Abstract
The utility model relates to a rear axle mechanism of a tricycle, and has a component assembly in which the sprocket accepts motive power which is transmitted to the two rear wheel through the differential gear system. The utility model is used to solve the problem of the existing third wheel bias thrust.
Description
The utility model is as manual tricycle or light-duty motor-driven, electro-tricycle, the improvement structure of rear axle.
Manual tricycle or light-duty rear axle motor-driven, electro-tricycle be with two trailing wheels in one captive joint, become driving wheel, another bye cover play supporting role, tractive force be created in the biasing one side driving wheel on.Like this, concerning three-wheel vehicle, not only produced the tractive force that makes it to advance, also produced simultaneously and made the vertical axis rotating moment of car around self center of gravity.Just must produce a reciprocal moment comes the above-mentioned moment of balance for two other wheel and ground-surface contact point, just is unlikely the vertical axis rotation that car body is walked around center of gravity.Hence one can see that: the resistance that stops driving wheel to rotate is bigger, must with bigger power to pedal or bigger power driving wheel be rotated, and car advances.Relatively require great effort in other words, energy consumption is bigger in other words.
This problem does not cause people's attention, because use now is simple in structure really, makes easily, keeps in repair, but be to have increased the resistance of riding really yet.
The utility model provides axle construction behind a kind of three-wheel vehicle, not changing under the integrally-built situation of original car, only changes rear axle, just can address the above problem.
The three-wheel vehicle rear axle is that 18 is sprocket wheel as accompanying drawing, and the power that acceptance is transmitted by chain passes to differential gear train 14,11, passes to axle 1 via housing 16, little axle 15, has interior external key bonded assembly support sleeve 4 because nut 2 has compressed, thus the drive wheel.Housing 16 and dish 8 are used for brake, and two half-shells 7 of axle system are connected with 19 usefulness screws, and the seam location is arranged, so can guarantee with one heart.Have breach on the shell 19, so that chain and brake band are installed.Axle system can be divided into several specifications by size, to adapt to the three-wheel vehicle of different model.
The utility model be contained in use on the three-wheel vehicle laborsaving.As transportation means, laborsaving being critical.If be equipped with special tooling, just be easy to realize.
Claims (1)
- Three-wheel vehicle rear axle system comprises sprocket wheel, brake wheel, and differential gear train and transmission shaft is characterized in that:1, differential gear train, be installed in the centre of axle system, and in the cavity that brake wheel constitutes;2, an end of transmission shaft is the gear of differential gear train, or fixes with the gear of differential gear train, connects, and the other end is and wheel bonded assembly axle.
