Description
Technical field
Field of vehicles is the utility model is related to, more specifically, more particularly to a kind of speed changer and bicycle.
Background technology
Bicycle (bicycle) is also known as bicycle or bicycle, the small-sized ground vehicles of typically two wheels, is that modern people are normal
A kind of environmental type vehicles.In modern society, bicycle turns into countries in the world particularly developed country resident
The traffic liked, fitness tool.Meanwhile the center of gravity of world's bicycle trade is also from traditional type vehicles of riding instead of walk to motion
Type, mountain, leisure type transformation, in U.S., Europe, Deng developed countries, bicycle is even more to become a kind of universal motion, be good for
Body, leisure and recreational product.
When bicycle advances, cycling staff pedals foot-operated rotation, and pedal drive nipper disc spins, preceding fluted disc passes through chain handle
Strength is relayed to rear tooth disk, rear tooth disk and then is rotationally advancing with motor car wheel.When bicycle moves ahead, the size (number of teeth) of preceding fluted disc and
The size (number of teeth) of rear tooth disk determines to pedal dynamics when riding, it is however generally that, preceding fluted disc is bigger, and rear tooth disk is smaller, during pedal
More feel laborious；Preceding fluted disc is smaller, and rear tooth disk is bigger, more feels relief during pedal.In practical operation, for make bicycle quickly with
Certain pedal leg speed and torque can be kept by advancing at a slow speed, it is often necessary to speed changer is installed on bicycle.Speed changer principle
Coordinated by changing chain from the toothed disc of different forward and backward sizes so as to change speed speed.
Fig. 1 provides a kind of existing speed changer, as shown in figure 1, the speed changer includes control sleeve 01, clutch 02
With planet carrier 03, control sleeve 01, clutch 02, planet carrier 03 are sleeved on axis 04, and control sleeve 01 is shifted gears with outside
Device is connected, and planet carrier 03 is connected with wheel.During gearshift, cycling staff rotation forces control sleeve 01 and then pushes away control sleeve 01
Dynamic clutch 02 moves to the direction of planet carrier 03, when clutch 02 and the projection 020 and groove 030 of 03 corresponding end face of planet carrier
Inlay card together when, clutch 02 and planet carrier 03 can be linked with realizing, successfully be shifted gears successfully so as to realize.Practical operation
In, before gearshift, under normal riding condition, cycling staff is pedaled the foot-operated planet carrier 03 that passes through and rotated with motor car wheel, in this way, ought be voluntarily
During car parking gearshift, projection 020 is possible to be not in the position of face with groove 030, and now, projection 020 can be expert at even at the cost of one's life
So as to cause projection 020 to cannot be introduced into groove 030 on the end face of carrier 03, so cause selector rotation forces stroke by
Limit, causes selector can not be pushed to defined gear, and so as to cause gearshift to fail, significantly impacting the normal of bicycle makes
With.

, clamp 7 can use ring-type clamp, and annular groove is set on the inwall of clutch 3, then be arranged on ring-type clamp in annular groove i.e.
Can.
In the present embodiment, the thrust that outside selector transmission comes is transferred to telescoping mechanism to further facilitate application cylinder 4
6, it is preferable that be provided with packing ring 8 between the telescoping mechanism 6 and the application cylinder 4.
In the present embodiment, thrust is transferred to application cylinder 4 to further facilitate peripheral hardware selector, it is preferable that the control
Control-rod 9 is connected with cylinder 4.Hole body is provided with the application cylinder 4, card body is provided with the control-rod 9, the card body is embedding
In the hole body.In specific implementation, control-rod 9 links together with peripheral hardware selector, when selector acts, can promote
Control-rod 9 slides together along the slip of the axis direction of main shaft 1, control-rod 9 and then drive application cylinder 4.
In the present embodiment, the separation of clutch 3 and planet carrier 2 when moving back gear for convenience of selector, it is preferable that the main shaft 1
External cylindrical surface on be provided with land 101, the land 101 is located at the front end of clutch 3, the land 101 with it is described from
Back-moving spring 10 is provided between clutch 3.
In the present embodiment, it is contemplated that stop under grade state, foot-operated stop orientation is not handy just at cycling staff
The position of power, now, cycling staff usually need to control foot-operated reversion certain angle, so that foot-operated, to turn to cycling staff good
The position puted forth effort, now, the remains stationary typically together with wheel of planet carrier 2, in this way, foot-operated anti-for convenience of cycling staff control
Turn, it is preferable that corresponding between the projection 301 and the neck 201 to be provided with reversion export inclined-plane 11.In this way, cyclist
When reversion is ridden in member's control, together clutch 3 can be driven to invert together, now, projection 301 can be with along reversion export inclined-plane
11 skid off out of neck 201, so as to realize the separation between clutch 3 and planet carrier 2, clutch 3 is individually rotated.
That is, when being stepped on after gearshift completely, clutch 3 reversely rotates, and clutch 3 can reversely export along planet carrier 2
Inclined-plane 11 exits vertically, by compressing buffer spring, without influenceing application cylinder 4.
