Abstract
The invention discloses a four-gear / five-gear automobile transmission. The transmission comprises a transmission shell, a first shaft, a second shaft, an intermediate shaft and a reverse gear intermediate shaft, wherein the first shaft, the second shaft, the intermediate shaft and the reverse gear intermediate shaft are arranged inside the transmission shell, the first shaft extends into the front end of the transmission shell, and a first shaft gear is arranged at the tail end of the transmission shell and is connected to the front end of the second shaft. A five-gear gear pair is arranged in an independent cavity defined by a middle connecting plate and a rear shell, is independent from a main transmission box and can serve as a five-gear transmission or a four-gear transmission for production according to the requirements of users. When the five-gear transmission is needed, a five-gear gear pair and a five-gear synchronizer are arranged inside the rear shell, and therefore the transmission becomes the five-gear transmission; and when the four-gear transmission is needed, the five-gear gear pair and the five-gear synchronizer are removed, a five-gear shifting fork shaft and a five-gear shifting fork are also removed in a control mechanism, and therefore the transmission becomes the four-gear transmission. According to the four-gear / five-gear automobile transmission, conversion of the four-gear transmission and the five-gear transmission and universalization of parts can be realized.
Description
【Technical field】
The invention belongs to automotive transmission field, is related to a kind of four and keeps off/five gear automobile speed changers.
