REVERSE GEAR INTERMEDIATE SHAFT SUPPORTING STRUCTURE OF TRANSMISSION

摘要

A reverse gear intermediate shaft supporting structure of a transmission comprises a transmission housing (100), a partition wall (101) and a boss (Q). The transmission housing (100), the partition wall (101) and the boss (Q) are in an integrated structure; a reverse gear idle wheel installation space (J) is arranged between one side, close to a main box of the transmission, of the partition wall (101) and the boss (Q); the partition wall (101) is provided with a second reverse gear intermediate shaft supporting hole (K2) and an auxiliary box intermediate shaft supporting hole (K) that are non-concentric; one side, close to the transmission housing (100), of the boss (Q) is supported on the transmission housing (100) through several ribs (a) and web plates (b, c) are arranged among the several ribs (a). In the reverse gear intermediate shaft supporting structure of the transmission, multiple ribs (a) are used to support the boss (Q) of the reverse gear intermediate shaft, the boss (Q) of the reverse gear intermediate shaft is cast to the back auxiliary box partition wall (101), and in combination with machining work, a disc milling cutter is used to mill the reverse gear idle wheel space (J).
