　　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(ji)械領域，涉及推土機(ji)的(de)(de)(de)(de)轉(zhuan)向(xiang)(xiang)離合總成。其發明特點是轉(zhuan)向(xiang)(xiang)離合器(qi)(qi)(qi)主(zhu)動片(pian)(pian)(pian)與(yu)摩(mo)擦(ca)(ca)(ca)片(pian)(pian)(pian)的(de)(de)(de)(de)壓(ya)緊采用(yong)碟形彈(dan)簧壓(ya)緊，結構緊湊，壓(ya)盤受力面積大(da)，受力均勻，轉(zhuan)向(xiang)(xiang)較平穩。中央傳(chuan)動軸(zhou)(zhou)的(de)(de)(de)(de)大(da)螺旋(xuan)傘齒(chi)輪(lun)為(wei)零度(du)弧齒(chi)錐齒(chi)輪(lun)，降(jiang)低了傳(chuan)動軸(zhou)(zhou)的(de)(de)(de)(de)軸(zhou)(zhou)向(xiang)(xiang)力。進行轉(zhuan)向(xiang)(xiang)操縱(zong)時，采用(yong)液壓(ya)分(fen)離，輕松省(sheng)力。轉(zhuan)向(xiang)(xiang)離合器(qi)(qi)(qi)半(ban)浸在(zai)油(you)(you)(you)(you)中，為(wei)濕式，潤(run)(run)滑油(you)(you)(you)(you)經過接盤的(de)(de)(de)(de)豎向(xiang)(xiang)油(you)(you)(you)(you)道(dao)以及錐齒(chi)輪(lun)軸(zhou)(zhou)內部的(de)(de)(de)(de)油(you)(you)(you)(you)道(dao)，強制(zhi)潤(run)(run)滑轉(zhuan)向(xiang)(xiang)離合器(qi)(qi)(qi)的(de)(de)(de)(de)主(zhu)動片(pian)(pian)(pian)與(yu)摩(mo)擦(ca)(ca)(ca)片(pian)(pian)(pian)，摩(mo)擦(ca)(ca)(ca)片(pian)(pian)(pian)上(shang)(shang)有很(hen)多圓周(zhou)向(xiang)(xiang)及徑向(xiang)(xiang)油(you)(you)(you)(you)道(dao)，使得主(zhu)動片(pian)(pian)(pian)與(yu)摩(mo)擦(ca)(ca)(ca)片(pian)(pian)(pian)表面上(shang)(shang)形成壓(ya)力油(you)(you)(you)(you)膜，并且(qie)通(tong)過油(you)(you)(you)(you)液的(de)(de)(de)(de)流動，帶走部分(fen)熱量。同時，制(zhi)動鼓的(de)(de)(de)(de)表面上(shang)(shang)有很(hen)多排(pai)油(you)(you)(you)(you)孔(kong)，主(zhu)動片(pian)(pian)(pian)和摩(mo)擦(ca)(ca)(ca)片(pian)(pian)(pian)之間擠(ji)出的(de)(de)(de)(de)潤(run)(run)滑油(you)(you)(you)(you)經過排(pai)油(you)(you)(you)(you)孔(kong)排(pai)掉，從而(er)延長轉(zhuan)向(xiang)(xiang)離合器(qi)(qi)(qi)的(de)(de)(de)(de)使用(yong)壽命。
