Technical Area The invention provides additional damping force for vibration damping systems in vehicles and machinery. It relates to a hydraulic shock absorber system. 5 More specifically, the seal is achieved when the first and second ends press against the inner wall of the inner pipe. by forcing the hydraulic fluid to pass only through the first or / or second hole, and thus providing at least one additional damping force by increasing the flow restriction of the hydraulic fluid. at least one primary damping device with an elastomer layer and at least one secondary damping device It is related to a hydraulic shock absorber assembly containing 10. State of the Art Vibration damping systems enable vehicles and machinery to operate safely, comfortably, and efficiently. They have been used for many years to provide this purpose. Traditional hydraulic shock absorbers allow vehicles to maintain road stability. A common method for damping vibrations and shocks caused by surface irregularities. This is preferred. 15 Traditional hydraulic damper systems rely on the movement of hydraulic fluid within an inner and outer tube. It relies on the shaft to regulate the flow of hydraulic fluid through valves, converting kinetic energy into heat. It converts it into energy. However, current systems do not provide adequate damping performance under sudden and high shock loads. It may not be at that level. This situation may result in vibrations not being fully controlled and excessive 20 Under high load conditions, this can lead to rapid wear and tear on the shock absorber components. Furthermore, controlling fluid flow solely with valves reduces the flow rate of hydraulic fluid. This can lead to imbalances and insufficient vibration damping force. In the previous technique, the absence of additional damping elements to balance the hydraulic fluid flow resulted in sudden changes. This causes a decrease in shock absorber performance under impacts. 25 2 Purpose and Brief Description of the Invention The purpose of the invention is to improve the damping of hydraulic shock absorber systems used in vehicles and machinery. to improve performance, especially under sudden and high-impact loads, more effective vibration.

The load of the hydraulic shock absorber assembly (1) is 10 according to the impacts on the road surface while the vehicle is in motion. It can ride. The shaft (30) is in the extended position (UK) when unloaded, and under load It is moving towards the retracted position (R). Under sudden and high load, the shaft is in the extended position. It comes as far as (UK). According to the movement of Milun (30), there is a hydraulic connection between the inner chamber (11) and the outer chamber (21). Fluid transfer is taking place. The hydraulic fluid inside the inner chamber (11) is connected to the shaft (30) and moves together with the shaft (30). There is at least one shaft valve (31) that enables and controls the passage of the shaft (30). The valve (31) provides and controls the flow of hydraulic fluid in both directions, up and down. is doing. The hydraulic shock absorber assembly (1) will be close to a base (40) located on the lower side relative to the vertical axis. The passage of hydraulic fluid between the inner chamber (11) and the outer chamber (21), which are fixed in position as shown, 20 There is at least one base valve (41) that provides and controls the shaft (30) when the shaft (30) is under load. During its movement from the extended position (UK) to the retracted position (GK), from the inner chamber (11) to the outer chamber. Hydraulic fluid passes into the chamber (21) via the base valve (41). With the removal of the load from the shaft (30) During the movement of the shaft (30) from the retracted position (GK) to the extended position (UK) from the outer chamber (21) Hydraulic fluid passes into the inner chamber (11) via the bottom valve (41). 25 A fixed positioned near the mentioned base (40) and resembling a truncated cone There is at least one first damping apparatus (50) with the geometry.

This The resistance created during the passage of the fluid converts kinetic energy into heat energy, thus reducing the impact to 15. It dampens. When the passage of the fluid is made more difficult, more resistance is created, thus damping. The force is increasing even further. However, it is important to make the hydraulic fluid passage more difficult in a balanced way. This requires hydraulic fluid passage up to a certain level with normal difficulty. This should be ensured, and in sudden and high-impact forces, the passage of hydraulic fluid should be made even more difficult.
