Abstract
The utility model belongs to perambulator appliance technology more particularly to a kind of flexible perambulator of driving.The utility model discloses driving soul boy's vehicles, including front vehicle wheel, rear wheel and vehicle frame, driving gear and driven gear are provided on vehicle frame, the driving gear and driven gear includes gear ring and the bar shaped rack gear that is arranged on gear ring, the bar shaped rack gear is plastic-steel item, it is connected between the driving gear and driven gear by wear-resisting plastic-steel belt, the bar shaped grinding tooth being meshed with bar shaped rack gear is provided on wear-resisting plastic-steel belt.Bar shaped rack gear, gear ring make stable drive, without noise.And it is also cleaner than chain drive after bar shaped rack gear, gear ring use, it will not get rusty conducive to maintenance.The beneficial effects of the utility model are: stable drive, also cleaner than chain drive after use without noise, will not get rusty conducive to maintenance.
Description
Technical field
The utility model belongs to perambulator appliance technology more particularly to a kind of flexible perambulator of driving.
Background technique
The driving device of perambulator used at present is typically all to use gear and chain, and gear and chain are all to use iron
Matter or steel, and the tooth head of gear is all sharp, and on chain it is also the gap that setting is matched with the tooth head of sharp.
It is to children since perambulator is more special, so being with the difference of adult bicycle: children's strength is small, and weight is smaller,
So the power that perambulator needs to drive is smaller, so biggish hum is had when transmission using common gear and chain,
And gear and chain, so being easy to get rusty, are needed to be maintained using irony, and maintenance is more troublesome, and gear
It is inadequate with chain cleaning degree.
Summary of the invention
Utility model aims to solve techniques discussed above problems, provide a kind of stable drive, without noise,
Also cleaner than chain drive after use, conducive to the flexible perambulator of driving that maintenance will not get rusty, its technical solution is as follows:
Drive flexible perambulator, including front vehicle wheel, rear wheel and vehicle frame, which is characterized in that driving gear is provided on vehicle frame
And driven gear, the driving gear and driven gear include gear ring and the bar shaped rack gear that is arranged on gear ring, described
Bar shaped rack gear be plastic-steel item, between the driving gear and driven gear by wear-resisting plastic-steel belt be connected, wear-resisting plastic-steel belt
On be provided with the bar shaped grinding tooth being meshed with bar shaped rack gear.Bar shaped rack gear, gear ring make stable drive, without noise.And
It is also cleaner than chain drive after bar shaped rack gear, gear ring use, it will not get rusty conducive to maintenance.
Further, the driving gear includes arc reinforcing rib and pedal connector, and pedal connector is to gear ring
4 bulge-structures are extended with, the both ends of the arc reinforcing rib are connected with 2 adjacent bulge-structures respectively, described
The interlude of arc reinforcing rib is connected with the inside of gear ring；Two are constituted between bulge-structure, arc reinforcing rib and gear ring
Triangle short slot.It is circular that the effect of arc reinforcing rib, which is due to gear ring, so the arc shape by arc reinforcing rib can
So that the contact surface with gear ring is bigger, so that booster action maximizes.Bulge-structure, arc reinforcing rib and tooth
Two triangle short slots are constituted between wheel rim, triangle short slot triangular shape has better stability, so as to rise
It is acted on to better supporting & stablizing.
The beneficial effects of the utility model are: stable drive, also cleaner than chain drive after use without noise, benefit
It will not get rusty in maintenance.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of driving gear.
Specific embodiment
Below with reference to Fig. 1 and Fig. 2 specific illustrative embodiment:
Flexible perambulator, including front vehicle wheel 1, rear wheel 2 and vehicle frame 3 are driven, driving gear 4 and passive is provided on vehicle frame
Gear 5, the driving gear and driven gear include gear ring 6 and the bar shaped rack gear 7 that is arranged on gear ring, the item
Shape rack gear is plastic-steel item, is connected between the driving gear and driven gear by wear-resisting plastic-steel belt 8, is set on wear-resisting plastic-steel belt
It is equipped with the bar shaped grinding tooth 9 being meshed with bar shaped rack gear.Bar shaped rack gear, gear ring make stable drive, without noise.And bar shaped
It is also cleaner than chain drive after rack gear, gear ring use, it will not get rusty conducive to maintenance.
Further, the driving gear includes arc reinforcing rib 10 and pedal connector 11, pedal connector 11 to
Gear ring is extended with 4 bulge-structures 12, and the both ends of the arc reinforcing rib are connected with 2 adjacent bulge-structures respectively
It connects, the interlude of arc reinforcing rib is connected with the inside of gear ring；Between bulge-structure, arc reinforcing rib and gear ring
Constitute two triangle short slots 13.It is circular that the effect of arc reinforcing rib, which is due to gear ring, so passing through arc reinforcing rib
Arc shape can make it is bigger with the contact surface of gear ring so that booster action maximize.Bulge-structure, arc
Two triangle short slots are constituted between reinforcing rib and gear ring, triangle short slot triangular shape has better stability,
So as to play the role of better supporting & stablizing.
