The problem of ringing braking effect provides the exhaust apparatus and method of a kind of static racing car braking system.
The present invention is achieved by the following technical scheme: a kind of exhaust apparatus of static state racing car braking system, including steel
Pedestal processed is fixed with the pedal otic placode and carbon fiber footrest of support rod and left and right distribution on steel base, is arranged on pedal otic placode
There is the brake pedal that one end is hinged with it, the spring connecting with the two is provided between brake pedal and steel base, braking is stepped on
The top right side wall of plate is provided with carbon fiber face sheets, and the left of brake pedal is provided with master cylinder, master cylinder lower end hinge
Be connected to the master cylinder connecting rod fixed with steel base, master cylinder upper end be provided with one end be connected thereto, the other end with
The hinged balancing pole in brake pedal upper end, the fluid reservoir that supporting bar top is provided with brake disc and is connected to master cylinder, system
It is provided with the brake caliper for cooperating with it and being connected to master cylinder on the outside of the end face of Moving plate, deflation spiral shell is provided on brake caliper
Bolt.
By adding brake pedal and steel base in structure design, reasonably connect by master cylinder and to brake disc
Connect, by brake pedal can fast power-saving carry out braking system exhaust operation, and using pedal brake pedal carry out
Exhaust, while improving exhaust efficiency, exhaust effect is also increased dramatically, and overcomes existing racing car braking system using artificial
Exhaust there are problems that exhaust effect it is poor, it is time-consuming and laborious and influence braking effect.
The angle [alpha] of master cylinder and brake pedal is 10-90 °.
Horizontally disposed adjustment hole there are four being opened on pedal otic placode, and the distance between adjacent adjustment hole X is 13-54mm.
The position for being hinged on adjustment hole by adjusting brake pedal adjusts the angle of brake pedal, and then changes the system of trampling
The direction of dynamic pedal force.
Carbon fiber footrest and carbon fiber face sheets are formulated by epoxy resin and T-31 curing agent 4:1 in mass ratio
, and the compacting of the outer surface of carbon fiber footrest and carbon fiber face sheets is bonded with 16K carbon cloth.
The setting of carbon fiber footrest and carbon fiber face sheets can play position-limiting action to foot, prevent from stepping on trampling braking
When plate, foot is slid.
The equation of braking system capacity and brake force is f (x)=p1x2+p2x+p3, wherein parameter p1Value range be-
0.284 to -0.213, parameter p2Value range be 5.26 to 7.26, parameter p3Value range be -4.43 to -1.78.
A kind of method for exhausting of the exhaust apparatus of static state racing car braking system, using following steps: a, adding brake fluid
Into in fluid reservoir；B, brake pedal is trampled 5-8 times after opening bleeder screw；C, bleeder screw is closed, brake pedal 20-30 is trampled
It is secondary；D, brake pedal range of stepping on is not unclamped, at the same time, opens bleeder screw, the gas in brake calipers is waited to arrange
After to the greatest extent, bleeder screw is closed；E, step b-d is repeated, whether observation fluid reservoir brake fluid is sufficient, and adds brake fluid in time；f,
Whether contain bubble in the brake fluid being discharged in observation bleeder screw, success is vented if without gas；If continuing containing gas
Step e is repeated up to bubble-free in the brake fluid of discharge.
The present invention does not need more personnel in exhaust, saves manpower, improves exhaust efficiency, and in braking system
The content of gas largely reduces, so that braking effect is significantly improved, more securely and reliably, while the brake force of braking system
124N-263N is increased, the response time shortens 0.32s-0.58s, ensure that the safety of driver and racing car.
