Abstract
The utility model relates to a turning mechanism of a mini-size tractor, which is composed of ratchet wheels (16) and ratchet pawls (15). The ratchet wheels (16) are fixed onto a drive shaft (10), wherein, the ratchet pawls (15) are connected to a drive wheel (7). When the utility model needs to turn right, a left handle can be slightly stressed, the left driving rotary speed is caused to increase, and the turning mechanism of a mini-size tractor can turn right. When the utility model turns left, the operation is reverse.
Description
The utility model relates to a kind of turning mechanism of mini tractor.
Domestic existing compact tractor turning mechanism adopts diff and dental clutch respectively at present, and diff one side wheel can occur and not rotate under the state of drive wheel friction unbalance stress, influence mechanical efficiency.Dental clutch owing to be subjected to the influence of between cog calibration, at steering angle hour, operate not steady, and steering unit complexity.
Task of the present utility model is: provide a kind of turning mechanism its make simple, installation volume is little, easy and simple to handle, the mini tractor of suitable especially little type.
Its solution is: at the axle drive shaft of trac. and the point of attachment of drive wheel, respectively design and installation click, when driving engine drove drive shaft turns, power drove drive wheel walking operation by ratchet, ratchet.But because the ratchet device mono-directional overrun, trac. only needs the swinging operation handgrip when turning, and can realize the differential turning.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model flow diagram that plows
Fig. 2 is Figure 1A-A cutaway view
Fig. 3 is that Fig. 2 B is to view
Among the figure: 1. driving engine; 2. frame; 3. bottom plate; 4. upper mounted plate; 5. front fork; 6. operator handle; 7. drive wheel; 8. sprocket wheel; 9. drive axle bed down; 10. axle drive shaft; 11. last driving axle bed; 12. traction frame; 13. Xiao's axle; 14. plough; 15. ratchet; 16. ratchet.
Driving engine in Fig. 1 (1) is fixed on the frame (2), be equipped with on last bottom plate (3) (4), the front fork (5) operator (6), traction frame (12), on drive axle bed (11) and frame (2) and be tightened to one, plough bearing pin (13) connects with traction frame (12), and upper and lower driving axle bed (11,9) is used for fixing axle drive shaft (10).
Ratchet among Fig. 2 (16) is fixed on the axle drive shaft (10), and ratchet (15) is installed on the drive wheel (7).
When power when speed-changing mechanism passes on the axle drive shaft, can combine it is together rotated with being connected in ratchet on the drive wheel (7) by the ratchet (16) that is fixed on the axle drive shaft (10), mini tractor just moves ahead and plows.When wanting right-hand corner, left hand makes left driving wheel can realize differential with the ratchet mono-directional overrun afterburning slightly, just can right-hand corner.Otherwise turnon left then.Operation is simple and reliable, and it is dexterous convenient to turn, particularly can the original place three-sixth turn.(so that wherein one to take turns be the center of circle).
The utility model is compared with prior art, and its prominent features is: solved public affairs Know the differential mechanism that the tractor turning mechanism adopts, driving wheel is easy on one side when farm work Skid, jaw clutch operating structure complicated difficult is with frauds such as separation, manufacturing cost height End can make mini tractor when neutral gear, arbitrarily turns.
Claims (1)
- A kind of turning mechanism of mini tractor, form by axle drive shaft, drive wheel, ratchet, ratchet, operator handle, but ratchet, ratchet mono-directional overrun, it is characterized in that: ratchet (16) is equipped with at axle drive shaft (10) two ends, ratchet (15) has been installed respectively on the drive wheel (7), operator has been installed on the front fork (5) (6).
