INTEGRAL TYPE POWER TRANSMISSION MECHANISM

摘要

PROBLEM TO BE SOLVED: To effectively and efficiently transmit the power of an engine to a device in a mechanism by providing a static hydraulic pressure type power transmitting mechanism having a variable displacement pump driven by a power source and a variable displacement motor hydraulically connected to the pump. SOLUTION: An integrated power transmitting mechanism 10 used for machines having a power source such as an engine 12 and a work system 14 has a static hydraulic type power transmitting mechanism 16, which is provided so that the delivery quantity of a variable displacement pump 26 can be varied between the highest position and the lowest positions by the operation of a delivery quantity controller 28. The variable displacement pump 26 is connected to the engine 12 through a pump driving device 30 and is also hydraulically communicated with a variable displacement motor 32 controlled by a capacity controller 38. In addition, the engine 12 is connected to the work system 14 through the mechanical power transmitting mechanism 10 including a full range advance and retreating gear mechanism 52 and a planetary gear device 54.
