Claim:
1. A damping device for working with exercise equipment that stands on the ground with a frame unit, the damping device comprising: a transmission unit, being installed at one end of the frame unit and including a driven shaft, a driving wheel mounted around a middle section of the driven shaft, a first rotating wheel pivotally connected to one end of the driven shaft, a second rotating wheel pivotally connected to an opposite end of the driven shaft, a woven ribbon having one end thereof fixed to the driving wheel and being wound around the driving wheel, a first driving belt, and a second driving belt, wherein the first rotating wheel and the second rotating wheel are located at two reverse sides of the driving wheel, respectively; a tension unit, having a handle bar, in which the woven ribbon of the transmission unit has its opposite end connected to a middle section of the handle bar, so that when receiving a push/pull force, the handle bar drives the driving wheel and the driven shaft to rotate, and in turn drives the first rotating wheel and the second rotating wheel to rotate through the driven shaft; and a resistance unit, including a resistance fan provided at the end of the frame unit and located outside and below the first rotating wheel, and an adjustable resistance member provided at the end of the frame unit and located outside and below the second rotating wheel, the resistance fan having a fan wheel and an axle passing through the fan wheel and connected to the frame unit, the adjustable resistance member having a resistance generator connected to the frame unit and a main shaft projecting from the resistance generator, the first driving belt of the transmission unit being connected between the first rotating wheel and the axle of the resistance fan, and the second driving belt of the transmission unit being connected between the second rotating wheel and the main shaft of the adjustable resistance member, whereby when rotating, the first rotating wheel and the second rotating wheel drive the axle and the main shaft to rotate, respectively, by means of the first driving belt and the second driving belt, thereby driving the fan wheel to rotate and making the resistance generator of the adjustable resistance member output resistance.
