The track is formed by the combination of multiple track shoes to drive engineering vehicles to move in complex and harsh terrains such as tidal flats, swamps, deserts, fields, ice and snow, gravel, etc. It has good flexibility, is easy to maintain and replace, and can provide better driving force. It is often used in engineering machinery such as excavators, bulldozers, crawler cranes, and pavers.
[0003] For example, the patent number is CN207257819U, and the patent name is: Single-pin type all-rubber segmented combined crawler, which discloses a single-pin type all-rubber segmented combined crawler, including more than two units and a crawler pin, and the two units are connected to each other through the crawler pin to form an annular complex, forming an annular rubber crawler. When the rubber crawler has local core metal or rubber teeth damage or the belt body is broken, the unit body where the corresponding damaged part is located can be replaced, and the entire crawler will not be scrapped due to local damage, which reduces the production and use costs, extends the service life of the rubber crawler, and the unit body is small in size and light in weight, which is convenient for replacement, packaging, transportation and storage.
[0004] The rubber tracks in the prior art are all driven by the inner metal track shoes. However, after the track shoes in the prior art are assembled, there is a large installation gap at the connection of two adjacent track shoes. When the wheel surface of the supporting wheel passes through the gap at the connection of two adjacent track shoes, the wheel surface loses support and rotates unevenly, which generates a large noise. Utility Model Content
[0005] The utility model aims at the deficiencies in the prior art and provides a noise-reducing crawler, which can not only reduce noise but also reduce the wear of the outer rubber crawler.
[0006] In order to solve the above technical problems, the utility model solves the problems through the following technical solutions: a noise-reducing crawler, comprising a plurality of track shoes that cooperate with each other, the track shoes comprising a plate body formed by two plate members connected by a connecting rod, and a front connecting lug and a rear connecting lug are integrally arranged at both ends of the plate members. When two adjacent track shoes are combined, the rear connecting lug of the front track shoe cooperates with the front connecting lug of the rear track shoe, so that only a rotation gap is reserved between the front working surface of the front connecting lug of the rear track shoe and the rear end portion of the plate body of the front track shoe, and only a rotation gap is reserved between the side end surface of the front connecting lug of the rear track shoe and the inner working surface of the rear connecting lug of the front track shoe, so that the wheel surface of the supporting wheel always rotates on the supporting surface, avoiding noise caused by uneven rotation.

[0008] In the above technical solution, the tread width L1 on the first plate member and the second plate member are both set to 0-23 mm, which is conducive to the wheel surface of the supporting wheel always rotating on the supporting surface.
[0009] In the above technical solution, intermediate anti-slip baffles are respectively provided on the inner working surfaces of the first plate member and the second plate member and close to the edge of the connecting rod and protrude in the height direction to prevent the chain plate from slipping out of the middle of the supporting wheel.
[0010] In the above technical solution, the width L2 from the outer working surface of the middle anti-slip baffle away from the connecting rod to the outermost end of the front connecting lug is 0 to 40 mm.
[0011] In the above technical solution, the intermediate anti-slip baffle is a first intermediate anti-slip baffle arranged on the first plate and a second intermediate anti-slip baffle arranged on the second plate, and the first intermediate anti-slip baffle and the second intermediate anti-slip baffle are symmetrically arranged. The arrangement of the intermediate anti-slip baffle is beneficial to preventing the chain plate from falling out from the middle of the supporting wheel.
[0012] In the above technical solution, a first front connecting lug and a first rear connecting lug are respectively provided at both ends along the assembly direction of the first plate.

[0015] In the above technical solution, anti-slip protrusions are arranged on the outer working surfaces corresponding to the first front connecting lug, the first rear connecting lug, the second front connecting lug and the second rear connecting lug.
[0016] Compared with the prior art, the utility model has the following beneficial effects: by reserving only a rotation gap between the working surfaces of the mating parts of two adjacent track shoes, the wheel surface of the supporting wheel always rotates on the supporting surface, thereby avoiding the noise caused by uneven rotation; at the same time, an intermediate anti-slip baffle is provided on the plate, which is beneficial to prevent the chain plate from escaping from the middle of the supporting wheel; anti-slip protrusions are provided on the outer working surfaces of the front connecting lug and the rear connecting lug, and the height of the anti-slip protrusion is reduced, which is beneficial to reduce the wear on the rubber crawler track and extend the service life; the weight of the track shoe can be reduced, which is beneficial to the lightweight of the product.

