What is the device PGU of KAMAZ-5320? This question interests many beginners. This abbreviation may cause confusion in an ignorant person. In fact, PSU – pneumatic-hydraulic power steering. Consider the features of this device, its working principle and types of services, including repairs.
A Truck – a fairly massive and bulky appliances. Its control requires a remarkable physical strength and endurance. Device PSU KAMAZ-5320 allows easy alignment of the vehicle. This is a small but useful device. It allows not only to simplify the work of the driver, but also increases productivity.
Consider the node consists of the following elements:
Cabinet amplifier system consists of two elements. The front part is made of aluminium and the rear analogue – made of cast iron. Between the parts there is a special gasket, which acts like a gasket and diaphragm. Tracking mechanism regulates the air pressure changes on pnevmoballony in automatic mode. This fixture also includes a sealing cuff, springs, diaphragms and valves on the inlet and outlet.

When you press the clutch pedal under the fluid pressure device PSU KAMAZ-5320 presses on the rod and the piston of the servo device, and then design together with the diaphragm is displaced to the opened inlet valve. Then a mixture of air from the pneumatic system of the vehicle is supplied to pnevmoballony. The result of the cumulative efforts of both elements that allows to remove the plug and turn off the clutch.
After the foot is removed from clutch pedal, the pressure of the inlet main fluid drops to zero indicator. As a result, decreases the load on the hydraulic pistons Executive and a tracking mechanism. For this reason, the hydraulic type piston begins to move in the reverse direction, closing the inlet valve and blocking the flow of pressure from the receiver. Diaphragm spring acting on the servo piston, carries it in its original position. Air, initially reacting with pneumatic piston vented to atmosphere. Stock with both piston returns to the starting position.
Device PSU KAMAZ-5320 suitable for many model modifications this manufacturer. Most of the old and new tractors, dump trucks, military variants equipped with a pneumatic servo. Modern versions produced by different companies, have the following meaning:
In terms of amp selection specialists recommend to buy the same brand and model that was originally installed on the machine.

To maintain the operational state of the node carry out the following activities:
It is Worth noting that when adjusting the PSU KAMAZ-5320 modification Wabco, wear of clutch linings easily visible on a special pointer that put forward under the influence of the piston.
This procedure whennecessary, is performed in the following order:
Most Often in the considered node are having problems of the following nature:
Through the Troubleshooting of node elements, special attention should be paid to the following points:
Repair kit PSU includes spare parts KAMAZ:
Before Assembly all parts should be treated with a lubricant of a type “lithol”.
To replace the considered node, perform the following manipulation:
After replacing the warped and worthless elements, the system is checked for leaks in the hydraulic and pneumatic parts. The Assembly procedure is as follows:
The Principle of operation of combined-cycle plant of KAMAZ-5320 easier to understand after examining the scheme presented below, with explanations.
The Reporting node is quite clear and simple device. However, its role in the management of trucks is very significant. The use of CCGT allows to significantly facilitate control and increase the efficiency of the vehicle.
