摘要:
An apparatus provides variable resistance to rotation and includes a housing having a shaft having a first portion that is rotatable in the housing and a second portion passing outwardly thereof adapted to receive the tire of a bicycle for stationary bicycle exercise. A first body in the housing is mechanically linked to the first portion of the shaft so as to be rotatable within the housing. A second body in the housing is slidably connected to the first portion of the shaft and has flat face opposed to the flat face of the first body. The second body is movable with respect to the first body to result in a variably-sized gap between the opposed faces. A spring located between the housing and the second body biases the second body toward the first body. Further mechanism is provided to permit adjustment of the gap between the first body and the second body, and a viscous fluid in the housing frictionally engages the bodies and provides resistance to their rotation, with the amount of resistance dependent upon the size of the gap.
