Description
Technical field
This utility model relates to spring for motor car series assembly, specifically a kind of variable-section steel sheet spring assembly.
Background technology
Leaf spring is a vitals in vehicle suspension system, under the overall situation of energy-saving and emission-reduction, heavily stressed light-weighted few sheet variable-section steel sheet spring obtains and is increasingly widely applied, few-leaf-spring assembly conventional at present is to be fitted together by certain prestress by several monolithics by centre bolt or U-bolt, direct basis between each end, or end is provided with the noise reduction piece of engineering plastics material.In use due to the deformation vibration of leaf spring, between each, occur that the plate spring sheet that relative motion, end directly contact easily produces noise；Being provided with engineering plastics noise reduction piece plate spring assembly and also do not continue due to engineering plastics earlier period damage noise reduction, simultaneously because leaf spring dynamic stiffness is relatively big, the general comfortableness of leaf spring car is not so good.Now with popularization and the application of integral new-energy passenger, the client's further raising to requiring by bus, leaf spring car particularly passenger vehicle requires more and more higher for noise and the comfortableness of leaf spring.
A kind of new steel plate main assemblage of spring of CN2014208399513, it is adaptable to the leaf spring that uiform section is long-pending.
A kind of steel plate spring assembly of CN2014208399513, is simultaneously used liner and noise reduction piece, and batch is for bus market.
Two above patent does not have to solve well the comfortableness of variable-section steel sheet spring product.
Summary of the invention
This utility model, in order to eliminate the reliability using noise and raising noise reduction that each direct contact of variable-section steel sheet spring causes, improves comfortableness, a kind of variable-section steel sheet spring assembly of special proposition simultaneously.
For this technical solution of the utility model it is: a kind of variable-section steel sheet spring assembly, including variable-section steel sheet spring group, the center of variable-section steel sheet spring group is to be fitted together by prestress by multiple monolithic variable-section steel sheet springs by centre bolt and nut, described multiple monolithic variable-section steel sheet spring ends are processed by press-bending, and are fixed as one by U-bolt in end；Wherein the end of the superiors' variable-section steel sheet spring is provided with grasswort, is provided with lining in grasswort, and the end of middle variable-section steel sheet spring scrolls up into radian, and grasswort is formed enclosed structure, and the end of bottom variable-section steel sheet spring is straightway.
Further it is improved by: between each monolithic variable-section steel sheet spring of variable-section steel sheet spring group switching centre, be provided with liner.
Further it is improved by: between each monolithic variable-section steel sheet spring end, be provided with damping rubber block, and with U-bolt, end is fixed, in the middle of wherein, the end of variable-section steel sheet spring is provided with through hole up and down, and damping rubber block is by through hole by filling and vulcanization between each monolithic variable-section steel sheet spring end integrally.
Beneficial effect:
A kind of variable-section steel sheet spring assembly provided in this utility model, suitable in passenger vehicle, both the good fit of leaf spring end plane had been ensured, also improve the stress distribution between reed simultaneously, improve the reliability of plate spring assembly, contour structures is simple, and the mounting means with current traditional leaf spring is consistent, can realize directly replacing.
It is provided with liner between each monolithic variable-section steel sheet spring of variable-section steel sheet spring group switching centre, reduces noise, improve comfort level；In the middle of leaf of spring, install liner additional, facilitate assembling and the fastening of U-bolt.
End increases damping rubber block and processes, and namely adopts at middle spring end the modes such as through hole location, sulfuration, splicing to add an elastic block rubber, adopts press-bending to process leaf spring monolithic end simultaneously；Both ensure the good fit of elastic block rubber and leaf spring end plane, also improved the stress distribution between reed simultaneously, improve the reliability of plate spring assembly.
This utility model adds damping rubber block due to the end at leaf spring, makes up each relative motion in use produced of leaf spring by the creep of rubber, completely eliminates the use noise that ends contact friction causes；Be ensure that the good fit of reed and damping rubber block simultaneously by leaf end press-bending structure, improve the stress distribution of reed, improve the reliability of plate spring assembly；Friction between leaf spring can result in the elastomer between leaf of spring and produces creeping deformation, reduces the dynamic stiffness of leaf spring, improves riding comfort.
This utility model fundamentally solves the noise that few sheet variable-section steel sheet spring produces；It is greatly improved reliability and the riding comfort of few sheet variable-section steel sheet spring simultaneously.
