Description

Technical Field

[0001] This utility model relates to the field of heavy-duty tracked self-propelled vehicle technology, specifically to a chassis track expansion slider mechanism. Background Technology

[0002] When the extended track of a heavy-duty tracked self-propelled vehicle is in operation, it extends and retracts within the cavity of a nylon slider installed on the chassis. During this process, the outer wall of the extended track comes into contact with the inner wall of the nylon slider cavity, generating friction. This increases the operating resistance of the extended track during extension and retraction. Therefore, it is necessary to periodically apply grease to the outer wall of the extended track to increase lubrication and reduce operating resistance.

[0003] Current technical solutions typically involve applying grease to the portion of the chassis extension rail that extends beyond the nylon slider. However, this approach has two drawbacks: firstly, uneven application of grease to the outer wall of the chassis extension rail can lead to localized wear at the contact points between the nylon slider and the chassis extension rail; and secondly, it can result in the portion of the chassis extension rail located inside the nylon slider not receiving effective lubrication. Utility Model Content

[0004] The purpose of this utility model is to provide a chassis rail expansion slider mechanism to solve the technical problems in the prior art, such as local wear caused by uneven application of grease to the outer wall of the chassis rail expansion and ineffective lubrication of the part of the chassis rail expansion located inside the nylon slider.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A chassis rail expansion slider mechanism includes a nylon slider with a cavity structure. A chassis rail is movably inserted into the cavity of the nylon slider. A nylon slider baffle is provided at one end of the nylon slider. An oil injection main pipe is provided inside the nylon slider. One end of the oil injection main pipe is connected to an oil injection hole provided on the nylon slider baffle. The end of the oil injection main pipe away from the nylon slider baffle is connected to an oil injection branch pipe provided inside the nylon slider. The end of the oil injection branch pipe away from the oil injection main pipe is connected to the inner wall of the cavity of the nylon slider.

[0007] Furthermore, the oil injection manifold includes several oil injection manifolds I and II arranged at equal intervals and in an alternating manner.

[0008] Furthermore, the end of the oil injection pipe I that is away from the main oil injection pipe is connected to the top wall and bottom wall of the cavity of the nylon slider 1.

[0009] Furthermore, the end of the oil injection pipe II furthest from the main oil injection pipe is connected to both sides of the cavity of the nylon slider 1. The beneficial effects achieved by this invention are:

[0010] This invention incorporates a main oil injection pipe and branch oil injection pipes within a nylon slider. The main oil injection pipe connects to the oil injection hole, while the branch oil injection pipes connect to the inner wall of the nylon slider's cavity. This allows grease to enter the branch oil injection pipes through the main pipe during oil injection and then seep out from various points on the inner wall of the nylon slider's cavity, thus evenly coating the outer wall of the chassis rail. This effectively avoids the technical problem of localized wear between the chassis rail and the nylon slider. Simultaneously, because the branch oil injection pipes are located inside the nylon slider, they can also lubricate the portion of the chassis rail located within the slider, thus solving the problem of ineffective lubrication in this area and significantly improving the stability and service life of the chassis rail sliding mechanism.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The following is in conjunction with the appendix Figure 1-3 To further describe this application in detail, an embodiment of this application discloses a chassis rail expansion slider mechanism. Referring to the accompanying drawings, it includes a nylon slider 1 with a cavity structure. The chassis rail expansion 2 is movably inserted into the cavity of the nylon slider 1 and can freely extend and retract within the cavity. A nylon slider baffle 3 is provided at one end of the nylon slider 1 to limit its movement.

[0018] The nylon slider 1 is equipped with a main oil injection pipe 4. One end of the main oil injection pipe 4 is connected to an oil injection hole 5 provided on the nylon slider baffle 3, through which lubricating grease can be injected into the main oil injection pipe 4. The end of the main oil injection pipe 4 away from the nylon slider baffle 3 is connected to multiple oil injection branch pipes 6, including oil injection branch pipe I 601 and oil injection branch pipe II 602, which are spaced equally and cross each other inside the nylon slider 1.

[0019] Among them, the end of the oil injection pipe I 601 away from the main oil injection pipe 4 is connected to the top and bottom walls of the cavity of the nylon slider 1, and the end of the oil injection pipe II 602 away from the main oil injection pipe 4 is connected to the two side walls of the cavity of the nylon slider 1, so that the grease can seep out from each inner wall position of the cavity of the nylon slider 1.

[0020] When the chassis extended rail 2 needs to be lubricated, grease is injected into the main oil injection pipe 4 through the oil injection hole 5. The grease flows along the main oil injection pipe 4 and enters each oil injection branch pipe 6. Then it seeps out from the top wall, bottom wall and side walls of the cavity of the nylon slider 1 and is evenly coated on the outer wall of the chassis extended rail 2, so that the part of the chassis extended rail 2 located inside the nylon slider 1 can be fully lubricated.
