Abstract

The utility model relates to a flywheel power-assisted cycle, comprising a front wheel, a back wheel and a complete machine frame. The utility model is characterized in that a lever-typed driving mechanism formed by a foot pedal, a boosting rod, a connecting rod and a crankshaft connected with a centre shaft is adopted, and a flywheel with large quality energy storage, which is on one side of a floral disk and is driven by the centre shaft, is arranged. The utility model can significantly save labour force compared with manpower bicycles with the prior art, and can run fast. The utility model has the advantages of novel structure and easy use. The utility model can make up and down reciprocal motion by users boosting on the pedal to complete the drive.

Description

Flywheel power-assisted cycle

The utility model relates to bicycle, more particularly, be a kind ofly comprise forward and backward wheel and complete machine vehicle frame, be the bicycle of power with the manpower.

Be the bicycle of power with the manpower in the prior art, comprise not variable speed bicycle that only has a kind of fixed drive ratio and variable speed bicycle, all exist effort, slow-footed problem with transformable several transmitting ratios.

The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of laborsaving, fireballing bicycle and man is provided.

The purpose of this utility model is realized by following technical scheme.

The utility model comprises forward and backward wheel and complete machine vehicle frame, of the present utility model being characterised in that:

A, employing lever driver train, this mechanism comprises and is installed in the foot-operated of boosting-rod end, and the boosting-rod other end connects bent axle by connecting rod, and described bent axle is positioned at the axis two ends, and be connected as a single entity with the axis that drives floral disc, the both ends of described bent axle are bearing on the vehicle frame in the crankshaft hole;

B, big quality energy storage flywheel is set, described flywheel gear is positioned at floral disc one side on axis;

C, on rear wheel, be equipped with forward and reverse two and fly, and on the trailing wheel vehicle frame of relevant position, fixedly mount and can be used to chain at described forward and reverse two load push-pulls that fly reversing of position.

Compare prior art, the utlity model has following advantage:

The utility model is by adopting lever actuated mechanism and big quality energy storage flywheel being set, not only can reach laborsaving, fast speed purpose, and, owing to adopt lever to drive, the user is by afterburning on riding, make it make upper and lower crank motion, just can finish driving, its novel structure, easy to use.

Fig. 1 looks scheme drawing for the utility model master.

Fig. 2 is the utility model schematic rear view.

Fig. 3 is the utility model axis structural representation.

By the following examples, and the structure accompanying drawing, the utility model is further described.

Embodiment:

Referring to Fig. 1, the lever driver train comprises rides 1, boosting-rod 2, connecting rod 3 and bent axle 4.Foot-operated 1 is installed in the end of boosting-rod 2, and the other end of boosting-rod 2 connects bent axle 4 by connecting rod 3.In the axis structural representation shown in Fig. 3 as can be seen, bent axle 4 is positioned at the two ends of axis 5, and be connected as a single entity with axis 5, the overhang bracket of bent axle 4 is on vehicle frame in the crankshaft hole 6, on axis 5, device has small faceplate 7, flywheel 9 and floral disc 8 from left to right, the anti-inverted flight 10 of device between the end of bent axle 4 and vehicle frame crankshaft hole 6.

In the present embodiment, on the axletree of rear wheel 11, device has three to fly altogether, comprise be positioned at rung bar right side forward and reverse two fly 12 and a forward being positioned at rung bar left side fly 13, constitute two pairs of transmission devices altogether in the bicycle left and right sides, comprise main drive gear that is positioned at rung bar right side and the low speed driving mechanism of another pair that is positioned at rung bar left side.

As shown in Figure 1, main drive gear is to drive forward and reverse two of rear wheels 11 spoke right sides by floral disc 8 by chain 14 to fly 12, fixed installation load push-pull 15 on the trailing wheel vehicle frame of relevant position, load push-pull 15 is used for chain 14 is flown reversing of position on 12 at described forward and reverse two.

As shown in Figure 2, low speed driving mechanism is to drive the power-transfer clutch 17 that is fixed on rear wheel 11 vehicle frames by small faceplate 7 by chain 16, flies 13 by power-transfer clutch 17 by the forward that chain 18 drives rear wheel 11 rung bars left side again.

Load push-pull 15 and power-transfer clutch 17 are the stay-supported operating mode, and its backguy ahead running frame causes handlebar.

In addition, between the axis hole of flywheel 9 and axis 5, install overriding clutch,, and drive flywheel 9 and rotate so that the applied force amount can drive axis 5 by the lever driver train effectively on foot-operated 1; And when stopping to apply external force, flywheel 9 is because inertia is rotated further, and foot-operated 1 keeps static.

The user can hang neutral gear (power-transfer clutch 17 is in and offs normal, and load push-pull 15 is in oppositely chain 14 and flies) with chain earlier before getting on the bus, and flywheel is rotated get on the bus afterwards, subsequently, and the low gear that closes, the inertia of flywheel promptly is utilized.If need, behind the quickening flywheel, push to fast shelves and get final product fast running.When travelling, both feet can alternately be had a rest, and also can have a rest simultaneously, and at this moment the inertia of flywheel is enough to the speed of a motor vehicle that keeps certain.Before the brake, (power-transfer clutch 17 is in and offs normal at first chain to be pushed neutral gear, chain 14 is hung and is oppositely flown), operate forward and backward wheel and stop, make wheel decelerates until stopping operating, at this moment, flywheel keeps rotating, when resetting, the low gear that at first closes can guarantee safety and starting steadily with low speed as transition.When meeting obstacle on the way, can be promptly from promptly closing.

In the present embodiment, simultaneously flywheel can be set and stop,, realize sudden stop so that when needing, directly brake flywheel.
