Abstract

The utility model symmetrically belongs to a power-assisted accelerating bicycle, which is characterized in that two power-assisted accelerators whose positions are adjustable are symmetrically fixed on the second and the forth spokes of a front and a back wheels by screws; the degree of power-assisted force can be freely selected. The utility model has convenient operation, the good balance of wheels and stable ridding; the power-assisted accelerators have multiple shapes; the whole bicycle has shapely configuration.

Description

Power-assisted is quickened bicycle

The utility model relates to bicycle, is that a kind of power-assisted is quickened bicycle.

At present, the bicycle of selling on the market roughly is divided into two kinds: a kind of is bicycle, another kind is a three-wheel vehicle, its structure is basic identical, all be by handlebar, vehicle frame, front fork, front-wheel, front axle, axis, pedal, chain, rear axle, trailing wheel, flywheel, saddle component set-up, these two kinds of bicycles all are two, the old product of the '30s, slow, the effort of riding speed.What had in recent years has loaded onto driving engine, becomes mini-motorcycle, three wheeled motor car, motor bike, still, and self-propelled vehicle oil consumption height, contaminated environment, maintenance trouble.

The purpose of this utility model provides a kind of power-assisted and quickens bicycle, to solve slow, the effort of existing bicycle riding speed; And self-propelled vehicle oil consumption height, contaminated environment, maintenance troublesome problem.

The purpose of this utility model is achieved in that this bicycle is by handlebar, vehicle frame, front fork, front-wheel, front axle, axis, pedal, chain, rear axle, trailing wheel, flywheel, saddle component set-up, on 2,4 spoke of front and rear wheel, by intrinsic two the power-assisted accelerators of screw symmetry.

Power-assisted accelerator cylindricality spherical in shape, cylindrical, stupefied, taper shape, stupefied taper or be berrette file shape, flat rhombus, oblateness, flat ellipse cast, deltiod or curved flat cuboid, the flat stupefied cylinder of arc.

This utility model compared with prior art has the following advantages: (1) is faster than existing bicycle riding speed, can improve 2-3 doubly, and laborsaving; Fuel-efficient, free from environmental pollution than self-propelled vehicle; (2) on spoke, adjustable positions can freely be selected the power-assisted size to the power-assisted accelerator, and is easy to use by screw retention; (3) power-assisted accelerator symmetry is installed, and the wheel balance degree is good, rides steadily; (4) power-assisted accelerator shape is many, makes bicycle more elegant in appearance.

Be described further below in conjunction with accompanying drawing:

Fig. 1, power-assisted are quickened bicycle structural representation (bicycle is an example);

Fig. 2, power-assisted accelerator structure scheme drawing (sphere);

Fig. 3, power-assisted accelerator front view (prolate is square);

Fig. 4, A-A cutaway view.

Among Fig. 1-4: handlebar (1), front fork (3), vehicle frame (2), front-wheel (5), front fender (4), front axle (6), axis (7), pedal (8), chain (9), rear axle (10), flywheel (11), trailing wheel (12), back mud plate (13), clothes hanger (14), saddle (15) are identical with the prior art shape and structure, on 2,4 spoke (16) of front and back wheel, by screw symmetry intrinsic two power-assisted accelerators (17).Power-assisted accelerator (17) adopts steel, iron, copper, lead metal to make, cylindricality spherical in shape, cylindrical, stupefied, taper shape or be berrette file shape, flat rhombus, oblateness, flat ellipse, deltiod or curved flat cuboid, the flat stupefied cylinder of arc; Power-assisted accelerator (17) axially or radially is provided with the spoke hole (18) that matches with spoke (16), vertical 1-2 the screw hole (19) that be provided with spoke hole (18).Power-assisted accelerator (17) is spherical in shape when maybe needing to be fixed on the spoke as shown in Figure 2: the cylindrical void that is open to traffic (18), a 1-2 screw hole (19) are arranged on the power-assisted accelerator; When needs are fixed on two spoke, two spoke holes (18) are arranged on the power-assisted accelerator, spoke hole (18) match with spoke, can move up and down along spoke, and corresponding every spoke is provided with 1-2 screw hole (19); If when adopting lead material to make, reliable clamping plate, screw clamping are on spoke.

Description of operation: bicycle can be only installed on two power-assisted accelerators (17) or each wheel all symmetry in symmetry on the wheel two power-assisted accelerators is installed, to three-wheel vehicle can be only on two trailing wheels respectively symmetry symmetry is installed on two power-assisted accelerators (17) or the front and rear wheel all two power-assisted accelerators (17) is installed.The power-assisted accelerator can improve the speed of a motor vehicle, reduce the power of pedaling by its inertia after wheel runs.

Claims (2)

1, a kind of power-assisted acceleration bicycle is by handlebar (1), vehicle frame (2), front fork (3), front-wheel (5), front axle (6), axis (7), pedal (8), chain (9), rear axle (10), trailing wheel (12), flywheel (11), saddle (15) component set-up, it is characterized in that: go up by screw symmetry intrinsic two power-assisted accelerators (17) at 2,4 spoke (16) of front and rear wheel.

2, power-assisted according to claim 1 is quickened bicycle, it is characterized in that: power-assisted accelerator (17) cylindricality spherical in shape, cylindrical, stupefied, taper shape, stupefied taper or be that berrette file shape, flat rhombus, oblateness, flat ellipse, deltiod or curved prolate are square, the flat stupefied cylinder of arc.
