Problems solved by technology

[0005] However, the most obvious problem with the above-mentioned transmission devices is that they all require the rider to manually adjust the speed. Changing gears, and often changing the wrong gear or changing the gear that is not what you want when changing gears, you need to change gears several times, which is relatively troublesome in actual operation

Embodiment 1

[0039] The technical solution described in the present invention is the first type of automatic transmission device. When the speed change slider unit 16 moves from the maximum speed difference state to the minimum speed difference state during use, the movement conditions between the various components are as follows:

[0040] When the first slide block 7 arrived at the minimum circumferential position, the second slide block 6 was at the maximum circumferential position, and now the speed change slider unit 16 was in the maximum speed difference state, that is, the linear velocity difference of the two slide blocks was the largest, and at this moment for the drive It is the most strenuous for the device, and the movable spacer wheel 11 is in the minimum position. In order to save effort, when the linear speed of the active chain 12 decreases, the speed of the slider wheel 17 also slows down, the centrifugal force difference of the sliders becomes smaller, the second slider 6 ...

Embodiment 2

[0044] Such as image 3 Each of the variable-speed rotary vane units 16' on the rotary vane wheel 17' includes a rotary vane 23 that is rotatably connected to the central bearing 2' through a rotary joint 22. The outer side of the rotary vane 23 is provided with a spring buckle 2301, and the inner side There is a groove 2302, and the spring 5 connects the groove 2302 to the spring buckle 2301 of another blade 23, and the other end of the blade 23 corresponding to the end connected to the rotary joint 22 is provided with a buckle sprocket 20' , the outer edge of the fixed wheel 1' is provided with a drive chain sprocket 21', the drive chain 12' is interlocked with the drive chain sprocket 21' on the fixed wheel 1', and the driving device 13' passes through the drive chain 12 'Drive the fixed wheel 1' to rotate, and the rotating fixed wheel 1' takes the center bearing 2' as the center of the circle to drive the rotary vane wheel 17' to rotate through the rotary switch joint 22, ...

Embodiment 3

[0049] Propose further embodiment three on the basis of embodiment one, two, as Figure 5 Shown this embodiment and embodiment one, two differences are:

[0050] Such as Figure 5 As shown, the fixed wheel 1" in this embodiment is composed of the fixed wheel 1 of the first embodiment and the fixed wheel 1' of the second embodiment superimposed and fixed on the same axis, and the active chain 12" is linked with the slider 7". The driven chain 14 "is linked with the buckle sprocket 20" on the impeller 17 "; the fixed wheel 1 in the first embodiment is no longer linked with the driven chain 14 ", and the fixed wheel 1' is no longer linked with the driven chain 14 in the second embodiment. Active with 12" link.

[0051] Other similarities between this embodiment and Embodiment 2 will not be repeated here.

[0052] To sum up, the centrifugal automatic transmission device of the present invention, through the change of the centrifugal force on the variable-speed rotary vane unit ...

Abstract

The invention relates to a centrifugal automatic speed change gear. The centrifugal automatic speed change gear comprises a speed change wheel body, a driving chain connected with a driving device, and a driven chain connected with a driven device. The speed change wheel body is composed of a sliding block wheel, a fixed wheel and center bearings penetrating through the axis of the sliding block wheel and the axis of the fixed wheel. The sliding block wheel is composed of multiple sliding blocks arranged on the same circumference in a radial mode with the center bearings as the center of a circle and whelps on the corresponding sliding blocks. The driving chain is buckled with the whelps on the sliding block wheel, the driving device drives the sliding block wheel to rotate through the driving chain, and due to the effect of centrifugal force, the diameter of the sliding block wheel is automatically changed along with the change of the rotating speed of the sliding block wheel, and the automatic speed regulating function is achieved. On the premise of carrying out automatic speed change through the centrifugal force, the centrifugal automatic speed change gear has the advantages of being smaller and more compact in structure, more excellent in speed change performance, safe, reliable, longer in service life and high in transmission efficiency, and is suitable for being popularized and developed in the industry.

Description

technical field [0001] The invention relates to the field of mechanical traditional gear shifting, in particular to a transmission device that utilizes centrifugal force to realize automatic gear shifting. Background technique [0002] The transmission device is widely used in vehicles, such as the transmission device used on the variable speed mountain bike, the rider changes the speed of the vehicle by changing the cooperation of the chain and different driving and driven gear plates. The size of the driving chainring and the size of the driven chainring determine the strength of the bicycle when turning the pedals. The larger the driving chainring is, the smaller the driven chainring is, and the harder it is to pedal. The smaller the driving chainring and the larger the driven chainring, the easier it is to pedal. According to the ability of different drivers, the speed of the bicycle can be adjusted by adjusting the size of the active and driven chainrings, or to cope ...
