What is the Dongfeng Transmission Shaft

  • The Dongfeng Transmission Shaft forms the critical backbone for reliable power transfer in compatible commercial vehicles. This robust assembly integrates numerous precisely manufactured components to ensure smooth, efficient, and durable operation under demanding conditions.
  • Core Structure & Mounting:
  • The assembly is anchored by the sturdy Front Housing and Rear Housing, providing the primary structural framework.
  • Secure mounting to the vehicle chassis is achieved via the Fixing Bracket, utilizing high-strength Hex. Head Bolts (M8×25) paired with Spring Lock Washers (8) and Flat Washers (8). An M10×25 Hex. Head Bolt with its Spring Lock Washer (10) provides additional critical fastening.
  • Vibration damping is effectively managed by strategically placed Rubber Pads between mounting points.
  • Sealing & Protection Systems:
  • Superior contamination protection is guaranteed by multiple sealing elements: the Seal Sleeve, specialized Rubber Cover, Support Sleeve, and critical O-Ring Seal (48.7×3.55).
  • Hoops (φ53 and φ48) securely clamp flexible sealing components in place.
  • The vital Oil Seal (PG25×42×10) safeguards internal bearings from lubricant loss and external ingress.
  • A Slotted Spring Pin (4×30) and Steel Wire (I-1.4) provide additional, secure retention for specific components.
  • Shaft Assembly & Bearings:
  • Power transfer revolves around the central Transmission Shaft, connected via the Rear Connecting-Sleeve to the Rear Mid-Shaft.
  • The Mid-Shaft Housing encloses and supports this assembly.
  • Rotation is supported by a high-quality, shielded Ball Bearing (6020) seated within the Mid-Shaft Seat.
  • Precise axial location and retention are managed by Blocking Rings (2), a dedicated Seal Blocking Ring, and a calibrated Spring.
  • Lubrication & Maintenance:
  • Long-term bearing performance is ensured by easy-replenishment via a Grease Cup (M10×1), installed with a Paper Gasket for a perfect seal.
  • Steel Balls (9) are integral to specific joint mechanisms within the assembly, facilitating smooth articulation.
  • Engineered for Performance:
    Every component, from the Hex. Nut (M8) fasteners to the precisely dimensioned seals and bearings, is manufactured to exacting Dongfeng standards. This ensures the transmission shaft assembly delivers dependable power transmission, minimal vibration, and extended service life, making it a cornerstone of vehicle driveline reliability.
