Abstract: Patent of invention for a transmission comprising a frame (1) provided with tracks (2) and a control carriage (3) having a control lever (3a) journaled in a bearing (3b) and spacers (3c and 3d) connecting the control carriage (3) to the switches (4 and 5) in their spin shaft (4a and 5a), colinear to the guide cutout shaft (4b and 5b) describing (FIGS. 25 to 28) a conicity which allows a limited angular movement between the switches (4 and 5) and the track (2), obtained by the control lever (3a) motion by means of control arms (3e) coupled to the switch bearings (4c and 5c), perpendicular to the spacers (3c and 3d) making up the primary (6) and secondary (7) input sliding assemblies, and having a variant (FIGS. 14 to 21) with two output sliding assemblies, primary (9) and secondary (10), each configured as the two input sliding assemblies, primary (6) and secondary (7), and another variant (FIGS. 22 to 24) with at least one articulated output sliding assembly (15).
