ABSTRACT:
A driveshaft assembly includes a cylindrically shaped driveshaft tube and a tube yoke. The tube yoke is attached to the driveshaft tube and transfers torque between the driveshaft tube and a universal joint. The tube yoke has a first end having a tube seat for connecting the driveshaft tube to the tube yoke and a second end having lugs for connecting the tube yoke to the universal joint. The tube seat has an outer surface which is fixed to the driveshaft tube to prevent relative movement between the driveshaft tube and the tube yoke. A diamond-shaped relief formed in an end surface of the tube seat has two pairs of opposed points, with each point positioned 90 degrees from another point. Flats are formed between each adjacent points. The diamond-shaped relief is oriented to provide tube seat walls which are thickest at the locations which receive the greatest stress during rotation of the driveshaft assembly. Two of the points face the yoke lugs and the other two face at 90 degree angles away from the yoke lugs. The diamond-shaped relief reduces the weight of the tube yoke and prevents undesirable distortion of the tube seat which can weaken the union between the tube yoke and driveshaft tube.
