However, when the resistance wheel 70 is controlled to control the resistance, the wire motor 71 controls the wire cutter 72 to pull the magnet through the radiation 74, and the precision of production is not easily controlled, so the wire is pulled. The minimum pulling force of the device 72 must be through an adjustable sleeve screw 78 to generate different cable distances to obtain the lowest torque value, and the motor can be electrically connected to an external electronic control to control the motor. . The known resistance wheel train is that the motor is passed through the wire rope 74 to control the magnet on the stone to be mounted on the pedestal of the flywheel 76, and the motor is placed on the resistance seat.

In addition, because the 1323005 has and the sleeve screw 78 can only be adjusted at a single point (ie, zero adjustment), the tension is adjusted through the cable 74 (very accurate is almost impossible. The fly is adjusted to the phase of 5; The correct pull value, you must also pull the tension and angle - and ^ write the electronic control board in the record dragon, only to complete the setting. And the electronic control board is actually separated from the entire resistance wheel and only through the 'and therefore electronic control If the plate, the wire puller, the sleeve screw or the cable is damaged and replaced, then the torque setting is not correct, so the control of the tension may also be inaccurate.

Thereby, the memory body can be preset in the memory The magnet group acts on the resistance parameter of the flywheel to achieve a predetermined effect. [Embodiment] In order to explain in detail the structure and characteristics of the present invention, the following 10 - The preferred embodiment and the following description of the drawings, wherein: as shown in the first to third figures, the first preferred embodiment of the present invention provides a fitness wheel set 10 with preset resistance parameters, The utility model is mainly composed of a base 11, a flywheel 21, a damper 31, a motor 41 and a control circuit 51, wherein: the base 11 extends upwardly from a pole 12, and a fixed disk 14 is attached to the frame. The flywheel 21 is disposed on the frame 12 of the base 11, and in the embodiment, the flywheel 21 is concentric with the center of the fixed disk 14. The damper 31 is disposed on the fixed disk 14, The damper 31 has a 2-inch displacement mechanism 32 and a magnet group 36 disposed on the displacement mechanism 32. The magnet group 36 is composed of two arc-shaped magnetic plates 37, one end of which can be The arc-shaped outer edge of the two arc-shaped magnetic plates 37 corresponds to the circumference of the fixed disk 14. The displacement mechanism 32 has a knob 33 and a two-link 34. The knob 33 has an elongated body 1323668 331 passing through the fixing plate 14, and a connecting block 332 is formed at the end of the elongated body 331. A connecting arm extends to the two sides, and the connecting rods 34 are respectively swingably connected at one end thereof to the end of the connecting arm 3, and the two connecting rods 34 are respectively swingably connected at their other ends. The free end of the two arc 5-shaped magnetic plate 37. By driving the knob 33, the two links 34 can be driven to drive the two arc-shaped magnetic plates 37 toward/away from the flywheel 21. The motor 41 is disposed on the fixed disk 14 and is coupled to a gear box 44. The gear box 44 is coupled to the connecting block 332 of the displacement mechanism 32. Thereby, the gear box 44 can be driven by the motor 41, and the knob 33 can be driven to oscillate the two arc-shaped magnetic plates 37, and the position of the two arc-shaped magnetic plates 37 can be adjusted. The control circuit 51 mainly has a processor 52, and has an angle sensor 53 connected to the processor 52 and a memory. The control circuit 51 is connected to the motor 41 and the damper 3 The position of the magnet group 36 is detected and the motor 41 is controlled to drive the displacement mechanism to adjust the position of the magnet group 36.
