Description
本發明係關於一種自行車，特別是關於一種自行車之飛輪裝置。 The present invention relates to a bicycle, and more particularly to a bicycle flywheel device.
自行車(又稱為腳踏車)是一種以人力踩踏踏板的小型車輛，其通常具有一前一後連接於車架的二個輪子。自行車的車速主要是由騎士踩踏踏板所提供的助力以及煞車所造成的阻力來決定。 A bicycle (also known as a bicycle) is a small vehicle that pedals a pedal with a human hand, which typically has two wheels that are attached to the frame one after the other. The speed of the bicycle is mainly determined by the assist provided by the Cavalier pedaling and the resistance caused by the brakes.
自行車平時在行進時可依靠車身與騎士的慣性以及因地面傾斜而提供的行進方向上的重力分量來替騎士省力。但若遇到上坡、逆風等因素或是緊急情況而造成自行車減速或停止之後，則必須重新費力踏車方能使自行車回復到原本的速度。 The bicycle usually relies on the inertia of the body and the knight and the gravity component in the direction of travel provided by the tilt of the ground while traveling. However, if the bicycle is slowed down or stopped due to factors such as uphill, headwind, or an emergency, it is necessary to re-train the bicycle to return the bicycle to its original speed.
另外，一但自行車變為低速行進或停止時，會因不穩定而使車身搖擺或是向左右傾斜，而很有可能使騎士因此跌倒或是與兩側的車輛或行人發生擦撞而受傷。 In addition, once the bicycle is turned to a low speed or stopped, the body may be swayed or tilted to the left and right due to instability, and it is very likely that the knight may fall or be injured by collision with vehicles or pedestrians on both sides.
鑑於以上所述，習知自行車在起步及提速時需騎士花費相當的力量來踩踏，並且在低速或停止時會出現車身不穩的情況。 In view of the above, the conventional bicycle requires the knight to spend considerable force to step on the pedal when starting and speeding up, and the vehicle body may be unstable at low speed or stop.

Similarly, the output ratchet 242 connects the flywheel mechanism 21 and the active wheel 12 through the release shifting assembly 232 such that when the flywheel mechanism 21 releases energy to the active wheel 12, the speed of the active wheel 12 does not become faster. Instead, energy is transmitted back to the flywheel mechanism 21 by the active wheel 12.
藉由上述結構，如第2a圖所示，在欲減速該自行車1時，經操作該離合機構22而使該主動車輪12通過該變速機構的該儲能變速組件231連接該飛輪機構21。藉此，該主動車輪12之旋轉動能通過該儲能變速組件231傳動至該飛輪機構21，使該主動車輪12因旋轉動能減少而轉速下降，從而降低該自行車1之行進速度。 With the above configuration, as shown in Fig. 2a, when the bicycle 1 is to be decelerated, the clutch mechanism 22 is operated to connect the driving wheel 12 to the flywheel mechanism 21 via the energy storage shifting unit 231 of the shifting mechanism. Thereby, the rotational kinetic energy of the driving wheel 12 is transmitted to the flywheel mechanism 21 through the energy storage shifting unit 231, so that the rotational speed of the driving wheel 12 is reduced due to the reduction of the rotational kinetic energy, thereby reducing the traveling speed of the bicycle 1.
如第2b圖所示，在該自行車1為低速或停止時，則經操作該離合機構22而斷開該主動車輪12與該飛輪機構21之間的連接。藉此，即便在該主動車輪12及該從動車輪13為靜止的情況中，藉由該飛輪機構21旋轉的角動量，仍可使該自行車1易於保持穩定。 As shown in Fig. 2b, when the bicycle 1 is at a low speed or stopped, the clutch mechanism 22 is operated to disconnect the driving wheel 12 from the flywheel mechanism 21. Thereby, even in the case where the driving wheel 12 and the driven wheel 13 are stationary, the bicycle 1 can be easily stabilized by the angular momentum of the rotation of the flywheel mechanism 21.
如第2c圖所示，在該自行車1為加速或起步時，則經操作該離合機構22而使該飛輪機構21通過該變速機構的該釋能變速組件232連接該主動車輪12。藉此，該飛輪機構21之旋轉動能通過該釋能變速組件232傳動至該主動車輪12，使該主動車輪12因旋轉動能增加而轉速上升，從而提升該自行車1之行進速度或是幫助該自行車1自停止狀態起步。 As shown in Fig. 2c, when the bicycle 1 is accelerating or starting, the clutch mechanism 21 is operated to connect the flywheel mechanism 21 to the active wheel 12 via the release shifting assembly 232 of the shifting mechanism. Thereby, the rotational kinetic energy of the flywheel mechanism 21 is transmitted to the driving wheel 12 through the release shifting assembly 232, so that the driving wheel 12 increases in rotational speed due to an increase in rotational kinetic energy, thereby increasing the traveling speed of the bicycle 1 or assisting the bicycle. 1 Start from the stop state.
