Bendix Air Board Overview 1

hi my name is Kyle sponsoring I'm here with the Bendix airborne from Stanford mechatronics lab and this board is very good representation of an air brake system on a straight truck so the first thing that a truck driver is going to do when he gets up into his truck good morning is he's going to want to release his parking brakes this is down to the PVC push pull - control valve and when you push this button in it's going to send a control signal through the yellow line up to the sr7 which will relay that signal using a secondary system to apply air to the parking sides of the other shirt the reason that we have to apply air to the parking brakes to release them is because there's very large power swing in there that is always acting on it and we need to build air on that diaphragm to gauge that power spring so when I push this button in and you're going to see the push rods retract because the power spring is being compressed now that we have the parking brakes from Beast now we're freely able to drive down the road so now we're driving down the road and there's a red light and we need to stop so now we're going to use our service brakes to be able to slow the truck this is done using the dual circuit foot brake valve here with the throttle on top and this is fed with the primary circuit denote a degree and a secondary circuit to get noted an orange so the secondary circuit is generally used for the steering axle and the green primary is used for the drive axle back here so when you press this foot brake down it's going to send a signal through here allowing supply to then go to delivery and it's going to come out through the ABS modulator which is used for ABS and ESP and then go through the earth out to the actuator which is going to apply force on the diaphragm there and then transferring that force to a push rod similarly we have the primary circuit when you push the foot brake at the same time it's going to send a signal through this line to the relay the reason that we have a relay here is because the distance between the foot brake and the rear brakes could be very long so we send a control signal that will receive will be received here very quickly and it has some wire waiting on it with very large lines so one build pressure on top of this piston it then allows supply to deliver and you can send aired here your service breaks much much quicker so after you go through this relay you go through the ABS modulators again we have one per every wheel line and it goes into the ever sure again so the ever shooter is different than the actuators over here because it has both parking and service the service section is this black section here and the parking is this bigger end over here and the service sides act identical to each other so we apply air into them the brakes come on and then as I was saying before the parking brakes when you apply air to indignities so that is a brief overview of the Bendix airport thanks for watching
