文档介绍：摘要
随着当今经济的快速发展,轿车越来越普遍的作为普通的消费品进入百姓家庭。人们在追求享受的同时也越来越在乎汽车的使用经济性和驾驶的简便性,于是自动变速器在轿车中应运而生,满足了人们对汽车的舒适性和驾驶的简便性。
汽车自动变速器包括有级变速器和无级变速器(CVT)两种。菲亚特轿车装配的是自动无级变速器(CVT),该变速器与前置前驱发动机相匹配输出更强劲的动力。无级变速器主要有以下:液力变矩器、油泵、锁止离合器、无级变速器的传动机构、驻车锁止机构、主减速器和差速器、前进档离合器和倒档制动器、开/关电磁阀、伺服电磁阀、活动控制阀、离合器压力阀、开关阀、手动阀、倒档信号阀等组成。

With the rapid development of economy, cars more and more popular as ordinary consumer goods into people family . People in the pursuit of enjoy and at the same time getting care about car usage economy and driving the simplicity of automatic transmission, then came into being in the car to meet people for the automobile fort and convenience.
Auto automatic transmission include variable transmission and variator (CVT) two car assembly is automatic variator (CVT), the transmission is matched with lead precursor engine output stronger basically has the following: oil pump, the lock of the clutch and variator in vehicle transmission mechanism, the institution, the Lord reducer and differential, forward gears clutch and reversing brakes, open/close ic valve, ic valve, activity servo valves, clutch pressure valves, switch valve, manual valve, reverse gear signal outlet valve, etc.
Keywords: Hydraulic torque converter pump differential Lock up the clutch
