Component Type: These are heavy-duty truck thrust rods (also known as tie rods or thrust rod assemblies). They are used to connect the frame to the rear axle (or balance shaft), transmitting traction and braking forces while limiting rear axle displacement to ensure driving stability, especially under heavy loads.

Structural Features:

• Main body is long and rod-shaped, with spherical bearings (or ball joints) at both ends and a threaded adjustment section in the middle (used for length adjustment to compensate for suspension wear or assembly clearance).

• Surface has a black coating (rust-resistant and wear-resistant), with some rods featuring anti-slip textures for easier turning during installation.

• Equipped with white labels (indicating part numbers, batch numbers, specifications, etc.) for traceability and assembly purposes.

Functions:

• Power Transmission: Transfers the engine’s traction or braking forces from the frame to the rear axle, driving the wheels or decelerating the vehicle.

• Suspension Stabilization: Limits lateral and longitudinal displacement of the rear axle, preventing axle misalignment or bouncing under heavy loads, thereby improving driving safety.

• Cushioning and Vibration Damping: Works in conjunction with leaf springs, shock absorbers, and other components to reduce the impact of road vibrations on the frame and rear axle.
