Description
Technical field
The utility model is related to a kind of automobile leaf spring more particularly to a kind of wave uniformsection leaf springs.
Background technology
Leaf spring is current automobile suspension system primary resilient element both at home and abroad, in the operation of automobile, transmits work
For the power and torque between vehicle frame and vehicle body, alleviate the shock loading for passing to vehicle body by tire due to Uneven road, delay
The vibrations of vehicle body are solved, comfort, the stability for delivering cargo and the raising of personnel are multiplied to the ride comfort, the frame that ensure running car
The service life of automobile associated components suffers from positive effect.
The design alternative of leaf spring, primarily to meeting the requirement of vehicle ride performance, also in order to meeting leaf spring
The requirement of offset frequency, the height of offset frequency depends on the rigidity and load of Leaf Spring Suspension, since the burden requirement of vehicle is fixed
, the height of offset frequency depends on the rigidity of Leaf Spring Suspension, however the place that entire vehicle design can be reserved to plate spring suspension brackets is limited,
And often heel piece is with very big relationship for leaf spring its rigidity, when main leaf length is smaller, rigidity is often very big, offset frequency
Higher, the comfort of vehicle ride, ride performance are poor, and common uniformsection leaf spring heavier-weight, rigidity is big, comfort
Difference, longitudinal size is longer, is unfavorable for shortening the front overhang and rear overhang of automobile, easy to wear with the spring piot of vehicle frame junction,
Service life is shorter.
Utility model content
In order to solve problem of the prior art, the utility model provides a kind of wave uniformsection leaf spring, it
In the performance basis for keeping raw steel flat spring, change the planform of original leaf spring, enable in the shorter feelings of installation length
Under condition, rigidity in need is gathered around, the offset frequency so as to be needed, and then improve the ride comfort of running car.
The purpose of this utility model is achieved in that wave uniformsection leaf spring, equipped with grasswort, spring clip, steel
Flat spring and centre bolt, leaf spring are the main body of wave uniformsection leaf spring, and the both ends of the leaf spring can be with
Be respectively equipped with connection grasswort, can also one end be equipped with grasswort one end there is no grasswort, can be with both ends all without grasswort, leaf spring
It is fixed equipped with spring clip, the center of leaf spring is equipped with centre bolt, and the wave uniformsection leaf spring is a kind of arc
Face uses the leaf spring of a variety of curvature, using straight segment structure in the middle part of leaf spring, ensures original installation dimension, mode not
Become, it changes the mentality of designing of original leaf spring, it is made to possess in fixed installation length internal ratio conventional steel plates spring longer
Action length, each of leaf spring is closely affixed, and the length of leaf spring is successively decreased successively from top to bottom；It is usually by 3-
14 leaf spring compositions being overlapped mutually.
The defects of the utility model advantageous effect is, overcomes existing automobile leaf spring is keeping raw steel flat spring
In performance basis, change the planform of original leaf spring, enable in the case where installation length is shorter, gather around in need firm
Degree, the offset frequency so as to be needed, and then improve the ride comfort of running car, abrasion is reduced, increases service life.
Description of the drawings
Fig. 1 is the common plate spring structure schematic diagram of existing cross-section；
Fig. 2 is a kind of structure diagram of the embodiment of the utility model.
Wherein, 1, grasswort；2nd, spring clip；3rd, centre bolt；4th, leaf spring.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Fig. 2, the utility model wave uniformsection leaf spring, equipped with grasswort 1, spring clip 2, centre bolt 3
With leaf spring 4, leaf spring 4 is the main body of wave uniformsection leaf spring, and the both ends of the leaf spring 4 can be distinguished
Equipped with connection grasswort 1, can also one end be equipped with 1 one end of grasswort there is no grasswort 1, can be with both ends all without grasswort 1, leaf spring
4 fix equipped with spring clip 2, and the center of leaf spring 2 is equipped with centre bolt 3, and the wave uniformsection leaf spring is one
Kind of cambered surface uses the leaf spring 4 of a variety of curvature, and straight segment structure is used at 4 middle part of leaf spring, ensure original installation dimension,
Mode is constant, it changes the mentality of designing of original leaf spring 4, makes it in fixed installation length internal ratio conventional steel plates spring 4
Possess longer action length, leaf spring 4 each is closely affixed, and the length of leaf spring 4 is successively decreased successively from top to bottom；
The leaf spring 4 that it is usually overlapped mutually by 3-14 pieces forms.
The leaf spring 4 is the uniformsection leaf spring that a kind of cambered surface uses undaform, and each is closely affixed, and both ends are bent
Rate, piece type are for convenience of processing and fabricating using symmetric form, and the size of R numerical value and quantity can according to the design needs really in Fig. 2
It is fixed.
Following table embodies the advantage of such Novel leaf spring in terms of the design calculating of certain leaf spring：
Requirement offset frequency is 100~130 beats/min when usual lorry leaf spring 4 is cross-section, because installation length is shorter,
4 offset frequency of leaf spring has reached 177 beats/min when routinely leaf spring 4 designs, and riding comfort, ride performance are significantly
It reduces, and uses wave uniformsection leaf spring designing scheme, the constant stretched length of installation length increases, and rigidity reduces, full
It carries offset frequency to greatly reduce, riding comfort, ride performance greatly improve, by upper table it is also seen that the utility model
Material cost is slightly higher.
It the above is only one of implementation example of the utility model, all changes made according to technical solutions of the utility model, institute
The function of generation without departing from technical solutions of the utility model range when, belong to the scope of protection of the utility model.
