Four wheel drive, four wheel steering vehicle
First Claim
1. A vehicle principally for use in rugged terrain, comprising at least one beam or frame (6, 7) extending centrally in the vehicle'"'"'s longitudinal direction, where the beam or frame (6, 7) is provided with a first and a second rotatable device (3, 5), each of which devices (3, 5) can rotate about an axis perpendicular to the vehicle'"'"'s longitudinal axis (16), and that at least one of the rotatable devices (3, 5) is rotatably mounted relative to the beam or frame (6, 7) about the vehicle'"'"'s longitudinal axis (16) and that on each of the rotatable devices (3, 5) there are mounted rigid differential axles (2, 4), the differential axles (2, 4) are provided with synchronised drive devices (23) driven by a power source and the vehicle is provided with one or more steering synchronizing devices which rotate the differential axles (2, 4) on the rotatable devices (3, 5) in a relatively opposing relationship, and that the vehicle is provided with a steering device (13, 9) for steering the vehicle, characterized in that the synchronised drive devices (23) are T-drives aligned longitudinally with an interconnecting axle (24) and above a center of said rotatable devices.

Abstract
The present invention relates to a four-wheel drive vehicle which on account of its constructive composition has very good off-road characteristics, in addition to which the vehicle can be adapted to a number of transport requirements and can act as a tool carrier. The vehicle is substantially frameless in the traditional sense with a front and rear rigid differential axle mounted on a beam or frame extending centrally in the vehicle'"'"'s longitudinal direction, where at least one of the axles can rotate about the vehicle'"'"'s longitudinal axis, while at the same time both of the vehicle'"'"'s axles are each steered in the opposite direction to each other about their axes perpendicularly to the vehicle'"'"'s longitudinal axis.
