自动变速箱结构紧凑、布局合理且传动效率高。变速箱的壳体为整体式，内部结构包括行星齿轮、阀体、离合器及制动器等。01N型变速器各挡的传动比分别为：1挡2.714，2挡2.551，3挡1.000，4挡0.679。
The automatic transmission has compact structure, reasonable layout and high transmission efficiency. The housing of the gearbox is integral, and the internal structure includes planetary gear, valve body, clutch and brake. The gear ratios of 01N transmission are 2.714 for 1st gear, 2.551 for 2nd gear, 1.000 for 3rd gear and 0.679 for 4th gear.
从理论上讲，变速器的每个挡位又分液压和机械2种状态。由于装备了带有锁止离合器的液力变矩器，TCM可根据车辆的负载、速度和挡位等状况，控制锁止离合器器电磁阀的动作，实现锁止离合器接合与分离，但与变矩器内部打滑无关。当锁止离合器接合时，变速器的前进挡由液力变矩器的打滑方式变为机械直接驱动的方式。
Theoretically speaking, each gear of the transmission can be divided into hydraulic and mechanical states. Due to the hydraulic torque converter equipped with lockup clutch, TCM can control the action of lockup clutch solenoid valve according to the load, speed and gear of the vehicle, so as to realize the engagement and disengagement of lockup clutch, but it has nothing to do with the internal slip of torque converter. When the lockup clutch is engaged, the forward gear of the transmission changes from the slip mode of the hydraulic torque converter to the mechanical direct drive mode.
自动变速箱的机械结构部分主要由1个行星齿轮组、3个离合器、2个制动器及1个单向轮组成。其中行星齿轮组是由1个小太阳齿轮、1个大太阳齿轮、3个短行星齿轮、3个长行星齿轮、行星齿轮架及齿圈组成。
The mechanical structure of automatic transmission is mainly composed of a planetary gear set, three clutches, two brakes and a one-way wheel. The planetary gear set is composed of a small sun gear, a large sun gear, three short planetary gears, three long planetary gears, planetary carrier and ring gear.
变速器在工作时，阀体通过油压控制离合器、制动器的动作，酝瓿梢毫Ρ渚仄骱托行浅萋肿橹涞Υ洹Ｈ绻牒掀鱇1工作，就会驱动小太阳齿轮。离合器K2(图16)则是用来驱动大太阳齿轮的，离合器K3驱动行星齿轮架，制动器B1制动行星齿轮架，动力是通过齿圈输出的。
When the transmission is working, the valve body controls the action of clutch and brake through oil pressure, and the small sun gear will be driven when the clutch and brake are working in the horizontal direction and in the vertical direction. Clutch K2 (FIG. 16) is used to drive the big sun gear, clutch K3 drives the planetary carrier, and brake B1 brakes the planetary carrier. The power is output through the ring gear.
