FOUR-POINT LEVER Russian patent published in 2017 - IPC B60G7/00 B60G9/00 B60G21/05 

FIELD: machine building.

SUBSTANCE: invention relates to cargo vehicle axis suspension four-point lever. Four-point lever has four supporting seats (3), from which two supporting seats (3) are made with possibility to be articulated with vehicle axis and two supporting seats (3) are made with possibility to be articulated with vehicle frame. Four-point lever includes made with possibility of torsion, substantially, inscribed into formed by supporting seats (3) trapezoid lever body (1, 2), formed of structure from fibrous composite. Structure from fibrous composite comprises structure (10, 11) with longitudinal fibres matched with supporting seat (3), which covers supporting seat along half of its perimeter, and also passes along lever body (1, 2) parts. Lever has two structures (10, 11) with longitudinally oriented fibres, each of which is associated with one of two pairs (3) of diagonally opposite supporting seats.

EFFECT: enabling possibility to produce lever monolithic body with crosswise arranged ribs from unidirectional fibers, which provides high capacity for perception of loads, higher fatigue strength due to elimination of stresses concentrators and reduced structure weight.
