DEVICE FOR DECREASE OF VEHICLE VIBRATIONS Russian patent published in 2009 - IPC B60N2/50 

FIELD: automobile production.

SUBSTANCE: invention relates to motor vehicles and serves for prevention of excessive loads due to road unevenness. Vibration decrease device contains guide rails in a form of hollow bodies with joints each connected with the corresponding part of the vehicle. Fixed ends of flexible cantilever bars are attached to one of hollow bodies symmetrically relative to their common axis. In the cavity of another hollow body there is rotary-linear transducer. It is performed in a form of screw pair. The input of screw pair is kinematically connected with reversing motor and the output with movable carriage. The carriage covers moving ends of flexible cantilever bars on which there are rollers. Profiled cams are attached to the opposite walls of the carriage. Vibration decrease device is equipped with indicator of carriage three positions and reversing motor control circuit that is connected to power source. Indicator limit switches are fixed on the face ends of hollow bodies with the possibility of regular contact with carriage. Intermediate switch is fixed between flexible cantilever bars, at the end of one of them, which form three parallel electric circuits with the corresponding indicators.

EFFECT: device portability and increase of ride smoothness and convenience of setting the mode of effective decrease of harmful effect on passengers at actual load.
