Description
Technical field
The present invention relates to securing member field more particularly to a kind of special-shaped leaf springs of multiple spot carrying in the same direction.
Background technique
Leaf spring belongs to fastener, and subdivision belongs to spring one kind, in detail title leaf spring.One kind for belonging to fastener, for dress
In machine, the resilience part of equipment, play a part of providing linear screen resilience, leaf spring is applied relatively broad on automobile, is also had
Dedicated leaf spring for various equipment.For automobile, by hanging the operating mechanism of vehicle, when vehicle is subjected to the movement in vehicle
When the operating force that period occurs, stability is provided to vehicle.
Leaf spring form is varied, and also comparative maturity, current leaf spring of various shapes are used for different specific fields for development.Fortune
Used for many years with the leaf spring of composite material or composite construction, but be limited at home industrial foundation is sturdy, leaf spring at
The conditions such as type technology is immature, composite material application is not furtherd investigate, matured product also not yet comes into operation extensively at present.Plate
Spring is suitable for the carrying of the axis of automobile, heavy-duty machinery etc., vibration damping, developed at present many high intensity long lifes leaf spring and
A combination thereof part.However, carry situation for many places bearing, then traditional leaf spring may be needed with more or group in some way
It closes, the special-shaped leaf spring adapted in a kind of structure is needed to substitute, to reduce cost, simplify overall structure.
Summary of the invention
The purpose of the present invention is to provide a kind of special-shaped leaf springs of multiple spot carrying in the same direction, are applicable in multiple spot with the improvement in structure
Bearing requirements in situation in the same direction, so as to overcome the problems existing in the prior art.
In order to achieve the goal above, the technical scheme is that
A kind of special-shaped leaf spring of multiple spot carrying in the same direction, it is suitable outward from mainboard spring end including intermediate mainboard spring and several grades
The same level-one subplate spring of the subplate spring of secondary connection, mainboard spring both ends is symmetrical, has main recess on the upside of the mainboard spring, on subplate spring
Side has secondary recess portion, and main recess and all secondary recess portions are in the same direction, between the mainboard spring and the subplate spring of the first order, any phase
There is the enhancing joint of integrally connected between adjacent two subplate springs；Several enhancing joints are connected with volume in main recess or secondary recess portion side
Ear.
Preferably, the mainboard spring and secondary plate spring shape are elliptic arc, the elliptic arc of the mainboard spring or subplate spring
Angle accounts for affiliated elliptical one third or less.Mainboard spring or subplate spring are elliptic arc and account for that its 1/3 or less amount of deflection is suitable, rigidity
Properly.
Preferably, the material of the mainboard spring, subplate spring is fibre-reinforced thermosetting plastics.Fibre-reinforced thermosetting
Property plastics be make leaf spring most suitable material, have the characteristics that high intensity, it is light-weighted.
Preferably, the mainboard spring, subplate spring upper and lower surface all have reinforcing rib.The bending resistance that reinforcing rib reinforces leaf spring is strong
Degree.
Preferably, the series of the subplate spring be 2 ~ 5, and along mainboard spring end toward outside direction subplate spring length by
Grade is successively decreased.The series of subplate spring should not be excessive, not so may easily cause unstability, and 2 ~ 5 grades are that economic suitable quantity is chosen.
The beneficial effects of the present invention are: the configuration of the present invention is simple, multistage subplate spring are applied widely.The structure of leaf spring body
Design is unique, and the design and recess portion of multistage subplate spring are suitable for the situation of more axis in the same direction；Enhancing joint and grasswort are set
It sets and has ensured flexural stability and installation.Structure of the invention is compact, the superposition of multistage leaf spring with to enhance the form that joint connects,
More axis side by side or adjacent to each other can be carried simultaneously, and play Joint vibration reduction, extend the scope of application of leaf spring.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
In figure: 1- mainboard spring, 10- main recess, the end 11-, 2- subplate spring, 20- pair recess portion, 3- enhance joint, 4- grasswort.
Specific embodiment
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, the accompanying drawings in the following description is only as described in this application
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Below with reference to Fig. 1 and specific embodiment, the present invention is furture elucidated.
Such as Fig. 1, a kind of special-shaped leaf spring of multiple spot carrying in the same direction, including intermediate mainboard spring 1 and several grades from 1 liang of mainboard spring
Sequentially connected subplate spring 2, the number of subplate spring 2 are followed successively by level-one ~ final stage subplate spring 2, the mainboard spring 1 outward for a end 11
It is elliptic arc with 2 extending direction curve shape of subplate spring, the oval arc angle of the mainboard spring 1 or subplate spring 2 accounts for affiliated ellipse
Round one third to 1/6th, mainboard spring 1, subplate spring 2 material be fibre-reinforced thermosetting plastics, it is mainboard spring 1, secondary
