FOUR-WHEELED VEHICLE EQUALIZING BEAM SUSPENSION Russian patent published in 2018 - IPC B60G11/20 B60G5/00 

FIELD: machine building.

SUBSTANCE: invention relates to the equalizing beam suspensions. Four-wheeled vehicle with the wheel-mounted actuators equalizing beam suspension contains each wheel swiveling lever parallelogram mechanisms, including the lower lever and the upper tie-rod of the same length, pivotally connected at their ends to the traction drive bodies and the supporting frame, and two steering differential gears and one interaxle differential. In each of the steering differential gears, two co-axial tapered bevel gears are connected to the opposite sides suspensions lower levers by means of two transverse axle-arms, and engaged with these wheels those differentials bevel gears are connected to each other by means of two longitudinal axle-arms and the interaxle differential. All four transverse and two longitudinal axle-arms axes of rotation, as well as the steering differential gears transverse axes, lie in the common plane passing through the suspensions four lower arms swing axes relative to the frame.

EFFECT: enabling improvement of the suspensions overall-mass characteristics, increase in their travel with simultaneous reduction of the frame inclination angles when moving along the irregularities.
