Description

Self-cleaning rubber track

Technical Field

The invention belongs to the field of crawler-type traveling systems, and particularly relates to a self-cleaning rubber crawler.

Background

Rubber track traveling system often uses in adverse circumstances such as mire, inevitably has mud bits, sand and soil etc. to be drawn into among the traveling system and form piling up, and these accumulational mud bits or sand and soil etc. can influence the mutual motion of each subassembly among the rubber track traveling system, through the life of the lowering system such as aggravation wearing and tearing, if: hard small debris such as sand and stone can cause abrasion of the meshed part of the driving teeth of the rubber track and the driving wheel, and larger debris can even induce the phenomenon of tooth jumping; debris and the like are accumulated on the inner surface of the crawler belt body and are more difficult to separate after being repeatedly rolled by the loading wheel, so that the tensioning degree of the crawler belt is increased; debris, etc. that adheres to the surface of the road wheels or other components and rubs against rubber track related structures can accelerate wear of these components and tracks. In addition, the accumulation of mud, sand, or the like increases the weight of the rubber crawler travel system, increases the power consumption of the vehicle, and improvement is urgently needed.

Disclosure of Invention

In view of this, the present invention provides a self-cleaning rubber track, which has a protrusion structure distributed on the inner edge thereof, to overcome the defects in the prior art. When the rubber track walking system runs, the edge convex structure can prevent sediment in the terrain and the like from entering the walking system, and meanwhile, the accumulated objects on the components such as the loading wheels and the like can be scraped and thrown out. Through continuously traveling, mud chips entering the rubber crawler traveling system can be continuously reduced, and the self-cleaning function is realized.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

a self-cleaning rubber track comprises a track body and the like, wherein the outer surface of the track body is provided with pattern bulges and the like:

the inner surface of the crawler belt body is provided with a single-row or a plurality of rows of convex structures close to the edge of the crawler belt body, the bottom of each edge convex structure is fixedly connected with the crawler belt body, the tail end extending along each direction of the inner surface of the crawler belt body forms a side surface, each side surface is inwards inclined, so that the shape of each edge convex structure is gradually contracted from the bottom to the top, namely, the other surfaces except the top and the bottom are inwards inclined;

further, the inclination angle of the side surface of the edge convex structure relative to the normal vector of the inner surface of the crawler body is preferably 0-20 degrees, and the normal vector of the inner surface of the crawler body is directed to the inner surface from the outer surface of the crawler body.

Further, the side surface of the edge projection structure near the middle of the track body has a flat surface structure which is substantially parallel to the length direction of the track for guiding the track, called a guide surface.

Further, the edge convex structure has a plane structure on two ends or one end surface in the length direction of the crawler belt, and the plane structure is called as a mud removing surface.

Furthermore, the included angle between the desliming surface and the guide surface is less than or equal to 90 degrees, and the measuring plane of the included angle is perpendicular to the straight line of the desliming surface and the guide surface.

Furthermore, the inner side surface of the rubber track far away from the edge of the track body is provided with a single-row or a plurality of rows of protruding structures, the bottom of each protruding structure is fixedly connected with the track body, the length of each protruding structure is gradually reduced from the bottom to the top along the width direction of the track, and the length of each protruding structure is gradually reduced from the bottom to the top along the length direction of the track, so that the shape of each protruding structure is gradually contracted from the bottom to the top.

Furthermore, the tail end face formed by the inner convex structure extending along the length direction of the crawler is a driving surface which is a continuous smooth curved surface, the driving surface is divided by a normal plane in the width direction of the crawler, the section of the driving surface is a smooth continuous curve, the bottom of the driving surface is in smooth transition with the surface of the crawler through an arc, and the driving surface is used for being meshed with a driving wheel of a rubber crawler traveling system to transmit power.

Further, the inner projection structure extends in the width direction of the track to form a tip end having a flat surface structure substantially parallel to the length direction of the track for guiding the track, which is called a guide surface. A normal plane in the length direction of the crawler belt is used for subdividing the guide surface, the profile of the section of the guide surface mainly comprises straight lines, and the bottoms of the straight lines are in smooth transition with the inner surface of the crawler belt body.

Further, the edge protrusion structures and the inner protrusion structures are arranged at the same intervals in the track length direction.

Furthermore, the surfaces of the edge convex structures, the surfaces of the inner convex structures and the inner surface of the crawler body are in round angle or arc smooth transition.

Compared with the prior art, the invention has the following advantages:

(1) the guide surface and the mud-removing surface of the edge protruding structure form a ridged part in an acute angle form, during driving, the crawler scrapes off the accumulated mud chips on components such as the bogie wheels through the ridged part, and the inclined mud-removing surface facilitates outward discharge of the mud chips, so that accumulation of the mud chips in the traveling system is reduced. When the traveling system skids, the edge convex structure can throw away silt and the like under the sliding action of the crawler belt, and prevent mud chips, sandy soil and the like from entering the traveling system.

(2) The continuous smooth curved surface form of interior protruding structure driving surface can make interior protruding structure have when suitable height and intensity, guarantees drive wheel and track meshing in-process, and the drive round pin on the drive wheel can directly withstand the bottom of interior protruding structure promptly driving surface and the circular arc transition department of track internal surface to get into the engaged state, rather than with the driving surface contact and just withstand the bottom of interior protruding structure after sliding a certain distance, also directly leave from the bottom of interior protruding structure when breaking away from the meshing. The abrasion, the heating and the like caused by the sliding between the driving wheel and the crawler belt in the meshing process are reduced, the service life of related components is prolonged, and the power consumption of the rubber crawler belt walking system is reduced;

in addition, during the traveling of the traveling system, the ridge-shaped part formed by the guide surface and the driving surface of the inner convex structure can further scrape off accumulated mud chips which enter the traveling system on components such as a bogie wheel and the like, and the scraped mud chips can enter the gap of the inner convex structure along the length direction. Mud and the like in the clearance can be extruded and fall off when the crawler belt is engaged with the driving wheel, and part of the mud and the like can fall in the action range of the edge convex structure so as to be discharged.

Through the above effects, the walking system is ensured to prevent mud chips and the like from entering when passing through the bad terrain, and the internal mud chips are gradually discharged when the walking system runs after being separated from the bad terrain, so that self-cleaning is realized.
