By keeping away vibrating 1 and rear wheel frame 2, rear wheel 6, forming bicycle rear and keep away the mechanism of shaking. This mechanism is with existing to keep away the bicycle that shakes identical, by chain sprocket 3, chain 4, swollen sprocket wheel 5 and initiatively flywheel 7, formed the bicycle main transmission mechanism. This part can adopt existing single speed or multi-speed exchanged transmission mechanism. The boosting mechanism of bicycle is by Amplitude amplification tooth pulley 8, vehicle frame boosting-rod 9, add riding chain extension spring 10, extension spring hanging seat 11, add riding chain hanging seat 12, afterburning flywheel 13 and add riding chain 14 and consist of, the bicycle boosting mechanism can the parallel the same face that is installed in wheel with main drive gear, also can be installed in the another side of wheel, 13 is afterburning flywheels among Fig. 2, adopt Regular Bicycle flywheel or the special more reverse-threaded flywheel of internal tooth, be installed in the left side of bicycle rear. The 14th, add riding chain, its end is fixed on and adds on the riding chain hanging seat 12, add riding chain upwards by Amplitude amplification tooth pulley 8 and afterburning flywheel 13 engagements, the other end connects and adds riding chain extension spring 10, adding the riding chain extension spring hangs on the extension spring hanging seat 11, by adjusting different hanging holes, can adjust easily the tightness that adds riding chain. During bicycle running, the pitch force of generation drives Amplitude amplification tooth pulley 8 by main car frame through boosting-rod 9, moves up and down. Suppose Amplitude amplification tooth pulley 8, when moving upward, i.e. pulling adds riding chain 14, drive afterburning flywheel 13, rotate clockwise certain angle, form the forward travel of wheel 6, because Amplitude amplification tooth pulley 8 is equivalent to a movable pulley, its motion amplitude can form the moving width of cloth that adds the riding chain twice, therefore played the effect of amplifying the moving width of cloth, after This move was finished, the tooth pulley was because the rebound effect that bicycle is kept away vibrating when moving, adds riding chain 14 downwards, in afterburning extension spring 10, effect under pull back and drive afterburning flywheel 13 and make counterclockwise Free, get back to original position, rotate because afterburning flywheel is the one direction reinforcing. Counter-clockwise direction is not work done of Free. Jolt owing to constantly produce in the bicycle running process, so afterburning flywheel just constantly produces clockwise reinforcing, bicycle pitches and the merit that consumes has changed into motoricity forwards thus.

Another kind of design is to adopt a kind of special afterburning flywheel, cooperate with bicycle active flywheel, initiatively flywheel just meshes with afterburning flywheel automatically when cyclist's step tread, when stopping firmly, afterburning flywheel will be automatically and the wheel disengaging, the shortcoming that afterburning type bicycle rear can not reverse can be changed like this, reinforcing can be when the downhill path, automatically stopped again.

In order to make afterburning type bicycle evenly afterburning, also can adopt with the afterburning flywheel of the accumulating type of accumulation of energy clockwork spring wind spring, like this, afterburning flywheel just stores the power that can not at once transform on the clockwork spring wind spring when shaking when bicycle is run rapidly, at any time automatically discharges to wheel. In order more effectively to utilize all utilizable power, this augmentor not only can be applied on the rear wheel, and can make same boosting mechanism at front-wheel, make availability of force higher.

Fig. 3 adopts small size steel wire rope to make the schematic diagram that adds riding chain, and 2 is rear wheel frames, the 8th among the figure, Amplitude amplification pulley, the 9th, boosting-rod, the 10th, afterburning extension spring, the 11st, extension spring hanging seat, the 12nd, afterburning steel wire rope hanging seat, the 13rd, afterburning flywheel, the 14th, afterburning steel wire rope. The action principle of each part is identical with Fig. 2, no longer state more.

Fig. 4 adopts the boosting mechanism scheme drawing of lever tooth bar as afterburning element, 2 is rear wheel frames, the 6th among the figure, rear wheel, the 13rd, afterburning flywheel, the 14th, afterburning tooth bar, the 9th, boosting-rod, the motion that pitches that bicycle produces under steam is connected to boosting-rod 9, drives afterburning tooth bar 14 and move up and down by main car frame.Afterburning flywheel 13, by the gear teeth and afterburning 14 engagements, do positive and negative rotation, because flywheel is unidirectional reinforcing, so when just changeing, wheel rotates, and is idle running during counter-rotating thereupon thereupon.

With the afterburning type bicycle that the utility model is made, travel steadily, at a high speed, can increase substantially the degree of utilization of power, it is more easily laborsaving to ride.
