Description
Technical field
The present invention is applied to FSAE racing car shifting system, the button switch that the Pneumatic shift system can make chaufeur only need press above bearing circle can be realized the lifting gear, the manual shift action has been become to automanual system, reduced the loaded down with trivial details operation of chaufeur, improved the operability of racing car, the fast and stable of gearshift.
Background technology
Now, the gear changing mode for the list type change speed gear box generally adopts the gearshift of hand armstrong's patent: first pinch clutch lever, make disengaging of clutch, then handle pin, last slowly release clutch.Whole shift process is loaded down with trivial details, easily disperses the attention of chaufeur while shifting gears on the one hand, for safety problem has been buried hidden danger, on the other hand for the match of FSAE, the manual shift system is loaded down with trivial details time-consuming, is unfavorable for shortening fixture, obtains outstanding games results.It is the very big improvement to racing car that the hand shift system is changed to semi-automatic Pneumatic shift system, manually operated action is completed and gets final product with two cylinders of electronic control unit control, alleviated the burden of chaufeur steering vehicle, be beneficial to chaufeur and obtain better steering vehicle, improved the road-holding property of racing car, made shift process more coherent smooth and easy.
Summary of the invention
For solving the problems of the technologies described above, change existing hand shift system, the invention provides a kind of simple to operate, reaction is quick, simplify the FSAE racing car shifting system of technician's burden, utilize cylinder, electromagnetic valve, electronic control unit, plectrum, gas cylinder, the components and parts such as reducing valve have been produced a set of Pneumatic shift system, this system is by the moving lifting gear of hand of driver movable contact button, indirectly control electronic control unit, electronic control unit is actuated electromagnetic valve action according to the preset program output signal that responds, the different mode of operation of electromagnetic valve drives cylinder operation, completed self shifter.
The following technical scheme of employing of the present invention:
A kind of FSAE racing car shifting system, comprise the gas cylinder that pressed gas is provided, reducing valve, the 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 the clutch electromagnetic valve and the 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 all are connected with single chip circuit, and with single chip circuit, be connected for controlling the clutch electromagnetic valve and the clutch button of the electromagnetic valve of shifting gears and gearshift button.
Further, described gearshift electromagnetic valve is the 3 position-5 way electromagnetic valve, and described clutch electromagnetic valve is the 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, the upshift switch connection, the break-off of ECU control engine ignition system, the gearshift electromagnetic valve is connected after moving to the position that upgrades, and the drive of high-pressure gas shifting cylinder is realized the upshift action.During downshift, kickdown switch is connected, and the 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, the gearshift electromagnetic valve moves to work behind the position that lowers category, and the drive of high-pressure gas shifting cylinder is realized the downshift action.The pneumatic circuit source of the gas is high-pressure carbon dioxide gas, and the required low-pressure gas in loop is to reduce pressure and obtain by reducing valve; Circuit part is that the control function according to micro controller system is designed, and finally produces pcb board; Because cylinder is swift in motion, while starting to walk for solving, power-transfer clutch is submissive in conjunction with problem, has designed separately hand clutch mechanism, and this mechanism only works in starting and parking, and its lifting gear is to control by cylinder.
The present invention 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 the human engineering setting; The reasonable work of system, need to repeatedly debug according to the real vehicle operation conditions, reached work the best.
Compared with prior art, the invention has the beneficial effects as follows: gearshift of the present invention is by the gearshift button on the crawl bearing circle, can realize gearshift and clutch under the combined action of pressure device, electromagnetic valve and cylinder, micro controller system, 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 that realizes FSAE racing car and control.
