Description

Detachable landing rubber block for tracked vehicle

Technical Field

The invention is mainly applied to a tracked vehicle action system, and particularly relates to a detachable landing rubber block of a tracked vehicle.

Background

At present, a metal track is generally adopted as a track of a vehicle for daily training, and a rubberized track is mainly applied to vehicle business exhibitions and national day reading. To the demand of foreign trade tank to full-time kiss-coating track, put forward higher requirement to the track rubber block performance that lands, the main technology attack key point of the rubber block that lands turns into to inside temperature rise control by the wearability, comprehensive performance such as resistant tearing, cutting reaches the target that promotes rubber block life that lands.

Disclosure of Invention

The invention aims to provide a detachable landing rubber block of a tracked vehicle, which has reliable performance, convenient detachment, longer service life, temperature rise control and improved tearing resistance and cutting performance.

The technical scheme of the invention is that the detachable landing rubber block of the tracked vehicle comprises a bottom plate 4, a rubber block 5 and a bolt 6; the bottom plate 4 is of a bowl-shaped structure, a plurality of through holes 7 are formed in the bottom of the bowl shape, the rubber block 5 is vulcanized to two sides of the bottom plate 4, namely one part of the rubber block 5 is located outside the bottom of the bowl, the other part of the rubber block 5 is located inside the bowl, and the two parts are connected through the through holes 7; 2 bolts 6 penetrate through the bottom of the bottom plate 4, and the outer leakage threads of the bolts 6 are connected with the track shoe 2.

The crawler belt has the beneficial effects that the landing rubber blocks are connected with the crawler belt plate to form the whole crawler belt, when a certain landing rubber block is damaged or the service life of the landing rubber block is prolonged, the landing rubber block can be quickly disassembled, the maintenance convenience of the crawler belt is improved, and meanwhile, the crawler belt is protected; the invention is a vulcanization molding integrated structure; according to the invention, the bottom plate adopts a structure with a transverse section in a bowl shape, and coats the lower layer rubber block, so that the uniform stress of the rubber block on the ground is ensured, and the stress concentration is avoided. The bolt is pressed and assembled with the bottom plate in an interference fit mode through a stamping mode, the outer thread leaking part on the bottom plate is used for being connected with the track shoe, the upper layer and the lower layer of the rubber block are combined into a whole through the holes in the vulcanization process through the through holes on the bottom plate, the dual composite strength is realized, the upper layer of the rubber block is matched with the track shoe, the buffer between the bottom plate and the track shoe is increased, the lower layer of the rubber block is embedded into the bottom plate, the dual buffer and shock absorption effects are achieved, the thickness of the lower layer of the rubber block is reduced, the heat dissipation of the rubber block is facilitated, the block falling problem caused by heat damage is prevented; according to the invention, the landing rubber block and the track shoe are fixed by the bolts, when the rubber block is damaged or the service life of the track shoe is up, the landing rubber block can be detached by using a simple tool such as a socket wrench and the like for replacement, the use of the track shoe is not influenced, and the maintenance cost is reduced; the upper layer of the rubber block is rigidly connected with the track plate and flexibly connected with the track plate, so that the buffer effect is achieved under the condition that the strength is ensured, the lower layer of rubber block is embedded into the bottom plate to protect the track, in addition, the thickness of the lower layer of rubber block is reduced, the cohesive energy can be better released, the heat dissipation performance of the rubber block is improved, and the integral service life of the tank track is prolonged; the invention is mainly applied to a tracked vehicle moving system.

fig. 3 is a schematic view of the bottom plate structure of the present invention.

Detailed Description

The technical scheme of the invention is further described in detail in the following with the accompanying drawings of the specification.

As shown in fig. 1 and 2, the detachable rubber landing pad of the tracked vehicle comprises a bottom plate 4, a rubber pad 5 and a bolt 6. The bottom plate 4, the rubber block 5 and the bolts 6 are integrally vulcanized and formed, wherein the 2 bolts 6 are in interference press fit with the bottom plate 4 in a stamping mode, namely the 2 bolts 6 penetrate through the bottom of the bottom plate 4. The outer thread portion of the bolt 6 is used for connecting the track shoe 2. One part of the rubber block 5 is flexibly connected with the track shoe 2, and the other part is embedded in the bottom plate 4.

The rubber landing pad 1 of the present invention is connected to the track shoe 2 by a nut 3 and a bolt 6.

As shown in fig. 3, the bottom plate 4 is in a bowl-shaped structure, a plurality of through holes 7 are formed in the bottom of the bowl-shaped structure, the rubber block 5 is vulcanized to two sides of the bottom plate 4, namely, one part of the rubber block 5 is located outside the bottom of the bowl, the other part of the rubber block is located inside the bowl, and the two parts are combined into a whole through the through holes 7 to achieve structural communication.

The bottom plate 4 is of an equal-thickness structure and is formed by stamping spring steel materials. The bottom plate is provided with two opposite-shaped hole rectangles, prisms, triangles and the like in a stamping or machining mode and used for pressing bolts, so that the bolts are prevented from axially rotating, and the center distance of the two rectangular holes can be adaptively adjusted according to the interface of the track shoe. In addition, a plurality of through holes are reasonably arranged on the bottom plate, so that the upper layer and the lower layer of the rubber block are combined into a whole through the holes in the vulcanization process, and the dual composite strength is realized. Glue the cooperation of piece upper strata and grip-pad, increased the buffering between bottom plate and the grip-pad, glue inside the embedding bottom plate of piece lower floor, play two absorbing effect of buffering, the thickness of attenuate rubber block lower floor more does benefit to and glues the piece heat dissipation simultaneously, prevents to fall the piece problem because of the thermal damage causes, promotes the life who lands the rubber block.
