초록 ▼

A four wheel drive vehicle suitable for use as a wheelchair or the like. The vehicle has a steering arrangement which allows the vehicle to be steered merely by selectively driving the left and right wheels. The steering arrangement requires at least one of the front and rear pairs of wheels to be castor mounted so as to be freely pivotal around respective pivot pins, with the pair of castor mounted wheels being linked so that they pivot generally in unison. Preferably, each of the castor mounted wheels rotate in a vertical plane which is laterally spaced from the pivot pins.

대표청구항 ▼

A wheelchair comprising: a frame, with a pair of front wheels and a pair of rear wheels movably supporting the frame, and a seat and a footrest mounted on the frame; a motor drivably connected to each wheel for rotating that wheel in its vertical plane; a steering means wherein at least the front pair of wheels is castor mounted on the frame so that each wheel freely pivots about a respective vertical axis, the steering means further comprising a linkage means connecting the pair of castor mounted wheels so that the castor mounted wheels pivot generally in unison, and control means to control power to be independently delivered to each of the wheels to steer the wheelchair; and wherein the frame comprises a slender, longitudinally extending intermediate portion with front and rear end portions at respective opposite ends thereof, the front and rear pairs of wheels being mounted to the front and rear end portions respectively; wherein the footrest is mounted to the front end portion of the frame, is positioned between a forward portion of each of the front pair of wheels, and has a width which is greater than that of the intermediate portion of the frame which is positioned between a rearward portion of each of the front pair of wheels; and wherein each one of the castor mounted front wheels has a positive trail with a horizontal axis about which the wheel rotates, being spaced from and on a rearward side of the vertical pivotal axis about which it pivots so as to maximize the pivotal movement of the front wheels while not allowing the wheels to interfere with the footrest or the frame.
