自動(dòng)變速箱結(jié)構(gòu)緊湊、布局合理且傳動(dòng)效率高。變速箱的殼體為整體式，內(nèi)部結(jié)構(gòu)包括行星齒輪、閥體、離合器及制動(dòng)器等。01N型變速器各擋的傳動(dòng)比分別為：1擋2.714，2擋2.551，3擋1.000，4擋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.

從理論上講，變速器的每個(gè)擋位又分液壓和機(jī)械2種狀態(tài)。由于裝備了帶有鎖止離合器的液力變矩器，TCM可根據(jù)車輛的負(fù)載、速度和擋位等狀況，控制鎖止離合器器電磁閥的動(dòng)作，實(shí)現(xiàn)鎖止離合器接合與分離，但與變矩器內(nèi)部打滑無關(guān)。當(dāng)鎖止離合器接合時(shí)，變速器的前進(jìn)擋由液力變矩器的打滑方式變?yōu)闄C(jī)械直接驅(qū)動(dòng)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.

自動(dòng)變速箱的機(jī)械結(jié)構(gòu)部分主要由1個(gè)行星齒輪組、3個(gè)離合器、2個(gè)制動(dòng)器及1個(gè)單向輪組成。其中行星齒輪組是由1個(gè)小太陽齒輪、1個(gè)大太陽齒輪、3個(gè)短行星齒輪、3個(gè)長(zhǎng)行星齒輪、行星齒輪架及齒圈組成。

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.

變速器在工作時(shí)，閥體通過油壓控制離合器、制動(dòng)器的動(dòng)作，醞瓿梢毫Ρ渚仄骱托行淺萋腫櫓淶畝Υ洹Ｈ綣牒掀鱇1工作，就會(huì)驅(qū)動(dòng)小太陽齒輪。離合器K2(圖16)則是用來驅(qū)動(dòng)大太陽齒輪的，離合器K3驅(qū)動(dòng)行星齒輪架，制動(dòng)器B1制動(dòng)行星齒輪架，動(dòng)力是通過齒圈輸出的。

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.
