Excess energy of the bicycle is stored; then the excess energy is converted to the dynamic energy of the bicycle. The utility model has no fuel consumption, no electrical energy consumption, no pollution, simple structure and low cost.

Description

Accelarators for bicycles

The utility model relates to a kind of work-saving device of bicycle

Known Accelarators for bicycles is spark ignition engine, diesel engine and electrical motor, and this class servo-unit needs consumes energy, and major part all produces a large amount of expense gas contaminated environment when work, can not make full use of energy, and usable horsepower is low, and purchases and build up Ben Gaoang.

The purpose of this utility model provides a kind of Accelarators for bicycles, and it does not consume dyestuff and electric energy, and is pollution-free, and cost is low.

The purpose of this utility model is achieved in that this servo-unit is mainly by fixed support, travel(l)ing rest, main gear, between gear, the energy gear, laminated spring, ratchet, ratchet, compositions such as effector, fixed support one end is fixed on the thick stick of the interior rear flank of bicycle, the fixed support other end connects the travel(l)ing rest middle part, main gear is fixed on the bicycle rear axle shell medial extremity, between gear and ratchet be connected the top of travel(l)ing rest through last axle, energy gear and ratchet are connected the bottom of travel(l)ing rest through lower shaft, between gear and energy gear intermesh, the laminated spring outer end is connected and fixed support, the inner lower shaft that connects of laminated spring, two control wires of effector connect the two ends of travel(l)ing rest respectively.

Described travel(l)ing rest is inside and outside two-layer, and internal layer and fixed support flexibly connect, laminated spring can inside and outside freely discharge between two-layer with energetically.

Described energy gear is the flywheel-type gear.

Described ratchet rear portion is connected with governing screw.

Described lower shaft and travel(l)ing rest be connected to flexible connection.

When the utility model can be with the bicycle descending or the excess energy that produces when very fast of the speed of a motor vehicle store, when the needs power-assisted, discharge again, be converted into the kinetic energy of bicycle, reach power-assisted purpose.It is consume fuel and electric energy not, and is pollution-free, has improved the usable horsepower of bicycle greatly, and simple in structure, easy to operate, cost is low, is beneficial to large-scale industrial production.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a constructional drawing of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is an erection plan of the present utility model.

The solidus screw is gone up in gear, (5) bicycle rear axle, (6) last axle, (7) governing screw, (8) fixed support, (9) travel(l)ing rest, (10) lower shaft, (11) ratchet, (12) ratchet, (13) energy gear, (14) laminated spring, (15) between (1) effector, (2) control wire, (3) main gear, (4) among the figure, (16) encircle spring, (17) forcing screw, (18) solidus screw down.

In Fig. 1 and Fig. 2, fixed support (8) is fixed on by bicycle rear axle (5) nut compressing in the bicycle on the thick stick of rear flank, travel(l)ing rest (9) is connected on the fixed support (8) by forcing screw (17), and travel(l)ing rest (9) can rotate to CC ' position from BB ' position.Main gear (3) is fixed on the bicycle rear axle shell medial extremity, rotates with bicycle rear.Between gear (4) can be around last axle (6) rotation, the interior wheel of energy gear (13) is captiveed joint with lower shaft (10).Do not drive interior wheel when the foreign steamer of energy gear (13) is clickwise, wheel in driving when foreign steamer is left-hand revolution rotates in the axis hole of travel(l)ing rest (9) thereby drive lower shaft (10).When lower shaft (10) when being left-hand revolution, laminated spring (14) is able to energetically.Lifting and falling of ratchet (11) is to be produced by the motion of travel(l)ing rest (9), the opportunity that governing screw (7) is used to regulate ratchet (11) engagement or decontrols ratchet (12).The rotation of travel(l)ing rest (9) is controlled by effector (1) by control wire (2).

In Fig. 3, effector (1) is contained on the bicycle handle bar.

Motion analysis of the present utility model: when the bicycle cruising, the joystick of effector (1) is in EE ' position, travel(l)ing rest (9) is in OO ' position, main gear (3) is left-hand revolution, between gear (4) all do not contact with energy gear (13) with main gear (3), servo-unit is idle state.

When the superfluous relatively needs of bicycle energy store, the joystick of effector (1) is removed to DD ' position.At this moment, travel(l)ing rest (9) is in BB ' position, a gear (4) and main gear (3) engagement.Between gear (4) driven by main gear (3) and be clickwise, make the foreign steamer of energy gear (13) be left-hand revolution, wheel and lower shaft (10) and ratchet (12) left-hand revolution in driving, laminated spring (14) is able to energetically.

When needs release energy when making bicycle be able to power-assisted, joystick is removed to FF ' position.At this moment, travel(l)ing rest (9) is shifted to CC ' position through the control wire traction, and a gear (4) is thrown off with main gear (3), energy gear (13) and main gear (3) engagement.Simultaneously, governing screw (7) is subjected to the uplift force of fixed support (8), make ratchet (11) decontrol ratchet (12), the torsional moment of laminated spring (14) makes lower shaft (10) be clickwise, the interior wheel of energy gear (13) drives its outer crop rotation clickwise, rotate counterclockwise thereby drive main gear (3), bicycle rear is driven.
