Description
Technical field
The utility model relates to the miniature walking tractor gearbox.
Background technique
At present, the miniature walking tractor on the market, what have is the scaled of middle low power hand tractor, not enough light and flexible during operation; What have does not have a steering equipment, turns to difficulty, and steering force is big.Though Chinese patent 02264228.5 disclosed miniature walking tractor gearbox can solve and turn to difficult problem, but, exist steering gear in conjunction with separation difficulty in the use, handling maneuver power is big, turn to heavily, steering gear and turn to spring easy to wear, problem such as steering equipment working life is short.
Summary of the invention
The purpose of this utility model is: a kind of traction is provided, drives and have both, turn to a kind of flexibly miniature walking tractor gearbox.
The utility model improvement on above-mentioned miniature walking tractor gearbox basis obtains, and concrete improvement design proposal is as follows:
A kind of miniature walking tractor gearbox, comprise casing, the parallel six roots of sensation gear shaft that is provided with in the casing also comprises 16 gears being located at respectively on the gear shaft, go back correspondence in the casing and be provided with a pair of shift fork, it is characterized in that: the 3rd 7 that from top to bottom is arranged in parallel is provided with disjunctor gear 6 and 8; The 4th 11 is steering shaft, and the steering shaft middle part is provided with gear 9, both sides and is arranged with gear 10 and spring respectively; Gear 9 meshes with the inboard gear of disjunctor gear 8; A pair of shift fork 12 and two gears, 10 corresponding being located in the casing; The gearwheel that both sides are arranged with disjunctor gear 13, two disjunctor gears 13 relative sides respectively on the 5th 14 respectively with steering shaft on gear 10 engagements; The small gear of two disjunctor gears, 13 opposing sides respectively with the 6th 15 on 17 engagements of a pair of gear.
Useful technique effect of the present utility model is:
1, the utility model handling maneuver power is little, and steering gear 10 is easy in conjunction with separating with gear 9 when turning to, and has guaranteed to turn to light and flexible.
2, by architecture advances, steering gear and turn to spring stress less; Thereby, improved working life of steering equipment.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
This miniature walking tractor gearbox comprises casing 18, the parallel six roots of sensation gear shaft that is installed with in the casing 18, promptly the axle 1, the axle 4, the axle 7, the axle 11, the axle 14 and the axle 15, also comprise 16 gears that are loaded on respectively on the gear shaft, go back correspondence in the casing 18 a pair of shift fork is installed, referring to Fig. 1, Fig. 2.
By lining disjunctor gear 2 be installed on the axle 1 that is arranged in parallel from top to bottom, axle 1 two end supports is on casing 18;
Axle 4 middle parts are splined shaft, disjunctor gear 3 and gear 5 suits thereon, shaft end has spline, and axle 4 right-hand members extend casing 18 outsides, as output terminal, on the casing 18 of axle 4 by bearing supporting;
Be installed with disjunctor gear 6 and 8 by key on the axle 7; Axle 7 two ends are bearing on the casing 18 by bearing;
Axle 11 is a steering shaft, and the steering shaft middle part is installed with gear 9, both sides are respectively installed with gear 10 and spring; Gear 9 meshes with the inboard gear of disjunctor gear 8; A pair of shift fork 12 and two gears, 10 corresponding being installed in the casing 18;
The gearwheel that both sides are respectively installed with disjunctor gear 13, two disjunctor gears 13 relative sides on the axle 14 respectively with steering shaft on gear 10 engagements; The small gear of two disjunctor gears, 13 opposing sides respectively with the 6th 15 on 17 engagements of a pair of gear;
Axle 15 1 ends are splined shaft, and gear 17 is housed on splined shaft, axle 15 by bearing support 16 and Bearing Installation on casing 18.
Working procedure is as follows:
Power is by axle 4 input, when by disjunctor gear 3 respectively with disjunctor gear 6 respectively in conjunction with the time, realize the height, the mid ranger that advance; When gear 5 combines with disjunctor gear 8, realize the bottom gear that advances; When gear 5 combines with disjunctor gear 2, realize reverse gear, thereby finish four kinds of rotating speeds of power output.When steering equipment works, axle 11 the right and left output speed similarities and differences, thus realize turning to function.
Specifically, during top gear, power is imported by axle 4, through disjunctor gear 3 and disjunctor gear 6, and again through disjunctor gear 8, gear 9, gear 10, disjunctor gear 13, gear 17, final power input shaft 15, the driving device running realizes several work.During mid ranger, power is imported by axle 4, through disjunctor gear 3 and disjunctor gear 6, and again through disjunctor gear 8, gear 9, gear 10, disjunctor gear 13, gear 17, final power input shaft 15, the driving device running realizes several work.During bottom gear, power is imported by axle 4, through gear 5 and disjunctor gear 8, gear 9, gear 10, disjunctor gear 13 and gear 17, and final power input shaft 15, the driving device running realizes several work.When shelves example, power is by axle 4 inputs, and through gear 5 and disjunctor gear 2, disjunctor gear 8 is again through gear 9, gear 10, disjunctor gear 13 and gear 17, final power input shaft 15, and the driving device counter-rotating realizes reverse gear and other operation.
