The interlocking cable 43 has a caught end 431 directly connected to the catch 213 of the swing arm 21 and a connecting end 432 opposite to the caught end 431. The damping wheel 42 is axially arranged on The front plate 123 also has a gear 421 . The interlocking cable 43 in this embodiment is wound around the roller 124 and the damping wheel 42 , and also has a single rack 433 engaged with the gear 421 . The damping generating part 44 is formed by the opposite end of the caught end 431. In this embodiment, the damping generating part 44 is respectively connected to the connecting end 432, and can provide the swing The arm 21 corresponds to the damping of a horizontal vector X, and has a constant potential energy to make the locked end 431 return to the opposite direction after being locked. In this embodiment, the damping generating part 44 is a tension spring, and can also be an elastic strip or a hydraulic cylinder (not shown in the figure).

The vertical damping unit 50 can provide damping corresponding to a vertical vector Y of the rear end portion 312 of the pedal rod 31 of the pedal unit 30 . The vertical damping unit 50 has a brake wheel 51 mounted on the base 11, a pair of drive wheels 52 with shafts on the base 11 and one side of the brake wheel 51, a drive wheel 52 connected to the brake wheel 51 and one of the drive wheels. A transmission member 53 of 52 and an eccentric crankshaft 54 whose axis is arranged between the driving wheels 52 . The brake wheel 51 provides damping of the rear end portion 312 of the pedal rod 31 corresponding to the vertical vector Y. The frame 10 also has a guide member 14 connected to the base 11 through the crank shaft 54 , and the guide member 14 in this embodiment is two bearings respectively disposed on opposite ends of the crank shaft 54 . The rear end 312 of the step bar 31 can straddle the two bearings of the guide 14 and slide relative to the guide 14 .

Utilizing the elliptical machine composed of the above-mentioned components, when the operator intends to perform the slide operation mode, the crank shaft 54 of the vertical damping unit 50 is hardly driven, and when both feet step on the pedal 32, and use both feet When the pedal 32 and the pedal rod 31 are applied horizontally and forwardly, the front end 311 of the pedal rod 31 will push the swing portion 212 of the swing arm 21, and the swing arm 21 will be pivoted. The part 211 is the center of rotation to generate swing, and the setting of the linkage unit 70 can make the pedal 31 , the swing arm 21 and the handle 61 produce coordinated linkage.

While the swing arm 21 is swinging, the stopper 213 is used to actuate the locked end 431 of the interlocking cable 43 of the horizontal damping unit 40 , and the interlocking cable 43 passes around the roller. 124 can be braked smoothly, and the interlocking cable 43 can smoothly drive the damping wheel 42 to rotate through the meshing of the single rack 433 and the gear 421 to generate a part of the horizontal vector X damping. And when the swing arm 21 swings forward, the damping generating part 44 is pulled and generates another part of the damping of the horizontal vector X (at this time, the damping generating part 44 is stretched to store return elastic force), therefore, using the damping sum of the horizontal vector X, the operator can achieve the training purpose of the legs, and when the operator's force is eliminated, the return elastic force of the damping generating part 44 will make The potential energy of the locked end portion 431 is reversed after being locked, that is to say, the swing arm 21 has the ability to swing back. Thereby, the sense of rhythm of the operator's operation can be increased.

When the operator intends to perform the operation mode of stepping and elliptical motion track, use both feet to apply force to the pedal 32 and the pedal bar 31 in the horizontal direction and forward, and to apply force in the vertical direction and downward, and the pedal bar 31 The front end 311 of 31 will push the swing part 212 of the swing arm 21, and the swing arm 21 will swing with the pivot joint 211 as the center of rotation, and the linkage cable 43 of the horizontal damping unit 40 and the damping The generating part 44 is activated to generate damping of the horizontal vector X. Simultaneously, the damping of the vertical vector Y can be produced by using the pedal rod 31 to alternately exert downward braking action on both ends of the crankshaft 54 and by using the arrangement of the vertical damping unit 50 .

In addition to the above two operation modes, when the operator intends to simply step up and down the operation mode, use both feet to apply force vertically and downward to the pedal 32 and the pedal bar 31, and the pedal 32 and the pedal bar 31 The two ends of the crankshaft 54 are alternately forced downward, and the damping of the vertical vector Y can be generated by the arrangement of the vertical damping unit 50 . At this time, the swing arm 21 hardly swings, and the horizontal damping unit 40 hardly produces the damping of the horizontal vector X.

Therefore, using different operation modes of the operator can produce different damping, and the operator can choose different operation modes according to the needs, such as: the operation mode of stepping up and down and the elliptical motion track of front and back, the sliding operation mode, or simply stepping up and down operating mode.

The horizontal damping unit 40 of the present invention uses the swing arm 21 to directly link the interlocking cable 43, and utilizes the meshing of the single-sided rack 433 of the interlocking cable 43 with the gear 421 to drive the The damping wheel 42 rotates to generate the damping of the horizontal vector X. In addition, the damping generating part 44 is pulled to generate another part of the damping of the horizontal vector X, so the expected damping effect can be produced, and because there is no Frictional damping, so the generation of fines and dust can be reduced. When the force applied by the operator is eliminated, the elastic force of the damping generating part 44 will make the restrained end 431 return to the reverse direction after being restrained. , can achieve the purpose of smooth operation.
