HYDRO MECHANICAL DISPLACEMENT TRANSMISSION

摘要

FIELD: transport. ^ SUBSTANCE: proposed power transmission consists of drive and driven shafts, planetary mechanism, boxes of aligning gear and hydraulic circuit made up of two hydraulic machines integrated by hydraulic line with bypass valve fitted there between. One of said machines is made up of adjustable pump with drive engaged via driven shaft with rotation power source while another machine consists of hydraulic motor (adjustable or nonadjustable) whereto planetary mechanism is connected. Transmission incorporates locking coupling to position shaft of shutdown hydraulic motor relative to transmission casing. This allows complete and immediate disconnection of hydraulic motor to unload transmission hydraulic circuit in changing over to purely mechanical power transmission. ^ EFFECT: higher efficiency. ^ 9 cl, 1 dwg
