  • Tilt cylinder support structure
    Patent number: 8770908
    Abstract: A support structure for a tilt cylinder of a machine that controls movement of an articulating implement may include a mounting plate, vertical support plates extending outwardly from a top surface of the mounting plate, and a central and side gussets connected to the top surface of the mounting plate and to the outer sides of the vertical support plates. The gussets assist in transitioning lateral or horizontal forces on the vertical support plates to the mounting plate and the end frame of the machine to reduce fatigue cracking at the points of connection of the vertical support plates to the mounting plate. The support structure may further include first and second lower support plates having top edges spaced from each other and connected to the bottom surface of the mounting plate, and bottom edges connected to each other so that the lower support plates and the mounting plate form a triangle in cross-section to further assist in transitioning the forces to the end frame.
