    • A die apparatus and method for performing a flashless forging operation to manufacture the toothed portion of a steering rack. The die apparatus comprising first and second die members and at least one punch member, each having a forming surface shaped substantially as the obverse of a portion of said toothed portion, and at least a portion of the forming surface of said first die member being shaped substantially as the obverse of the teeth of said rack. Said first and second die members being moveable towards each other to a closed position thereby partially forging said toothed portion from a blank placed in said die apparatus and forming a substantially closed cavity defined by said forming surfaces, said punch member being adapted to move into said cavity, once said die members are in said closed position, thereby completing said forging operation.
    • 一种用于执行无颤动锻造以制造转向齿条的齿形部分的模具设备和方法。 所述模具设备包括第一和第二模具构件和至少一个冲压构件,每个冲压构件具有基本上形成为所述齿形部分的一部分的正面的成形表面,并且所述第一模具构件的成形表面的至少一部分成形 基本上如所述齿条的齿的正面。 所述第一和第二模具构件能够彼此相对移动到关闭位置,从而部分地将所述齿形部分从位于所述模具装置中的坯件锻造并形成由所述成形表面限定的基本封闭的空腔,所述冲压构件适于移动到所述 一旦所述模具构件处于所述关闭位置,从而完成所述锻造操作。

    • A steering system for a vehicle comprising a steering gear (10) having a rack (12) and a pinion (14) in mesh therewith. The rack (12) being laterally displaceable with respect to the vehicle as a function of inputs from a steering wheel (24) through rotation of the pinion (14), and a steering superposition means (32). The steering system further comprising first and second road wheels (20a, 20b) steerable by rotation of first and second steering arms (21a, 21b) respectively by means of first and second tie rods (15a, 15b) arranged to transmit lateral displacement of the rack (12) to the first and second steering arms (21a, 21b) respectively. Lateral displacement of the rack (12) being transmitted to at least one of the steering arms (21a, 21b) through a linear actuator (25). The linear actuator (25) and the steering superposition means (32) being controlled by a control means (30) in response to at least one sensed parameter (31).
    • 一种用于车辆的转向系统,包括具有齿条(12)和与其啮合的小齿轮(14)的舵机(10)。 作为来自方向盘(24)通过小齿轮(14)的旋转的输入的函数,机架(12)可相对于车辆横向移位,以及转向叠加装置(32)。 所述转向系统还包括通过第一和第二牵引杆(15a,15b)分别通过第一和第二转向臂(21a,21b)的旋转而转向的第一和第二公路轮(20a,20b) 齿条(12)分别连接到第一和第二转向臂(21a,21b)。 齿条(12)的横向位移通过线性致动器(25)传递到至少一个转向臂(21a,21b)。 响应于至少一个感测到的参数(31),线性致动器(25)和转向叠加装置(32)由控制装置(30)控制。
