 Заголовок сообщения: Latest and helpful info about disc-type rotor for vehicles
Постоянная ссылкаДобавлено: 24 янв 2017, 22:24 
An exemplary large sedan weighing 1690 kg is traveling at 134 km/h down a highway and you must hamper rapidly. Assume the median tires can handle a G-Force of 0.85 before tires falter. We will slack away at 0.81 to escape skidding down the freeway. This vehicle will make a stop in around 87 metre and beget approximately 1170 kW of kinetic energy doing so. This energy has to be bailed by the brake system as to hold the vehicle. If you pump this lots of activity into the disc rotors in a matter of moments it beget a lot of heat and the amount of bulk or weight in the disc-type rotor is critical in order to rise to this load.

A typical front disc rotor on a large sedan is approximately 300 millimetres in diameter and scales approximately 9.5 kg. We'll focalize on the face disc as it usually takes 70% of the braking load. A disc-type rotor composed of to main elements, the installation bell which fastens to the axis and the brake lining to which the brake torque is emploied via the caliper. The braking band or ring in current disc rotor scales around 6 kilograms. In the above mentioned brake application this 9.5 kilograms disc will increase in temperature by around 125 Celsius in only less than 5 s. If the same 300 millimetres circle scaled 8.5 kg with a friction strip of 5.5 kilograms then the Tc increase would be along 137 deg C. 10% increase in Tc does not sound all that much although by mischance warmth transfer is not all that easy. In a 1 off application of brake an extra 10% probably wouldn’t make a perceptible difference. Although what arises in accomplishment driving on or off the track is a set of brake applications at punctual intervals. The time amid braking applications is unoften sufficient to allow the disc to reconstruct to the ideal braking temperature so you cease with an concentration of Tc increase over an interval of time.
