Pinion Valve Assembly
Item Name / Component • Input Shaft Function
与T/Bar通过Dowel pin 固定。 将Column的Torque传递给T/Bar和P/Shaft。 根据Edge的形状决定特性(操纵感)。 打开和关闭油路，控制工作油的流动。 油路槽使工作油的流动更加畅通。 O-Ring防止内部漏油(Leak)。 利用C-Type Stop Ring固定V/Body位置。 连接I/Shaft和P/Shaft。 形成扭角。 形成回复力(Spring)。 利用O-Ring防止内部漏油(Leak)。
HYDRAULIC PARTS
1) RACK PISTON 维持Cylinder的左右油压，将作用于Cylinder截面的压力转换成移动RACK BAR的动力。 2) OIL SEAL 密封CYLINDER的左右，防止漏油。 3) RACK BUSH RACK BAR移动时起到GUIDE作用，同时有密封作用，维持Cylinder的内部压力。 4) RACK STOPPER 防止Rack Bush的脱离，维持Rack Stroke。 5) FEED TUBE 连接VALVE和CYLINDER之间的油路。

MOUNTING BUSH
<转向装置的原理>
如图所示，当方向盘(Steering Wheel)和转向柱(STEERING SHAFT)旋转时，小齿轮(PINION)跟着旋转，
与齿轮(Pinion)啮合的齿条(Rack)做左右直线运动。这种直线运动通过推拉横拉杆(Tie Rod)传递到轮胎的枢
轴，轮胎 (Tire) 的转动则直接改变车的行驶方向。

<产品的结构/功能>
1. 转向装置相关
◆ 方向盘(Steering Wheel)
- 驾驶者向所需的方向旋转的把手(Handle)
◆ 转向柱(Steering Column) - 安装FUNCTION SWITCH等，还包括车辆碰撞时保护驾驶者的吸能(Energy Absorbing)功能，以及传递方向盘的旋转力。 ◆ UNIVERSAL JOINT - 在COLUMN和转向器(Gear Box)之间具有补偿相位角的功能，传递旋转力。 ◆ STEERING GEAR ◆ PUMP ◆ RESERVIOR - 将方向盘的旋转运动转换成直线运动，根据液压助力以及Steering Effort来决定。
-通过引擎驱动，向STEERING GEAR供应工作液压。 - 供应到PUMP之前的储油壶，过滤OIL的异物。
◆ PRESSURE HOSE
◆ RETURN TUBE ◆ 实车LINKAGE
- 从PUMP向STEERING GEAR输送高压工作油。
- 从STEERING GEAR向RESERVIOR输送低压工作油。

CONTROL VALVE PARTS
1) TORSION BAR : 连接到I/S和P/S，转动方向盘时引起I/S和V/BODY之 间相对变位，通过控制STIFFNESS可改变P/V特性曲线。 2) INPUT SHAFT : I/S上加工有ORIFICE EDGE，转动方向盘时，利用与 V/BODY之间的相对变位形成缸体内压力差。 3) VALVE BODY : 通过连接到P/S来固定，当RACK BAR直线运动时开始 旋转，与I/S之间的相对变位形成压力差。 4) PINION SHAFT : 抑制V/B旋转方向的变位，通过与RACK啮合将 方向盘的旋转运动转换成直线运动。 5) VALVE HOUSING 支撑各个组件，防止油的外漏。
