摘要： A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction.

摘要： A personal mobility vehicle includes an base unit having a frame and front and rear pivot arms pivotally mounted at respective front and rear pivot points. The front and rear pivot arms support casters. A drive unit having a ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. The base unit may also include a drive unit that is pivotally supported on the base unit by a torque arm and a suspension system that includes a suspension stop. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed.

摘要： A personal mobility vehicle includes a power-driven base unit that supports a suspension system. The suspension system includes a front suspension arm that supports a front caster wheel and includes a suspension stop. A drive unit is pivotally supported on the base unit by a torque arm. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed.
