MOTOR GRADER Russian patent published in 2017 - IPC E02F3/76 

FIELD: construction.

SUBSTANCE: motor grader includes a wheeled propulsor, a sub-engine frame and a main beam, mounted on the propulsor and connected by a hinge and hydraulic rotation cylinders, to the front end of the main frame a traction frame with a turntable is hingedly mounted, on which a blade is mounted with mechanisms for changing its the cutting angle and extension, hydraulic cylinders for lifting and lowering the blade. The rotation axis of said hinge is located in the vertical plane with an inclination at an acute angle to the supporting surface of the motor grader, and the hinge body is configured to be fixedly rotated about an axis located in the vertical plane at an acute angle equal to the acute angle of inclination of the hinge rotation axis and having a geometric point of intersection with said hinge rotation axis. Wherein the geometric intersection point of the hinge axes and the hinge body can be located in the hinge body or outside the hinge body.

EFFECT: expanding the functional capabilities of the motor grader, in particular by manageability, while putting the blade in the working position, maneuvering and working on slopes.
