The effect of the convenient multifunctional horizontal discharger is beneficial in that, the utility model discloses a system pressure is establish in the damping hole, makes rear wheel motor production drive do all can, the work of drive vehicle, and it can't the normal condition of working to avoid the front wheel to skid the back system.
Description
Technical field
This utility model relates to self propelled harvester and drives field, especially a kind of self propelled harvester hydraulic pressure four-wheel drive shoe.
Background technology
At present; import and high-end self propelled harvester adopt hydraulic pressure four-wheel drive structure; hydraulic pressure four-wheel drive structure has the disadvantage that the phenomenon that some tyre slip car load cannot be walked often occurs in muddy ground condition in self propelled harvester, also there will be the problems referred to above from the self propelled harvester tool industry in external importer.
Owing to before and after 4 wheel driven, motor hydraulic circuit is shunt circuit, when front-wheel skids, hydraulic oil can flow to the front motor side that pressure is relatively low, now system can not build-up pressure, cause that rear motor is without driving force, four-wheel drive is ineffective.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of self propelled harvester hydraulic pressure four-wheel drive shoe.
For achieving the above object, this utility model adopts following technical proposals:
Self propelled harvester hydraulic pressure four-wheel drive shoe, including hydraulic manifold block, hydraulic flange, pipe joint, electromagnetic valve, pilot valve, controller, pump and speed probe, hydraulic flange and pipe joint are set outside hydraulic manifold block, the front wheels and rear wheels of self propelled harvester is respectively provided with speed probe, described pilot valve is arranged on hydraulic oil input channel, described pumping is arranged in parallel damping hole on hydraulic fluid port pipeline between pilot valve and motor, described electromagnetic valve, speed probe is all connected with controller, described controller realizes the commutation of pilot valve by the opening and closing of electromagnetic valve.
Preferably, described self propelled harvester hydraulic pressure four-wheel drive shoe also includes overflow valve, and described overflow valve is arranged on the pipeline between pilot valve and motor.
By arranging overflow valve, effectively prevent the pipeline pressure between pilot valve and motor too high, thus improve the safety that whole device uses.
Preferably, described self propelled harvester hydraulic pressure four-wheel drive shoe also includes repairing check valve, and described repairing check valve is in parallel with overflow valve.By arranging repairing check valve, effectively prevent motor from situation about being emptied occurring.
The beneficial effects of the utility model are, this utility model sets up system pressure by damping hole, make rear wheel motor produce driving force, drive vehicle operation, it is to avoid after front-wheel skids, system cannot the situation of normal operation.

Fig. 1 is the three-dimensional structure diagram of the self propelled harvester hydraulic pressure four-wheel drive shoe that this utility model provides；
Fig. 2 is the hydraulic schematic diagram of the self propelled harvester hydraulic pressure four-wheel drive antiskid valve that this utility model provides；
Wherein 1. hydraulic manifold block, 2. hydraulic flange, 3. pipe joint, 4. anti-slip valve, 5. electromagnetic valve, 6. repairing check valve, 7. overflow valve, 8. damping hole, 9. pilot valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As shown in Figure 1, self propelled harvester hydraulic pressure four-wheel drive shoe, including hydraulic manifold block 1, hydraulic flange 2, pipe joint 3, anti-slip valve 4, controller, pump and speed probe, hydraulic manifold block 1 is outside arranges hydraulic flange 2 and pipe joint 3, the front wheels and rear wheels of self propelled harvester is respectively provided with speed probe, described electromagnetic valve 4 is arranged on hydraulic oil input channel, described pumping is arranged in parallel damping hole 8 on hydraulic fluid port pipeline between pilot valve 9 and motor, described electromagnetic valve 5, speed probe is all connected with controller, described controller realizes the commutation of pilot valve 9 by the opening and closing of electromagnetic valve 5.
Preferably, described self propelled harvester hydraulic pressure four-wheel drive shoe also includes overflow valve 7, and described overflow valve 7 is arranged on the pipeline between pilot valve 9 and motor.
Preferably, described self propelled harvester hydraulic pressure four-wheel drive shoe also includes repairing check valve 6, and described repairing check valve 6 is in parallel with overflow valve 7, by arranging repairing check valve 6, effectively prevents motor from situation about being emptied occur.
This utility model self propelled harvester hydraulic pressure four-wheel drive shoe work process is as follows:
As it is shown in figure 1, the hydraulic oil of self propelled harvester is flowed out by pump, hydraulic oil enters front wheel motor by adpting flange 2, and electromagnetic valve oil return is flowed in fuel tank by pipe joint 3.
As in figure 2 it is shown, A represents pumps hydraulic fluid port, B represents motor input, and T represents fuel tank input, and Ps represents that electromagnetic valve controls oil input port.
When self propelled harvester front-wheel skids, speed probe detection front wheel rotation speed and rear wheel rotation speed, and front wheel rotation speed and rear wheel rotation speed are transmitted to controller, described controller storage front wheel rotation speed and rear wheel rotation speed, front wheel rotation speed and rear wheel rotation speed are compared, if the ratio of front wheel rotation speed and rear wheel rotation speed exceedes setting ratio, controller electric conduction magnet valve, electromagnetic valve obtains electric, pilot valve commutates, the closedown of pipeline at pilot valve place, hydraulic oil is reached B point by A point by damping hole 8, this utility model arranges damping hole 8 on the pipeline between pilot valve and motor input, the pressure of system is set up by damping hole 8, motor is made to produce driving force, and then drive self propelled harvester work by motor.
When self propelled harvester front-wheel is non-slip, speed probe detection front wheel rotation speed and rear wheel rotation speed, and front wheel rotation speed and rear wheel rotation speed are transmitted to controller, front wheel rotation speed is compared by described controller with front wheel rotation speed setting value, if front wheel rotation speed is less than front wheel rotation speed setting value, then controller controls electromagnetic valve cut-off, and hydraulic oil reaches B point by pilot valve 9, reduces Hydraulic System Fever.
Detailed description of the invention of the present utility model is described in conjunction with accompanying drawing although above-mentioned; but the not restriction to this utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art need not pay various amendments or deformation that creative work can make still within protection domain of the present utility model.
