Mechanical brakes in Automobile Engineering

Mechanical brakes

Mechanical brakes are sets that consist of mechanical elements for the deceleration or stop of axes in equipment drives. They use levers or links to transmit force from one point to another. Braking slows or stops the movement of the coupled axes. There are several types of mechanical brakes. Band brakes, the simplest brake configuration, have a metal band lined with heat and wear-resistant friction material.

Drum brakes, commonly used on the rear wheels of cars, work when shoes press against a rotating surface called a drum. Disc brakes are built with brake pads, a calliper, and a rotor. During operation, the brake pads are pressed against the rotor. Cone brakes are made with a cup and a cone, which are lined with heat and wear-resistant material. During actuation, the cone is pressed against the surface of the coupling cup.

DISC BRAKE

The disk brake may be a device for slowing or stopping the rotation of a wheel while it’s in motion. A brake disc is usually made from forged iron, but in some cases, it is often made from composite materials like carbon-carbon or ceramic matrix reinforced composites. This is connected to the wheel axle.

To stop the wheel, the friction material within the sort of restraint (mounted during a device called a brake calliper) is forced hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and the connected wheel to slow down or stop. The brakes convert motion into heat, and if they overheat, they subsided effectively, a phenomenon referred to as brake fade.

DRUM BRAKES

A drum brake is a brake in which friction is caused by a series of pads or pads pressing against a rotating drum-shaped part called a brake drum. This term generally means a brake in which the shoes press on the inner surface of the drum. When the shoes press on the outside of the drum, it is generally called a buckle brake.

When the drum is squeezed between two shoes, similar to a conventional disc brake, it is sometimes referred to as a “calliper drum brake”, although such brakes are relatively rare. A related type of brake uses a flexible strap or “band” that wraps around the outside of a drum, called a band brake.
