Description

 Specification

 Bicycles and autos with energy-saving wheel drive mechanism: z-wheeler Detailed description of the invention

 Industrial applications

 The present invention relates to a bicycle and a motorcycle. That is, between the axle of the drive wheels and the tires, a new rotational power transmission mechanism, which is fixed concentrically with the axle and is provided with a ring chain, and drives it at the uppermost portion inside the ring chain, is provided with a body drive. Energy is reduced to less than half.

 INDUSTRIAL APPLICABILITY The present invention can be used for all motorcycles and tricycles that transmit the power of the drive wheels by a chain.

 Conventional technology

 Conventionally, there is a speed switchable bicycle that increases the driving force by increasing the number of rotations of the pedal and climbs a hill.However, this is based on the law of conservation of energy and the amount of work runs on level ground. In the same way, energy saving has not been achieved, and in the case of motorcycles, measures to improve the efficiency of the two-cylinder engine and the efficiency of the power transmission system have been considered, but none of these were sufficient. Is hard to say

 Problems to be solved by the invention

 It is an object of the present invention to enable a bicycle to climb at the same speed with the same speed on a slope and the effort on a flat ground as if it were running on a flat ground. The purpose is to halve petroleum energy (gasoline, etc.) used for driving.

 Means for solving the problem

Conventional bicycles and motorcycles travel by transmitting rotational power to the axle center of a drive wheel and forcibly rotating the wheel. The present invention renews the concept of the conventional wheel rotation power transmission mechanism. In other words, a wheel is provided with a ring chain concentric with the wheel, and a sprocket engaged with the ring chain at the uppermost portion of the ring chain is rotated, whereby the wheel is continuously turned over and run. According to the present invention, the number of rotations of the sprocket is large because the ring chain is rotated by the sprocket, but the torque required for the sprocket is extremely small because the sprocket diameter is small compared to the wheel outer diameter. It can be driven. That is, attention is paid to the fact that the total driving energy can be reduced because the torque decrease is extremely large as compared with the increase in the rotational speed.

 Next, FIGS. 10 and 11 will be described. Reference numeral 21h denotes a ring chain holding ring for fixing the ring chain 56 concentrically to the axle 9k with the bolt 9h on the disk 9i.

According to the above-described embodiment, taking the cases of FIGS. 8 and 9 as an example, the conventional wheel can be used as it is and the ringe chain can be reduced. Also, in the case of Figs. 10 and 11, the attachment of the ring chain retaining ring is extremely easy. O Next, an analysis of the energy-saving wheel drive mechanism of the present invention will be described with reference to FIGS. 12, 13, 14, and 15. Fig. 12 is an example of a conventional bicycle, Fig. 13 is an example of a bicycle having an energy-saving wheel drive mechanism according to the present invention, and Fig. 14 is a bicycle having an energy-saving wheel drive mechanism according to the present invention when climbing a slope having a small slope. It is an analysis figure. The dimensions are determined as shown in Fig. 12, Fig. 13, and Fig. 14.

Assuming that the force applied to the pedal ¹³ when driving a conventional bicycle is P, the total weight of the vehicle body including the driver's weight is W, and the rolling friction coefficient of the tire is N, the number of tire revolutions during running is N, the sprocket 11 (The acting torque T _v rotation speed Ν _υenergy Ε is obtained as follows.

Ττ = d, -Wf / d ₂ : T.

Ντ = da- / d, · 2) ρ _{1 =} c ^ 'Wf pat d ₂ ) ……-·: ¾;

Also, if the angular velocity of sprocket 11 is _ωι

—One, _ωι = 2TT -CJ ₂ 'N / (

Therefore

 Ε, == aTT'ds'N'd W'f / (SO'c ^ 'ds) ④

In the case of a bicycle having the energy-saving wheel drive mechanism according to the present invention, the following applies.

T ₃ = d ₃ .d ₄ .Wf / {d ₅ (D ₀ + D)]

N ₃ = d ₅ -DN / (d ₃ -d ₄ )

P ₂ = d ₃ -d ₄ -Wf / {lrd _5- (D ₀ + D)] -⑦

Also, if the angular velocity of sprocket 24 is ω3

Ε ₂ ⁼ Τ ₃ · ω ₃

On the other hand, ω ₃ = 27r'd ₅ 'D'N / (60'd ₂ -cJ ₄ )

Accordingly

Ε ₂ = 2ττ -dg-DN-da-^-Wf / [60-d ₃ -d ₄ -cl _5- (. D ₀ + D)] From the above, the energy ratio 77 with the conventional vehicle at the same body weight and the same speed is obtained.

_ 27r'd ₅ 'D'N'd ₃ .d ₄ -Wf / i60'd ₃ -d ₄ ' d ₅ '(D ₀ + D)}

= 1 / (1+ D ₀ / D) ⑨.

This means that since D ₀ / D> 1, 77> 2. The smaller the diameter D of the ring chain, the higher the efficiency.

Further, the conventional wheel and the present invention car and the same rotational speed to turn the pedals at Les,. And, in order to equalize the running speed may be determined the dimensions of the d ₃ so as to satisfy the following equation.

d ₃ = d, -d ₅ -D / (d ₂ -d ₄ ): fO)

 The ratio of the pedaling force P at the same speed and the same vehicle weight is as follows.

= P ₂ / P,

= d ₂ -d ₃ -d ₄ / (d ^ ds-C D ₀ + D)]: 1J;

 On the other hand, under the same speed and the same vehicle weight, when climbing a hill with an inclination angle of 0, the pedaling force P3 of the vehicle of the present invention is as follows.

P ₃ = d ₃ -d ₄ -W- [f-cos0 + (D _o / 2) -sin ₀ } / [ld _5- (D ₀ -j- D)}; 1¾ Figure "15.

Here, the following conditions, which are examples, are used.

_{125mm, d 2 = 4> 55mm} , d 3 == <t> 380mm, d 4 = d 1 = Φ 125mm d 5 = d 2 = t> 55mm, D = 380mm D. = 0) 660mm, 1 = 170mm

 , W = 80 kg, f = 20mm

From the above conditions, the following is obtained.

 Ρτ = 20 kg-⑩

P ₃ = 7.8 (cos9 +.16.5 sin)) ¾).

FIG. 15 illustrates the equation: β: ′.

As can be seen from FIG. 15, since the slope of a normal slope is 5 degrees or less, the bicycle according to the present invention can easily climb up a slope as if it were running on level ground. Also, on a 10-degree slope, the force applied to the pedal

It weighs less than 30 kg and there is no need to get off the bicycle. Next, another embodiment will be described with reference to FIGS.

FIG. 16 is an explanatory view showing the entire view of another embodiment. Fig. 17 and Fig. 18 show the X-X cross section of Fig. 16 and show the spoke type and disk type wheels conventionally used.

First, the structure will be described. The pedal 13, crank 12, sprocket 11, and chain 10 are exactly the same as the conventional car. H: The power of the chain 10 is transmitted to the sprocket 8. The sprocket 8 is integrated with the other sprocket 72, and is rotatable on the axle shaft via a bearing 72a.

The sprocket 77 engaging with the ring chain 21, the one-way clutch 22b, the sprocket 76, the shaft 23, and the frame 20f are as described above. 78 is a sprocket with a chain? It links 2 76. 74 is a sprocket for preventing the chain 78 from being loosened on the shaft 73 on the frame 20f.

Here, 29 indicates a conventional brake device.

 According to this structure, the number of teeth of the sprocket can be easily set according to the purpose of use.

Also, there is an advantage that a conventional car can be easily modified.
