摘要： A joint orientation system is provided for a work vehicle having a chassis and an implement coupled to the chassis at a joint. The joint orientation system includes a first IMU positioned on a first side of the work vehicle relative to the joint and configured to collect a first IMU acceleration and a first IMU angular velocity and a second IMU positioned on a second side relative to the joint and configured to collect a second acceleration and a second angular velocity of the implement. A controller is configured to receive the first and second IMU accelerations and the first and second IMU angular velocities; determine a joint orientation correction based on IMU accelerations and IMU angular velocities; modify an estimate of joint orientation with the joint orientation correction to generate a current joint orientation; and output the current joint orientation for actuation of the implement.

摘要： A quick coupler circuit includes a cylinder to attach and/or detach an attachment to and/or from a construction machine by expansion and/or contraction, a flow pump to supply fluid to the cylinder, a valve through which fluid for operating the cylinder passes, a spool valve which includes a spool, to move along an axial direction, and to form a pressure at a node of the flow pump according to movement of the spool, an electronic proportional pressure reducing valve to control the spool valve, a switch to perform an ON/OFF operation, and a controller to output a control current to the electronic proportional pressure reducing valve in response to the operation of the switch. The controller is maintains control current which it outputs during the switch's ON operation for a predetermined period of time after the switch's OFF operation.

摘要： A pin grabber coupler and method for locking and unlocking a tool to a machine is disclosed. The pin grabber coupler may comprise a tertiary lock configured to pivot between an unlocked TL position and a locked TL position. The tertiary lock may include a first and second shoulders, a leg, a tab, a latch, a bias member and a detent. The bias member may be configured to exert a biasing force on the tertiary lock to urge the tertiary lock to the locked TL position. The detent may be configured to exert, when in a hold position, a holding force against the latch that is greater than the biasing force exerted by the bias member. When the detent is in a release position, the holding force applied by the detent against the latch is less than the biasing force applied by the bias member.

摘要： A quick hitch for coupling a tool to an excavation arm of an excavator. The quick hitch comprises a connector comprising a first end coupleable to an excavation arm, and a second end coupleable to a tool; and a latching member releasably engageable with the second end of the connector. In use the second end of the connector receives the tool, and the latching member engages with the connector to releasably couple the tool to the connector.

摘要： The present disclosure is directed towards a coupling assembly (13) for a machine (10). The coupling assembled comprises a pin (27) comprising at least a first pin passageway (31) for lubricant extending between a first pin passageway inlet (32) and a first pin passageway outlet (33) for directing lubricant outside of the pin (27). The coupling assembly (13) also comprises a distribution device (28) for distributing lubricant comprising at least one distribution device inlet (45) for receiving lubricant and at least one distribution device outlet (46, 62, 47, 48). The distribution device (28) is mounted to the pin (27) and the at least one distribution device outlet (46, 62, 47, 48) is arranged to direct lubricant into the first pin passageway inlet (32).

摘要： A skid-steer implement allows for the rotation of a tool attachment relative to the body of the skid-steer by coupling an attaching element and a rotation attachment device with a shaft and force generating devices. The slim construction of the device allows for bucket rotation while limiting the tipping load change caused by the extension of the implement.
