Description
Technical field
The utility model relates to vapour vehicle elastic element technical field, is specifically related to a kind of steel plate spring assembly of corner cut.
Background technique
Automobile leaf spring is the at present domestic and international main elastic element of automobile suspension system, in service at automobile, transmitting the power and the moment that act on all directions between vehicle frame and vehicle body, alleviate because pass to the impulsive load of vehicle body in Uneven road and different loads situation by tire, alleviate the vibrations of vehicle body, have positive effect the working life of the smoothness of automobile running, the travelling comfort that frame is taken advantage of personnel, the stability carrying cargo and raising automobile associated components to ensureing.
The leaf spring that current all types of automobile uses, most leaves of spring end is processed or only carries out simple corner cut processing and process without any processing, each end of this leaf spring do not have optimization process for further processing, for the plate spring assembly of more than two spring sheet composition, when in the process that automobile is travelling, uneven along with road surface, the each as easy as rolling off a log stress mutation phenomenon that occurs in end, this sudden change must cause the undue concentration of the stress of spring end, and can produce the relative changing of the relative positions between the spring sheet of load, cause the damage between adjacent springs sheet, thereby reduce the life-span of leaf spring, there is larger variation with the variation of load in the eigentone of vehicle body vehicle body in the process of moving simultaneously, travelling comfort stationarity is poor.Therefore, how to provide a kind of leaf spring, concentrate with the stress that reduces spring end, the vibrations that improve working life and alleviation vehicle body become those skilled in the art's important technological problems urgently to be resolved hurrily.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of stress distribution evenly, improve leaf spring working life, and alleviate the steel plate spring assembly of the corner cut of vehicle body vibrations.
In order to solve the problems of the technologies described above, the utility model provides a kind of steel plate spring assembly of corner cut, comprise mutual stack spring sheet composition the first deformation spring and be arranged on the second deformation spring of the first deformation spring below, described the first deformation spring is connected by fixing-assembly with the middle part of the second deformation spring, the length of described spring sheet is successively decreased from top to bottom successively, end, the two ends corner cut of described spring sheet, in the relative one side of the corner cut of spring sheet, be provided with the card rib groove that cross section is circular arc, on the relative another side of card rib groove, be provided with the fin coordinating with the card rib groove of adjacent springs sheet.
Adopt the steel plate spring assembly tool of the corner cut of technique scheme to have the following advantages: by the fin on spring sheet being arranged in the card rib groove of the circular arc on adjacent springs sheet, because making the thickness of the end of spring sheet, the spring sheet of corner cut reduces, improve the stress of contact position, spring sheet end, reduced respectively the stress of the first deformation spring and the second deformation spring end and concentrated, when the spring sheet cross section of corner cut, integrity is destroyed, stress is concentrated relevant with cross-sectional shape feature, therefore, the fin that adopts cross section to be the card rib groove of arc-shaped structure and to coordinate with the card rib groove of adjacent springs sheet, round and smooth shape increases the surface of contact while cooperation between adjacent two spring sheets, contribute to make stress concentration phenomenon to tend towards stability simultaneously, make stress distribution even, and fin and card rib groove cooperatively interact make load spring sheet and adjacent between spring sheet be connected more firm, in the local time that automobile running is rough on road surface, effectively avoid producing between the spring sheet of load the situation of the relative changing of the relative positions, improve the working life of leaf spring, further, when the load-carrying load bearing when the first deformation spring and the second deformation spring changes respectively, the power that the spring sheet of corner cut bears also changes thereupon, superincumbent spring sheet can produce different deformation along with the difference of the power of bearing, and by fin and card rib groove by close-connected structure between upper and lower spring sheet and spring sheet, contribute to alleviate the vibrations of vehicle body, improve driver and passenger's travelling comfort.
As preferred version, consider the size that changes gradually the stress that the effect length in corner cut cross section will improve, the angle of inclination of described corner cut is 45 degree.
As preferred version, for the setting of convenient card rib groove, described card rib groove is arranged on apart from the spring sheet end 2～5cm of place.
As preferred version, in order to facilitate the connection of the first deformation spring, and make spring sheet in the time of the first deformation spring distortion have the possible of relative sliding, described the first deformation spring also comprises that end arranges the first linking springs sheet of grasswort and the second spring sheet that the first linking springs sheet below arranges, second end, spring sheet one end arranges the bag ear that grasswort is encased, and leaves the space of 3～5cm between grasswort and bag ear.
As preferred version, in order to prevent the dislocation of spring sheet of the first deformation spring, each spring sheet both sides of described the first deformation spring adopt clamp to fix.
As preferred version, for convenient fixing, bolt centered by described fixing-assembly.
