Vehicle Bearing
2021-04-22
The wheel is one of the most important parts of the Vehicle. However, for the automotive industry the invention of the bearing has been equally or more important. It was the Swedish engineer Sven Gustav Wingqvist who patented in 1906 this small element but with a very important function in vehicles. If you want to know more about this, please read the following reading
What parts does a bearing have?
Two rings, one inner and one outer, with raceways: they are usually made of a special steel alloy that gives them great hardness and resistance to corrosion. Thanks to this, a longer service life and a high load index can be achieved. It is the "rail" through which the rolling elements move.
Rolling elements: these are the elements that rotate between the two rings. The most common is to use balls or rollers, although you can also find bearings with cones, needles, etc. They are usually made of steel, although there are also ceramic or plastic ones.
The cage: it is the element that separates and guides the rolling elements between the two rings. It prevents the rolling elements from colliding with each other, causing them to roll instead of sliding. They can be found in brass, steel, or plastic.
Where are bearings housed in cars?
The bearings are housed in different components with the vehicle's movement transmission, such as knuckles, steering rack or gearboxes. They are usually embedded, embedded or retained by elastic elements. Although bearings are built to last the life of a car, they can also suffer from certain breakdowns.
How to know if a bearing is in bad condition?
The clearest symptom is the noise they cause from 50-60 km / h. It is usually a kind of hum located in one of the wheels. Noise is likely to increase as speed increases or corners are taken. In these cases, it is important that you make sure that it is not a defect in the deformation of the tires, suspension or wheel alignment, as they can cause similar symptoms.Another way that can sometimes be valid to diagnose the fault is check if there is play between the moving parts where the bearing is inserted.
Once they have confirmed that the noise is coming from a faulty bearing, proceed to change it, as the consequences of not changing it in time can be serious if the bearing ends up breaking.
We hope that this reading has been useful to you and that you know a little better these simple, common and at the same time important elements.
