Abstract: A crankshaft supporting structure in a multicylinder internal combustion engine has a cylinder block made of a light alloy and including a cylinder housing and a crankcase having a plurality of spaced journal walls. A plurality of spaced bearing caps made of an iron alloy are coupled respectively to the journal walls. A crankshaft is rotatably supported in bearing holes defined by the journal walls and the bearing caps. A bridge made of a light alloy extends across the bearing caps and is coupled to the bearing caps. The bearing caps and the bridge are fastened together to the journal walls by connecting bolts disposed one on each side of the crankshaft. The bridge has a main portion defining a main gallery extending longitudinally therethrough and a plurality of legs coupled to the bearing caps, respectively. The bearing caps and the legs jointly define branch oil passages communicating with the main gallery and the bearing holes. In one embodiment, each of the oil passages has a longitudinal central axis displaced transversely from the central axis of the cylinder housing passing through the center of the crankshaft.

Abstract: A front wheel suspension assembly for a motorcycle includes parallel telescoping forks of the hydraulic shock absorber type which straddle the wheel and which are inclined in a forward direction. The bending moment imposed on the telescoping parts by this inclination is partly or fully opposed by a counter bending moment imposed by one or more springs positioned rearward of a vertical plane containing the wheel axis and below a bottom bridge joining the front fork tubes. The purpose is to reduce the frictional resistance between telescoping forks in their axial sliding motion. The springs apply the compensating bending moment between the telescoping parts.

Abstract: A cylinder block structure of a light alloy for use in a multicylinder internal combustion engine includes a cylinder-defining portion having a plurality of cylinder bores with a water jacket defined in surrounding relation to the cylinder bores, and a crankcase-defining portion integrally formed with the cylinder-defining portion and having a plurality of integral journal walls spaced in the direction in which the cylinder bores are arranged. Concavities are defined in opposite sides of the cylinder- and crankcase-defining portions between the adjacent cylinder bores, the concavities lying between the water jacket and journal walls. A plurality of reinforcing rib systems project from the opposite sides of the cylinder block and each rib system surrounds one of the concavities. The concavities reduce the amount of molten metal to be poured in casting the cylinder block structure, for thereby preventing casting defects such as cavities from being produced in the cylinder block. The reinforcing rib systems serve to provide the required degree of stiffness to the cylinder block. Since the reinforcing rib systems terminate short of the deck of the cylinder block, no vibration is transmitted through the reinforcing rib systems to the deck, whereby the deck is prevented from being subject to deflecting vibration.

Abstract: The crankshaft of an engine is supported by bearing caps mounted on journal walls of a cylinder block and a bridge interconnects the bearing caps. Oil passages in each bearing cap lead from the bridge to each crankshaft journal bearing at a laterally offset location rather than on the cylinder axis. A longitudinal main gallery in the bridge supplies oil to the passages and is laterally offset even further to that side. A supply passage in the bridge and one bearing cap at one extreme lateral side supplies oil from a pressurized oil supply passage in the cylinder block to that supply passage in the bearing cap.
