Abstract
The utility model relates to a power transmission for bicycle with two different power sources as characteristics, in particular to a power transmission which is adapted for power-assisted bicycle. The utility model is characterized in that a support shaft sleeve is arranged on one end of the backshaft assembly, and the driving sleeve is fixed on the support shaft sleeve and in the casing by the bearing. One end of the driving sleeve couples with the driven gear using a ratchet mechanism, and the other end couples with the wheel hub using a terminal chain. The casing is fixed on the rear shaft of the bicycle through the support shaft sleeve, the rear bicycle fork and the rear shaft. The utility model has the advantages of compact conformation and convenient repair, and it is easy to be installed on common bicycle to use.
Description
The utility model relates to bicycle to use the torque transfer of two different dynamic sources as characteristics, particularly a kind of torque transfer that is applicable to morpet.
As everyone knows, existing combustion engine powered output is with the torque transfer of the morpet of shaft drive mode, generally adopt the torque transfer of the SACHS301/A type morpet of West Germany's production, its structure is that driven gear is installed in car rear axle centre portion through two needle bearings, drive sleeve one end adopts ratchet device to connect with driven gear, the wheel hub of the other end and wheel adopts splined, its weak point is that structure is not compact, maintenance is inconvenient, use purpose made car rear axle and purpose made solid wheel, be not easy to be installed on the ordinary bicycle and use.
The purpose of this utility model provides a kind of compact conformation, easy to maintenance with regard to being to overcome the deficiencies in the prior art part, is easy to be installed in the morpet torque transfer that uses on the ordinary bicycle.
For achieving the above object, feature of the present utility model is to be provided with supporting sleeve at rear axle assembly for bicycle one end, drive sleeve through bearing fixing on supporting sleeve and casing in, drive sleeve one end adopts ratchet device to connect with driven gear, the drive sleeve other end and wheel hub adopt the end key connecting, and housing is fixed on the car rear axle through supporting sleeve, rear vehicle fork and hind axle assembly.
The utility model makes morpet torque transfer compact conformation, easy to maintenance owing to adopt supporting sleeve, drive sleeve mouth and wheel hub to adopt the end key connecting, is easily installed on the ordinary bicycle and uses.
Description of drawings:
Accompanying drawing 1 is a scheme drawing of the present utility model, also is the scheme drawing of a kind of embodiment.
Mark in the accompanying drawing 1 is: driving gear 1, driving engine 2, driven gear 3, rear vehicle fork 4, axle assembly 5, supporting sleeve 6, bearing 7, drive sleeve 8, housing 9, bearing 10, wheel hub 11, sprocket wheel 12.
1 couple of embodiment of the present utility model is described further below in conjunction with accompanying drawing, rear axle assembly for bicycle 5 left ends are provided with supporting sleeve 6, supporting sleeve 6 is pressed against on the step on the hind axle assembly 5 by rear vehicle fork 4, drive sleeve 8 is fixed on the supporting sleeve 6 and in the housing 9 through two needle bearings 7,10, drive sleeve 8 one ends adopt ratchet device to connect with driven gear 3, the other end and wheel hub 11 adopt the end key connecting, and housing 9 is fixed on the car rear axle through supporting sleeve 6, rear vehicle fork 4 and hind axle assembly 5.During use, when driving engine 2 work, driving gear 1 drives driven gear 3 rotations, and driven gear 3 drives drive sleeve 8 rotations through ratchet device, and drive sleeve 8 drives wheel hub 11 rotations through the end key of its mouth, advances to drive bicycle; When driving engine 2 is not worked, drive bicycle by manpower, drive wheel hub 11 rotations through chain, sprocket wheel 12 and advance to drive bicycle, wheel hub 11 drives drive sleeve 8 rotations at this moment, because drive sleeve 8 adopts ratchet device to connect with driven gear 3, driven gear 3 does not rotate.
