Abstract
A supporting structure for a reverse countershaft of a transmission includes a transmission case, a partition wall and a boss, wherein the transmission case, the partition wall and the boss are formed integrally; a reverse idler gear installation space is provided between a side, close to a transmission main case, of the partition wall and the boss; and the partition wall is provided with a second reverse countershaft supporting hole and an auxiliary case countershaft supporting hole which are not concentric. In supporting structure for the reverse countershaft of the transmission, multiple ribs are used to support the boss of the reverse countershaft, the boss of the reverse intermediate shaft is cast until reaching the rear auxiliary case partition wall, and in combination with machining work, the reverse idle wheel space is milled by a disc milling cutter.
