Abstract

UN SISTEMA DE CAMBIO TRASERO PARA PIÑONES DE BICICLETA, EL CUAL COMPRENDE UN CUERPO SUPERIOR (5) QUE PUEDE FIJARSE AL CUADRO DE LA BICICLETA Y UN CUERPO INFERIOR QUE LLEVA LOS ELEMENTOS DE TRANSMISION PARA LA CADENA, EL CUAL PUEDE MOVERSE CON RESPECTO AL CUERPO SUPERIOR A FIN DE PODER ACOPLAR SELECTIVAMENTE LA CADENA CON UNA SERIE DE PIÑONES MONTADOS EN EL CUBO DE LA RUEDA POSTERIOR DE LA BICICLETA. EL CUERPO INFERIOR (11) VA UNIDO MEDIANTE UNA JUNTA ARTICULADA EN FORMA DE PARALELOGRAMO A UN ELEMENTO INTERMEDIO DE CONEXION (9) QUE A SU VEZ VA MONTADO DE MANERA QUE PUEDE DESLIZARSE SOBRE UNA GUIA (8) MONTADA EN EL CUERPO SUPERIOR (5). SE HAN PREVISTO MEDIOS (26) PARA CORRELACIONAR UNIVOCAMENTE LOS MOVIMIENTOS DEL ELEMENTO INTERMEDIO (9) RESPECTO AL CUERPO SUPERIOR (5) CON LOS MOVIMIENTOS DEL CUERPO INFERIOR (11) RESPECTO AL ELEMENTO INTERMEDIO (9). DE ESTE MODO, EL MOVIMIENTO RESULTANTE DEL CUERPO INFERIOR CON RELACION AL CUERPO SUPERIOR TIENE TANTO UNA COMPONENTE A LO LARGO DEL EJE (25) DELCUBO DE LA RUEDA POSTERIOR DE LA BICICLETA, COMO UNA COMPONENTE RADIAL A DICHO EJE (25).
