摘要： A linkage arrangement for an active anti-tip system is provided for improving the stability of a powered vehicle, such as a powered wheelchair. The vehicle includes a drive-train assembly which is pivotally mounted to a main structural frame. A suspension system biases the drive-train assembly and its connected anti-tip wheel to a predetermined resting position. The drive-train assembly bi-directionally rotates about a pivot in response to torque applied to or acceleration forces on the vehicle. The linkage arrangement is characterized by a suspension arm pivotally mounting to the main structural frame about a pivot at one end thereof and an anti-tip wheel at the other end. The linkage further includes at least one link operable to transfer the bi-directional displacement of the drive-train assembly to the suspension arm and may also include a bell crank link member.

摘要： An anti-tip system is provided for stabilizing a vehicle, such as a power wheelchair, about a pitch axis and relative to a ground plane. The anti-tip system includes at least one anti-tip wheel. The mounting assembly for the anti-tip wheel is configured such that it traverses linearly in a direction toward or away from the ground plane and is responsive to an acceleration or deceleration of the wheelchair. As the wheelchair accelerates or decelerates, rotational motion of the drive train assembly is transmitted to a guide subassembly within the mounting to effect translation of the anti-tip wheel. Upward translation of the anti-tip wheel enables the wheelchair to negotiate obstacles, e.g., curbs or steps, while downward translation or force enhances stability when stopping the wheelchair or while moving down sloping terrain or surfaces. The anti-tip wheels may be castors and normally contacting the ground during operation.
摘要翻译：提供了一种用于使车辆（例如电动轮椅）围绕俯仰轴线并相对于接地平面稳定的防倾斜系统。防顶系统包括至少一个反头轮。用于反尖端轮的安装组件被构造成使得其在朝向或远离接地平面的方向上线性地横穿，并且响应于轮椅的加速或减速。当轮椅加速或减速时，传动系组件的旋转运动被传递到安装件内的引导子组件以实现反头轮的平移。反向轮的向上平移使得轮椅可以协商障碍物，例如路缘石或台阶，而向下的平移或力可以在停止轮椅时或同时向下倾斜的地形或表面的同时提高稳定性。反头轮可以是脚轮，并且在操作期间通常接触地面。
