Front suspension, front leaf spring. The outer hinge pin on the right front bracket is the hinge shaft connecting the front leaf spring and the frame bracket; the leaf spring bushing is fitted onto this pin, and when the vehicle is heavily loaded and jolts, the leaf spring swings around this pin.
1. Hinge shaft: As the rotation point of the front leaf spring, during vehicle jolting, the leaf spring can swing and deform around this pin, achieving shock absorption and buffering;
2. Load transmission: Transmits the vertical load and longitudinal impact force between the frame and the front axle, and withstands the huge shear force caused by heavy loads, braking, and starting;
3. Positioning fixation: Cooperating with the bushing, lock plate, and end nut, it restricts the lateral displacement of the leaf spring, ensuring the positioning of the front suspension and preventing deviation.
Material: 40Cr alloy structural steel, overall quenching and tempering heat treatment, surface hardening for wear resistance;
• Structure: The shaft body of the pin is equipped with a central grease oil passage + radial oil outlet hole, one end has threads, and it is matched with a locking nut;
• Processing technology: Overall forging + fine grinding, wear-resistant and shear-resistant;
• Features: With an oil nozzle installation position, regular greasing lubrication is carried out to reduce wear.
Q: Which trucks fit?
A: Fit for Shacman Delong F2000, F3000, New M3000, X3000 front suspension.
Note: This is for right front outer position. Left front and rear spring pins have different part numbers and cannot be interchanged.
Q: Where is it installed?
A: It is the hinge pivot pin mounted between front leaf spring and frame right front bracket. The spring bushing is fitted on this pin.
Q: What is its function?
A:1.Acts as rotating pivot for front leaf spring, absorbs vibration during driving.
2. Transfer vertical load and impact force between frame and front axle, resist heavy shear force.
3. Fix leaf spring position and prevent lateral movement of suspension.
It has internal grease channel for lubrication, works together with spring bushing.
Q: Common failure problems
A: Pin surface wear, grooving, bending, thread damage. Lack of grease will accelerate bushing wear.
Symptoms: Chassis knocking noise, front wheel shimmy, excessive suspension clearance.
