摘要:
A computer implemented method, computer program product, and data processing system for reducing the number of inner classes in a compiled computer program written in an object-oriented programming language. An outer class of the compiled computer program is received, wherein the outer class contains an inner class, wherein the outer class comprises instructions to create an instance of an inner class. The instance is to be used as one of a callback, a listener command, a set of instructions by which an object instance of the inner class transfers information to the corresponding containing instance of the outer class, and combinations thereof. A transformation of the outer class is performed by moving methods of the inner class, as well as their contained instructions, into the outer class. The behavior of the compiled computer program remains unchanged.

The present invention provides a shuttle valve for a multipath hydraulic circuit comprising a valve body having a main passage extending along an axis and having a uniform inner periphery. The shuttle valve further has a slider valve positioned within the main passage which has a first section adjacent and attached to a second section. The first section has a first outer periphery substantially similar to the inner periphery of the main passage such that the first section of the slider valve and the main passage substantially prevent fluid flow therebetween. The first outer periphery extends a predetermined length which is shorter than the intersection length. The second section has a second outer periphery with a recessed portion being recessed from the outer periphery of the main passage such that fluid is able to pass between the second section and the inner periphery of the main passage. As a result, fluid is able to pass from the first passage and around the slider valve and to the second passage or the third passage.

An overrunning clutch assembly for an automatic transmission having a plurality of planetary gear sets. The overrunning clutch assembly includes an inner race and an outer race. The outer race radially surround the inner race. The overrunning clutch assembly further includes a plurality of rollers disposed between the inner race and the outer race for permitting relative rotation between the inner race and the outer race in a first direction and limiting relative rotation between the inner race and the outer race in a second direction. The outer race includes a radially extending portion extending radially inward beyond an outer periphery of the inner race. The radially extending portion cooperates with the inner race to react a thrust load generated by the plurality of gear sets.

The present invention relates to a transmission for an automotive vehicle having a clutch retainer assembly or thrust bulkhead fixedly secured to the transmission housing and interdisposed between the reverse clutch assembly and the fourth clutch assembly. A pair of thrust bearing assemblies are interdisposed between the clutch assemblies and the thrust bulkhead to transfer the axial thrust loads generated by the multiple planetary gear assemblies through the thrust bulkhead to the transmission housing.

A piston is reciprocable in a cylinder of a valve body. A spring in the cylinder has one end bearing against the piston. An abutment holds a retainer in bearing engagement with the opposite end of the spring to hold the spring under compression. The valve body has a slot through which the retainer may be introduced transversely into the cylinder when the spring is further compressed. The retainer has a locking tab. The valve body has an axial notch extending from the slot in a direction away from the spring to clear the tab when the spring is further compressed by a tool and the retainer is introduced. When the tool is withdrawn and the retainer is forced back against the abutment by the spring, the tab extends beyond the notch to be overlain and trapped or blocked by a portion of the valve body to prevent the retainer from falling out of the cylinder through the slot.

A north-south transaxle includes a case having a first passageway extending longitudinally, a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally, and a cavity at one end of the second passageway having an opening generally perpendicular to the second passageway. The transaxle also includes a transmission assembly disposed in the first passageway, a transfer assembly disposed in the second passageway and a structure interconnecting the transmission assembly and transfer assembly for transferring torque from the transmission assembly to the transfer assembly. The transaxle further includes a differential assembly disposed in the cavity and the transaxle is structured to thermally compensate preload on the differential assembly over a temperature operating range.

A multi-speed hybrid transmission includes a main gearset connected to a vehicle gas combustible engine and providing torque to an output shaft. The transmission also includes an electric drive unit comprising an electric motor that is selectably connectable to the output shaft to provide additional torque to the output shaft. When connected to the output shaft, the electric drive unit improves vehicle performance under certain driving conditions (e.g., high boost in low gear or in upper gears) while also improving fuel efficiency.

A hydraulic control system for an automatic transmission includes a planetary gear system having a plurality of clutch elements that alters the torque ratio of the transmission. The hydraulic control system includes a line pressure control device for regulating a variable hydraulic line pressure from a maximum line pressure to a fixed fluid line pressure that is lower than the maximum line pressure when an overdrive clutch is applied in a high gear.
