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 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： The present invention relates to a method for controlling an automatic transmission of a vehicle which is capable of continuously changing a transmission ratio (Rt) and transmission coefficient (Ct). The method is three fold, that is, an initial stage control procedure, a special stage control procedure and a normal stage control procedure having priority in operation in this order.At the initial stage control procedure, Rt and Ct are determined, according to a plurality of indices representing a state of the vehicle, so that the vehicle is accelerated effectively, in general.At the special stage control procedure, Rt and Ct are determined, when a propelling force transmitting path for transmitting propelling force from an engine to the ground is disconnected at least at one part, so that a shock due to a recovery of said propelling force transmitting path is minimized.At the normal stage control procedure, Rt and Ct are determined so that the vehicle responds to the operation of the driver swiftly.

摘要： An overtop position is to be established in a hydrostatic type continuously variable transmission, and an increase of the maximum speed and the maintenance of power performance are to be made compatible with each other. In a hydrostatic type continuously variable transmission, the angle of inclination of a movable swash plate is controlled in such a manner that a target Ne is calculated from both RC (riding condition) and throttle valve opening, then the target Ne thus calculated is compared with an actual Ne to determine a rotational direction and DUTY of a control motor. The operation of the control motor is controlled in accordance with the thus-determined data and angle information on the angle of the movable swash plate provided from an angle sensor. In constant speed vehicular traveling, the change gear ratio is set at TOP ratio and a shift is made to OVERTOP when predetermined overtop control conditions ((1) the current change gear ratio should be at TOP position, (2) the degree opening of a throttle valve should exceed a threshold value determined according to a vehicular speed, and (3) the engine speed should exceed a preset value) are satisfied, thereby increasing the maximum vehicle speed.
