Description

Technical Field

[0001] This utility model relates to the field of precision machining technology for crank assemblies, and in particular to a precision machining device for crank assemblies used in trailer arms. Background Technology

[0002] The trailing arm is a semi-independent suspension system designed specifically for the rear wheels. Its composite structure connects the wheels to the body through a large trailing arm, and the crossbeam, together with the rotatable components, enables limited independent movement of the left and right wheels. This structure uses a combination of hydraulic shock absorbers and coil springs to buffer the system, combining the integrity of a non-independent suspension with the motion characteristics of an independent suspension. It is widely used in front-wheel-drive vehicles.

[0003] The crank assembly for trailer booms is a transmission component that connects the trailer boom to the drive mechanism. In the production and processing of the crank assembly for trailer booms, the original process was to first complete the shape machining by wire cutting and then perform CNC machining. However, in actual production, it was found that the wire cutting capacity could not meet customer demand. Therefore, the process was changed to directly perform CNC machining after forging the blank. Without changing the materials and performance, this achieved cost reduction, efficiency improvement and a significant increase in production capacity.
