Springs are automobile back

The spring as an elastic element of a suspension bracket of the car plays nearly crucial role in his behavior on the road and ensuring comfort to the driver and passengers. She is urged to protect a car body and the people who are in it and freights from influence of road roughnesses, having provided to a suspension bracket and wheels to follow a road profile. If it does not occur, then jolting with shock "actions" will very quickly cause damage both to human health, and technical condition of the car or crew. This word is provided not incidentally. The problem of comfort and safety of freights arose probably from the moment of the invention of a wheel at the first builders of vehicles on horse or other draft. A road condition left much to be desired in those days, and inventors turned to work which result by the end of the nineteenth century, time when the first cars appeared, was a laminated spring from spring steel.
