Abstract
A driveshaft containment system and a method of its use. In preferred embodiments, the invention takes the form of a two component system including a first component mounted to a device such as a differential housing, coupled to driveshaft, and a second component comprising a tubular driveshaft containment housing. A driveshaft containment ring is preferably mounted to the forward end of the tubular housing which in turn is provided with a mechanism at its rearward end for rotationally engaging and disengaging the first component. The first and second components are also provided with a mechanism for preventing relative rotational movement of the first and second components while engaged with one another.

A driveshaft containment system for a vehicle having a driveshaft coupled to another driveline device, comprising:
- a first component mounted to the driveline device and a second component comprising a tubular housing containing a portion of the driveshaft and having first and second open ends, wherein the first and second components are provided with a mechanism for rotationally engaging and disengaging the first end of the tubular housing from the first component and wherein the first and second components are further provided with a single mechanism for preventing relative rotational movement of the first and second components while engaged with one another;
- wherein the rotational engagement mechanism comprises a set of projections extending from the first end and a corresponding set of openings through the first component, into which the projections are inserted;
- and
- wherein the projections comprise a set of tangs extending from a set of locations around the first end of the tubular housing and having free ends extending circumferentially from those locations and wherein the openings comprise slots configured to simultaneously allow passage of the tangs therethrough.
A method of mounting a driveshaft containment system, comprising:
- mounting a first component to a driveline device coupled to the driveshaft;
- and
- mounting a second component around a portion of the driveshaft, the second component comprising a tubular housing having first and second open ends, the mounting comprising rotationally engaging the first end of the tubular housing with the first component and by thereafter employing a single mechanism for preventing relative rotational movement of the first and second components while engaged with one another;
- wherein the rotational engaging comprises mechanism comprises engaging a set of projections extending from the first end and a corresponding set of openings through the first component, into which the projections are inserted;
- and
- wherein the projections comprise a set of tangs extending from a set of locations around the first end of the tubular housing and having free ends extending circumferentially from those locations and wherein the openings comprise slots configured to simultaneously allow passage of the tangs therethrough.
