Abstract
A driveshaft assembly for a vehicle includes a tube having a first end and a second end. The driveshaft assembly also includes a first member configured to transmit torque. A portion of the first member is provided within the first end of the tube and is coupled to an inner surface of the tube by a weld. The driveshaft assembly also includes a second member configured to transmit torque. A portion of the second member is provided within the second end tube and is coupled to the inner surface of the tube by a weld. The first and second members are configured to have axes of rotation that are collinear with an axis of rotation of the tube such that when the first and second members are coupled to the tube, no further alignment between the tube, the first member, and the second member is required.
