Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, the farm machinery that work efficiency is high
Crawler belt fluid pressure drive device.
For achieving the above object, the present invention uses following technical proposals: a kind of farm machinery crawler belt fluid pressure drive device, bag
Include hydraulic motor and the decelerator being connected with hydraulic motor；Described decelerator includes that one-level that the main shaft with hydraulic motor is connected is too
Sun wheel, secondary solar gear, the primary planet train engaged with one-level sun gear, secondary solar gear respectively, secondary planet train, with
The ring gear of secondary planet train engagement；Described hydraulic motor includes valve body and the cylinder component being connected with valve body, described valve body
Inside it is provided with a control cylinder component and becomes the change displacement valves open in usual of discharge capacity.
Described change displacement valves open in usual includes the valve pocket being located in valve body, the spool being located in valve pocket, and described valve pocket sets
Having the input hydraulic fluid port with the input and output oil communication in valve body and output oil port, described spool is provided with one can connect input
The variable section of hydraulic fluid port and output oil port, one end of described valve body inner spool be provided with spring that spool can be promoted to slide in valve pocket and
For fixing valve pocket the screw plug of bearing spring thrust, described screw plug is provided with drain tap, the valve at the other end of described spool
Body is provided with Variable Control hydraulic fluid port, and when Variable Control hydraulic fluid port does not has an oil pressure, spool is pressed to Variable Control hydraulic fluid port end limit position by spring
Put and make input hydraulic fluid port and output oil port be in maximum stream flow connected state.
The speed reducing ratio of described decelerator is 1,/23 1/17.
The speed reducing ratio of described decelerator is 1/20.8.
During work, the main shaft of hydraulic motor impart power to one-level sun gear, primary planet train, secondary solar gear,
Secondary planet train and ring gear, when the Variable Control hydraulic fluid port of change displacement valves open in usual does not has pressure, spring promotes spool to arrive
Extreme position, now spool is connected input hydraulic fluid port and output oil port and is in maximum pump discharge connected state, and now motor displacement subtracts
Little, rotating speed raises, and output moment of torsion reduces；When the Variable Control hydraulic fluid port pressure of change displacement valves open in usual raises, spool overcomes bullet
The elastic force of spring moves, and the communication gap becoming displacement valves input hydraulic fluid port and output oil port diminishes until closing, defeated with time-varying displacement valves
Oil-out gradually connects with the drain tap becoming displacement valves until maximum, so that motor displacement increases, rotating speed reduces, and exports moment of torsion
Increase.
The invention has the beneficial effects as follows: the present invention combines farm machinery operating feature, on the basis of original running gear,
Reduction box part redesigns, and adjusts speed reducing ratio, it is ensured that the speed of agricultural machinery 200m/min；Motor portion is become discharge capacity
Valve redesigns, and under normality, motor performs high rotating speed so that it is be applicable to farm machinery industry；The present invention can simplify tradition
Farm machinery crawler haulage system, improves working performance, is a kind of novel hydraulically powered structure innovation of farm machinery crawler belt
Product.
