<p>A transmission for a tractor comprising:
an input shaft (100) receiving power from an engine;
an idle shaft (200) disposed parallel with the input shaft (100);
an output shaft (300) disposed parallel with the idle shaft (200);
a forward driving gear (110) and a reverse driving gear (120) installed on the input shaft (100) so as to rotate idle;
a forward driven gear (210) installed on the idle shaft (200) and engaged with the forward driving gear (110);
a reverse driven gear (220) installed on the idle shaft (200) and engaged by way of an idle gear (220a) with the driving gear (120);
a high speed driving gear (230) and a low speed driving gear (240) installed axially between the forward driven gear (210) and the reverse driven gear (220) so as to rotate idle;
and
high speed/low speed driven gears (310 and 320) installed on the output shaft (300) and engaged with the high speed driving gear (230) and the low speed driving gear (240) respectively, characterized in that the output shaft (300) transmitting power to a main transmission part; and in that the transmission comprises
a forward/reverse clutch (501) installed between the forward driving gear (110)
and the reverse driving gear (120) to selectively connect the forward driving gear (110) or the reverse driving gear (120) to the input shaft (100);
and
a high speed/low speed clutch (502) installed axially between the high speed driving gear (230) and the low speed driving gear (240) to selectively connect the high speed driving gear (230) or the low speed driving gear (240) to the idle shaft (200).</p> |
