3349993 XCMG GR2605 motor grader driven plate
Introduction
3349993 driven plate is a core friction transmission component in the clutch system of construction machinery, also known as clutch driven disc or friction plate. It smoothly transmits engine torque through tight combination of double-sided friction materials with the flywheel and pressure plate, and features a built-in torsional damper structure to effectively absorb transmission shocks and vibrations, protecting gearbox and drivetrain components. Constructed with highly wear-resistant friction materials, high-strength steel plate hub, and precision damping spring assembly, it ensures stable performance and long service life under heavy-duty, high-frequency clutch operation conditions.
Technical Parameters
- Model: 3349993
- Type: Dry single-plate friction clutch driven plate (with torsional damper)
- Structure: Steel plate hub + double-sided friction linings + spline hub + torsional damping springs
- Materials:
- Hub: 65Mn or 50CrVA high-carbon spring steel
- Facing: Ceramic-based/copper-based powder metallurgy or non-asbestos organic friction material
- Damper springs: 60Si2Mn alloy spring steel
- Friction outer diameter: Standard matching size (fits corresponding model clutch assembly)
- Spline specification: Internal involute spline, matches gearbox input shaft
- Friction coefficient: Stable μ=0.35–0.45
- Torsional damping angle: ≥10°
- Operating temperature: -30℃～250℃
- Maximum speed: ≥4000r/min
- Features: Vibration and noise damping, wear and heat resistance, smooth engagement, high torque transmission, strong anti-fade performance
Application Scenarios
Specifically designed for main clutches of heavy construction machinery such as loaders, bulldozers, graders and forklifts, mainly installed between engine flywheel and gearbox input shaft. Suitable for:
- Heavy-duty starting, frequent shifting, and load clutch operation conditions
- Off-road scenarios with high dust and harsh environments like construction sites, mines and docks
- Transmission systems requiring smooth high-torque transmission and shock buffering
- Matching dry single-plate clutch assemblies of corresponding models
Common Faults & Troubleshooting
- Excessive wear & slippage: Caused by long-term heavy-duty operation. Symptoms: insufficient power, poor starting, slow acceleration. Replace 3349993 driven plate.
- Facing burning, hardening & cracking: Caused by excessive slipping or overheating. Friction coefficient drops and severe slippage occurs. Replace immediately.
- Damper spring breakage & looseness: Caused by excessive transmission shock or aging. Symptoms: idle noise, shifting shudder. Replace driven plate and inspect pressure plate and flywheel.
- Spline tooth wear & backlash: Caused by poor spline fit or insufficient lubrication. Symptoms: transmission noise, axial movement. Replace driven plate and inspect mating spline shaft.
- Loose or exposed rivets: Caused by poor assembly or severe impact. May scratch flywheel and pressure plate. Replace driven plate immediately and repair or replace damaged driving plates.
