Operating Characteristics of Lever-Blade Shock Absorbers with the Extended Mechanical Structure

Conference paper
Part of the Lecture Notes in Mechanical Engineering book series (LNME)


The torsion suspension is a widespread structure in today’s transport machine engineering. Since the torsion bar represents just an elastic element, the problem of energy dissipation in suspensions is highly relevant for its application. Hydraulic absorbers with the movable element’s reciprocating translational motion respectively to the housing or lever-type hydraulic shock absorbers of piston and vane types, with the movable element’s rotational movement respectively to the housing, are currently used as a dissipation device in torsion suspension. These absorbers only implement throttle-valve type working characteristics, associated with these devices’ functional capacities and depending on design constraints. The paper presents a synthesis of an innovative lever-blade absorber, whose performance is not related to the value of the working chamber’s inner pressure. Their essential peculiarity relates to the presence of a mechanical control loop in the structure, that determines a close relationship between the performance and the value of the shock absorber movable element displacement relative to the body. In the process of synthesis, the appropriate methods, built based on technical systems’ modeling with modified kinematic graphs, are tested. The synthesis results are shown in the form of structurally implemented samples. A comparative analysis of the samples with their basic performance determination is performed.
