Abstract
The invention discloses a composite plate spring with an open integrated eye. The composite plate spring comprises a spring body and an eye. One end of the eye is integrally combined to the spring body. An opening forms between the tail end of the eye and the spring body. The composite plate spring integrating the eye and the spring is in the open-eye design, so that the local deformation and displacement of the eye is insusceptible to the main spring, no accompanying stress is generated, and the composite plate spring is higher in delamination resistance and tamper resistance. The integrated eye at the tail end face of fiber is not connected with the surface of the spring body, so that the eye can rotate and displace in a wider range relative to a shaft connected with the eye with no increase of strain stress, and the composite plate spring is higher in bearing capacity and strength.
Description
Technical field
The invention belongs to and there is the board-like spring of the 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 characteristics such as lightweight, that 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 the 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 have whole composite material link, their manufacture process is also very complicated, and survivability is very low.Fig. 1 has provided several linkage structures commonly used.Shown in Fig. 1 (a) is the coil of strip ear be connected with spring by the bolt screw.Although this connection simple cheap can form stress and concentrate around hole, thereby affect 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 the 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 the 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 failure, the great number of elastic that this destruction discharges can be brought out the delamination failure of spring main body again.
Summary of the invention
The object of the invention 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 present invention is by the following technical solutions:
A kind of board-like spring of composite material with the whole grasswort of open type, comprise that spring body and grasswort form, and an end and the spring body of grasswort are complex as a whole, and between the end of grasswort and spring body, an opening are arranged.
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 between terminal surface a and spring body surface b, angle is arranged.
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 present invention has following advantage: the invention belongs to and have the board-like spring of the composite material that integrates grasswort and spring, adopt the grasswort design of opening, make grasswort not be subject to the restriction of main body spring in local deformation and displacement, the ess-strain of also 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 the spring body surface, this axle that grasswort can be attached thereto relatively has more swing offset, but does not increase ess-strain, thereby has increased bearing capacity and the intensity of composite material spring simultaneously.Traditional leaf spring processing is simple, specialized designs, and the whole grasswort of the present invention safeguards that terminal surface is not connected with the spring body surface, according to the Mechanics of Machinery characteristics design.The present invention 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.
The accompanying drawing explanation
Fig. 1 is traditional board-like spring structure schematic diagram of composite material.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the second structural representation of the present invention.
Fig. 4 is the third structural representation of the present invention.
Embodiment
A kind of board-like spring of composite material with the whole grasswort of open type as shown in Fig. 2-Fig. 4, comprise that spring body 1 and grasswort 2 form, and an end and the spring body 1 of grasswort 2 are complex as a whole, and an opening 3 is arranged 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, between terminal surface a and spring body surface b, angle is arranged, but the distance between the inboard of grasswort terminal surface a and spring body surface b is greater than the distance between the 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 invention is as follows: important superiority of the present invention 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 the main body spring, the ess-strain of also not following produces, thereby has improved the anti-vertical resolution of the board-like spring of composite material.
