Benefits of technology

This patented design helps keep lubricating oils inside an engine's housing while still allowing for efficient rotation without leakage or overheating. It also prevents excessive pressurization caused by changes made during operation due to temperature differences that may affect other parts within the system.

Problems solved by technology

This technical problem addressed by this patented describes how to efficiently remove excessive amounts of heat generated when operating vehicles under heavy load conditions while maintaining their ability to operate effectively without overheated components or causing damage caused by too much torsion force applied thereto.

Abstract

The invention provides a hollow shaft sealing ring, a hollow shaft, a rotor structure, a motor and an electric automobile, wherein the hollow shaft sealing ring is used for sealing an oil inlet of thehollow shaft, an oil pipe hole is formed in the sealing ring, an oil inlet pipe is arranged in the oil pipe hole, the outer diameter of the oil inlet pipe is R5, the inner diameter of the oil pipe hole is R4, and R4 is larger than R5. According to the semi-closed sealing structure of the hollow shaft, cooling oil can be prevented from leaking along the inner wall of the bushing cavity when the rotor rotates at a high speed while the bushing cavity can be kept communicated with the outside, and the situation that oil cannot be sprayed due to the fact that pressure difference is formed betweenair pressure of the inner cavity and the outside of the oil throwing opening is avoided.
