The first driving wheel 301 is connected to a third driving wheel 303 via a first transmission 305, and the second driving wheel 302 is connected to a fourth driving wheel 304 via a second transmission 306. As shown in fig. 3A, the diameter of the third transmission wheel 303 is smaller than the diameter of the first flywheel 310, the third transmission wheel 303 may have a portion 3031 extending axially to the center of the first flywheel 310, and a first one-way bearing 3101 is provided between the outer circumference of the portion 3031 and the first flywheel 310; as shown in fig. 3B, the diameter of the fourth transmission wheel 304 is smaller than that of the second flywheel 311, and the fourth transmission wheel 304 may have a portion 3041 extending axially to the center of the second flywheel 311, and a second one-way bearing 3111 between the outer periphery of the portion 3041 and the second flywheel 311. With the above structure, only one of the first flywheel 310 and the second flywheel 311 rotates at the same time, and the rotation directions of the two flywheels are opposite.

As shown in fig. 3A to 3C, preferably, the first transmission wheel 301, the second transmission wheel 302, the third transmission wheel 303, and the fourth transmission wheel 304 are belt pulleys; the first transmission member 305 and the second transmission member 306 are belts.

As shown in fig. 3A to 3C, in the present embodiment, the resistance device 30 further includes a first pressure roller 308 and a second pressure roller 309. The first pressing wheel 308 is disposed on one side of the first flywheel 310 for adjusting the tension of the first transmission member 305.

Preferably, first pressure wheel 308 and second pressure wheel 309 are pulleys.

Fig. 4 and 5 are schematic diagrams illustrating the operation of the resistance device 30 of the exercise apparatus 1 in the "small stepping stroke" state according to an embodiment of the present invention. As used herein, the "large step stroke" refers to the reciprocating movement of the pedal 206 operated at the highest position and the lowest position, and the "small step stroke" refers to the reciprocating movement of the pedal 206 operated at a distance shorter than the "large step stroke".

As shown in fig. 4, when the user operates the pedal 206, the kinetic energy is transmitted from the crank 203 to the first axle 300 and drives the first transmission wheel 301 and the second transmission wheel 302 to rotate in a first direction (e.g., clockwise). The first driving wheel 301 and the second driving wheel 302 respectively drive the third driving wheel 303 and the fourth driving wheel 304 to rotate in a first direction through the first driving member 305 and the second driving member 306. At this time, the second one-way bearing 3111 (fig. 3B) in the second flywheel 311 is disengaged from the fourth transmission wheel 304, the first one-way bearing 3101 in the first flywheel 310 is engaged with the third transmission wheel 303, and the driving kinetic energy is transmitted to the third transmission wheel 303 through the first transmission piece 305 and then transmitted to the first flywheel 310, so that the first flywheel 310 rotates in a first direction (e.g. clockwise), and the second flywheel 311 is stationary.

As shown in fig. 5, when the user operates the pedal 206, the kinetic energy is transmitted from the crank 203 to the first axle 300 and drives the first transmission wheel 301 and the second transmission wheel 302 to rotate in a second direction (e.g., counterclockwise). The first driving wheel 301 and the second driving wheel 302 respectively drive the third driving wheel 303 and the fourth driving wheel 304 to rotate in the second direction through the first driving member 305 and the second driving member 306. At this time, the second one-way bearing 3111 in the second flywheel 311 is engaged with the fourth transmission wheel 304, the first one-way bearing 3101 in the first flywheel 310 is disengaged from the third transmission wheel 303, and the driving kinetic energy is transmitted to the fourth transmission wheel 304 through the second transmission member 306 and then transmitted to the second flywheel 311, so that the second flywheel 311 rotates in the second direction (e.g., counterclockwise), and the first flywheel 310 is stationary.

Therefore, as shown in fig. 4-5, when the resistance device 30 is operated in the "small stepping stroke", the reciprocating motion of the two pedals 206 causes the first flywheel 310 and the second flywheel 311 to rotate alternately.

In addition, the exercise apparatus 1 of the embodiment of the present invention operates in the "striding stroke" similar to that shown in fig. 4 or 5, and the resistance device 30 can provide resistance to the pedal 206 regardless of the direction of operation. As shown in fig. 4, when the user steps on the two pedals 206 to reciprocate at the maximum stroke, the first driving wheel 301 and the second driving wheel 302 rotate in the first direction, and the kinetic energy is transmitted to the third driving wheel 303 and the fourth driving wheel 304 through the first transmission piece 305 and the second transmission piece 306, respectively, so that the first flywheel 310 continuously rotates in the first direction due to the engagement of the first one-way bearing 3101 with the third driving wheel 303 and the inertia effect of the first flywheel 310, and the second flywheel 311 remains stationary. Alternatively, as shown in fig. 5, the user steps on the two pedals 206 to reciprocate at their maximum stroke, causing the first transmission wheel 301 and the second transmission wheel 302 to rotate in the second direction, and transmitting the kinetic energy to the third transmission wheel 303 and the fourth transmission wheel 304 through the first transmission piece 305 and the second transmission piece 306, and due to the engagement of the second one-way bearing 3111 and the fourth transmission wheel 304 and the inertia of the second flywheel 311, causing the second flywheel 311 to continuously rotate in the second direction, while the first flywheel 310 remains stationary. Thus, the resistance device 30 provides resistance to the pedal 206 regardless of the direction of operation.

According to the exercise apparatus 1 provided in the preferred embodiment, when operating in the "small stepping stroke", the first transmission wheel 301 and the second transmission wheel 302 rotate alternately in the first direction and the second direction, causing the first flywheel 310 and the second flywheel 311 to rotate alternately, so that there is no feeling of retardation when switching directions and smooth operation is possible. In addition, when the pedal 206 is operated in the "striding stroke", one of the first flywheel 310 and the second flywheel 311 can provide resistance to the pedal 206 in any direction.
