Fig. 2 is the left side view of the engine installation of partly cut-away; And Fig. 3 is the cutaway view along the intercepting of the line 3-3 among Fig. 2.
Driving engine 2 comprises 10, one crankcases 11 of a cylinder and allied equipment.Crankcase 11 is made of right-hand part 11a that is connected with each other and left side 11b.Cylinder 10 is installed on the crankcase 11.The head 13 of cylinder is installed on the top of cylinder 10, and light-up plug 14 is arranged on the head 13 of cylinder.
Piston 16 is slidingly arranged in the cylinder 10, and it links to each other with bent axle 17 by a pipe link 18.
Driving engine 2 is by transmission gearbox 20 supportings of power transfer part 3.Transmission gearbox 20 is made of a left shell 21 and a right shell body 22.Left shell is made of one first housing 23 and one second housing 24.First housing 23 is made of a front case 23a and a rear housing 23b again.
As shown in Figure 2, on crankcase 11, be formed with a plurality of patchholes 25 with the spacing that equates.As shown in Figure 3, the 21a of wall portion that lays respectively at left shell 21 corresponding to the patchhole 21b and the 22b of patchhole 25 go up and the 22a of wall portion of right shell body 22 on.Make bolt B 1Pass these patchholes 25,21b and 22b.Bolt B 1Two ends be bearing on 21a of wall portion and the 22a by rubber bush 27 and sleeve pipe 28 as shock-absorbing piece.Therefore, driving engine 2 is bearing in transmission housing 20 sides in the mode of floating.
In this embodiment, driving engine 2 is bearing in three points (a) among Fig. 2 in the mode of floating, (b) and (c).But, because patchhole 25 is located at 3 or more on the multiple spot, driving engine 2 can be by mobile bolt B with respect to the angle of transmission gearbox 20 1, B 1And B 1, rolling motor 2 is also used bolt B more forward or backward 1, B 1And B 1Fastening driving engine 2 and changing.
As shown in Figure 3, near the end of bent axle 17, be provided with an ACG32, and fan 35 grades are located at the outside of ACG32.
Housing component 50 and 51 integrally is located at respectively on left shell 21 and the right shell body 22.Housing 53 links to each other with 51 with housing component 50.Body skin 54 is connected with the outside of housing 53.Elastic component 55 is arranged between housing 53 and the body skin 54.
The transmission device 35 that is arranged on the present embodiment in the transmission gearbox 20 is described below.
Bent axle 17 stretches out in transmission gearbox 20.Driving wheel 37 is located at partly locating towards case 20 in-to-ins of bent axle 17.Thereby driving wheel 37 comprises a plate-like stationary plane 37a who cooperates with the end of bent axle 17 and one and is located on the bent axle 17 towards the stationary plane 37a and the plate-like movable surface 37b that can slide vertically.
On the other hand, 40, one tween drive shafts 41 of an input shaft and axletree 42 are arranged on the rear portion of transmission gearbox 20 rotationally.Follower 43 is located on the input shaft 40.Thereby follower 43 is fixed on plate-like stationary plane 43a on the input shaft 40 and one by one and is arranged on rotationally on the input shaft 40 and can constitutes along the movable surface 43b that input shaft 40 slides.V-arrangement skin normal 44 is suspended between follower 43 and the driving wheel 37.
Gear 45 is located at the end of input shaft 40, and it is arranged on gear 46 usefulness screws on the tween drive shaft 41 etc. with one and is tightened in.Gears 48 on being arranged on axletree 42 such as gear 47 usefulness screws that are arranged on the tween drive shaft 41 are tightened in.Therefore, the rotation of bent axle 17 reaches input shaft 40 by V-shape belt 44 from driving wheel 37.Then, this rotation reaches tween drive shaft 41 by gear 45 and 46, and passes to axletree 42 again by means of gear 47 and 48, and trailing wheel W is rotated.
As shown in Figure 2, mounting portion 49 is positioned on the lower surface of transmission gearbox 20.As shown in Figure 1, the rear end side of the rocking bar 50 that pivotally supported by vehicle frame of its front end is supported pivotally by mounting portion 49.
As shown in Figure 2, carriage 60 is contained in the front portion of silencer 5, and flange 61 is arranged on the right shell body 22 of transmission gearbox 20.Flange 61 and carriage 60 use bolt B 7 fastening each other.Therefore, silencer 5 is by transmission gearbox 20 supportings.
In this embodiment, shown in Fig. 2 and 3, between crankcase 11 and transmission gearbox 20, form a space 62, and between left shell 21 and right shell body 22, form an exhaust outlet 63 that makes the cooling air transpiration, this exhaust outlet be oriented along in the trailing wheel periphery of power pack section back towards oblique downside.
When fan 35 rotations, cold wind is flowed along the direction of the arrow in Fig. 2 and 3.Cold wind passes the space 62 between crankcase 11 and the transmission gearbox 20, and as shown by arrows drain into the external world from exhaust outlet 63 like that.
Thus, crankcase 11 so the crankcase 11 inner heats that produce can positively be discharged, thereby causes the improvement of cooling effectiveness by the cold wind cooling of passing space 62.
In this embodiment, be provided with an exhaust outlet 63 further, thereby cold wind is flowed energetically, improve cooling effectiveness thus further.In addition, even when the space 62 between water, sand and analogue infiltration crankcase 11 and the transmission gearbox 20, they also can drain into the external world from exhaust outlet 63.
Power Generation Unit of the present invention can be a motor, and cold wind do not produce by cooling fan of engine, and may be the wind that flows.
Fig. 4 represents another embodiment.In this embodiment, oil pump 70 is located at the front portion of transmission gearbox 20.Oil pump 70 connects crankcase 17 by adapter shaft 71, and is formed at the gear 72 and crankcase 17 engagements of transmission gearbox 20 front ends.Adapter shaft 71 inserts and is formed in the opening 73 of transmission gearbox 20 front ends, this opening be oriented along in the trailing wheel periphery of power pack section back towards oblique downside.
According to the structure of present embodiment, cold wind can be discharged from opening 73.As mentioned above, according to the present invention, owing to formed a space between power pack section and power transfer part, can make cold wind flow through this space, this must take away the heat that the power pack section side is produced, and improves cooling effectiveness therefrom.In addition,, can make cold wind be easy to flow, therefore improve cooling effectiveness further owing to be provided with an exhaust outlet.In addition, owing to be provided with exhaust outlet, even when sand and analogue infiltrate this space, also they can be drained into space outerpace from exhaust outlet.
