Appl. No.:

16/679977

- Moline IL, US
Steven R. Whiteman - Dubuque IA, US

International Classification:

F16H 1/22
E02F 3/76
E02F 3/84

F16H 1/20

Abstract:

A circle drive for rotating a blade on a draft frame of a motor grader includes a circle gear mounting the blade, a worm wheel, a torque dividing arrangement, and a single input provided on a first shaft. The torque dividing arrangement includes a set of shafts positioned about the worm wheel, a torque dividing gear set, and a set of worm gears meshed with the worm wheel. The worm wheel is operatively coupled to drive the circle gear. The set of worm gears includes a first worm gear on a first shaft and a second worm gear on a second shaft. The single input is configured to provide a driving torque that drives the set of worm gears such that the set of worm gears divides the driving torque. The driving torque is capable of driving the worm wheel for driving the circle gear and rotating the blade.

Abstract:

A fluid control system that has a fluid assembly with a piston defined within a chamber, an electrical system having a motor configured to selectively reposition the piston, a controller in communication with the electrical system, and a sensor in communication with the controller to identify a fluid pressure value. Wherein, the controller identifies a desired fluid pressure range and selectively repositions the piston with the motor until the fluid pressure value is within the desired fluid pressure range.

International Classification:

B62D 55/104

Abstract:

A suspension system supports a chassis relative to a crawler mechanism including a continuous track. A link is rotatable about an axis extending transversely through a first portion. The first portion includes a projections extending radially inwardly, and peripheral openings defined by spaces between the projections. An axle member secured to the crawler mechanism includes peripheral shafts extending radially outward from the axis and positioned in an associated peripheral opening. Each resilient member is positioned within an associated peripheral opening and engages an associated peripheral shaft, damping movement of the peripheral shaft relative to the link. An auxiliary roller assembly includes a yoke and a plurality of auxiliary rollers coupled to the yoke. The yoke is rotatable relative to the crawler frame about a yoke axis. The auxiliary rollers are aligned along a direction of travel of the track and are configured to engage an inner surface of the track.

International Classification:

B62D 55/108
E02F 9/20
E02F 3/34

Abstract:

A suspension assembly of a work machine being movable in a forward direction. The work machine includes a frame, an undercarriage supporting the frame and at least one ground-engaging track. The suspension assembly includes a torsion assembly having an axle, a torsion bar adapted to be fixedly coupled to the frame, and an axle arm coupled at one end to the axle and at an opposite end thereof to the torsion bar. A locking arm has a first end and a second end, where the first end is coupled to the axle arm. A hydraulic actuator is coupled to the second end of the locking arm. The hydraulic actuator is operably controlled between a locked configuration and an unlocked configuration. In the unlocked configuration, the axle arm is pivotable relative to the frame, and in the locked configuration the axle arm is restricted from pivoting relative to the frame.

F16H 9/04

Abstract:

A fan assembly may include an input shaft, first and second belts, first and second pulleys engaged by the first belt, third and fourth pulleys engaged by the second belt, output shaft rotationally coupled to a fan, and a clutch assembly. The second pulley may be rotationally coupled to the first pulley via the first belt so as to rotate in the same direction as the first pulley. The fourth pulley may be rotationally coupled to the third pulley via the second belt so as to rotate in the opposite direction of the third pulley. The clutch assembly may be configured to selectively rotationally couple the output shaft to the input shaft via the first pulley, first belt, and second pulley. The clutch assembly may also be configured to selectively rotationally couple the output shaft to the input shaft via the third pulley, second belt, and fourth pulley.
