    三十五年前，两个马自达设计师提出了个远见的、有计算认为是相当革命性的结论。
    他们在1902年1 0月26日日本汽车工程师学会技术会议上Tadashi 0 kada博士和
Toshiak，工程师总结了他们关于车辆动力学的辛勤研究如下:
    1.琴本特性差别在于过度转向与不足转向的和时间上的延迟和pn应
    2.汽车在局速状态卜应具备不足转向特点。
    3.后方的稳定很人程度上反映出车轮和轮胎口
    4.控制:稳定的一大进步，可预期的方式自动引导系统后车轮
    这种结论和提法被这两个工程师提出并为良好悬架技术的研制成立了华金会多年来致力于研究和开发，原有的理论有定的作用，些最重要的成就在近代历史上汽车底盘工程，将在马自达的系列产品的生产.这些发展包括双斜后方的联系巾断，首先采用原第一轮驱动323K(1980),马自达6X(1982},然后在更新完善马自达626.获奖的动态跟踪系统中断的第二代发票RC7(1985);并制定电了后方联系中断新马自达929(i987}.
    而与此同时各种外部压力和负荷作用，J汽车后方的车轮，因为它违背斗顿的运动
学原理，这些新系统中断将这些力量纳入”4ws效应’‘积极帮助稳定车辆和机敏。

Computerised 4-Wheel Steering System.Three and a half decades ago,well-calculated conclusion that presentation Conference,at the October 26,two young Mazda designers arrived at a far-sighted and was quite revolutionary for the time. In their technical 1962 Japanese Automotive Engineers' Society Technical Dr Tadashi Okada concerning vehicle dynamics as and engineer Toshiaki summarised their arduous research follows.
  1 The basic difference in the characteristics of oversteer and understeer lies in the
magnitude of time delay and response.
  2.a vehicle that is stable under high speed must possess understeer characteristics
  3.the rear wheel tyre reflects heavily on the stability and a major improvement on control and stability may be anticipated by means of the automatic rear wheel steering system.
  The conclusions and formulations presented by these two engineers established thefoundation for Mazda's present-day reputed suspension technology. Over years of dedicatedresearch and development expertise, their original discoveries and theories have contributed to some of the most significant achievements within the recent history of automotive chassis engineering, incorporated by Mazda within its series production products. These developments include the twin trapezoidal link rear suspension, first employed in the original front-wheel drive
  Mazda 323 (1980) and the Mazda 626 (1982}, and then perfected within the updated Mazd 626; the award winning Dynamic Tracking Suspension System of the second generation Mazda RX-7 (1985); and the elaborate E-link rear suspension of the new Mazda 929 (1987).
