Series connection conical rubber spring on rubber metal pad in this utility model, rubber metal pad is horizontally disposed with, and conical rubber spring is vertical
Arranging, wherein little the and horizontal and vertical rigidity of the vertical stiffness of conical rubber spring is relatively big, and rubber metal pad vertical stiffness is big and horizontal
Less with longitudinal rigidity, conical rubber spring is connected on rubber metal pad, according to stiffness at the end computing formula KSystem＜ min
KVolute spring, KRubber metal pad, it is known that the vertical stiffness of train is mainly determined by the vertical stiffness of conical rubber spring, horizontal and vertical
Rigidity is mainly determined by the horizontal and vertical rigidity of rubber metal pad, and therefore this utility model is by rubber metal pad and conical rubber spring
Series connection, it is thus achieved that less vertical stiffness, Longitudinal stiffness and transverse stiffness, thus bigger vertical and lateral displacement can be provided, full
Foot low floor vehicle actual motion demand；Adjust conical rubber spring vertical stiffness i.e. adjust of the present utility model vertical just
Degree, the vertical and horizontal rigidity adjusting rubber metal pad i.e. adjusts vertical and horizontal rigidity of the present utility model, makes vertical, horizontal and vertical
Easily mate to rigidity.This utility model simple in construction, takes up room little, and the requirement to installing space is low, can fully meet lowly
Wooden handcart two is the restricted requirement of spring suspension device setting height(from bottom).
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
By drawings and Examples, this utility model will be further described below.
As it is shown in figure 1, two is spring suspension device, including rubber metal pad 1, cone rubber bullet that described rubber metal pad 1 is connected
Spring 2, described rubber metal pad 1 is horizontally disposed with, and described conical rubber spring 2 is vertically installed in the top of rubber metal pad 1.
Described rubber metal pad 1 is vulcanized by top board 11, dividing plate 12, base plate 13 and rubber layer 14 and is formed, described cone rubber
Spring 2 is vulcanized by mandrel 21, dividing plate 22, overcoat 23 and rubber 24 and is formed, and described mandrel 21 is opened step vertically and leads to
Hole 21.1, described top board 11 has the female thread mounting cylinder 11.1 corresponding with step through hole 21.1, and mandrel 21 is placed in
On top board 11, in the stepped through hole of female thread mounting cylinder 11.1 insert stand 21.1, bolt 3 is fastened in female thread mounting cylinder 11.1 will
Described mandrel 21 is fixed on top board 11.
Having shop bolt 11.2 on described top board 11, the bottom surface of described mandrel 21 has joins with shop bolt 11.2
The pin-and-hole closed, mandrel 21 is placed on top board 11, and described shop bolt 11.2 inserts in described pin-and-hole.Described shop bolt
11.2 is multiple along the excircle direction uniform intervals distribution of female thread mounting cylinder 11.1.Described rubber metal pad 1 is cuboid rubber
Heap.
Above-described two is spring suspension device, rubber metal pad 1 and conical rubber spring 2 individually sulfidization molding, then
Conical rubber spring 2 is fixed on the top of rubber metal pad 1 by bolt 3, and the shop bolt 11.2 on top board 11 inserts mandrel 21
In the pin-and-hole of bottom surface, play and prevent rubber metal pad 1 and conical rubber spring 2 from acting in relative rotation.Wherein conical rubber spring 2
Vertical stiffness is little, and typically between the kN/mm of 0.6kN/mm ~ 1, and horizontal and vertical rigidity is big, typically at .5kN/mm ~ 6.5kN/
Between mm, the vertical stiffness of rubber metal pad 1 is big, generally higher than 10kN/mm, and horizontal and vertical rigidity is little, generally less than 0.8kN/
Mm, according to stiffness at the end computing formula KSystem＜ min { KVolute spring, KRubber metal pad, it is known that above-described two is hanging down of spring suspension device
Straight rigidity is mainly determined by the vertical stiffness of conical rubber spring, horizontal and vertical rigidity mainly horizontal and vertical by rubber metal pad
Rigidity determines, therefore can come real by the horizontal and vertical rigidity of the vertical stiffness of adjustment conical rubber spring and rubber metal pad
Above-described two is the three-way rigidity coupling of spring suspension device, and wherein the rubber metal pad 2 of rectangular shape can be real different
Longitudinal stiffness and transverse stiffness so that above-described two be elastic suspended device three-way rigidity coupling simpler.
Described two are conical rubber spring 2 of connecting on rubber metal pad 1 in spring suspension device, and rubber metal pad 1 is horizontally disposed with, cone
Shape rubber spring 2 is vertically arranged, and wherein little the and horizontal and vertical rigidity of the vertical stiffness of conical rubber spring 2 is relatively big, rubber metal pad 1
Big and the horizontal and vertical rigidity of vertical stiffness is less, is connected on rubber metal pad 1 by conical rubber spring 2, according to stiffness at the end meter
Calculate formula KSystem＜ min { KVolute spring, KRubber metal pad, it is known that the vertical stiffness of train is mainly by the vertical stiffness of conical rubber spring
Determining, horizontal and vertical rigidity is mainly determined by the horizontal and vertical rigidity of rubber metal pad, and the most above-described two is elastic suspended
Hang device is connected by rubber metal pad 1 and conical rubber spring 2, it is thus achieved that less vertical stiffness, Longitudinal stiffness and transverse stiffness,
Thus bigger vertical and lateral displacement can be provided, meet low floor vehicle actual motion demand；Adjust conical rubber spring 2
Vertical stiffness i.e. adjusts the vertical stiffness that described two are spring suspension device, adjusts the vertical and horizontal rigidity of rubber metal pad 1 i.e.
Described in adjustment two are the vertical and horizontal rigidity of spring suspension device, make rigidity vertical, horizontal and vertical easily mate.Described
Two is spring suspension device simple in construction, takes up room little, and the requirement to installing space is low, can fully meet low floor vehicle two and be
The restricted requirement of spring suspension device setting height(from bottom).
Above in association with accompanying drawing, the technical scheme of this utility model embodiment is completely described, it should be noted that and retouched
The embodiment stated is only a part of embodiment of this utility model, makes based on the embodiment in this utility model, and this area is common
