NOVELTY - A work machine has a front section with a front frame and a pair of front ground engaging members (135,235), and a rear section with a rear frame and two pairs of rear ground engaging members (136,137,236,237). Both sections are coupled together by a pivot joint. A power source (140), including an internal combustion engine (105) and an electric machine (142), is provided preferably in the front section. Electric motors (146,148,150,152) are provided preferably in the rear section and individually assigned to and driving rear ground engaging members. The engaging members are wheels.    USE - Work machine. Uses include but are not limited to e.g. articulated hauler (claimed) of hybrid electrical type for transport of large and heavy loads, wheel loaders, earth-moving machinery, off-road work machines, construction equipment, forest machines.    ADVANTAGE - The work machine can operate advantageously in severe terrain conditions, since the electric motors create conditions for infinitely variable torque distribution between rear ground engaging members. The motors also drive the rear ground engaging members individually in energy-efficient manner, eliminating mechanical transmission of power to same members as well as power train issues due to different turning radius, and allowing for adjustment of rotation speed of front ground engaging member axle in relation to rear ground engaging member axles during cornering leading to improved performance. Elimination of mechanical transmission also leads to lower parts count and permits machine to regenerate in over-run and braking conditions while reducing specific fuel consumption of machine. Kerb weight of machine is reduced, leading to lower service and production costs. Eliminating transmission shaft through pivot joint permits steering angle between front and rear sections to be increased when needed. Eliminating mechanical transmission also leaves lot of space for installation of energy storage devices e.g. batteries. Favorable weight distribution as well as positioning of some components e.g. internal combustion engine, creates conditions for more efficient packaging of power train components in front frame of machine. Elimination of gearbox and propeller shaft lowers operator position and decreases impact of body vibrations in fore-to-aft and sideways directions of operator. Torque can be infinitely variably supplied to rear ground engaging members to support front ground engaging member drive in slippery conditions. Length of nose of machine can be reduced, improving visibility from cab for operator especially when driving upwards on slope.
