Title:
VEHICLE MANUAL TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2015/079838
Kind Code:
A1
Abstract:
A vehicle manual transmission in which two "combined drive gears" consisting of a "drive gear (G23i) for combining the second and third drive gears" and a "drive gear (G57i) for combining the fifth and seventh drive gears" are positioned on an input shaft (A1). In order, starting from one side in the axial direction, a first intermediate shaft (A3) has the following positioned thereon: a first final drive gear (Gfi1), a first-speed driven gear (G1o), a reverse driven gear (GRi) for integrally rotating with a second-speed driven gear (G2o, G2o), a sixth-speed driven gear (G6o), and a fifth-speed driven gear (G5o). Meanwhile, a second intermediate shaft has the following positioned thereon, in order, starting from one side in the axial direction: a second final drive gear (Gfi2), a fourth-speed driven gear (G4o), a third-speed driven gear (G3o), a reverse driven gear (GRo), and a seventh-speed driven gear (G7o). As a result, it is possible to obtain a "seven-speed M/T having one gear to be used for reverse," not provided with an idler shaft, and provided with an input shaft, an output shaft, and first and second intermediate shafts, wherein the total M/T length is short, and it is possible to widen the range of the speed reduction ratio.
