Below, this working of an invention form is described.
(working of an invention form 1)
In Fig. 1 to Fig. 5, showed this working of an invention form 1.
At first, formation is described, label 11 among Fig. 1, are the motors that is provided in as 4 circulations of the single cylinder on the motor bike of riding vehicle, 4 valves, are provided with bent axle 12 on this motor 11, via connecting rod 13 bindings piston 14 arranged on this bent axle 12.
Constitute in such a way, promptly move up and down in cylinder 15 by this piston 14, making bent axle 12 via connecting rod 13 is the center rotation with the axle along the overall width direction.
And, with respect to the axle center O 2 of this bent axle 12, with the axle center O 1 of cylinder 15 to side's side (front side) biasing specific length.By such biasing, wasted power diminishes when piston 14 has been subjected to firing pressure thereby be set at.
In addition, the 1st parallel lines L1 parallel with respect to intersecting with the axle center O 1 of cylinder 15 with the axle center O 2 of bent axle 12, with the opposite side of a side with 1 biasing of cylinder axis center O on, dispose balace weight axle 18.
With respect to the 1st parallel lines L1, with a side of configuration balace weight axle 18 mutually on the same side, dispose main shaft 19, this balace weight axle 18 is configured in than main shaft 19 more close cylinder 15 sides simultaneously.Under the configuration status of motor shown in Figure 1 11, main shaft 19 is configured on the neutral position of above-below direction of this bent axle 12 and balace weight axle 18.
On this balace weight axle 18, as shown in Figure 3, be formed with balace weight gear 18b and balace weight counterweight 18c, this balace weight axle 18 is supported freely by pair of bearings 22,22 rotations that are located on the crankcase 21, aforementioned balace weight counterweight 18c is between this a pair of bearing 22,22, and aforementioned balace weight gear 18b is provided in right-hand end among Fig. 3 simultaneously.
And this balace weight counterweight 18c is inserted between a pair of crankweb 12a of bent axle 12, and is constituted as the rotating locus 18d of this balace weight counterweight 18c and the rotating locus 12d of crankweb 12a, sees coincidence from bent axle 12 directions.In addition, the mode that is positioned on the elongated surfaces of profile of cylinder 15 with the rotating locus 18d of this balace weight counterweight 18c is set.
In addition, balace weight gear 18b is meshed with the crankshaft gear 12b of bent axle 12.This crankshaft gear 12b is identical diameter with balace weight gear 18b.
And then, as shown in Figure 4, being located at the driving side one-level reduction gear 24 of these bent axle 12 sides, the side one-level reduction gear 25 that is driven that is located at freely on the main shaft 19 with rotation is meshed.And to come from the driving force that this is driven side one-level reduction gear 25, the mode that passes to main shaft 19 via clutch mechanism 26 constitutes.
On this main shaft 19, be equipped with 1 fast gear 27,2 fast gear 28,3 fast gear 29,4 fast gear 30,5 fast gears 31 and 6 fast gears 32, this 5 fast gear 31 and 6 fast gears 32 are provided in the both end sides of each gear 27..., and, side sets 1 fast gear 27 and 2 fast gears 28 within it, and then, between these 1 fast gears 27 and 2 fast gears 28 (center side of each gear 27...), set diameter 3 fast gears 29 and the 4 fast gears 30 littler than maximum 1 fast gear 27.
And, as shown in Figure 4, be configured to make the front end of the front end of aforementioned balace weight counterweight 18c over against these 4 fast gears 30.Thus, with the big gear 27 of the diameter in the main shaft 19 be located at the rotating locus of the balace weight counterweight 18c on the aforementioned balace weight axle 18, see the mode of coincidence, set the axle base of main shaft 19 and balace weight axle 18 from axle direction.
And then, near the upside of balace weight axle 18, as shown in Figure 2, dispose starting motor 35, this starting motor 35, the left side is fitted in the left case 37 of crankcase 21 from Fig. 3.
And the starting gear 35a of this starting motor 35 is projected in the left case 37, and this starting gear 35a is meshed with the large diameter gear 39a of pony axle 39, and the small-diameter gear 39b of this pony axle 39 is meshed with the binding gear 12c of bent axle 12 simultaneously.Thus, when driving starting motor 35, just via pony axle 39 rotary crankshafts 12.
This starting motor 35, as Fig. 2 and shown in Figure 3, with when the side is seen, the mode that overlaps with the balace weight gear 18b and the balace weight counterweight 18c of balace weight axle 18 disposes.
