摘要： Apparatus and methods are provided for controlling a double-acting hydraulic cylinder during a load-induced rod-extending operation. The apparatus includes a activation circuit and valve for providing a flow path from a pump to the cylinder head end; a flow regeneration circuit and valve fluidly connecting the cylinder rod end and the cylinder head end and configured for providing flow from the rod end to the head end during rod extension; and a controller responsive to rod-extending rate demands and rod-position sensor signals, and operatively connected to the regeneration flow valve and the activation valve. The activation valve also includes a return valve part to control flow from the rod end to the fluid reservoir during rod extension. Both the activation valve and the return valve part are controllable by the controller independently from the regeneration flow valve.

摘要： A power train for a machine is provided having a power source and a transmission, which includes a plurality of gears configured to produce multiple output ratios when selectively engaged. The power train also has a torque converter operatively coupling the power source and the transmission. A lockup clutch is associated with the torque converter, and the engagement of the lockup clutch is restricted so that the lockup clutch is engaged only when permissible gear ratios are actuated. The power train further has a controller in communication with the lockup clutch, the controller being configured to selectively engage the lockup clutch in either a first or a second shift mode with the number of permissible gear ratios being greater in the first shift mode than the second shift mode.

摘要： Apparatus and methods are provided for controlling a double-acting hydraulic cylinder during a load-induced rod-extending operation, where the cylinder is activated by fluid supplied from a reservoir by a pump, and the cylinder has a rod end, a head end, a piston connected to a rod for engaging the load, the cylinder piston being urged toward the rod end by the load during the operation. The apparatus includes a cylinder activating circuit including an activation valve for providing a flow path from the pump to the cylinder head end; a flow regeneration circuit fluidly connecting the cylinder rod end and the cylinder head end and configured for providing flow from the cylinder rod end to the cylinder head end during rod extension, the regeneration circuit including a regeneration flow valve; and a controller operatively connected to the regeneration flow valve and the activation valve, the controller being responsive to rod-extending rate demands from an operator to control the activation valve to provide flow from the pump to the head end and to control the regeneration valve to provide flow from the rod end to the head end. The cylinder activating circuit also includes a return flow path and a return valve positioned in the return flow path and configured to control flow from the cylinder rod end to the fluid reservoir. Both the activation valve and the return valve are controllable by the controller independently from the regeneration flow valve.
