Driving engine 2 comprises having to make by connecting rod 25 and is connected in the cylinder block 28 of the cylinder 27 that the piston 26 of bent axle 6 slides and light-up plug 29 is housed and the cylinder head 30 of the valve (not shown) that suction and discharge are used.Also have, comprise variable timing formula valve lift system 31 in the cylinder head 30.Valve being carried out the rotation of the camshaft 32 of driven for opening and closing is controlled by the timing chain 33 between the driven sprocket 32a of drive sprocket 6a that is wound on bent axle 6 and camshaft 32.In addition, for power unit 7, in order to increase practical space shown in Figure 1 34, the cylinder 27 of horizontal arrangement driving engine 2 substantially.

Motor 3 adopts the periphery at stator 35 to be equipped with can be with the external rotor type motor of bent axle 6 rotor rotated 36.This motor 3 plays a part when driving engine 2 starting or accepts when requiring high output to supply with, make driving engine that bent axle 6 is rotated and the rotation of crank wheel 6 is converted to electric energy, battery unit 8 is carried out the effect of electrically-charged electrical generator from the electric power of battery unit 8 (with reference to Fig. 1).In addition, this kinetic energy is converted to electric energy, battery unit 8 is carried out electrically-charged work calls regeneration.The details of the action during for regeneration are described later.

Also have, on bent axle 6, between motor 3 and connecting rod 25, be equipped with power-transfer clutch 37 and gear 38.Power-transfer clutch 37 has makes driving engine 2 be connected and the effect that separates with motor 3, for example, is made of liquid clutch.And the related energy of Jake brake (pumping loss, mechanical loss) in the time of can making deceleration by this power-transfer clutch 37 is all regenerated.Like this, owing to return the energy of transmitting-receiving during motor braking, thereby can further improve energy recovery efficiency.Gear 38 and centrifugal clutch 41 engagements.Input shaft 42 arranged coaxial of centrifugal clutch 41 and toric transmission 4 are corresponding rotation speed and moving, the power-transfer clutch endosome with can with the power-transfer clutch ectosome bonded assembly free-wheel clutch of input shaft 42 one rotation.

Toric transmission 4 constitutes, and carries out the axle supporting with the cone 46 of driven surface 45 butts of the driven surface 43 of input shaft 42 1 sides and output shaft 44 1 sides respectively by 47 pairs of bolsters.Bolster 47 is erected on the element of cone of output shaft, and according to the rotation number of input shaft 42, centrifugal mechanism 48 makes support 49 slips of bolster 47 being carried out the axle supporting, thereby changes contact position, the change converter speed ratio of driven surface 43,45 and cone 46.

Train of reduction gears 5 is positioned at the back segment of toric transmission 4.Train of reduction gears 5 is made of gear 51, gear 52, gear 53, the gear 54 of the output shaft 44 of toric transmission 4, and each gear 51,52,53,54 meshes and power is slowed down.

Poewr transmission mechanism 61 plays a part by the driving chain 66 between the driven sprocket 65 that is wound on drive sprocket 63 in the drive wheel swing arm 62 and axletree 64 shown in Figure 1 the rotation of power unit 7 generations to be passed to trailing wheel 15R.

Drive wheel swing arm 62 is by the principal arm 62a that hides driving chain 66 and clip trailing wheel 15R, in opposite directions sub-arm 62b axletree 64 is carried out axle supporting, and principal arm 62a and sub-arm 62b are that power unit 7 shakes relatively by bearing installation respectively.Also have, connect principal arm 62a and sub-arm 62b by crossbeam 62c, to prevent 62 distortions of drive wheel swing arm in power unit 7 one sides.In addition, axletree 64 is connected in the wheel 67 of trailing wheel 15R.

Also have, as shown in Figure 1, look from the side, the suspension 70 of trailing wheel 15R is positioned at the downside of the practical space 34 of depositing the helmet etc., is erected between rear portion vehicle frame 14 and the drive wheel swing arm 62.In the present embodiment power unit 7 is provided in the front side, thereby has reserved surplus, just can enlarge practical space thus with regard to the space of giving the car body rear side.

Below, the effect of the configuration of above-mentioned battery unit 8 and driving engine 2 is described.

For this hybrid vehicle 1, battery unit 8 is configured in the symmetrical substantially position of centre line L w of relative overall width direction, the center-of-gravity position of battery unit 8 is set near the centre line L w, thereby has improved the balance of left and right directions.Also have, power unit 7 is configured between the battery unit 8, thereby driving engine 2 is positioned at forward position.Because big battery unit 8 of weight and power unit 7 centralized configuration are near the central authorities of the fore-and-aft direction of hybrid vehicle 1, thereby improved the weight balancing of fore-and-aft direction.Therefore, even when for example drive wheel swing arm 62 shakes etc., the handling of hybrid vehicle 1 also is good.Particularly, because battery unit 8 and driving engine 2 (cylinder head 30 and cylinder block 28) are configured in the front side of centre line L m, therefore, when the person of taking is sitting on the seat 20, battery unit 8 and the driving engine 2 and the person's of taking load just is dispersed in the front and back of car body, and it is just fine to control characteristic.Have, seat 20 is positioned at the rear side of centre line L m again, and this disperses before and after also helping to make the load that is added on the car body.

