The formation of guard shield 36 is that first shroud member 37 of living cylinder head 26 and cylinder block 27 from front cover is connected on second shroud member 38 that covers remaining part.First shroud member, 37 usefulness construction bolts 41 are secured on the cylinder head 26.Thereby the distance between cylinder head 26 and the guard shield 36 can strict be set or subtract narrow, thereby produces a gas-flow resistance big when flowing between cylinder head 26 each blade 39 than cooling air, thereby helps to improve the cooling effectiveness of cooling air.In the present embodiment, special because rubber 40 is clipped between guard shield 36 and above-mentioned each blade 39, so cooling air must flow between each blade 39, thus the raising cooling effectiveness.And above-mentioned rubber 40 has the effect that the blade that suppresses cylinder head 26 sends quack sound, and each construction bolt 41 of guard shield 36 usefulness passes fixedly rubber 44 and installs on the cylinder head 26, thereby has reduced to vibrate the noise that causes.
And each construction bolt 41 of first shroud member, 37 usefulness that covers cylinder head 26 and cylinder block 27 from the front portion axially is secured on the cylinder head 26 along cylinder block 27.As long as open the service cover 49 on the cylinder block 27 axis line stretchers, first shroud member 37 of unloading lower shield 36 is service engine E easily.
By the way, the inlet hole 98 of motor E is formed on crankcase 28 tops with cylinder block 27 axes intersect with becoming the obtuse angle in perpendicular to the plane of bent axle 32, therefore when piston 30 moved on to top dead center, the mixing physical efficiency of air and fuel sucked crankcase 28 from inlet hole 98 efficiently.And, the pivot 23 that power plant P is supported on the link mechanism 24 on the vehicle frame F is placed on the position between cylinder block 27 and the inlet hole 98, therefore the desirable higher value of length from the earth point of trailing wheel Wr to pivot 23, thus the vertical vibration angle of above-mentioned power plant P reduced.Simultaneously, thus thereby the position that can reduce motor E is the gas handling system that comprises vaporizer 80 and air-strainer 81 to be reserved bigger installing space and helps increasing the capacity of container 22.And, the major part of the oil pump 105 of suction tude 99 belows is positioned in the crankcase 28 formed dimples 101, therefore when it was connected to the inlet hole 98 of suction tude 99, oil pump can not limit the riding position of suction tude 99, thereby improved the degrees of freedom of gas handling system riding position.
And, one deck is arranged with containing the film 106 that fluoroplastic and so on self lubricating material is electroplated on the input shaft 104 of oil pump 105.Therefore, even being placed on, the engaging piece of the spiral gear 102 of spiral gear of input shaft 103 and bent axle 12 can't also can obtain sufficient lubrication by in the bent axle 28 that lubricant oil are lubricated in the gearbox casing 64.So just improved above-mentioned engaging piece, also be the degrees of freedom of oil pump riding position.
Although the embodiment of the invention has been described in detail in detail above, be not to restriction to some extent, only otherwise deviate from the main points of appended claim book regulation, can make all changes to its design to the greatest extent.
For example, needn't be on input shaft 104 whole surfaces electroplated film disk 106, and just at spiral gear 103 parts or electroplated film disk 106 on one of two spiral gears 102 and 103 surface just.And input shaft 104 can be made spiral gear 103 parts and remaining part interconnects, at this moment, much less, need only be at spiral gear 103 parcel plating films 106, thus surface treatment is easy during than electroplated film disk 106 on whole input shaft 104.
As mentioned above, according to first aspect of the present invention, export in the withdrawing device with the motor of the output shaft engagement of this engine power of output by the input shaft of engine-driven equipment one, a kind of lubricating structure is provided, it is characterized in that, form one deck on the surface of at least one engaging piece in output shaft and input shaft two engaging pieces and have the film that the material of self-lubricating property is made with fluoroplastic and so on.Therefore, though this engaging piece be placed in can't position by oil lubrication on, also can obtain sufficient lubrication, thereby economize the thing of degreasing and so on, and improve the degrees of freedom of this equipment riding position.
According to second aspect of the present invention, except the described structure of first aspect, this engaging piece is placed in the crankcase of two-cycle engine, and this equipment is an oil pump.Therefore, this engaging piece can be placed in the crankcase that can't be lubricated by lubricant oil.
