Description
Technical field
The present invention relates to a kind of novel structure of rubber belt track, relate in particular to a kind of rubber belt track that on wetland, travels that is mainly used in.
Background technology
In the rubber belt track that is suitable on wetland, travelling, be separated by constant spacing and bury core components underground along the elastomeric length direction of ring-shaped rubber, in the core components outer felt around steel cord, be formed with the plate tooth in the rubber elastomer outside, connect the caoutchouc elasticity inside and outside and be formed with conjugate foramen between core components, it and drive sprocket mesh.
Fig. 8 is interior all side birds-eye vieies of the rubber belt track that always is being extensive use of, and Fig. 9 is the outer circumferential side birds-eye view, and Figure 10 is the cutaway view of cutting open along B-B line among Fig. 8.The 1st, rubber elastomer, continuous up and down along paper in Fig. 8.The 2nd, the core components that the constant spacing of being separated by in rubber elastomer 1 is buried underground, in core components 2, central portion is and drive sprocket ingear junction surface 2a that left and right alar part 2b, 2c are embedded in the rubber elastomer 1.The 3rd, be embedded in the steel cord in this alar part 2b outside.And, on core gold 2, also have interior side-prominent a pair of projection 2d towards rubber elastomer 1.4a, 4b are the plate teeth, and they are linearly, are positioned at the outer circumferential side of rubber elastomer 1, and long and short plate tooth 4a, 4b alternate configurations.The 5th, with drive sprocket ingear conjugate foramen, it is formed between central portion 2a, the 2a of core components 2,2 of adjacency, is the inside and outside surperficial shape that connects rubber elastomer 1.
Yet the rubber belt track of this prior art but has its shortcoming---the operator is caused vibration and brings walk the conjugate foramen 5 into from the ground.The former is owing to be on the position on plate tooth 4a, the 4b and the locational situation that is between them alternately takes place at the runner 10 that the inner peripheral surface of rubber belt track rolls, promptly, because of the situation that is positioned at the situation on plate tooth 4a, the 4b and leaves from it alternately takes place, so supporting and non-supporting situation for ground plane also alternately take place, therefore cause runner play about in the of 10, vibration is taken place inevitably.
In addition, be driven sprocket 20 and compress and solidify, become the walk shape and outwards under the clan, so this walk can be fallen on other objects sometimes, this is bad phenomenon owing to being attached near the conjugate foramen 5 mud.
Summary of the invention
The present invention makes in view of the various situations in the above prior art use, and its main purpose is, a kind of rubber belt track is provided, and it comprises: the ring-shaped rubber elastic body; Core components, it is separated by constant spacing and buries underground along the elastomeric length direction of ring-shaped rubber; Steel cord, it from this core components outside to its winding; The junction surface, it is formed between the core components, engages with drive sprocket; The plate tooth is formed on the elastomeric outer peripheral face of ring-shaped rubber, and wherein, the junction surface that engages with drive sprocket is for there being end recess.
And, in this rubber belt track, this plate tooth is preferably formed as the outside that end recess is arranged in this, particularly, this plate tooth is with respect to the Width tilted configuration of rubber elastomer, in addition, one side of something from about the Width of rubber elastomer may extend into the long slab tooth of Width end and the short slab tooth alternate configurations midway that only extends to above-mentioned Width.
Maximum of the present invention is characterised in that the junction surface that engages with drive sprocket is for there being end recess.In the rubber belt track of prior art, the junction surface that engages with drive sprocket must be the structure that connects surfaces externally and internally.Therefore, have mud by this conjugate foramen to be spherical and be rejected to the outside, and this mud is fallen the problem points on the contiguous object.Yet use the present invention but can avoid the generation of the effluent of this walk shape.Expect also that in addition mud etc. can accumulate in the end recess, but consider that this rubber belt track mainly travels at wetland, the mud that enters this recess all is rich in moisture, so can not solidify in this recess, is very suitable for practicality.
Like this, the another feature that the junction surface is designed to end recess is that the plate tooth that is formed at the outer circumferential side of rubber elastomer can dispose arbitrarily.That is, in the rubber belt track of prior art, because the conjugate foramen that certainly exists separated by a certain interval, so the configuration degree of freedom of this plate tooth is lower, yet because the present invention does not have conjugate foramen, so the configuration degree of freedom of plate tooth is high.Therefore, for example no matter prevent vibration for seeking, or desire increases propulsive force, can select with these is the plate tooth of purpose.
In addition, since the junction surface that engages with drive sprocket for end recess is arranged, so this has the rubber thickness of end recess not too thick.Therefore, can make rubber elastomer slightly thicker corresponding to the position of this recess.About this point, preferably the plate tooth is set corresponding to the position that end recess is arranged.
About this plate tooth, for reducing generation of vibration, best Width tilted configuration plate tooth with respect to rubber elastomer; In addition, for increasing propulsive force the mud of rubber belt track outside face is fallen, therefore, one side of something from about the Width of rubber elastomer preferably may extend into the plate tooth (long slab tooth) of Width end and plate tooth midway (short slab tooth) alternate configurations that only extends to above-mentioned Width.
By making the plate tooth become the former such structure, when the runner as vibrative reason travels, this runner perseverance is on the plate tooth, so avoided the play up and down of runner, thereby prevented generation of vibration, on the other hand, become the such structure of the latter by making the plate tooth, can impel a part of peeling off, fall in the mud that is sandwiched in the plate between cog, thereby improve propulsive force.
