Abstract
The present invention relates to " bicycle with toothed wheel of changeable transmission ratio " after a kind of improve, when the needs bicycle is run at high speed, the variable gear clutch on the control linkage clutch and the left side, then by be welded on bicycle tripod on shape triangular supports the change wheel of captive joint be meshed, through after the speed change of step-by-step variable gear, pass to sprocket wheel at last, improve the bicycle speed of a motor vehicle.When the needs bicycle low-speed travelled, the variable gear clutch on control linkage clutch and the right directly passed to sprocket wheel to people's pedal power, kept the bicycle speed of a motor vehicle generally.
Description
The present invention relates to a kind of improved variable speed bicycle, particularly, improve the speed of a motor vehicle (comprising bicycle) of bicycle by behind the multi-stage gear speed-changing.
Existing variable speed bicycle mainly is by the various combination of many groups sprocket wheel with many groups flywheel size ratio, reaches the speed change of the bicycle speed of a motor vehicle, and the variable speed bicycle of selling on the market is exactly this form.But because bicycle is subjected to the restriction of this body structure, sprocket wheel all is limited with the raising of flywheel multi-speed ratio, thereby the raising of the speed of a motor vehicle of variable speed bicycle also is limited.
Task of the present invention is that a kind of improved bicycle that improves the bicycle speed of a motor vehicle by multi-stage gear speed-changing will be provided.It can select running at high speed or travelling at a slow speed of bicycle by the control of power-transfer clutch very easily.
Task of the present invention is finished like this, when the needs bicycle is run at high speed, the variable gear clutch on the control clutch and the left side, then by be welded on bicycle tripod on a shape triangular supports on the variable gear of captive joint be meshed, speed change through step-by-step variable gear, at last, improve the bicycle speed of a motor vehicle.When needs travelled at a slow speed, the variable gear clutch on control clutch and the right was directly passed to sprocket wheel to the human body pedal power, kept the bicycle speed of a motor vehicle generally.
Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is a front view of the present invention.
Fig. 2 is the attached view of A-A of the present invention.
Fig. 3 is that A of the present invention is to the rotation left view.
With reference to accompanying drawing, dead ahead at original bicycle middle shaft bearing seat 15, there have a leg-of-mutton support 26 of shape and cycle frame 3 and bottom bracket bearing seat 15 to weld mutually to be fixing, weld again in the both sides of support 26 fixed 2 bearing seat 27(also during fabrication bearing seat 27 be fabricated to one with support 26), it is fixing with captive nut 29 that front axle 24 passes both sides, bearing seat 27 supports, 26 back, its fixed form and original bottom bracket bearing seat 15 fixedly axis 18 form identical, at two of front axle 24 flat key 23, fix either ratio gear 30 and variable gear 25 are used back-up ring 22 then, screw 21 is fixing.Original axis 18 is prolonged to two edge axis directions, respectively establish a power-transfer clutch 34 on the both sides of axis 18, in power-transfer clutch, respectively there is a slide key 33 to be screwed on axis 18, power-transfer clutch can be endwisely slipped in flat key 33 upper edges, and have variable gear 31 clutch mutually of side tooth with side, the left side, variable gear 31 is meshed with variable gear 30 again, and variable gear 31 uses antifriction-bearing box 17, and the axis hole outer ring is fixing with back-up ring 35, screw 32.Inner ring is fixing with garden nut 19, the right power-transfer clutch 34 of axis 18 and variable gear 16 clutch mutually that has the side tooth, variable gear 16 is meshed with variable gear 25 again, variable gear 16 usefulness antifriction-bearing boxs 17, back-up ring is made with sprocket wheel 20 in the axis hole outer ring, be fixed on the variable gear 16 with nut 14, axis hole is fixing with garden nut 19.On two clutch 34 devices, there is a connecting rod 9 that two power-transfer clutchs 34 are associated in together, forms a linkage clutch.There is a driving lever 2 top of connecting rod, near the connecting rod place fulcrum 8 is arranged at driving lever 2, be fixed on bolt 7 on the cant beam of bicycle tripod 3, the troffer 5 that has the cold bundle of a usefulness iron plate to make on the top of driving lever, also be fixed on bolt on the cant beam of cycle frame 3, the driving lever termination while fixing of a spring 4 and support 5 arranged, the aperture that the another side of driving lever has steel cable 1 to pass on the support links to each other with driving lever 2, steel rope 1 link to each other with a controller that is installed in the bicycle handle bar again (not drawing among the figure), when needs select bicycle to run at high speed, press the controller on the handlebar, steel rope 1 pulling driving lever 2, leverage by fulcrum 8, linkage clutch 34 and variable gear 31 clutch mutually, human body steps the power of pedal by axis 18, flat key 33, linkage clutch 34 passes to variable gear 31, variable gear 31 is meshed with variable gear 30 and gives variable gear 25 through axis 24 transfer torques again after the speed change, variable gear 25 passes to the sprocket wheel 20 that is fixed by bolts on the variable gear 16 after meshing speed changes with variable gear 16, reaches the raising of the bicycle speed of a motor vehicle.When needs select bicycle low-speed to travel, press the controller (not drawing among the figure) on the handlebar, steel wire 1 ineffective power, because the application force of spring 4, linkage clutch 34 and variable gear 16 engagements, the power that manpower steps pedal passes to variable gear 16 by axis 18, flat key 33, linkage clutch 34, acts directly on the sprocket wheel 20, keeps the bicycle speed of a motor vehicle generally.
