What is the SHANTUI Clutch (II.IV)?

  • The Clutch (II. IV) of the SHANTUI SL60W Wheel Loader represents a critical subsystem within the transmission assembly, engineered to deliver precise torque transfer and seamless gear shifting under heavy loads. These clutches (II and IV) work in tandem to manage power distribution between the engine and drivetrain, ensuring optimal performance in demanding construction and material handling applications. Below is a detailed breakdown of their key components:
  • 1. Structural & Rotational Components
  • Clutch Shaft: A forged alloy steel shaft with precision splines that interfaces with the transmission gears, providing a rigid axis for torque transfer. Dual Bearing (tapered roller and ball bearings) support the shaft, minimizing friction and ensuring alignment under high radial and axial loads.
  • Gear & Gear Sleeve: Hardened steel gears (helical cut) mesh with corresponding transmission components, while the Gear Sleeve (splined inner bore) enables smooth engagement/disengagement of the clutch. Each gear undergoes carburizing and quenching for enhanced wear resistance.
  • Baffle Ring: A stamped steel ring that directs lubricant flow within the clutch, preventing overheating and ensuring consistent performance during prolonged operation.
  • 2. Engagement & Friction System
  • Clutch Driving Disc & Clutch Driven Disc:
  • The Driving Disc (connected to the engine) features high-friction material (sintered metal) bonded to its surfaces, providing reliable grip when compressed.
  • The Driven Disc (linked to the transmission) incorporates damper springs to absorb shock during engagement, reducing drivetrain stress and extending component life.
  • Piston: A precision-machined aluminum piston that actuates clutch engagement when pressurized by hydraulic fluid. Its outer diameter is sealed with a Piston Outer Seal Ring (nitrile rubber), preventing leaks and maintaining pressure integrity.
  • 3. Hydraulic Control & Sealing
  • Check Valve Seat & Steel Ball: A one-way valve assembly that regulates hydraulic fluid flow, ensuring rapid clutch engagement and preventing pressure loss during operation. The Steel Ball (chrome alloy) seats against the Check Valve Seat (hardened steel) to maintain system integrity.
  • Seal Ring: Multiple elastomeric seals (NBR and FKM materials) prevent fluid leakage around rotating shafts and static interfaces, ensuring efficient hydraulic operation even under high pressure (up to 20 MPa).
  • 4. Spring & Retention Mechanisms
  • Spring & Spring Spacer: High-tensile coil springs provide the force to disengage the clutch when hydraulic pressure is released. The Spring Spacer (machined steel) maintains uniform spring compression, ensuring consistent performance across all clutch plates.
  • Snap Ring & Retainer Ring: These circlips secure bearings, gears, and other components in place, preventing axial movement under dynamic loads. Made from heat-treated alloy steel, they offer high fatigue resistance.
  • 5. Fasteners & Gaskets
  • Nut & Split Pin: Grade 10.9 nuts secure critical components, with Split Pins providing secondary locking to prevent loosening from vibration.
  • Gasket: Compressible fiber or rubber gaskets seal the clutch housing, preventing oil leaks and protecting internal components from contaminants.
  • The Clutch (II. IV) system integrates these components to deliver reliable, responsive power transmission, essential for the SHANTUI SL60W’s productivity in heavy-duty applications. Each part is rigorously tested for durability, wear resistance, and compatibility, ensuring seamless operation even under extreme conditions. Regular maintenance—including hydraulic fluid checks, friction disc inspections, and seal replacements—maximizes clutch lifespan, making it a cornerstone of the loader’s performance.
