What is the Dongfeng Suspension Mechanism

  • Dongfeng Suspension Mechanism: Precision Stability & Control for Heavy Implement Hitch Systems
    Engineered for demanding agricultural tractors, the Dongfeng Suspension Mechanism delivers superior stability, precise implement positioning, and controlled movement. This robust 3-point hitch system absorbs shock loads, prevents sway, and ensures optimal implement performance across uneven terrain, maximizing productivity and operator safety.
  • Core Linkage Adjustment & Upper Control
  • Precision Upper Link Assembly: Features the Upper Link Rear Adjusting Rod and Upper Link Front Adjusting Rod, connected via the Turn Buckle of Upper Link for fine-tuning upper link length and implement pitch. Secured by Hex .Nut M24 and Hex .Nut M16.
  • Secure Upper Mounting: The Upper Link Fixation Assembly provides a stable anchor point, utilizing the Coupling Pin of Upper Link for pivotal connection.
  • Stabilized Lift Rod Connection: The Lift Rod Upper Clevis and Lift Rod Up Clevis interface with the lift arms, connected by Clevis Pin with Head B16×80 locked with a Kock Pin and Plain Washer 16.
  • Robust Lower Linkage & Implement Interface
  • Heavy-Duty Lower Link Weldment: Forms the primary implement attachment point, pivoting on the Lower Link Shaft.
  • Integrated Lift Rod Lower Connection: The Lower Clevis of Lift Rod connects to the lower link via Clevis Pin with Head B16×45, secured with Spring Lock Washer 16 and Hex.Nut M20x2.
  • Auxiliary Fastening: Hex. Head Bolt M16×80 provides structural reinforcement where needed.
  • Comprehensive Sway Control & Check Chain System
  • Multi-Directional Stability:
  • Front Check Chain System: Includes dedicated Left-Front Check Chain, Right-Front Check Chain, and general Front Check Chain to limit lateral movement at the front of the lower links.
  • Rear Check Chain: Controls rear implement sway, completing the stability envelope.
  • Secure Chain Attachment: Chains are anchored using Clevis Pin with Head B12×45, locked with Split Pin 4×25 and Plain Washer 14, ensuring positive retention under stress.
  • Pivotal Joints, Wear Protection & Serviceability
  • Critical Articulation Points: The Cross Joint of Lift Rod enables smooth angular movement within the linkage system.
  • Enhanced Durability: Adjusting Sleeves provide wear surfaces and alignment, while Round Plates act as reinforcement spacers.
  • Maintenance Access: Grease Nipple M10x1 allows for easy lubrication of pivotal joints (Clevis Pins, Shaft) to extend service life and reduce friction.
  • Vibration Damping & Retention: A Spring element absorbs minor shocks, and R-Pins provide quick, secure locking for pins like the Kock Pin (used with Split Pin 3.2×26 for secondary security).
  • Engineered for Demanding Field Performance
    The Dongfeng Suspension Mechanism is a complete, integrated stability solution. The synergy of its adjustable linkage (Upper Link Rods, Turn Buckle), robust sway control (Front & Rear Check Chains), heavy-duty pivots (Clevis Pins, Cross Joint, Lower Link Shaft secured with M16/M20/M24 Nuts and Lock Washers), and serviceable components (Grease Nipple, Adjusting Sleeves) delivers unparalleled implement control. Designed to minimize drift, absorb impacts, and provide precise positioning, it meets rigorous OEM standards for reliable performance season after season in the toughest agricultural conditions.
