Muscle-powered vehicle e.g. bicycle, has gear rod mounted such that gear rod is coupled with gear wheel, where gear rod is rigidly connected with pistons of hydraulic cylinder of drive device

摘要

The vehicle has pistons respectively coupled with cylinder spaces of a hydraulic cylinder of a drive device (5), where the cylinder spaces are respectively connected with piston areas of other hydraulic cylinders (15-1, 15-2) by hoses (18-1, 18-2). A gear wheel is coupled with a shaft (24) of a rear drive wheel (4) by a free-wheel clutch. A gear rod is mounted such that the gear rod is coupled with the gear wheel. The gear rod is rigidly connected with the pistons of the former hydraulic cylinder.
