The natural conditions of China various places and cropping system have very big-difference, and Plain, mountain region, terraced fields are arranged, and nonirrigated farmland, paddy field are arranged, and have flat work, furrow to do, and in addition, also have results in rainy season etc.; Therefore, harvest machinery is that working part or running gear all will have bigger comformability.Existing wheel type harvester steeraxle is mainly by wheel hub, steering swivel and turn to crossbeam etc. to form.Because wheeled steeraxle uses the guiding tire, rolling resistance is big on mellow soil, and particularly paddy field and rainy season, rolling resistance is bigger, is difficult for harvest machinery and develops to large-scale direction.Simultaneously, existing wheel type harvester adds the part by weight number of harvest machinery itself because the weight of silo almost all drops on the steeraxle, and the load ratio that steeraxle bears is bigger; Also having restricted harvest machinery develops to large-scale direction.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of load-bearing big, turn to flexibly, the steering drive axle of wheel type harvester of wide accommodation.
For solving the problems of the technologies described above, the present invention includes the main speed reduction box housing and be installed in the right axle shaft sleeve pipe at main speed reduction box housing two ends and the steering drive axle housing that the left half axle sleeve pipe is formed, the top of main speed reduction box housing is provided with waves the axle mounting hole, its constructional feature is in the main speed reduction box housing diff to be installed, main speed reduction box housing front is equipped with and described diff power bonded assembly main gear assembly, be hinged with wheel reduction gear at steering drive axle housing two ends, the transmission shaft that connects diff and wheel reduction gear is housed in the steering drive axle housing; Be hinged with double acting between left half axle sleeve pipe and hinged thereon the wheel reduction gear and turn to oil cylinder, be hinged with steering track rod between two wheel reduction gears.
Described main gear assembly comprises and is installed in main speed reduction box housing fwd differential mounting, and gear wheel shaft is installed in the differential mounting, and gear wheel shaft the inner is equipped with the little spiral bevel gear of the big spiral bevel gear ingear of diff, outer end the input butt flange is installed.
Described main speed reduction box housing two ends are provided with inner stopper, and the inner relatively correspondence of described right axle shaft sleeve pipe and left half axle sleeve pipe is provided with outer stopper.
Described right axle shaft sleeve pipe and left half axle sleeve pipe are rectangular.
Described wheel reduction gear comprises the steering swivel housing, on the steering swivel housing wheel hub is installed, be connected sun wheel on the transmission shaft, be installed in pinion carrier on the wheel hub, be installed in the compensating-gear shaft on the pinion carrier, with the sun wheel engagement and be installed in compensating-gear shaft planetary wheel, with planetary wheel engagement and the internally toothed annulus of indirect securement on the steering swivel housing.
Described transmission shaft is two V shape universal joint shafts.
After adopting said structure, owing in the main speed reduction box housing, be equipped with and main gear assembly power bonded assembly diff, two ends are hinged with and diff power bonded assembly wheel reduction gear, make steeraxle become steering drive axle, the load-carrying properties and the tractive performance of steeraxle have been improved, and turn to flexibly, improved the adaptive capacity of wheel type harvester.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
