THREE-AXLE TRAILER Russian patent published in 2018 - IPC B62D61/12 B62D63/06 B60G17/27 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the mechanization of agricultural production. Three-axle trailer contains a frame, three axles with wheels, a body with a system of unloading augers and a coupling device. Each axis through the beams of the respective bridges is connected to the frame through flexible spring suspension systems. Ends of the flexible spring suspension systems of the central axis are rigidly connected to the frame of the three-axle trailer. Ends of the flexible spring suspension systems of the front and rear axles facing the central axis are connected to the frame by means of articulated suspensions, and their ends furthest from the central axis by means of actuators. Each actuator contains a double-arm lever hinged on the frame, one end of which is pivotally connected to the end of the corresponding flexible spring suspension system, and the other end is connected to the actuating rod of the hydraulic cylinder.

EFFECT: optimization of the three-axle trailer layout is achieved, which allows to reduce the pressure of the wheels on the soil surface, in combination with the increased maneuverability of the trailer and the easing of its operating conditions.
