Technical field

The utility model belongs to mechanical equipment component field, more particularly to a kind of for the dynamic of hybrid vehicle Power unit.

Background technique

Serious with environmental pollution, many companies begin to respond to the environmentally friendly slogan such as low-carbon energy-saving, and hybrid power development is fast Speed.Initial stage is generally and carries engine, the hybrid vehicle of generator and motor occurs starting with advances in technology The hybrid vehicle of machine and reversible electric machine.In the hybrid vehicle, it can be carried out using engine driving reversible electric machine Power generation charges to battery, or is charged the battery by exterior power supply, passes through motor-driven vehicle row after charging complete It sails.Generator and the independent hybrid power of motor, in vehicle travel process, motor is held as power drive vehicle, engine Continuous drawing generator supplements electricity to battery, and engine continuous works under economical consumption of fuel state, because engine is with certain Load operation, so can restrain the discharge of harmful substance, fuel economy is improved.

Other than the traveling of the HV mode travelled as common hybrid vehicle as described above, there is also With make engine, motor alternately as driving hybrid vehicle.In such hybrid vehicle, in urban area Etc. engine stop can be made as electric automobile during traveling relatively long distance, can be gone as the vehicle for not generating exhaust It sails.

Utility model content

The purpose of this utility model is time in order to realize hybrid vehicle excess energy under engine drive mode It receives；It is superimposed by the torque of engine and motor simultaneously to realize that puffer replaces the purpose of big engine；It solves simultaneously Hybrid power system drive assembly axial length is too long, causes difficult arrangement even the problem of can not arranging, proposes a kind of new Hybrid power connection method improves transmission chain and is mechanically connected reliability, and it is integrated to can be improved hybrid power system drive assembly Degree, reduces hybrid power system drive assembly length.

Specific technical solution is as follows:

A kind of power unit for hybrid vehicle, according to different duty requirements, by controlling electromagnetic clutch On-off, engine start-stop and disc type reversible electric machine operating mode, export three kinds of different dynamic modes；The disc type is reversible Motor is installed on engine by bell housing seam allowance；Disc type reversible electric machine rotor rear end connects power and passes as power output shaft Moving cell (oil pump, gear-box etc.)；The electromagnetic clutch stator is installed on engine end face, and stator is installed on the reversible electricity of disc type Machine rotor leading portion.

Further, it works in the environment of allowing engine operation, and required power is less than engine output When, the electromagnetic clutch obtains electric actuation, the rotation of driven by engine disc type reversible electric machine, and reversible electric machine is in generating state, passes through It crosses electric machine controller to charge the battery, engine excess energy is recycled, while disc type reversible electric machine rotor linkage gear unit It works；It works in the environment of not allowing using engine, such as completely enclosed space, grottoes, inflammable explosive article warehouse Deng electromagnetic clutch power-off separates engine with disc type reversible electric machine, and disc type reversible electric machine is in motoring condition, passes through Electric machine controller is powered it, and dragging gear unit works；It works in the environment of allowing using engine, and When required power is greater than engine output, such as road conditions when climbing, muddy road, the electromagnetic clutch obtain electric actuation, Disc type reversible electric machine is in motoring condition, is powered through electric machine controller to it, and engine output is the same as the reversible electricity of disc type Machine output power is overlapped, and rotor linkage gear unit works.

Further, engine, electromagnetic clutch, disc type reversible electric machine and gear unit are coaxially connected, electromagnetic clutch Device is connected to engine by engine end face seam allowance, engine crankshaft, and disc type reversible electric machine is through the joint of the seam allowance in engine Bell housing, gear unit is through the joint of the seam allowance in disc type reversible electric machine rotor.

Further, the clutch of engine and disc type reversible electric machine is realized by electromagnetic clutch opening and closing, is being sent out When motivation and disc type reversible electric machine are overlapped, the work of electromagnetic clutch friction plate is avoided because of engine and the reversible electricity of disc type Machine revolving speed mismatches the damage for causing system.

The utility model has the advantages that

1. a kind of power unit for hybrid vehicle, using after hybrid power can by averagely need to power come really The maximum power for determining engine is now under the optimum operating condition that oil consumption is low, pollution is few and works.

2. a kind of power unit for hybrid vehicle, when needing high-power or engine power insufficient, by disk The battery of formula reversible electric machine supplements；When load is few, power more than needed can generate electricity and charge the battery, due to the sustainable work of engine Make, battery can be continuously available charging again, improve the utilization rate of the energy.

3. the battery of a kind of power unit for hybrid vehicle, disc type reversible electric machine can be recycled very easily Energy when braking, when descending, when idling；In bustling urban district, engine can be shut down, the electric energy list stored by disc type reversible electric machine " zero " discharge is realized in solely driving.
