    摘要: Distributing valves of a swash plate type hydraulic drive transmission can make a cylinder block smaller and reduce the number of processes and the number of parts. Distributing valves alternately switch, corresponding to the axial reciprocating motion of plungers, communication and cutoff between communication passages communicated to oil chambers opening to the inner surface of cylinder holes and low pressure ports and high pressure ports communicated to a low pressure oil passage and a high pressure oil passage opening to the inner surface of the cylinder holes.

    摘要: A hydrostatic continuously variable transmission includes a hydraulic pump and a hydraulic motor, supported by a common support shaft, and hydraulically connectable to each other through a hydraulic circuit including an inside passage and an outside passage. A clutch device includes a valve spool, which is slidably disposed in a hollow internal bore formed in the transmission support shaft. The valve spool is operable to make or interrupt fluid communication between the inside passage and the outside passage, according to the movement thereof. A governor mechanism is mounted to a pump casing of the hydraulic pump, and the governor mechanism generates a governor force corresponding to the rotating speed of a clutch cap, by use of centrifugal force generated by the rotation thereof. The valve spool is effectively moved in the hollow internal bore, using the governor force generated from the governor mechanism, to engage or disengage the clutch.

    摘要: In an engine having a dry sump type lubrication structure, a feed pump, a sub-scavenging pump, and a main scavenging pump of an oil pump are all integrally provided by disposing a feed pump rotor, a sub-scavenging pump rotor, and a main scavenging pump rotor in parallel on the same common drive shaft. This arrangement reduces the necessary size and weight of a feed pump and a scavenging pump while increasing the pumping capacity thereof The oil sump is divided into a plurality of oil sumps which are different from each other in their longitudinal and lateral positions. Oil in a first oil sump and a second oil sump is pumped by the main scavenging pump and sub-scavenging pump, respectively. A housing of the oil pump is composed of a first block, a second block, a third block, and a fourth block, wherein oil passages are provided in these blocks. The oil pumped by the main scavenging pump and the oil pumped by the sub-scavenging pump are collectively discharged in a collection discharge passage via the main scavenging pump discharge port and the sub-scavenging pump discharge port, respectively, and the oil thus collected is fed to the oil tank.

    摘要: A lubricating structure for a static hydraulic continuously variable transmission includes a central oil path axially formed at a center of a shaft of the transmission. A circumferential oil path is arranged at an inner circumferential part of a retainer between the retainer and an outer circumferential part of the transmission shaft. A diametrical oil path is in communication with the circumferential oil path and the central oil path of the shaft of said transmission. The diametrical oil path is provided with an orifice. A lubricant oil ejection hole is arranged at the retainer to eject lubricant oil from the circumferential oil path.
