The Influence And Discussion Of Brake Fluid On Loader Braking Performance (2)

When the pipes of the brake system are filled with steam and gas exists, due to the relatively high compressibility of the gas, and the brake pedal feels soft and elastic when you step on it, it means that air has penetrated into the brake fluid. The braking effect will become worse, safety will be reduced, and the braking response speed will be reduced. Especially in mountains and mountainous areas, frequent braking will increase the temperature of the brake fluid. If the boiling point of the brake fluid is low, it is easier to cause cavitation in the braking system and damage the rubber sealing ring and brake components of the afterburner pump. cause damage. This will cause the braking system to completely fail and endanger personal safety. In addition, when there is gas in the brake fluid pipeline of the brake system, when the brake pedal is released, because the expansion speed of the gas is faster than the speed of the brake fluid, sometimes a flow from the brake oil cup of the booster cylinder to the brake fluid cup will occur. The phenomenon of external oil spraying. Brake fluid with a low boiling point seriously affects the braking performance of wheel loaders. At present, most domestic wheel loaders use 719 synthetic brake fluid, which is equivalent to HZY3 of domestic GB12981-2003 and DOT3 of the international standard. The dry boiling point of this brake fluid is 205°C. The dry boiling point refers to the fluid just removed from the sealed container. The boiling point of some inferior brake fluids is lower after being added to the brake system, and some inferior brake fluids have lower dry boiling points, thus affecting braking safety.

The Influence And Discussion Of Brake Fluid On Loader Braking Performance (1)

In recent years, loader brake system failures have become an increasing trend, especially brake failure, brake system temperature rise, oil leakage from the brake pump vent, and a series of other problems. At present, almost all domestic loader service brake systems use pneumatic brake systems. Top oil caliper disc brake, the selection of brake components is generally the same as that of automobiles. There are many factors that cause the failure of the loader's braking system, such as damage to the braking components leading to braking failure. In recent years, loader braking systems have become the main factor in the upward trend. The author believes that the decline in the quality of brake fluid and brake pads is also an influencing factor. The following is a brief introduction to the effect of brake fluid on the braking performance of wheel loaders.

Railway Bearings – Characteristics And Applications Of Axle Gearbox Bearings

Tapered roller bearings are separable, and their inner ring roller cage assembly and outer ring can be separated and assembled separately. Corrected linear contact between rolling elements and raceways avoids edge stresses. Tapered roller bearings can support both high radial and axial loads. Because this type of bearing can only bear axial force on one side, it needs to be paired when used. This type of bearing is used in gear boxes and axle holding boxes.

Damage Repair Countermeasures And Maintenance Methods Of FAG Spherical Roller Bearings

When disassembling the spherical roller bearing for maintenance, first record the appearance of the FAG bearing, confirm the remaining amount of lubricant, and then wash the bearing after sampling the lubricant for inspection. As cleaning agents, gasoline and kerosene are generally used.
