Device for supplying air source for air controlled gear changing system

Abstract

The invention discloses a device for providing air sources for an air control shift system, wherein, a by-pass line at the front part of an exhaust pipe is connected with an intake pipe by a three-way catalyst; the intake pipe is connected with an air inlet of a one-way valve; an air outlet of the one-way valve is arranged at an inlet of the an air tank; an outlet of the air tank is connected with an air inlet of a valve housing by an air pipe; the valve housing is sheathed on a valve core; an inner end of the valve core is fixed with a shift rod of an engine; the air inlet of the valve housing is selectively communicated with a first air outlet or a second air outlet by a commutating channel of the valve core; the first air outlet and the second air outlet are respectively communicated with a rod cavity and a rodless cavity of an executive cylinder; a piston rod of the executive cylinder is articulated with the lower end of a driving arm; the upper end of the driving arm is fixed with the outer end of the valve core; a control dial is movably sheathed on the valve core; the control dial is connected with a roller wheel by a stay rope; the roller wheel is arranged on a control handle. By controlling the engine to shift the gear under air control, the device of the invention not only has the advantages of simple operation, accuracy and reliability, but also effectively prevents the occurrence of the trip stop and improves the safety of driving.

Description

technical field [0001] The invention relates to a device for providing an air source for an air-controlled shifting system, so as to absorb and store the gas discharged from an exhaust pipe, and to change gears through pneumatically controlling the engine. Background technique [0002] At present, natural air-cooled engines are generally installed on riding motorcycles, and stepped transmissions are adopted. Stepped transmissions have high transmission efficiency and low energy consumption, but the control of gear shifting is complex and has poor accuracy. This is because the shifting operation of the riding motorcycle is carried out by the driver controlling the movement of the engine shift lever with his feet. The gear of the engine is a cycle gear, and there are only two dynamic positions of the engine shift lever. When the driver steps on the shift pedal with his left foot to make the engine shift lever rotate clockwise or counterclockwise with the shift pedal, the engi...

Problems solved by technology

However, the transmission efficiency of the belt continuously variable transmission is low, only about 75%, and the energy consumption and the heat generated by the engine are large, and the air cooling effect is not ideal

If the scooter uses a natural air-cooled engine and a stepped transmission, it is extremely inconvenient to use the pedal to control the gear change because the user uses a sitting style of driving.

[0004] On the other hand, the exhaust pipe is a part of the exhaust muffler of the motorcycle. The front end of the exhaust pipe is connected to the exhaust port of the engine. When the motorcycle engine is working normally, it will generate 0.2-0.5Mpa near the exhaust port. The air pressure is then discharged into the atmosphere through the exhaust pipe and muffler. The energy contained in the high-pressure gas in the exhaust pipe is lost in vain and cannot be effectively utilized.
