Background technology
Currently, the variable part technology of multi-speed bicycle application is old, although there are many new technology, have various
The shortcomings that being difficult to overcome.
Invention content
The present invention is in view of the shortcomings of the prior art, provide a kind of small-sized, independence for being suitble to use on bicycle, multistage closing
Without blockchain bevel gear speed changer.
The technical solution that the present invention solves above-mentioned technical problem is as follows：Bevel gear speed changer, mainly by wheel disc, bevel gear
Circle, suspension bevel gear piece, input shaft, output shaft, shift fork, inside and outside hub splines, unilateral thrust radial ball bearing and casing composition；
Bevel gear circle is separately fixed at each of sheave surface and goes in ring on step；Inside and outside hub splines is set on the output shaft, and suspend cone tooth
Wheel piece is sleeved on inside and outside hub splines, is used between the piece and piece of suspension bevel gear piece, between outer lateral suspension bevel gear piece and casing
Unilateral thrust radial ball bearing supports；Inside and outside splined shaft is cased with inside and outside two kinds of splines, the internal spline of inside and outside hub splines and defeated
The external splines of shaft engages always, is cooperation between the two, the external splines of inside and outside hub splines and suspension bevel gear piece it is interior
Spline is that cooperation, inside and outside hub splines axially move between output shaft and suspension bevel gear piece；When converting gear, shift fork
Inside and outside hub splines is pushed into designated position, the interior flower of the external splines of inside and outside hub splines and selected monolithic suspension bevel gear piece
Key engages；Bevel gear circle and mutual corresponding suspension bevel gear piece remain meshing state, are quiet between wheel disc and input shaft
Cooperation, bevel gear circle and suspension bevel gear piece occur in pairs, can increase and decrease their logarithm as needed.
The beneficial effects of the invention are as follows：Suspension spur gear is improved to suspension bevel gear, is made in gear-shift mechanism for the first time
Coordinated with bevel gear circle and suspension bevel gear.This change is economical and practical, with the obvious advantage, such as：1, the structure of speed changer is simply closed
It manages and volume is made to further reduce；2, the transmission efficiency of speed changer is greatly improved.

Specific implementation mode
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
Bevel gear speed changer, by 1, three bevel gear circle (1-1,2,3) of wheel disc, three suspension bevel gear pieces (2-1,2,3),
Inside and outside hub splines 6, unilateral thrust radial ball bearing 7, input shaft 3, output shaft 4 and shift fork 5 form.Unilateral thrust radial ball axis
Each suspension bevel gear piece (2-1,2,3) of 7 supports is held to suspend alone rotation.Shell 8 is supported by unilateral thrust radial ball bearing 7
Outer lateral suspension bevel gear piece (2-1,3) rotation.There is sufficient space between output shaft 4 and each suspension bevel gear piece (2-1,2,3)
Inside and outside hub splines 6 is allowed to axially move wherein.When needing speed change, inside and outside hub splines 6 is pushed specific bit by shift fork 5
It sets, inside and outside hub splines 6 meshes together certain piece suspension bevel gear piece (2-1,2,3) and output shaft 4, plays the work of clutch
With.Each bevel gear circle (1-1,2,3) and corresponding a piece of suspension bevel gear piece 2-1,2,3 permanent retention engage shape in pairs
State.How many is to boring gear ring (1-1,2,3) and suspension bevel gear piece (2-1,2,3) with regard to how many in a bevel gear speed changer
Grade speed change.The axis and rear axle of each bicycle each must be equipped with a bevel gear speed changer, two bevel gear speed changers
4 direct connection of output shaft.The speed change gear number of bicycle is the product of two bevel gear speed changer series.
With reference to each figure, the present invention is mainly by wheel disc 1, bevel gear circle (1-1,2,3), suspension bevel gear piece (2-1,2,3), defeated
Enter axis 3, output shaft 4, shift fork 5, inside and outside hub splines 6, unilateral thrust radial ball bearing 7 and casing 8 to form.Inside and outside hub splines
6 are sleeved on output shaft 4.Suspension bevel gear piece (2-1,2,3) is sleeved on inside and outside hub splines 6.Suspension bevel gear piece (2-1,2,3)
Piece and piece between, outside suspension gear piece (2-1,3) supports between casing 8 with unilateral thrust radial ball bearing 7.It suspends
Bevel gear piece (2-1,2,3) has sufficient space to allow inside and outside hub splines 6 in output shaft 4 and suspension gear piece between output shaft 4
It axially moves between (2-1,2,3).When needing speed change, inside and outside hub splines 6 is pushed designated position, inside and outside flower by shift fork 5
Key axle sleeve 6 meshes together certain piece suspension bevel gear piece (2-1,2,3) and output shaft 4.Inside and outside hub splines 6 therefrom play from
The effect of clutch.
It is stationary fit between wheel disc 1 and input shaft 3 referring to Fig. 1, Fig. 2.Each bevel gear circle (1-1,2,3) and corresponding
The pairs of meshing state of a piece of suspension bevel gear piece (2-1,2,3) permanent retention, how many is to regard to how many grade gear speed change.
The bevel gear speed changer that the axis of bicycle and rear axle want one no-load voltage ratio of each installation different in actual use, the gear level of bicycle
Number is the product of two bevel gear speed changer series.
Referring to Fig. 1, the present invention is combined using three pairs of bevel gear circles (1-1,2,3) with suspension bevel gear piece (2-1,2,3).Such as
Fruit is identical by two such number of steps of speeds but the different bevel gear speed changer of no-load voltage ratio is mounted on bicycle, the bicycle
Speed change gear should be nine grades.As long as increasing and decreasing bevel gear circle (1-1,2,3) and the logarithm of suspension bevel gear piece (2-1,2,3) and more
Change their the no-load voltage ratio i.e. gear stages of changeable bicycle.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention.The present invention can also be used in
Automobile or other mechanical speed change occasions, as long as series is more than enough, so that it may to achieve the effect that electrodeless variable-speed.All spirit in the present invention
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
