Patent

CA 2233571

The invention discloses a steering device for a pair of wheels, in which both wheels are turnable more than 180~ and where the turning points of the wheels (10) substantially coincide. The invention comprises a two part tie rod (16) with a turnable joint (18), the outer ends of said tie rod (16) each are turnably connected to two arms (20, 28). The first arm (20) is attached to the axis of the wheel (10) by a rigid wheel plate (26), and the second arm (28) is attached to the wheel beam (12). By conveying the joint (18) of the tie rod by assistance of a joint track means (32, 34, 36, 38) along a predetermined track, the wheels (10) are turned according to the principle of coinciding turning points. The attachment to the first and second arms (20, 28) also enables a wheel turning of more than 180~.

Dispositif de direction pour une paire de roues, grâce auquel les roues peuvent tourner selon un angle de plus de 180·, et les centres de braquage des roues (10) sont sensiblement coïncidents. Le dispositif comporte un tirant en deux parties (16) possédant une articulation pivotante (18), chacune des extrémités extérieures dudit tirant (16) étant reliée à pivotement à l'un des deux bras (20, 28). Le premier bras (20) est relié à l'axe de la roue (10) par l'intermédiaire d'une plaque de roue rigide (26), et le second bras (28) est fixé à l'essieu (12). L'articulation (18) du tirant est déplacée à l'aide de moyens de guidage (32, 34, 36, 38) dans une ouverture de guidage déterminée, de manière que les roues (10) tournent conformément au principe des centres de braquage coïncidents. La fixation aux premier et second bras (20, 28) permet également à chaque roue de tourner selon un angle de plus de 180·.
