Bushings

Bushings

Most commonly found in the automobile industry as elements of a car's suspension assembly, bushings not only minimize vibration within the engine, but they also reduce noise and shocks. In cars, bushings typically are used to connect moving parts of the engine to a vehicle's chassis in order to prevent the roughness from the road being absorbed by the engine and interior of the vehicle. The bushing allows the parts of the engine or car to move as a response to a jolt or bump in the road, but does not transfer the same amount of kinetic energy to the car body. As a result of this, bushings serve a dual purpose: they hone the car's handling while also contributing to passengers' comfort by reducing road noise and bumps. Bushings are typically constructed of a vibration or energy absorbing material such as rubber which is able to absorb the strain of the vibration without breaking. Other uses for bushings include other smaller engines such as those on motorcycles, the wheel systems on skateboards and for fastening loads onto structures.

In addition to the comfort they create for passengers in vehicles, bushings also prolong the life of machinery and lower the amount of maintenance required. Bushings protect industrial equipment and machinery components from the harmful and inefficient effects of vibration, which consists of a series of oscillations that move at a cyclic pace at varying frequencies. Vibration may come from an external source or internally, within the equipment. Internal vibration is often caused by an imbalance between equipment components and even a small amount of internal vibration can greatly increase the damage caused by continued or repeated contact between engine parts. Vibration isolators isolate the equipment to which they are attached, preventing the spread of vibrations throughout the equipment components. They are typically very simple components of a vehicular system and require little lubrication or maintenance. However, due to the strain which they are placed under, rubber pads and bushings will need replacing from time to time and so it is important to check on the state of them. Bushings can be riveted to sheet metal and are made in various designs, but most often take on a cylindrical form. In many cases, an inner cylinder of flexible material is placed inside a larger metal cylinder. For specialty applications, custom bushings can be fabricated.
