The purpose of the crane cross and the history of the creation
The need for mobile connections has arisen because the axis of the shaft of a motor vehicle does not always have one straight line. They change the position in space while the machine is in motion. This changes the distance between the horizontal and vertical planes in different horizontal and vertical planes.
The transmission of the torque from the gearbox to the driving bridges is the card connection. For the first time, the principle was described by the Italian engineer J. Cardan. Its work has served as a basis for the construction of the transmission card used in vehicle transmissions.
The carat of the shaft is a flexible connection of the motor vehicle with the driving bridge
It is composed of shaft and joints, intermediate supports, and connectors. The crossover has a special role in this system. It is the one that transfers the torque from the gearbox to the constantly changing angles when the vehicle is moving.
Device and working principle of the karmane
The carat of the shaft is, as it is clear from the name, a cruciform that ensures the soyness of all rotating elements. It connects the two forks that are part of the Tbar. The ends of the forks are attached to the four ends, or the shepam, the owls. A shaft of a shaft and one fork has a rigid anchorage.
The joinings shall be carried out with the help of the iconic bearing bearing children's bearings on the seacoids. These bearings are installed in forks located on forks and fixed by locking rings to prevent their displacement. The thickness of the stop rings depends on the size of the allowable oct.
Thus, the crusovine of the shaft is a flexible connection of the motor vehicle with the driving bridge. It is structurally perpendicular to the axis, which is based on the idylted bearings mounted on the wall plug of the shaft.
The function of the crusader consists in the provision of a mobile connection, the removal of the dynamic deformation of the joinline, and the transfer of the torque to the wheels.
The crossover case is made of alloy steel and heat treatment, which provides a high surface hardness of the thorns
The asthine is different in size. The size may depend on different factors: the car brand, its dimensions, engine power and, as a consequence, the torque values.
The body of this important feature is made of alloy steel and heat treatment, which provides a high surface hardness of the thorines. Special bearing steel and the corresponding thermal treatment are used for the production of outdoor bearings and the icons themselves.
The high efficiency gears and the longevity of the joints shall be ensured by the application on the spike of the hull of hermetically sealed bar bearings. In order to ensure the reliability of such sealing of the knots of the crane crane in the manufacture of seals of the bearings is used the benzoomnybones rubber.
Advantage and disadvantages of cardan-owl
The crusader in itself is a simple, reliable and durable element of the car.
The essential conditions for the normal operation of this site are the quality of the materials used in its manufacture and the presence of lubricant in the contact points with other elements. The theoretical work resource of the crane is 500.000 km.
At the wrong location of the gross, the connection is practically the only efficient way to transmit the rotation. The main disadvantage is that when a large angle occurs between the ramparts, their rotation becomes unevenly distributed. As a result, there is a huge loss of power during the transmission and the wear of the join nodes is increasing. The unevenness of the rotation of the gross becomes more pronounced when the angle between them is greater than 10 degrees.
Other types of mobile connections and combinations thereof
One of the alternative forms of the mobile connection for torque transmission shall be an angle-of-speed joint or a Shortest angle. This connection helps to avoid uneven rotation of the connected gross, when the angle between the connected parts is more than 20 degrees-from 30 to 70.
Passing torque in a situation of high disparity is carried out by the intermediate shaft. It consists of an elastic coupling, a flange and an equal angular velocity. The tenderness of the non-base components in such a design provides an elastic coupling. It is constructed from steel liners and rubber jumpers connected together. The transmission of the vehicle is made by the elasticity of the muff. In the structure of the shaft, the cardata connections have been applied, because there is a great disparity between the ramparts that unite the pass.
The intermediate shaft is used, for example, in the construction of the transmission of 4x4 VAZ vehicles (21213, 21214, 2131) of the Niva Lada 4x4 family. In the case of cars of the current model VAZ 21214, the data of the connection has been replaced by shruby-less noisy and not requiring adjustment of the soyness.
