Abstract
Official abstract text for this publication.
An impact energy absorbing propeller shaft may include a collet integrally and rotatably inserted between a spline portion formed on an outer circumferential surface of a front shaft and a spline portion formed on an inner circumferential surface of a rear shaft, and an O-ring fitted with an outer circumferential surface of a rear end portion of the collet, fixedly holding a rear end portion of the front shaft, and fixedly supporting the collet inside the rear shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. An impact energy absorbing propeller shaft, comprising: a collet integrally and rotatably inserted between a spline portion formed on an outer circumferential surface of a front shaft and a spline portion formed on an inner circumferential surface of a rear shaft; and an O-ring fitted with an outer circumferential surface of a rear end portion of the collet, fixedly holding a rear end portion of the front shaft, and fixedly supporting the collet inside the rear shaft. 2. The impact energy absorbing propeller shaft of claim 1 , wherein the collet includes: an inner spline portion which is formed on an inner circumferential surface of the collet and meshes with the spline portion of the front shaft; and an outer spline portion which is formed on an outer circumferential surface of the collet and meshes with the spline portion of the rear shaft, and wherein at a time of a collision of a vehicle, the front shaft is moved to a rear side of the rear shaft while breaking the O-ring. 3. The impact energy absorbing propeller shaft of claim 1 , wherein the collet has a tapered portion which is formed at a rear end portion of the collet and tapered in an axial direction, and the tapered portion has a plurality of slits so that the tapered portion is spread out and expands by the front shaft that is moved to a rear side of the rear shaft. 4. The impact energy absorbing propeller shaft of claim 1 , wherein the collet includes a catching end which is formed at a front end portion of the collet and protrudes outward so as to prevent the collet from being moved to the rear end portion of the rear shaft. 5. The impact energy absorbing propeller shaft of claim 1 , wherein a static load in an axial direction is determined by strength of the O-ring, and the O-ring has one or more notches for adjusting strength against an axial load.
