摘要： A self-leveling system controlling a boom (13) and a bucket (15) by means of double acting cylinders (17, 19). The system includes a self leveling valve assembly (27) including a first valve section (27a) including a flow divider spool (41) whereby flow from the rod end of the boom cylinder (17) is divided, one portion flowing to the head end of the bucket cylinder (19). The valve assembly also includes a second valve section (27b) including a flow dividing spool (61), whereby flow from the head end of the boom cylinder (17) is divided, a portion flowing to the rod end of the bucket cylinder, as the boom (13) is lowered. The self leveling valve assembly (27) includes capability whereby, even when the bucket cylinder (19) is fully extended or fully retracted, it is still possible to operate the boom cylinder (17).

摘要： A linkage system for loading machines is mounted on two lift-arms (14) supporting a pallet-lifting fork or a bucket (22) at the ends of the lift-arms. The linkage system is so designed that when using a bucket (22) or pallet-lifting fork the linkage system will ensure that the bucket or lifting fork will take a substantially desired angular position as it is raised and lowered, without needing to make adjustments to the tilt-cylinder as the bucket or lifting fork is raised.

摘要： Bucket stop position correction apparatus which corrects automatically the stop position of a bucket under any operating conditions (the number of revolutions of an engine) to a substantially constant horizontal position in order to mitigate operation fatigue of an operator and to improve accuracy of work. This correction apparatus includes a sensor (67 or 67') for sensing an expansion/contraction speed of a bucket cylinder (27) and a controller (51) for holding an output to a driving relay (66) for a leveller solenoid (46) until a necessary time lag (Bi) is set in accordance with the data from the sensor, the relay is actuated with the time lag described above and a proximity switch (33) is turned off.

摘要： A method for automatically adjusting the position of an implement (32) for a work vehicle (10) may generally include receiving an input associated with a flow-related parameter (206) of the work vehicle as loader arms (36) of the work vehicle are being moved and determining a speed control signal (216) for the implement based at least in part on the flow-related parameter (206), wherein the speed control signal is associated with an implement speed at which the implement is to be moved in order to maintain the implement at a fixed orientation relative to a given reference point. In addition, the method may include generating a valve command signal (242) based at least in part on the speed control signal (216) and transmitting the valve command signal (242) to a valve associated with the implement in order to maintain the implement at the fixed orientation as the loader arms are being moved.
