變速箱倒車鎖的作用是什么

　　【太平洋汽車網(wǎng)】變速箱倒車鎖的作用是提醒，使駕駛員必須對變速桿施加較大的力，才能掛入倒檔，起到提醒作用，防止誤掛倒檔，提高安全性。

　　首發(fā)于汽車英語無障礙寫文章登錄/注冊3.1 Introduction3.1.1 Mechanical Design of the Gearbox 變速箱的機(jī)械結(jié)構(gòu)The mechanical power transmission of the gearbox has been optimized with regard to gearshift comfort， fuel consumption reduction and product quality.變速箱機(jī)械傳動裝置在換擋便捷性、降低油耗和產(chǎn)品質(zhì)量方面進(jìn)行了優(yōu)化。

　　Figure 3-1 shows the mechanical design of the gearbox.變速箱的機(jī)械結(jié)構(gòu)如圖3-1所示。

　　The torque developed by the engine is transferred to the gearbox via a converter with a controlled converter lockup clutch. The gears are shifted by means of muli-disc（多片式） clutches. The six forward gears， used in automatic gearboxes， and the reverse gear are produced by a planetary gear train（行星齒輪組）.發(fā)動機(jī)輸出的扭矩通過帶自調(diào)節(jié)變矩器離合器的變矩器傳遞到變速器。換擋通過多片式離合器實現(xiàn)。自動變速箱中使用的6個前進(jìn)擋和倒車檔由行星齒輪組產(chǎn)生。
