Abstract
Disclosed is a chainless gearing speed changing device for bicycles. A side tooth basin is respectively fixed to the rear axle and the middle axle; each side tooth basin is provided with at least a circle of gear teeth; each side tooth basin is engaged with the gear of a straight shaft by the gear teeth. The speed changing device for bicycles makes use of the gear of the straight shaft to change speed, and the gear is shifted by a mechanical device. The utility model has the advantages of simple structure, and convenient speed changing, and has a little change to the structure of the bicycle.
Description
The utility model relates to the transmission system on a kind of Chainless bicycle.
At present the bicycle speed-varying unit that uses all is to be applied on the chain-type bicycle, and such change-speed box is the gear driving bicycle that can not be applicable to no chain.In order to address this problem, people imagine to the many ways to gear of bicycle installation usually, but bicycle is very heavy like this, and speed-changing mechanism damages easily.90211608.8 of Chinese patents have proposed the bicycle coaxial speed variator, though solved the problems referred to above, its complex structure is bigger to the change of ordinary bicycle, so this invention is difficult to implement.
The purpose of this utility model provides a kind of no chain-type derailleur that overcomes above-mentioned shortcoming, and it is the speed of conversion bicycle effectively and simply.
The purpose of this utility model is achieved in that installs a d-axis between the axis of gear wheel bicycle and rear axle, d-axis is fixed on the bicycle, and rotatable.Connect a gear respectively at the d-axis two ends, gear adopts circumferentially fixing.On axis and rear axle, consolidate a limit chain wheel simultaneously respectively.So-called limit chain wheel is a garden dish, and its side has a circle or some circles to be the teeth that concentric garden distributes.The limit chain wheel is by the gear mesh on these teeth and the d-axis.Be meshed with gear on the d-axis by the limit chain wheel on axis and the rear axle like this, the rotating torque of axis is passed to rear axle, bicycle is advanced.Gear on the d-axis makes it do local the slip vertically then by mechanical device control, thus the speed of regulating bicycle.
The utility model is owing to only change common gear into the limit chain wheel on gear wheel bicycle, thereby it is simple in structure; An end only adopts a gear speed governing on d-axis, and change speed is very convenient, good stability; Simultaneously, minimum to common bicycle structure change, so have very high practical value, be worthy of popularization.
The utility model is described in further detail below in conjunction with embodiment.
Fig. 1 is a scheme drawing of the present utility model;
Fig. 2 is the mechanical device section-drawing to pinion;
Fig. 3 is the front elevation of limit chain wheel.
As shown in Figure 1, on the axis (1) of bicycle and rear axle (3), a limit chain wheel (4) is installed respectively, these two limit chain wheels (4) are installed in the same side of bicycle, and limit chain wheel (4) one side (hereinafter referred to as the front) that teeth (6) are arranged is towards on the contrary.The no conical surface of the positive employing of limit chain wheel (4).D-axis (2) two ends between two limit chain wheels (4) have a gear (5) respectively.As shown in Figure 2, this gear (5) is the garden stud wheel, adopts circumferentially to be fixed on the d-axis (2).There is a U-shaped recess (8) in gear (5) outside, the contacts side surfaces of the inboard of recess (8) and gear (5), and pinion (5) slides.U-shaped recess (8) can along with the parallel direction translational of d-axis (2), its top is connected with speed-changing mechanism with connecting rod (9) by spring (7).
As shown in Figure 3, the teeth (6) on the limit chain wheel (4) can be selected shapes such as hemisphere or cone for use.Garden stud wheel (5) facewidth on the d-axis (2) is 1 to 3 times of teeth (6) width on the limit chain wheel (4) that is engaged with, like this when gear (5) and limit chain wheel (4) when making engaged transmission, can overcome the deviation that causes because of reasons such as bicycle vibrations, improve stability of transmission.Requiring limit chain wheel (4) to go up distance between the two adjacent rings teeth (6) simultaneously is 1 to 2 times of gear (5) width on the d-axis (2), when bicycle needs speed change, U-shaped recess (8) is stirred by connecting rod (9) and spring (7) by variable speed control mechanism, gear (5) is slid into earlier in the neutral gear between limit chain wheel (4) the two adjacent rings teeth (6), and then enclose teeth (6) with another and mesh, reach the purpose of speed change.
Claims (7)
1, a kind of bicycle does not have the chain gear change-speed box; This change-speed box has a d-axis (2) between bicycle middle shaft (1) and rear axle (3), d-axis (2) two ends connect a gear (5) respectively, and gear (5) adopts circumferentially fixing, it is characterized in that:
(a) fix a limit chain wheel (4) respectively on axis (1) and the rear axle (3), have a circle or some circles to be the teeth (6) that concentric garden distributes on the side of limit chain wheel (4), limit chain wheel (4) is by the engagement of the gear (5) on these teeth (6) and the d-axis (2);
(b) gear (5) slip vertically on the d-axis (2) is controlled by a mechanical device.
2, change-speed box according to claim 1, it is characterized in that the mechanical device that pinion (5) slides is a U-shaped recess (8), its contacts side surfaces inboard and gear (5), U-shaped recess (8) can along with the parallel direction translational of d-axis (2), and its top is connected with variable speed control mechanism by spring (7).
3, change-speed box according to claim 1 and 2 is characterized in that it is the garden conical surface that limit chain wheel (4) is gone up the surface of distribution teeth (6).
4, change-speed box according to claim 1 and 2 is characterized in that the teeth (6) on the limit chain wheel (4) are shaped as cone or hemisphere.
5, change-speed box according to claim 3 is characterized in that the teeth (6) on the limit chain wheel (4) are shaped as cone or hemisphere.
6, change-speed box according to claim 1 and 2 is characterized in that the gear (5) on the d-axis (2) is the garden stud wheel, and its facewidth is 1 to 3 times of teeth (6) width on the limit chain wheel (4) that is engaged with.
7, change-speed box according to claim 6 is characterized in that it is 1 to 2 times of gear (5) width on the d-axis (2) that limit chain wheel (4) is gone up distance between the two adjacent rings teeth (6).
