Abstract:
A transmission comprising:a casing; an input shaft substantially vertically supported by the casing; first and second intermediate shafts substantially horizontally supported by the casing; a pair of axles substantially horizontally supported by the casing and extending from the casing in opposite directions; a gear train for transmitting the rotation of the input shaft to the first intermediate shaft; a friction clutch supported on the first intermediate shaft; a driving speed-change gear train rotatably supported on the first intermediate shaft; a driven speed-change gear train rotatably supported on the second intermediate shaft and meshing with the driving speed-change gear train; a shifter supported axially slidably on the second intermediate shaft non-rotatably relative thereto, wherein the shifter meshes one gear of the driven gear train with the second intermediate shaft in accordance with its axial position; an output gear provided or integrally formed on the second intermediate shaft non-rotatably relative thereto; and a differential gear meshing with the output shaft and transmitting drive power from the output shaft to the pair of axles, the friction clutch including: a driving friction member having a conical friction surface and supported on the first intermediate shaft in a non-rotatable and axially slidable manner; a driven friction member having a friction surface corresponding to the conical friction surface, rotatably supported on the first intermediate shaft and coupled with the driving gear train; and a clutch arm for sliding the driving friction member for engagement with the driven friction member.