For such motor, when balace weight axle 18 is configured in the rear side oblique upper of bent axle 12, though the piston skirt 15a of cylinder 15 becomes obstruction near balace weight counterweight 18c, but at this, because axle center O 2 with respect to this bent axle 12, to side's side (front side) biasing specific length, so the position of the piston skirt 15a of cylinder 15 is also to biased direction (rear) skew, so can be with the space enlargement amount suitable with it that set of balace weight axle 18 with the axle center O 1 of cylinder 15.And,, can shorten the distance of balace weight axle 18 and the 1st parallel lines L1 by balace weight axle 18 is provided on this position.
In addition, though be provided with clutch mechanism 26, owing to do not wish that this clutch mechanism 26 is immersed in the gasoline, the motor 11 more convenient uses of holding up simultaneously in the end of main shaft 19, therefore under the state that motor 11 is holded up, wish to set main shaft 19 higher.
So, disturbing for fear of the gear 27... of balace weight counterweight 18c and main shaft 19, balace weight axle 18 is just farther from main shaft 19, and it is big that the profile of motor 11 will become.That is, this is because because the rotation of balace weight axle 18 and the rotation of bent axle 12 must be 1: 1, so the distance of balace weight axle 18 and main shaft 19 is far away, and the diameter of balace weight gear 18b will become big cause.
So at this, 3 speed or 4 fast gears 29,30 that the footpath of main shaft 19 is less are configured in center side, and dispose in the mode of front end front end of 4 less fast gears 30 over against this footpath of balace weight counterweight 18c.Promptly, owing to make bigger gear (1 fast gear 27) and the rotating locus of balace weight counterweight 18c in footpath in the main shaft 19 see coincidence from axle direction, therefore can shorten the distance of main shaft 19 and balace weight axle 18, and the axle base of balace weight axle 18 and bent axle 12 can be shortened the amount suitable with it, so can dwindle the diameter of balace weight gear 18b, the result can seek the miniaturization of motor 11.

By the way,, will become the position that dabbles,, will be immersed in the gasoline, bring obstacle for the driving of motor 11, therefore can not dispose simultaneously if balace weight axle 18 is configured in downside if starting motor 35 is configured in the front side of motor 11.These problems just can be eliminated by this example.
In addition, discharge pressure in the firing chamber, can reduce the driving force of starting motor 35, therefore can seek the miniaturization of starting motor 35, and can be configured in the recess 37a of left case 37 by the decompressor that utilizes detailed.
And,, therefore can be configured in ratio engine center O 3 more close left sides owing to can adopt less starting motor 35.,, therefore be configured on the engine center O3 in the past, can not realize seeing the configuration that starting motor and balace weight counterweight 18c are overlapped from the side because starting motor is bigger.
And then, balace weight axle 18 and starting motor 35 are configured in the back side top of bent axle 12, balace weight gear 18b and starting motor 35 are seen overlapping from the side.
By such configuration, can seek the compactness of motor 11 integral body.In addition,, be configured in the recess 37a of left case 37, therefore can dispose starting motor 35 effectively because starting motor 35 is inserted by left side from Fig. 3 of the left case 37 of crankcase 21.
And, by with motor 11 compactnesss, can enlarge the upside that is configured in balace weight axle 18 and starting motor 35 suction system set the space.
And then, as shown in Figure 3, because the balace weight counterweight 18c of balace weight axle 18 is inserted between a pair of crankweb 12a of bent axle 12, and see from the side that with balace weight counterweight 18c and crankweb 12a overlapping mode disposes, therefore the axle base of balace weight axle 18 and bent axle 12 can be shortened, and the compactness of motor 11 can be sought.
Again and then, because the bearing 22 and the pony axle 39 of balace weight axle 18 be configured to see coincidence from the side, therefore can set the axle base of these pony axles 39 and balace weight axle 18 and bent axle 12 shortly.
And as shown in Figure 1, clutch mechanism 26 and starting motor 35 are set in the mode of seeing coincidence from the side.Thus, can make the axle base of starting gear 35a and main shaft 19 approaching, and can enlarge the space that sets of suction system.
Moreover, shown in double dot dash line among Fig. 5, even if with respect to the axle center O 2 that comprises bent axle 12 and perpendicular to the 1st plane P 1 of the axle center O 1 of cylinder 15, balace weight axle 18 is configured under the situation with cylinder 15 opposite sides, overlap with the rotating locus 12d of crankweb 12a by rotating locus 18d, also can make balace weight axle 18 near the 1st parallel lines L1 with balace weight counterweight 18c.
(working of an invention form 2)
In Fig. 6, showed this working of an invention form 2.
This example 2 is that starting motor 35 is configured near the rotating locus 12d of crankweb 12a form.That is,, balace weight axle 18 is configured in cylinder 15 sides,, is configured near the rotating locus 12d of crankweb 12a, and be configured in a side opposite with cylinder 15 sides compared to the 1st plane P 1 simultaneously with starting motor 35 with respect to aforementioned the 1st plane P 1.
