日前，由新興際華集團天津移山公司研制的一種履帶式推土機的轉向離合器總成獲國家發明專利。該專利的優勢，延長了轉向離合器的使用壽命、減輕震動并能夠降低噪音。
該專利屬(shu)于工程機械領域，涉及(ji)推土機的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)向(xiang)離(li)合(he)總(zong)成(cheng)。其發明特點是轉(zhuan)(zhuan)向(xiang)離(li)合(he)器(qi)(qi)主(zhu)動(dong)(dong)(dong)(dong)片(pian)(pian)(pian)與摩擦(ca)片(pian)(pian)(pian)的(de)(de)(de)(de)(de)壓(ya)緊(jin)采(cai)用碟形彈(dan)簧(huang)壓(ya)緊(jin)，結構緊(jin)湊，壓(ya)盤受(shou)力(li)面積大(da)，受(shou)力(li)均勻，轉(zhuan)(zhuan)向(xiang)較平穩。中央傳動(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)大(da)螺旋(xuan)傘齒(chi)(chi)輪(lun)為零度(du)弧齒(chi)(chi)錐齒(chi)(chi)輪(lun)，降低了傳動(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)軸(zhou)(zhou)(zhou)向(xiang)力(li)。進行(xing)轉(zhuan)(zhuan)向(xiang)操縱(zong)時(shi)，采(cai)用液(ye)壓(ya)分(fen)(fen)離(li)，輕松省(sheng)力(li)。轉(zhuan)(zhuan)向(xiang)離(li)合(he)器(qi)(qi)半浸在油(you)(you)中，為濕(shi)式，潤滑油(you)(you)經(jing)過(guo)接盤的(de)(de)(de)(de)(de)豎向(xiang)油(you)(you)道(dao)(dao)以及(ji)錐齒(chi)(chi)輪(lun)軸(zhou)(zhou)(zhou)內(nei)部的(de)(de)(de)(de)(de)油(you)(you)道(dao)(dao)，強制潤滑轉(zhuan)(zhuan)向(xiang)離(li)合(he)器(qi)(qi)的(de)(de)(de)(de)(de)主(zhu)動(dong)(dong)(dong)(dong)片(pian)(pian)(pian)與摩擦(ca)片(pian)(pian)(pian)，摩擦(ca)片(pian)(pian)(pian)上(shang)有(you)很多圓周向(xiang)及(ji)徑向(xiang)油(you)(you)道(dao)(dao)，使得(de)主(zhu)動(dong)(dong)(dong)(dong)片(pian)(pian)(pian)與摩擦(ca)片(pian)(pian)(pian)表面上(shang)形成(cheng)壓(ya)力(li)油(you)(you)膜，并(bing)且通過(guo)油(you)(you)液(ye)的(de)(de)(de)(de)(de)流(liu)動(dong)(dong)(dong)(dong)，帶(dai)走部分(fen)(fen)熱量。同時(shi)，制動(dong)(dong)(dong)(dong)鼓的(de)(de)(de)(de)(de)表面上(shang)有(you)很多排油(you)(you)孔，主(zhu)動(dong)(dong)(dong)(dong)片(pian)(pian)(pian)和摩擦(ca)片(pian)(pian)(pian)之間擠(ji)出的(de)(de)(de)(de)(de)潤滑油(you)(you)經(jing)過(guo)排油(you)(you)孔排掉(diao)，從而(er)延長轉(zhuan)(zhuan)向(xiang)離(li)合(he)器(qi)(qi)的(de)(de)(de)(de)(de)使用壽命。
