Description
Affiliated field
The utility model relates to a kind of four wheel drive walker tractor, the walker tractor of fluid motor-driven of a kind of trailer especially.
Background technology
At present, the widely used walker tractor in rural area mostly is a f-w-d, and the power of driving engine drives two front-wheels through power-transfer clutch, change speed gear box and steering clutch and rotates, and the drive car load advances or retreats.Walker tractor trailer wheel (hereinafter to be referred as trailing wheel) is a flower wheel, is not connected with actuating device.When transportation, the weight of goods is mainly by the trailing wheel load-bearing.Because the anterior deadweight of walker tractor is little, to ground-surface adhesive ability relative deficiency, can not produce enough tractive forces.Especially when the travels down of upward slope or mire, front-wheel skids and causes vehicle not walk.And, making wear on tyres serious because of front-wheel skids, consumption of fuel increases, and has influenced user's economic benefit, does not satisfy the needs of rural economic development.Learn that by retrieval the now existing many people of four wheel drive walker tractor have declared patent, and have formed certain productive capacity.But because mostly these four wheel drives are to provide power by the walker tractor change speed gear box, drive the rotation of trailer trailing wheel, form four wheel drive through mechanically operated mode.Though this structure solves above-mentioned existing problems, complex structure, fault is many, has influenced to popularize and promote.
Summary of the invention
In order to overcome the complex structure of existing walker tractor mechanical type four wheel drive, transmitted power is low, the deficiency that fault rate is high, the utility model provides the walker tractor of a kind of trailer with fluid motor-driven, it is not only simple in structure, tractive force is big, and stable performance, fault are few, flexible operation, consumption of fuel are little, and operating cost is low.
The technical scheme that its technical matters that solves the utility model adopts is: the trailer of being made up of gear type pump, distributing box, HM Hydraulic Motor, speed governing transmission gearbox, diff is with the walker tractor of fluid motor-driven, gear type pump is located at a side of walker tractor change speed gear box, also can be placed on the top or the bottom of change speed gear box, distributing box is located on the walker tractor control frame, be provided with diff on trailer axle, the vehicle frame of diff front portion is provided with speed governing transmission gearbox and HM Hydraulic Motor.
Described gear type pump is connected with sprocket wheel on the walker tractor change speed gear box power take-off shaft by axle head sprocket wheel, chain.
Described HM Hydraulic Motor is the rotating structure, and hydraulic motor output shaft is provided with sprocket wheel, and is connected with sprocket wheel on the speed governing transmission gearbox input shaft by chain.
The described diff that is located on the trailer axle, its input shaft is connected by the output shaft of universal-joint with the speed governing transmission gearbox.
The beneficial effects of the utility model are to draw power from change speed gear box, pass to trailer wheel by gear type pump, distributing box, HM Hydraulic Motor, speed governing transmission gearbox, diff, the change two-wheel drive is four wheel drive, increased the adhesive ability of car load, improved towability, solved walker tractor and skidded and the problem of consumption of fuel increase in the field or when going up a slope.Hydrostatic drive simultaneously is greatly improved operator's labor condition, and mechanism greatly simplifies, and efficient greatly improves.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, change speed gear box; 2, gear type pump; 3, oil pipe; 4, distributing box; 5, distributing box handle; 6, HM Hydraulic Motor oil pipe; 7, HM Hydraulic Motor; 8, speed governing transmission gearbox; 9, diff.
The specific embodiment
In Fig. 1, the trailer of being made up of gear type pump, distributing box, HM Hydraulic Motor, speed governing transmission gearbox, diff is with the walker tractor of fluid motor-driven, gear type pump (2) is located at a side of walker tractor change speed gear box (1), also can be placed on the top or the bottom of change speed gear box (1), distributing box (4) is located on the walker tractor control frame; Be provided with diff (9) on the trailer axle of trailer truck board bottom, the vehicle frame of diff front portion is provided with speed governing transmission gearbox (8) and HM Hydraulic Motor (7).Diff (9) can adopt the diff of miniature car or trac., and the output shaft of speed governing transmission gearbox (8) is connected by universal-joint with the diff input shaft.HM Hydraulic Motor (7) is the rotating structure, is connected with the input end of speed governing transmission gearbox (8) by sprocket wheel, chain.
During operation, gear type pump (2) is obtained power from walker tractor change speed gear box power take-off shaft, sprocket wheel, chain, make the fluid in the hydraulic reservoir arrive distributing box, with its process HM Hydraulic Motor oil pipe (6) liquid in-out pressure motor, make HM Hydraulic Motor (7) rotation through distributing box handle (5) by oil pipe (3).HM Hydraulic Motor (7) is passed to power speed governing transmission gearbox (8) again, and power is through the speed governing of speed governing transmission gearbox, and revolution is given diff with power through output shaft after reaching the design revolution, and the driving-trailer wheel rotates.The all dynamic input of the front and rear wheel of walker tractor like this, the structural shape of formation four wheel drive.
Claims (5)
1. a trailer is with the walker tractor of fluid motor-driven, form by gear type pump, distributing box, HM Hydraulic Motor, speed governing transmission gearbox, diff, it is characterized in that: gear type pump is located at a side of walker tractor change speed gear box, distributing box is located on the control frame of walker tractor, diff is located on the trailer axle, and the vehicle frame of diff front portion is provided with speed governing transmission gearbox and HM Hydraulic Motor.
