Abstract
The utility model relates to a new style boat tractor propelled by four wheels without guiding wheels, which is designed with inside and outside toothed steering clutches. The inside and outside teeth can respectively transfer the power to the front and back the driving wheels on one side, or respectively stop the dynamic force of the front and back driving wheels on one side. Consequently two turning methods of turning large curve and turning small curve are realized. The utility model has the advantages of soft turning, good straight line driving performance, labor saving, long service life, simple structure, low cost, and not easy slipping and sinking of boat tractor.
Description
The utility model is a kind ofly to be used to plough and the four wheel drive boat tractor of land transport.
The jaw clutch of existing four wheel drive boat tractor (Wan County-12 type four wheel drive boat tractor) is the two-way jaw clutch that adopts.Because the four wheel drive boat tractor is to utilize jaw clutch to turn to, so design has the four wheel drive boat tractor of two-way jaw clutch just to exist yaw serious, linear driving performance is poor; Handle effort; Turn to tooth embedding load big, the life-span is shorter; Easily cause the shortcomings such as falling into car of skidding.
The purpose of this utility model is a kind of novel no directive wheel four wheel drive boat tractor that designs in order to overcome above shortcoming.
As shown in drawings, this four wheel drive boat tractor is made up of rear drive case (1), transfer case (2), front wheel driving case (3), gearbox (4), inner teeth (6), outer tooth embedding (7) and return spring (5), inner teeth is connected on the driving shaft and can slides on driving shaft with spline, and transmits moment of torsion.Outer tooth embedding is connected on the inner teeth and can slides relatively with spline, and the tooth embedding can separate respectively, only separates an external tooth embedding or inner teeth is successively separated with its mutually meshing tooth embedding, can make the boat tractor large radius turn or change little curved.
The four wheel drive boat tractor of making by above-mentioned design has following advantage:
1. turn to softlyer, linear driving performance is better, turns to big bending formula, and radius of turn is big, the complete machine swing is also less, and farm implements are thereafter also swung less, and the complete machine linear driving performance is just improved by contrast.
2. handle laborsavingly, the field general large radius turn that only needs of when guiding only needs to handle the outer tooth embedding in the transfer case this moment, blocks the power of a side front-wheel, and the moment of torsion that general front-wheel rotates has only 1/2 of trailing wheel, so compared with prior art its steering force also reduces 1/2.
3. turn to that tooth embedding load reduces, the life-span is longer.Because transfer case dens in dente embedding quantity doubles, and what often need to separate is outer tooth embedding, and the moment of torsion that outer tooth embedding is transmitted is littler, and load also lacks, and the life-span prolongs naturally.
4. be difficult for the sunken car that skids, when leading in the field, general turns to the large radius turn form, three driving wheels is arranged in work this moment, and tractive force can increase by 1/2, and resistance also reduces 1/2, so boat tractor is difficult for sinking because of sliding.
5. be tangible in the superiority aspect simplified structure, the reduction accuracy of manufacture and the cost.
Accompanying drawing is the system schematic of four wheel drive boat tractor.
Below in conjunction with description of drawings embodiment of the present utility model and operation principle.
The utility model is made up of rear drive case, transfer case, front wheel driving case, inner teeth, outer tooth embedding and return spring, inner teeth is connected on the driving shaft with spline, can on driving shaft, move and transmit moment of torsion, outer tooth embedding is connected on the inner teeth with spline, inside and outside tooth embedding can be slided relatively, and make inside and outside tooth embedding self-return with return spring respectively, be in normal engagement.
Steering principle of the present utility model has dual mode, as turn left to: during large radius turn, the outer tooth embedding in the transfer case of the left side separates with the tooth embedding on the gear Z12, and the power of left side front-wheel is blocked, inner teeth still combines with tooth embedding on the gear Z14, and left rear wheel still works on.This moment, complete machine had three driving wheels in work, and the near front wheel stops operating, and the resistance of generation is less, and complete machine turns to bigger radius of turn.Change little when curved, the inside and outside tooth embedding in the transfer case of the left side all separates with tooth embedding on the Z14 with Z12.The power of driving wheel is blocked before and after the left side, and boat tractor is turned with small radii.
Claims (3)
1, a kind of four wheel drive boat tractor.Form by rear drive case (1), transfer case (2), front wheel driving case (3), gearbox (4) and tooth embedding.It is characterized in that said tooth is embedded with inner teeth (6) and outer tooth embedding (7) inner teeth is contained on the driving shaft.Outer tooth is inlaid on the inner teeth.Return spring (5) is housed in the inboard of inside and outside tooth embedding.
2,, it is characterized in that inner teeth is connected with spline with driving shaft according to the said four wheel drive boat tractor of claim 1.
