BYD electric forklift brake vulnerable small parts, brake shoe sub-pump oil seal accessories introduction

The braking system of an electric forklift is the core component to ensure the safety of the operation. Although the brake shoes and the oil seals of the pump are not large in size, they perform key functions and are also accessories that are prone to wear and tear in daily use. Understanding the characteristics and maintenance knowledge of these accessories can effectively prolong the service life of the forklift and reduce safety hazards.

The brake shoe is the core small part directly involved in the braking action in the braking system. When the driver operates the brakes, the shoe will fit the brake drum under the force of the sub-pump, and the vehicle will be decelerated or stopped by friction. In daily operations, frequent braking operations, emergency braking during heavy object handling, and dust and oil adhesion in the working environment will accelerate the wear of the shoe. When the thickness of the shoe is worn below the specified limit, the braking effect will be significantly reduced, and even abnormal braking noise will occur. At this time, it is necessary to replace it in time. When choosing replacement accessories, it is necessary to ensure that their materials are suitable for the working scene. For example, in a dusty environment, the type of shoe that is wear-resistant and not easy to accumulate dust is preferred.

The oil seal of the sub-pump is an important sealing part of the brake sub-pump. Its main function is to prevent the leakage of brake fluid, and at the same time block external dust and moisture from entering the interior of the sub-pump to ensure the normal operation of the sub-pump hydraulic system. During long-term use, the oil seal will age and crack due to the chemical erosion of the brake fluid, temperature changes and repeated telescopic actions. Once the oil seal fails, it will cause the brake fluid to leak and the pressure of the sub-pump to be insufficient, which will affect the braking performance. During daily inspections, if traces of brake fluid are found around the sub-pump, the oil seal status should be checked in time and replaced if necessary. When replacing the oil seal, it is necessary to clean the installation part of the sub-pump to avoid impurities from entering, and at the same time ensure that the oil seal is installed in

For these brake vulnerable small parts, regular inspection is the key to maintenance. It is recommended to formulate an inspection cycle according to the working intensity of the forklift. Generally, an appearance inspection is carried out once a month, and a depth inspection is carried out every quarter. When checking the brake shoes, focus on the thickness, wear uniformity and whether there are cracks on the surface; when checking the oil seal of the sub-pump, pay attention to whether there are any signs of leakage and aging. In addition, keeping the working environment clean, reducing the erosion of dust and oil on the accessories, and avoiding frequent emergency braking can also effectively prolong the service life of these small parts.

Although brake shoes and sub-pump oil seals are small parts in the braking system of electric forklifts, their performance is directly related to operation safety and normal operation of forklifts. By understanding their functions, causes of wear and tear, and maintenance points, users can detect and solve problems in time to ensure that forklifts are always in good working condition.
