the hollow shaft 10 as the rod 11 slides axially in the hollow shaft 10 the ends of the transverse pins 12 extend into and couple with a coaxial sleeve 19 the sleeve 19 is fixedly attached at each end to a substantially planar platform 13 a 13 b forming a trough around the circumference of the sleeve 19 as seen more clearly in fig4 the planar platforms 13 a 13 b each contact and push multiple wheels 21 a f the wheels 21 a f fit into slots in the spindle supports 2 a f and are held in place by wheel axles 22 a f the wheel axles 22 a f are supported at their ends by the spindle supports 2 a f and allow rotational movement of the wheels 21 a f referring back to fig1 and 2 the substantially planar platforms 13 a 13 b transition into a convex surface at their outer perimeter farthest from the hollow shaft 10 this region allows slack to be taken up when the spindle supports 2 a f and power adjusters 1 a 1 b 1 c are tilted as the transmission 100 is shifted a cylindrical support member 18 is located in the trough formed between the planar platforms 13 a 13 b and sleeve 19 and thus moves in concert with the planar platforms 13 a 13 b and sleeve 19 the support member 18 rides on contact bearings 17 a 17 b located at the intersection of the planar platforms 13 a 13 b and sleeve 19 to allow the support member 18.
