Description
Technical field
The present invention relates to gear-shift mechanism, splined shaft gear selecting bevel gear speed changer and a kind of bicycle speed-varying unit.
Background technology
There is multigroup gear on each axis in two axis or triple axle gearbox, to form different gearratios and possible turn
Direction is moved, generally there is multiple combined covers or shifting slide gear in gearbox, selector fork stirs combined cover or shifting slide gear, changes and becomes
Gear engagement position in fast case carries out speed change or commutation.Two axis or three shaft gearbox are complicated, and volume is big, and weight is big, energy
Applied on automobile, it is difficult to be applied on bicycle.The structure of two axis or three shaft gearbox is how reduced, saves combined cover, is subtracted
The gear of few half quantity, replaces multiple selector forks with a gearshift mechanism, gearbox volume and weight is greatly reduced, will
It is applied on bicycle, motorcycle and some other light-duty machinery, is to have the problem of to be solved.
The content of the invention
In view of said circumstances, it is an object of the invention to provide splined shaft gear selecting bevel gear speed changers and a kind of bicycle to become
Fast device.Compared with two axis or triple axle gearbox, the number of structures of the speed changer is greatly reduced the speed changer, does not tie
Trap, gear quantity reduce half, multiple selector forks are replaced with a gearshift mechanism.The speed changer structure is extremely simple,
It is small, it is light-weight, it is suitably applied on bicycle, on motorcycle and some other light-duty machinery.
Realizing the splined shaft gear selecting bevel gear speed changer and a kind of technical solution of bicycle speed-varying unit is：The speed change
Device is mainly by a multi-turn wheel bevel gear in first axle, the second axis, first axle, multiple bevel gears on the second axis, gear shift
Pulling axis is pitched and transmission case composition.
Speed changer has two vertical concurrent aceses, first axle and the second axis.There are one be fixed as one with axis for set in first axle
The multi-turn gear teeth are distributed in the multi-turn wheel bevel gear of body, the one side of multi-turn wheel bevel gear, and each circle gear teeth form a gear ring,
For each gear ring using gear axis as the center of circle, radius is different, and each gear ring is functionally equivalent to a bevel gear, the multi-turn gear teeth
Bevel gear can be regarded as the different bevel gear of multiple radiuses and coaxially be nested together what is formed.Second axis can move vertically
It is dynamic, multiple bevel gears are cased with thereon, and each bevel gear can rotate but cannot be axially moveable on axis.Each cone on second axis
Gear engages respectively with each gear ring of first axle gear, forms a variety of gearratios and rotation direction and is selected for gear shift.Second
In the middle part of axis certain it is a bit of have prominent external splines, and rest part is smooth does not have external splines.The each cone tooth being sleeved on the second axis
There is internal spline in wheel center, and each internal spline can couple with the external splines of the second axis.It is each on the second axis during transmission duty
The velocity of rotation of bevel gear is different with rotation direction.One section of specific range of the second axis is axially moveable, when smooth on the second axis
When part is directed at the internal spline of each bevel gear thereon, each bevel gear is dallied on the second axis, and speed changer is in neutral gear.Along axis
To mobile second axis certain distance, the external splines on the second axis is deep into the internal spline of a bevel gear on the second axis, the
Two axis rotate together with the bevel gear, and the smooth part on the second axis is directed at the internal spline of remaining bevel gear, remaining bevel gear
It dallies on the second axis, i.e., the second axis has only coupled a bevel gear at this time, and speed changer selects the gearratio that the bevel gear participates in
And rotation direction.Similarly, be axially moveable the second axis different specific range, the external splines of the second axis respectively from it is different thereon
Bevel gear internal spline connection, speed changer selects the gearratio and rotation direction that different bevel gears participate in.The speed changer
Power transfer path is：First axle, gear ring, the bevel gear of gear ring engagement, the internal spline of bevel gear, the external splines of the second axis, the
Two axis；Power transfer path can also be：Second axis, the external splines of the second axis, the internal spline of bevel gear, bevel gear, bevel gear
The gear ring of engagement, first axle.
Along the circle of axial plane one there are one annular groove, the fork of gear shift pulling axis fork is stuck in annular groove, changes for second axis one end
The fork of shelves pulling axis fork is stuck in the rotation for not influencing the second axis in the annular groove of the second axis.Second can be made by stirring gear shift pulling axis fork
Axis is axially moveable different distances, so make the second axis selectivity couple or make with some bevel gear the second axis not with respectively
A bevel gear connection.
The multi-turn wheel bevel gear of first axle integrally substantially present it is discoid or bowl-shape, if substantially present it is discoid,
The gear ring of each different radii is substantially distributed in the plane of multi-turn wheel bevel gear place, the second axis that each gear ring is engaged
The radius of bevel gear is identical；If bowl-shape, the gear ring distribution of each different radii is integrally substantially presented in multi-turn wheel bevel gear
On the inner wall of " bowl ", each gear ring of radius from big to small engages the bevel gear of radius from small to large respectively, is so increased by
The slewing range of the speed changer.
The external splines of second axis couples with the selection of the internal spline of bevel gear thereon not to be completed by synchronizer, and gear shift is easy
Mesh impact is generated, the speed changer can apply on bicycle, motorcycle and some other light-duty machinery.
The beneficial effects of the invention are as follows：
Compared with existing two axis or triple axle gearbox, the number of structures of the speed changer is greatly reduced, and is not bound with set,
Gear quantity reduces half, and multiple selector forks are replaced with a gear shift pulling axis fork.The speed changer structure is extremely simple, volume
It is small, it is light-weight, it is suitably applied on bicycle, motorcycle and some other light-duty machinery.Embodiment one is not bound with set, with five
A gear and gear shift pulling axis fork are with regard to that can complete neutral gear, one grade, two grades, the speed changes of third gear and reverse gear totally five gears.
