Hydrodynamic Brakes
A spring manufacturing firm in Sweden offers some useful information concerning hydrodynamic brakes. A brake is any kind of tool used for slowing or stopping the turning of wheel or the movement of a car. There are also cases in which the brakes are applied to keep a stopped automobile from moving like when parking on sloped surfaces. Brakes work by transforming the kinetic energy into warmth.
There are two main types of brakes: friction brakes and hydrodynamic brakes. Almost every type of bake makes use of friction in order to operate. The friction brakes operate by pressing an object to the moving component. In a drum brake, applying the brake causes the brake pads to be pushed towards the spinning the drum which is attached to the wheel. The brake springs pull back the brake pads when the brake is not being applied.
There are some applications in which hydrodynamic brakes are much better compared to the traditional friction brakes. These brakes are generally used to supplement traditional brakes on many large vehicles.
Hydrodynamic brakes function with the aid of a fluid's resistance to movement The key components of the hydrodynamic brakes are the rotor and the impeller. The impeller is comparable to the propeller and shaft found in boat motors.
The rotor is affixed to a revolving shaft of the impeller. The impeller is immersed in a liquid which remains in a secured container. As the impeller turn, the liquid's resistance to movement provides a stopping action. The kinetic energy is converted into heat. This causes the temperature of the liquid to increase. The liquid can be cooled using a radiator.
