Spring – a French word, which translates as "spring". This detail of modern car suspension once widely used in the manufacture of horse carriages, especially carriages. Afford horse-drawn carriage on the springs could only wealthy people. Today springs are used in the design of the suspension vehicles. The main objective of this invention is the provision of smoothness-smoothing of shocks caused by irregularities in the road. This detail not only makes a comfortable ride – this element helps to deliver to your destination in a safe, secure fragile cargo, and that led to further major use of leaf springs on the trucks.
Under the smoothness designers mean how the vehicle is bumpy. The main factor influencing trescot" is the frequency of oscillation of the car, constructed on the suspension. The frequency is dependent on the ratio of mass to stiffness vertically. If the mass increases, the stiffness of the spring should be greater and Vice versa. The problem of the use of springs in small cars that favorable stiffness is achieved by increasing the load (cargo), which may be different. Therefore, the higher it is, the more comfortable car. But, statistics show that most passenger vehicle is operated at minimum load (one driver in the cabin); therefore, the leaf springs are mainly used when creating the trucks.
The most common type of spring – mnogoletniy. This design includes a few sheets, made of carbon steel, is considered to be more reliable. Such a suspension member consists of several thin metal sheets (usually 7), strapped into a single package by means of a Central bolt. The first sheet on top of it, thicker than the others, at least 1 mm. the Upper side of each sheet in the manufacturing process is subjected to shot peening to increase the service life.
To eliminate lateral displacement of the sheets, they are additionally tightening the clamps, the number of which is not less than 3. Each clamp is attached to the bottom sheet by means of metal rivets. The top ends of the clamp are pulled together by a nut, bolt or stud. The ends of the top sheet are bent in the form of lugs through which the part is fixed to the vehicle frame. The mount is not directly, but through the brackets made from ductile iron. Inside the tabs of the top sheet of the inserted rubber grommet that provides a soft and at the same time a reliable connection of the spring with a longitudinal member of the frame. Care springs is simple and consists mainly in tightening the clamps and cleaning leaves dirt.
