方向機總成簡介

轉(zhuan)向(xiang)(xiang)(xiang)機(ji)總成(cheng)即轉(zhuan)向(xiang)(xiang)(xiang)器(qi)，又(you)名轉(zhuan)向(xiang)(xiang)(xiang)機(ji)、方向(xiang)(xiang)(xiang)機(ji)，它是(shi)(shi)轉(zhuan)向(xiang)(xiang)(xiang)系中(zhong)最重要的部件。它的作用是(shi)(shi)：增大(da)轉(zhuan)向(xiang)(xiang)(xiang)盤(pan)傳(chuan)到(dao)轉(zhuan)向(xiang)(xiang)(xiang)傳(chuan)動(dong)機(ji)構(gou)的力(li)(li)和改變力(li)(li)的傳(chuan)遞方向(xiang)(xiang)(xiang)。轉(zhuan)向(xiang)(xiang)(xiang)器(qi)的操縱(zong)(zong)是(shi)(shi)全液壓式(shi)(shi)(shi)，也就是(shi)(shi)說在轉(zhuan)向(xiang)(xiang)(xiang)柱和轉(zhuan)向(xiang)(xiang)(xiang)輪之(zhi)間沒(mei)有機(ji)械(xie)連接，在轉(zhuan)向(xiang)(xiang)(xiang)器(qi)與(yu)轉(zhuan)向(xiang)(xiang)(xiang)油(you)(you)缸之(zhi)間是(shi)(shi)液壓管(guan)或軟管(guan)鏈接。當轉(zhuan)動(dong)方向(xiang)(xiang)(xiang)盤(pan)，轉(zhuan)向(xiang)(xiang)(xiang)器(qi)根(gen)據方向(xiang)(xiang)(xiang)盤(pan)轉(zhuan)動(dong)比例輸送相(xiang)對的油(you)(you)量(liang)，該油(you)(you)量(liang)直接流到(dao)操縱(zong)(zong)缸相(xiang)應一側(ce)，同時另一側(ce)的油(you)(you)量(liang)回到(dao)油(you)(you)箱。轉(zhuan)向(xiang)(xiang)(xiang)器(qi)按結構(gou)形(xing)式(shi)(shi)(shi)可分為(wei)(wei)：有齒(chi)輪齒(chi)條(tiao)式(shi)(shi)(shi)轉(zhuan)向(xiang)(xiang)(xiang)器(qi)、蝸桿曲柄指(zhi)(zhi)銷(xiao)式(shi)(shi)(shi)轉(zhuan)向(xiang)(xiang)(xiang)器(qi)、循環(huan)球-齒(chi)條(tiao)齒(chi)扇式(shi)(shi)(shi)轉(zhuan)向(xiang)(xiang)(xiang)器(qi)、循環(huan)球曲柄指(zhi)(zhi)銷(xiao)式(shi)(shi)(shi)轉(zhuan)向(xiang)(xiang)(xiang)器(qi)、蝸桿滾輪式(shi)(shi)(shi)轉(zhuan)向(xiang)(xiang)(xiang)器(qi)等(deng)。按照助(zhu)力(li)(li)形(xing)式(shi)(shi)(shi)又(you)可以分：為(wei)(wei)機(ji)械(xie)式(shi)(shi)(shi)（無助(zhu)力(li)(li)）轉(zhuan)向(xiang)(xiang)(xiang)器(qi)，和動(dong)力(li)(li)式(shi)(shi)(shi)（有助(zhu)力(li)(li)）轉(zhuan)向(xiang)(xiang)(xiang)器(qi)兩(liang)種(zhong)，其中(zhong)動(dong)力(li)(li)轉(zhuan)向(xiang)(xiang)(xiang)器(qi)又(you)可以分為(wei)(wei)氣壓動(dong)力(li)(li)式(shi)(shi)(shi)、液壓動(dong)力(li)(li)式(shi)(shi)(shi)、電動(dong)助(zhu)力(li)(li)式(shi)(shi)(shi)、電液助(zhu)力(li)(li)式(shi)(shi)(shi)等(deng)種(zhong)類。
