  2. Railway brake - Wikipedia

    en.wikipedia.org/wiki/Railway_brake

    The brakes were controlled from one end of the train. To release the brakes the guard wound up the rod to compress the springs, whereupon they were held off by a single ratchet under his control (although in an emergency the driver could draw on a cord to release the ratchet). When the ratchet was released the springs applied the brakes.

  3. Brake run - Wikipedia

    en.wikipedia.org/wiki/Brake_run

    Friction brakes, commonly called fin brakes, involve a computer-controlled clamping system that squeeze metal fins attached underneath the train. [1] Friction brakes can be used to slow or stop the train and are the most common form of brakes found on modern roller coasters. [1] They can involve thick metal box beams or thin metal plates.

  4. Electric friction brake - Wikipedia

    en.wikipedia.org/wiki/Electric_friction_brake

    This describes the electrically controlled drum brake principles. The brake is built with the brake shield (1) as a base that contains the mechanism. The brake shield is mounted on an axle/spindle using the holes in the centre. The brake shoes (3) are the items performing the braking by pressing outwards at the drum that covers all the innards.

  5. Brake - Wikipedia

    en.wikipedia.org/wiki/Brake

    Frictional brakes are most common and can be divided broadly into "shoe" or "pad" brakes, using an explicit wear surface, and hydrodynamic brakes, such as parachutes, which use friction in a working fluid and do not explicitly wear. Typically the term "friction brake" is used to mean pad/shoe brakes and excludes hydrodynamic brakes, even though ...

  6. Electromagnetic clutches and brakes - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_clutches...

    In an electromagnetic brake, the north and south pole is created by a coil shell and a wound coil. In a brake, the armature is being pulled against the brake field. (A-3) The frictional contact, which is being controlled by the strength of the magnetic field, is what causes the rotational motion to stop.

    A brake run on a roller coaster is any section of track that utilizes some form of brakes to slow or stop a roller coaster train.The most common type is the friction brake, often called a fin brake, which involves a series of hydraulic-powered clamps that close and squeeze metal fins that are attached to the underside of a coaster train.

  8. Electromagnetic brake - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_brake

    Electromagnetic brakes or EM brakes are used to slow or stop vehicles using electromagnetic force to apply mechanical resistance (friction). They were originally called electro-mechanical brakes but over the years the name changed to "electromagnetic brakes", referring to their actuation method which is generally unrelated to modern electro-mechanical brakes.

  9. Drum brake - Wikipedia

    en.wikipedia.org/wiki/Drum_brake

    Drum brake (upper right) with the drum removed (lower left, inside facing up), on the front of a Ford Falcon Sprint A rear drum brake on a Kawasaki W800 motorcycle. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating bowl-shaped part called a brake drum.
