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. In this context, "step stroke" refers to the reciprocating movement of the pedal 26 operated at its uppermost position and its lowermost position, and "step stroke" refers to the reciprocating movement of the pedal 26 operated at a distance shorter than the "step stroke".

As shown in fig. 4, when the user operates the pedal 26, the kinetic energy is transmitted from the crank 23 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 drives the fourth driving wheel 304 to rotate in a first direction, and the second driving wheel 302 drives the fifth driving wheel 305 to rotate in a second direction (e.g., counterclockwise). At this time, the second one-way bearing 3051 in the fifth driving wheel 305 is disengaged from the second hub 310, the first one-way bearing 3041 in the fourth driving wheel 304 is engaged with the second hub 310, the driving kinetic energy is transmitted from the fourth driving wheel 304 to the second hub 310, so as to cause the rotation of the third driving wheel 303, and the third driving wheel 303 transmits the kinetic energy to the flywheel 306, so as to cause the rotation of the flywheel 306.

The first driving wheel 301 drives the fourth driving wheel 304 to rotate in the second direction, and the second driving wheel 302 drives the fifth driving wheel 305 to rotate in the first direction (e.g. clockwise). At this time, the second one-way bearing 3051 of the fifth pulley 305 is engaged with the second axis 310, the first one-way bearing 3041 of the fourth pulley 304 is disengaged from the second axis 310, the driving kinetic energy is transmitted from the fifth pulley 305 to the second axis 310, causing the third pulley 303 to rotate, and the third pulley 303 transmits the kinetic energy to the flywheel 306, causing the flywheel 306 to rotate. In the present embodiment, the flywheel 306 also rotates in a second direction (e.g., counterclockwise). In another embodiment, flywheel 306 rotates in a first direction (e.g., clockwise) by a different configuration of third transmission 309.

In addition, the operation of the resistance device 30 of the exercise apparatus 1 provided by the embodiment of the present invention is similar to that of fig. 4 due to the inertia of the flywheel 306 during the "striding stroke". The kinetic energy is transmitted from the crank 23 to the first axle 300 and drives the first driving wheel 301 and the second driving wheel 302 to rotate in a first direction (e.g. clockwise). The first driving wheel 301 drives the fourth driving wheel 304 to rotate in a first direction, and the second driving wheel 302 drives the fifth driving wheel 305 to rotate in a second direction (e.g., counterclockwise). At this time, the second one-way bearing 3051 in the fifth driving wheel 305 is disengaged from the second hub 310, the first one-way bearing 3041 in the fourth driving wheel 304 is engaged with the second hub 310, the driving kinetic energy is transmitted from the fourth driving wheel 304 to the second hub 310, so as to cause the rotation of the third driving wheel 303, and the third driving wheel 303 transmits the kinetic energy to the flywheel 306, so as to cause the rotation of the flywheel 306.

According to the exercise apparatus 1 of the preferred embodiment, when operating in the "small stepping stroke", the kinetic energy can be transmitted to the third transmission wheel 303 in real time regardless of whether the first transmission wheel 301 and the second transmission wheel 302 rotate in the first direction or the second direction, so that the flywheel 306 continuously rotates in a single direction, and the operation can be performed smoothly without any feeling of retardation when changing the direction.
