Abstract
The utility model relates to a bicycle component, particularly a special speed-changing device for a bicycle. The device comprises a frame of the bicycle, a bicycle head, a braking device, a pedal, a drive sprocket, a front and a rear wheels and a ratchet mechanism, wherein, the rear wheel and the ratchet wheel are arranged on the same rear-wheel shaft. The utility model is characterized in that a speed-increasing device which is arranged on the rear-wheel shaft comprises a casing and an NGW wheel train mechanism with a moving shaft; a force arm of a planetary carrier inputs driving force into the utility model; after the driving force passes through a planetary wheel and a sun gear fixed on the rear-wheel shaft, the rear wheel of the bicycle is driven to rotate by an annular gear ring and a ratchet wheel. The utility model has the advantages of labor saving, simple structure, etc.
Description
The utility model relates to bicycle assembly parts, specifically a kind of transmission system that is exclusively used in bicycle.
Existing bicycle does not have the speed changing force-saving device mostly, and the transmission of its power sends ratchet by foot-operated sprocket wheel to through chain usually, drives trailing wheel again and whole bicycle advances, and its defective is harder.
The later-model purpose of this usefulness is that design a kind ofly can be saved the labour, the simple again bicycle speed increasing force saving device of structure.
Its main technical schemes comprises the vehicle frame of bicycle, headstock, brake gear, step and drive sprocket, front and back wheel and ratchet device, trailing wheel and ratchet are installed on the same hind axle, the feature of this patent is that a boost installation is installed on hind axle, in this device, there is a shell to utilize bearing installation respectively on bicycle rear, the two ends, the left and right sides of pinion carrier utilize the left side of bearing installation at wheel shaft, the fastening planet axis of the flange end of pinion carrier right-hand member, satellite gear utilizes the right-hand member of bearing installation in planet axis, the internal tooth ring support that internally toothed annulus is installed utilizes the middle part of bearing installation at hind axle, one sun gear is fastened on the hind axle, satellite gear meshes with internally toothed annulus and sun gear respectively, and the middle part of bicycle ratchet is installed in the right-hand member of internal tooth ring support, and the ratchet of ratchet outer rim is connected with the right-hand member of shell; Shell wherein is by the case shell and be connected a case shell left side, and the right lid of the case lid at right two ends and spoke constitutes, and described internally toothed annulus utilizes screw to be fastened on the inboard of internal tooth ring support left end, at the shaft-cup of the arranged outside dust-break of bearing.
The utility model has the advantages that owing on bicycle, utilize the less NGW dynamic gear train mechanism of transmission speed ratio to make variable-speed drive, improved the speed of a motor vehicle of bicycle, saved propulsive effort, make the rider by bike the time, feel lighter; Compare the change-speed box long service life of this patent, sanitation and hygiene with existing outer naked variable speed bicycle.
Fig. 1 is speed changer structure figure of the present utility model.
Fig. 2 is the bicycle structure figure that this patent change-speed box is installed.
Fig. 3 is the change-speed box schematic diagram.
As shown in Figure 1: shell is made of with the right lid 36 of spoke case shell 2 and the case lid 1 that is connected two ends, case shell 2 left and right sides with screw 20, the middle part of case lid 2 utilizes bearing 13 to be installed on the pinion carrier 3 and in the left side of bearing 13 back-up ring 14 and the shaft-cup that is installed on the case lid 1 is set, with location bearing and dust-break.The right-hand member of pinion carrier 3 has a planet boom, tighten a planet axis 15 at this arm, satellite gear 12 utilizes bearing 16 to be connected on the planet axis, packing ring 17,22 is placed in both sides at bearing 16, pinion carrier utilizes bearing 9,11 to be installed on the hind axle 32, place the packing ring 6,7 that is enclosed within on the hind axle in the both sides of two bearings 9,11 successively, and the back-up ring 10 that is installed on the pinion carrier 3 is set, move axially to avoid bearing to produce in the left side of bearing 9 and the right side branch of bearing 11.Tighten and satellite gear 12 ingear sun gears 5 at hind axle 32 corresponding to satellite gear 12, the right-hand member of one internal tooth ring support 21 utilizes bearing 26,28 to be installed on the hind axle 32, utilize screw 19 fastening internally toothed annuluss 18 in the left end inboard of this internal tooth ring support 21, satellite gear 12 and internally toothed annulus 18 engagements, bicycle ratchet 25 is installed in right-hand member outside at internal tooth ring support 21, and the ratchet of ratchet outer rim utilizes the right lid 36 of screw 24 and spoke to be connected.The middle part of the right lid 36 of spoke utilizes bearing 30 to be installed on the hind axle 32, packing ring 35,34 and the locating bush 33 that is enclosed within on the hind axle 32 arranged respectively on 26,28,30 on bearing, in the left side of bearing 28 and the right side of bearing 30 back-up ring 27,29 that is installed on internal tooth ring support 21 and the right lid 36 of spoke is arranged respectively, leak free shaft-cup 31 is installed in back-up ring 29 outsides.
