Abstract

Mejoras en dispositivos de accionamiento para bicicletas y triciclos en general; del tipo en el que el vehículo de aplicacion tal como una bicicletacomprende un cuadro (a) que, hacia la zona anterior del mismo vehículo está provisto de un manubrio (1 ) de comando fijado a la parte superior de un eje dedireccion (2) el cual incluye una primera horquilla (3) en cuyo extremo (3) se monta rotativamente el eje transversal (4) de, al menos una rueda delantera(5); mientras que hacia la zona posterior, l a parte superior de dicho cuadro (a) tiene al menos fijado un asiento (6), mientras que la inferior conforma unasegunda horquilla (7) en la que, transversal y rotativamente se monta al eje (8) de una rueda trasera (9) conectada a un dispositivo de ac cionamiento (b) apedal (12); y este dispositivo de accionamiento (b) a pedal (12) está integrado por dos brazos de biela (10) los cuales, proyectados en disposicion diametralopuesta desde los extremos (11) de un eje tractor (11), terminan en sendos p edales (12) con los que comandan rotativamente a dicha rueda trasera (9);caracterizadas porque el eje (8) de la rueda trasera (9), siendo hueco, está atravesado por un primer eje tractor (11) que se monta en dicho eje hueco (8) através de cojinetes ( 13) y se proyecta fuera del mismo en sendos tramos extremos (11) terminados en las pedaleras (10, 12); uno de estos tramos extremos (11)del primer eje tractor (11), tiene calado una primera rueda dentada conductora (14) la cual, a través de una prime ra cadena (15), acciona a una primera ruedadentada conducida (16) y a una segunda rueda dentada conductora (17), estas ultimas fijadas a un eje comun (18) que trabaja rotativamente sobre un soporte fijo(19); y a su vez, esta segunda rueda dentada con ductora (17), a través de una segunda cadena (15) acciona a una segunda rueda dentada conducida (20) que seencuentra fijada al eje hueco (8) de la rueda trasera (9) del vehículo; teniendo al menos una de estas ruedas dentadas conductoras un diámetro mayor que el delas demás ruedas dentadas (16), (17) y (20) que componen el dispositivo de accionamiento.Improvements in drive devices for bicycles and tricycles in general; of the type in which the application vehicle such as a bicycle comprises a frame (a) which, towards the anterior area of the same vehicle is provided with a command handle (1) fixed to the top of a steering axle (2) the which includes a first fork (3) at whose end (3) the transverse axle (4) of at least one front wheel (5) is rotatably mounted; while towards the rear area, the upper part of said frame (a) has at least one seat (6) fixed, while the lower part forms a second fork (7) in which, transversely and rotatably, it is mounted to the shaft (8) of a rear wheel (9) connected to an apex drive device (b) (12); and this pedal drive device (b) (12) is integrated by two connecting rod arms (10) which, projected in diametraloposed arrangement from the ends (11) of a tractor axle (11), end in two pedals ( 12) with those who rotatably command said rear wheel (9); characterized in that the axle (8) of the rear wheel (9), being hollow, is crossed by a first tractor axle (11) that is mounted on said hollow axle (8) through bearings (13) and projected out of the same in two extreme sections (11) terminated on the pedals (10, 12); one of these end sections (11) of the first tractor axle (11), has a first driving gearwheel (14) which, through a first chain (15), drives a first driven gearwheel (16) already a second driving gearwheel (17), the latter fixed to a common axle (18) that rotatably works on a fixed support (19); and in turn, this second gearwheel with duct (17), through a second chain (15) drives a second driven gearwheel (20) that is fixed to the hollow shaft (8) of the rear wheel (9) of the vehicle; at least one of these conductive sprockets having a diameter greater than that of the other sprockets (16), (17) and (20) that make up the drive device.
