OSCILLATION DAMPING METHOD AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2013 - IPC F16F15/27 F16F9/18 F16F9/49 F16F9/508 B60G17/08 

FIELD: machine building.

SUBSTANCE: inclination angle of relationship between resistance force modulus and deflection speed modulus of an elastic member is changed if current resistance force modulus differs from the specified value. The specified value of resistance force is changed depending on current deflection of the elastic member. The specified current value of resistance force is set so that it is directly proportional to modulus of current deflection of elasticity force, which is corrected to resistance force vector, of the elastic member of its static value. The device for implementing the method represents a hydraulic telescopic damper, in which the resistance force, the modulus of which depends on the modulus of deflection variation speed, is created during the suspension deflection variation. As per the first version, the damper includes a bar fixed at the compression chamber bottom. The bar has a four-sided variable cross-section in the working section of its length. At the damper compression, the bar is retracted into inner cavity of the stock. As per the second version, the damper includes two bars, as well as a compensating chamber that is separated from the compression chamber with a partition wall and partially filled with liquid. The bars are made in the form of a rotation body and installed inside the first and the second guide elements respectively with possibility of longitudinal movement.

EFFECT: preventing resonance, and minimising the resultant force acting on the under-spring mass of the transport vehicle.
