摘要： A coupler for coupling implements having a first connecting pin and a second connecting pin, to a vehicle, for example, to the arm of an excavator. The coupler has a body component that is connectable to the vehicle, and which includes a forward recess for receiving the first connecting pin. The coupler also includes a movable component which is supported by the body component and which has an aft jaw or recess for receiving the second connecting pin and is movable through a range of travel relative to the body component. The movable component includes a rear locking member which is movable between an extended position in which the rear locking member can prevent the second connecting pin from exiting the aft recess and a retracted position in which the rear locking member can allow the second connecting pin to exit the aft recess.

摘要： The invention relates to a quick connect coupling (15) for connecting hydraulic lines, especially in earth moving machines and the interchangeable add-on devices and tools thereof. Said quick connect coupling (15) comprises a first and a second connecting part (15a or 15b) which can be releasably coupled along a coupling axis to transfer a hydraulic liquid. In order to avoid axial forces during coupling, the hydraulic liquid to be transferred, in the coupled state, emerges from the one connecting part (15a or 15b) at a right angle to the coupling axis and enters the other connecting part (15b or 15a) at a right angle to the coupling axis.

摘要： The invention concerns an arrangement for the securing of an implement to a lifting arm, particularly to a front loader, where the implement and the lifting arm can be fastened to each other by a movable locking bar, which can be moved between a locking position and an unlocking position, and can be brought from the locking position into the unlocking position by a remotely actuated hydraulic cylinder. It is proposed that the locking bar can be arrested automatically in the unlocking position, with it then being possible for the hydraulic cylinder to be deactivated. The locking bar is located such that it can be brought into the locking position from its arrested position by moving the implement by another remotely actuated hydraulic cylinder such that the locking bar engages the lifting arm and is moved to a non-arrested position from where it is automatically biased back into its locking position. Furthermore, it is proposed that the hydraulic actuator for effecting movement of the locking bar be connected with an accumulator.
摘要翻译：本发明涉及一种用于将工具固定到提升臂，特别是前装载器的装置，其中工具和提升臂可以通过可移动的锁定杆彼此紧固，其可以在锁定位置和解锁位置，并且可以通过远程驱动的液压缸从锁定位置进入解锁位置。建议锁定杆可以在解锁位置自动停止，从而可以使液压缸停用。锁定杆定位成使得其可以通过由另一个远程驱动的液压缸移动工具而从其停止位置进入锁定位置，使得锁定杆接合提升臂并且移动到非停止位置被自动偏置回其锁定位置。此外，提出用于实现锁定杆的运动的液压致动器与蓄能器连接。

摘要： A heavy-duty machine, such as an excavator, having a boom mounted for motion in a generally vertical arc, a stick mounted onto the distal end of the boom, and a tool mounted at the distal end of the stick. The stick is connected to the boom by a quick-disconnect coupling including a coupling member that is rockably mounted at the distal end of the boom and a coupling member mounted at the proximal end of the stick. A grab hook on the boom coupling member is used to pick up the stick by hooking onto a grab pin of the stick coupling member. A set of rack gear teeth on the boom coupling member intermesh with a corresponding set of rack gear teeth on the stick coupling member, and these eliminate play between the stick and boom. A quick-disconnect hydraulic coupling including a female coupling element mounted on the boom coupling member with a remotely operable locking means, and a male coupling element mounted on stick coupling member provide automatic coupling of hydraulic lines between the boom and stick when the coupling members are brought together.

摘要： An arm assembly for a work vehicle includes an arm configured to rotatably couple to a chassis of the work vehicle. The arm includes a substantially vertical portion, and the substantially vertical portion is configured to support an implement. The arm assembly also includes a lift actuator coupled to the arm and configured to couple to the chassis of the work vehicle. The lift actuator is configured to rotate the arm relative to the chassis to control a position of the implement along a vertical axis. In addition, the arm assembly includes a support actuator configured to couple to the chassis. The support actuator is configured to engage the substantially vertical portion of the arm to support the arm against a horizontal load applied to the arm by the implement.
