The following technical scheme of employing of the present utility model:
A kind of FSAE racing car shifting system, comprise the gas cylinder that pressed gas is provided, reducing valve, clutch electromagnetic valve, clutch air cylinder, shifting cylinder, gearshift electromagnetic valve and micro controller system, described gas cylinder connects reducing valve by pipeline, through post-decompression pressed gas by pipeline connect respectively clutch electromagnetic valve and gearshift electromagnetic valve to connection, described clutch electromagnetic valve is connected with the clutch air cylinder of control clutch by pipeline, described gearshift electromagnetic valve is connected with the shifting cylinder of controlling gearshift by pipeline, described clutch electromagnetic valve and gearshift electromagnetic valve are all connected with single chip circuit, and be connected with single chip circuit for controlling clutch button and the gearshift button of clutch electromagnetic valve and gearshift electromagnetic valve.
Further, described gearshift electromagnetic valve is 3 position-5 way electromagnetic valve, and described clutch electromagnetic valve is two-bit triplet electromagnetic valve.
Further, described pressed gas is carbon dioxide.
Further, also comprise for the hand clutch mechanism in the submissive combination of racing car starting current events power-transfer clutch.
During upshift, upshift switch connection, the break-off of ECU control engine ignition system, gearshift electromagnetic valve is connected after moving to the position that upgrades, and drive of high-pressure gas shifting cylinder is realized upshift action.During downshift, kickdown switch is connected, and clutch electromagnetic valve is connected, drive of high-pressure gas clutch air cylinder, disengaging of clutch.After the corresponding time of clutch air cylinder work, gearshift electromagnetic valve moves to work behind the position that lowers category, and drive of high-pressure gas shifting cylinder is realized downshift action.Pneumatic circuit source of the gas is high-pressure carbon dioxide gas, and the required low-pressure gas in loop is to be reduced pressure and obtained by reducing valve; Circuit part is to design according to the control function of micro controller system, finally produces pcb board; Because cylinder is swift in motion, the submissive combination problem of power-transfer clutch while starting to walk for solving, has designed separately hand clutch mechanism ，Gai mechanism and only in starting and parking, has worked, and its lifting gear is to control by cylinder.
The utility model proposes a set of semi-automatic shift gears system and replaced traditional manual shift system.Consider the programming problem of electronic control unit, we have adopted 51 micro controller systems as electronic control unit, independently make circuit card, independently write control program; For obtaining the gas of suitable pressure, we have adopted high-pressure gas bottle storing carbon dioxide gas, and can output in cylinder after the suitable reducing valve decompression of two-stage; Consider the lightweight of car load and the rationality of system, cylinder will select specification just to meet according to observed data; The design of hand clutch mechanism will, according to the operating habit of chaufeur, will be coordinated master layout simultaneously and arrange and human engineering setting; The reasonable work of system, need to repeatedly debug according to real vehicle operation conditions, has reached work the best.
Compared with prior art, the beneficial effects of the utility model are: gearshift of the present utility model is by the gearshift button on crawl bearing circle, under the combined action of pressure device, electromagnetic valve and cylinder, micro controller system, can realize gearshift and clutch, shift process is rapidly stable, compare traditional armstrong's patent gear shift operation, this system operating process is easy, and reaction is quick, simplify technician's burden, be beneficial to the automation control that realizes FSAE racing car.
