As shown in FIG. 5, according to a preferred embodiment of the present invention, the radius of the driving wheel 222 may be greater than the radius of the driven wheel 225, and the radius of the driving wheel 224 may be greater than the passive wheel 223. Moreover, the radius of the driving wheel 222 may be greater than the radius of the driving wheel 224, and the radius of the driving wheel 224 may be greater than the radius of the driven wheel 225. Of course, the relationship between the driving wheel and the radius of the passive wheel can also take other relationships as needed.

The two unidirectional runners 211 are provided with grooves in different directions, gp, and the grooves on one unidirectional runner are on the outer peripheral surface of the one-way runner, starting from the side away from the accommodating chamber, clockwise A spiral groove that rotates in the direction. The groove on the other one-way wheel is a spiral groove which is rotated in the counterclockwise direction from the side away from the accommodating chamber on the outer peripheral surface of the unidirectional wheel.

The two unidirectional runners 21 1 alternately drive the drive shaft 21, so that the two unidirectional runners 211 can drive the drive shaft 21 to rotate in the same direction, so that the drive shaft 21 drives the drive wheel 222 to rotate, and the drive wheel 222 drives through the belt 226. The driven wheel 223 rotates to drive the driven shaft 221 to rotate. The driven shaft 221 drives the driving wheel 224 to rotate. The driving wheel 224 rotates the driven wheel 223 through the belt. The driven wheel 223 drives the large disc 228 pivotally mounted on the driving shaft 21 to rotate. Thus, the large disc 228 is ultimately driven to rotate by means of the transmission assembly 22. Of course, the specific construction of the transmission assembly is not limited to the previously described construction, and any other type of transmission assembly can be used to drive the large disc 228. The large disc 228 can be made of a material that is affected by a magnetic field, such as a metal or magnetic material.

For example, the one-way runner 211 may adopt a structure in which a wheel hole is provided in the one-way runner 211 and a one-way bearing is installed in the wheel bore for the drive shaft 21 to penetrate therein, and the one-way runner is provided. 21 1 It is mounted on the drive shaft 21 (shown in the figure is installed and integrated). It is of course also possible to mount the one-way runner 21 1 on the drive shaft 21 by various known methods.

The pedaling assembly 3 includes two stepping levers 31, and the two pedaling levers 31 are pivotally coupled to the two sides below the frame body 1 respectively; and the length of the pedaling lever 31 is adjustable as shown in FIG.

The traction belt 5 is strip-shaped, and its central portion is wound on the outer side of the idler pulley 4, and a part of both sides of the central portion of the traction belt is wound around the grooves on the two one-way runners 211, respectively. On the two unidirectional runners 211, the two ends of the traction belt 5 are respectively connected to the side edges of the two aforementioned stepping levers 31.

The magnetoresistive device 6 is provided with a knob 61 and a magnetoresistive member 62, and the knob 61 and the magnetoresistive member 62 are connected by a pull cord 63, and the magnetoresistive member 62 can generate a magnetic resistance to the large disc 228, thereby driving the transmission. The assembly creates resistance and thus creates resistance to the transmission. By rotating the aforementioned knob 61, the position of the magnetoresistive member 62 can be changed, thereby changing the magnitude of the magnetic resistance of the magnetoresistive member 62 to the large disk 228, and the magnetoresistive member 62 is provided with a C-shaped opening 621 and having a plurality of magnets therein. The outer circumference of the large disc 228 can be inserted into the C-shaped opening 621.

The counting device Ί includes a sensor 71 and is mounted on the frame 1 adjacent to the step 31 to detect the number of times the step 71 is stepped on.

Referring to FIGS. 3 and 4, the pedaling principle of the pedaling machine of the present invention is such that the central portion of the traction belt 5 is sleeved on the idler pulley 4, and a part of both sides of the central portion of the traction belt 5 is respectively wound around the drive shaft. In the groove of the one-way runner 211 on both ends of the 21, the two ends of the traction belt 5 are respectively connected to the inner sides of the two stepping rods 31, and are repeatedly stepped on by the user on the pedal lever 31 alternately (see FIG. The drive shaft 21 is driven to rotate by the traction belt 5, and then the driving wheel 222 on the driving shaft 21 drives the driven wheel 223 on the driven shaft 221 to rotate via the belt 226, while the driven wheel 223 drives the driven shaft 221 to rotate. The wheel 221 drives the driving wheel 224 on the driven wheel 221 to rotate. Then, the driving wheel 224 drives the driven wheel 225 on the driving shaft 21 to rotate through the belt 227. Finally, the driven wheel 225 rotates the large disk 228 to rotate. The outer circumference of the 228 may pass through the C-shaped opening 621 of the magnetoresistive member 62, and the plurality of magnets therein may have a magnetoresistance effect on the large disc 228, thereby forming resistance to the user's pedaling, thereby achieving the motion effect.

Referring to FIG. 5, the magnetic resistance of the magnetoresistive device 6 is adjusted by rotating the knob 61 provided on the frame body 1 to pull the pull cord 63, thereby pulling the magnetoresistive member 62, and changing the magnetoresistive member 62. The relative position with the large disk 228, the deeper the outer circumference of the large disk 228 enters the C-shaped opening 621 of the magnetoresistive member 62, the greater the resulting magnetic resistance, if the outer periphery of the large disk 228 enters the magnetoresistive member. If the depth of the C-shaped opening 621 of 62 is shallow, the resulting magnetic resistance will be small.

It should be noted that the above is a technical principle applied by a specific embodiment of the present invention. If the concept of the present invention is changed, the functional function produced by the present invention does not exceed the ideas covered by the specification and the drawings. All of them should fall within the scope of the present invention and are described together here.
