Abstract
The invention discloses a four-wheel drive wheeled tractor with a hydraulically driven front axle. The tractor mainly comprises a front drive axle (1), an oil motor (2), an oil motor clutch (3), a change valve (4), a flow valve (5), a gear pump (6), a hydraulic oil tank (7), an oil inlet pipe (8), an oil return pipe (9), an oil discharging pipe (10), a high-pressure oil pipe (11) and a gear pump clutch (14) and is characterized in that: the oil motor (2) is arranged on the front drive axle (1); and the change valve (4) and the flow valve (5) are arranged on a front drive oil way. When the tractor works in a farmland, if rear driving wheels slip, the oil motor is started to drive front wheels to form four-wheel drive, so traction and adhesion performance of the tractor is greatly improved; the front and rear drive synchronous effect of the tractor is better by effectively controlling the speed of the front wheels through the flow valve (5); and the tractor has a simple structure, can be widely applied to all the wheeled tractors, new tractors and improvement of an old tractor, and is convenient to popularize and apply.
Description
[technical field] the present invention is a kind of trac., is that a kind of propons uses hydraulically powered four-wheel drive wheeled tractor specifically.
[background technology] in May, 2005, I have invented a kind of radial type four-wheel drive tractor of hydraulic driven trailer trailing wheel.In recent years, the user of many Northeasts called one after another, and can inquiry also load onto fluid pressure drive device on farm tractor front axle.It is reported, in the wheel-tire tractor that China peasant of the Northeast is had considerable part being arranged is two-wheel drive, in order to improve the traction carrying capacity of this part trac. when being engaged in farmland operation, many customer requirementies repack original two-wheel drive trac. into four-wheel drive wheeled tractor.And two-wheel drive to be repacked into four wheel drive, and maximum difficulty has two: one, and do not drive the power take-off implement of propons on the former chassis, and will on original chassis, install the before driving output unit additional, cost height not only, and also difficulty is big.The 2nd, synchronous effect is poor before and after the four-wheel drive wheeled tractor after the repacking.
[summary of the invention] repacks original two-wheel drive trac. into four-wheel drive wheeled tractor in order to adapt to user's request, the invention provides a kind of propons and uses hydraulically powered four-wheel drive wheeled tractor.
For solving its technical matters, the technical solution used in the present invention is: 1. install oil motor additional on the before driving vehicle bridge; 2. between oil motor and before driving vehicle bridge, install power-transfer clutch additional, in the time of need driving propons with oil motor power-transfer clutch is closed, when not needing power-transfer clutch is not separated with oil motor driving propons; 3. on the basis of former tractor hydraulic system, the gear type pump of the big discharge capacity that changes the outfit, and on the before driving oil circuit, install change-over valve and flow valve additional, with the driving direction of change-over valve control front driving wheel, with the speed of flow valve control front driving wheel.
The invention has the beneficial effects as follows: 1. owing on the before driving vehicle bridge, installed oil motor additional, trac. skids as rear drive sprocket when being engaged in farmland operation, then starts oil motor and drives the front-wheel rotation, form four wheel drive, strengthened the traction adhesion value and the work efficiency of trac. greatly; 2. owing between oil motor and before driving vehicle bridge, power-transfer clutch is housed, when not using oil motor to drive propons power-transfer clutch is not separated, do not increase the load that travels of trac.; 3. because change-over valve and flow valve have been installed on the before driving oil circuit, the travel direction and the speed of energy actv. control front driving axle make the front and back driving synchronous effect of trac. better; 4. because the present invention is simple in structure, installation and maintenance are convenient, can be widely applied to all wheel-tire tractors, both can be used for new machine, may be used on again in the old machine repacking, and are easy to utilize.
[description of drawings] the invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1 front driving axle, 2 oil motors, 3 oil motor power-transfer clutchs, 4 change-over valves, 5 flow valves, 6 gear type pumps, 7 hydraulic reservoirs, 8 oil inlets, 9 oil return pipes, 10 overflow oil tubes, 11 high pressure fuel pipes, 12 oil motor clutch control handles, 13 gear box of tractor bodies, 14 gear type pump power-transfer clutchs, 15 gear type pump clutch control handles.
[specific implementation method] is with reference to accompanying drawing: oil motor power-transfer clutch (3) is installed on front driving axle (1), oil motor (2) is installed on the oil motor power-transfer clutch (3), and being provided with oil motor clutch control handle (12), oil motor (2) links by two high pressure fuel pipes (11) and change-over valve (4); The return opening of change-over valve (4) communicates with hydraulic reservoir (7) by oil return pipe (9), between change-over valve (4) and the gear type pump (6) flow valve (5) is installed; One end of flow valve (5) directly links with change-over valve (4), and an end links by high pressure fuel pipe (11) and gear type pump (6), and the other end communicates with hydraulic reservoir (7) by overflow oil tube (10); Gear type pump (6) is installed on the gear box of tractor body (13) by gear type pump power-transfer clutch (14), and its oil suction links by oil inlet (8) and hydraulic reservoir (7), and oil outlet links by high pressure fuel pipe (11) and flow valve (5); Steerage gear pump clutch bar handle (15) can make gear type pump (7) be in work or off position.Specific operation process is: a, oil motor drive propons work.Steerage gear pump clutch bar handle (15) makes gear type pump (7) work; Pilot oil motor clutch bar handle (12) makes oil motor (2) and front driving axle (1) be in binding site; Handle change-over valve (4), make high pressure oil pass through high pressure fuel pipe (11) and drive oil motor (2) rotation and drive front driving axle (1) and advance or fall back.B, oil motor do not drive propons work.Steerage gear pump clutch bar handle (15) makes gear type pump (7) be in off position; Pilot oil motor clutch bar handle (12) makes oil motor (2) and front driving axle (1) be in disengaged position; Handle change-over valve (4), the return opening of change-over valve (4) is communicated with hydraulic reservoir (7) by oil return pipe (9).The actuating speed of C, adjustment propons.By adjusting flow valve (5), make part fluid flow into hydraulic reservoir (7) by overflow oil tube (10), by change flowing into the flow of change-over valve (4) mesohigh oil, changing the rotating speed of oil motor (2) and change the speed of front driving axle (1), driven in synchronism before and after realizing.
