SUSPENSION OF VEHICLE WHEEL Russian patent published in 2019 - IPC B60G15/00 

FIELD: machine building.

SUBSTANCE: invention relates to wheel suspension. Suspension contains a swivel strut, upper and lower arms, pivotally connected to the strut associated with the wheel axle, and with the body, spring, power drive. Upper part of the spring is connected to the body, and the lower part is installed in the support bowl, equipped with a trunnion pivotally connected to the left side of the frame of the lower arm. Drive is made with the possibility of damping loads and changing the height of the body, placed next to the spring and pivotally connected to the body. Lower arm is made in the form of a curved solid frame structure, made at the base with protruding ends of its sides and a tubular body, extended through these ends across the axis of the lower arm. Lever is provided with a torsion bar with a stop ledge threaded through a tubular body, rigidly connected to it at one end and pivotally mounted on the first lower bracket. Tubular body is pivotally mounted on one side on the third lower bracket, on the other – on the second. Supporting part of the drive is provided with a pin pivotally connected to the right side of the frame of the lower arm. Upper arm is missed between the drive support part and the spring, made at the base with at least two protruding parts located close to each other and provided with pins, threaded through the corresponding protruding part of the base of the upper arm, pivotally connected to it and both ends rigidly fixed on the corresponding upper bracket.

EFFECT: improvement of strength characteristics and operational properties is achieved.
