Summary of the invention
At above-mentioned shortcoming, the purpose of this utility model be to provide a kind of can stepless 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 utility model is that a kind of maize harvesting machine hydraulic-driven running gear is characterized in that it comprises driving engine, belt pulley set, volume adjustable hydraulic pump, HM Hydraulic Motor, retarder, drg, propons and two wheels; The output shaft of driving engine and the input shaft of belt pulley set link together, and the output shaft of belt pulley set is connected to again on the input shaft of volume adjustable hydraulic pump, and volume adjustable hydraulic pump and HM Hydraulic Motor couple together with high pressure fuel pipe; Hydraulic motor output shaft is connected on the input shaft of speed reducer, the output of retarder be connected on the input shaft of propons behind the drg, the output of propons divides two-way, is connected respectively on two wheels; The oil outlet of volume adjustable hydraulic pump is connected to the oil inlet of HM Hydraulic Motor with high pressure fuel pipe, and the oil outlet of HM Hydraulic Motor also is connected to the oil inlet of volume adjustable hydraulic pump with high pressure fuel pipe, forms closed hydraulic loop.
The volume adjustable hydraulic pump that the utility model adopts is a kind of electric ratio discharge capacity control variable plunger pump that is specifically designed to closed hydraulic loop.Can control the hand of rotation of motor by the direction of control variable Hydraulic Pump output fluid, thereby realize advancing or moveing backward of vehicle.By control variable pump output fluid flow size, can control the output speed of motor, thus the control road speed.
The HM Hydraulic Motor that the utility model 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 utility model is compared with prior art had is: after the utility model used on the maize harvesting machine, speed of a motor vehicle adjustment did not have gear restriction, from low speed to high speed can stepless 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 utility model.
Specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of maize harvesting machine hydraulic-driven running gear is characterized in that it comprises driving engine 1, belt pulley set 2, volume adjustable hydraulic pump 3, HM Hydraulic Motor 4, retarder 5, drg 6, propons 7 and two wheels 8; The input shaft of the output shaft of driving engine 1 and belt pulley set 2 links together, and the output shaft of belt pulley set 2 is connected to again on the input shaft of volume adjustable hydraulic pump 3, and volume adjustable hydraulic pump 3 and HM Hydraulic Motor 4 usefulness high pressure fuel pipes 4.1 couple together; The output shaft of HM Hydraulic Motor 4 is connected on the input shaft of retarder 5, the output of retarder 5 be connected on the input shaft of propons 7 behind the drg 6, the output of propons 7 divides two-way, is connected respectively on two wheels 8; The oil outlet of volume adjustable hydraulic pump 3 is connected to the oil inlet of HM Hydraulic Motor 4 with high pressure fuel pipe 4.1, and the oil outlet of HM Hydraulic Motor 4 also is connected to the oil inlet of volume adjustable hydraulic pump 3 with high pressure fuel pipe 4.1, forms closed hydraulic loop.
Principle of work of the present utility model and working process are as follows:
Vehicle advances: driving engine 1 drives belt pulley set 2 rotations, and belt pulley set 2 drives the input shaft rotation of volume adjustable hydraulic pump 3; Chaufeur is placed on reversing handle when advancing gear, volume adjustable hydraulic pump 3 forwards output high pressure oil, and high pressure oil promotes HM Hydraulic Motor 4 and is rotated in the forward; HM Hydraulic Motor 4 is rotated in the forward, and after slowing down by retarder 5, drive drg 6, propons 7 and two wheels 8 and be rotated in the forward, thus the function that realization is advanced.
Vehicle backing: driving engine 1 drives belt pulley set 2 rotations, and belt pulley set 2 drives the input shaft rotation of volume adjustable hydraulic pump 3; When chaufeur was placed on backing car gear with reversing handle, volume adjustable hydraulic pump 3 is the output high pressure oil oppositely, and high pressure oil promotes HM Hydraulic Motor 4 contrarotations; HM Hydraulic Motor 4 contrarotations after retarder 5 decelerations, drive drg 6, propons 7 and 8 contrarotations of two wheels, thereby realize the function of reversing.
Car brakeing: driving engine 1 drives belt pulley set 2 rotations, and belt pulley set 2 drives the input shaft rotation of volume adjustable hydraulic pump 3; When chaufeur was placed on the braking gear with reversing handle, volume adjustable hydraulic pump 3 stopped to export high pressure oil, and HM Hydraulic Motor 4 stops operating; At this moment, the brake pedal of pilot control operator's compartment, 6 pairs of vehicles of drg are braked.
Vehicle speed variation: vehicle is when advancing or move backward, if change the angle of reversing handle, the flow of the output high pressure oil of volume adjustable hydraulic pump 3 can change, and the output speed of HM Hydraulic Motor 4 can and then change; Like this, the rotative 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.
