ES2292323A1 - Multi-use universal rotation transmission system (solar) - Google Patents

Abstract

The invention relates to a novel rotation transmission system which is suitable for all types of vehicles, industrial machinery, robots and electric household equipment. The inventive system can be coupled to any type of mechanism that is propelled by a motor or by human force. The invention can easily transmit a rotational movement to a drive wheel using all of flywheels, bearings and a drive shaft. The bearings do not have to be synchronised for said system. The rotational movement can be transmitted simultaneously in different directions. The gear change can be automatic or manual and the number of forward and reverse gears can be varied as required.

Description

Universal gearbox

Object of the invention

The present invention relates to a box of changes, specifically to a box that allows a wide range of output speeds, at the expense of a single speed of entry, and both in a direction of rotation and the opposite.

The object of the invention is to get a box of universal changes, usable interchangeably in the field of motor vehicles, in industrial machinery and even to domestic level, being adaptable to any existing mechanism in which a variable speed is required.

Background of the invention

There are multiple solutions on the market techniques for gearboxes or transmissions, adapted to different types of mechanisms, such as cars, motorcycles, boats, airplanes, power generators, appliances, etc.

Each gearbox is designed and structured for a given practical application, so which is not usable in any other case.

This "individual" character of the boxes of changes, adaptable to respective specific mechanisms, impact very negatively in terms of manufacturing costs, being obviously it would be desirable to have a gearbox for use "universal", that is usable with devices substantially different from each other.

Description of the invention

The gearbox that the invention proposes solves the problem fully satisfactorily previously exposed.

To do this and more specifically the box of changes that are recommended are constituted from an axis of entry with its corresponding steering wheel, input shaft with respect to which the output axis is perpendicular, materializing the latter in a telescopic axis that receives through its free end to a gear in susceptible clutch functions of engaging in a series of toothed rings both inside and outwardly, they receive the rotational movement of said flywheel associated to the input shaft, with the special feature that in contrast to the aforementioned steering wheel incorporates a second steering wheel, of the same characteristics, which also meshes with the toothed rings mentioned above, and so that this second steering wheel, parallel to the first, turns in the opposite direction.

It is also planned the existence of two sets of toothed rings, in radial opposition, so that in function that the gear or clutch is interlocked with a ring Toothed by one or the other of the respective groups, you can invest the direction of rotation on the output shaft.

The displacement of the telescopic axis in one or another direction, to determine the positioning of the gear or clutch, can be carried out manually or by hand automatic, acting on the corresponding actuator.

The mechanisms described are housed in the inside a housing, in which the bearings are established or bearings for the aforementioned shafts.

This way you get a gearbox It offers a variety of speeds, both forward as reverse, as much as the number of rings teeth set between the two aforementioned flyers, which allows even its use as a brake.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of this description, a single drawing where with illustrative and non-limiting nature, has been represented schematically and in diametral section, a gearbox performed in accordance with the object of the present invention.

Preferred Embodiment of the Invention

In view of the review figure you can Observe how the gearbox proposed by the invention is structured from an input shaft (1), located for example in correspondence with the "Y" axis of a coordinate system Cartesian, which must supply the movement to an output shaft (2), in the practical embodiment of the figure along the "X" axis of said Cartesian coordinate system.

The shaft (1) penetrates inside a housing (3) which houses all the mechanisms constituting the cashier changes, and is finished off in a steering wheel (4) endowed with a plurality of serrated and annular crowns (5), concentric with the "Y" axis and at different distances from it, forming two groups radially opposed, as seen in the figure.

With each of these ring crowns (5) Gear a toothed ring both externally and internally, establishing two groups of rings, a first group (6) corresponding to forward transmissions, and a second group (7) corresponding to gear transmissions behind.

The two groups of toothed rings (6-7) constitute a kind of rectilinear tunnel (8) through which the second axis (2) is through, with a sector end (2 ') longitudinally immovable and a second sector (2) which is the one that is telescopically scrollable with the collaboration of an actuator (9) that can be interchangeably manual or automatic

In any case and through the actuator (9) travels longitudinally on the sector (2 ') of the axis the mobile sector (2) topped by its internal limb in a gear or clutch (10) capable of engaging, and consequently receiving the movement, to any of the toothed rings (6-7) previously cited, so that from of the deadlock situation shown in the figure, in which no there is movement transmission, several speeds of rotation for the output shaft (2) in the forward direction, when the clutch (10) is coupled to any one of the toothed rings (6), or respective reverse speeds when doing so at serrated rings (7) of the other group.

The toothed rings (6 and 7) are located between the said handwheel (4) associated to the input shaft (1), and a second flywheel (11) parallel and opposed to the first, mounted with freedom of rotation on the housing (3), and like the axles (1) and (2-2 ') are mounted on said housing through  of bearings (12).

Claims (3)

1. Universal gearbox, characterized in that incorporating a housing (3) that houses its mechanisms, consisting of a steering wheel (4) in solidarity with an input shaft (1) provided with a plurality of toothed and annular crowns (5) of different diameters, through which said input shaft (1) transmits the movement to an output shaft (2), arranged at 90 ° with respect to the input shaft, with the particularity that with said input flywheel (2 ) engage a plurality of rings (6-7), serrated both externally and internally, in diametral alignment, which form a kind of tunnel (8) through which the telescopic output shaft (2) is through, whose sector is axially movable (2) is topped by its internal end in a gear or clutch (10) attachable to any of the toothed rings (6-7) and assisted by an actuator (9), also incorporating a second flywheel (11), parallel to the first and located on the opposite side of the toothed rings ( 6) and (7), this second handwheel (11) being mounted with freedom of rotation on the housing (3). 2. Universal gearbox, according to claim 1, characterized in that the second steering wheel (11) also has annular gear crowns (5) that make said steering wheel rotate in the opposite direction to the main steering wheel (4). 3. Universal gearbox, according to previous claims, characterized in that the toothed rings (6-7) form two groups located in diametral opposition, so that the toothed rings of a cluster (6) generate a certain direction of rotation on the shaft output (2), while the toothed rings (7) of the second group generate a counter-clockwise rotation in said output axis (2).
