Foton Suspension Mechanism Assembly-1

Lower Pull Rod Assembly (Dual): The primary links connecting the tractor’s draft arms to the implement hitch points, transmitting draft forces. These are central to the three-point hitch lower link function.

Left/Right Lower Pull Rod Seat Weldment: Reinforced mounting brackets that securely anchor the lower pull rod assemblies to the tractor chassis, ensuring structural integrity under heavy loads.

Extensible Guide Pipe Weldment: A telescopic housing that guides and protects the adjustable limiting rod, maintaining alignment during extension/retraction.

Extensible Rod Ball Assembly: A pivotal ball joint integrated into the limiting rod system, enabling smooth articulation while transmitting force to the implement.

Round Board: Likely a mounting plate or reinforcing disc within the assembly structure.

Limit Rod Assembly: The main adjustable linkage responsible for restricting the implement’s side-to-side movement (sway).

Limiting Rod Adjusting Screw: Allows precise manual adjustment of the effective length of the limit rod assembly, directly controlling the allowable sway range.

Left/Right Limiting Rod Bracket Weldment: Heavy-duty welded brackets mounted to the tractor chassis, providing the anchor points for the limit rod assembly.

Limiting Rod Connecting Pin (Dual) & Limiting Rod Rear Connecting Pin: Hardened pins creating pivotal connections between the limit rod assembly, its brackets, and the implement or lower pull rods.

Limiting Rod Lock Pin Assembly: Secures the adjusted position of the limiting rod assembly, preventing unintended slippage during operation.

8.8-A3L Stud: A high-tensile strength metric stud (Grade 8.8, indicating tensile strength; A3L likely specifies length/threading) used for critical, high-stress mounting points requiring exceptional shear and tensile strength.

Cover: Protects internal components or seals an access point within the mechanism.

Bolt: General fastening for structural components.

Pin (Multiple): Hardened pins used for pivotal connections throughout the linkage and bracket system.

Nut (Multiple) & Nut (PAGE81): Used with studs, bolts, and adjusting screws for secure fastening. “PAGE81” may reference a specific size/type in a manual.

Washer & Spring Washer: Distribute load and prevent loosening under vibration (spring washers provide locking tension).
