7.5-Ton Front Axle Kingpin Repair Kit HD950009410045 for SHACMAN X3000 X5000 X6000 M3000 F3000 Trucks

Physical Assembly Position: Vertically mounted in the vertical pin holes at both ends of the front I-beam (front axle), the rigid front axle is tightly locked in series with the steering knuckle (commonly known as the steering knuckle), which is responsible for mounting the tires and brake discs.

Physical Linkage Mechanism: Steering Pivot Guiding: When the driver turns the steering wheel and pushes the front wheels through the tie rod, the steering knuckle rotates around this HD950009410045 kingpin, thus achieving left and right steering of the truck.

Vertical Gravity Bearing: The entire vertical weight of the truck cab and the cargo in front is directly pressed onto the front axle and transmitted to the wheels through the thrust bearing at the bottom of the kingpin. The bearing rotates at high frequency when the wheels turn, reducing friction.
