Title:
トレーラ用の再生駆動システム
Document Type and Number:
Japanese Patent JP2005538888
Kind Code:
A
Abstract:
A regenerative energy management system ( 1 ) adapted for use with a compound vehicle including a prime mover, drive train and a trailer ( 2 ) including independent wheels ( 3 ) isolated from the prime mover drive train. The system ( 1 ) includes energy accumulation means ( 5 ) operable selectively to store and release energy through controlled receipt and release of pressurised hydraulic fluid; a positive displacement hydraulic pump/motor assembly (8) in fluid communication with the energy accumulation means ( 5 ); and a low-pressure hydraulic reservoir ( 9 ) in fluid communication with pump/motor assembly. The pump/motor assembly ( 8 ) has a drive shaft for connection to at least one of the wheels ( 3 ). In a braking mode, the assembly ( 8 ) retards the associated wheel ( 3 ) by pumping hydraulic fluid into the accumulation means ( 5 ) while in a driving mode, it supplies supplementary power using hydraulic fluid from the accumulation means ( 5 ) and in a neutral mode, it exerts no substantial driving or retarding influence on the wheel ( 3 ).
