Portion, the secondary recess portion and main recess of at least one subplate spring of every one end are incorgruous, between the mainboard spring and the subplate spring of the first order,
There is the enhancing joint of integrally connected between two subplate springs of arbitrary neighborhood；Several enhancing joints are connected with grasswort.
Preferably, the mainboard spring and secondary plate spring shape are elliptic arc, the elliptic arc of the mainboard spring or subplate spring
Angle account for belonging to elliptical 1/6 ~ 1/3, the series of the subplate spring is 2 ~ 4, and along mainboard spring end toward outside direction subplate spring
Length successively decrease step by step.Mainboard spring or subplate spring are elliptic arc and account for that its 1/3 ~ 1/6 amount of deflection is suitable, rigidity is suitable；Subplate spring
Series should not be excessive, not so may easily cause unstability, and 2 ~ 4 grades are that economic suitable quantity is chosen.
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 subplate spring reduces 12 ~ 27% relative to the subplate spring length of mainboard spring or upper level.Become step by step
For short subplate spring in order to realize the needs of process matching, the optimization design carried out in length is extremely necessary.
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 that are incorgruous and being intended to some curved surface can be carried simultaneously, and play the role of Joint vibration reduction, extend the suitable of leaf spring
Use range.
