摘要： A cam shaft driving device for an engine which is adapted to operably associate a cam gear located on a cam shaft of an upper portion of an engine body with a driving gear on a crank shaft of a lower portion of the engine body, with this association being effected through the intermediary of a cam idling gear. In this device, first and second wall portions, mutually displaced along the axis of crank shaft rotation of the engine and projecting outwardly and laterally from both sides of the engine body, provide a receiving space. This receiving space is provided between adjacent cylinders in the engine body and is larger in laterally extending width than a diameter of the cylinders, with this width extending laterally of the cylinders and transversely of the axis of rotation of the crank shaft. A single gear holder is located in said receiving space, with this gear holder being mounted on at least one of the wall portions. The cam idling gear is rotatably supported and received on a side surface of the single gear holder. A shock absorbing, swingable boss/bearing arrangement may be provided for supporting the idling gear so as to control back lash phenomena.

摘要： A vertical power unit includes an input shaft and an output shaft which have axes in the vertical direction and are vertically arranged to each other; and a torque converter between the input shaft and the output shaft. The output shaft includes an upper output shaft connected to a turbine runner and a lower output shaft connected to the upper output shaft. An oil tank and an oil pump are provided outside the torque converter. The upper output shaft is provided with a vertical hole which communicates at an upper end with a circulation circuit of the torque converter so as to introduce the oil discharged by the oil pump into the circulation circuit, and a bottom wall which closes a lower end of the vertical hole. Thus, an working oil is constantly supplied to the circulation circuit of the torque converter through the interior of the output shaft, thereby cooling the working oil in the circulation circuit, and improves maintainability of loading devices driven by the output shaft.

摘要： A lockup clutch for a torque converter includes a pump extension, a receiving plate connected to the pump extension defining a hydraulic pressure chamber communicating with a portion between a pump impeller and a turbine impeller, a pressing plate opposed to the receiving plate for movement toward and away from the receiving plate, an annular friction clutch plate interposed between the receiving plate and the pressing plate and connected to the turbine impeller, a return spring for biasing the pressing plate in a retracting direction, and an escape bore permitting the inside and outside of the receiving plate to communicate with each other on the side of an inner periphery of the friction clutch plate. When the rotational speed of the pump impeller is increased to a value equal to or higher than a predetermined value, the pressing plate clamps the friction clutch plate in cooperation with the receiving plate under the action of a centrifugal hydraulic pressure within the hydraulic pressure chamber. Thus, the lockup clutch needs no special control but has a simple structure.

摘要： In a transmitting system for a small-sized vehicle in which a crankshaft and an input shaft of a transmission are connected to each other through a fluid transmitting device such as a torque converter. A primary reducing device, the fluid transmitting device and a shifting clutch are disposed on the crankshaft sequentially from one side of a crankcase supporting the crankshaft with a bearing interposed therebetween toward the outside, and the axial movements of the input member, the pump impeller and the turbine impeller on the crankshaft are restrained by the bearing and a nut threadedly fitted at a tip end of the crankshaft. Thus, a creep phenomenon of the fluid transmitting device can be eliminated by controlling the shifting clutch, and the shifting operation of the transmission can be conducted lightly. Moreover, the transmitting system is of a simple construction and improved in assemblability.

摘要： A multi-cylinder internal combustion engine comprising: first and second crankshafts disposed apart from and parallel with each other; first and second pistons operatively connected to the first and second crankshafts through connecting rods, respectively; and first and second cylinders for slidably accommodating therein the first and second pistons, respectively, both the crankshafts being interlocked with each other to rotate synchronously, the first and second cylinders being disposed adjacent to each other in the axial directions of the crankshafts. Vibrations due to the primary inertial force can be eliminated or alleviated without using a special balancer shaft. The size and weight of the engine are greatly reduced as compared with a conventional horizontally opposed type or V type engine.

摘要： An outboard engine system includes a casing and an engine mounted in an upper part of the casing. The casing also contains a torque converter, and a vertically arranged output shaft connected to a crankshaft through the torque converter. In the torque converter, a turbine runner is arranged above a pump impeller and connected to the output shaft, and a transmission cover is connected to an outer periphery of the pump impeller so as to cover an upper surface of the turbine runner. A drive plate is secured at its central portion to a lower end of the crankshaft by a first bolt, and an outer peripheral portion of the drive plate is secured to the transmission cover by a second bolt. The torque converter is suspended from the crankshaft via the drive plate. Thus, it is possible to provide an outboard engine system which enables support of a torque converter without using any bearing exclusively for supporting the overall weight of the torque converter, thereby reducing the cost.

摘要： In a fluid transmitting device, a plurality of first power transmission claws are inserted between adjacent ones of damper springs and secure to a clutch piston; and a plurality of second power transmission claws are inserted between adjacent ones of the damper springs so as to face the first power transmission claws, and has support portions which are connected to an outer peripheral surface of a shell of a turbine impeller via a weld formed by laser beams. The weld is formed into a linear shape extending along a circumferential direction of the shell so that the weld is melt by the laser beams to extend from an outer surface of the support portion to an inner peripheral surface of the shell. Thus, it is possible to easily perform welding between the support portions of the second power transmission claws and the shell of the turbine impeller, and to easily perform a visual inspection as to whether the welding condition is good or not.
