Title:
POWER TRANSMISSION SHAFT AND PROPELLER SHAFT
Document Type and Number:
WIPO Patent Application WO/2024/057748
Kind Code:
A1
Abstract:
A propeller shaft (PS1) according to the present invention is a power transmission shaft, and is configured such that when a second collision load (F2), which is greater than a first collision load (F1) at which an anchored condition of a first insertion section (22) and a tube (1) is released, has acted thereon, an anchored condition of a second insertion section (32) and the tube (1) is released. Thus, at the time of a vehicle collision, i.e. when an axial direction load (Fx) has acted on the propeller shaft (PS1), the anchored condition of the first insertion section (22) is released before that of the second insertion section (32), allowing the order of release of the anchoring of the first insertion section (22) and the second insertion section (32) to the tube (1) to be controlled. Consequently, stability in the collision performance of the propeller shaft (PS1) can be improved.
