Description
Technical field
The utility model belongs to mini-tiller technical field, and in particular to a kind of mini-tiller differential walking wheel assembly.
Background technique
Mini-tiller has light-weight, small in size, the features such as structure is simple using small diesel engine or gasoline engine as power.It is micro-
Cultivated machine is widely used in Plain, mountain area, the nonirrigated farmland on hills, paddy field, orchard etc..Mixing corresponding equipment can be drawn water, generated electricity, be sprayed
The operations such as medicine, spray can also draw towed vehicle and carry out short-distance transport, and mini-tiller can freely exercise in field, make convenient for user
With and storage, eliminating large-scale farm machinery cannot be introduced into the worry of mountain area field, be vast farmers consumer substitute ox plough
Optimal selection.
Miniaturization, the lightweight of mini-tiller are one of its developing direction, thus if using conventional agricultural machinery and implement on mini-tiller
Or the steering system on vehicle, then it will increase the volume, weight and complex degree of structure of mini-tiller, while cost also can be corresponding
It improves, therefore, is unfavorable for the popularization and use of mini-tiller.Therefore, it is directed to mini-tiller Steering at present, many producers all use
Differential mechanism solves, and makes the traveling wheel of mini-tiller fuselage two sides generate speed difference using differential mechanism, to realize mini-tiller
Steering or u-turn.
Open differential is made of parts such as planetary gear, planetary wheel carrier (differential carrier), axle shaft gears.Engine moves
Power enters differential mechanism through transmission shaft, directly drives planetary wheel carrier, then drive left and right two semiaxis by planetary gear, respectively drive it is left,
Right wheel.When cornering, since outboard wheel has the phenomenon that sliding drag, the phenomenon that nearside wheel trackslips, two driving wheels at this time will
The opposite additional force of both direction is generated, due to " minimum stream power ", necessarily causes the revolving speed of two sidecar wheels different, thus broken
It is broken the equilibrium relation of three, and by forcing planetary gear to generate rotation in semiaxis reflection to axle shaft gear, makes inside semiaxis
Spin down, outside semiaxis faster rotational speed, to realize the difference of both sides vehicle wheel rotational speed.
It can be seen that structure is complicated for differential mechanism, certain installation space is needed, for higher micro- cultivated to space requirement
For machine, the complete machine structure for the mini-tiller to be influenced that is bound to is laid out.
Do not depend on differential mechanism and can play the mechanism of differential steering it is, therefore, desirable to provide a kind of, and it is compact-sized, convenient for tearing open
Dress and maintenance.
Utility model content
It is fast using being mounted on traveling wheel the purpose of the utility model is to provide a kind of mini-tiller differential walking wheel assembly
Differential assembly to be changed, realizes that mini-tiller turns to, the quick change differential assembly structure is simple, compact, it is not take up mini-tiller fuselage space, and
It is convenient for disassembly and assembly, it is easy to later maintenance.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of mini-tiller differential walking wheel assembly, including traveling wheel, wheel shaft and quick change differential assembly, quick change differential assembly
Including bearing block and unilateral bearing, the bearing block is mounted on the inside of the wheel hub of traveling wheel, and the unilateral bearing is mounted on bearing
It is key connection between the outer ring and bearing block of unilateral bearing in seat, is key connection, wheel shaft between the inner ring and wheel shaft of unilateral bearing
Shaft end connected with the bolt being set on the outside of wheel hub mini-tiller host by wheel shaft drive traveling wheel march forward direction rotation,
The outside of the unilateral bearing is equipped with retaining ring, inside is equipped with circlip for hole and sealing ring.
The wheel shaft and six square shaft casings are fixedly connected, six square shaft casings be equipped with pin shaft and split pin, to it is micro-
Six sides for ploughing machine host export axis connection.
Flange on the bearing block is fixedly connected by bolt with the wheel hub.
Compared with prior art, the utility model has the beneficial effects that
In the utility model quick change differential assembly compared to differential mechanism for, it is simple and compact for structure, assembly when, it is only necessary to
With wheel hub and wheel shaft installation connection, either installation is still dismantled, convenient and efficient；Quick change differential assembly is integrally tied simultaneously
Structure after mounting, on the inside of the wheel hub of traveling wheel, will not occupy the space of mini-tiller fuselage, nor affect on other mechanisms in machine
Arrangement with it, therefore meet mini-tiller miniaturization, light-weighted trend；Quick change differential assembly utilizes set one-way shaft
It holds, since unilateral bearing only allows to rotate to a direction, the traveling wheel when mini-tiller needs to turn to, positioned inside
It is locked, the rotation of outside traveling wheel, and then realizes the purpose for turning to or reversing end for end.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Marked in the figure: 1, bearing block, 2, key I, 3, unilateral bearing, 4, key II, 5, pin shaft, 6, split pin, 7, six square shaft sets
Pipe, 8, six side's output shafts, 9, wheel shaft, 10, circlip for hole, 11, traveling wheel, 12, sealing ring, 13, wheel hub, 14, retaining ring,
15, hex bolts, 16, fixing bolt.
Specific embodiment
With reference to the accompanying drawing, the technical solution of the utility model is further described by specific embodiment.
As shown, a kind of mini-tiller differential walking wheel assembly, including traveling wheel 11, wheel shaft 9 and quick change differential assembly,
Traveling wheel 11 uses rubber wheel, and the convenient dismounting with 11 wheel hub 13 of traveling wheel, quick change differential group may be implemented in quick change differential assembly
Part includes the unilateral bearing 3 for being fixed on the bearing block 1 of 13 inside of wheel hub and being mounted in bearing block 1, both here and below, micro-
Ploughing the opposite one side of two traveling wheels 11 of machine is "inner", otherwise is "outside", and the flange of bearing block 1 and the wheel hub 13 pass through solid
To determine bolt 16 to be fixedly connected, the outside of unilateral bearing 3 is equipped with retaining ring 14, inside is equipped with circlip for hole 10 and sealing ring 12,
It realizes the axially position to unilateral bearing 3, is connected between the outer ring and bearing block 1 of unilateral bearing 3 by key 2 I, unilateral bearing 3
Inner ring and the wheel shaft 9 between connected by key II 4, transmitting of the power from wheel shaft 9 to wheel hub 13 is realized, in the outer of wheel hub 13
Side is equipped with hex bolts 15, and hex bolts 15 connects with 9 end of wheel shaft in bearing block 1, and 9 other end of wheel shaft is from bearing block 1
It is welded after middle stretching with six square shaft casings 7, six side's output shafts 8 of mini-tiller host are inserted into six square shaft casings 7, and pass through pin shaft
5 realize being fixedly connected for six side's output shafts 8 and six square shaft casings 7 with split pin 6.
After the utility model is mounted on mini-tiller, due to the effect of unilateral bearing, mini-tiller can be easily realized
It turns to and reverses end for end, without other labyrinths and control mechanism, therefore, easy to use, failure rate of machinery is low, dismounting convenience；
Further, since no matter mini-tiller host-initiated whether, mini-tiller can only all advance, and cannot fall back, therefore do not start when mini-tiller
When, the movement of mini-tiller position can also be easily realized, moreover, because in any case, mini-tiller cannot all be fallen back, therefore just
The anticollision device, collision-prevention device on mini-tiller can be saved, thus simplify mini-tiller mechanical mechanism and improve mini-tiller operation convenience and
Safety.
