Abstract

LA DIRECCION ASISTIDA A BASE DE PIÑON Y CREMALLERA DESCRITA, QUE ES DIRIGIDA DE FORMA PARTICULAR PARA VEHICULOS A MOTOR PESADOS, DISPONE DE DOS CIRCUITOS DE CONTROL SEPARADOS HIDRAULICAMENTE. SE DISPONE DE UN ENGRANAJE (2) DE PIÑON MONTADO EN UNA CARCASA (1) PARA MOVIMIENTO ROTACIONAL Y MONTADO EN LA MISMA CARCASA PARA MOVIMIENTO TRANSACCIONALES ENCUENTRA UNA CREMALLERA (3). LA CREMALLERA (3) ENGRANA CON EL PIÑON (2). CADA UNO DE LOS DOS CIRCUITOS DE CONTROL INCLUYE UNA UNIDAD (5,13) PISTON Y CILINDRO, LAS DOS UNIDADES ESTAN CONECTADAS UNA CON OTRA DE FORMA MECANICA Y DISPUESTAS PARALELAS UNA A OTRA. EL CILINDRO (6) DE LA PRIMERA UNIDAD (5) PISTON Y CILINDRO FORMA UNA EXTENSION DE LA CARCASA (1), Y LA CARCASA CONJUNTAMENTE CON LA PRIMERA UNIDAD CILINDRO Y PISTON Y UN APOYO (9) CILINDRICO SE PROYECTAN EN EL INTERIOR DE UNA CARCASA (12) PRINCIPAL. EL CILINDRO (14) DE LA SEGUNDA UNIDAD (13) PISTON Y CILINDRO ESTA AJUSTADO EN LA CARCASA (12) PRINCIPAL. EL VASTAGO (4,16) DE PISTON DE LAS DOS UNIDADES PISTON Y CILINDRO ESTAN CONECTADOS UNO CON OTROS POR MEDIO DE UNA HORQUILLA (20).
