Boron carbide aluminum driveshaft tube

摘要

The invention provides a tube assembly containing an extruded torque tube (12) and two yokes (14) welded to either end of the tube. The tube is made from a base material metal and boron carbide particles in a ratio of approximately between 2:1 to 10:1 by weight. In another embodiment, a driveshaft assembly includes the above tube assembly with a front universal joint (24) and slip yoke (26) attached to a front end, and a rear universal joint (22) attached to a rear end. An axle yoke (28) is coupled at the rear universal joint (22).
