    摘要: To reduce the projection of a swash plate servo mechanism in the radial direction, and to make a hydraulic continuously variable transmission compact, a swash plate plunger pump includes a pump casing provided with an input driven gear. A pump cylinder and a motor cylinder are connected to a transmission output shaft, and a motor pivot member provided with a motor swash plate member is supported to be pivotally movable. A motor servo mechanism includes a ball screw shaft, a ball nut to which an end portion of the motor pivot member is connected, and a swash plate control motor to rotate the screw shaft. A swash plate control motor, located on the side of a hydraulic pump relative to the input driven gear, is mounted to the outside surface of a transmission housing close to the center axis side of a transmission output shaft.

    摘要: A powertrain unit includes a hydraulic continuously variable transmission including a transmission housing, and a dipstick for checking an oil level in the housing. The width of the powertrain unit is reduced by positioning the dipstick laterally inside the housing. The hydraulic continuously variable transmission includes a fixed-displacement swash plate plunger pump and a variable displacement swash plate plunger motor, which are connected through a closed hydraulic circuit. The outer circumference of a portion of a pump casing of the plunger pump for is reduced in diameter to form a reduced diameter portion. The dipstick is positioned so that a gauge portion thereof extends from an area near the outer circumference of the reduced diameter portion down to the bottom of the transmission housing.

    摘要: A lubricating system for an internal combustion engine includes lubricating oil recovery oil passages through which lubricating oil dropping to and dwelling in a bottom portion of a crankcase after lubricating individual portions of an internal combustion engine is fed to a lubricating oil tank through an oil cooler by a recovery pump. Lubricating oil supply oil passages supply the lubricating oil from the lubricating oil tank to the individual portions of the internal combustion engine needing lubrication and cooling through an oil filter by a supply pump. The lubricating system includes a branch passage branched from the lubricating oil recovery oil passage communicating from the oil cooler to the lubricating oil tank. The branch passage supplies the lubricating oil to at least one of the individual portions of the internal combustion engine.

    摘要: A lubricating system for an internal combustion engine includes a recovery pump by which a lubricating oil dropping to and dwelling in a bottom portion of a crankcase after lubricating individual portions of the internal combustion engine is sucked through a pump suction port opened in the bottom portion of the crankcase and is fed to a lubricating oil tank. A supply pump is provided for supplying the lubricating oil from the oil tank to the individual portions of the internal combustion engine. The lubricating tank is integral with the crankcase and is partitioned from a crank chamber by a partition wall projecting from the inside wall of the crankcase. The lubricating system includes an overflow oil passage through which the lubricating oil that flows over the upper edge of a partition wall of the lubricating tank is led to a suction port of the recovery pump.

    摘要: A crankshaft holding structure 10 for use in an internal combustion engine has a front crankshaft 35 supported by a radial roller bearing 25 that is fixed to a crankcase 11 and has an inner side surface 26a. A land 40 of the front crankshaft 35 is held in abutment against the inner side surface 26a to limit crankshafts 30, 35 against axial elongation and deformation. The radial roller bearing 25 has an outside diameter D1 that is the same as an outside diameter of a radial ball bearing 20. The forgoing arrangement includes simplified bushings cast in a crankcase and having bearing press-fitted therein, that allows the bushings to be used as common parts.

    摘要: An oil passage extending from an oil pump to a discharge port in an internal combustion engine is, at its halfway point, branched into at least two oil passages, for example, a first oil passage and a second oil passage. One of the at least two branched oil passages, for example, the second oil passage is provided with a restricting portion configured as a first orifice for restricting a flow amount of oil by reducing a diameter of the first orifice. A bypass valve is provided which acts, when a hydraulic pressure in the second oil passage exceeds a specific value, to bypass the first orifice so as to increase the flow rate of oil. It is possible to increase the hydraulic pressure at the time of low speed rotation up to a necessary pressure only by providing the restricting portion, without enhancing the performance of the oil pump. Accordingly, it is possible to suppress the increase in weight and cost of the lubricating system as compared with the prior art lubricating system in which the performance of the oil pump is enhanced, and since it is not required to increase the rotational speed of the oil pump, it is possible to prevent the loss in output of the internal combustion engine due to the increased friction of the oil pump. Further, it is possible to prevent an excessive increase in pressure of the oil passage by the effect of the bypass valve.
