ABSTRACT:
The invention relates to a device used for driving the endless track of an earthworking machine or implement comprising a main drive sprocket provided with a plurality of teeth, which cooperate with a pinion whose outer teeth have a shape corresponding to that of the driving fingers of the endless, the said main drive sprocket being, on the one hand, mounted for rotation on a support secured to the chassis of the machine, and on the other hand, coupled to an hydraulic motor which drives it in rotation and is mounted on the said support, via the said pinion, which is wedged on the output shaft of the said hydraulic motor. The support which is common to the main drive sprocket, to its driving pinion and to the hydraulic motor has a vertical plane of symmetry which merges with the plane of symmetry common to the main drive sprocket and to its driving pinion. The invention finds an application in hydraulic shovels with caterpillar tracks.
