RESILIENT SUSPENSION WITH REGRESSIVE-PROGRESSIVE CHARACTERISTICS Russian patent published in 2014 - IPC B60G3/16 F16F1/00 F16F1/18 B60G3/14 B60G3/02 

FIELD: transport.

SUBSTANCE: invention relates to machine building, particularly, to automotive resilient suspensions with nonlinear resilient characteristics. Proposed suspension comprises lever, resilient element and extra resilient element. One end of said lever is articulated with carrier body while is connected with the wheel axle. Resilient element is composed of slightly bent long plate with one end articulated with carrier body in the lever swing plane. Lever opposite end is rigidly coupled with said lever so that plate end abuts on the lever flat surface while the plate convex side in operation interacts with the lever flat plane in run-in mode. Extra resilient element is composed of slightly bent long plate with one end articulated with the lever. Opposite end of the lever is rigidly secured to carrier body to make plate end abuts on carrier body. Plate convex side interacts with the body flat surface in run-in mode.

EFFECT: decreased load at suspension resilient element at puncture and higher stiffness at release.
