摘要： A power transmission device for an astride-riding vehicle is provided, the power transmission device including a torque converter T and a clutch C disposed in series in a transmission route between an engine E and a gear speed change device M. The torque converter T is arranged so that a pump capacity τ is a maximum at a speed ratio e=0, and gradually decreases in response to an increase in the speed ratio e. Linear properties in which both the engine rotational speed and the turbine rotational speed increase substantially linearly in response to an acceleration operation of the engine can therefore be obtained, thereby providing good drivability.

摘要： In a transmitting system for a small-sized vehicle in which a crankshaft of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device, the fluid transmitting device and a shifting clutch are mounted on the crankshaft. One of the fluid transmitting device and the shifting clutch is connected to the crankshaft, while the other is connected to the input shaft of the multi-stage transmission through a primary reducing device. Provided in the crankshaft are an upstream supply oil passage connected to an oil pump, a downstream supply oil passage connected to portions to be lubricated of the engine, a flow-in bore which permits the upstream supply oil passage to communicate with the inside of the fluid transmitting device, and a flow-out bore which permits the inside of the fluid transmitting device to communicate with the downstream supply oil passage.

摘要： A torque converter includes a pump impeller, a turbine impeller, a stator impeller disposed between the pump impeller and the turbine impeller, and a free wheel which is interposed between the stator impeller and a stationary case and operable to lock the stator impeller in order to allow the stator impeller to bear a reaction force generated with the amplification of torque between the pump and turbine impellers. In this torque converter, a stator shaft connected to the stator impeller is disposed with its tip end being passed through a turbine shaft to protrude outside the turbine shaft. The free wheel is interposed between the tip end of the stator shaft and the stationary case. Thus, it is possible to reduce the diameter of the stator impeller and thus, the diameter of the entire torque converter, irrespective of the presence of the free wheel inhibiting the rotation of the stator impeller.

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.

摘要： In a transmitting system for a small-sized vehicle in which a crankshaft of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device, a shifting clutch is interposed between the crankshaft of the engine and the multi-stage transmission in a series relation to the fluid transmitting device. A lock-up clutch is interposed between a pump impeller and a turbine impeller of the fluid transmitting device. Thus, when the multi-stage transmission is to be shifted, the shifting operation can be conducted lightly, in spite of a creep phenomenon of the fluid transmitting device, by bringing the shifting clutch into an OFF state. Moreover, during cruising of the vehicle, the slipping of the fluid transmitting device can be inhibited by the OFF state of the lock-up clutch to enhance the transmitting efficiency.

摘要： The inlet and outlet passages communicating with a water-cooled engine oil cooler for a vehicle, such as a motorcycle, are arranged for bypass of a regulated amount of oil from the inlet passage to the outlet passage to enhance the flowability of the cooled oil. Provision is made for a replaceable flow control orifice between the oil inlet and outlet passages to regulate oil viscosity. Also described is an arrangement providing for mounting the cooler to the crankcase or oil pan surface whereby air flowing past the cooler during movement of the vehicle assists the effects of the cooling liquid.

摘要： In a fluid transmission device, a male fitting surface of a periphery of a diameter-expanded portion of a pump shell is fitted to a female fitting surface of an inner circumference of a peripheral wall portion of a cylindrical transmission cover, and a fillet weld being is formed between an end surface of the peripheral wall portion and a peripheral surface of the diameter-expanded portion along an entire circumference, thereby connecting together the pump shell and the transmission cover. An annular recess is formed in an inner circumferential surface of the peripheral wall portion to adjoin the female fitting surface on the side opposite from the fillet weld. A portion of the transmission cover corresponding to the recess constitutes an annular thin-walled portion which has a thickness smaller than the portions of the transmission cover along the opposite sides of the annular thin wall portion. Therefore, even if the diameters of the pump shell and the transmission cover are increased, the durability of the pump shell and the transmission cover can be improved by alleviating excessive stress concentration on the fillet weld between the pump shell and the transmission cover.
摘要翻译：在流体传动装置中，泵壳的直径扩大部分的周边的阳配合表面装配到圆柱形传动罩的周壁部分的内圆周的阴配合表面上，并且角焊沿圆周方向形成在周壁部的端面与直径扩大部的周面之间，由此将泵壳与变速器罩连接起来。在周壁部的内周面形成有环状的凹部，以与与内角焊缝相反一侧的阴配合面相邻。对应于凹部的传动罩的一部分构成环形薄壁部分，该环形薄壁部分的厚度小于沿着环形薄壁部分的相对侧的变速箱盖部分的厚度。因此，即使泵壳和变速箱盖的直径增大，也可以通过减轻泵壳与变速箱盖之间的角焊缝上的过度的应力集中来提高泵壳和变速器盖的耐久性。

摘要： A torque converter includes a turbine impeller integrally connected to a pump impeller, a side-cover having a boss and covering the turbine impeller, and a turbine shaft extending through the boss and connected to the turbine impeller. A radial bearing and a one-way clutch are disposed axially adjacent to each other between the boss of the side-cover and the turbine shaft. The radial bearing serves to retain the boss and the turbine shaft concentrically, and the one-way clutch connects the turbine shaft and the side-cover to each other, when a back load is applied to the turbine shaft. Therefore, a load received by a clutch element of the one-way clutch such as a sprag between the turbine shaft and the side-cover is equalized. Thus, when a back load is applied to the turbine shaft, a slipping between the turbine impeller and the pump impeller is prevented, thereby providing a good engine brake effect.
摘要翻译：变矩器包括与泵叶轮一体连接的涡轮机叶轮，具有凸台并覆盖涡轮叶轮的侧盖以及延伸穿过凸台并连接到涡轮叶轮的涡轮轴。径向轴承和单向离合器在侧盖的凸台与涡轮轴之间彼此轴向地相邻布置。当向涡轮机轴施加后负荷时，径向轴承用于同心地保持凸台和涡轮轴，并且单向离合器将涡轮轴和侧盖相互连接。因此，在涡轮轴和侧盖之间的诸如楔子之类的单向离合器的离合器元件所接收的负载相等。因此，当向涡轮轴施加背负载时，防止涡轮叶轮与泵叶轮之间的滑动，从而提供良好的发动机制动效果。
