VEHICLE SPRING DEVICE Russian patent published in 2021 - IPC B60G11/14 

FIELD: mechanical engineering.

SUBSTANCE: vehicle suspension device comprises upper and lower lugs and a hollow cylindrical body. A guide cone with a hole along its axis is located inside the cylindrical body. The cone is rigidly connected to the base of the hollow cylindrical body. A torsion spring is coaxially located on the guide cone. One end of the spring is fixed to the base of the body, the other on a rotating disk around its axis, which is placed in a thrust bearing held in the lower part of the body by a retaining ring. A movable rod is located inside the guide cone. The end of the stem is made with a lower lug for fastening with a bridge. The movable stem has a trapezoidal thread. A rotating disc around its axis has a similar thread. The movable rod passes through a rotating disc around its axis, which is rotatable due to the trapezoidal thread around the movable rod. In its upper part, the rod with the base of the body is rigidly connected by a hollow cover with an upper lug connected to the vehicle frame.

EFFECT: increased smoothness and stability of vehicle movement.
