Problems solved by technology

Practical applications and literature data show that the following two problems are likely to occur in track bushings in practical applications, resulting in damage and failure: ① Radial extrusion caused by the huge traction force of the vehicle, and rubber layer of the bushing caused by impact and vibration forces ②The track moves to the position of the driving wheel and the induction wheel, and the axial torsion of the bushing and the track pin occurs, and the tearing damage of the bushing rubber layer is caused by the comprehensive stress of shear fatigue.

preparation example Construction

[0032] The present invention further relates to a method for preparing a single-plate single-pin vehicle track pin rubber bushing, comprising the following steps:

[0033] S1: First use the hydroxyl groups on the surface of graphene oxide and γ-chloropropyltriethoxysilane (CTS) to graft, and react to prepare graphene oxide grafted CTS; then the reaction product is further mixed with anti-aging agent 2-mercaptobenzene And imidazole (MB) undergoes grafting reaction to obtain graphene oxide grafted antioxidant MB;

[0034] S2: masticate the natural rubber in the internal mixer for 1-3 minutes, then add the compounding agent including active agent, softener, anti-aging agent, reinforcing agent and carbon fiber, and mix on the internal mixer for 3-5 minutes, then add Mix the carbon black filler for 9-11 minutes; then add accelerator and sulfur to the open mill and mix for 4-6 minutes to obtain the mixed rubber for high modulus shock-absorbing rubber rings, and test the normal vulca...

Embodiment 1

[0040] (1) Preparation process of high modulus rubber bushing

[0041] First, 5 g of graphene oxide and 15 g of γ-chloropropyltriethoxysilane (CTS) were dispersed in 400 ml of absolute ethanol, and stirred at 50° C. for 24 hours to prepare graphene oxide grafted CTS. Then add 0.5g sodium hydroxide (NaOH) and 2g anti-aging agent 2-mercaptobenzimidazole (MB), nitrogen protection, stirring and reacting for 24h, the reaction product is filtered, washed 3 times with ethanol and deionized water, and dried to obtain Graphene oxide grafted antioxidant MB.

[0042] Weigh the natural rubber and various compounding agents required for high modulus formula 1, masticate the natural rubber raw rubber in an internal mixer for 2 minutes, and then add zinc oxide, stearic acid, graphene oxide grafted anti-aging agent MB, Liquid polyisoprene and carbon fiber, mixed for 4 minutes, finally added carbon black, mixed for 10 minutes, debinding. After the rubber material is cooled, continue mixing w...

Abstract

The invention discloses bushing rubber for a single-board and single-pin vehicle track pin. The bushing rubber is prepared from components in parts by mass as follows: 100 parts of natural rubber, 30-50 parts of carbon black, 4-10 parts of carbon fiber, 2-5 parts of an anti-aging agent, 3-6 parts of an active agent, 1-3 parts of a softener, 3-8 parts of a reinforcing agent, 1-4 parts of a vulcanizing agent and 1-4 parts of an accelerant. The torsional force borne by traditional bushing rubber and dual extrusion-torsion shear loss of a rubber bushing can be improved, optimization of an overallrunning function of a track is realized, and the mileage life of the track is prolonged.

Description

technical field [0001] The invention belongs to the technical field of composite materials for armored vehicles, and relates to a single-plate single-pin vehicle track pin bushing rubber, specifically to prepare functional track pin bushing rubber, which has the advantages of anti-extrusion buffering and shock absorption, high pressure resistance, twist feature. Background technique [0002] The tank track is an important part of the tank's power action system. Its function is to transmit the driving torque or braking torque by means of the active wheel meshing with it, and rely on the interaction with the ground to generate traction or braking force to realize the movement of the tank and ensure the smooth running of the tank. Through various complex road surfaces and various obstacles. The track shoes and track pins are made of high-strength wear-resistant alloy steel. In order to reduce the huge force of the track traction on the plate body and track pins during the runn...
