Abstract

A core iron for rubber track comprising an anti-wearing layer, a positioning guiding angle, a bead, and an adhesion-increasing groove is provided. A guiding rail surface takes on a parallelogram allocated in the way of upper and lower opposition. The vertical projections of the neighboring iron rail surface sharp angle top overlaps, thus overcoming shortcomings such as axial swaying of the supporting wheel and hence incurred big shock and noise. Meanwhile, the product also makes the bending semi-diameter of the track much smaller to render concise structure of the machine.

Description

Rubber belt track is with new core iron

Affiliated technical field

The utility model belongs to self-propelled vehicle, trailer group in International Patent Classification (IPC), i.e. B62D, particularly core for rubber track, i.e. B62D55/20.

Background technology

At present both at home and abroad core for rubber track is made by metal forging or casting, be to satisfy drive, with the bonding and guide rail effect of steel curtain.When high-power transmission, very easily string is moving between traditional core iron, and guide pass and drive surface be than quick-wearing, thereby has changed meshing performance.The tradition core iron also easily breaks away from the steel curtain, makes the power transmission inefficacy of crawler belt, and the flexural deformation of bottom wing on the core iron.

No. 200520115985.9 patent application technology of our company have overcome above-mentioned shortcoming substantially.But owing between the adjacent core iron guide pass bigger gap is arranged, so caterpillar wheel is absorbed in this gap and axial wobble easily.

The utility model content

The purpose of this utility model provides a kind of rubber belt track with new core iron.

It can not only be avoided, and string moves between core iron, has prolonged the life-span, is more suitable for the rubber belt track of high-power transmission, and can avoids the axial wobble of caterpillar wheel.

It is as follows to disclose new technical scheme:

A kind of rubber belt track is with new core iron, there is prominent muscle in the front of both wing portions up and down, there is the tackify groove at the back side, there is upper and lower guide rail in front between itself and the central part, there is laterally zygomorphic positioning and guiding angle at the back side between alar part and the central part up and down, the drive surface of said guide pass up and down and central part has wearing course, said guide pass parallelogram, the parallelogram reversed arrangement of guide pass up and down; Gap center-point between gap center-point between last adjacent rails face and following adjacent rails face is not on same vertical line; The vertical direction projection on the acute angle summit of left and right sides adjacent rails face is superimposed mutually.

On probation according to the sample warp that this scheme is made, not only can be fit to the requirement of high-power transmission, be absorbed in the guide pass gap and the drawback of axial wobble and overcome caterpillar wheel, thereby machine run balance, noise is little, and is not easy to wear, prolonged the life-span greatlyyer, can also satisfy the more requirement of small-bend radius of crawler belt, make more compact structure.

The specific embodiment

A kind of rubber belt track is with new core iron 1, there is prominent muscle 2 in the front of both wing portions up and down, there is the tackify groove at the back side, there is upper and lower guide rail in front between itself and the central part, there is laterally zygomorphic positioning and guiding angle at the back side between alar part and the central part up and down, and the drive surface of said guide pass 4 up and down and central part has wearing course, said guide pass 4 parallelograms, the parallelogram reversed arrangement of guide pass 4 is promptly rotated coincidence up and down; The gap center-point that gap center-point that last adjacent core iron guide pass is 4 and following adjacent core iron guide pass are 4 is not on same vertical line; The vertical direction projection on the acute angle summit of left and right sides adjacent rails face 4 is superimposed mutually.Caterpillar wheel 3 steadily rolls on guide pass 4 all the time like this, has overcome the drawback that machine vibration is big, noise is big of axially waving and bringing that is absorbed in the gap.

Claims

A kind of rubber belt track is with new core iron (1), there is prominent muscle (2) in the front of both wing portions up and down, there is the tackify groove at the back side, there is upper and lower guide rail in front between itself and the central part, there is laterally zygomorphic positioning and guiding angle at the back side between alar part and the central part up and down, the drive surface of said guide pass (4) up and down and central part has wearing course, it is characterized in that: said guide pass (4) parallelogram, the parallelogram reversed arrangement of guide pass (4) up and down; Gap center-point between gap center-point between last adjacent rails face (4) and following adjacent rails face (4) is not on same vertical line; The vertical direction projection on the acute angle summit of left and right sides adjacent rails face (4) is superimposed mutually.
