液力變矩器簡介

液(ye)(ye)力變(bian)(bian)矩(ju)(ju)器(qi)(qi)：液(ye)(ye)力變(bian)(bian)矩(ju)(ju)器(qi)(qi)的(de)工(gong)(gong)作(zuo)原理是：泵(beng)輪由(you)(you)發(fa)動(dong)機驅動(dong)旋轉(zhuan)(zhuan)，推動(dong)液(ye)(ye)體(ti)隨泵(beng)輪一起(qi)繞其(qi)軸線旋轉(zhuan)(zhuan)，使其(qi)獲得(de)一定的(de)速度和(he)壓(ya)力。液(ye)(ye)力變(bian)(bian)矩(ju)(ju)器(qi)(qi)由(you)(you)泵(beng)輪、渦輪和(he)導輪組成，其(qi)安(an)裝在發(fa)動(dong)機和(he)變(bian)(bian)速器(qi)(qi)之間(jian)，以液(ye)(ye)壓(ya)油為(wei)工(gong)(gong)作(zuo)介質，起(qi)到傳遞轉(zhuan)(zhuan)矩(ju)(ju)、變(bian)(bian)矩(ju)(ju)、變(bian)(bian)速及(ji)離合的(de)作(zuo)用。

液(ye)力變矩器(qi)的特點是(shi)：

1、根據機器(qi)的行駛阻力(li)或(huo)作(zuo)業(ye)阻力(li)，變矩器(qi)可在一定范圍(wei)內自動地、無級地變速和變矩；

2、延長了(le)機器的(de)使用壽(shou)命；

3、提高了機(ji)器的(de)通(tong)過(guo)性能和舒(shu)適性。

液力變矩器的作用：

液力變矩器的作用：

1、傳遞轉矩：發動機的(de)轉矩通(tong)過(guo)液力變(bian)矩器(qi)的(de)主動元(yuan)件，再通(tong)過(guo)ATF傳給液力變(bian)矩器(qi)的(de)從動元(yuan)件，最后傳給變(bian)速器(qi)；

2、無(wu)級(ji)變速：液(ye)力(li)變矩(ju)器可以(yi)在一(yi)定(ding)范圍(wei)內實現(xian)轉速和轉矩(ju)的無(wu)級(ji)變化；

3、自動(dong)(dong)(dong)(dong)離合：液力變(bian)矩器(qi)由于采用(yong)ATF傳遞動(dong)(dong)(dong)(dong)力，當(dang)踩下制動(dong)(dong)(dong)(dong)踏板(ban)時，發動(dong)(dong)(dong)(dong)機也不會熄火，此(ci)時相當(dang)于離合器(qi)分離。液力變(bian)矩器(qi)是液力傳動(dong)(dong)(dong)(dong)部件的一種(zhong)，由泵輪(lun)、渦(wo)輪(lun)和導向輪(lun)組成。泵輪(lun)同(tong)主動(dong)(dong)(dong)(dong)軸(zhou)(zhou)相連，能(neng)(neng)把主動(dong)(dong)(dong)(dong)軸(zhou)(zhou)輸入(ru)的機械能(neng)(neng)依靠離心力的作用(yong)轉換成液體(ti)(ti)的動(dong)(dong)(dong)(dong)能(neng)(neng)和壓(ya)頭，供渦(wo)輪(lun)做功之用(yong)。渦(wo)輪(lun)和從(cong)動(dong)(dong)(dong)(dong)軸(zhou)(zhou)相連，能(neng)(neng)把液體(ti)(ti)的動(dong)(dong)(dong)(dong)能(neng)(neng)和壓(ya)頭所含的能(neng)(neng)量由從(cong)動(dong)(dong)(dong)(dong)軸(zhou)(zhou)輸出。
