Abstract
The utility model belongs to the technical field of bicycle, in particular to a bicycle driving gear with rack and foot lever. A driving gear of the utility model is composed of two sets of symmetrical pedal lever type driving devices with rack, which are arranged respectively on the both sides of the rear wheel shaft, the rack is driven by the pedal lever to dirve the rear wheel to rotate, and the speed-variable is conveniently achieved by adjusting the fixation position of the rack and the pedal lever. The utility model changes the common wheel chain link driving device, so the original circumference motion of the foot is changed into the simple up and down motion of stepping, meanwhile, the utility model has the advantages of short bicycle body, reduction weight and labour saving when people ride.
Description
The utility model belongs to technical field of bicycles, particularly a kind of driver train of bicycle.
" science magazine " the 6th phase in 1980 had once been reported a kind of pedal-type bicycle, and this bicycle has changed chain wheel commonly used, and chain drive directly drives flywheel with the sector rack on the pedal and rotates.In the time of by bike, make the circular movement of original sole become to step on simply up and down and pedal motion, vehicle body is shortened, but this pedal-type bicycle is equipped with gear No. three in a side of rear axle, on two pedals three toothed rack are arranged, be meshed with No. three gears respectively, its structure more complicated also is not easy speed change.Task of the present utility model is to provide a kind of new foot pedal lever formula rack drives mechanism for overcoming above-mentioned shortcoming.
The utility model is made up of symmetrical two groups of foot pedal lever formula rack drives devices, is installed in the both sides of trailing wheel respectively, every group of gear by a band overriding clutch, and tooth bar, the tooth bar hold down groove is formed with the foot pedal lever that is connected tooth bar.
Fig. 1. be the view of the utility model pedal type rack drives mechanism.
5. gear with freewheel clutch among the figure is installed on the hind axle, gear be set with on 5. the tooth bar holddown groove 4., 5. 3. tooth bar mesh with gear in this groove, and can slide up and down along this groove, 5. driven gear rotates. The rear axle of vehicle frame is provided with foot pedal lever fulcrum frame 1. and 9. goes up and can be equipped with an elasticity lock-bit bar 6., gives foot pedal lever stroke location 1.. When 1. foot pedal lever is positioned to bottom dead centre, also can be used as the support of bicycle, foot pedal lever rear end (being the resistance arm end) 1. has an elongated slot 3. to be connected with tooth bar, and 3. 2. foot pedal lever also can be connected with tooth bar by a movable connecting plate. The portable plate 2. position in elongated slot is adjustable, 2. change tooth bar 3. at the stroke of tooth bar holddown groove in 4. in the position in elongated slot by changing movable connecting plate, to adapt to the speed change request on different road surfaces, foot pedal lever front end (being the power arm end) 1. is provided with foot-operated. 9. be provided with an interlock steel wire rope 7. at pedal and fulcrum frame between, 7. this steel wire rope can hang over a fixed pulley and 8. go up, and makes left and right sides foot pedal lever linkage from top to bottom.
When riding, depressing left-hand tread plate 1. lifts its rear end, in the process of lifting, 2. drive tooth bar 3. along 4. upward movement of tooth bar hold down groove by portable plate, 5. the gear that is engaged with is rotated, drive wheels is rotated forward, under the effect 7. of interlock steel rope, right-hand tread plate lever front end 1. rises, and steps the right-hand tread plate lever more 1. simultaneously, the left and right sides alternately steps like this, can drive bicycle running.
The utility model is simple in structure, and frame is shortened, weight saving, and it is laborsaving to ride.
