Abstract
A variable-stiffness light automotive rear plate spring is mainly composed of a main plate spring piece I, a main plate spring piece II, a plate spring piece I, a plate spring piece II, a variable cross-section plate spring piece, a bolt I, a plate spring clip, a bolt II, a rivet and a plate spring holding clip. The variable-stiffness light automotive rear plate spring is characterized in that the main plate spring piece I, the main plate spring piece II, the plate spring piece I, the plate spring piece II and the variable cross-section plate spring piece are overlaid sequentially and are tightly connected through the bolt I at symmetrical central positions. The variable cross-section plate spring piece, the main plate spring piece I, the main plate spring piece II, the plate spring piece I and the plate spring piece II are clamped together by the plate spring clip through the rivet on end portion of the variable cross-section plate spring piece and are fixed through the bolt II. The plate spring holding clip is fixed on the end portion of the plate spring piece II, an dafter the end portion is bent, the plate spring piece II, the main plate spring piece I, the main plate spring piece II and the plate spring piece I are bound together and fixed through the bolt II. The variable stiffness is formed for the non-combining face of the variable cross-section plate spring piece in such a way that the face becomes thinner towards two ends in an arc mode. The variable-stiffness light automotive rear plate spring has the advantages of being simple in structure, light in weight and capable of achieving light weight of light automobiles easily.
Description
Technical field
The utility model belongs to automobile manufacturing field, relates in particular to leaf spring behind a kind of change rigidity light-duty vehicle.
Background technique
On the similar light-duty vehicles such as low-speed truck, the rear overhang rack leaf spring adopts the stiffness steel plate springs such as uniform section mostly, although it is large to have rigidity, and the characteristics that overload capacity is strong, complex structure, and relatively heavier.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that exists in the prior art and leaf spring after a kind of change rigidity light-duty vehicle is provided.
The technological scheme that its technical problem that solves the utility model adopts is to implement like this: leaf spring behind a kind of change rigidity light-duty vehicle, mainly embracing folder by mainboard reed I, mainboard reed II, plate spring sheet I, plate spring sheet II, board of variable section reed, bolt I, bridle, bolt II, rivet, leaf spring forms, it is characterized in that: a. is superimposed mainboard reed I, mainboard reed II, plate spring sheet I, plate spring sheet II, board of variable section reed successively, uses bolt I and stressed joint at the symmetry center position; B. the end of board of variable section reed is fixed with bridle by rivet, after by bridle board of variable section reed, mainboard reed I, mainboard reed II, plate spring sheet I, plate spring sheet II being clipped together, fixes with the bolt II; C. the end of plate spring sheet II is fixed with leaf spring by rivet and embraces folder, and leaf spring after embracing the folder bending bundles plate spring sheet II, mainboard reed I, mainboard reed II, plate spring sheet I, fixes by the bolt II; D. bridle, leaf spring are embraced folder and are symmetrical fixing, and non-binding of board of variable section reed is gradually thin to the two ends gradual change with circular arc, form and become rigidity.
The utlity model has simple in structurely, lightweight, be easy to realize the light-weight design of light-duty vehicle.
Description of drawings
Fig. 1 is the plan view of the utility model structure.
Among the figure: 1. mainboard reed I, 2. mainboard reed II, 3. plate spring sheet I, 4. plate spring sheet II, 5. board of variable section reed, 6. bolt I, 7. bridle, 8. bolt II, 9. rivet, 10. leaf spring is embraced folder.
Embodiment
As shown in Figure 1, leaf spring behind a kind of change rigidity light-duty vehicle, mainly embracing folder 10 by mainboard reed I1, mainboard reed II 2, plate spring sheet I3, plate spring sheet II 4, board of variable section reed 5, bolt I6, bridle 7, bolt II 8, rivet 9, leaf spring forms, it is characterized in that: a. is superimposed mainboard reed I1, mainboard reed II 2, plate spring sheet I3, plate spring sheet II 4, board of variable section reed 5 successively, uses bolt I 6 and stressed joints at the symmetry center position; B. the end of board of variable section reed 5 is fixed with bridle 7 by rivet 9, and is after bridle 7 is clipped together board of variable section reed 5, mainboard reed I1, mainboard reed II 2, plate spring sheet I3, plate spring sheet II 4, fixing with bolt II 8; C. the end of plate spring sheet II 4 is fixed with leaf spring by rivet 9 and embraces folder 10, and leaf spring after embracing folder 10 bendings bundles plate spring sheet II 4, mainboard reed I1, mainboard reed II 2, plate spring sheet I3, and is fixing by bolt II 8; D. bridle 7, leaf spring are embraced folder 10 and are and are symmetrical arranged, and non-binding of board of variable section reed 5 is gradually thin to the two ends gradual change with circular arc, forms to become rigidity.
The utlity model has simple in structurely, lightweight, be easy to realize the light-weight design of light-duty vehicle.
