Operating device of speed changer for automobile

Abstract

Abstract PURPOSE:To operate a sub speed changer and switching operations for four wheels with single operating lever by controlling a coupling operation between a shift member and an operating shaft. CONSTITUTION:When an operating lever 72 is shifted to a position FF for a front drive, a synchromesh mechanism 40 for driving rear wheels is not engaged with a gear 38, therefore, rear wheels are not driven, while front wheels are driven at a high-speed range without speed reduction by a sub speed changers. When the operating lever 72 is shifted to a position 4WD4 where four wheels drive in economical running range may be effected, the synchromesh mechanism 40 is shifted to the left and is engaged with the gear 38, therefore, both front and rear wheels are driven at high-speed range with four steps speed change without speed reduction by the sub speed changers. Further, when the lever 72 is shifted to the position 4WDp of a high-output side, a sleeve 41 for the synchromesh mechanism 12 is moved and an engagement between a gear 11 and the synchromesh mechainsm is effected, and thereby, the front and rear wheels are driven at low-speed range with four steps speed change.
