Description
[technical field] the utility model is a kind of trac., is a kind of new-type four wheel drive frame-steered tractor specifically.
[background technology] is current, and the four wheel drive frame-steered tractor of China's production and selling, is divided into three types substantially: one is head and trailer is all adopt Mechanical Driven; One is that head adopts Mechanical Driven, and trailer adopts hydraulic-driven; Another kind is that head adopts hydraulic-driven, and trailer adopts Mechanical Driven., although all improve the carrying capacity of trac. at hillside fields and complicated ground, all there is some defect in these three kinds of transporting tractors.Mainly: head and trailer are all adopt mechanically operated trac., adopt auxiliary gear box and transmission shaft to carry out hard transmission because front and back drive, there is the synchronous difficulty of front and back wheel large, form internal motivation circulation, parts easily damage; Head adopts Mechanical Driven, trailer adopts hydraulically powered trac., there is propulsive effort deficiency, the drawback that driving efficiency is low; Head adopts hydraulic-driven, and trailer adopts mechanically operated trac., there is complex structure, and cost is higher, handles loaded down with trivial details, and user's difficulty gives acceptance.I am according to the experience being engaged in the research and extension of four wheel drive frame-steered tractor for many years, by repetition test with constantly bring forth new ideas, successfully have developed a kind of four wheel drive frame-steered tractor of entirely new kind.
[summary of the invention], in order to do improving and innovation of existing trac. well, the utility model provides a kind of new-type four wheel drive frame-steered tractor.
For solving its technical matters, the technical solution adopted in the utility model is: 1. this trac. is made up of driving engine, power-transfer clutch, change speed gear box, hydraulic traversing mechanism, universal-joint, cone belt, driving pulley, negative pulley wheel, forerunner's transmission shaft, propons, prop shaft, back axle, trailer, front and back wheel and relevant steering unit.2. on the power take-off shaft of change speed gear box, installed two cover power output systems: a set of is hard transmission, namely directly drive back axle and trailing wheel by universal-joint, prop shaft, owner wants drive system; Another set of is soft-sphere model, namely drives propons and front-wheel by driving pulley, cone belt, negative pulley wheel, forerunner's transmission shaft, belongs to assistant drive system.3. change speed gear box, propons and back axle all adopt automobile gearbox and the back axle of existing commercially widely used maturation.4. on two front-wheels of propons, be provided with brake equipment respectively, the braking of single front-wheel can be realized.5. driving pulley and change speed gear box output flange are processed into single piece, active and passive belt pulley adopts 3 groove Type B belt pulleys respectively; 6. drive pulley wheel diameter is fixed value, and negative pulley wheel diameter is unanimously determined according to the linear velocity of front and back wheel.
The beneficial effects of the utility model are: 1. because this tractor rear wheel drives based on transmission shaft driven and hard transmission, main bearing capacity, on trailing wheel, has given full play to the advantage that mechanical drive transmission efficiency is high; F-w-d adopts belt-driving and soft-sphere model; because pulley drive has the function of overload protection; in case of f-w-d and back-wheel drive have an out of step conditions time, belt-driving regulates voluntarily by skidding to be carried out synchronous, thus actv. is avoided internal motivation to circulate, decreased parts and damage.2. because this trac. is provided with two cover power output systems, both can use two cover power output systems simultaneously, carry out four wheel drive; Also can individually use f-w-d or back-wheel drive, the different demands of user can be met.3. because the two cover power output systems of this trac. export respectively by just carrying out after change speed gear box speed change, ensure that f-w-d and the back-wheel drive energy whole process when each gear is synchronous.4. due to two front-wheels of this farm tractor front axle being provided with brake equipment respectively, in case of single front-wheel skid time, the braking to this skidding front-wheel can be realized, thus substantially increase and pass through performance.5. because this trac. adopts automobile gearbox and the vehicle bridge of existing commercially widely used maturation, thus enable manufacturing enterprise purchase conveniently, produce easily, reliable product quality, cheap, easy and simple to handle, the relieved use of user.
[accompanying drawing explanation] the utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, Fig. 2 are structural representation of the present utility model.
In figure: 1 driving engine, 2 power-transfer clutchs, 3 front axle assys, 4 front-wheels, 5 transmission assemblies, 6 articulated mountings, 7 universal joint assemblies, 8 prop shaft, 9 back axle assemblys, 10 trailing wheels, 11 trailers, 12 front-wheel brakes, 13 hydraulic traversing mechanisms, 14 main shift levers, 15 bearing circle, 16 steering cylinders, 17 driving pulleys, 18 cone belt, 19 negative pulley wheels, 20 forerunner's transmission shafts, 21 forerunner's transmission shafts bearings, 22 forebaies.
[detailed description of the invention] is with reference to accompanying drawing: mmi machine frame (22) is provided with driving engine (1), transmission assembly (5), front axle assy (3), is provided with power-transfer clutch (2) between driving engine (1) and transmission assembly (5); Front axle assy (3) is provided with two front-wheels (4), every front-wheel (4) is provided with front-wheel brake (12); Front axle assy (3) is connected with transmission assembly (5) output shaft by forerunner's transmission shaft (20), forerunner's transmission shafts bearing (21), negative pulley wheel (19), cone belt (18), driving pulley (17); Trailer (11) is provided with back axle assembly (9), trailing wheel (10), is connected with driving pulley (17) by prop shaft (8), universal joint assembly (7) between back axle assembly (9) with transmission assembly (5) output shaft; Hydraulic traversing mechanism (13) is arranged on above the front end of transmission assembly (5), by steering cylinder (16) and articulated mounting (6), forebay (22) is connected with trailer (11).The working process of this trac. is: a. four wheel drive process.Start the engine (1), in conjunction with power-transfer clutch (5), driving engine (1) is made to drive transmission assembly (5) work, the power of transmission assembly (5) is exported by two cover power output systems: a set of is import back axle assembly (9) by driving pulley (17) and universal joint assembly (7) into prop shaft (8), thus drives trailing wheel (10) work; Another set of is import front axle assy (3) into by driving pulley (17), cone belt (18), negative pulley wheel (19), forerunner's transmission shaft (20), thus drives front-wheel (4) work to carry out four wheel drive.During skidding as single in front-wheel (4), then use front-wheel brake (12) to implement single braking, thus ensure that forerunner normally works.D, synchronizing process.One is the diameter by reasonable disposition driving pulley (17) and negative pulley wheel (19), thus ensures that front-wheel (4) is consistent with the linear velocity of trailing wheel (10); Two is in real work, in case of front-wheel (4) and trailing wheel (10) have an out of step conditions time, because belt-driving has overload protection function, cone belt (18) regulate voluntarily by skidding carry out synchronous.C. steering operation process.Steering dish (15), promotes forebay (22) by steering cylinder (16), makes it to produce between articulated mounting (6) to rotate, thus realizes articulated steering.
