阅读说明：本技术 全地形履带及带轮组合机构 (All-terrain crawler belt and belt wheel combined mechanism ) 是由 李少麟 于 2019-11-01 设计创作，主要内容包括：本发明提供一种全地形履带及带轮组合机构,包括带轮和套设于带轮外侧的履带,履带包括外履带面和内履带面,外履带面上间隔设置有向外突出的履带外齿,履带外齿之间的外履带面形成外履带凹面,内履带面上设置有向外突出的履带内齿；带轮外侧与履带接触处对应履带内齿的位置设置有向内凹陷的带轮凹齿,带轮凹齿的结构与履带内齿的结构相配合；带轮凹齿为贯穿的通孔,带轮凹齿朝向履带的一侧和朝向带轮内部的一侧均为通透性的。解决了现有的履带行走机构无法适应各种路面结构,履带带动力差的问题,通过履带内齿与通透性的带轮凹齿配合,为履带提供足够的带动力的同时,还能通过带轮凹齿将夹杂在内履带的沙石等杂物排出。(The invention provides an all-terrain crawler belt and a belt wheel combined mechanism, which comprise a belt wheel and a crawler belt sleeved outside the belt wheel, wherein the crawler belt comprises an outer crawler belt surface and an inner crawler belt surface, outer crawler belt teeth protruding outwards are arranged on the outer crawler belt surface at intervals, an outer crawler belt surface between the outer crawler belt teeth forms an outer crawler belt concave surface, and inner crawler belt teeth protruding outwards are arranged on the inner crawler belt surface; the contact part of the outer side of the belt wheel and the crawler belt is provided with belt wheel concave teeth which are sunken inwards at the positions corresponding to the inner teeth of the crawler belt, and the structures of the belt wheel concave teeth are matched with the structures of the inner teeth of the crawler belt; the concave tooth of band pulley is the through-hole that runs through, and the concave tooth of band pulley is the permeability towards one side of track and towards the inside one side of band pulley. The problem of current track running gear can't adapt to various road surface structures, track area power is poor is solved, through the cooperation of the concave tooth of band pulley of track internal tooth and permeability, for the track provide sufficient area power in, can also discharge debris such as gravel and sand of track including being mingled with through the concave tooth of band pulley.)

1. An all-terrain crawler belt and belt wheel combined mechanism is characterized by comprising,

the belt wheel is sleeved on the crawler belt on the outer side of the belt wheel;

the crawler belt comprises an outer crawler belt surface and an inner crawler belt surface, the outer crawler belt surface is used for being in contact with a walking road surface, the inner crawler belt surface is used for being in contact with a belt wheel, outer crawler belt teeth protruding outwards are arranged on the outer crawler belt surface at intervals, an outer crawler belt concave surface is formed on the outer crawler belt surface between the outer crawler belt teeth, and inner crawler belt teeth protruding outwards are arranged on the inner crawler belt surface;

the contact part of the outer side of the belt wheel and the crawler belt is provided with belt wheel concave teeth which are sunken inwards corresponding to the inner teeth of the crawler belt, and the structure of the belt wheel concave teeth is matched with that of the inner teeth of the crawler belt; the concave tooth of band pulley is the through-hole that runs through, and the concave tooth of band pulley is the permeability towards one side of track and towards the inside one side of band pulley.

2. An all-terrain track and pulley combination as claimed in claim 1, wherein the base area of the contact surface of the inner teeth of the track with the inner track surface is greater than the top area of the surface of the inner teeth of the track facing the pulley, and the length and width of the contact surface of the inner teeth of the track with the inner track surface are less than the width of the track.

3. An all terrain track and pulley combination as claimed in claim 2 wherein the track lugs are of convex truncated pyramidal or semi-circular or inverted triangular configuration and the pulley lugs are of inwardly concave configuration to engage the track lugs.

4. An all terrain track and pulley combination as claimed in claim 1 wherein the outside of the pulley is provided with a shield for preventing the track from falling off the outside of the track.

5. An all terrain track and pulley combination as claimed in claim 4 wherein the shield is spaced on either side of the outer side of the pulley, the shield engaging the outer side of the track when assembled and being in one-to-one correspondence with the position of the outer teeth on the track.

6. An all-terrain track and pulley combination as claimed in claim 4, wherein the blocking structure comprises a plate-like rib, the rib is vertically disposed on the outside of the pulley, the rib and the pulley are integrated into a single structure, and the rib is symmetrically disposed on both sides of the track.

7. An all-terrain track and pulley combination as claimed in claim 1, wherein the track inner teeth are disposed at corresponding positions on the outer track concave surface or at corresponding positions on the outer track outer teeth, i.e. the central axis of the track inner teeth corresponds to the central axis of the outer track concave surface, or the central axis of the track inner teeth corresponds to the central axis of the track outer teeth.

8. An all terrain track and pulley combination as defined in claim 1 wherein the outer surfaces of the outer teeth of the track and the concave surface of the outer track are provided with a raised texture.

9. An all terrain track and pulley combination as claimed in claim 8, wherein the texturing is one or more of W-shaped, cross-striped, and twill.

10. A wheelchair comprising a body portion and a chassis comprising an all terrain track and pulley combination as claimed in any one of claims 1 to 9.
