In addition, rib 92e, 92g of bearing guide plate 98 and the location protuberance 92f of guide plate 98 is formed with at the bottom 92a of auxiliary equipment incorporating section 92.Bottom 92a from the bottom surface 91a of bowl-shaped part 91 to auxiliary equipment incorporating section 92 is formed with a pair guiding rib 91d guiding guide plate 98.
Be positioned at the outside wall portions 94 at rear of auxiliary equipment incorporating section 92, be formed with the packing ring installation otch 94a chimeric with the packing ring 102 inserting pulse generator distribution 101 and stator distribution 100 with the shape shown in Figure 10.Stator distribution 100 and pulse generator distribution 101 pass through in packing ring 102, are connected with the storage battery (not shown), combustion engine control (not shown) etc. storing the electric energy that generator 81 sends.
As shown in Figure 12 to Figure 15, guide plate 98 possesses: installation portion 98a; Oblique upper extension 98b, it walk around reducing gear wheel shaft supporting convex 92b from installation portion 98a to oblique back upper place extends; Oblique below extension 98c, it extends from installation portion 98a to oblique front lower place; Surrounding wall portion 98e, it is formed as specified altitude to surround mode around.
Oblique upper extension 98b and installation portion 98a extends at same plane, and covers pulse generator distribution 101.Guide plate 98 is located by the protuberance 92f of auxiliary equipment incorporating section 92 and guide plate guiding rib 91d, and rib 92e and 92g being formed on auxiliary equipment incorporating section 92 supports, the tapping bolt 99 inserting the bolt-inserting hole 98f of installation portion 98a screws togather by installing protruding 92d with the guide plate of auxiliary equipment incorporating section 92 and is installed on auxiliary equipment incorporating section 92.
As shown in Figure 5, tiltedly below extension 98c avoids the rotor 82 of generator 81 from installation portion 98a, to make bottom 98d towards the peristome 95f of the lubricating oil importing oil circuit 95f of the cylindrical portion 95a of tubular support 95
1top near mode, from rear, extend from the oblique below of crankcase 22 side direction generator cover 90 side.And, as shown in figure 12, from viewed from right flank time, tiltedly the bottom 98d of below extension 98c imports the peristome 95f of oil circuit 95f towards lubricating oil
1oliquely downward extend to the outer peripheral face of stator 83, guide plate 98 covers the stator distribution 100 extended from stator 83.
According to embodiments of the invention, on the top of the tubular support 95 of generator cover 90, be formed with the inside that is communicated with tubular support 95 with outside and lubricating oil lubricating oil being imported the inside of tubular support 95 imports oil circuit 95f, and, inside that arrange in the position leaving lubricating oil and import oil circuit 95f, that be communicated with tubular support 95 is formed with outside and oil circuit 95g discharged by the lubricating oil of removal of lubricant, the peristome 95g of lubricating oil discharge oil circuit 95g at tubular support 95
1in the side of tubular support 95, the peristome 95f1 importing oil circuit 95f than lubricating oil is more positioned at below, therefore the lubricated oily guiding rib 91c of a large amount of lubricating oil dispersed in Dynamo Room 80 guides, inflow generator 81 is inner by the inside of tubular support 95 to import oil circuit 95f from lubricating oil, if the amount of the lubricating oil of generator 81 inside reaches more than ormal weight, then lubricating oil can be made to pass through at the peristome 95f importing oil circuit 95f than lubricating oil from generator 81 inside
1the peristome 95g of oil circuit 95g discharged by the lubricating oil that low position is formed
1discharge, can with simple structure, lubricating oil be directed to generator 81 inside and guarantee the cooling performance of generator 81, and the friction loss that the lubricant drag when lubricating oil stored more than the ormal weight of generator 81 inside can be made to discharge and make generator 81 generate electricity is brought reduces, and makes the energy loss of internal combustion engine 20 reduce.
And generator cover 90 possesses the peristome 95f importing oil circuit 95f towards lubricating oil
1top expand auxiliary equipment accommodation space 88.As shown in Figure 3, when the usual running of internal combustion engine, from viewed from left surface time, bent axle 31 is rotated counterclockwise, and stores and utilizes start and deceleration gear 61 grade to disperse towards auxiliary equipment accommodation space 88 at the lubricating oil of the bottom of internal combustion engine 20.And the lubricating oil of discharging from auxiliary equipment such as starter motor 60, start and deceleration gear 61, starting driven gears 63 disperses in auxiliary equipment accommodation space 88.More lubricating oil can be collected by trapping the lubricating oil of delay of dispersing in the space expanded by this way, therefore, it is possible to a large amount of lubricating oil is directed in generator 81, not needing to arrange many lubricant passage waies guiding lubricating oil to cool, manufacturing cost can be made to reduce.In addition, even if a large amount of lubricating oil is directed in generator 81, also remaining lubricating oil can be discharged, the optimised quantity for oil cooled lubricating oil can be maintained, and the energy loss of internal combustion engine 20 is reduced further, more effectively cooled electric generator.
In addition, be provided with the guide plate 98 guiding the lubricating oil dispersed at auxiliary equipment accommodation space 88, the bottom 98d lubricating oil arranged as being positioned at tubular support 95 of this guide plate 98 imports the peristome 95f of oil circuit 95f
1top near, therefore, it is possible to be effectively collected in the lubricating oil dispersed in auxiliary equipment accommodation space 88, along guide plate 98, the lubricating oil being directed to tubular support 95 effectively imports the peristome 95f of oil circuit 95f
1, therefore, it is possible to it is inner a large amount of lubricating oil to be transported to generator 81, the effect that generator 81 is cooled increases further.
Guide plate 98 employs and covers from stator 83 to the cap assembly of stator distribution 100 that the packing ring 102 on the top being positioned at auxiliary equipment accommodation space 88 extends, and imports the peristome 95f of oil circuit 95f from the installation portion 98a of guide plate 98 towards lubricating oil
1tilted configuration, does not therefore need to increase the increase that number of components just can prevent manufacturing cost, and is effectively imported by lubricating oil in generator 81 and cooling effect is improved.
In the described embodiment, lubricating oil imports oil circuit and lubricating oil discharge oil circuit is arranged by arranging at the cylindrical portion 95a of tubular support 95 to import notch 95d and discharge notch 95e, but also can bore a hole to the top of cylindrical portion 95a and form lubricating oil importing oil circuit, bored a hole in the side, front of cylindrical portion 95a and form lubricating oil discharge oil circuit.
