Abstract

The present invention relates to two bicycles that power driven is advanced of a kind of use.It is by the planetary wheel of a cover ad hoc structure.With two formed speed stacks of propulsion source, bicycle is advanced with fast speeds.Two propulsions source do not disturb mutually and can make its speed mutual superposition.Give full play to people's dynamic role on the one hand, given full play to the speciality of mechanization on the other hand again.If the cyclist thinks arbitrarily to use wherein a kind of power, then the speed of a motor vehicle reduces half approximately, and is approximate with the speed of common bicycle.

Description

Dual-powered bicycle

The present invention relates to and a kind ofly drive simultaneously, and can make the bicycle of two speed stacks by two power.

Existing Electrical Bicycle is to drive bicycle with simple motor force to advance; Existing motor bike also merely drives motor bike with the power of driving engine and advances.Though they all have foot drive device,, just after electrical motor or driving engine et out of order, just use foot pedal apparatus to drive this car and advance.Even the Electrical Bicycle that has can be ridden driving in electrical motor work, still, this is the synthetic of power.Two power interfere with each other, and net output is separately suppressed mutually.The disadvantage of above-mentioned this car is that it can not give full play to all propulsions source, particularly people, and this is propulsion source simply and easily, fails to give full play of enthusiasm.

One of advantage of existing bicycle is: it can play the effect of taking exercises, and Electrical Bicycle and motor bike, the degree that does not all have bicycle to take exercises is big.For the cyclist can be taken exercises, can reach the purpose of advancing fast again, the present invention designs a kind of by two kinds of propulsions source while bicycle driven.Two propulsions source speed separately makes it stack by a specific planetary gear apparatus, forms the speed of a motor vehicle.One of two kinds of propulsions source are people's foot-operated power.Another propulsion source can be any, for example: electrical motor, spark ignition engine, steam engine, windmill etc.Also can advance by double foot-operated simultaneously this car of driving.The objective of the invention is to: the advantage of comprehensive Electrical Bicycle, motor bike, bicycle, avoid shortcoming separately.Particularly, reduce city noise, add strong man's physical exercise in order to improve city pollution.

The solution of the present invention is finished like this.Fig. 1 is the dual-powered bicycle scheme drawing; Fig. 2 is planetary kinematic sketch of mechanism; Fig. 3 is the scheme drawing of embodiment; Fig. 4 is the handgrip dynamic braking device scheme drawing of holding concurrently.

With reference to Fig. 1, (1) is the handlebar stop mechanism of holding concurrently, and (2) are the braking steel wires, and (3) are battery compartment or fuel tank (difference on propulsion source decide), and (4) are recoil springs, and in order to the raising buffering effect, (5) are the planetary wheel storehouses, and (7) are power bins.More than three storehouses be integrated, be positioned at bicycle middle part.(6) be pedal parts.Figure (2) is the kinematic sketch of sun and planet gear.Among this figure, the moment conduction sequence between its gear has two-way.One the tunnel is: straight gear (8) is a driving wheel, and it can be by drivings such as electrical motor, spark ignition engines.Straight gear (8) drives straight gear (10), and straight gear (10) is an one with bevel type gear (9), rotates synchronously.Bevel gear (9) drives planetary wheel (16) and (12) autobiography, and the autobiography of (16) and (12), it drives bevel gear (15) rotation again.(15) be one with sprocket wheel (14), rotation synchronously.Sprocket wheel (14) drives chain movement.Chain drives the flywheel rotation, drives bicycle and advances.Another road is: foot-operated (11) make center cross (13) rotation drive planetary wheel (16) and (12) and do the planet running.Because the moment that (9) and (10) have electrical motor to produce, the moment of this moment and center cross is reverse, and two formed rotating speeds of moment are on the planetary wheel that is added to (16) and (12).(16) and (12) drive (15) and (14) rotation, (14) drive chain, chain drives flywheel and rotates bicycle is advanced.

