Description
Technical field
The present invention relates to a kind of running gear of maize harvesting machine, it adopts two front-wheels of a fluid motor-driven maize harvesting machine, realizes the car load walking.
Background technology
In order to realize the walking of maize harvesting machine, domestic existing self-propelled corn harvester adopts the mechanical type transmission usually.The power of engine output relies on the transmission of belt pulley, gearbox, brake and propons, finally drives the front-wheel rotation, realizes the function of car load walking.By switching four gears on the gearbox, realize the conversion of the speed of travel.Machine during operation, requires the speed of a motor vehicle slower between ground, uses the low-grade location on the gearbox this moment; During the machine transition, need the higher speed of a motor vehicle, use the high tap position on the gearbox this moment.Use the backing car gear on the gearbox during reversing, this moment, the front-wheel counter-rotating realized reversing.This mechanical type running gear has only fourth speed usually, can not realize stepless speed regulation.So between ground during operation, when running into the crop spacing and changing, be difficult in time adjust the suitable speed of a motor vehicle.And it is huge that the mechanical type running gear also has structure, from great shortcoming.
Summary of the invention
At above-mentioned shortcoming, the object of the present invention is to provide a kind of can continuous change, speed-change process steadily, no impact, compact conformation and the light maize harvesting machine hydraulic-driven running gear of own wt.
Technology contents of the present invention is that a kind of maize harvesting machine hydraulic-driven running gear is characterized in that it comprises engine, belt pulley set, volume adjustable hydraulic pump, hydraulic motor, decelerator, brake, propons and two wheels; The output shaft of engine and the power shaft of belt pulley set link together, and the output shaft of belt pulley set is connected to again on the power shaft of volume adjustable hydraulic pump, and volume adjustable hydraulic pump and hydraulic motor couple together with high-pressure oil pipe; Hydraulic motor output shaft is connected on the input shaft of speed reducer, the output of decelerator be connected on the power shaft of propons behind the brake, the output of propons divides two-way, is connected respectively on two wheels; The oil-out of volume adjustable hydraulic pump is connected to the oil-in of hydraulic motor with high-pressure oil pipe, and the oil-out of hydraulic motor also is connected to the oil-in of volume adjustable hydraulic pump with high-pressure oil pipe, forms closed hydraulic loop.
The volume adjustable hydraulic pump that the present invention adopts is a kind of electric ratio discharge capacity control variables plunger pump that is specifically designed to closed hydraulic loop.Can control the direction of rotation of motor by the direction of control variables hydraulic pump output fluid, thereby realize advancing or moveing backward of vehicle.By control variables pump output fluid flow size, can control the output speed of motor, thus the control road speed.
The hydraulic motor that the present invention adopts is a kind of quantitative piston motor that is specifically designed to closed hydraulic loop.It is a kind of two-way hydraulic motor, changes the direction that enters motor fluid and can change turning to of motor, changes the flow size that enters motor fluid, can change the rotating speed of motor.
The advantage that the present invention is compared with prior art had is: after the present invention used on the maize harvesting machine, speed of a motor vehicle adjustment did not have gear restriction, from low speed to high speed can continuous change; Speed-change process is steady, nothing is impacted; Machine when running into the crop spacing and changing, can in time be adjusted road speed when farm work.Hydraulic-drive running system compact conformation, own wt are light.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Specific embodiment
The present invention will be further described below in conjunction with concrete accompanying drawing.
As shown in Figure 1, a kind of maize harvesting machine hydraulic-driven running gear is characterized in that it comprises engine 1, belt pulley set 2, volume adjustable hydraulic pump 3, hydraulic motor 4, decelerator 5, brake 6, propons 7 and two wheels 8; The power shaft of the output shaft of engine 1 and belt pulley set 2 links together, and the output shaft of belt pulley set 2 is connected to again on the power shaft of volume adjustable hydraulic pump 3, and volume adjustable hydraulic pump 3 and hydraulic motor 4 usefulness high-pressure oil pipes 4.1 couple together; The output shaft of hydraulic motor 4 is connected on the power shaft of decelerator 5, the output of decelerator 5 be connected on the power shaft of propons 7 behind the brake 6, the output of propons 7 divides two-way, is connected respectively on two wheels 8; The oil-out of volume adjustable hydraulic pump 3 is connected to the oil-in of hydraulic motor 4 with high-pressure oil pipe 4.1, and the oil-out of hydraulic motor 4 also is connected to the oil-in of volume adjustable hydraulic pump 3 with high-pressure oil pipe 4.1, forms closed hydraulic loop.
The operation principle of the present invention and the course of work are as follows:
Vehicle advances: engine 1 drives belt pulley set 2 rotations, and belt pulley set 2 drives the power shaft rotation of volume adjustable hydraulic pump 3; The driver is placed on reversing handle when advancing gear, volume adjustable hydraulic pump 3 forwards output hydraulic oil, and hydraulic oil promotes hydraulic motor 4 and is rotated in the forward; Hydraulic motor 4 is rotated in the forward, and after slowing down by decelerator 5, drive brake 6, propons 7 and two wheels 8 and be rotated in the forward, thus the function that realization is advanced.
Vehicle backing: engine 1 drives belt pulley set 2 rotations, and belt pulley set 2 drives the power shaft rotation of volume adjustable hydraulic pump 3; When the driver was placed on backing car gear with reversing handle, volume adjustable hydraulic pump 3 is the output hydraulic oil oppositely, and hydraulic oil promotes hydraulic motor 4 reverse rotations; Hydraulic motor 4 reverse rotations after decelerator 5 decelerations, drive brake 6, propons 7 and 8 reverse rotations of two wheels, thereby realize the function of reversing.
Car brakeing: engine 1 drives belt pulley set 2 rotations, and belt pulley set 2 drives the power shaft rotation of volume adjustable hydraulic pump 3; When the driver was placed on the braking gear with reversing handle, volume adjustable hydraulic pump 3 stopped to export hydraulic oil, and hydraulic motor 4 stops operating; At this moment, the brake pedal of pilot control driver's cabin, 6 pairs of vehicles of brake are braked.
Vehicle speed variation: vehicle is when advancing or move backward, if change the angle of reversing handle, the flow of the output hydraulic oil of volume adjustable hydraulic pump 3 can change, and the output speed of hydraulic motor 4 can and then change; Like this, the rotary speed of two front-wheels also can change, thereby realizes the function of vehicle speed variation.The speed of vehicle can be from the zero-speed smooth change to maximum speed.
