Shifting fork type non-motor vehicle

Abstract

The invention discloses a shifting fork type non-motor vehicle, which is characterized in that: a vehicle body under a seat is provided with a reciprocating gearbox; the inside of the reciprocating gearbox is provided with a reciprocating gear assembly; the seat is connected with a guide rail shaft; the guide rail shaft is fixed with a spring prop; a spring is arranged between the spring prop andthe reciprocating gearbox; the spring prop is connected with a rear shifting fork; the rear shifting fork is connected with a rear shifting fork arm; the rear shifting fork arm is rotatably connectedwith the vehicle body; the lower end of the guide rail shaft is connected with an auxiliary chain wheel through the reciprocating gear assembly; the auxiliary chain wheel is connected with an auxiliary flywheel through an auxiliary chain; and the auxiliary flywheel is connected with a driving wheel. The vehicle uses the guide rail shaft to drive the reciprocating gear assembly to move through theup-and-down movement of the seat so as to drive the driving wheel to rotate through the auxiliary chain wheel and the auxiliary flywheel. The vehicle can assist in driving vehicle wheels to rotate through the up-and-down movement of the seat, thereby ensuring that the shifting fork type non-motor vehicle is quicker and easier to ride.

Description

Technical field [0001] The invention relates to the field of non-motor vehicles, in particular to a fork-type non-motor vehicle that uses a movable seat stool for auxiliary driving. Background technique [0002] As a convenient means of transportation, bicycles have been closely connected with people’s daily life. With people’s demand for bicycles, the requirements for bicycles are also getting higher and higher. Since 1816, the first wooden fixed seat stool appeared in France. Bicycles, excerpted from "Mechanical Innovation Design", have been developed to date, nearly 200 years of history, bicycles have been greatly improved and updated. For example: a single-power single-speed bicycle with a pedal has developed into a single-power pedal with two large and small diameter double sprockets. Through the front and rear chain shifters, the chain can engage multiple single flywheels of different diameters for rotation. Perform multi-speed conversion to drive the wheels forward. Howe...

Problems solved by technology

But no matter how the speed of the vehicle changes, the traditional fixed seat bench bicycle is all single power, relying on the pedals for driving, if the foot does not step on the bicycle, it cannot move forward, and this multi-speed fixed seat bench bicycle, due to the increase of the chain wheel and the flywheel The front and rear shifters, especially the rear chain, rotate along the "S" curve of the rear shifter, so the frictional resistance increases, and it takes a little effort to pedal
