<p>A rotary transmission of continuously-variable-ratio type including a variator (1), that is to say a ratio-varying unit, and a subsequent gearing unit (2), the gearing unit being capable of alternative settings whereby the transmission may operate in two different regimes. The axes (4, 5) of rotary operation of the variator and the gearing unit are displaced from but parallel to each other, and the entire gearing unit lies between the two radial planes (18, 19) marking the axial extremities of the variator, which may be of the toroidal-race rolling traction type with two input discs (7, 8) located at opposite axially ends and a single, double-faced output member (15) located centrally between them, that member coinciding axially with the member (45, 70) of the gearing unit to which it is connected. The means of connection may be direct geared engagement (73, 74, Figure 3), involving reversal of direction of rotation, or connection by chain (46, Figure 2), belt or the like involving no such reversal.</p> |
