Filed: 1989-12-28
Abstract: PURPOSE:To unnecessitate reversing power transmitting mechanism in a travel transmission device for a construction machine by providing a driving shaft, having side clutch mechanism fitted thereto, with variable torque power driving clutch mechanism, placed in the clutch-on state being interlocked with the clutch- off state of the side clutch mechanism, separately in the reversible state. CONSTITUTION:In case of, for instance, stepping on a right-side operating pedal to disengage the engagement between a clutch gear 35a and a clutch 36a for turning, clutch plates 38, 39 in the semi-clutch state are not pressed sufficiently, so that a driving side sprocket 7a on the turning side stops and is turned slowly. When a pedal 54a is stepped on sufficiently, the clutch plates 38, 39 are pressed to be in the clutch-on state. Power is thereby transmitted to reversing mechanism A from a gear 42 integrally provided at a driving shaft 31 through a counter gear 44 and gears 45, 45a, so that the body case 33a of a multiple disc clutch 32a is rotated in the reverse direction to the driving shaft 31 to perform rapid turning. With this constitution, the structure is simplified.
