Here you can get Disc Brake Working Principle. Disc brakes have been widely used in both heavy vehicles and passenger cars, despite the fact that drum brakes are predominantly used in trucks and buses.
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a “rotor” to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. Disc brakes are mostly used in motorcycles and cars.
Disc brake system is widely used on front wheels in mid-range two-wheeler such as – commuter & sports bikes. The Disc brake system is used on the front wheels of most hatchback cars, entry-level sedans & MUVs; whereas, it is also widely used on both front & rear wheels of high-end cars and SUVs in combination with hydraulic / vacuum brake actuating systems.
1. Wheel Hub: The disc rotor is attached to the wheel hub and it rotates with it. The wheel of the vehicle is bolted to the wheel hub.
2. Caliper Assembly:
The caliper assembly consist of
3. Disc Rotor: It is the rotating a part of disc brake. When brakes are applied, lots of warmness is generated which can lower the braking efficiency, so the rotor has drilled vent holes on it which dissipates the heat.
The working of a disc brake is based on Pascal law.
There are types of disc brakes. One is known as the “opposed piston type disc brake” which has pistons on each aspects of the disc rotor, and the alternative is the “floating type disc brake” which has a piston on only one side. The floating type disc brakes also are known as the sliding pin type disc brakes.
The opposed piston type is a disc brake which has pistons on both sides of the disc rotors. The opposed piston type disc brake features stable braking pressure in addition to a excessive degree of controllability. The swept regions of the brake pads are enlarged to growth braking pressure, and here opposed piston types are favored.
This is due to its benefit in which the number of pistons may be expanded to realize even distribution of pressure on the rotors from each aspects. Depending at the length of the brake pads, there are several types, including the 4-pot type which has pistons on every aspect for a complete of four, and the 6-pot type which has 3 pistons on every aspect for a complete of six.
Floating type is a disc brake which has a piston on only one side and is also called the sliding type disc brake. On the floating type disc brakes, the piston pushes the internal brake pad towards the rotor when the brakes are engaged. This generates a reaction pressure that actions the caliper itself at the side of the slide pin, pushing the outer pad towards the rotor to clamp it from each sides.
Many passenger automobile disc brakes are of the floating caliper type since this type has a relatively simple and lightweight construction, which permits for decrease production costs.
Floating type disc brakes for commercial vehicles Disc brakes are used specifically for passenger cars, but due to their consistent overall performance at better speeds and resistance to brake fade, they are gradually spreading into the commercial vehicle segment, in which drum brakes were traditionally chosen for their resistance towards wear.
