The invention relates to the technical field of new energy automobile transmission, and discloses an automobile transmission shaft supporting structure which comprises a shaft pipe and further comprises a lubricating mechanism arranged in the middle of the shaft pipe and a cushioning mechanism arranged on the outer side of the lubricating mechanism. The lubricating mechanism comprises a fixing unit arranged in the middle of the shaft tube and a response unit arranged in the fixing unit. The fixing unit is used for limiting the movement range of the shaft tube; the response unit is used for triggering lubrication action; the fixing unit comprises a plurality of rollers arranged in the middle of the shaft tube in an annular array mode, a lantern ring jointly arranged on the outer sides of the rollers and a plurality of positioning holes formed in the two sides of the lantern ring in an annular array mode. Through the arranged lubricating mechanism, lubricating can be automatically conducted when the friction force between the transmission shaft and the supporting structure reaches a certain threshold value, vibration energy of the transmission shaft can be absorbed and dispersed, and supply of a lubricating agent can be automatically stopped after the lubricating condition meets the requirement.
