The elastic force of itself has the function that compensator or trimmer pressure, but due to being fitted closely between plate spring sheet, and it is line to wait its property of rigidity leaf spring
Property, it is empty, fully loaded, overload frequency difference it is big, stress be bent when rubs mutually will produce abnormal sound, have an effect on vehicle use the longevity
Life.
It is therefore desirable to design a kind of leaf springs of car, to overcome the above problem.
Utility model content
The purpose of the utility model is to overcome the defect of the prior art, provide a kind of reasonable design, can mitigate abnormal sound,
Improve the leaf springs of car of service life.
The utility model is realized in this way：
The utility model provides a kind of leaf springs of car, including main spring, upper auxiliary spring, lower auxiliary spring and the volume positioned at main spring both sides
Ear is respectively equipped with clip on the inside of the grasswort of main spring both ends, the first gasket is equipped between main spring and clip, the first gasket center is equipped with
Location hole, end are equipped with limiting section, and angle is more than 90 degree between limiting section and the first gasket, and limiting section is equipped with limiting slot；It is main
Spring, upper auxiliary spring and lower auxiliary spring are locked together by middle bolt fastening and locking nut, and upper auxiliary spring and lower auxiliary spring both sides are with fastening
Bolt is fixed with snubber block.
Further, grasswort is flat coiled form grasswort.
Further, middle bolt fastening is made of bolt head, conical section and shank of bolt, and bolt head passes through conical section with shank of bolt
Excessively connection, the big end of conical section is identical as the diameter of bolt head, and small end is identical as the diameter of shank of bolt.
Further, clip includes clamp bolt, casing and clip nut composition.
Further, the second gasket is equipped between upper auxiliary spring and main spring and main spring and lower auxiliary spring.
Further, the first gasket and the second gasket are rubber sheet gasket.
The utility model has the advantages that：
The leaf springs of car reasonable design of the utility model, it is highly practical, effectively reduce friction noise, improve service life with
And the ride comfort in vehicle traveling process.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of leaf springs of car provided by the utility model；
Fig. 2 is the structural schematic diagram of the first gasket provided by the utility model；
Fig. 3 is the side view of the first gasket provided by the utility model；
Fig. 4 is the structural schematic diagram of middle bolt fastening provided by the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs 1-4, the leaf springs of car of the utility model, including main spring 1, upper auxiliary spring 2, lower auxiliary spring 3 and be located at main spring 1
The grasswort 11 of both sides, grasswort 11 is flat coiled form grasswort 11, to reduce the bending stress of grasswort 11.
The inside of 1 both ends grasswort 11 of main spring is respectively equipped with clip 12, and clip 12 includes 12 bolt of clip, casing and clip 12
Nut forms.The first gasket 5 is equipped between main spring 1 and clip 12.First gasket 5 is rectangular parallelepiped structure, and center is equipped with positioning
Hole 51, end are equipped with limiting section 52, and angle is more than 90 degree between limiting section 52 and the first gasket 5, and limiting section 52 is equipped with limit
Slot 53 is caught in convenient for 1 end of main spring, improves efficiency of assembling and restraining ability, solve the first gasket 5 it is easy to wear fall off ask
Topic.
Main spring 1, upper auxiliary spring 2 and lower auxiliary spring 3 are locked together by middle bolt fastening 4 and locking nut, and middle bolt fastening 4 is by spiral shell
Bolt head 41, conical section 42 and shank of bolt 43 form, and are threaded on shank of bolt 43.Bolt head 41 passes through conical section with shank of bolt 43
42 excessively connections, the big end of conical section 42 is identical as the diameter of bolt head 41, and small end is identical as the diameter of shank of bolt 43.Conical section
42 have preferable mechanical property, improve the service life of middle bolt fastening 4, effectively reduce bolt head 41 to carriage bolt location hole
51 abrasion.
