摘要：
A vehicle such as a riding lawn care vehicle may include a frame and a steering assembly. Wheels of the vehicle may be attachable to the frame. The steering assembly may include a steering apparatus operably coupled to at least one of the wheels of the vehicle to provide steering inputs to the at least one of the wheels based on a position of the steering apparatus. The steering assembly may further include a steering column, a pinion assembly and a rack assembly. The steering column may extend from the steering apparatus to rotate responsive to movement of the steering apparatus. The pinion assembly may be disposed along the steering column and include at least two pinions of different sizes. The rack assembly may be operably coupled to the frame and the at least one wheel of the vehicle to translate steering inputs from the steering apparatus to the at least one wheel via the pinion assembly. The rack assembly may include at least two rack portions of different sizes.
摘要（中）：
诸如骑马草坪护理车辆的车辆可以包括框架和转向组件。 车辆的车轮可以附接到车架上。 转向组件可以包括可操作地联接到车辆的至少一个车轮的转向装置，以基于转向装置的位置向至少一个车轮提供转向输入。 转向组件还可以包括转向柱，小齿轮组件和齿条组件。 转向柱可以从转向装置延伸，以响应于转向装置的运动而旋转。 小齿轮组件可以沿着转向柱布置并且包括至少两个不同尺寸的小齿轮。 齿条组件可以可操作地联接到框架和车辆的至少一个车轮，以经由小齿轮组件将来自转向装置的转向输入转换成至少一个车轮。 齿条组件可以包括至少两个不同尺寸的齿条部分。
