Abstract
Embodiments of the invention provide a door sealing system for an overhead door assembly of a vehicle comprises a rotating seal apparatus. The overhead door assembly includes a door frame and a door panel. The rotating seal apparatus comprises a rod, a first seal, and a second seal. When the door panel is in a closed position, the rod is actuatable, so that, when actuated, the rod is rotated, compressing the seal against the door panel and compressing the second seal against the door frame.
Claims20
A door sealing system for an overhead door assembly of a vehicle having a brake pressure system, the overhead door assembly including a door frame having a sill and a door panel moveable between an open position and a closed position, the door sealing system comprising:
- a rotating seal apparatus comprising:
- a rod arranged proximate an edge of the door frame;
- a first seal extending radially from the rod;
- and
- a second seal extending radially from the rod;
- when the door panel is in the closed position, the rod is moveable between a first position, where the first seal is spaced-apart from the door panel and the second seal is spaced-apart from the door frame, and a second position, where the first seal is engaged with the door panel and the second seal is engaged with the door frame.
A door sealing system for an overhead door assembly of a vehicle, the overhead door assembly including a door frame having a sill and a door panel moveable between an open position and a closed position, the vehicle having a brake pressure system, the sealing system comprising:
- a rotating seal apparatus including a rod, a first seal, and a second seal, the rod arranged proximate an edge of the door frame, the first seal extending radially from the rod, and the second seal extending radially from the rod;
- an actuation system including an actuation valve assembly and an actuation mechanism, the actuation valve assembly connected to the brake pressure system, and the actuation mechanism connected to the actuation valve assembly and configured to move the rod between a first position, where the first seal is spaced-apart from the door panel and the second seal is spaced-apart from the door frame, and a second position, where the first seal is engaged with the door panel and the second seal is engaged with the door frame;
- and
- a latch assembly having a curved arm configured to selectively engage and disengage the sill to respectively lock and unlock the door panel in the closed position;
- wherein when the curved arm engages the sill, thereby locking the door panel in the closed position, the curved arm further engages the actuation valve assembly such that pressurized air from the brake pressure system is applied through the actuation valve assembly to the actuation mechanism, and when the pressurized air is applied to the actuation mechanism, the actuation mechanism is configured to move the rod from the first position to the second position.
