Abstract
Official abstract text for this publication.
A composite driveshaft includes a body having a first end, a second end, and an intermediate portion defining a driveshaft axis (DSA). The first end defines a first coupling region and the second end defines a second coupling region. At least one of the first and second coupling regions defines a virtual hinge configured to accommodate both bending moments and axial changes of the body.
First claim
Opening claim text (preview).
We claim: 1. A composite driveshaft comprising: a body including a first end, a second end, and an intermediate portion defining a driveshaft axis (DSA), the first end defining a first coupling region and the second end defining a second coupling region, wherein at least one of the first and second coupling regions defines a virtual hinge configured to accommodate both bending moments and axial changes of the body; wherein the virtual hinge includes a first surface portion, a second surface portion and a third, cantilevered surface portion. wherein the first surface portion extends at an angle relative to the driveshaft axis (DSA); and wherein the first surface portion includes a first end section at the intermediate portion and a second end section at the second surface portion, the second end section defining a neck region having a diameter that is less than a diameter of the intermediate portion. 2. The composite driveshaft according to claim 1 , wherein the third surface portion extends over, at least in part, the first surface portion. 3. The composite driveshaft according to claim 1 , wherein the second surface portion defines a bend region. 4. The composite driveshaft according to claim 1 , wherein the virtual hinge is formed from one or more material sheets including one or more of a flexible matrix composite material, a rigid matrix composite material, and a hybrid matrix composite material.
