CA 2347575
An articulated front axle assembly for an electric invalid power chair is provided. The assembly mainly includes a guide bar fixedly connected at an upper end to a lower end of a front direction-control handle of the electric invalid power chair and at a lower end to an n-shaped articulation member or a pivot shaft, and a front axle pivotally connected at a predetermined position to the articulation member or the pivot shaft. Two front guide wheels are separately connected to two ends of the front axle. The front axle is pivotally turnable relative to the guide bar in response to any unevenness, such as bumps and pits, and obstruction, such as a stair and a threshold, on a ground or a road, such that either of the two front guide wheels is able to always keep close contact with the ground or the road, and thereby provides increased side support force to the electric invalid power chair and prevents the same from tilting over while making a turn, allowing the electric invalid power chair to operate in a more stable and safer manner.
