An international track wheelchair (ITWC) with a center of gravity directional controller (COGDC) is described in this paper. The rules for international track competition disallow devices designed solely for steering. Equipment has been disqualified for having steering handles, crown compensators, and other lever systems. However, the rules do allow tie-rod linkage and the use of springs for dampening caster flutter. The chair described in this paper exploits the physical properties of wheeled vehicles to achieve directional control on the track. This controller is effective, because turning is only required in one direction. Three such track wheelchairs have been developed and were used at the Paralympics in Seoul, Korea, in October of 1988.
本文介绍了一种带有重心方向控制器（COGDC）的国际田径轮椅（ITWC）。国际田径比赛规则禁止使用仅用于转向的装置。带有转向手柄、冠状补偿器和其他杠杆系统的设备已被取消资格。然而，规则允许使用拉杆联动装置以及使用弹簧来抑制脚轮颤动。本文所描述的轮椅利用轮式车辆的物理特性在跑道上实现方向控制。该控制器很有效，因为仅需在一个方向上进行转向。已经研发出了三款这样的田径轮椅，并于1988年10月在韩国首尔的残奥会上使用。
