Description
Technical field
The utility model relates to field of automobile shock absorption, relates to a kind of leaf springs of car with efficient shock-absorbing function specifically.
Background technology
The car body damping of current automobile, the general leaf spring that all uses reaches the object of damping, the primary member of leaf spring is plate spring sheet, leaf spring clip and bolt, the length of plate spring sheet is stepped successively decreases, it is an entirety that leaf spring is connected by bolt and leaf spring clip, the plate spring sheet length of the superiors is maximum, bends out hanger at its two ends, for being installed on below car body by leaf spring.When leaf spring is stressed, utilize the elastic force of leaf spring self, reach the effect of compensator or trimmer pressure, but due to etc. its character of rigidity leaf spring be linear, when automobile is unloaded, fully loaded, overload time, the leaf spring natural frequency of vibration differs greatly, in the process of moving and easily produce friction between leaf spring reed, there is abnormal sound in not only working, and reduce life of plate spring, affect car load service life; And the many assembly processes of plate spring sheet are complicated, labour intensity is large, productive costs is high, prior art such as all to adopt at the rigidity leaf spring, the problem of sky, fully loaded, the overload natural frequency of vibration cannot be solved, and leaf spring constantly rubs between driving process reed, not only has Abnormal Sound, and life of plate spring is generally lower.
Utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology, and provide a kind of reasonable in design, structure is simple, function admirable, uses reliable, the leaf springs of car easily manufactured.
The technical solution adopted in the utility model is: a kind of leaf springs of car with efficient shock-absorbing function, comprise main spring, upper auxiliary spring, lower auxiliary spring and bolt, described bolt is by main spring and upper auxiliary spring, lower auxiliary spring is fixed together, described main spring is made up of superpose up and down two long reeds, the inner side of described main spring two ends hanger is respectively equipped with leaf spring clip, described leaf spring clip is by clamp bolt, sleeve pipe, nut forms, described main spring bottom is provided with lower auxiliary spring, the curved structure of reed of described lower auxiliary spring, described main spring top is provided with auxiliary spring, described upper auxiliary spring be provided with two pads superposed up and down between main spring, described upper auxiliary spring is made up of three reeds superposed up and down, three length of spring leaf are successively decreased from top to bottom, also unit of plastic is provided with between described upper auxiliary spring and main spring, the surface of described main spring is provided with carbon fiber integument.
Preferably, also unit of plastic is provided with between described lower auxiliary spring and main spring.
Preferably, described hanger has a gap structure.
Preferably, be also formed with block between described main spring and upper auxiliary spring, described block is mobily connected in described main spring towards on the face of upper auxiliary spring.
Preferably, be also formed with block between described main spring and lower auxiliary spring, described block is mobily connected in described main spring towards on the face of lower auxiliary spring.
Preferably, the surface of described unit of plastic is provided with nanometer layer.
Advantage of the present utility model and beneficial effect are: owing to having gap between auxiliary spring and main spring, and time unloaded, only main spring works, and auxiliary spring is in no load state; When fully loaded, main spring bears fully loaded load together with auxiliary spring.The utility model is rational in infrastructure, and technique is simple, easy to manufacture, and cost is low, dependable performance, effectively can improve the service life of ride comfort in vehicle traveling process and automobile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, hanger, 2, main spring, 3, lower auxiliary spring, 4, upper auxiliary spring, 5, bolt, 6, leaf spring clip.
Detailed description of the invention
Be further described detailed description of the invention of the present utility model below in conjunction with drawings and Examples, following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, for structural representation of the present utility model, the leaf springs of car of the present embodiment comprises main spring 2, lower auxiliary spring 3, upper auxiliary spring 4, bolt 5, bolt 5 is by main spring 2, lower auxiliary spring 3, upper 4 link together, its main spring 2 is made up of two the long reeds superposed up and down, the inner side of main spring 2 two ends hanger 1 has leaf spring clip 6 respectively, leaf spring clip 6 is by clamp bolt, sleeve pipe, nut forms, lower auxiliary spring 3 is provided with in main spring 2 bottom, the curved two ends of lower auxiliary spring 3 reed is bent downwardly, auxiliary spring 4 is provided with on main spring 2 top, two pads superposed up and down are provided with between upper auxiliary spring 4 with main spring 2, upper auxiliary spring 4 is made up of three reeds superposed up and down, three length of spring leaf are successively decreased from top to bottom.
Preferably, between described lower auxiliary spring and main spring, be also provided with unit of plastic, reduce the friction between reed.Also be provided with unit of plastic between described upper auxiliary spring and main spring, the surface of described main spring is provided with carbon fiber integument.
Preferably, the surface of described main spring is provided with carbon fiber integument, because the material of carbon fiber is comparatively light, and rub resistance, thus the service life extending reed.
Preferably, be also formed with block between described main spring and upper auxiliary spring, described block is mobily connected in described main spring towards on the face of upper auxiliary spring, thus can adjust the gap between main spring and upper auxiliary spring.
Preferably, be also formed with block between described main spring and lower auxiliary spring, described block is mobily connected in described main spring towards on the face of lower auxiliary spring, thus can adjust the gap between main spring and lower auxiliary spring.
Preferably, described protective cover is nanometer layer.
Owing to having gap between auxiliary spring and main spring, time unloaded, only main spring works, and auxiliary spring is in no load state; When fully loaded, main spring bears fully loaded load together with auxiliary spring.At full load, due to main spring and auxiliary spring one side fluted, the friction of concave surface hardened layer is reduced, its fatigue resistance can be improved.The utility model is rational in infrastructure, and technique is simple, easy to manufacture, and cost is low, dependable performance, effectively can improve the service life of ride comfort in vehicle traveling process and automobile.At full load, due to main spring and auxiliary spring one side fluted, the friction of concave surface hardened layer is reduced, its fatigue resistance can be improved.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
