Fresh and useful info about brake disks

Написано 24.01.2017, 21:22. Автор: Carusel
An exemplary large saloon weighing 1,7 kilograms is traveling at 134 kilometre/hour down a freeway and you have to brake quickly. Let’s say the average tires can shift a overwork of 0.85 before tires falter. We will decelerate at 0.81 to avoid slippage down the freeway. Current vehicle will make a stop in approximately 87 metre and generate around 1170 kilowatt of vis viva doing so. This energy has to be transferred by the brake gear in order hold the car. If you pump current much activity into the disc rotors in mere seconds it generate lots of warmth and the amount of mass or weight in the disc rotor is emergency as to rise to current load.

A typical front disc-type rotor on a heavy sedan is around 300 millimetres in diameter and weighs around 9.5 kg. We will focus on the face wheel as it generally get 70% of the decelerative loading. A disc rotor consists of to key elements, the installation toller which fastens to the axle and the brake lining to which the passivation torque is emploied via the caliper. The friction strip or circle in this disc rotor weighs approximately 6 kilograms. In the abovementioned braking application this 9.5 kg circle will increase in Tc by around 125 Celsius in only less than 5 s. When the same 300 millimetres circle weighed 8.5 kg with a brake lining of 5.5 kilograms then the temperature increase would be along 137 Celsius. 10% magnify in Tc does not sound all that much although unfortunately heat waftage isn’t all this easy. In a 1 off application of brake an extra 10% supposedly would not make a perceptible difference. But what arises in accomplishment driving on or off the track is a series of braking applications at regular intervals. The time between applications of brake is unoften sufficient to permit the disc to recover to the ideal special temperature so you cease with an concentration of Tc increase over a period of time.
