Abstract:
A steering mechanism and guidance system for a milling attachment device provides steering capability without impeding cutting depth control. The steering mechanism has at least one wheel that is rotated by an actuating mechanism such as an extending cylinder, synchronized actuators, or the like. The steering mechanism may be integrated with depth control by using a parallelogrammic structure with pivot points to assist in the depth control or may operate independent of and without impeding depth control.

Claim (Index 12):
A steering mechanism to provide steering capability for both a host vehicle and for a milling attachment separate from, but connectable to the host vehicle operated by an operator, the host vehicle providing propelling force to the milling attachment, the milling attachment having an outer frame, a height-adjustable inner frame, and a rotating cutting head fixed to the inner frame so that the cutting depth of the rotating cutting head depends on the adjusted height of the inner frame relative to the outer frame, the steering mechanism, comprising:\n an attachment mechanism configured to connect a milling attachment to a host vehicle; a first wheel mounted to a first pivot shaft; a second wheel mounted to a second pivot shaft, the outer frame being supported by the first wheel, the second wheel, and the host vehicle;\n a support bar disposed across the front of the milling attachment forward of the rotating cutting head and connected to the outer frame, the support bar for receiving a first arm in pivoting engagement and a second arm in pivoting engagement, the first arm receiving the first pivot shaft in pivoting engagement and the second arm receiving the second pivot shaft in pivoting engagement, wherein the first arm and the second arm are each pivotally movable from a forward mode to a side mode enabling the front of the milling attachment to advance proximate an obstacle while maintaining steering capability; \n a first steering actuator connected to and providing powered rotary motion to the first pivot shaft and the first wheel; a second steering actuator connected to and providing powered rotary motion to the second pivot shaft and the second wheel; a guidance system configured to indicate the alignment of the steering mechanism in relation to a predetermined path; and milling attachment steering controls positionable for access and actuation by the operator within the host vehicle to steer the milling attachment and the host vehicle, the steering controls being connected to the first steering actuator and second steering actuator of the steering mechanism allowing an operator to control steering of both the host vehicle and the milling attachment by activating the first steering actuator and the second steering actuator.
