Abstract
The utility model discloses an inner-tooth type steering mechanism for a small hand tractor, which comprises steering shafts (7), a speed reduction shaft (11), a left and a right driving wheel shafts (16, 13), a central transmission gear (6), a left and a right reduction gears (14, 10) and a left and a right driving gears (15, 12), wherein the steering shafts (7) on both sides of the central transmission gear (6) are provided with steering gears (5, 9). The left and the right steering gears (5, 9) are respectively engaged with inner teeth on both sides of the central transmission gear (6); the steering shafts (7) on the outer sides of the left and the right steering gears (5, 9) are respectively provided with a steering spring (3) and a bearing (1); the left and the right steering gears (5, 9) are correspondingly provided with a left and a right steering shifting forks (4, 8), and are orderly engaged with the left and the right reduction gears (14, 10). After the structure is adopted, the engaging and disengaging of the left and the right steering gears (5, 9) with the central transmission gear (6) can be quickly realized to realize left and right steering just by overcoming the elastic force of the steering spring (3). The utility model has the advantages of simple and compact structure, convenient operation, flexible steering, etc.
Description
Technical field
The utility model relates to a kind of steering hardware, particularly a kind of steering hardware that is applicable to small hand tractor.
Background technology
At present, the steering hardware of the small hand tractor below 15 horsepowers all adopts castellated engaging and disengaging gear, and big, the feel of clutch action power was heavy when its weak point was to turn to clutch, turns to difficulty during the farm work when the mud pin is dark especially, and labour intensity is big.
Summary of the invention
In order to solve the above-mentioned disadvantage that the small hand tractor steering hardware exists, problem to be solved in the utility model provide a kind of simple and compact for structure, operation is light, turn to flexibly, small hand tractor internal-gear type steering hardware that result of use is good.The technical scheme that its technical matters that solves the utility model adopts, it comprises steering shaft, deboost axle, the left and right sidesing driving wheel axle, be arranged on the central driver gear on the steering shaft, be arranged on left and right sides reducing gear and the corresponding left and right sides driven wheel that is fixed on the left and right sidesing driving wheel axle on the deboost axle, left and right sides driven wheel meshes with left and right sides reducing gear successively, the steering shaft of described central driver gear both sides is provided with left and right sides steering gear, left and right sides steering gear respectively with the internal gearing of central driver gear both sides, on the steering shaft in the left and right sides steering gear outside, be respectively equipped with and turn to spring, turn to pad and bearing, about correspondence is provided with on the steering gear of the left and right sides, turn to shift fork; Left and right sides steering gear meshes with left and right sides reducing gear successively.
After adopting said structure, since left and right sides steering gear respectively with the internal gearing of central driver gear both sides, when about handling, turning to shift fork to turn to, only need overcome the internal tooth clutch that turns to spring force just can realize left and right sides steering gear and central driver gear fast, thereby turn to about realizing; Have advantages such as simple and compact for structure, that operation is light, turn to flexibly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, specific embodiments for a kind of small hand tractor internal-gear type of the utility model steering hardware, it comprises steering shaft 7, deboost axle 11, left and right sidesing driving wheel axle 16,13, be arranged on the central driver gear 6 on the steering shaft 7, be arranged on the left and right sides reducing gear 14 on the deboost axle 11,10 and correspondence be fixed on left and right sidesing driving wheel axle 16, left and right sides driven wheel 15 on 13,12, steering shaft 7, deboost axle 11, left and right sidesing driving wheel axle 16,13 are fixed on the casing by bearing 1 respectively, left and right sides driven wheel 15,12 successively with left and right sides reducing gear 14,10 engagements, the steering shaft 7 of described central driver gear 6 both sides is provided with left and right sides steering gear 5,9, left and right sides steering gear 5,9 respectively with the internal gearing of central driver gear 6 both sides, at left and right sides steering gear 5, be respectively equipped with on the steering shaft 7 in 9 outsides and turn to spring 3, turn to pad 2 and bearing 1, at left and right sides steering gear 5, turn to shift fork 4 about correspondence is provided with on 9,8; Left and right sides steering gear 5,9 meshes with left and right sides reducing gear 14,10 successively.
Principle of work of the present utility model is as follows: central driver gear 6 and 5,9 engagements of the left and right sides steering gear during normal rotation, left and right sides steering gear 5,9 meshes with left and right sides reducing gear 14,10 successively, left and right sides reducing gear 14,10 meshes with left and right sides driven wheel 15,12 successively, rotates thereby drive left and right sidesing driving wheel axle 16,13.When rotating right steering shift fork 8, right steering shift fork 8 overcomes and drives right steering gear 9 behind the elastic force that turns to spring 3 and break away from internal gearing with central driver gear 6, and right steering gear 9, right reducing gear 10, right driven wheel 12 and right live axle 13 stop operating; Drive bottom left steering gears 5 at central driver gear 6 and drive left reducing gear 14, left driven wheel 15 and left driving wheel axle 16 and rotate, thus realize the small hand tractor right-hand turning to; After unclamping right steering shift fork 8, under the elastic force effect of spring 3, right steering gear 9 internal gearing automatic again and central driver gear 6 resets.When rotating left steering shift fork 4, and rotate right steering shift fork 8 in like manner, small hand tractor then left-handed turning to.
