The hinge pin of the pivot pin, which is used in the front wheel suspension of a number of vehicles. As a rule, the kingons are used in the construction of the suspension of rear drive vehicles equipped with steering gear based, for example, in the Volga GAZ-24. The details were actively used in the construction of cars at the dawn of the automobile, as it moved from horse carriages. In the era of vehicles on horseback, the "kingpin", or "shwarm", was called a massive thick rod, which, in the frame or body of the crew, had attached an apron. In the construction of the suspension of the crew, the pin was used alone, as the steering system function was carried out with the wheels of the wheel moving around each other. In the construction of the car, the number of kingpin in the suspension has increased due to the absence of a front axle, rigidly binding front wheels. The vertical axis with a vertical axis has been retained in the "suspension" construction of railway cars and diesel locomotives where the so-called "trolleys" are connected, i.e. the wheels on the general frame, which has limited mobility relative to the frame of the wagon. Constructional design and features
Constructional design and features
In the construction of the early-period cars in the suspension were almost no alternative, since the ball support was not invented at that moment. The classic pin is an axis of the tempered steel, inserted in the clip with inserted or pressed roller or needle bearings. The crest may be positioned in both a vertical and vertical position. Connectable elements, for example, a swivel fist (fastenking to the imitation), fitted with holes with holes, through which the kingpin is being used. Thus, the proms on the imitation and the turning fist are on the same rotary axis.
Later, especially after switching to the front wheel and showing the signs on the basis of the McPherson racks, the pivot function passed to them, and the functions of the support elements were assumed to be spherical support. However, the name "pin" is still used to indicate the turning point of the wheel. The disappearance of the pin of the suspension of passenger cars began in about the 1950s. The ball supports, the construction of which provides for limited mobility of the components in both horizontal and vertical planes, makes them much more practical. The point is that the kingpin is much more rigid when compared to the ball support, and when the suspension is done, the suspension begins to break down, which is much less intense with the ball support. Advantage and disadvantages of the kingpin
Advantage and disadvantages of the kingpin
The main difficulty inherent in the pin of the pin is to hold the lubricant inside the node. The swings cannot be hermetically sealed, as it is not possible to ensure the permanent light of the sealing cover to the rotating smooth steel rod. The ball supports, consisting of a spherical part with an opening in the upper part, is easy to fill with a lubricant which, in the same way, holds the hinged pin on the pivot pin. The driver also needs constant lubrication, which is kept in the right place for a limited period of time. In order to provide the maggots, the press is often supplied with press-oils, which allow syringe of the construction with a thick oil like a lithole. However, even the thick oil is gradually disappearing from the joints of the moving parts, so the knot needs regular maintenance.
In spite of the spread of practical charm pillars, the pin has not disappeared from the structure of the cars, and above all, from trucks, pickups, and special equipment. The point is that, despite the need for regular syringes, the kingpin remains the only type of connection that carries heavy loads and difficult road conditions. The ball bearings, which has a similar strength, would be too heavy and heavy, so the suspension of the "real" SUVs in the sports cars and the like cars still keep the high school units, and in the dependent front, on the basis of the whole beam of the bridge, the kingpin is not possible from a constructive point of view. The kingpin of the kingpin should be, in addition to its durability, serviceability. The central pillar of the tempered steel breaks only from superloads, and the replacement is due mainly to sealing elements and rails. They are usually for sale, and they are not expensive.
