The heavy Panrah (transverse bar) is part of the vehicle suspension structure, a special lever that records the transverse displacement of the suspension of the body. The traction prevents unwanted side movements of the car axle. History of inventions
History of inventions
René Panar and Emil Levassan-owners of the French car company and talented engineers, in addition to the production of cars, have constantly studied and improved their technical characteristics. René Panaru belongs to the development that perpetuated his name: the thrust of Pan was invented in the early 20th century and became a long-term standard for car suspension throughout the world. Naturally, the first cars on which the thrust was installed were the cars of Panhard et Levassor.
How the Pan's thrust works
One of the main functions of the car suspension is to provide the wheels with the ability to move vertically. Transverse movements, along with movements along the hull, are very undesirable. It is the thrust of Pan that prevents such oscillation of the car axis.
The heavy Panrah is a rigid pipe, one end of which with hinges is fixed on the frame or body and the other end on the beam of the bridge. Thrust balls (salos) have only one degree of mobility-that is, they allow the bridge to move vertically (under load, uneven road), but not allow to blend in.
This draught line is placed on the back dependent signs in passenger cars, and on some SUVs and trucks on both suspension bridges.
Panare's traction is practically not used on spring suspension in serial production, as the springs are usually capable of controlling all the movement of the bridge. But the installation of this element on spring suspension is quite common in the tuning of the cars-the drive is able to significantly improve the driveability of the car, as it compensates for the transsoreness of the springs in the transverse direction.
The design of the Panare thrust may be:
- solid (unregulated). Such thrust only serves its immediate functions;
- Massacre. In addition to the main functions, the lever is used to adjust the height of the bridge, as it is controlled. This design is convenient and functional, so it is produced serially. The service is very popular-in the service, or can be made out of solid traction-a rivelled.
Advantages and disadvantages of the Panama Canal
The advantage of Panrah's thrust since its invention was a simple design and a low cost.
The lack of the Panare thrust design is not ideal for turning the bridge to the left to the right about the body. This creates problems with the driveability of the car. This is why, in the spring-loaded front lines, the thrust of the Panamas is usually used together with the rails, they control the longitudinal and lateral moves of the bridge and compensate for the drawbacks.
It is believed that better alternative devices, which create an even resistance to lateral forces, are the mechanism of Watt and the Scott-Russell mechanism. But their installation costs more than the use of the thrust of Panama.
Operation and repair
The modern propulsion of the Panamas is made of metal bars of high elasticity. The attachment to the body is used by the polyurethane and rubber metal joints, and the threaded nut carvings are used for fine-tuning. Generally, traction is anti-corrosion coating or special paint.
Checking of the thrust is to control its general condition and to inspect the anchorages for cracks and corrosion signs. The weight can be curled or deformed if the car often travels on a bad road-it is attached very low and may undress the road at unevenness. Small cracks can eliminate the welding, and the deep cracks require the replacement of the traction.
