Jekit Car Brake Parts 330*28mm Cast Iron ARC Groove Disc For Front
Product Description
The material of Jekit brake discs adopts my country's gray cast
iron 250 standard. The requirements for the three main elements of
the chemical composition are: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9.
Mechanical performance requirements: tensile strength>=206MPa,
bending strength>=1000MPa, deflection>=5.1mm, hardness
requirements between: 187∽241HBS.The carbon and silicon content in
gray cast iron is generally controlled at 2% to 4% C, 1.0% to 2.0%
Si, and 0.5% to 1.4% Mn. Gray cast iron has good casting
performance, good vibration damping, good wear resistance, good
cutting performance, and low notch sensitivity.
Mechanical performance requirements: tensile strength> 21on/mm,
hardness requirements between 187 and 241, and some special or
high-end models also use ceramics, high-carbon double aluminum
alloys, etc.
There are disc brakes, drum brakes and air brakes. Older cars have
front and rear drums. Many cars have disc brakes both front and
rear. Because disc brakes have better heat dissipation than drum
brakes, they are not prone to thermal decay under high-speed
braking, so their high-speed braking effect is good. But at low
speed cold brakes, the braking effect is not as good as drum
brakes. The price is more expensive than the drum brake. Therefore,
many mid-to-high-end cars use full-disc brakes, while ordinary cars
use front and rear drums, and relatively low-speed trucks and buses
that require a large braking force still use drum brakes.
Drum brakes are sealed and shaped like drums. There are many brake
pots in China. It turns when driving. Two curved or semicircular
brake shoes are fixed inside the drum brake. When the brake is
stepped on, the two brake shoes are stretched out under the action
of the brake wheel cylinder, supporting the brake shoes to rub
against the inner wall of the brake drum to slow down or stop.
1. Disc brakes have better heat dissipation than drum brakes, and
they are less likely to cause brake degradation and brake failure
when the brakes are continuously stepped on.
2. The size change of the brake disc after being heated does not
increase the stroke of the brake pedal.
3. The disc brake system responds quickly and can do high-frequency
braking actions, so it is more in line with the needs of the ABS
system.
4. Disc brakes do not have the automatic braking effect of drum
brakes, so the braking force of the left and right wheels is
relatively even.
5. Because the brake disc has better drainage, it can reduce the
situation of poor braking caused by water or sand.
6. Compared with drum brakes, disc brakes are simple in structure
and easy to maintain.
