Vehicle transmission assembly

A vehicle transmission assembly comprising:

• a transmission casing;
• a drive shaft which is disposed within said transmission casing at a high level and extends axially of said casing, said drive shaft extending forwardly and rearwardly from said transmission casing;
• a speed-change shaft which is disposed within said transmission casing at a low level and extends axially of said casing, said speed-change shaft extending rearwardly from said transmission casing;
• an intermediate shaft which is disposed within said transmission casing at an intermediate level between said drive shaft and said speed-change shaft and which extends axially of said casing, said intermediate shaft being located aside in a direction across said transmission casing;
• a clutch which is disposed on said drive shaft at an axial mid portion of said drive shaft;
• a hollow shaft which is rotatably mounted on said drive shaft at one axial side of said clutch such that said hollow shaft is driven to rotate by said drive shaft through said clutch;
• a first mechanical speed-change mechanism which is disposed between said hollow shaft and said intermediate shaft and comprises plural speed-change gear trains including plural driving gears mounted on said hollow shaft and plural driven gears mounted on said intermediate shaft, said intermediate shaft being driven to rotate exclusively by said hollow shaft through said first mechanical speed-change mechanism;
• and
• a second mechanical speed-change mechanism which is disposed between said intermediate shaft and said speed-change shaft at a location axially apart from said first speed-change mechanism and comprises plural speed-change gear trains including plural driving gears mounted on said intermediate shaft and plural driven gears mounted on said speed-change shaft, said speed-change shaft being driven to rotate exclusively by said intermediate shaft through said second mechanical speed-change mechanism.
