Transmisijos su hidrostatine pavara teoriniai tyrimai

Abstract

Darbe nagrinėjamas vienas mobilios ratinės transporto priemonės, eksploatuojamos esant blogam pravažumui, ratų buksavimo sumažinimo uždavinys. Tam tikslui transmisijoje panaudota hidrostatinė pavara, dalį variklio sukurto sukimo momento perduodanti pagalbiniams ratams per pagrindinio varančiojo tilto diferencialą. Pasinaudojant sudarytu transmisijos matematiniu modeliu, ištirtos jos pagrindinės savybės ir nustatytos hidrostatinės pavaros pagrindinių parametrų vertės, kurioms esant sukimo momentas transporto priemonės ratams paskirstomas geriausiai

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
