Liquid Cooled Disc Brakes

[South Bend Clutch]

Before I venture any farther I wanted to see if there is any interest in a Liquid Cooled Disc Brake system. It would be considered a cadillac version of all the other braking systems available to you now.



Other Supplemental Braking Systems:



(Exhaust Brakes)

(Electric Retarders)

(Engine Brakes)



This system is called the (D-Brake). It would be most suitable in the heavy work situations or with a lot of stop and go, or a lot of mountainous terrain, or to the guy who has to have the best of everything.



There will be nothing in this for me. If there is an interest I will be glad to hook any of you up with the manufacture so you can buy direct.



Company Name:



Deconti Industries Inc.



Phone Number:



860-225-0720



I hope this helps someone, Peter

The owner and designer of the new braking system wanted me to clear something up. . .



John DeConti



He will put this in a better text later but for now this is what he said.





. The average person will think that you mean LCDB's inside the wheels, not the driveline. We have done the wheel thing for race cars, and 30 years from now I think they will be everywhere in wheels. But could you make another input to let the readers know that it is in the driveline as both a midmount and a transmission mount.



More about this to come!

Well he sent me the edit and insted of errasing everything and starting over I will just print what he wrote.





This system is called the (D-Brake), which is mounted at the tail end of the transmission as a supplemental brake. It would be most suitable in the heavy work situations or with a lot of stop and go, or a lot of mountainous terrain, or to the guy who has to have the best of everything. OEM brake life is improved 3 times in stop and go use, and stopping distances reduced by 30% or more. Visit http://www.deconti-ind.com/ for more info.







Well I was not to far off



I hope this clears it up a little. The braking system is awesome and worth a look.

HMMMmmm - in the 2WD vehicles, only the REAR wheels will benefit - and with the 4WD setups, wonder if the 4WD drivetrain components are capable of dealing with the added stresses?

 

[South Bend Clutch]

The reverse torque question has been asked for over 40 years with the advent of Jake Brakes, Electric Retarders, Exhaust Brakes, etc. The answer is that time has proven that the drivetrain can handle a limited amount of reverse torque without failure, otherwise none of the products mentioned above would have prospered. Braking represents about 5% of the vehicle mileage in extreme cases, mostly in the 3% range for more normal situations. There have been cases where repeated over loading of reverse torque on under rated drivelines has caused failures, but with mostly 1400 series drivelines in trucks of this size today it is no longer an issue.

Yup, just like an exhaust brake.

- and with the 4WD setups, wonder if the 4WD drivetrain components are capable of dealing with the added stresses?

IF you had one on each output shaft (unlikely) and IF the tires were able to transmitt all that force without slippage (also unlikely), you would be dividing the torque between the two shafts. It is more likely that you would tear something up during a 4WD wheel spin event when the front wheels encountered traction.



This type of braking system has been used (aftermarket to my knowlege) for many years.

What comes to my mind when I see Liquid Cooled Disc Brakes, is exactly what they use in Europe and elsehwere when the Big Rigs race. They actually use a supply of 40 Litres of water that is sprayed on the discs each time the brakes are applied. It works rather well until the water supply runs dry! After that, the brakes run redhot til they explode into flames.



Or is this system anything like what has been offered in the Range Rover and Land Rover Disco II for the last couple of years for rock creepy crawling? Drop her in Grandma, press and button and no touchy brakes regardless of grade!

Swamp Rat:



The D-Brake is a closed loop system, similar to an engine cooling system. Antifreeze circulates through the center of a copper faced disc to a radiator. The system is designed to operate at low temperatures, the heat is removed as quickly as it created, and it can do this continuously. We test our brakes on brake dynamometers for 4 hours at a time in-between inspections, and we sell them for use as an engine dyno for up to 250 HP (see website http://www.deconti-ind.com/ go to picture page at bottom).



This technology isn't like anything being used in racing, what they are doing is very primitive, and was used in logging trucks 40 years ago. They should be using our technology, like we did for the Corvette brakes, also on our website. We actually reduced unsprung weight in this redesign through use of aluminum composites, as well as eliminating brake fade, reducing wear, improving safety and all of the other good things that a properly design Liquid Cooled Disc Brake system does.

Anything ever come of this ?

Updates?

by the looks of his website (missing in action) he must have quit making it.

Any updates on this company? I would like to purchase a truck camper, and I think the driveline brake would be awesome for handling the extra payload--like trailer brakes for the truck.

 

[John - K5AWO]

All of our fire engines and ladder trucks are equiped with drive line brake retarders with no ill effects. some of these trucks have over a million miles on them, all in sudden stop and go driving under extreme conditions.



The favored brake is a magnetic brake, no fluids to boil or brake pads/bands to burn up.



If there is any interest, I will take some pictures and post them.

 

[DieselPuff]

I would be interested in seeing the pics John.



Another thought is to use an electric trailer brake (disc and electromagnetic caliper) mounted to the tailshaft of the transmission or transfercase. It would be mounted similar to the Gearvendors unit. You could then control it through a standard trailer brake controller. Anyway... just a thought.

 

[John - K5AWO]

Okay, can do DieselPuff.



will have to wait until next Monday. I am on vacation this week. I'll drop myself an email reminder to get the job done.

"The favored brake is a magnetic brake, no fluids to boil or brake pads/bands to burn up. "



Is this like the dynamic braking used on train locomotives where they reverse the polarity of the electric motors to stop? Since an electric motor is basically a big magnet.

Check out Telma Brake @ http://www.telma.com/. We were considering putting these on our ford dually but too much $$$. Besides I see a new dodge crew cab in our future

Dont forget to click on the english version at the top left of the page, I dont want to try to translate all of that :-laf

Transit buses use a driveline brake that is integral to the transmission called a retarder. It generated a lot of heat in the fluid that is dissipated by both liquid and air heat exchangers. Kinda remind s me of the system Dodge uses on the auto powered pickups.



Be forewarned, a driveline brake does require serious cooling capacity no matter the design. The friction material has a very small window of operating efficiency.

Check out Telma Brake @ http://www.telma.com/.

Thanks SuperSonic... . All I could think of earlier was it started with a 'T'.



Telma Brake is the vendor for our Fire Trucks. All that is done is to apply current to the fields which tries to 'stop' the rotation. It is very effective. Without the Telma system, trying to stop a big ladder truck with only brakes results in one or maybe two stops max. Then it is time to see the mechanic to get new brakes. They get so hot, the lining cracks and breaks up. Smells like holy hell too.



Even on the smaller fire engines, if the Telma system isn't turned on, the truck will only make about 4 or 5 hard stops before ruining the linings and pads.



On the locomotives, the engineer can control the effect from just simple retard to full reversal of the applied voltage. They also have normal brakes on them for easy stops and to keep it from rolling when stopped.