[0027] See also Figures 1 to 5 A noise reduction crawler comprises a plurality of crawler plates 1 which cooperate with each other at the head and tail ends, and a front connecting lug and a rear connecting lug are integrally arranged at both ends of the plate. When two adjacent crawler plates 1 are combined, the rear connecting lug of the front crawler plate cooperates with the front connecting lug of the rear crawler plate, so that only a rotation gap is reserved between the front working surface of the front connecting lug of the rear crawler plate and the rear end portion of the plate body of the front crawler plate, and only a rotation gap is reserved between the side end surface of the front connecting lug of the rear crawler plate and the inner working surface of the rear connecting lug of the front crawler plate.
[0028] The specific structure of the track shoe 1 includes a first plate member 12, a second plate member 13 and a connecting rod 11. The first plate member 12 and the second plate member 13 are integrally connected to form an integral plate body through the connecting rod 11.
[0029] Among them, the first front connecting lug 122a and the first rear connecting lug 122b are respectively provided at the two ends along the assembly direction of the first plate 12, that is, the front end of the first plate 12 and the rear end of the first plate 12. The first front connecting lug 122a and the first rear connecting lug 122b are both provided with a pin shaft hole for installing a pin shaft; the first rear connecting lug 122b is a double lug structure, so that the double lug structure of the first front connecting lug 122a and the first rear connecting lug 122b forms a herringbone arrangement. And the first intermediate anti-slip baffle 121 is protruding in the height direction on the inner working surface of the first plate 12 located between the first rear connecting lug 122b and the first rear connecting lug 122b and close to the side of the connecting rod 11, that is, the inner working surface close to the edge of the connecting rod.
[0030] A first anti-slip protrusion 122c is arranged on the outer working surface corresponding to the first front connecting lug 122a and the first rear connecting lug 122b. The height of the first anti-slip protrusion 122c is set to be lowered to only meet the anti-slip effect. The lowered first anti-slip protrusion 122c can help reduce the wear of the rubber track and increase its service life. At the same time, the height is set lower, which reduces the overall mass of the plate and is conducive to lightweight equipment.
[0031] A second front connecting lug 132a and a second rear connecting lug 132b are respectively provided at the two ends along the assembly direction of the second plate 13, i.e., the front end of the second plate 13 and the rear end of the second plate 13. The second front connecting lug 132a and the second rear connecting lug 132b are both provided with a pin shaft hole for installing a pin shaft; the second rear connecting lug 132b is a double lug structure, and the double lug structure of the second front connecting lug 132a and the second rear connecting lug 132b forms a herringbone arrangement. A second intermediate anti-slip baffle 131 is provided protrudingly in the height direction on the inner working surface of the second plate 13 located between the second front connecting lug 132a and the second rear connecting lug 132b and close to one side of the connecting rod 11, i.e., on the inner working surface close to the edge of the connecting rod, and is symmetrically arranged with the first intermediate anti-slip baffle 121. The setting of the intermediate anti-slip baffle is conducive to preventing the chain plate from slipping out of the middle of the supporting wheel.
[0032] A second anti-slip protrusion 132c is arranged on the outer working surface corresponding to the second front connecting lug 132a and the second rear connecting lug 132b. The height of the second anti-slip protrusion 132c is set to be lowered to only meet the anti-slip effect. The lowered second anti-slip protrusion 132c can help reduce the wear of the rubber track and increase its service life. At the same time, the height is set lower, which reduces the overall mass of the plate and is conducive to lightweighting of the equipment.
[0033] See also Figure 2 Taking two adjacent track shoes A and B as an example, when the track shoe A is combined with the track shoe B, the first rear connecting lug 122b of the track shoe A cooperates with the first front connecting lug 122a of the track shoe B, and the connection is achieved by installing a pin shaft penetrating into the pin shaft hole, so that only a rotation gap is reserved between the front end of the second front connecting lug 132a of the track shoe B and the rear end of the first plate member 12 of the track shoe A, and the rear end of the first plate member 12 is the end face of the first plate member 12 between the double-ear structure of the first rear connecting lug 122b; and only a rotation gap is reserved between one of the lugs of the first rear connecting lug 122b of the track shoe A close to the connecting rod 11 and the cooperating working surface of the first front connecting lug 122a of the track shoe B, which can ensure the working performance while always ensuring that the wheel surface of the supporting wheel always rotates on the supporting surface, avoiding the noise caused by uneven rotation.
[0034] Correspondingly, the matching relationship between the second rear connecting lug 132b of the A track shoe and the second front connecting lug 132a of the B track shoe is consistent with the matching relationship between the first rear connecting lug 122b and the first front connecting lug 122a of the B track shoe.
[0035] See also Figure 4In order to achieve higher processing consistency, the tread width L1 on the first plate 12 and the second plate 13 are both set to 0-23 mm. Of course, within this value range, at the extreme level, the tread width L1 can be made 0, then, correspondingly, the width of the first front connecting lug 122a can be increased accordingly. Obviously, this value range depends on the width design of the first front connecting lug 122a in order to achieve the best matching relationship.
[0036] Of course, in order to improve the fault tolerance rate, the width L2 from the outer working surface of the first middle anti-slip baffle 121 and the second middle anti-slip baffle 131 away from the connecting rod side to the outermost end of the front connecting lug can also be controlled to be 0 to 40 mm.
[0037] In this way, it can be ensured that the wheel surface of the supporting wheel always rotates on the supporting surface, avoiding the noise caused by uneven rotation.
[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
