Good chemical stability Brake fluid has been used under high humidity for a long time.1. The following briefly introduces the influence of brake fluid on the braking performance of wheel loader. Suitable high temperature viscosity, low freezing point and low temperature viscosity. The author believes that the quality of brake fluid and brake pads is also an influencing factor. (2) Proper lubricity
In order to keep the brake cylinder and rubber bowl sliding well, the brake fluid is required to have proper lubricity. Introduction In recent years, the brake system failures of loaders have become an increasing trend, especially a series of problems such as brake failure, temperature rise of the brake system, and oil from the vent of the brake pump. Loader’s performance requirements for brake fluid (1) Good viscosity-temperature performance and low-temperature performance Loaders often work in harsh working environments such as mountains and mines,
so the working method of the loader requires that the loader be in each working cycle Frequent forwards and reverses, the brake pads are in a braking state for a long time, so during the braking process, the temperature of the friction pads can reach 250°C due to frictional heat. In recent years, Mechanical Bearing 607 the brake system of loaders has become the main factor in the upward trend. 2. Therefore, the brake fluid should have good adaptability to rubber seals to prevent The rubber seal and the leather cup swell due to the incompatibility of oil and reduce the mechanical strength. (6) Good adaptability to rubber. Part of its heat is transferred to the brake fluid, so that its working temperature can reach 70℃~90℃. (3) Ensure that the braking is safe and reliable without generating air resistance.
The brake fluid temperature in Northwest and Northwest regions can be as low as -40℃, so the brake fluid is required to have good viscosity-temperature performance and low-temperature flow performance.. When frequent braking is required in mountainous environments, its working temperature can reach 110℃, sometimes as high as 150℃.
