US7273122(Hybrid hydraulic drive system with engine integrated hydraulic machine)

US7273122

動作可能：
1) "at least one fluid energy storage accumulator operable to store and release a pressurized fluid"

2) "a reversible hydraulic machine operatively coupled to an output shaft of said prime mover upstream of the transmission"

3) "The hybrid hydraulic (or regenerative) drive system 8 is operable in three modes of operation including a retarding mode, a driving mode and a neutral mode."

分詞：
"said reversible hydraulic machine being in fluid communication with said at least one energy storage accumulator; and said hybrid hydraulic drive system being arranged such that in said retarding mode said reversible hydraulic machine retards the drive wheels of the vehicle by pumping fluid into said at least one energy storage accumulator"

構成、適合：
"said hybrid hydraulic drive system thereby in use being adapted to supply said supplementary regenerative power and retardation to said drive wheels substantially independently of said prime mover."

設ける：
"a clutch assembly provided for selectively coupling said reversible hydraulic machine to said prime mover"

代名詞：
"wherein said reversible hydraulic machine is operatively coupled to said output shaft of said prime mover at a rear end thereof."

駆動接続：
1) "said torque converter includes a turbine drivingly connected to said output shaft of said prime mover"

2) "Preferably, the transmission 12 is a planetary automatic transmission including a hydrodynamic torque converter 14 that drivingly couples the prime mover 10 to the transmission 12."

可能：
"wherein said reversible hydraulic machine is a reversible hydraulic pump/motor unit capable to function both as a hydraulic pump and a hydraulic motor."

使う、使われる：
"The use of the energy in the known systems is therefore somewhat inefficient and the known systems therefore have not met with widespread use."

損ねる、低減する：
"However, the additional cost, complexity and weight of such multi-speed designs detract from the feasibility of multi-speed designs."

仮定法：
"In these cases the mounting system would need to support not only the pump/motor unit, but also the gearbox. This required structure will often present a challenge in and of itself to design, and fit into the vehicle chassis. An in depth analysis of the chassis dynamics, weight distribution, noise, harshness, vibration, and critical operational clearances would be required before any such structure could be designed."

示す、表す：
"FIG. 1 schematically depicts a hybrid hydraulic (or regenerative) drive system 8 in accordance with a first embodiment of the present invention for application in motor vehicles, especially heavy land vehicles, such as trucks and buses."

分かる、理解されるであろう：
"It will be appreciated that any appropriate type of vehicular transmission is within the scope of the present invention."

流体接続：
"at least one high-pressure hydraulic accumulator 36 fluidly connected to the hydraulic machine 32."

独立して：
"With this arrangement, the displacement of the integrated hydraulic pump/motor unit 32 may be varied and thus the pressurized hydraulic fluid flow produced can be controlled independent of speed at which it is driven."

という意味で、点で：
"Such an arrangement is called in the art a "live" PTO in that it is directly connected to the engine and power can be taken (or given) to the engine through it regardless of transmission operation."

収容：
"The first chamber carries a charge of compressible nitrogen gas, while the second chamber is arranged by suitable valve means to receive and release therefrom, a substantially incompressible hydraulic fluid, such as oil."

therewithin:
"The accumulators 11 accumulate energy by increasing the amount of oil stored within the second chamber so that the movable piston is caused to move to reduce the volume of the first chamber and so compress the gas stored therewithin."

の場合：
"In use, this valve would relive any accumulator pressure when the vehicle is shut down or in the event of a system malfunction."

倒置：
"Along with the reduction in the required displacement of t the engine integrated hydraulic pump/motor unit, comes a reduction in weight."

実現：
"In those circumstances where the engine integrated hybrid hydraulic system is operational over a wider vehicle operational speed range, the resulting greater utilization of the hybrid system generally results in an increased hybrid system performance realization."

ある：
"Engine Starting: with the hydraulic pump/motor unit connected to the vehicle engine, there exists the ability to use the pump/motor to start the engine."

もたらす、供給、得られる：
"the engine driven hydraulic pump/motor unit provides for the possibility of the generating auxiliary hydraulic power."
