<p>A constant velocity coupling (10, 305) which rotatably connects an input shaft (11) to an output shaft (12) by means of a control mechanism or control system (21, 309) which in one form includes a gimbal arrangement comprised of an inner yoke (22) rotatably connected to an outer yoke (16). The control mechanism including control yoke (21) constrains at least portions of the coupling to lie on or in association with a homokinetic plane (300) of the coupling. The control mechanism operates symmetrically about supplementary angle bisector (308). In another arrangement the coupling includes a double constant velocity joint in which the control mechanism is located in a control tube connecting the two joints. In another arrangement the angle between the input shaft (11) and the output shaft (12) is controlled so as to vary the volumetric capacity of a swash plate hydraulic displacement device.</p> |
