double offset joint = cosntant velocity slip joint = Gleichlauf-Verschiebegelenk, Gleichlauf-Topfgelenk
("inboard joint" used when referring to the inner joint of a driveshaft of a fwd vehicle), cf. constant volocity joint, constant velocity fixed joint

constant volocity joint = CB-joint = homokinetic joint = Gleichlaufgelenk (universal joint in which the output shaft rotates at constant angular volocity wiht no cyclic variations, given a constant input shaft speed. Almost universally used in fwd drive shafts, but also in jointed shafts requring minor diffraction angles)

constant velocity fixed joint = outboard (universal) joint = Birfield joint = Gleichlauf-Festgelenk ("output" joint used when referring to the outer joint of a driveschaft of a fwd vehicle)

fwd = forward wheel drive = Frontantrieb
