Abstract
The utility model discloses an inner structure of a rubber belt track which is used for the agricultural mechanism, the construction machinery and the machine running on the snow, a metal piece (5) is arranged in the middle of a rubber body (1); two side wins of the metal piece are each provided with a group of curtains (2); the lower parts of the two side wings are each provided with a group of middle curtains (3) and a group of lower curtains (4); a steel cord (6) is positioned between the middle curtains (3) and the lower curtain (4). In such a way, the metal piece (5) is positioned under the state that the metal piece (5) is firmly clamped by each curtain. The curtains can obviously enhance the tensile strength of the rubber belt track, reduce the transverse crack and extend the service life.
Description
The utility model relates to a kind of inner structure of road machine running gear, especially by rubber bodies, in bury the inner structure that metal piece and steel cord are formed rubber belt track.
Rubber belt track is widely used in the running device of field machine, vehicle for construction and snowfield machinery.It integrates the advantage of iron and steel crawler belt and rubber tire, thereby development is very fast.Modal rubber belt track inner structure has two kinds on market at present.Bury metal piece between a kind of rubber belt track inner structure is placed in one by rubber bodies and two flanks and form, but this structural metal part is firm inadequately with combining of rubber bodies, endwise tensile strength is relatively poor, and the cross break that rubber covers band takes place easily.The another kind of rubber that rubber plant's production is consolidated in Hangzhou forever covers band, be on the said structure basis, sodium buries metal piece two flank lower planes, every side is all set up one and is arranged in a row bundle finer wire cord, improved endwise tensile strength to a certain extent, but be subjected to mechanical running device drive wheel in bury metal piece and rubber bodies to combine firmness still not ideal enough, cross break makes the problem that the rubber belt track life-span reduces, also still exist, generally have only in 500 hours service life.
The purpose of this utility model provides the rubber belt track endwise tensile strength is increased, in bury metal piece and combine with rubber bodies firmly, whole rubber covers is with the rubber that prolongs more than one times service life to cover the band inner structure.
For achieving the above object, rubber belt track inner structure of the present utility model is made up of rubber bodies, metal piece, steel cord, metal piece and steel cord all place in the rubber bodies, it is characterized in that: rubber bodies inner with the metal piece flank on the plane parallel cord 1-5 layer on a group that is symmetrically arranged, evenly equidistant isometric distribution between layer and the layer, orlop is apart from the minimum 3mm of metal piece; Respectively arrange the middle cord and the following cord of one group of 1-2 layer up and down with metal piece flank lower plane parallel steel wire cord in rubber bodies inside, middle cord is identical with following curtain cloth layer, wherein, the middle cord the superiors and metal piece minor increment are 3mm, the middle cord orlop and the following cord the superiors are 3mm apart from the steel cord minimum, and left-right symmetric.
After adopting such structure, owing to all have the multilayer carcass plies to seize on both sides by the arms in interior top and bottom of burying metal piece two flanks, the bonding properties of burying metal piece and rubber bodies in making is greatly improved; And the setting of multilayer carcass plies has also increased endwise tensile strength and the ability of bearing load significantly in the rubber bodies, reduces the possibility of cross break, has prolonged the service life of rubber belt track.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the sectional elevation of the rubber belt track inner structure specific embodiment of the present utility model.
Rubber belt track inner structure shown in Figure 1 is made up of rubber bodies 1, last cord 2, steel cord 6, metal piece 5, middle cord 3 and following cord 4.Be embedded in the metal piece 5 in the middle of the rubber bodies made from antifriction rubber 1; Last cord 2 can have the 1-5 layer, with plane parallel on metal piece 5 flanks, and even equidistant isometric distribution between layer and the layer, orlop cord plane on metal piece 5 flanks is not less than 3MM; Middle cord 3, cord 4 and parallel with lower plane under steel cord 6 all is positioned at metal piece 5 flank lower planes down, and steel cord 6 is between middle cord 3 and following cord 4, middle cord 3 and following cord 4 keep equidistant with steel cord 6, middle cord 3 should be identical with following cord 4 numbers of plies, can be the 1-2 layer, middle cord 3 be not less than 3MM apart from metal piece 5 flank lower planes.
Certainly, the structure of this carcass plies and distribution can also be adopted other modes, as above plane parallel on cord 2 and the rubber bodies 1; Middle cord 3 and following cord 4 fuse steel cord 6 are wrapped in the centre; Cord 3 or following cord 4 in the middle of the cancellation.These conversion all drop within the protection domain of the present utility model.
Claims (3)
1, a kind of rubber belt track inner structure, form by rubber bodies, metal piece, steel cord, metal piece and steel cord all place in the rubber bodies, it is characterized in that: rubber bodies (1) inner with metal piece (5) flank on the plane parallel cord (2) on a group that is symmetrically arranged; Respectively arrange one group of middle cord (3) and following cord (4) in rubber bodies (1) inside up and down with metal piece (5) flank lower plane parallel steel wire cord (6), and left-right symmetric.
2, rubber belt track inner structure according to claim 1 is characterized in that: going up cord (2) can have the 1-5 layer, evenly equidistant isometric distribution between layer and the layer, orlop cord plane minimum 3mm on metal piece (5) flank.
3, rubber belt track inner structure according to claim 1, it is characterized in that: middle cord (3) and following cord (4) can be the 1-2 layers, middle cord (3) is identical with following cord (4) number of plies, and each layer is wide, wherein, middle curtain city (3) the superiors and metal piece (5) minor increment are 3mm, and middle cord (3) orlop and following cord (4) the superiors are 3mm apart from steel cord (6) minimum.
