摘要： An engine (2) includes a crankshaft (40), and a speed changer (60) having a driving pulley shaft (62) and a driven pulley shaft (64) includes a crankcase (20) which can be split on a splitting plane passing along an axis (P1) of the crankshaft (40), and a transmission case (30). In the engine (2), the transmission case (30) has members (30a) and (30b) unitarily formed while including a driving-side pivot supports (33a) and (33b) for pivotally supporting the driving pulley shaft (62) and a driven-side pivot supports (34a) and (34b) for pivotally supporting the driven pulley shaft (64). One part 20a of the crankcase (20) from the splitting plane is combined with a section among the members (30a) and (30b) of the transmission case (30). The other part (20b) of the crankcase from the splitting surface is combined with another section among the members (30a) and (30b) of the transmission case.

摘要： A drive unit case (920) in this engine unit is provided with a crank shaft (60) disposed in the left-right direction of the vehicle, a drive shaft (73) and a second main shaft (72). A transmission shaft (79) is disposed parallel to the drive shaft (73) and transmits rotational power, which has been transmitted via a middle gear (76), to a propeller shaft (65). A second clutch (75), which transmits rotational power from the crank shaft (60) to the second main shaft (72), is connected freely detachably to an end (72a) of one side of the second main shaft (72) which protrudes from a drive unit case (920) more than the end of one side of the drive shaft (73), at a position that overlaps with at least one section of the middle gear (76) on the side of the shaft direction of the drive shaft (73).

摘要： A power unit is provided that reduces the frictional resistance between a clutch and a rotary shaft while at the same time prevents an increase in the size thereof. The power unit includes an oil catch member (39) having an inner circumferential surface (39a) positioned radially outward of a rotary shaft (21) relative to an outer circumferential surface (21a) of the rotary shaft (21) and spaced apart from the outer circumferential surface (21a). At least a portion of the oil catch member (39) is disposed between a bearing (34) and a first clutch member (25). An oil reservoir space (45) for storing oil is formed between the inner circumferential surface (39a) of the oil catch member (39) and the outer circumferential surface (21a) of the rotary shaft (21), the oil reservoir space (45) being in communication with a clearance gap (37) between the outer circumferential surface (21a) of the rotary shaft (21) and an inner circumferential surface (36a) of a bore (36) of the first clutch member (25).

摘要： The present disclosure relates to a lubrication system for an engine (100). The lubrication system includes a gear case (104) having a conduit (316) for drainage of an accumulated fluid (402). When the engine (100) is oriented horizontally, fluid such as a lubricant tends to accumulate within the gear case (104). The present disclosure provides an internal wall (314) within the gear case (104) for directing the fluid (402) into a confined space of the conduit (316) defined by the internal wall (104) configured to allow the fluid to be channeled and drained out of the gear case (104) in use.

摘要： A gear-shifting mechanism for vehicles has a crankcase (10), a gearbox (20) and a reserved room (30). Because the reserved room (30) is formed between a first case (11) of the crankcase (10) and a body (21) of the gearbox (20), a shift lever (14) can protrude out of the first case (11) and is mounted into the reserved room (30) to connect to a transmission between the crankcase (10) and the gearbox (20). Besides, the shift lever (14) also can protrude out of a second case (12) to connect to a transmission opposite to the gearbox (20). As a result, the shift lever (14) can output in two directions, applicable for the gearbox (20) in left or right of the crankcase (10). An engine connected to the gear-shifting mechanism can be adapted for various vehicles.

摘要： In a power unit for a small vehicle in which, in a gear chamber within a gear case, a gear mechanism having a drive gear, a final gear mounted on an axle of a drive wheel, and a counter gear arranged between the final gear and the drive gear is contained within the gear chamber, a reduction in rotation friction is made possible while ensuring lubrication performance based on oil splashes from the final gear. A rotation axis C1 of the final gear (85) with a lower portion immersed in oil within the gear chamber is placed at a higher level than rotation axes C2, C3 of the drive gear (84) and the counter gears (86, 87). An oiling rib (104) placed above the final gear (85) and extending toward the final gear (85) protrudes into the gear case. The gear case is provided with an oil guide wall (105) formed in an arc shape along the tooth tips of the final gear (85) to guide the oil in a lower portion in the gear chamber to the oiling rib (104).
