For the compact(ing) machine of hybrid vehicleTechnical field
The utility model relates to machine field, is specially a kind of compact(ing) machine for hybrid vehicle.
Background technology
Along with the day by day scarcity of the energy and day by day increasing the weight of of environmental pollution, the New-energy electric vehicle with effects of energy conservation and environmental protection has become the Main way of future automobile development gradually, and hybrid vehicle is one of mainstream technology direction being acknowledged as the development of current new-energy automobile.Hybrid vehicle is compared with pure electric automobile, power assembly is more complicated, more and more harsher to structure space layout requirements, particularly hybrid power system is integrally assembled into for collection engine, motor, clutch, gearbox, space layout is comparatively compact, and the internal structure of current motor is difficult to realize to take into account in limited arrangement space power density and heat dispersion to reach the powerful performance of high rotating speed.
Utility model content
In order to overcome the defect of prior art, providing that a kind of volume is little, power density is high, dispel the heat good motor, the utility model discloses a kind of compact(ing) machine for hybrid vehicle.
The utility model reaches goal of the invention by following technical solution:
For a compact(ing) machine for hybrid vehicle, comprise stator case, it is characterized in that: also comprise stator, turn hub, rotor core and magnetic pole, resolver stator, rotary transformer rotor and transition axis,
Stator comprises iron core and winding, and rotor comprises iron core and magnetic pole;
The side of stator case is directly connected with the cylinder body of engine, and the opposite side of stator case is connected with gear box casing, the cooperation plane of stator case both sides is all used two alignment pin location;
The iron core of rotor and magnetic pole are all fixed on and turn on hub, and the one end turning hub is connected with engine crankshaft by transition axis, and the other end turning hub is connected with clutch cover and plate assembly;
In cavity within rotor internal diameter, stator case is provided with outstanding ring-type convex, resolver stator is fixed on the ring-type convex of described stator case, turns hub and is provided with outstanding ring-type convex, and rotary transformer rotor is fixed on and described turns on the ring-type convex of hub;
The inwall of stator case is provided with water channel, and in water channel water channel, circulation cooling fluid is to take away heat.
The described compact(ing) machine for hybrid vehicle, is characterized in that: the heat-conducting insulation material that in the gap between stator case and stator, embedding density is little is to improve radiating efficiency.
The utility model topology layout is compact, and the stators and rotators of motor, the stators and rotators of resolver all centralized layout, in same radial space, significantly reduce axial dimension, and whole motor is had, and volume is little, power density is high, the advantage such as good of dispelling the heat.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
For a compact(ing) machine for hybrid vehicle, comprise stator case 1, stator 2, turn hub 3, rotor core and magnetic pole 4, resolver stator 5, rotary transformer rotor 6 and transition axis 7, as shown in Figure 1, concrete structure is:
Stator 2 comprises iron core and winding, and rotor 4 comprises iron core and magnetic pole;
The side of stator case 1 is directly connected with the cylinder body of engine 10, and the opposite side of stator case 1 is connected with gear box casing 13, the cooperation plane of stator case 1 both sides is all used two alignment pin location;
The iron core of rotor 4 and magnetic pole are all fixed on and turn on hub 3, and the one end turning hub 3 is connected with engine crankshaft by transition axis 7, and the other end turning hub 3 is connected with clutch cover and plate assembly 12;
In cavity within rotor 4 internal diameter, stator case 1 is provided with outstanding ring-type convex, resolver stator 5 is fixed on the ring-type convex of described stator case 1, turns hub 3 and is provided with outstanding ring-type convex, and rotary transformer rotor 6 is fixed on and described turns on the ring-type convex of hub 3;
The inwall of stator case 1 is provided with water channel 11, and in water channel water channel 11, circulation cooling fluid is to take away heat.
In the present embodiment, the heat-conducting insulation material that in the gap between stator case 1 and stator 2, (i.e. region shown in B in Fig. 1) embedding density is little is to improve radiating efficiency; The conductive coefficient 0.03W/mK of air, can to reach 3W/mK ~ 5W/mK even higher for the conductive coefficient of heat-conducting insulation material herein.
