Abstract
A work vehicle having an optical system responsive to implement movements is disclosed. The implement-responsive optical system includes an optical device, such as a worklight or camera, which is coupled to the vehicle body and which produces an optical field when active. An adjustment mechanism, such as a closed loop actuation subsystem or a mechanical linkage, is coupled to the vehicle body and to the optical device. The adjustment mechanism is configured to adjust at least one operational characteristic of the optical field in response to movement of the work implement relative to the vehicle body.
Claims7
A work vehicle, comprising:
- a vehicle body;
- a work implement mounted to the vehicle body and movable with respect thereto via a boom assembly, which includes a boom arm and a hydraulic cylinder hingedly coupled to the boom arm;
- and
- an implement-responsive optical system, including:
- an optical device coupled to the vehicle body and having an optical field when active;
- and
- an adjustment mechanism coupled to the vehicle body and to the optical device, the adjustment mechanism configured to adjust at least one operational characteristic of the optical field in response to movement of the work implement relative to the vehicle body;
- wherein the adjustment mechanism includes a linkage mechanically coupling the optical device to the boom assembly, the linkage includes a light-carrying link pivotally coupled to one of the boom arm and the hydraulic cylinder and to which the optical device is mounted, and a coupler link pivotally coupled between the light-carrying link and the other of the boom arm and the hydraulic cylinder.
