變速箱倒車鎖的作用是什么

　　【太平洋汽車網】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 變速箱的機械結構The mechanical power transmission of the gearbox has been optimized with regard to gearshift comfort， fuel consumption reduction and product quality.變速箱機械傳動裝置在換擋便捷性、降低油耗和產品質量方面進行了優化。

　　Figure 3-1 shows the mechanical design of the gearbox.變速箱的機械結構如圖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）.發動機輸出的扭矩通過帶自調節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。自動變速箱中使用的6個前進擋和倒車檔由行星齒輪組產生。
