Description
Technical field
The utility model relates to automobile suspension system technical field, is specifically related to a kind of buffer block structure.
Background technology
Suspension system is the general name of vehicle frame and the stressed connecting device between vehicle bridge or wheel of automobile, its function is the force and moment of transfer function between wheel and vehicle frame, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, and the vibration that decays and cause thus, to guarantee that automobile is smooth-going, travel.
In suspension system, because being hit, elastic element produces vibration, for improving vehicle running smoothness, suspension is conventionally in parallel with elastic element, and steel spring is elastic element traditional in automobile suspension system, due to its good reliability, simple in structure, manufacturing process flow is short, cost is low and structure such as can simplify greatly at the advantage, thereby be widely used.
When carload lot is excessive, in order to prevent that steel spring from colliding with vehicle frame because stroke is excessive, need to be between steel spring and vehicle frame reload buffer piece.Bump rubber of the prior art conventionally adds rubber by whole rubber or pressed sheet skeleton and forms, sort buffer piece is because rigidity value is larger, buffer attribute curve when work rises fast, pooling feature is poor, thereby has influence on NVH (noise, vibration harmony make an uproar the english abbreviation of roughness) and the travelling comfort of car load.
Utility model content
The purpose of this utility model is to provide a kind of buffer block structure, by the monnolithic case to bump rubber, redesign, with solve in prior art because of the rigidity value of bump rubber compared with cause greatly buffer attribute curve rise fast, pooling feature is poor, NVH and the poor problem of travelling comfort of car load.
For achieving the above object, the utility model provides following technical scheme:
A buffer block structure, is arranged between steel spring and vehicle frame, comprises metallic support and rubber pad; Described metallic support is " U " character form structure, and the bottom face of described " U " character form structure and the top end face of described rubber pad are fixed together; On described rubber pad, be provided with a plurality of through holes.
Preferably, in both sides, the top outwardly extending portion of described " U " character form structure, be provided with fixed orifice, described metallic support is fixedly connected with vehicle frame by the binding bolt through described fixed orifice.
Preferably, described metallic support and described rubber pad are sulfuration integrated formed structure.
Preferably, described rubber pad is figure of eight structure, and described through hole is evenly arranged in the two ends up and down in described figure of eight structure.
Preferably, described through hole is rhombus.
The beneficial effects of the utility model are:
Buffer block structure of the present utility model, is arranged between steel spring and vehicle frame, comprises metallic support and rubber pad; Metallic support is " U " character form structure, and the bottom face of " U " character form structure and the top end face of rubber pad are fixed together; On rubber pad, be provided with a plurality of through holes.By the monnolithic case to bump rubber, redesign, the integral rigidity value that a plurality of through holes reduce bump rubber is set on rubber pad, increase the buffer capacity of bump rubber, its characteristic curve is changed more steady, further improve NVH and the travelling comfort of car load.
Further, in both sides, the top outwardly extending portion of " U " character form structure, be provided with fixed orifice, metallic support is fixedly connected with vehicle frame by the binding bolt through fixed orifice, be conducive to fix by 2 fixing replacement single-points of the prior art, what make that bump rubber can be more firm is fixed on vehicle frame, and 2 the fixing impact load stresss that steel spring can also be brought are further distributed on vehicle frame, reduce the excessive damage that vehicle frame is caused of moment stress, extend the whole service life of suspension system.
Further, metallic support and rubber pad are sulfuration integrated formed structure, are conducive to, by simplifying the molding mode of bump rubber, reduce productive costs, are convenient to manufacture in enormous quantities.
Further, rubber pad is figure of eight structure, and through hole is evenly arranged in the two ends up and down in figure of eight structure, and through hole be shaped as rhombus.Be conducive to the expansion performance that utilizes figure of eight structure similar to spring, by the rhombus through hole that the arranges impact load stress of dispersed steel laminated spring successively, make the load deformation characteristic curve of bump rubber become milder above.So not only can allow finally be applied to that stress on vehicle frame diminishes or variation is loose, and further service life of Promoting Layered Buffer piece.
