The present disclosure relates to a driveshaft containment apparatus more specifically, but not by way of limitation, more particularly to a bracket which encompasses a driveshaft for restricting mobility of the driveshaft during a ruptured driveshaft event.
Driveshaft failure can result in catastrophic damage to the vehicle and under some circumstances severe injury or death to the occupants. Driveshaft failure can cause major damage to transmission, transfer case, wiring harness, fuel lines, front differential, and rip the floor out of the truck cab and in some circumstances resulting in damages in excess of $20,000.00. Typically, during failure the transmission and transfer case will result in holes punched through the side from the flailing driveshaft, the wiring harness and fuel lines may also be ripped out, the front differential can get cracked or bent, and the cab floor may have holes punched right through or has been ripped away under drivers feet. Current systems and methods for addressing driveshaft failure consist of one or more of the following shortcomings: insufficient confinement of the driveshaft in all directions, invasive and arduous installation onto the vehicle, and bulkiness and excessive component composition increasing materials costs, maintenance and repair.
