Abstract
A double-speed bidirectional bicycle comprises a frame, a front wheel, a rear wheel, a tooth disc and a flywheel, which are arranged on the frame, and a chain for connecting the tooth disc and the flywheel, and is technically characterized in that the flywheel is a double-speed bidirectional connected flywheel consisting of a high-speed flywheel and a low-speed flywheel, a chain support wheel is further arranged on the frame, and a chain on the tooth disc is connected with the high-speed flywheel through the low-speed flywheel and the chain support wheel. When riders run the bicycle forwards, the chain on the upper portion of the tooth disc can drive the low-speed flywheel forwards, the chain under the tooth disc can drive the high-speed flywheel to idle backwards, thus the bicycle has the power to move forwards, when the riders run the bicycle backwards, the chain under the tooth disc can drive the high-speed flywheel to move forwards, and the chain on the upper portion of the tooth disc can drive the low-speed flywheel to idle backwards. The double-speed bidirectional bicycle can move forwards no matter riders run the bicycle forwards or backwards, which can excite muscle of the ridders which is not often exercised, can promote blood circulation and balance human functions, is good for health, and can improve the forward moving speed of the bicycle when running backwards.
Description
Technical field:
The utility model relates to a kind of bicycle, two-way the stepping on by bike of specifically a kind of double speed.
Background technology:
Seen in the market bicycle is that ordinary bicycle or variable speed bicycle all are to have only to pedal forward to produce the power that moves ahead.When urgency long when ride period, that pedal was a bit, rider's shank just had the sensation of aching, at this moment, we can be habitually backward reversing sense pedal for a moment, alleviate the pressure of shank.But when reversing sense is pedaled backward, do not produce power, influence preceding line speed by bike.Particularly pedaling forward for a long time to stimulate seldom movable muscle, is unfavorable for the balance function of human body.
Summary of the invention:
Deficiency in view of above-mentioned prior art existence; the purpose of this utility model provide a kind of no matter be pedal forward, still kicking backward to produce two-way the stepping on by bike of double speed that allows action edge before the bicycle; make it not influence moving ahead by bike; can stimulate seldom movable muscle; stimulate circulation, the balance function of human body, good for health.
The purpose of this utility model is achieved in that its chain wheel on comprising vehicle frame, front and rear wheel and being located at vehicle frame is with flywheel and be connected chain wheel and the chain of flywheel, it is characterized in that: flywheel is a two-way conjoined flywheel of double speed that is made of high speed flywheel and low-speed flywheel, one chain support wheel also is set on vehicle frame, and chain is connected with high speed flywheel through low-speed flywheel, chain support wheel on the chain wheel.When the cyclist was pedaled forward, the chain of chain wheel top drove low-speed flywheel (being relatively large flywheel) forward, and the chain of chain wheel below then drives high speed flywheel (promptly relatively than small flywheel) and dallies backward, and bicycle just has the power that moves ahead like this; When the cyclist kicked backward, the chain of chain wheel below then drove high speed flywheel and turns round forward, and at this moment the chain of chain wheel top then drives low-speed flywheel and dallies backward.So no matter be pedal forward, still kicking backward to produce the power that allows bicycle move ahead.
The utility model has the advantages that it is to pedal forward, still kick backward not influence moving ahead by bike, can stimulate seldom movable muscle, stimulate circulation, the balance function of human body, good for health, also can improve preceding line speed by bike when kicking backward.
Below in conjunction with accompanying drawing the utility model is done with explanation.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
By accompanying drawing as can be known, the utility model comprises vehicle frame 5, front and back wheel 8,9, chain wheel 7, chain support wheel 4, chain 6 and the two-way conjoined flywheel 1 of double speed that is made of high speed flywheel 3 and low-speed flywheel 2.Front and back wheel 8,9 vehicle frame 5 front and rear parts that are placed in, the two-way conjoined flywheel 1 of double speed and trailing wheel 9 coexist on the rear axle at vehicle frame 5 rear portions; Chain wheel 7 places on the vehicle frame 5 middle part axis, drives chain wheel 7 rotations by the pedal 10 that is fixed on the axis; Chain support wheel 4 places between vehicle frame 5 upper chain wheels 7 and the two-way conjoined flywheel 1 of double speed; Chain 6 begins above chain wheel 7 above the low-speed flywheel 2 of the two-way conjoined flywheel of double speed, raps around to above the high speed flywheel 3 of the two-way conjoined flywheel of double speed by chain support wheel 4, again below chain wheel 7 around above chain wheel 7, connecting.When the cyclist was pedaled forward, the chain 6 of chain wheel 7 tops drove low-speed flywheel 2 (being relatively large flywheel) forward, and the chain 6 of chain wheel 7 belows then drives high speed flywheel 3 (promptly relatively than small flywheel) and dallies backward, and bicycle just has the power that moves ahead like this; When the cyclist kicked backward, 6 on the chain of chain wheel 7 belows drove high speed flywheel 3 and turn round forward, and at this moment the chain above the chain wheel then drives low-speed flywheel 2 and dallies backward.So no matter be pedal forward, still kicking backward to produce the power that allows bicycle move ahead, the speed that the flywheels decision bicycles that vary in size by two move ahead promptly realizes double speed, by bike preceding line speed is very fast when kicking backward.
