<p>Vehicle driveline joints presently restrict shaft angularity, which results in lengthy driveshafts, whilst conventional flexible drives using links become too large in diameter when matching vehicle spring movements. The drive comprises hardened driving and driven flanges (1a, 1b), each with three, equally spaced, deep, radial grooves, facing one another, to entrap a concentric unit, consisting of three driving arms (3, 4, 5), journalled together at their centre, but each separately, rotatably mounted. Each arm has a roller (2) at its extremity running in a respective groove and is cranked such that one roller (2) engages driving flange (1a) whilst the other roller (2) engages identical driven flange (1b) but 180 degrees out of phase. Possible alternatives to rollers are balls, shoes, slippers or other suitable member. The arrangement permits drive to be transmitted between the flanges whilst the rotational axes are laterally displaced.</p> |
