There is disclosed an all-terrain vehicle having a front and a rear body frame connected by an articulated joint for allowing relative lateral oscillation of the frames about an oscillation axis parallel to the longitudinal axis of the front body frame and located above both frames. The joint simultaneously allows for relative pivoting movement of the frames about a pivot axis which is perpendicular to the oscillation axis. The vehicle is driven by four pressure-fluid operated motor assemblies of which the motor output shafts are coaxial two-by-two and are mounted to extend laterally outwardly of the frames and on which shafts are operatively mounted endless track assemblies for winter use, particularly, or pneumatic tires. The motors are fed in pressure-fluid by piping connected to pumps actuated by an engine mounted on the front body frame. At least that part of the piping that traverses the body frames, at the articulated joint, is flexible.

An all-terrain vehicle comprising: a front vehicle body including a generally flat body frame having a longitudinal axis; a rear vehicle body including a generally flat body frame having a longitudinal axis; an articulated joint connecting said body frames together for allowing relative lateral oscillation of said frames about a roll axis parallel to the longitudinal axis of one of said body frames, said roll axis being located above both of said frames; said joint further allowing pivotal movement of said frames about a steer axis perpendicular to said roll axis; said articulated joint comprising; (1) a first articulation member and means mounting said first member on one of said body frames for relative oscillation of said first member and of said one of said body frames about said roll axis; (2) a second articulation member solid with the other of said body frames; and (3) means joining said two articulation members together, said means being constructed to allow said relative oscillation and said pivotal movement of said body frames; four motor assemblies each including a pressure-fluid operated motor having an output shaft; means mounting two of said motor assemblies on said front body frame with the output shafts thereof being coaxial and extending laterally outwardly of said front body frame; means mounting the remaining two motor assemblies on said rear body frame with the output shafts thereof being coaxial and extending laterally outwardly of said rear body frame; pressure fluid generating means on one of said body frames, said generating means including fluid piping operatively connected to said motors to supply pressure fluid thereto for rotating said shafts; wherein a portion of said piping extends between said body frames and is flexible for easing said relative lateral oscillation and said pivotal movement of said body frames; and four ground-engageable traction means, each connected to one of said output shafts for propelling said vehicle over the ground.
