Abstract
A drive apparatus for driving front and rear wheels of a motor vehicle, either the front and rear wheels being mechanically driven, through a power transmission mechanism, by a motive power generated by an engine of the motor vehicle and the other wheels being driven by hydraulic motors rotationally driven by a hydraulic pump. The drive apparatus limits driving forces of the other wheels, rotationally driven by the hydraulic motor, to be below a predetermined driving force and further detects occurrences of acceleration slips of the one wheels, rotationally driven through the power transmission mechanism, on the basis of speeds of the other wheels in which the driving force is limited to be below the predetermined driving force. The driving forces of the one wheels are adjusted in accordance with the acceleration slip detection result so as to suppress the occurrences of the acceleration slips. This arrangement can improve the travelling stability of the motor vehicle and the motive power on a low friction coefficient road surface without requiring a complex structure.
