Abstract
The utility model discloses a composite material plate spring with an open-type integral spring eye. The composite material plate spring comprises a spring main body and the spring eye, wherein one end of the spring eye is integrally compounded with the spring main body; an opening is formed between the tail end of the spring eye and the spring main body. The utility model belongs to composite material plate springs integrating spring eyes and springs; the design of the open-type spring eye is adopted, so that local deformation and displacement of the spring eye are not restricted by the spring main body, accompanying stress strain is avoided, and accordingly, the delamination resistance and breakage resistance of the composite material plate spring are improved; as the whole spring eye is not connected with the surface of the spring main body on the tail end surface of a fiber, the spring eye can conduct more rotary displacement relative to a shaft connected with the spring eye while the stress strain is not increased, so that the bearing capacity and the strength of the composite material spring are increased.
Description
Technical field
The utility model belongs to and has the board-like spring of composite material that integrates grasswort and spring, can once-through, save time and cost in can also reduce the weight of leaf spring.
Background technique
Engineering material as a kind of advanced person, composite material particularly fibre reinforced composites is progressively replacing traditional engineering material (as metallic material and timber) and is being widely used in the industrial fields such as space flight, aviation, navigation, building, automobile, physical culture and medical apparatus, because this class material has the features such as lightweight, specific stiffness is large, specific strength is high, the life-span is long, corrosion-resistant, designability is good, except for sheet cover, also more and more for structural bearing part.In recent years, composite material plate spring has also obtained application more and more widely.
But current modal composite material spring is two ends uses steel structure to be connected with car body.Even if having whole composite material link, their manufacture process is also very complicated, and survivability is very low.Fig. 1 has provided several conventional linkage structures.Shown in Fig. 1 (a) is the coil of strip ear being connected with spring by bolt screw.Although this connection simple cheap, the surrounding in hole can form stress and concentrate, thereby affects the life-span of spring.In connection shown in Fig. 1 (c) Fig. 1 (d), the two ends of spring have and protrude or recessed profile at width direction, so have the steel hanger of same protrusion or recessed profile, just can be attached thereto.Although this connection has avoided stress to concentrate because need not hole, processing charges increases thereupon.It shown in Fig. 1 (b), is a grasswort structure with spring one.But need reinforcement to avoid cracking at grasswort and spring joint.This grasswort manufacture difficulty and cost are high.Certainly also has the slightly different whole grasswort design of other design, but, the same with the structure shown in Fig. 1 (b), because the two ends of closed grasswort are connected with spring main body, and this connection mainly realizes by body material, and the strength ratio lamination coating of body material is much lower, so interface is easy to destroy, the great number of elastic that this destruction discharges can be brought out the delamination failure of spring main body again.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency a kind of board-like spring of composite material with the whole grasswort of open type is provided, this leaf spring anti-damage performance is strong, and this design can once-through, save time and cost in can also reduce the weight of leaf spring.
For achieving the above object, the utility model is by the following technical solutions:
The board-like spring of composite material with the whole grasswort of open type, comprises that spring body and grasswort form, and one end of grasswort and spring body are complex as a whole, and between the end of grasswort and spring body, have an opening.
The above-mentioned board-like spring of composite material with the whole grasswort of open type, the terminal surface a of described grasswort is a plane, and terminal surface a is parallel with spring body surface b.
The above-mentioned board-like spring of composite material with the whole grasswort of open type, the terminal surface a of described grasswort is a plane, and has angle between terminal surface a and spring body surface b.
The above-mentioned board-like spring of composite material with the carefully and neatly done body grasswort of opening, described grasswort terminal surface a is for being an arc shaped surface.
Adopt technique scheme, the utility model has following advantage: the utility model belongs to and has the board-like spring of composite material that integrates grasswort and spring, adopt the grasswort design of opening, make grasswort in local deformation and displacement, not be subject to the restriction of main body spring, also the ess-strain of not following produces, thereby has improved anti-vertical resolution and the survivability of the board-like spring of composite material.Because the terminal surface of whole grasswort at fiber is not connected with spring body surface, this axle that grasswort can be attached thereto relatively has more swing offset, but does not increase ess-strain simultaneously, thereby has increased bearing capacity and the intensity of composite material spring.Traditional leaf spring processing is simple, specialized designs, and the whole grasswort of the utility model safeguards that terminal surface is not connected with spring body surface, according to Mechanics of Machinery characteristics design.The utility model design is very simple, easy processing, and wherein fibrolaminar laying does not have special arrangement yet, can once-through, thus effectively reduced cost and the weight of composite material spring.

Embodiment
A kind of board-like spring of composite material with the whole grasswort of open type as shown in Fig. 2-Fig. 4, comprises that spring body 1 and grasswort 2 form, and one end of grasswort 2 and spring body 1 are complex as a whole, and have an opening 3 between the end of grasswort 2 and spring body 1.
As shown in Figure 2, the terminal surface a of described grasswort is a plane, and terminal surface a is parallel with spring body surface b.
As shown in Figure 3, the terminal surface a of described grasswort is a plane, and terminal surface a and spring body surface b are not parallel, be to have angle between terminal surface a and spring body surface b, but the distance between the inner side of grasswort terminal surface a and spring body surface b is greater than the distance between grasswort terminal surface outside and spring body surface b.
As shown in Figure 4, the terminal surface a of described grasswort is an arc shaped surface.
Working procedure of the present utility model is as follows: important superiority of the present utility model is its anti-damage performance.Due under the effect of various load, grasswort has local deformation and displacement, thereby the end that makes grasswort changes to the distance on main body spring surface, if the end of grasswort and spring body surface link together, this local deformation and displacement will produce in joint the ess-strain that can cause destruction, and adopt the grasswort of opening to design, make the local deformation of grasswort and the restriction that displacement is not subject to main body spring, also the ess-strain of not following produces, thereby has improved the anti-vertical resolution of the board-like spring of composite material.
