Description

A magnet using an magnet's magnetic force.

The present invention relates to a bicycle acceleration power device, characterized in that by installing an acceleration power driving device using a magnetic force of a magnet in a portion associated with a bicycle pedal, the rotational force of the driving wheel is increased to improve driving speed and save the pedaling force of a bicycle user. will be.

Bicycles are mainly used as a means of transportation, but recently, they are also widely used for the purpose of training through leisure activities and exercise.

In general, a bicycle rotates a pedal to rotate the central axis, thereby generating a power source, and power is transmitted through the chain to the rear wheel drive shaft through a chainring connected to the central shaft to obtain propulsion. In other words, driving by using the force of the pedaling of the bicycle user, there is no great difficulty in driving on flat ground, but when driving on slopes, etc., a lot of power is required.

Recently, in order to increase the speed of the bicycle, general bicycles have multi-stage chain gears with different diameters on the drive chain ring and the rear wheel side of the pedal, so that the position of the chain can be changed with the transmission, so that various speeds can be achieved. and. The electric bicycle uses the power of the battery to drive the electric motor so that it can speed up.

In order to increase the speed, the pedal should be pressed quickly and rotated quickly, and the drive sprocket contacting the pedal should be large and the rear wheel chain gear should be small. In addition, in order to drive on a hill or a sloped road, the pedal-side drive sprocket is small and the rear wheel chain gear is large to consume less power.

In this case, when driving the same distance, the existing bicycle is inconvenient to perform frequent shifting, and it is easy to cause shifting troubles.The electric bicycle power transmission device increases the weight with an electric coil, reducer, etc., and increases the weight with a battery. That is, it needs to be charged, and in that it requires electricity when charging, it is inconsistent with the most environmentally friendly transportation.

In order to solve these problems, the present invention relates to an acceleration power driving device using a permanent magnet, a central axis, and an auxiliary axis, and the applicant of the present invention has applied for a domestic patent application number 10-2019-0000048 (2019. 01. 02). However, the above-mentioned application is combined with the central axis and the auxiliary axis, and the price of the C-shaped magnet that increases the rotational force when rotating is expensive, the fact that the generation of the rotating power is only twice when the pedal is rotated, and the arrangement of the magnetic regulator There is a problem in that the furnace housing space becomes large.

The present invention is intended to solve and improve the above-mentioned drawbacks, by changing the speed by the interaction between the magnetic forces of two rotating shaft magnets by combining two rotating shafts with permanent magnets in the housing, and rotating shaft speed on a certain part of the inner surface of the housing. By placing the magnets of the stator to increase the position in two places, the magnets of the two rotating shafts and the stator magnets generate an acceleration force by the mutual pushing and pulling interaction, thereby continuously rotating by the rotating gear meshed with the two rotating shafts. It is intended to complement and improve the disadvantages of the previously proposed invention by installing an acceleration power driving device that reduces the consumption of the stepping force and transmits the increased rotational force to the rear wheel driven sprocket through the chain through the pedal-side drive sprocket.

In the case of a conventional bicycle, the drive sprocket coupled to the central axis during one revolution of the pedal also has a constant rotation, such as only one revolution, or the accelerating power driving apparatus of the present invention for achieving the above problem, the mutual interaction of the magnetic force pushing and pulling around the rotating gear body The number of rotating rotors can be composed of two central and auxiliary shafts, and a stator that generates accelerated rotational force by interacting with the rotor can be installed in two places on the inside of the housing, and is installed on the left and right sides of the rotating gear. Since the number of rotor blades can also be composed of 2, 3, 4, 5, and 6, the rotational force is continuously generated when the pedal is driven.If a drive sprocket is connected to one end of the pedal center shaft, the increased rotational force will result in rear wheel rotation. The speed is improved by being transmitted to the driven sprocket, and the force required for pedaling the bicycle can also be saved.

By using the accelerator power driving system using the permanent magnet's magnetic force as a bicycle power source, the speed increases and the torque is increased even when the pedal operates with the same force, so that you can easily climb slopes, etc., and the bike user's weight and gear Depending on the load, the weight of the bicycle body, road driving conditions, and the purpose of using the bicycle, the number of rotor blades can be adjusted, or the magnetic strength of the magnets coupled to the rotor and stator can be changed, so speed can be adjusted without using a planetary gear. It is easy to make and can make customized bicycles suitable for bicycle users, so you can get the pleasure of leisure and bicycle travel hobby.

날개의 자석의 밀고 당기는 자력작용으로 회전력이 발생하게 된다. 도5의 사례도와 같이 회전자날개수를 3개로 할 경우 중심축이 360도 회전하는 사이에 회전력이 3번 발생한다. 그러나, 회전하는 중심축의 회전자날개와 보조축의 회전자날개가 히우징본체에 있는 고정자 자석에 가까이 접근하면 각축의 회전자날개가 고정자자석에서 떨어지지 않으려는 자력의 작용으로 응력이 쌓이게되나 기어체의 회전힘으로 고정자 자석과 떨어지지 않으려는 회전자날개의 자력 작용을 넘어서면 자력의 밀어내려는 작용으로 가속력이 발생하게 되며 이 상호 작용을 회전기어체를 중심으로 좌

우에서 각각 3회 반복하게 되어 가속력이 발생함으로서 페발밟는 힘이 적게 들고 각축이 빠르게 회전하게 된다.When the central shaft rotating gear rotates due to the action of the pedal's exit room, the central shaft rotating gear 31 and the auxiliary shaft rotating gear 32 engaged with the gear rotate together. If the gear teeth of each rotating gear are equal, the center Rotor blade and auxiliary shaft rotor on the shaft rotation gear

Rotational force is generated by the magnetic action of pushing and pulling the magnet of the wing. When the number of rotor blades is 3, as in the example of FIG. 5, rotational force is generated 3 times while the central axis is rotated 360 degrees. However, if the rotor blades of the rotating central axis and the rotor blades of the auxiliary shaft are close to the stator magnets in the housing, the stress of the rotor blades of each axis will accumulate under the action of the magnetic force that will not fall off the stator magnet, but the stress will accumulate. If it exceeds the magnetic force action of the rotor blade that does not fall off from the stator magnet due to the rotational force, an acceleration force is generated by the action of pushing the magnetic force, and this interaction is left around the rotating gear.

Since it is repeated 3 times in the right, each accelerating force is generated, so the stepping force is low and each axis is rotated quickly.

The principle of this is that the number of rotor blades is 2 or 4, or it works on the same principle, but the strength of the rotating torque can be changed.
