Abstract

In the work a task of driving wheels’ towing reduction of a mobile vehicle, which is exploited in bad passing conditions, is investigated. For that purpose is used a transmission, when an engine-developed torque is transmitted to all driving vehicle’s wheels via the mean driving bridge’s differentials. For the auxiliary driving wheels’ transmission is used a hydrostatic system, made of constant operating volume hydraulic machines’. In the work is given a mathematical model of a hydraulic transmission’s of a mobile vehicle, being under analysis, basic properties of such a transmission have been investigated, constructional parameters’ values, in which torque’s distribution is realized so that the towing of driving wheels’ is minimum, have been detected. Also a hydraulic transmission’s power losses’ and influence of the properties’ of some supporting surfaces’ to kinematical indexes of compatibility have been analyzed.
