Abstract
The utility model discloses a belt drive wheel differential lock device of tractor, which comprises a differential head on the differential assembly, a half shaft bushing connected to the gearbox body; a half shaft in the half shaft bushing, a jointed set which is arranged on the half shaft bushing and can be combined with the end face of the differential head; the differential lock shell is arranged on the upper plane of half shaft bushing; the plectrum axis that can slide around is arranged in the differential lock shell; the plectrum axis is provided with a spring; the plectrum that can slide the jointed set on the plectrum axis; at the end of the differential lock shell, a rocker joystick that can slide the plectrum axis is arranged through the rocker block; a square-jaw is arranged on the end of the combining surface of jointed set and differential head correspondingly. Based on the present structure, the utility model adjusts and adds certain components, and then the problem of road sliding of the belt drive wheel tractor is solved. The utility model has advantages of simple structure, easy manipulation and low manufacturing costs.
Description
Technical field
The utility model relates to the wheeled tractor differential of a kind of belt transmission locking device.
Background technique
At present, the wheeled tractor overwhelming majority of belt transmission does not have the differential locking device, this tractor travels on the road surface of mire and road conditions inclement condition, when wherein a driving wheel skids, because the effect of differential mechanism, another driving wheel then stops operating, and tractor can not roll away from by self power and be detained the area, causes difficulty for tractor field work.
Summary of the invention
The technical problems to be solved in the utility model provides the wheeled tractor differential of a kind of belt transmission locking device, to overcome the problem that the wheeled tractor of belt transmission can not travel because of slipperiness on roads.
For solving the problems of the technologies described above, the utility model comprises the differential cover on the differential assembly, be connected to the axle tube on the gear box casing, place the semiaxis in the axle tube, its structural feature is to be set with the clutch collar that can combine with the differential cover end face on the described semiaxis; The differential lock housing is installed on plane on the axle tube, the declutch shift shaft that can horizontally slip is installed in the differential lock housing, declutch shift shaft is provided with spring, and declutch shift shaft is provided with the shift fork of stirring clutch collar; End at the differential lock housing is equipped with the rocking arm operating handle of stirring declutch shift shaft by rocker arm bracket.
Described clutch collar and differential cover be provided with the embedding of rectangle tooth in conjunction with corresponding on the end face.
After adopting said structure, only on the existing structure basis, adjust, increase the part parts, promptly solved the problem that the wheeled tractor of belt transmission can not travel because of slipperiness on roads, have simple in structure, handiness, the characteristics of low cost of manufacture, and improved working efficiency greatly, reduced labor intensity.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
With reference to accompanying drawing, the wheeled tractor differential of this belt transmission locking device, comprise the differential cover 1 on the differential assembly 25, be connected to the axle tube 7 on the gear box casing 24, place the semiaxis 4 in the axle tube 7, be set with the clutch collar 2 that can combine with differential cover 1 end face at semiaxis 4, clutch collar 2 is installed on the semiaxis 4 by spline, clutch collar 2 and differential cover 1 be provided with the embedding of rectangle tooth in conjunction with corresponding on the end face; Differential lock housing 19 is installed on plane on the axle tube 7, be lined with paper washer 6 between differential lock housing 19 and the axle tube 7, and be fixed on the axle tube 7 by bolt 8, spring washer 9, the declutch shift shaft 5 that can horizontally slip is installed in the differential lock housing 19, declutch shift shaft 5 is provided with spring 20, declutch shift shaft 5 is provided with the shift fork 3 of stirring clutch collar 2, and the socket of shift fork 3 inserts in the circular groove of clutch collar 2, and leans on spring 20 to give and tightly defeat tightly; The rocking arm operating handle 16 of stirring declutch shift shaft 5 is installed by rocker arm bracket 15 in differential lock housing 19 ends; rocker arm bracket 15 is fixed on the differential lock housing 19 by bolt 18, spring washer 17; rocking arm operating handle 16 is installed on the rocker arm brackets 15 by bearing pin 12, packing ring 13 and cotter pin 14; axle head at the declutch shift shaft 5 of rocking arm operating handle 16 ends is processed with screw; be equipped with on the screw and regulate bolt 10 and locking nut 11; on the end face of the differential lock housing 19 of the other end capping 21 is installed relatively, and is fastened on the differential lock housing 19 by bolt 22, spring washer 23.This device shows the situation that is installed on the right axle shaft.
Working principle of the present utility model is: when pulling the rocking arm operating handle to the right, the rocking arm that links together with operating handle will clockwise rotate, the adjusting bolt that its lower end promotes to be fixed on the declutch shift shaft moves to left, promote the shift fork in the housing, pressure spring moves to left simultaneously, under the shift fork effect, clutch collar moves to left and combines with tooth embedding on the differential cover, and right axle shaft and differential casing are fused.When unclamping the rocking arm operating handle, clutch collar moves to right under the effect of spring immediately, and separates with differential cover, removes the differential lock effect.Make when engaging differential lock, should at first separate tractor clutch, cut off driving force, the to be driven wheel rejoined when stopping operating.
