摘要： A screen door for a cooling package of a vehicle that includes proximal and distal frame posts, screen surface, torsion bar, stationary support, torsion bracket and fastener. The proximal frame post is hingedly coupled to the cooling package, and the distal frame post can be hingedly coupled to a secondary door. Proximal end of torsion bar is fixedly attached to proximal frame post, and distal end is moveable relative to the distal frame post. Stationary support is fixedly attached to distal frame post. Torsion bracket is fixedly attached to distal end of torsion bar, and is moveable relative to stationary support. Fastener maintains torsion bracket in a desired position relative to stationary support. Movement of torsion bracket relative to stationary support applies an adjustable torsion on torsion bar, and fastener maintains the adjustable torsion. An adjustment member can be attached to fastener between torsion bracket and stationary support.

摘要： A control system for controlling a pitch of a plurality of fan blades of a variable pitch fan driven by an engine of a harvester. The control system comprises first, second, and third feedback devices that provide first, second, and third feedback signals indicative of at least one harvester temperature, an ambient temperature, and an engine load. A controller is operable to receive the first, second, and third feedback signals, lookup an initial pitch setting, generate an initial pitch setting signal, and compare the harvester temperature to a harvester temperature limit and generate a fan reversal signal if certain conditions are met.

摘要： A screen door for a cooling package of a vehicle that includes proximal and distal frame posts, screen surface, torsion bar, stationary support, torsion bracket and fastener. The proximal frame post is hingedly coupled to the cooling package, and the distal frame post can be hingedly coupled to a secondary door. Proximal end of torsion bar is fixedly attached to proximal frame post, and distal end is moveable relative to the distal frame post. Stationary support is fixedly attached to distal frame post. Torsion bracket is fixedly attached to distal end of torsion bar, and is moveable relative to stationary support. Fastener maintains torsion bracket in a desired position relative to stationary support. Movement of torsion bracket relative to stationary support applies an adjustable torsion on torsion bar, and fastener maintains the adjustable torsion. An adjustment member can be attached to fastener between torsion bracket and stationary support.

摘要： Systems for harvesting machines, transmissions for harvesting machines, and methods of operating systems for harvesting machines are disclosed herein. A system includes a drive unit, a cleaner unit, an aspirator, and a transmission. The drive unit is configured to produce rotational power in use of the system. The cleaner unit is fluidly coupled to the drive unit and configured to separate debris from air so that the air becomes cleaned air and provide the cleaned air to the drive unit in use of the system. The aspirator is fluidly coupled to the cleaner unit and configured to draw debris away from the cleaner unit and exhaust the debris in use of the system. The transmission is coupled to the drive unit and the aspirator.

摘要： A fan assembly that has a fan hub having a plurality of blades extending radially therefrom and having a variable pitch and a controller in communication with the fan assembly to reposition a pitch of the plurality of blades. The controller establishes a variable maximum pitch of the plurality of blades based on an ambient temperature.
