Abstract

PURPOSE:To contrive to shorten the total length of the transmission and facilitate the layout of the transmission to the car body by a structure wherein an input shaft, an output shaft and a counter shaft are arranged parallel to each other and forward gears are dispersedly provided onto the input shaft and output shaft. CONSTITUTION:The input shaft 2, the output shaft 3 and the counter shaft 4 are arranged parallel to each other. Driven gears 12 and 13, which are made integral with the output shaft 3, are engaged with the forward gears 9, 10, 14 and 15, which are located on a tubular shaft 7 and the counter shaft 4. An idler gear 17, which is loosely fit with an output shaft 3, is engaged with a counter-driven gear 18, which is made integral with the drive gear 5 and the counter shaft 4.

No. 1 and Japanese Unexamined Patent Publication No. 127842/1984, someday, the forward gear (usually 4) will be installed in the axial direction of the input shaft.
Because the ST+M gear) is installed, the overall length of the transmission is relatively long, and it is a step up to the car body. VC problems rarely occur.

In particular, when five types of forward gears are arranged on the in-foot shaft, the total length of the transmission becomes large. It is an object of the present invention to provide a unidirectional transmission which can have a short block edge and which allows easy layout of the transmission with respect to a vehicle body.

In order to achieve the above-mentioned objects, the present invention provides a counter shaft in addition to the conventional input shaft and out shaft, and forward gears are arranged in a distributed manner on the fN input V shaft and the counter shaft, This is a book that allows you to obtain the same speed ability as the conventional one.
