Description

Bicycle accelerator power driving device

본 발명은 자전거 가속동력장치에 관한 것으로 상세하게는 자전거 뒤바퀴 중심축상에 설치하여, 주행시, 구동바퀴의 중심액슬축과 연관되어 구동바퀴의 회전력을 가속시켜 줄 수 있도록 하여, 적은 힘으로 자전거 속도를 쉽게 낼수 있도록 한, 주행속도 향상을 위한 자전거용 가속장치에 관한 것이다.The present invention relates to a bicycle acceleration power unit in detail installed on the central axis of the bicycle rear wheel, in connection with the central axle shaft of the driving wheel to accelerate the rotational force of the driving wheel when driving, bicycle speed with a small force The present invention relates to an accelerator for a bicycle for improving driving speed, which makes it easier to produce.

자전거는 교통수단, 운반수단으로 주로 이용되지만, 최근에는 레저활동 및 운동을 통한 신체단련 목적으로도 많이 사용되고 있다.Bicycles are mainly used as a means of transportation and transportation, but recently they are also used for the purpose of physical fitness through leisure activities and sports.

그러나, 자전거는 오르막, 평지, 내리막등 다양한 도로, 운전조건에 따라 소요되는 힘에 많은 차이가 있다.However, there are many differences in the power required for bicycles depending on various roads and driving conditions such as uphill, flat, and downhill.

출발,가속,오르막일 경우, 자전거를 운행하기 위해 많은 힘이 필요하게 됨에 힘을 덜기 위해 저속으로 변속하는 것이 필요하게 되어, 폐달쪽 구동체인 기어 및 구동바퀴쪽에 각기 직경이 다른 다단의 체인기어를 두어 체인의 위치를 변경할 수 있는 변속장치가 적용 설치되어 다양한 속도 변화를 할 수 있도록 하고 있다.When starting, accelerating, or uphill, it requires a lot of power to operate the bicycle, so it is necessary to shift at a low speed to reduce the power. The transmission is installed to change the position of the chain so that various speeds can be changed.

아무리, 변속장치를 통한 속도변화를 하더라도, 자전거 이용자의 체중,자전거 본체 하중, 체인기어의 맞물리는 부하를 줄일 수는 없다,However, even if the speed change through the transmission does not reduce the weight of the bicycle user, the weight of the bicycle body and the meshing load of the chain gear,

잦은 변속은, 변속장치의 고장을 유발하기 쉽고 변속중 속도감이 떨어지기에, 자전거에 걸리는 부하를 외부전원을 공급하여 자전거 이용자의 힘의 부담을 줄이는 전기자전거도 있으나, 외부전원의 주기적 교체라는 불편과, 충전이라는 불편과, 자전거 가격의 고가라는 점이 수반되어 자전거 운동이라는 사용의 묘미를 감소시키는 문제점이 있게 된다.Frequent shifting is easy to cause a breakdown of the gearbox, and the sense of speed decreases during shifting.There are also electric bicycles that reduce the burden on the bicycle users by supplying external power to the load on the bicycle. In connection with the inconvenience of charging and the high price of the bicycle, there is a problem of reducing the beauty of the use of bicycle exercise.

이러한, 문제점을 개선하기 위해 대한민국 등록실용신안 20-418803호(발명의 명칭: 유성기어장치를 사용한 자전거 구동장치)가 개시된 바 있다.In order to improve such a problem, Korean Utility Model Registration No. 20-418803 (name of the invention: a bicycle driving device using a planetary gear device) has been disclosed.

즉, 상기 등록실용신안은 유성기어장치를 폐달측에 적용한 것으로 상기와 같은 구조는, 세발자전거, 외발자전거, 오디너리형 자전거등과 같이 폐달의 회전 구동되는 축상에 유성기어장치가 설치되기 때문에, 실질적 주동력은 폐달에서만 이뤄져 실질적 속도향상이 그다지 크지 못하다는 단점이 있어 다양한 가속장치의 조합으로, 지역 도로 특성에 맞는, 여러 가지 형태의 자전거를 만들 수 없다는 단점이 있다.That is, the utility model is a planetary gear device applied to the lung side, such a structure, since the planetary gear device is installed on the axis of rotation of the lung moon such as tricycle, unicycle, ordinary bicycle, Since the main power is made only in the lung moon, the actual speed increase is not so great. As a result of the combination of various accelerators, there is a disadvantage in that various types of bicycles can not be made in accordance with local road characteristics.

따라서, 본 발명의 주 목적은, 자전거의 다양한 운전조건에 소요되는 힘이 최소화되도록 자전거의 뒤바퀴 구동축상에 다양한 가속장치를 간단하게 설치하여, 자전거의 속도가 쉽게 가속되도록 하는 자전거용 동력구동장치를 제공함으로서, 지역도로특성 및 이용목적에 맞는 자전거를 선택할 폭을 넓혀 자전거 이용자의 재미를 증가시키는 것을 제공하는 데 있다.Therefore, the main object of the present invention, by simply installing a variety of accelerators on the rear wheel drive shaft of the bicycle so as to minimize the force required for various driving conditions of the bicycle, the bicycle power drive device to easily accelerate the speed of the bicycle By providing a wider choice of bikes that meet the characteristics of the road and the purpose of the purpose to increase the fun of the bike users.

According to the combination ratio of the number of teeth, the number of teeth of the sun gear, and the number of teeth of the planetary gear, it is a means for shifting the rotating body by the principle of forward, reverse rotation, acceleration, and deceleration, to fix the sun gear of the present invention and input the planetary gear When the ring gear is output, the acceleration output in the same direction (forward rotation) can be obtained based on the coupling ratio of the gears.

Rotational force increases the rotational force in the housing 51, which helps the housing to rotate faster, more quickly and easily rotate the housing, and also the rotational force of the planetary gear 23 through the ring gear 25 connected to the housing As a result, the multi-speed transmission gear 21 via the planetary gear carrier 24 and the general chain gear can be easily rotated while increasing the speed.
