Abstract

UNA SUSPENSION RETRAIBLE (10) QUE COMPRENDE UN BRAZO TRASERO (22) MONTADO PIVOTALMENTE AL CHASIS DEL VEHICULO (12) UN AMORTIGUADOR DE AIRE CON RESORTE (30) MONTADO ENTRE EL BRAZO TRASERO Y EL CHASIS, UN DISPOSITIVO ELEVADOR (32) MONTADO ENTRE EL BRAZO TRASERO Y EL CHASIS. EL DISPOSITIVO ELEVADOR (32) COMPRENDE UNA BIELA (60) MONTADA PIVOTALMENTE ENTRE EL MARCO (12) Y EL BRAZO DE PALANCA (64) QUE ESTA MONTADO DE FORMA FIJA AL BRAZO TRASERO (22). LA BIELA (60) APLICA UNA FUERZA AL BRAZO DE PALANCA (64) QUE APLICA UN MOMENTO AL BRAZO TRASERO (22) PARA FORZAR EL BRAZO TRASERO Y LAS RUEDAS UNIDAS AL MISMO (14) A UNA POSICION RETRAIDA. LA FUERZA DEL AMORTIGUADOR DE AIRE CON RESORTE (30) PUEDE AJUSTARSE PARA QUE CONTRARRESTE EL MOVIMIENTO HACIA ARRIBA DE LAS RUEDAS (14).A RETRAIBLE SUSPENSION (10) INCLUDING A REAR ARM (22) PIVOTALLY MOUNTED TO THE VEHICLE CHASSIS (12) A SPRING AIR SHOCK (30) MOUNTED BETWEEN THE REAR ARM AND THE CHASSIS, A LIFTING DEVICE (32) REAR ARM AND CHASSIS. THE LIFTING DEVICE (32) INCLUDES A CONNECTING ROD (60) PIVOTALLY MOUNTED BETWEEN THE FRAME (12) AND THE LEVER ARM (64) WHICH IS FIXELY MOUNTED TO THE REAR ARM (22). THE CONNECTING ROD (60) APPLIES A FORCE TO THE LEVER ARM (64) THAT APPLIES A MOMENT TO THE REAR ARM (22) TO FORCE THE REAR ARM AND THE WHEELS ATTACHED TO IT (14) TO A RETRACTED POSITION. THE STRENGTH OF THE SPRING AIR SHOCK (30) CAN BE ADJUSTED TO COUNTER THE MOVEMENT UPWARD THE WHEELS (14).
