Work vehicle hood actuator
View Patent ↗A position control system including an actuator having a first end, an axis and including a driving device for moving the first end of the actuator in opposed directions, the first end of the actuator configured to move a hood between an open position and a closed position. A surface is associated with the hood that is configured to interact with the first end of the actuator in response to the first end of the actuator contacting and moving the hood between the open position and the closed position. The first end of the actuator moves along the axis and remains substantially coincident with the first axis while the first end moves the hood between the open position and the closed position.

a surface associated with the hood that is configured to interact with the first end of the actuator in response to the first end of the actuator contacting and moving the hood between the open position and the closed position;
wherein the first end of the actuator moves along the axis and remains substantially coincident with the first axis while the first end moves the hood between the open position and the closed position;
the first end includes a roller device to interact with the track; and
wherein the actuator includes a rod extending to a rod adapter having the first end, the rod adapter urged by the driving device to non-rotatably move along the actuator axis, the first end of the actuator rod adapter secured to the roller device.
5. The system of claim 4 , wherein the actuator extends through an opening formed in a fixed structure to secure the actuator substantially coincident with the axis.
6. The system of claim 5 , wherein at least a portion of the fixed structure opening includes a bulb seal.
7. A position control system comprising:
an actuator having a first end, an axis and including a driving device for moving the first end of the actuator in opposed directions, the first end of the actuator configured to move a hood between an open position and a closed position;
a surface associated with the hood that is configured to interact with the first end of the actuator in response to the first end of the actuator contacting and moving the hood between the open position and the closed position;
wherein the first end of the actuator moves along the axis and remains substantially coincident with the first axis while the first end moves the hood between the open position and the closed position;
the first end includes a roller device to interact with the track; and
the roller device includes a pair of rollers.
8. The system of claim 7 , wherein the track includes a separate track for each roller of the pair of rollers.
9. The system of claim 8 , wherein the rod adapter is substantially centered between the pair of rollers.
10. The system of claim 9 , wherein the track includes an alignment plate positioned between the separate tracks.
11. A work vehicle comprising:
a motor associated with selectable movement of a frame by operator controls;
the frame structurally carrying a cab structure;
a hood position control system secured to the frame of the work vehicle comprising:
an actuator having a first end, an axis and including a driving device for moving the first end of the actuator in opposed directions, the first end of the actuator configured to move a hood between an open position and a closed position;
a surface associated with the hood that is configured to interact with the first end of the actuator in response to the first end of the actuator contacting and moving the hood between the open position and the closed position; and
wherein the first end of the actuator moves along the axis and remains substantially coincident with the first axis while the first end moves the hood between the open position and the closed position;
wherein the hood surface includes a track and the first end includes a roller device to interact with the track.
12. The work vehicle of claim 11 , wherein the actuator is located within an engine compartment between structure defining an engine compartment and a cooling component.
13. The work vehicle of claim 11 , wherein the roller device includes a pair of guides laterally surrounding the track.
14. The work vehicle of claim 11 , wherein the actuator includes a rod extending to a rod adapter having the first end, the rod and rod adapter urged by the driving device to non-rotatably move along the actuator axis, the first end of the actuator rod adapter secured to the roller device.
15. The work vehicle of claim 14 , wherein the actuator extends through an opening formed in a fixed structure to secure the actuator substantially coincident with the axis.
16. A work vehicle comprising:
a motor associated with selectable movement of a frame by operator controls;
the frame structurally carrying a cab structure;
a hood position control system secured to the frame of the work vehicle comprising:
an actuator having first end, an axis and including a driving device for moving the first end of the actuator in opposed directions, the first end of the actuator configured to move a hood between an open position and a closed position;
a surface associated with the hood that is configured to interact with the first end of the actuator in response to the first end of the actuator contacting and moving the hood between the open position and the closed position; and
wherein the first end of the actuator moves along the axis and remains substantially coincident with the first axis while the first end moves the hood between the open position and the closed position; and
an alignment plate having a surface opposite the hood surface associated with opening and dosing the hood, the alignment plate surface configured to interact with a nut and a threaded rod extending opposite from and substantially parallel to the rod adapter to substantially prevent vibration of the hood in a closed position.
