Technical Field
The invention relates to a stepless speed change device of a manual bicycle, and belongs to the technical field of bicycles.
Background
At present, in the speed changer of bicycles on the market, the transmission ratio of front and rear chain wheels is changed by changing the size of the chain wheels for speed regulation, and gears are required to be shifted during the speed regulation so that chains are shifted to the corresponding chain wheels. The bicycle can only change speed when a chain wheel and a chain move during riding, the speed change device can be damaged by forced speed change when the bicycle is static, obvious pause and frustration are caused during speed change, and sometimes the chain wheel and a wheel disc cannot be well butted to cause chain dropping due to too fast and too slow gear shifting.
Disclosure of Invention
In view of the problems and deficiencies of the prior art, the invention provides a manual bicycle stepless speed change device. The invention realizes stepless speed change by changing the transmission ratio of the main wheel and the auxiliary wheel, provides the stepless speed change device of the bicycle with optional transmission ratio, and realizes comfortable riding experience without pause and contusion. The invention is realized by the following technical scheme.
A stepless speed change device of a manual bicycle comprises a front wheel disc 14 and a rear wheel disc 15 which are identical in structure, wherein the front wheel disc 14 is connected with the rear wheel disc 15 through a belt 12, the front wheel disc 14 and the rear wheel disc 15 respectively comprise a main wheel 1, an auxiliary wheel 2, a transmission wheel 3, an expansion link 4, a sliding plate 5, a shifting sheet 6, a spring 7, a blocking sheet 8, a steel wire rope 9, a main shaft 10, an auxiliary shaft 11 and an outer cylinder 13, the main shaft 10 of the front wheel disc 14 is connected with a pedal, the blocking sheet 8, the spring 7 and the shifting sheet 6 are sequentially arranged on the main shaft 10, small holes are formed in the blocking sheet 8 and the shifting sheet 6, the steel wire rope 9 penetrates through the small holes of the shifting sheet 6 to be hung in the small holes of the blocking sheet 8, the shifting sheet 6 is fixedly connected with the sliding plate 5, the sliding plate 5 is sleeved on the main shaft 10 in a clearance, a plurality of slideways extending to, the tail end of the telescopic rod 4 is fixed on an external outer cylinder 13; the central position of main shaft 10 is equipped with and drives pivoted main wheel 1 through main shaft 10, a drive wheel 3 is installed in the cooperation of different circumferences to main wheel 1, every drive wheel 3 cooperates a secondary wheel 2 again, secondary wheel 2 is the toper body of slope, drive wheel 3 also can be followed the slope slip of secondary wheel 2 slope toper body when following telescopic link 4 slip, every drive wheel 3 is fixed on urceolus 13 outside through auxiliary shaft 11, be equipped with a plurality of transmission wheel holes on the urceolus 13 cylinder, every transmission wheel hole all corresponds a drive wheel 3 and exposes the teeth of a cogwheel of drive wheel 3 one side, preceding rim plate 14 and back rim plate 15 are through carrying out the transmission between the teeth of a cogwheel that drive wheel 3 exposes and the slide caliper rule of belt 12 complex.
The stepless speed change device of the manual bicycle has the working principle that:
during the variable speed, through the wire rope 9 of manual pulling front wheel dish 14, plectrum 6 compression spring 7 to drive slide 5 and remove to separation blade 8 direction, slide 5 drives telescopic link 4 and removes to separation blade 8 direction, because telescopic link 4 fixes on the urceolus inner wall, telescopic link 4 can remove the extension along with slide 5, and moves down in slide 5 slide. The drive wheel 3 on the telescopic link 4 produces along with telescopic link extension 4 and moves to separation blade 8 direction, and drive wheel 3 moves on main wheel 1, and the people drives main wheel 1 rotatory when riding, and main wheel 1 drives drive wheel 3 rotatory, and drive wheel 3 drives the rotation of auxiliary wheel 2, and auxiliary wheel 2 drives belt 12, and this is that the drive ratio of main wheel 1 and auxiliary wheel 2 can change, can be laborsaving during the upslope. If the steel wire rope 9 is loosened, the spring 7 is stretched, so that the driving wheel 3 slides from the main wheel 1, and the riding is faster.
The effect of the steel wire rope 9 for pulling the rear wheel disc 15 is opposite to the effect of the front wheel disc 14, the transmission ratios of the main wheel 1 and the auxiliary wheel 2 of the two wheel discs are simultaneously adjusted, the total transmission ratio achieves the product effect, and the effect is more obvious.
The invention has the beneficial effects that:
the invention realizes stepless speed change by changing the transmission ratio of the main wheel and the auxiliary wheel, provides the stepless speed change device of the bicycle with optional transmission ratio, and realizes comfortable riding experience without pause and contusion.
