Abstract
The utility model discloses a gear-shift tricycle. For the gear-shift tricycle, a middle axle is connected with a gear-shift mechanism which is formed by that the middle axle is connected with a driving gear which is provided with a side face depression and internal teeth and can rotate on the middle axle, as well as a sliding gear which can slide on the middle axle; a wheel disc and the driving gear are fixedly connected together and can rotate on the middle axle, the wheel disc and the driving gear are fixedly connected together, the sliding gear is formed by that a main gear is connected with a pinion through a positioning sleeve, and the positioning sleeve is internally provided with a spring and a steel bead; a gear lever is arranged between the main gear and the pinion; the driving gear is meshed with a transmission gear; and the transmission gear, a low-speed gear and a high-speed gear are fixedly connected together with an auxiliary axle. The sliding gear can slide on the middle axle and is meshed with a change gear, thus realizing gear-shift riding. The gear-shift tricycle is suitable for being used as a cycle rickshaw for transporting goods in the countryside.
Description
Technical field
The utility model relates to a kind of manual tricycle.
Background technology
Known three-wheel vehicle connects railway carriage, front-wheel, trailing wheel by vehicle frame and constitutes, and the vehicle frame middle part is connected with drivings device such as pin turns, wheel disc, chain.The driving device of this car does not have speed-changing mechanism, thereby does not have speed changing function.At at full load, the effort of riding; When zero load, speed is too slow again.
Summary of the invention
The purpose of this utility model is that a kind of speed change three-wheel vehicle will be provided, and this three-wheel vehicle can speed change, and at full load, it is laborsaving to ride; When zero load, speed is very fast.
The purpose of this utility model is achieved in that the vehicle frame rear portion of this speed change three-wheel vehicle is connected with railway carriage and trailing wheel, the vehicle frame front end is connected with front-wheel, the vehicle frame front portion is connected with axis, axis is connected with wheel disc and pin turns, axis also is connected with speed-changing mechanism, described speed-changing mechanism is that axis is connected with side-facing depressions and internal tooth is arranged and can be at the driven wheel that rotates on the axis and the cliding gear that can slide on axis, wheel disc and driven wheel are fixed together and can rotate on axis, cliding gear is connected with miniature gears by big gear wheel by locating bush, spring and steel ball are housed in the locating bush to be constituted, between big gear wheel and the miniature gears shifter bar is arranged, driven wheel is meshed with transmission gear, transmission gear, low speed gear and high speed gear and countershaft are fixed together.
Cliding gear of the present utility model can slide on axis, meshes with each variable gear, drives trailing wheel by wheel disc and chain again, realizes that the speed change of manual tricycle is ridden.The three-wheel vehicle at full load, it is laborsaving to ride; When unloaded, speed is very fast.Being particularly suitable for the rural area uses as the manual tricycle that conveys goods.
Below in conjunction with the drawings and the specific embodiments the utility model is elaborated.
Description of drawings
Fig. 1 is a specific embodiment structural representation of the present utility model.
Fig. 2 is the speed-changing mechanism scheme drawing among Fig. 1.
1. vehicle frames among the figure, 2. shifter bar, 3. pin turn, 4. speed-changing mechanism, 5. wheel disc, 6. chain, 7. housing, 8. big gear wheel, 9. axis, 10. positioning groove, 11. high speed gears, 12. countershafts, 13. low speed gears, 14. transmission gears, 15. driven wheels, 16. miniature gearss, 17. steel balls, 18. springs.
The specific embodiment
In Fig. 1, vehicle frame 1 rear portion is connected with railway carriage and trailing wheel, and vehicle frame 1 front end is connected with front-wheel.Vehicle frame 1 front portion is connected with axis 9, and axis 9 is connected with wheel disc 5 and pin turns 3.Axis 9 also is connected with speed-changing mechanism 4.
In Fig. 2, described speed-changing mechanism 4 is that axis 9 is connected with side-facing depressions and internal tooth is arranged and can be at driven wheel 15 that rotates on the axis 9 and the cliding gear that can slide on axis 9.Wheel disc 5 is fixed together and can rotates on axis 9 with driven wheel 15.Cliding gear is connected with by locating bush by big gear wheel 8 and in miniature gears 16, the locating bush spring 18 is housed and steel ball 17 constitutes, between big gear wheel 8 and the miniature gears 16 shifter bar 2 is arranged, driven wheel 15 is meshed with transmission gear 14, and transmission gear 14, low speed gear 13 and high speed gear 11 are fixedly connected with together with countershaft 12.
The concave surface that is positioned at driven wheel 15 when the miniature gears 16 of cliding gear is during with internal gearing, and pin turns 3 and directly drives trailing wheels by axis 9, miniature gears 16, driven wheel 15 and wheel disc 5 and chain 6, and three-wheel vehicle is to drive at moderate speed.
When shifter bar 2 is stirred big gear wheel 8 left, the concave surface that miniature gears 16 just withdraws from driven wheel 15 separates with internal tooth, directly be meshed with low speed gear 13, pin turns 3 miniature gears 16, low speed gear 13, countershaft 12, driven wheel 15 and wheel disc 5 and chains 6 by axis 9, cliding gear and drives trailing wheel, three-wheel vehicle is with low speed driving, it is laborsaving to ride, and is suitable at full load and rides.
When shifter bar 2 continues big gear wheel 8 to stir left, miniature gears 16 separates with low speed gear 13, big gear wheel 8 just is meshed with high speed gear 11, pin turns 3 by axis 9, big gear wheel 8, countershaft 12, transmission gear 14, driven wheel 15 and wheel disc 5 and chain 6 drive trailing wheels, the three-wheel vehicle at high speed travels, and rides when being suitable for zero load.
