Engine Components Brake

Brake is one component of a mechanical machine that is vital existence. Their brakes provide a friction force on the moving masses so that decelerates or stops. The use of brakes commonly found in mechanical systems vary their speed as the motor vehicle wheels, rotating shaft, and so forth. Meaning it can be concluded that the main function of the brake is to stop the shaft rotation, set the rotation axis, and also prevents unwanted rotation.

Mechanical braking effect is obtained by friction, and electricity with magnetic powder, eddy currents, the phase is reversed or swapping poles, etc. lain.mPada generally have a brake components – components as follows:
1. Backing plate
Made of pressed steel plates. Rear backing plate bolted to the real axle housing and the front backing plate bolted to the steering knuckle. Brake shoes attached to the backing plate which when braking will work on a backing plate. In addition to brake shoes also wheel cylinders, anchorpin, hand brake mechanism attached to the backing plate

2. Cylinder setter brake shoes
Cylinder brake shoe tuner function ensures end of the brake shoe and for adjustment rift between the shoe with the drum. In some kind of brake, instead of cylindrical setter shoes, anchor pin and the camps used separately setter shoes.

3. Brake Shoes
Arc-shaped brake shoes customized with a drum circle and comes with a canvas, riveted or glued on the surface of the brake shoe. One end is connected to the brake shoe anchor pin or bolt setter cylinder brake shoes. The other end is attached to the wheel cylinder that serves to push the shoes to the drum and brake shoe is associated with the hand brake mechanism.

4. Pegas inverting
The springs inverting function to retract the brake shoes on the drum when footing brake released. One or two inverting spring is usually mounted on the side of the wheel cylinder.

5. Brake linings
Brake linings attached to the brake shoes to increase frictional force on the drums. The materials used are a mixture of asbestos with a copper or plastic to obtain a high heat-resistant and wear-resistant. In some kind of brake, there are material differences canvas shoe brakes mounted on the first and second shoes. This canvas can be replaced if worn already experiencing.

6. Cylinder wheel
Wheel cylinders consisting of a body and a piston, serves to push the brake shoe to drum with the hydraulic pressure is removed from the master cylinder. One or two wheel cylinders are used in each of the brake unit, depending on the model. There are two kinds of wheel cylinders; one works on brake shoes in both directions, and one movement only in one direction only.

7. Drum brakes
Drum brakes are generally made of cast iron. Drum brakes are paired only given a little loose with the brake shoes and drums that rotate with the wheel. When the brake is pressed, the brake pads will be pressed against the inner surface of the drum, resulting in friction and heat cause the drum is quite high (200 ° C-300 ° C). Therefore, to prevent this drum becomes too hot there is a kind of drum around the outside given the fins are made of aluminum alloy that has a high thermal conductivity. Brake drum surface can be scratched or deformed, but this can be remedied by way turner when it is not too deep scratches.

The simplest brake block consists of a block brake which is pressed against the brake drum. Usually on the brake blocks on the surface geseknya mounted brake linings or friction material that can be replaced when worn.
Figure 3:35 principle mechanical braking

From the picture above can be seen that to obtain the same braking force, the force F is different and depends on the direction of rotation. Keep in mind also, that for a clockwise rotation when working brakes, brake blocks will be attracted towards the drum, so the bite can occur suddenly.
