摘要： A lubricating structure for a hydrostatic continuously variable transmission. The structure includes an oil path arranged at an outer circumferential side of a clutch valve, and a lubricant oil ejection hole communicating with the outer circumferential side oil path of the clutch valve and formed in the transmission shaft toward the outer circumference of the transmission shaft. In addition, the structure includes a communicating oil path that is also formed in the transmission shaft for communicating between an oil feeding passage communicating with an lubricant oil feeding source and the outer circumferential oil path of the clutch valve. A single orifice is arranged in the communicating oil path, rather than in the lubricant oil ejection hole. This configuration provides for efficient manufacturing and a high degree of freedom in setting of the lubricant oil ejection hole.

摘要： In a hydrostatic continuously variable transmission, a hydraulic pump and a hydraulic motor are connected through a hydraulic closed circuit and the capacity of the hydraulic motor is varied to vary the speed continuously. The transmission has a valve spool in a spool hole made in a transmission output shaft which rotatably holds the hydraulic pump and hydraulic motor; and the transmission output shaft incorporates outer branch oil paths which are connected with an outer passage and open to the spool hole, and an inner branch oil path which is connected with an inner passage and open to the spool hole. A right groove on the outer periphery of the valve spool enables the valve spool to move between a clutch release position in which the outer branch oil paths and the inner branch oil path are connected and a clutch engagement position in which a central land of the valve spool at least covers a high pressure clutch port; and the right groove is connected to the outside through a discharge oil path with an orifice.

摘要： A clutch mechanism for a hydrostatic continuously variable transmission has a hydraulic circuit including a high pressure oil path for feeding working oil from a hydraulic pump to a hydraulic motor and a low pressure oil path for feeding working oil from the hydraulic motor to the hydraulic pump. The clutch mechanism is located between the hydraulic pump and the hydraulic motor. A clutch valve is arranged on the transmission shaft and is slid by a centrifugal governor to cause the oil paths to be shortened. A cam plate member is arranged on the transmission shaft. A roller is engaged with the cam plate member and is moved outwardly in a diametrical direction by a centrifugal force. A roller bearing member receives a roller pressing force through outward motion of the roller. A pressure plate and shaft of the roller bearing member are separately formed and thereafter integrally formed.
