Description
Technical field:
The utility model relates to a kind of hand tractor of four-wheel drive.
Background technique:
Hand tractor is one of main agricultural machinery and implement of modern peasant; but the hand tractor on the market all is simple front-wheel drive; hand tractor like this is all right in the field farming; aspect transportation because the particularity of hand tractor; mainly at the field road; travel in the road in the rural area village; these road conditions are generally all very poor; the hand tractor of simple front-wheel drive is all very limited in these road driving transport capacities; front-wheel usually can occur and skid and do not make effectively, transport capacity is descended greatly, particularly mountain area upper level area and rainy day situation more complicated; aspect transportation, the hand tractor of simple front-wheel drive is not as good as livestock.
The model utility content:
At above-mentioned deficiency, the utility model proposes a kind of hand tractor of four-wheel drive, make its four-wheel drive, better bring into play its transport capacity in the rural area.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hand tractor of four-wheel drive, comprise gearbox, transmission shaft and front and back wheel, advancing and the linkage structure relation of reverse gear in the gearbox, original front wheel driving structure of hand tractor and farm work function keep original structure, the power of motor output is delivered in the gearbox first left end through clutch, it is characterized in that: second right-hand member extends on one section axle of gear box casing and installs first planetary differential additional in gearbox, planetary pinion in first planetary differential with fixedly connected second internal helical gear and the outer oblique gear that is sleeved on second and mesh simultaneously, by internal helical gear power and speed are passed to front wheel driving by the original linkage structure in the gearbox; Outer oblique gear is the combined structure with a coaxial drive wheel, by this drive wheel power and speed are delivered to one and are fixed on the adding on the axle of gear-box case body, add central helical gear and a diclinic gear engagement on the axle, this diclinic gear and a helical gear engagement that is positioned at the transmission shaft front end, drive second planetary differential that is installed on the trailer chassis rear-wheel spindle by transmission shaft, second planetary differential is realized rear driving to the transmission of power from gearbox to rear-wheel spindle.
The coaxial drive wheel of described outer oblique gear is gear or sprocket wheel.
The hand tractor of the four-wheel drive that the utility model provides, keep existing hand tractor front driving device and farm work function constant in, increased rear drive equipment, hand tractor can use front wheel driving or rear driving separately, when carrying out short-distance transport in order to increase the adhesion of trailing wheel to ground, can use rear driving separately, the tractive force of tractor is strengthened, reduce fuel consumption, exercise safer.Under the steep slope and slippery path condition, can use front wheel driving and rear driving that four-wheel is driven simultaneously, improve passing ability.The utility model is particularly suitable for using under upper level area, mountain area and the complicated bad situation of road conditions on rainy day.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
The hand tractor of this four-wheel drive that the utility model proposes is made up of the trailer chassis of improved gearbox and matching used band rear driving.
As shown in Figure 1, the same routine techniques of the internal structure of gearbox, the power of motor output is delivered to the left end of first I in the gearbox through clutch, and the original front driving device of hand tractor is also constant.Extend at the right-hand member of second II on one section axle of gear box casing and install first planetary differential 2 additional, this is the improvement of the utility model to gearbox.
There are a pair of planetary pinion 3 and internal helical gear 8 and outer oblique gear 7 often to mesh in first planetary differential 2.Internal helical gear is connected on second, and when the gear transmission power to the second on first spool was gone up, second planet pin 4 that directly drives in first planetary differential was again by the inside and outside helical gear of planetary pinion 3 drives that is installed in the planet pin two ends.By the coaxial central gear of internal helical gear, by the transmission in the gearbox driving force and speed are delivered to and realize front wheel driving on the front wheel spindle, front wheel spindle is made up of two semiaxis, and the external part of each semiaxis is installed left and right front-wheel 1 respectively.
Outer oblique gear 7 and in-line gears or sprocket wheel 5 link, by these in-line gears or sprocket wheel power and speed are delivered to a corresponding gear or a sprocket wheel 9 on the axle 10 of adding that is fixed on the gearbox outer wall, Figure 2 shows that and add axle and be connected part on the axle, by coaxial mounted helical gear 11 power and speed are delivered to a diclinic gear 12, diclinic gear and helical gear 13 engagements that are positioned at tractating bar intermediate solid drive shaft 14 front ends, drive second planetary differential 16 that is installed on the trailer chassis rear-wheel spindle 17 by transmission shaft, the rear-wheel spindle 17 that driving force from gearbox is passed to trailer chassis is realized rear driving, rear-wheel spindle is made up of two semiaxis, and the external part of each semiaxis is installed a left side respectively, off hind wheel 15.
Fig. 3 is the trailer chassis connection diagram of band rear driving, and trailing wheel wheel rim and two trailing wheel semiaxis are fixedlys connected.On two rear-wheel spindles a bearing support is arranged respectively, bearing support is connected with the vibration damping leaf spring of trailer railway carriage, and one of bearing support roller circle is equipped with disk, and the brake drum that is equipped with on the disk on braking operator and brake shoe and two the trailing wheel wheel rims forms the trailing wheel braking.Tractating bar front end correct position has operating seat and trailing wheel braking control pedal, and the operating seat back is the tie point of trailer container and tractating bar.Container connects with adopting latch being connected of tractating bar.But plug just cruising of latch when putting into container.When needs were unloaded, pulling out latch, firmly to lift container front container just can be the low easier unloading in high back before the fulcrum rotation with two place's bearing supports on the trailing wheel semiaxis.
This tractor only needs the differential mechanism locking device 6 on the locking first planetary differential outer oblique gear when unloading trailer and need farming, disconnect the rear driving power that trailer chassis is given in shunting, just can use the front-wheel drive farming separately.But when loading onto the trailer operation, only need unclamp by needs the 6 just hauling operations of differential mechanism locking device.
Certainly, the improvement of this four-wheel drive hand tractor can be possible to the multiple hand tractor gearbox on the present market.Just at the improvement complexity difference of different speed changers, the utility model only is that the easiest improved a kind of gearbox is described.Other gearbox is delivered to the power of speed changer inside outside the gearbox by first planetary differential as long as use the technological scheme of putting down in writing as present patent application claims, carries out differential and branches to the front and back driving, just belongs to protection domain of the present utility model.First planetary differential can make integrated type or bulk-breaking assemblies; Differential spider pinion shaft and planetary pinion can be two, three or more.Differential mechanism locking device on the first planetary differential outer oblique gear also can be made various ways, can be bolt nut structure or latch structure etc., and the traction in the trailer drive system can be that integral body or number joint are formed.Differential spider pinion shaft and planetary pinion can be two or three or more a plurality of.The lubricating system of two planetary differentials can be to reserve oil hole filling lubricant oil or make filling lubricant oil in the casing, and these conversion all fall within the protection domain of the present utility model.
