumferentially.

The disc spring body 1 is formed by punching and forming a spring cold-rolled steel strip and then performing heat treatment. The arrangement can increase the elasticity of the disc spring body 1, improve the quality of the disc spring body 1 and effectively prolong the service life of the disc spring body 1.

Thirty-six groups of arc-shaped grooves 2 are arranged. Thirty-six reasonable groups of distribution can effectively share the pressure of the pressure plate, so that the operating force is not increased when the clutch is disengaged.

The arc of the arc-shaped groove 2 is semicircular. The arrangement can keep the pressing force basically unchanged after the friction lining surface is worn, and meets the performance requirement of the clutch on the pressing spring.

The top point of the arc-shaped groove 2 is arranged in the middle of the disc spring body 1. The setting can embody the function of the arc-shaped groove 2 to the maximum extent and improve various performances of the disc spring body 1.

The invention relates to novel automobile disc springs, which are characterized in that radial arc-shaped grooves are uniformly distributed on the outer ring of a disc spring body at intervals, compared with the radial arc-shaped grooves uniformly distributed on the inner ring of the existing disc spring or disc spring body at intervals, the disc spring generates larger deformation under the same load, the pressure on a pressure plate is uniform, the operating force is not increased when a clutch is separated, and when a friction lining surface is abraded, the pressing force can be kept basically unchanged, so that the performance requirements of the clutch on a compression spring are met.

The foregoing detailed description is given for clarity of illustration only, and is not intended to limit the scope of the invention. It will be apparent to those skilled in the art that other variations and modifications may be made in the foregoing disclosure without departing from the spirit or essential characteristics of all embodiments, and that all changes and modifications apparent from the above teachings are within the scope of the invention.
