A hydraulic mechanism for driving a vehicle, and having right and left laterally spaced hydraulic motors which drive respective ground engaging wheels, an axle structure extending laterally between the right and left hydraulic motors for receiving operating loads from the ground engaging wheels, the right and left hydraulic motors being coupled with the axle structure for generally enclosing and sealing the axle structure, said generally sealed axle structure being adapted for containing hydraulic fluid and serving as a fluid reservoir, a hydraulic pump which drives the hydraulic motors, said pump being in operative fluid communication with the interior of the axle structure for drawing fluid therefrom, the pump being positioned outside the axle structure. The motors include input and output ports which are positioned within the axle structure, and hydraulic lines extend between the pump and the input and output ports. Portions of said hydraulic lines extend within the interior of the axle structure, and the interior lines include rigid and non-rigid lines which facilitate assembly and disassembly of the mechanism.
Mécanisme hydraulique pour propulser un véhicule comportant deux moteurs hydrauliques entraînant les roues gauche et droite montées aux extrémités d'un essieu conçu pour supporter les charges transmises par les roues motrices en contact avec le sol; les moteurs hydrauliques gauche et droit sont couplés à l'essieu de manière à former une structure à enveloppe hermétique destinée à contenir le fluide hydraulique et servir de réservoir; une pompe hydraulique montée à l'extérieur de l'essieu et en communication avec l'intérieur de l'essieu pompe le fluide hydraulique utilisé pour entraîner les moteurs hydrauliques. Les moteurs comportent des orifices d'entrée et de sortie qui sont situés à l'intérieur de l'essieu et reliés à la pompe par des canalisations hydrauliques. Certaines sections des canalisations hydrauliques sont disposées à l'intérieur de l'essieu; les canalisations hydrauliques disposées à l'intérieur de l'essieu comportent des sections rigides et des sections flexibles destinées à en faciliter le montage et le démontage.
