The friction pads on a wheel loader are a critical component, primarily used in several key systems for power transmission, speed control, and braking.
Common Characteristics and Maintenance Points of Friction Pads
Wearing Parts: All friction pads are consumables and need to be replaced periodically based on usage and inspection results.
Inspection and Replacement Standards: Primarily focus on "thickness." When the friction material wears to the manufacturer's specified minimum thickness (or the wear indicator is exposed), it must be replaced. Additionally, replacement is also necessary for cracks, severe burning (blue-black, surface hardening), indelible oil stains, warping, etc.
Pair/Set Replacement: Within the same brake or clutch assembly, friction plates (or mating steel plates/pressure plates/brake discs/brake drums) typically need to be replaced in pairs or sets to ensure uniform friction, balanced force, and optimal performance.
The friction plates of wheel loaders are critical wear parts ensuring power transmission, smooth shifting, and driving safety. Understanding their role, structure, and common failure phenomena in different systems (clutch, torque converter lock-up, brakes) is essential for the normal operation, maintenance, and fault diagnosis of the equipment. Regular inspection, timely replacement, standardized operation, and maintaining cleanliness are key to extending the life of the friction plates and ensuring equipment reliability.
