Manual variable-speed driving device, man-powered bicycle, man-powered aircraft and man-powered ship

Abstract

The invention provides a manual variable-speed driving device which comprises a rack, a force application handle, a main power shaft, a one-way overrunning clutch, a reset device and a variable-speed gear set. One end of the force application handle is connected with the input end of the one-way overrunning clutch, and the output end of the one-way overrunning clutch is connected to the main power shaft; the force application handle rotates around the main power shaft in a reciprocating mode to sweep a sector face to move and do work, a driving force arm corresponding to the force application handle directly drives the input end of the one-way overrunning clutch to rotate forwards and backwards, so that the output end of the one-way overrunning clutch is intermittently driven to rotate in a one-way mode. The variable-speed gear set is an angular speed increasing gear set and comprises an input end gear, a middle change gear set and a terminal gear; the output end of the one-way overrunning clutch is fixedly connected with the input end gear through a main power shaft. The invention further provides a man-powered bicycle, a man-powered aircraft and a man-powered ship. The power output efficiency is high, the structure is compact, the arm of force is long, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of transportation tools, in particular to a human-powered variable-speed driving device, a human-powered bicycle, a human-powered aircraft and a human-powered boat. Background technique [0002] Human-powered transportation tools include human-powered pedal aircraft, human-powered pedal boats, and pedal bicycles, among which pedal bicycles are the most common human-powered transportation equipment. Pedal bicycles are generally small land vehicles such as two wheels or three wheels. [0003] The power conversion transmission mechanism of a traditional pedal bicycle includes a center shaft assembly, a crank assembly, a rear wheel shaft assembly, and a driving chain plate, a chain, and a driven sprocket assembly; its power comes from the continuous circular motion of human legs, Drive the left and right cranks and the driving chain plate to rotate continuously 360°, and the power is transmitted from the driving chain pl...

Problems solved by technology

Although the length of the force arm of this reciprocating mechanism is not limited by the distance between the rotation axis and the ground, but by the telescopic distance of the legs, its actual force arm is the length of the driving force arm minus the resistance arm. The shorter the moment arm, the harder it is

[0006] In addition, the arc-shaped rack is fixed on the upper part of the long force arm of the shifting component of the hand-pinch generator flashlight. The rack drives the shifting gear reciprocatingly and then drives the ratchet to drive the generator to rotate. There is no problem with such a shifting drive with small scale and low power. Once the scale is enlarged, When the power requirement is high, the rack and pinion drive is heavy, and the contradiction between the open structure and the meshing accuracy requirements is reflected. Therefore, such a structure is not suitable for the use of light, human-powered vehicles with complicated working conditions. For example, the application number: KR1020080045340 beyond The system is used for four-wheel bicycles, which is such a structure. In fact, it has not been promoted, which is caused by such structural defects.
