车辆滚动控制系统

Vehicle roll control system
Abstract:
A vehicle roll control system, comprising a front torsion bar(22), attached to the front hydraulic actuator (34) and a rear torsion bar (24) attached to the rear hydraulic actuator (34′). A pressure control valve (99) is fluidly connected between a pressure source (80) and a reservoir (81). A directional valve (82) is fluidly connected between the pressure control valve (99) and the hydraulic actuators (34,34′). A pressure relief valve (83,84) fluidly connects the directional valve to the pressure source (80) or the reservoir (81) and is actuated to create pressure differential between first fluid chambers (58,58′) of the hydraulic actuators (34,34′)and/or to create pressure differential between second fluid chambers (60,60′) of the hydraulic actuators (34,34′).
Abstract(Chinese):

一种车辆滚动控制系统，包括附接到前液压致动器（34）的前扭杆（22）和附接到后液压致动器（34'）的后扭杆（24）。 压力控制阀（99）流体地连接在压力源（80）和储存器（81）之间。 方向阀（82）流体连接在压力控制阀（99）和液压致动器（34,34'）之间。 减压阀（83,84）将方向阀流体地连接到压力源（80）或储存器（81），并被致动以在液压致动器（34）的第一流体室（58,58'）之间产生压力差 ，34'）和/或在液压致动器（34,34'）的第二流体室（60,60'）之间产生压力差。
