Description
Technical field
The utility model relates to a kind of automobile leaf spring assembly, is specifically related to a kind of passenger vehicle two stage stiffness variable-section steel sheet spring assembly.
Background technique
Automobile leaf spring is the primary resilient element in automobile chassis suspension system, and it flexibly couples together vehicle frame and axletree.Main task transmits all force and moments acted between wheel and vehicle frame, and the impulsive load, the attenuate shock load that relax uneven road surface cause system vibration.Along with development and the progress of automobile industry, the riding comfort and the pollution of reduction noise circumstance that improve automobile will be the main trend of Future Development.
Current passenger vehicle many employings single-leveled rigidity structural type, i.e. constant rigidity under zero load, semi-load and full load conditions, under there are full load conditions, the moderate smoothness of offset frequency is better taken comparatively comfortable; When zero load and semi-load, comparatively high ride difference riding comfort is poor for offset frequency.
Summary of the invention:
The purpose of this utility model is to provide a kind of passenger vehicle two stage stiffness variable-section steel sheet spring assembly, can improve riding comfort when vehicle zero load and semi-load, to overcome Problems existing in background technique.
To achieve these goals, the technical solution of the utility model is:
A kind of passenger vehicle two stage stiffness variable-section steel sheet spring assembly, comprise main reed and auxiliary spring sheet, main reed and auxiliary spring sheet center have center hole, and linked together by central fastener, main reed is positioned at the top of auxiliary spring sheet; Main reed and auxiliary spring sheet are arc-shaped concave reed, and the thickness of main reed and auxiliary spring sheet reduces to both sides along its length gradually from center, and the radian of main reed is greater than the radian of auxiliary spring sheet; The two ends of main reed are provided with the grasswort for connecting vehicle frame, and be provided with intermediate washer between main reed and auxiliary spring sheet, the two ends of auxiliary spring sheet are provided with elastic cushion block.
Preferably, comprise at least three main reeds, each main reed center alignment superposition is arranged, and the main reed two ends of the top are provided with grasswort.
Preferably, center pad is provided with in center between each main reed.
Preferably, each main reed two ends are provided with noise reduction piece mounting hole.
Preferably, the position near two ends of three main reeds is fastening by clip.
Preferably, clip is fixedly connected on undermost main reed by rivet.
Preferably, the two ends of auxiliary spring sheet are provided with elastic cushion block mounting hole.
Preferably, elastic cushion block is connected to the two ends of auxiliary spring sheet by fastening piece.
A kind of passenger vehicle two stage stiffness variable-section steel sheet spring assembly of the present utility model, in the course of the work, main reed effect when zero load and half cargo condition, use rigidity is main reed rigidity.Start Contact Pair elasticity of spring leaf cushion block along with load increases main reed, auxiliary spring sheet starts to participate in work, uses rigidity for the complex stiffness after main reed and the superposition of auxiliary spring sheet.As mentioned above when empty, half cargo condition, rigidity is only main reed rigidity, reduce this state offset frequency value and improve sky, semi-load vehicle smoothness, improve the travelling comfort taken.Plate spring sheet two end part all placed noise reduction piece and elastic cushion block avoids the noise pollution produced when reed Contact moves.The utility model structure is simple, and cost is low, is easy to carry out, and effectively improves riding comfort when vehicle zero load and semi-load.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model embodiment,
In figure: the main reed of 1-, 2-elastic cushion block, 3-noise reduction piece, 4-auxiliary spring sheet, 5-intermediate washer, 6-central fastener, 7-clip fastening piece, 8-clip, 9-rivet, 10-grasswort.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of passenger vehicle two stage stiffness variable-section steel sheet spring assembly, comprises main reed 1 and auxiliary spring sheet 4, comprises at least three main reeds 1, and each main reed 1 center alignment superposition is arranged; Each main reed 1 and auxiliary spring sheet 4 center have center hole, and linked together by central fastener 6, main reed 1 is positioned at the top of auxiliary spring sheet 4; Be provided with center pad in center between each main reed 1, be provided with intermediate washer 5 between main reed 1 and auxiliary spring sheet 4, each main reed 1 two ends are provided with noise reduction piece 3 mounting hole, can just be arranged on wherein by noise reduction piece 3, reduce noise;
The position near two ends of three main reeds 1 is fastening by clip 8, and clip 8 is fixedly connected on undermost main reed 1 by rivet 9, is also provided with clip fastening piece 7 in addition by fastening for clip 8.
The two ends of auxiliary spring sheet 4 are provided with elastic cushion block 2 mounting hole, and elastic cushion block 2 is arranged on wherein, and is connected to the two ends of auxiliary spring sheet 4 by fastening piece.
Main reed 1 and auxiliary spring sheet 4 are arc-shaped concave reed, and the thickness of main reed 1 and auxiliary spring sheet 4 reduces to both sides along its length gradually from center, the variable section structure of convergence iso-stress beam, and the radian of main reed 1 is greater than the radian of auxiliary spring sheet 4; Main reed 1 two ends of the top are provided with the grasswort 10 for connecting vehicle frame, and the two ends of auxiliary spring sheet 4 are provided with elastic cushion block 2.
Passenger vehicle two stage stiffness variable-section steel sheet spring assembly of the present utility model, in the course of the work, when zero load and half cargo condition, main reed 1 acts on, and use rigidity is main reed 1 rigidity.Start Contact Pair reed 4 elastic cushion block 2 along with load increases main reed 1, auxiliary spring sheet 4 starts to participate in work, uses rigidity for the complex stiffness after main reed 1 and auxiliary spring sheet 4 superposition.As mentioned above when empty, half cargo condition, rigidity is only main reed 1 rigidity, reduce this state offset frequency value and improve sky, semi-load vehicle smoothness, improve the travelling comfort taken.Plate spring sheet two end part all placed noise reduction piece 3 and elastic cushion block 2 avoids the noise pollution produced when reed Contact moves.
