Embodiment

[0019] Example: see figure 1 and figure 2 , a new type of bicycle, the middle part of the swing pedal 1 is movably connected to the fixed rod 2, the ejector rod 4 of the first oil cylinder 3 is movably connected to the swing pedal 1, the cylinder bottom 5 of the first oil cylinder 3 is movably connected to the fixed rod 2, the first The position of the second oil cylinder 6 is fixed on the bicycle body. The ejector rod 7 of the second oil cylinder 6 is fixedly connected to the drive gear 8. The gear surface of the drive gear 8 can be meshed with the gear surface of the flywheel 9. The oil inlet and outlet 10 of the first oil cylinder bottom 5 The oil inlet and outlet 12 of the second oil cylinder bottom 11 are communicated through the hydraulic oil pipe 15 , and the oil inlet and outlet 14 of the first oil cylinder cylinder top 13 are communicated with the oil inlet and outlet 17 of the second oil cylinder cylinder top 16 through the hydraulic oil pipe 15 .

Abstract

The invention discloses a new type of bicycle for usual life. The central part of its pendulum pedal is jointed with the fixed rod; the crown bar of the first oil tank movably connects the pendulum pedal and the bottom of the tank movably connects the fixed rod; the second tank is fixed at the bicycle body, and the crown bar of the second oil tank is fixed with the driving gear, and the face of the driving fear toe joints the face of the flywheel; the inlet and outlet at the bottom of the first tank connect the inlet and outlet of the second oil tank through the hydraulic oil pipe, and the inlet and the outlet at the top of the first tank connect the inlet and the outlet at the top of the second tank through the hydraulic oil pipe. The invention has high driving efficiency.

Description

technical field [0001] The invention relates to a bicycle, in particular to a hydraulically driven bicycle. Background technique [0002] Most of the current conventional bicycles are chain transmissions, but this chain type bicycle has more losses due to the larger friction between its chain and the sprocket wheel, which reduces the driving efficiency. There are also a small number of shaft-driven bicycles, which have the disadvantages that the frictional force between transmission mechanisms is relatively large and the drive efficiency is low. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a new type of bicycle, which has higher driving efficiency, and long-distance riding is not easy to make people tired. [0004] The technical scheme adopted by the present invention in order to solve its technical problems is: the middle part of the swing pedal is movably connected to the fixed rod, the ejector rod o...
