Adjustable angle drive connection for a downhole drilling motor

A drive connection for a downhole drilling motor, comprising:

• a tubular outer housing having a motor end and a bit end, the tubular outer housing defining an interior bore;
• an angular offset being provided toward the bit end of the tubular outer housing;
• a tubular inner mandrel positioned within the interior bore of the outer housing, the tubular inner mandrel being comprised of:
• a motor end section;
• a bit end section;
• and
• an intermediate section connecting the motor end section and the bit end section, the intermediate section having a ball and socket providing an upper articulating engagement with radial drive members that couple the intermediate section to rotate with the motor end section and a ball and socket providing a lower articulating engagement with radial drive members that coupled the intermediate section to rotate with the bit end section, such that the motor end section, intermediate section and bit end section rotate together, with the upper articulating engagement and the lower articulating engagement accommodating rotation that is offset due to the angular offset;
• a drive shaft is positioned in the interior bore of the housing at the motor end, the drive shaft being capable of converting offset rotation of a downhole drilling motor into concentric rotation for input into the motor end section of the tubular inner mandrel;
• the tubular inner mandrel defining a central drilling fluid flow channel allowing passage of drilling fluids passage from the motor end of the tubular outer housing through the motor end section, the intermediate section and the bit end section of the tubular inner mandrel.
