Abstract
The present invention relates to an apparatus providing for the co-ordinated driving of a towing vehicle and a towed vehicle equipped with a hydrostatic driving system of its own. The respective driving wheels of the towed vehicle are each driven by a separate hydrostatic transmission and a variable output hydraulic pump coupled to a hydraulic motor which can be driven by output of said hydraulic pump and can be engaged with a driving wheel. The apparatus includes for each respective transmission control circuits having a control device mounted on the towing vehicle. The invention is particularly useful for a cross-country towing vehicle and a towed vehicle in the form of a heavy field artillery gun which for purposes of operating the hydrostatic transmissions is equipped with a reciprocating engine, for instance a gasoline engine, which actuates said transmissions via a dividing gear box.
