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).

Claims

1. A continuous transmission system comprising a frame provided with tracks and a control carriage having a control lever journaled in a bearing and spacers connecting the control carriage to the switches in their spin shaft, shaft to the guide cutout shaft describing a conicity that allows a limited angular movement between the switches and the track, obtained through the control lever motion, by means of control arms coupled to the switch bearings, perpendicular to the spacers characterized in that it possesses two input sliding assemblies, primary and secondary, provided with a primary and a secondary input sliding gear, each coupled to a primary and a secondary driven ring, and to the switches, being said driven ring away from the drive shaft, but the same driven ring is connected to the drive ring by means of a flexible link that allows the sliding gears to tilt at an angle by means of the flexible link twisting, thus maintaining traction in relation to the main disc, provided by the drive ring and its connection to the drive shaft, which allow the longitudinal sliding of the assemblies driven by an electric motor, by combustion, by pedals or others, coupled to one of the drive shafts or to both of them;

a variant is foreseen with two output sliding assemblies, primary and secondary, each configured as the two input sliding assemblies, primary and secondary, with primary and secondary output sliding gears, each coupled to a driven ring, primary and secondary, and to the switches, wherein the driven ring is away from the drive shaft, but the same driven ring is connected with the drive ring by means of a flexible link that allows the output sliding gear to tilt at an angle by means of the flexible link twisting, thus maintaining traction in relation to the main disc;

another variant is also foreseen, being provided with at least one articulated output sliding assembly, configured by a sliding switch on an auxiliary track, an articulated drive shaft and a shaft guide mounted on the end of the auxiliary track and an auxiliary gear coupled to the switch and also coupled to the articulated drive shaft, which in turn, is supported and fastened to the auxiliary main bearing provided with a gear which is linked with two ring gears which, arranged on the same side of the gear, provide a combined motion of the output sliding assemblies, primary and secondary, and the articulated output sliding assembly and the auxiliary track articulated setting on the auxiliary main bearing allows the output assembly to rotate around the main disc.

2. The continuous transmission system according to claim 1, characterized in that its operation comprises two moments, being MP—

Maximum Power moment and MS—

Maximum Speed moment;

control lever presents three different stages;

I-Neutral=control lever is in the central position and maintains gear ratio stable where it currently is;

II-Speed=Pushing control lever forward, transmission starts upshifting, in a continuous and progressive way, while control lever is in said position;

III-Power=Pulling control lever backwards starts downshifting and consequent power increase.

3. The continuous transmission system according to claim 1, characterized in that if, for instance, the input sliding gears have an “

X”

diameter and the main disc a maximum contact diameter of “

5X” and

a minimum contact diameter of “

1X”

, equal to the “

X”

diameter of the input sliding gears, the result is a variable ratio of 1;

5 to 1;

1.

4. The continuous transmission system according to claim 1, characterized in that the control lever position forward forces the switch bearings to rotate on their spin shaft thus allowing the input sliding gears to tilt forward and advance, while rotating, towards the center of the main disc.

5. The continuous transmission system according to claim 1, characterized in that the primary drive gear drives the primary drive shaft and, in reverse rotation, the secondary drive gear drives the secondary drive shaft.

6. The continuous transmission system according to claim 1, characterized in that in the variant the sliding advance movement of the two input sliding assemblies, primary and secondary, and of the two output sliding assemblies, primary and secondary, is parallel and synchronized by the auxiliary spacers fixed in top points in the switches and bottom points in the switches.

7. The continuous transmission system according to claim 6, characterized in that in the variant the main disc drives the two output sliding assemblies, primary and secondary in reverse rotation and, simultaneously, the primary and secondary auxiliary drive gears.

8. The continuous transmission system according to claim 6, characterized in that in the variant, the drive shafts have an end fixed to the main bearings and at its opposite end pulleys, several gears or a propeller shaft and a differential can be coupled, thus obtaining a gear ratio at the output assembly whose result will be the input assembly square ratio.

9. The continuous transmission system according to claim 6, characterized in that in the variant, the drive shafts can be used in conjunction with the main disc, thus allowing independent drives with different speeds for different attachments.

10. The continuous transmission system according to claim 1, characterized in that in the variant, the combined motion of the output sliding assemblies, primary and secondary, and the articulated output sliding assembly provide a gear ratio whose result will be the input assembly square ratio. Auxiliary track articulated setting enables adaptation of the drive shaft angular positioning.

11. The continuous transmission system according to claim 1, characterized in that in the variant, the main disc, driven by the input sliding assemblies, primary and secondary, drives the auxiliary gear and its articulated drive shaft wherein it can be coupled to any attachment, and which can be used in conjunction with the main shaft, thereby allowing independent drives with different speeds for different attachments or the same speeds for differently positioned attachments.

12. The continuous transmission system according to claim 1, characterized in that an automation is foreseen, including electronic management of manner of use and components power (engine, transmission and attachments or traction) by connecting pneumatic, hydraulic or electrical mechanisms for sliding the control carriage, the two input and output sliding assemblies, primary and secondary, switch linkage, as well as the two output sliding assembly linkage and slide, primary and secondary, in its variant and the articulated output sliding assembly linkage, in its variants.
