Abstract
A vehicle backing device with small volume and simple structure which is suitable for miniature four wheelers is disclosed. The device has three gears: a forward gear, a neutral gear and a backing gear, the device adopts a three-star gear form, the direct meshing of the two gears is converted into the meshing by a middle gear through a gear shifting device, to shift the direction change of the output wheels, thereby reaching the purpose that the forward moving and the backward moving of the vehicle can be realized under the condition that the direction change of the main driving power is not changed. A gear positioning structure is installed at the gear shifting device, thereby enabling the backing device not to generate the gear slip phenomenon. All transmission gears of the device are installed in a compression cast aluminum box, which can be used as an independent body to be installed and used at any situation requiring direction change with good dustproof performance.
Description
Technical field
The present invention is a kind of backing device for minitype quadricycle
Background technique
The traffic tool play an important role in the national economic development, and along with the development and the multiple demands of people's lives, also popularizing of miniature four-wheel vehicle will become a part of human needs.Travelling of miniature four-wheel vehicle needs car-backing function equally from driving functions, and drive like this and get up just can have to reverse end for end to turn to flexibly function, and with the driving interest that drives a car the same.But search from present data, do not find that as yet simple and easy miniature four-wheel vehicle has car-backing function, therefore designing a kind of simple light mini-type four-wheel vehicle backing device is purpose of the present invention.
Summary of the invention
The invention reside in small and exquisite, the simple in structure backing device that is applicable to miniature four-wheel vehicle of a kind of volume of design.This device has forward gear, neutral gear and three gears of reverse gear shift, this device adopts the tumbler gear form, be converted to through the intermediate gear engagement by the direct engagement of gearshift two gears, turning to of conversion output wheel, thus reach the main purpose that the vehicle realization moves forward and backward under the constant situation of servosteering that drives.Gearshift is equipped with the gear position structure, thereby makes this backing device can not produce the gear slip phenomenon.This device driving gear all is installed in the die casting aluminium box, and anti-dust performance is good, and can be used as an independent integral body, installs and uses in other any occasion that needs commutation.
Description of drawings
Accompanying drawing 1 backing device external form figure
Accompanying drawing 2 backing device structural drawing
Among the figure
1. gear shifting handle 2. reversing plates 3. intermediate gears 4. main drive gears 5. pairs drive wheel disc 6. auxiliary driving gears 7. flywheels 8. spring stops 9. gear fixed plates 10. gear-boxes 11. gear box covers
Embodiment
With the rotational power of foot-driven wheel disc or direct current generator through chain transmission to backing device flywheel (7), the main drive gear (4) coaxial with flywheel (7) rotates simultaneously, when gear shifting handle (1) during in neutral position, intermediate gear (3) and auxiliary driving gear (6) all break away from main drive gear (4), the power no-output.
When gear shifting handle (1) when advancing gear, intermediate gear (3) and main drive gear (4) engagement, drive auxiliary driving gear (6) through intermediate gear (3) and rotate, the pair driving wheel disc (5) coaxial with auxiliary driving gear (6) rotates in the same way, advances through chain transmission to main driving wheel.
3. when gear shifting handle (1) during at backing car gear, auxiliary driving gear (6) directly meshes rotation with main drive gear (4), direction is with preceding opposite, and the pair coaxial with auxiliary driving gear (6) drives wheel disc (5) backward rotation simultaneously, through chain transmission to main driving wheel vehicle rollback.
4. for preventing that this device of gear slippage is provided with the gear positioning device, the fixing pin of gear fixed plate (9) end inserts in the positioning hole on gear-box (10) top, its back is lived by the spring bullet that is contained on the spring stop (8), during gear shift with gear shifting handle (1) to the extrapolation or to pressing down an angle, make the gear fixed plate (9) of fixedlying connected break away from positioning hole, rotate gear shifting handle (1) again and carry out gear-change operation with it.
Claims (4)
1. backing device for minitype quadricycle has forward gear, neutral gear, reverse gear shift function and by aluminum alloy casing and inner tumbler gear with commutation function, the outside has the gear shifting handle of gear positioning device and forms.
2. according to the backing device for minitype quadricycle of claim 1, tumbler gear adopts main drive gear to fix, auxiliary driving gear and intermediate gear are installed on the reversing plate respectively the mode with the main drive gear engagement, also can conceive the number of teeth that changes gear in view of the above, change the speed ratio of gear-box.
3. according to the backing device of claim 1, have the locking device of anti-gear slippage, its gear fixed plate is to be fixed together with gear shifting handle, and device simultaneously unlocks during gear shift.
4. according to the backing device for minitype quadricycle of claim 1, the top that is designed to of its gearbox-case has the positioning hole device.
