AI Technical Summary
Technical Problem
Existing adapter shaft designs are heavy, have low material utilization, high processing costs, and affect transmission efficiency.
Method used
The design incorporates an oil guide tube and a hollow shaft, allowing lubricating oil to circulate through the lubrication channels in the oil guide tube and the oil inlet and outlet holes in the shaft. This reduces the weight of the adapter shaft, improves transmission efficiency, and lowers processing costs.
Benefits of technology
This achieves effective circulation of lubricating oil, reduces the weight of the adapter shaft, improves transmission efficiency, and lowers processing costs.

Abstract
The utility model belongs to the technical field of vehicles, and discloses an oil guide pipe, an adapter shaft, a transmission device, an electric drive assembly and a vehicle, lubricating oil sequentially passes through a second oil inlet hole and a first oil inlet hole to enter a first lubricating channel, and the lubricating oil in an oil guide channel flows out to a lubricating cavity between a motor shaft and a shaft body through a first oil outlet hole and a second oil outlet hole. The motor shaft is lubricated; meanwhile, the coupling shaft mainly plays a role in transmitting the rotating speed and the torque, and the oil guide pipe and the hollow shaft body are adopted, so that the weight of the coupling shaft is reduced, the transmission efficiency is improved, few materials are used, and the machining cost of the coupling shaft is reduced.
