Pin Latching System for a Loader

A remote loader to tractor pin latching system is disclosed which can be actuated by gears and a DC or pneumatic motor from the cap of the tractor without descending from the tractor.

The need of a remote latching system is caused by space restrictions which were faced on new tractor programs, where the space available for the loader mounting frame allocation is getting tight and accessibility to the loader hardware is getting complicated and may even create safety concerns due to the proximity of the loader hardware to the exhaust systems where the customers would really need to get real close to them to latch or unlatch the loader from the tractor.

If the pin can be actuated remotely (which is the loader's most difficult part to reach) there is no need for the user to even raise arms for latching or unlatching the loader. He can do it from the cab seat remotely.

Therefore, a loader main pin with one or more straight grooves/veins along its axis is proposed. The straight groove/vein on the pin extends on its surface and will work as a guide and as an anti-rotation feature for the pin in order to keep it from rotating and keep its translation along its axis nicely maintained.

This same pin will have another groove in a worm-groove type. This helical groove can be of the same depth as the straight and may have 1 or more turns around the pin along its length, depending on the velocity the pin has to be displaced (described below).

On the pin's bushing, where the pin will pass through, small nubs are formed which are guiding the straight grooves of the pin and whi...
