Six core application scenarios
1. Heavy-duty commercial vehicle transmission system: It is adapted to the gearbox of heavy-duty trucks and muck trucks over 15 tons. It ensures smooth shifting, avoids power interruption, and meets the needs of high-intensity operations of more than 12 hours a day under frequent start-stop and heavy-load climbing conditions.
2. Engineering machinery hydraulic system: used in the traveling motors and slewing mechanisms of excavators and loaders to resist oil contamination in muddy and dusty outdoor environments and ensure precise power transmission for bucket lifting and body steering.
3. New energy heavy truck drive axle: In view of the high torque output characteristics of electric muck trucks and port tractors, it solves the problem of easy ablation of traditional friction plates, adapts to the high-frequency start and stop requirements of motors, and improves endurance, safety and stability.
4. Ship power shifting device: used in gearboxes of inland river cargo ships and fishing boats to achieve smooth power switching between the main engine and propeller in humid and salt spray corrosive environments, adapting to complex navigation conditions on the water.
5. Mining machinery transmission components: The reduction gearboxes assembled in mining crushers and scraper conveyors can withstand impact loads and continuous high torque, maintain stable friction performance in dusty and high-temperature environments, and reduce the number of equipment shutdowns for maintenance.
6. Industrial heavy-duty winch system: Heavy-duty winches used in the fields of metallurgy and construction (such as ladle lifting, bridge hoisting), provide reliable braking and power buffering under heavy-load hovering and low-speed lowering conditions, ensuring operational safety.

The steel plate coupling plate is a transmission system supporting component made of high-strength 65Mn steel plate as the base material and processed by precision stamping, surface phosphating/galvanizing or laser hardening. Its core function is to form an efficient friction pair with the friction plate. It has a high-precision surface with a flatness error of ≤0.03mm, mechanical properties of tensile strength of ≥500MPa, and excellent wear resistance, corrosion resistance and thermal conductivity. It can maintain structural stability under high load and high-frequency friction conditions, quickly conduct heat generated by friction, avoid thermal deformation, and cooperate with friction plates to achieve smooth engagement and cut-off of power. It is an indispensable key in wet/dry transmission systems.

Ceramic fiber friction pads are made of high-performance ceramic fiber as the core friction base material, composite resin adhesive and metal reinforced particles. They have three core advantages: ultra-high temperature resistance (long-term working temperature resistance of 350°C), stable friction coefficient (0.4-0.5 in dry state, thermal decay rate ≤15%), low wear and environmental protection (the wear amount is 40% lower than that of traditional metal-based friction pads, and there is no metal debris pollution). It is light in texture, has strong thermal stability, is not easily deformed or cracked under high temperature and high-frequency friction conditions, and has excellent noise reduction properties. It is an ideal choice for transmission systems that require high temperature resistance and environmental protection.

The copper-based die-cast sintered dry friction disc is made of high-strength 65MN steel as the base material and is made through an integrated process of high-pressure die-casting and high-temperature sintering. The friction layer has a higher density and a more uniform structure. Its core advantages include stable friction coefficient (0.35-0.45) in a dry environment, strong resistance to thermal decay (continuous operating temperature up to 350°C), high mechanical strength (compressive strength ≥ 280MPa), and the ability to achieve efficient power transmission without relying on lubricating oil. It also has low wear and no oil pollution, and can adapt to complex working conditions such as dryness and dust. It is an ideal component for transmission systems that require high cleanliness and reliability.

Copper-based spray-sintered wet friction pads use high-purity copper alloy as the base material and form a porous friction layer through a precision spray-sintering process. They have three core advantages: high temperature resistance (instantaneous temperature resistance can reach more than 800°C), high friction coefficient and stability (fluctuation ≤ 0.05), and low wear rate (the wear amount is 30% lower than traditional products). Its unique porous structure can efficiently store lubricating oil, achieve rapid heat dissipation and smooth engagement in a wet working environment, without impact and noise. It also has excellent oil corrosion resistance and fatigue resistance, and its service life is far longer than that of resin-based or cast iron-based friction plates. It is a core and key part of high-load power transmission systems.
