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： 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.
