    Abstract: A hydraulic power assist rack and pinion steering system (12) for a vehicle includes a housing (14) in which a rack (10) is movable along an axis (16) to effect turning movement of steerable wheels of the vehicle. The rack (10) comprises a first rack part (50) having an elongate body portion (56) and an end portion formed as a first piston portion (58), and a second rack (80) part having an elongate body portion (86) and an end portion formed as a second piston portion (88). The first piston portion (58) of the first rack part (50) is joined to the second piston portion (88) of the second rack part (80) to form a piston (22). The body portion (56) of the first rack part (50) extends axially away from the piston (22) in a first direction (110). The body portion (86) of the second rack part (80) extends axially away from the piston (22) in a second direction (112) opposite the first direction (110).

    Abstract translation: 用于车辆的液压动力辅助齿条和小齿轮转向系统(12)包括壳体(14),其中齿条(10)可沿着轴线(16)移动,以实现车辆的可转向车轮的转动。 齿条(10)包括具有细长主体部分(56)和形成为第一活塞部分(58)的端部的第一齿条部分(50)和具有细长主体部分(86)的第二齿条 )和形成为第二活塞部(88)的端部。 第一齿条部(50)的第一活塞部(58)与第二齿条部(80)的第二活塞部(88)接合,形成活塞(22)。 第一齿条部分(50)的主体部分(56)在第一方向(110)上沿着轴向远离活塞(22)延伸。 第二齿条部分(80)的主体部分(86)沿与第一方向(110)相对的第二方向(112)轴向地远离活塞(22)延伸。
