Title:
POWER TRANSMISSION SHAFT AND PROPELLER SHAFT
Document Type and Number:
WIPO Patent Application WO/2024/057747
Kind Code:
A1
Abstract:
The present invention is related to a propeller shaft (PS1) that is a power transmission shaft, in which a first collapse length (S1) of a first joint member (J1) that bends on the basis of a first bending load is set to be longer than a second collapse length (S2) of a second joint member (J2) that bends on the basis of a second bending load that is greater than the first bending load. As a result, even when an axial load is applied from the first end portion (11) side, the second end portion (12) side, or both of the first end portion (11) side and the second end portion (12) side, the second joint member (J2) can be smoothly inserted into a tube (1), and the collision performance of the propeller shaft (PS1) can be stabilized.
