摘要： A curb-climbing rear wheel drive power wheelchair is disclosed having a pair of drive wheels, at least one ground-engaging idler wheel connected to the frame forward of the drive wheels and at least one anti-tip wheel mounted above ground aft of the drive wheels. The drive wheels and anti-tip wheels are mounted on common suspension arms, pivoted to the frame of the wheelchair behind the drive wheels and resiliently suspended, so that the anti-tip wheels move up and down in response to movements of the drive wheel suspension.

摘要： A suspension system for mounting a pair of wheels to a wheelchair is disclosed. The system includes a crossbar pivotally mounted to the wheelchair so as to pivot about a longitudinal axis. At least one spring assembly is located between the crossbar and the wheelchair frame for controlling the pivoting of the crossbar. A hinge assembly is mounted on each lateral end of the crossbar. The hinge assembly includes a first hinge component attached to the crossbar so as to be rotatable about a vertical axis, and a second hinge component resiliently connected to the first hinge component. The resilient connection biases the second hinge connection against rotation with respect to the first hinge component. A wheel and yoke assembly are mounted to the second hinge component.

摘要： A curb-climbing rear wheel drive power wheelchair is disclosed having a pair of drive wheels, at least one ground-engaging idler wheel connected to the frame forward of the drive wheels and at least one anti-tip wheel mounted above ground aft of the drive wheels. Each drive wheel and an associated drive assembly are mounted to a motor support bracket that is pivoted to the frame of the wheelchair. The drive assembly is mounted such that its motor is angled upward and rearward from the bracket. The anti-tip wheel is attached to one motor support bracket such that pivoting of the motor support bracket causes vertical displacement of the anti-tip wheel.

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： A bi-directional anti-tip system for a wheelchair includes a pair of anti-tip system subassemblies actively lifting a leading anti-tip wheel when traveling in either forward or reverse directions. The anti-tip system subassemblies operate to couple a leading anti-tip wheel to the drive assembly such that pivot motion thereof effects vertical displacement of the leading anti-tip wheel and to decouple a trailing anti-tip wheel from the drive assembly to null pivot motion inputs therefrom. In one embodiment, rheonetic links actively couple and decouple the anti-tip system subassemblies. The system may also include compliant bearings or extensible links for inward displacement of the anti-tip wheel upon impact with a curb.
摘要翻译：用于轮椅的双向防倾斜系统包括一对反尖端系统子组件，其在向前或向后行进时主动地提升前导的反尖端轮。反尖端系统子组件用于将前导的反尖端轮联接到驱动组件，使得其枢轴运动实现前导反头轮的垂直位移并且使拖尾的反头轮与驱动组件分离成零枢轴运动输入。在一个实施例中，流变连杆主动地联接和分离反尖端系统子组件。该系统还可以包括柔性轴承或可伸缩连杆，用于在与路缘石撞击时使反头轮向内移动。

摘要： A wheelchair according to one embodiment includes a frame, a pair of drive wheels operatively coupled to the frame, a drive operatively coupled to each drive wheel, and a pair of anti-tip assemblies. Each anti-tip assembly includes a first member, a second member pivotally coupled to the first member at a joint that defines a pivot axis, an anti-tip wheel rotatably coupled to the second member, and a locking mechanism. The second member is capable of pivoting about the pivot axis between an extended position and a collapsed position. The locking mechanism is configured to selectively lock the second member in the extended position.
