Background technology
Bicycle is the band step vehicle of China wage-earners, and development in recent years is the instrument that daily exercise and tourism are ridden.Traditional bicycle is manually driven pedal type bicycle, fuel bicycle, Electrical Bicycle or the like.It is, fuel oil or electric boosted foot-operated by manpower that the bicycle of these types drives power.All do not having to install on known all kinds of bicycle or the boosted vehicle in the market by mechanically aided driving device.
Summary of the invention
The purpose of this utility model is to be bicycle, fuel bicycle or Electrical Bicycle, the mechanically aided device of the bicycle of providing a kind of and be fit to long-distancely to ride, tractive performance is good, guarantees safety performance.
The mechanically aided device content Description of the utility model bicycle:
The mechanically aided device of the utility model bicycle, it is characterized in that: bumper 14 is fixed on the flywheel of bicycle rear, the tooth bar 1 that length of spring compressed in the bumper 14 is connected with the other end of bumper 14, be arranged on the both sides and the flywheel 2 of the tooth bar 1 in the mechanically aided device shell of bicycle, tooth on the flywheel 3 is meshed, sprocket wheel 4 and flywheel 2 consubstantialities, sprocket wheel 5, sprocket wheel 6 and flywheel 3 consubstantialities, sprocket wheel 4 and sprocket wheel 5 are connected by chain, sprocket wheel 6 and sprocket wheel 7 are connected by chain, sprocket wheel 8 and sprocket wheel 9 are connected by chain, sprocket wheel 10 and sprocket wheel 11 are connected by chain, sprocket wheel 12 and sprocket wheel 13 are connected by chain; Sprocket wheel 10 is a disc shaped box body shape, and its excircle place is a tooth, and the disc spring is set in box body, and an end of disc spring links to each other with anchor shaft, and the other end links to each other with sprocket wheel 10 disc shaped box bodys, and brake 15 is set on the excircle of sprocket wheel 10 box bodys; Sprocket wheel 11 and sprocket wheel 12 consubstantialities, sprocket wheel 10 is given sprocket wheel 11 with transmission of power, passes to sprocket wheel 13 by sprocket wheel 12 again, and sprocket wheel 13 is installed in the opposite side of bicycle freewheel.
The mechanically aided device of the utility model bicycle, can be installed on bicycle, fuel bicycle or the Electrical Bicycle, have that volume is little, in light weight, safe and reliable, the characteristics of long service life, make laborsaving, the light and fast of cycling, be convenient to long-distance riding.
Description of drawings
Fig. 1 is the mechanically aided device structural representation of bicycle
Fig. 2 is the bicycle structure figure that has the mechanically aided device of bicycle
Among the figure: 1 is that tooth bar, 2 is that flywheel, 3 is that flywheel, 4 is that sprocket wheel, 5 is that sprocket wheel, 6 is that sprocket wheel, 7 is that sprocket wheel, 8 is that sprocket wheel, 9 is that sprocket wheel, 10 is that sprocket wheel, 11 is that sprocket wheel, 12 sprocket wheels, 13 are that sprocket wheel, 14 is that bumper, 15 is a brake
The specific embodiment
The mechanically aided device of the utility model bicycle is achieved in that to be seen and Fig. 1 specifies below in conjunction with accompanying drawing.The mechanically aided device of the utility model bicycle, it is characterized in that: bumper 14 is fixed on the bicycle rear, the tooth bar 1 that length of spring compressed in cycle racing in the bumper 14 is connected with the other end of bumper 14, be arranged on the both sides and the flywheel 2 of the tooth bar 1 in the mechanically aided device shell of bicycle, tooth on the flywheel 3 is meshed, tooth bar 1 is done straight-line motion up and down, then flywheel 2, flywheel 3 rotates, when tooth bar 1 makes progress, flywheel 3 clockwise direction load movements, at this moment flywheel 2 reversing sense zero loads, tooth bar 1 is downwards the time, flywheel 2 clockwise direction load movements, flywheel 3 reversing sense zero loads.Because sprocket wheel 4 and flywheel 2 consubstantialities, sprocket wheel 5, sprocket wheel 6 and flywheel 3 consubstantialities, sprocket wheel 4 and sprocket wheel 5 are connected by chain, so each linear reciprocating motion of tooth bar 1 can both be made sprocket wheel 6 the clockwise direction rotation.Sprocket wheel 6 and sprocket wheel 7 by chain be connected, sprocket wheel 8 and sprocket wheel 9 by chain be connected, sprocket wheel 10 and sprocket wheel 11 by chain be connected, sprocket wheel 12 and sprocket wheel 13 be connected by chain, sprocket wheel 13 is installed in the opposite side of bicycle freewheel; Sprocket wheel 10 is a disc shaped box body shape, its excircle place is a tooth, the disc spring is set in box body, the power that transmits by sprocket wheel 8 when sprocket wheel 9 makes the rotation of sprocket wheel anchor shaft, drive the disc spring rotation in the sprocket wheel 10, and make disc spring storing power when rotated, one end of disc spring links to each other with anchor shaft, the other end links to each other with sprocket wheel 10 disc shaped box bodys, brake 15 is set on the excircle of sprocket wheel 10 box bodys, when not needing power-assisted, brake 15 is closed, when riding brake 15 is opened, discharge power, make sprocket wheel 10 rotations.Sprocket wheel 11 and sprocket wheel 12 consubstantialities, sprocket wheel 10 is given sprocket wheel 11 with transmission of power, passes to sprocket wheel 13 by sprocket wheel 12 again, reaches to drive the purpose that bicycle quick is advanced.
The acquisition of the mechanically aided device power of the utility model bicycle and output drive with former car does not have any relation, and when force aid system quits work, former car can be ridden walking as usual, and is unaffected.
