Abstract

The invention discloses a pneumatic motor power system for a power-aided bicycle. The pneumatic motor power system includes a pneumatic motor unit. The pneumatic motor unit includes a crankshaft chamber and a shaft hole which are communicated with each other, a bushing is nested in the shaft hole, a motor spindle coaxially rotatably passes through the bushing, and a plurality of air holes are distributed in the sleeve wall of the bushing. The shaft wall of the motor spindle is provided with a first air distribution groove and a second air distribution groove, and the first air distribution groove and the second air distribution groove respectively sequentially rotate with the motor spindle to be communicated with each air hole. By the adoption of a pneumatic motor in the scheme for strongpower for the bicycle, an instant torque is larger, the situation that a motor is short-circuited easily after a conventional electric bicycle suddenly stops is avoided, and the safety is higher; a three-cylinder type driving piston is adopted, and the power system transmission is more stable; compared with a lithium battery as output power, pneumatic motor is greener clean power and is more environmentally friendly, and the environmental pollution problem that it is difficult to treat and degrade a large number of abandoned lithium batteries can be solved effectively.

Description

technical field [0001] The invention belongs to the field of power-assisted bicycles, and in particular relates to an air motor power system and a method thereof for power-assisted bicycles. Background technique [0002] With the update and iteration of science and technology, and the characteristics of my country's densely populated society, the power-assisted mode of bicycles, one of the important means of transportation that is convenient for residents' daily travel, has gradually transitioned from manpower to electric power. The power-assisted bicycles on the existing market mainly rely on storage The electric lithium battery is used as the output power to realize the boost and advance of the bicycle. Compared with the previous small-displacement oil-burning engines, the application of lithium batteries has avoided exhaust emissions that are seriously harmful to the human body, and has made great progress in environmental protection. However, with the production, applicat...
