Abstract
The utility model relates to an accelerating effort-saving device for bicycle, comprises a chain wheel seat matched with the chain wheel of the bicycle. The chain wheel seat is connected with a clutch gear; the clutch gear is meshed with a sector gear wheel; a slide block is fixed to the sector gear wheel; the slide block is movably connected with a foot rest rod; the slide block is provided with a speed change mechanism. The utility model has good speed changing accuracy, agility, labour saving and durability.
Description
The utility model relates to a kind of bicycle speed change, work-saving device, can be widely used on bicycle, three-wheel vehicle and other rickshaw.
The enforcement of bicycle is finished for power by foot-operated, improves the speed of a motor vehicle, alleviates the long-term hope that legpower is people.Existing bicycle change-speed box is made up of the gear of one group of different number of teeth on same axle, drive driving lever by a backguy and stir chain, chain is shifted one's position, be meshed with the gear of the different numbers of teeth, thereby reach the purpose of speed change, because driving lever and chain matching coordinative are poor, thereby the speed change poor accuracy, damage easily.
The purpose of this utility model is to overcome the shortcoming of prior art, has proposed a kind of lever bicycle acceleration, work-saving device, has good, flexible, laborsaving, the durable characteristics of speed change accuracy.
The utility model comprises a chain pulley seat that can match with the sprocket wheel of bicycle, a said chain pulley seat and a clutch gear link, clutch gear is meshed with a fan type gear, fix a slide block on the fan type gear, slide block becomes active connection with a foot-driven lever, and the strong point of foot-driven lever can be fixed on the hind axle of bicycle.Fix a variable gear on the said chain pulley seat, variable gear is meshed with a passive variable gear, disposes the speed change tooth that can be meshed with clutch gear on the passive variable gear.
During use, with foot-operated moving foot-driven lever, then foot-driven lever drives fan type gear movement by slide block, and fan type gear is given clutch gear, chain pulley seat and sprocket wheel with transmission of power, travels forward thereby sprocket wheel drives the bicycle trailing wheel.
When needing speed change, support hand on the pulling clutch gear, then clutch gear is separated with chain pulley seat and is meshed with speed change tooth on the passive variable gear simultaneously, passive variable gear is given chain pulley seat and sprocket wheel by the variable gear on the chain pulley seat with transmission of power, travels forward thereby sprocket wheel drives the bicycle trailing wheel.
This shows, the utlity model has following characteristics:
(1) adopts the lever foot-driven lever, have and save time the labour-saving effect;
(2) adopt the clutch gear speed-changing mechanism, thereby have good, flexible, the durable characteristics of speed change accuracy.
Fig. 1 is an assembling schematic diagram of the present utility model.
Fig. 2 is a rigging position scheme drawing of the present utility model.
Fig. 3 is a structure principle chart of the present utility model.
Fig. 4 is the A view.
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are done detailed explanation.
With reference to Fig. 1, in the and arranged on left and right sides of bicycle transmission device one device of the present utility model is housed respectively, be used alternatingly to be suitable for left and right pin.
With reference to Fig. 2-4, the utility model comprises a foot-driven lever (1), the strong point (12) of foot-driven lever (1) is fixed on the bicycle rear shaft, the centre portion of foot-driven lever (1) disposes a slide block (11), slide block (11) can slidably reciprocate in the slotted hole (21) on foot-driven lever, slide block (11) is by nut (22), backing pin (20), axle (10) is fixed on the take-up housing (19), take-up housing (19) is fixed on the fan type gear (2) by screw thread (18), tooth on a tooth on the fan type gear (2) and the clutch gear (6) is meshed, clutch gear (6) matches with a chain pulley seat by a joint ladder axle (13), chain pulley seat (15) is fixed on the sprocket wheel (3) by bolt (16), chain pulley seat (15) is gone up assembling one variable gear (7), variable gear (7) is meshed with a ring gear (8), disposes the speed change tooth (24) that can be meshed with clutch gear (6) on the ring gear (8).In addition, among the figure, (5) are clutch gear support hands, and (14) are that key, (17) are that bearing, (23) are that clutch gear deciliter face, (4) are that bicycle rear, (9) are chains.
During use, with foot-operated moving foot-driven lever (1), then foot-driven lever (1) drives fan type gear (2) motion by slide block (11), fan type gear (2) is given clutch gear (6), chain pulley seat (15) and sprocket wheel (3) with transmission of power, travels forward thereby sprocket wheel (3) drives bicycle trailing wheel (4) by chain (9).
When needing speed change, pulling support hand (5), then deciliter face (23) be separated with chain pulley seat (15) and simultaneously clutch gear (6) be meshed with speed change tooth (24) on the passive variable gear (8), passive variable gear (8) is given chain pulley seat (15) and sprocket wheel (3) by the variable gear (7) on the chain pulley seat (15) with transmission of power, travels forward thereby sprocket wheel (3) drives bicycle trailing wheel (4) by chain (9).
The power arm of foot-driven lever among the utility model embodiment (1) is 2 times of its resistance arm, like this, can obtain 3 times of effects to foot-operated power, once back and forth equals 2 weeks of existing circumference rocking arm, and the work tooth of fan type gear is 20, and the tooth of connection floral disc is 10.
Claims (2)
1, bicycle acceleration, work-saving device, comprise a chain pulley seat that can match with the sprocket wheel of bicycle, feature of the present utility model is, a said chain pulley seat and a clutch gear link, clutch gear is meshed with a fan type gear, fix a slide block on the fan type gear, slide block becomes active connection with a foot-driven lever.
2, foot-operated acceleration according to claim 1, work-saving device, it is characterized in that, fix a variable gear on the said chain pulley seat, variable gear is meshed with a passive variable gear, disposes the speed change tooth that can be meshed with clutch gear on the passive variable gear.