During use, when not wanting to use direct motor drive, handlebar (1) forwards the motor braking position to.Cut off the power supply of electrical motor this moment.At this moment, braking steel wire (2) discharges the pulling force of banking pin (29), and spring (28) is pushed banking pin (29) the tooth root position of straight gear (10) to, and gear (10) can not be rotated.At this moment, have only foot-operated power that car is advanced.Otherwise, if do not want that driving bicycle with foot-operated power advances, can make both feet static, thereby center cross (13) is remained static, simultaneously, handlebar (1) is rotated forward.At this moment, spring (35) moves right banking pin (34), and braking steel wire (2) is tightened up, thereby has overcome the power of spring (28), makes banking pin (29) break away from straight gear (10), frees the braking that this is taken turns.Meanwhile, the power connection of electrical motor makes the electrical motor rotation, passes to the flywheel rotation at last, and bicycle is advanced.

Embodiment:

Fig. 1 is a kind of dual-powered bicycle scheme drawing.It is to improve to form on traditional bicycle basis.Increased recoil spring (4), to increase its cushion characteristic.Recoil spring (4) is stuck on the step of vertical beam inwall, and saddle is supported in the upper end.When people's body weight was added on the saddle, spring (4) was compressed about 1/3rd.When car top wavefront advanced, people's acceleration due to gravity moved spring (4) in 2/3rds action radius, thereby reaches the impulsive force of mitigation to front fork and back vent.

The key mechanism of this car: planetary wheel is contained in middle shaft position.(3) be the battery logical sequence, it and gear logical sequence (5) and electrical motor logical sequence (7) are integrated, and are connected with horizontal, vertical two beams of bicycle.(2) be the braking steel wire, it leads to banking pin (29) tail end from the inwall of right handlebar through the cant beam inwall.

Fig. 3 is the scheme drawing of sun and planet gear.(17) be DC motor, it is the propulsion source of gear (8).Gear (10) and (9) are integrated.Gear (14) and (15) are integrated.Planetary wheel (16) and (12) are clipped in the middle of them.Above-mentioned four gears are contained in four ends of center cross with radial thrust bearing (22).The umbellate form end face of each gear has a ring-like arc groove, has corresponding arc groove at the step place of center cross, the steel ball of packing into (21) simultaneously.When fastening nut (23), four gears and center cross all can rotate flexibly.Banking pin (29) is contained on the gear logical sequence shell (19).Banking pin (29) is supported by spring (28), and making it can stuck gear (10).

With reference to Fig. 4: the end of braking steel wire (2) is connected with banking pin (34).(35) be spring, its elastic force is greater than the elastic force of spring (28), to guarantee that banking pin (29) and gear (10) are broken away from.(33) be a boss of right handgrip inwall, withstand (34), make (34) overcome the elastic force of spring (35) along the motion of direction shown in the arrow (37) when angle of boss rotation.At this moment, because the elastic force of spring (28) advances banking pin (29) stuck gear (10).At this moment, the car list drives with foot-operated power and advances.Bearing (25) adopts radial ball bearing, and it cooperates with shell by bearing cap shim (24).(30) be the transverse tube wall, (32) are jacket wall.

In order to make the gear logical sequence that enough intensity and rigidity be arranged, a thicker dividing plate (18) is arranged between electrical motor logical sequence and gear logical sequence.Electrical motor is fixed on this dividing plate.Crank (26) in the foot-operated parts of bicycle cooperates with center cross, and is the same with the fit system of common bicycle.The battery logical sequence is arranged at the top of electrical motor logical sequence, and a group storage battery is housed, and is furnished with a cover charging unit simultaneously.

After this kind bicycle is put on market, surely can certain impact be arranged to existing vehicles market. Because its sale price is moderate, speed is moderate, and is safe and reliable, do not pollute, and noise is little, and operation cost is low, keeps in repair also very convenient.
