A driveshaft assembly comprises a cylindrical upper member, with one end of the upper member being connected to the rotor and an other end of the upper member having a plurality of torque transmitting profiles. An elongated central member has two ends, with each end having a plurality of torque transmitting profiles. A seat is retained within a central bore of the upper member, the seat having a curved end. A catch is retained within the central member, the catch having a curved end. The upper member transfers torque from the rotor to the central member via the torque transmitting profiles of the upper member and the torque transmitting profiles of the central member, and the curved end of the seat contacts the curved end of the catch while maintaining a gap between the other end of the upper member and the adjacent end of the central member. |
