摘要： Motor vehicles are equipped with a center-closed power steering system to provide power steering assistance in engine-off conditions for reduced fuel consumption. The power steering system includes a hydraulic pump mechanically driven by the engine, a high pressure accumulator, a steering gearbox fluidly connected to the accumulator, and a center closed valve mechanically connected to a driver-operated steering wheel. The valve is configured to selectively control flow of pressurized fluid from the accumulator to the steering gearbox to provide power steering assistance.

摘要： A variable displacement engine comprises two engine modules fed from a common fuel source, each engine module having an individual crankshaft. The first engine module has a high compression ratio (e.g., greater than 13:1), while the second module has a typical compression ratio for a gasoline engine (e.g., between 9:1 and 11:1). In one embodiment, the first engine module operates through high efficiency optimized alcohol fuel combustion when the fuel content exceeds a minimum alcohol content. In an alternative embodiment, the first engine module operates at high efficiency through gasoline HCCI combustion when conditions permit. When operating conditions do not permit the first engine module to operate at high efficiency, the second engine module operates as the primary engine module, with the first engine module available to provide supplemental power (at less than optimal efficiency) if needed to meet driver demand.

摘要： Embodiments for retaining the spherical ball of a piston connecting rod within a socket in a bore in a drive plate of a bent-axis pump/motor comprise swaging material at the periphery of the socket cavity toward the ball, to an outer diameter such that the swaged region is fully supported against pullout by the cylindrical wall of the bore. Alternatively, a retention ring which is fully supported by the walls of the cylindrical bore retains the ball within the socket and is in turn retained by a snap ring extending into a groove within the bore.

摘要： A method for operating a hybrid vehicle is provided, in which an engine generates secondary power that is either stored or used as direct input energy by a secondary power source to provide motive power to the vehicle. The secondary power source is powered by secondary energy from an energy storage device, direct input energy generated by the engine, or both, depending on the amount of stored secondary energy in combination with vehicle speed. When in use, the power level at which the engine is operated is also determined on the basis of available stored energy and vehicle speed. At higher vehicle speeds, the amount of stored energy is allowed to be depleted in order to increase the available storage capacity for regenerative braking.

摘要： A drive module for a hydraulic hybrid vehicle includes two variable displacement over-center bent-axis hydraulic pump/motors with respective yokes that reside and pivot within a common fluid-filled case. The cylinder barrel of each pump/motor is connected to high pressure through fluid-conducting yoke legs, and is connected to low pressure through the fluid-filled case, which is connected by a port to a low pressure source. As a drivetrain for a vehicle, one pump/motor acts primarily as a pump driven by an engine and the other pump/motor acts primarily as a motor to propel the vehicle. A removable support structure facilitates installation to a variety of vehicle chassis.

摘要： A piston-in-sleeve accumulator includes a cleaning element positioned on the piston and configured to remove and prevent debris from lodging between the piston and a cylindrical nonpermeable sleeve within which the piston slides. A seal on the piston is positioned to engage an opposing surface in the event of a leak, and thereby prevent the possibility of a complete drainage of pressurized fluid from occurring through the accumulator's fluid port. A position contactor switch is further provided to signal position of the piston within the accumulator.

摘要： A rotating group of a bent-axis axial piston pump/motor is assembled as a subassembly with a removable stabilizing component that holds together and compresses the subassembly while it is outside of the pump/motor case. A yoke that carries a permanent or attachable back plate is installed in the case and positioned aside to allow clearance for installation of the rotating group. After the rotating group is installed, the yoke is moved back into proximity with the barrel, the stabilizing component is removed, and the remaining connections are completed.

摘要： A vehicle includes an internal combustion engine configured to power a hydraulic pump to pressurize hydraulic fluid, which is used to power the vehicle directly or is stored in an accumulator. A drive module, including a hydraulic pump/motor and a multi-speed mechanical transmission, is operatively coupled to drive wheels of the vehicle to provide motive power to the vehicle. The drive module can also include a second hydraulic motor (or multiple hydraulic motors) configured to provide motive power. The transmission is configured to progress through its gears at ratio shifts of no less than 2:1 between adjacent gear positions. The transmission is configured to place the hydraulic motor in neutral during some portions of vehicle operation, and to engage the motor during other portions of vehicle operation.

摘要： A hydraulic manifold has features adapted to the needs of hybrid vehicle applications. In one embodiment, multifunction valves selectively regulate fluid flow among primary and auxiliary flow paths. A normally closed butterfly valve is biased by a relatively small secondary biasing force against rotation in first and second (opposite) directions, and by a relatively large principal biasing force against rotation in the first direction past a transitional angular position at which the principal biasing force takes effect. An actuator selectively controls the transitional angular position and the magnitude of the principal biasing force. In the first direction, flow must overcome only the secondary biasing force to pass the valve. In the second direction, any flow sufficient to overcome the secondary biasing force but not the principal biasing force will divide into a first flow passing the valve and a second flow induced to enter an auxiliary path upstream. Additional flow causing the principal biasing force to additionally be overcome will substantially pass the valve as part of the first flow. This and other embodiments provide a manifold that is controllable to allocate flow among primary and auxiliary paths while remaining responsive to sudden large changes in flow independently of immediate control response.
摘要翻译：液压歧管具有适合于混合动力车辆应用的需要的特征。在一个实施例中，多功能阀选择性地调节主要和辅助流动路径之间的流体流动。常闭蝶阀通过相对较小的次级偏压力被抵抗第一和第二（相反）方向上的旋转，并且通过相对较大的主偏压力抵抗第一方向上的旋转超过过渡角位置，在该过渡角位置处，主偏压力生效。致动器选择性地控制过渡角位置和主偏置力的大小。在第一个方向上，流动只能克服二次偏压力来通过阀门。在第二方向上，足以克服二次偏压力而不是主要偏压力的任何流动将分成通过阀的第一流和被引导进入辅助通道上游的第二流。另外克服主要偏压力的额外流动将基本上通过作为第一流动的一部分的阀。本实施例和其它实施例提供了可控制的歧管，以在主路径和辅助路径之间分配流量，同时保持响应于独立于即时控制响应的突然的大流量变化。

摘要： A hydraulic brake system includes a piston that separates a first pressure chamber from a second pressure chamber of a cylinder bore. A valve within a piston bore is movable between three positions. In the first position, the first and second pressure chambers are in fluid communication with a low-pressure fluid supply; in the second position, the second pressure chamber is isolated from the first pressure chamber and the low-pressure fluid supply; in the third position, a high-pressure fluid supply is in fluid communication with the second pressure chamber, allowing high-pressure fluid to flow into the second pressure chamber. High pressure in the second pressure chamber moves the boost piston, applying boosted braking pressure to a vehicle brake. Pressure in the second chamber against a surface of the valve biases the valve toward the first position. An accumulator stores pressurized fluid and provides the high-pressure fluid supply, enabling on-demand brake boosting force during engine-off operation of a hybrid vehicle.
