    摘要: In one aspect of the present invention, an electronic shift control for a powershift transmission is disclosed. The transmission includes a plurality of speed and direction changing clutches. A plurality of pressure control valves are individually connected to the clutches. A hydraulic pump delivers pressurized hydraulic oil to predetermined pressure control valves to meter hydraulic fluid in response to receiving a clutch command signal. The method produces a shift from a first transmission ratio to a second transmission ratio through disengagement of an off-going clutch associated with the first transmission ratio and engagement of an on-coming clutch associated the second transmission ratio. The method includes filing an on-coming speed clutch, releasing an off-going direction clutch in response to the on-coming speed clutch being filled, and thereafter, gradually increasing the on-coming speed clutch pressure to engage the speed clutch. Finally, the on-coming direction clutch pressure is gradually increased to engage the direction clutch in response to the on-coming speed clutch being engaged.

    摘要: A tube expander (10) for extrudably deforming tubes (12) into conformity with a flange (16) has a plurality of first and second forming members (28,30) circumferentially arranged on a mandrel (20). In an initial position, the forming members (28,30) are axially offset and radially retracted for ease of insertion into the bore (13) of the tube (12). After insertion, the mandrel (20) is partially withdrawn by an actuator (64) and by such action, the forming members (28,30) are brought together in an abutting, axially aligned, and radially expanded relationship such that workpiece-contacting surfaces (40,42) of the forming members (28,30) are brought into substantially continuous circumferential contact with the tube bore 13. The workpiece-contacting surfaces (40,42) are maintained in continuous circumferential contact with the tube bore 13 as the forming members (28,30) and the mandrel (20) are withdrawn from the tube end, thereby uniformly extruding the tube.
