New description: [New technology field] This creation department is about exercise bikes, especially an exercise bike that uses a planetary transmission to drive the flywheel. [Prior Art] The magnetic exercise bicycle is one of the most popular fitness equipments in recent years. It mainly uses magnetic control to change the pedal resistance to achieve the fitness effect. As shown in Fig. 1, a conventional magnetic exercise bicycle 10 is shown. The magnetic drive body 10 has a body 11 , and a transmission wheel 12 and a weight wheel 13 are respectively disposed at the front and the rear ends of the frame body 11 , and the center of each side of the transmission wheel 12 A pedal 121 is connected to the wheel 13 and a wheel belt I4 ′ around the wheel of the transmission wheel 12 to drive the transmission wheel 12 to rotate by stepping on the two pedals 121 , and then the belt 13 is rotated by the belt 14 . And the weighting wheel 13 is disposed on the side of the roller control device 15, and the magnetic control device 15 is in contact with the weight wheel 13, thereby changing the rotational resistance of the weight wheel 13 by its magnetic force. However, if the aforementioned magnetron exercise vehicle 10 needs to increase the speed ratio of its transmission wheel 12 and the weight wheel 13, it must be achieved by increasing the transmission wheel 12, but also increasing the overall volume of the magnetron exercise vehicle 10, not only increasing manufacturing. The cost also causes inconvenience in assembly work, so it is necessary to further improve it. [New content] In view of this, the creator of this case has carefully studied and accumulated years of experience in the research and development of fitness car related products. After several trials and trials, he finally created a planetary transmission device for exercise bikes. . The purpose of the present invention is to provide a planetary transmission device of the type of exercise vehicle, which mainly wears a transmission shaft connected to the pedal to a fixed gear that does not rotate, a planetary gear that revolves around the fixed gear and rotates at the same time. The increase is: the drive gear plate of the turn-in ratio and a counterweight wheel that is driven by the drive gear plate, so that the fixed gear and the fixed plate for the drive shaft are fixed to the exercise frame body. (4) When moving, the planetary record is the end of the drive shaft and the drive shaft is driven by the dry, so that the fixed gear revolves, and a chain is wrapped around the S > star gear and the fixed gear 'and the belt is wrapped around In the planetary gears and. The drive gear plate enables the planetary record to revolve and rotate at the same time, thereby driving the drive gear to drive the weight wheel to rotate. By means of the above-mentioned planetary transmission device, the exercise bicycle can achieve the purpose of increasing the speed ratio without increasing the size of its own heavy wheel, which is not only suitable for the size of the part, but also facilitates the assembly work. Lanji's has the advantage of reducing the overall cost of the body. The techniques, means, and methods used to achieve the above objectives in this creation are described in detail with reference to the drawings.
