<p>PCT No. PCT/GB94/00055 Sec. 371 Date May 17, 1995 Sec. 102(e) Date May 17, 1995 PCT Filed Jan. 12, 1994 PCT Pub. No. WO94/16244 PCT Pub. Date Jul. 21, 1994A continously-variable-ratio transmission ("CVT"), for instance of the toroidal-race rolling-traction type, capable of geared neutral and of operating in at least two regimes and including a ratio-varying component ("variator"), a power-recircuiting epicyclic, a final drive shaft connectable with the variator by way of one of two alternative driven shafts and an input epicyclic the input of which is connectable to a prime mover and the two outputs of which are connected to the two alternative driven shafts respectively. One of the regimes includes a "geared neutral" condition, and the power-recirculating epicyclic is associated with clutches whereby power is recirculated through it in that regime. In the remaining one or more regimes no power is recirculated within that epicylic, but drive reaches the CVT output by way of appropriate clutches and whichever of the two driven shafts will rise in speed as that regime proceeds.</p> |
