Abstract
The invention discloses a differential hollow half axis for an electric tricycle, belonging to the technical field of the electric tricycle. The differential hollow half axis consists of three sections, namely a variable-diameter round pipe, a wheel coupling shaft head and a differential gear coupling shaft head which are assembled by a temperature difference method interference tight fit process. The wheel coupling shaft head, the differential gear coupling shaft head and the variable-diameter round pipe are all formed by adopting a cold-extruding process, so that the raw materials are saved, the production efficiency is improved, the mechanical properties of the shaft heads are improved, and the accuracy and the surface roughness of the shaft heads are improved. For unit weight of a hollow pipe, the torsion strength is high, and the bending-resistant stiffness is large, so that the differential hollow half axis is applicable to high-speed rotation. The three sections of the hollow half axis disclosed by the embodiment of the invention are assembled by the temperature difference method interference-fit process or a welding method.
