Bolt-In Bushing Couplings for Refuse Truck Cylinder Alignment

The patent replaces the welding process with a mechanical fastening system consisting of bolt-in bushings and coupling pins. The bushings are bolted to the mechanical components using multiple bolts, and the hydraulic cylinders are coupled to these bushings via pins that fit through aligned holes. This mechanical connection system achieves strong connections while avoiding the thermal strain and deformation problems associated with welding, thereby maintaining manufacturing precision and alignment.

The patent segments the coupling system into separate modular components: bolt-in bushings that are independently bolted to mechanical components, and coupling pins that connect hydraulic cylinders to these bushings. This segmentation allows each component to be manufactured and assembled independently without requiring complex alignment procedures during welding. The bushings can be bolted on separately, and the pins can be inserted through pre-drilled holes, significantly simplifying the manufacturing process while maintaining durability.

The patent creates a dynamic, disassemblable connection system using bolt-in bushings and coupling pins instead of permanent welded joints. The bushings can be unbolted and replaced, and the coupling pins can be removed and reinstalled, allowing for easy maintenance and repair. This dynamic connection system maintains the strength and durability of welded joints during normal operation while enabling straightforward component replacement when wear or damage occurs, significantly improving reparability.
