Analytical Studies and Calculation of the Main Parameters of the Hydromechanical Damper of the Vehicle

The article presents materials concerning the development of a promising design of a hydromechanical damper mounted in a suspension, equipped with L-shaped channels, capable of automatically changing its damping characteristics depending on the condition of the roadway and the speed of the crew. The proposed technical solution will improve the smooth running of vehicles and, as a result, the comfort and safety of passenger and cargo transportation, not only due to the dissipative forces arising from the flow of hydraulic fluid through the throttle channels of variable cross-section, but also due to angular deformations of the elastic composite rod. The analytical studies carried out, as well as hydrodynamic and strength calculations of such important parameters as the pressure of the working fluid, torques arising on the elements of the composite rod, allow us to calculate their geometric parameters, check them for rigidity, stability, calculate the twist angles, make recommendations on the choice of material.
