Balancing Force and Flexibility: The Engineering of Modern Bush Couplings

The attached image shows a 3D model of a bush coupling (also called a bushing or resilient pin-and-bush coupling), consisting of two flanges connected by a central shaft with elastomeric bushings that allow limited articulation and absorb shocks. This design is commonly used in truck-trailer fifth wheel systems, pintle hooks, or drawbar couplings to handle