Also have and since battery unit 8 be provided in step base plate 24 below, thereby the center of the short transverse of car body also decreases.Have again, be in the low position that is clipped in battery unit 8 centres owing to be configured in the driving engine 2 of the front side of seat 20, thereby the center-of-gravity position of car body reduces further.

Because battery unit 8 tilted configuration, thereby the overall width of an end 81 1 sides that can make battery unit 8 just can reduce the intermediate cap 23 of vehicle thus less than the overall width of the other end 82 1 sides.After reducing intermediate cap 23, just can alleviate car body weight, improve the car body outward appearance.

In addition, the action of hybrid vehicle 1 is as follows.

At first, when hybrid vehicle 1 starting or during low speed etc., only under the situation of travelling as propulsion source with motor 3, make motor 3 runnings, make gear 38 rotations that are fixedly installed on the bent axle 6 by battery 8 power supplies.The rotation of gear 38 passes to the input shaft 42 of toric transmission 4 by centrifugal clutch 41.And the power after slowing down with toric transmission 4 speed changes, with train of reduction gears 5 passes to axletree 64 by Poewr transmission mechanism 61, makes trailing wheel 15R rotation.

When driving at a regular speed etc., only under the situation of travelling as propulsion source with driving engine 2, synchronous with the rotation of bent axle 6, make the fuel mix gas firing that is inhaled in the cylinder 27 by light-up plug 29, make piston 26 back and forth movements.The rotation of consequent bent axle 6 passes to toric transmission 4 and train of reduction gears 5 and Poewr transmission mechanism 61 as above-mentioned by centrifugal clutch 41, makes trailing wheel 15R rotation.

When load was big when high speed and when quickening etc., under the situation that motor 3 and driving engine 2 are travelled as propulsion source, the back and forth movement of the rotation of said motor 3 and piston 26 made bent axle 6 rotations.The rotation of bent axle 6 passes to toric transmission 4 and train of reduction gears 5 and Poewr transmission mechanism 61 by centrifugal clutch 41, makes trailing wheel 15R rotation.In this case, just the output after synthetic passes to trailing wheel 15R the output of the output of driving engine 2 and motor 3.

Like this, motor 3 is that driving engine comes work as the propulsion source by battery unit 8 power supplies, and when the residual capacity of each battery 8a of battery unit 8 is reduced to specified value, just need instruction by not shown control setup, make motor 3 come work, the electric power after the generating is filled (regeneration) to battery 8a as electrical generator.Have as in this case renovation process: when hybrid vehicle 1 slows down, the kinetic energy of trailing wheel 15R rotation is converted to the method for electric energy and by motor 3 at least a portion of the kinetic energy of the bent axle 6 that rotates by the output of driving engine 2 is converted to the method for electric energy under steam by motor 3.

Discharging and recharging in the travelling of hybrid vehicle 1 of this battery 8a carried out repeatedly.At this moment, because the distinguished and admirable mistake of travelling between two battery units 8 of separate configuration, battery unit 8 is just cooled off effectively.Have again, because cooling vessel 9 is positioned at the front side, so the cooling effectiveness of cooling vessel 9 is also high.

In addition, the present invention is not limited to above-mentioned embodiment.

For example, in embodiment hybrid vehicle 1 being illustrated as cart, but, also can be three-wheel vehicle or four-wheeled.

Battery unit 8 is not limited to shape that the battery 8a of elongated shape is stopped up, also can be to form a battery unit 8 by a battery 8a to wait other modes.Also have, about its configuration also needs not to be each one, also can about set a plurality of.In this case, for the balance that makes the overall width direction keeps good, preferably, the weight of the battery unit 8 that is positioned at centre line L w right side and the weight of the battery unit 8 that is positioned at the left side are equated substantially.

Also have, also can be, but constitute battery unit 8 by one-sided each two unit not battery unit 8 tilted configuration, the battery unit 8 of trailing wheel 15R one side is configured in than the battery unit 8 of the front-wheel 15F one side position further from centre line L w.Even such configuration also can be configured in driving engine 2 between the battery unit 8 of trailing wheel 15R one side, and can reduce the front side of intermediate cap 23.

Power unit 7 just is not limited to formation shown in Figure 3 and configuration, but can carries out all changes if make the device of drive wheel rotation with at least one side of driving engine and motor as propulsion source.
