초록 ▼

An articulated tracked vehicle for agricultural harvesting which reduces damage to fields and can be driven on paved roads at reasonable speeds. The vehicle has front and rear elements, linked by an articulating joint which permits turning and rotation of one element with respect to the other. Each element is motivated by a pair of tracked power units which are hydraulically driven by a heavy duty differential between the units. Each power unit is rotatably mounted solely on a shaft sleeve of the differential and is free to oscillate vertically and independently to absorb irregularities in its path. Each unit includes an endless elastomeric track which has two rows of lugs on its inner surface. A novel drive mechanism engages these lugs to motivate the vehicle. A sealed transmission housing in each power unit protects key drive elements from environmental damage without interfering with operation of the unit. The transmission is centrally disposed within each power unit to provide further protection from damage.

대표청구항 ▼

A power unit for a tracked vehicle comprising: a) a housing capable of supporting said unit and disposed longitudinally in said unit comprising i) a first lateral bore near a first end of said housing, ii) a first fixed axle laterally disposed on said housing near a second end thereof, and extending beyond opposite sides of said housing, iii) a second lateral bore at a longitudinally central location of said unit; iv) a second fixed axle laterally disposed on an underside of said housing at a longitudinally central location of said unit, and extending laterally beyond the sides of said housing; b) a rotatable axle disposed in said first lateral bore and extending beyond said opposite sides of said housing; c) a chain drive transmission disposed within said housing comprising i) a drive sprocket, the axis of rotation of which is disposed on the centerline of said second lateral bore, ii) a driven sprocket fixed on said rotatable axle, and iii) a drive chain operationally connecting said drive sprocket and said driven sprocket; d) first and second toothed drive wheels coaxially disposed and fixed on said rotatable axle on opposite sides of said housing; e) first and second idler wheels disposed on said first fixed axle on opposite sides of said housing; and f) an endless track disposed with an inner surface there in contact with said toothed drive wheels and said idler wheels, and having lugs formed on a portion of said inner surface, said lugs being spaced to mesh with said toothed drive wheels, whereby said endless track is caused to rotate in response to power applied to said power shaft.
