DIFFERENTIAL HYDROMECHANICAL VARIABLE-SPEED DRIVE

摘要

FIELD: mechanical engineering. ^ SUBSTANCE: variable-speed drive comprises two differential stages connected in series. The differential sage whose shaft is connected with the engine is the input shaft of the variable-speed drive and is made of a differential mechanism. The second differential stage is a hydraulic differential converter provided with two planet rows defined by the kinematical links of multi-gearing hydraulic pump and hydraulic motor provided with different gear ratios . The axles of the satellites of the first and second differential stages are mounted inside the housing . The housing is set in bearings inside the crankcase of the variable-speed drive and represents a carrier for both of the differential stages. The carrier is provided with the free running clutch. ^ EFFECT: enhanced efficiency. ^ 2 dwg
