Description of drawings
Fig. 1 is the structural representation of the utility model;
The structural representation that Fig. 2 is connected with automobile brake power-assisted vacuum pump through electric control clutch for the utility model engine accessory power rating.
Among the figure: 1, mono-directional overrun crank pulley outer ring, 2, mono-directional overrun crank pulley inner ring, 3, Idle wheel; 4, generator pulley, 5, power-assisted steering pump belt pulley, 6, the engine water pump belt pulley; 7, air condition compressor belt pulley, 8, poly Vbelt, 9, engine crankshaft; 10, generator, 11, electric control clutch, 12, vacuum pump.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of hybrid power engine accessory drive system; Comprise the mono-directional overrun crank pulley, Idle wheel 3, generator pulley 4, power-assisted steering pump belt pulley 5, engine water pump belt pulley 6 and the air condition compressor belt pulley 7 that connect successively through poly Vbelt; The outer ring 1 of said mono-directional overrun crank pulley is connected with above-mentioned engine accessory power rating, and the inner ring 2 and the engine crankshaft 9 of said mono-directional overrun crank pulley are rigidly connected.
When the motor proper functioning, the mono-directional overrun crank pulley is in bonding state, by the engine-driving annex; When engine shutdown, the mono-directional overrun crank pulley is in separated state, by the engine-driving annex.
The working principle of the utility model:
The difference in use of orthodox car motor and hybrid power engine:
The orthodox car motor is in running state all the time in driving procedure; Have only part operating mode motor to be in the oil-break state, though the motor oil-break, motor still keeps certain rotating speed operation; So as far as orthodox car; Engine accessory power rating is in running state all the time, is that annex provides power through engine crankshaft belt pulley, ensures the realization of the required various functions of automobile.
The hybrid vehicle then working state with traditional motor car engine is different, and in the mixed power, there is shutdown mode in motor; In this state, motor and annex all will quit work, and can not realize the various function requirements of conventional vehicles; The measure that present mixed power is taked annex is: the engine accessory power rating motorized; Air-conditioning for example, water pump etc., the employing of these measures; Certainly will increase corresponding cost and complexity, the inheritance missionary society of former engine accessory power rating is brought such as many problems such as cost raising, reliability reduction, the increases of maintaining workload.
For addressing the above problem; The utility model provides above-mentioned hybrid power engine accessory drive system; Existing working principle with above-mentioned hybrid power engine accessory drive system is narrated as follows: the mono-directional overrun crank pulley is transmitting torque in one direction; When motor normally moved, the mono-directional overrun crank pulley was in bonding state, and annex that engine-driving is with turns round; For servosteering, engine cooling water pump, air-conditioning, generator etc. provide power, identical with the driving mode of traditional vehicle; When motor was in outage state, the mono-directional overrun crank pulley was in separated state, and generator becomes motor drives annex individual operation, and at this moment, engine crankshaft remains static.This model utility is utilized the characteristic of mono-directional overrun crank pulley unidirectional delivery torsion, during engine shutdown, through the mono-directional overrun crank pulley engine crankshaft is isolated, and has solved the problem of accessory drive in the engine shutdown state.Owing to can use the generator drive engine accessory power rating, make the original annex of motor under two kinds of mode condition, to work, and will hybrid power engine annex motorized.
The degree of vacuum problem, automobile brake adopts the vacuum servo mode, increases Braking efficiency; Its degree of vacuum is taken from engine intake manifold, and when engine shutdown, engine intake manifold can not provide corresponding degree of vacuum; Under this pattern; Obtaining degree of vacuum has two kinds of approach, and a kind of is to adopt electricity to drive vacuum pump, and a kind of in addition is to utilize engine accessory power rating to drive vacuum pump.When utilizing engine accessory power rating to drive vacuum pump; Between annex and the vacuum pump electric control clutch need be housed, see also Fig. 2, generator pulley 4, generator 10 and electric control clutch 11 are connected through generator shaft successively; Vacuum pump 12 is connected with motor shaft through electric control clutch 11; When the motor proper functioning, electric control clutch breaks off, and degree of vacuum is taken from engine intake manifold; When motor was in outage state, electric control clutch 11 started or stoped vacuum pump as required, guaranteed automobile brake vacuum servo ability proper functioning; Similar diesel generator band vacuum pump arrangement, the diesel generator rear end connects vacuum pump, during the vacuum pump high speed operation; That motor is that vacuum pump provides is lubricated, sealing and cooling are oily with pressure lubrication; With DENG institute difference, can select the self-lubricating vacuum pump for use through using electric control clutch, cancellation pressure lubrication oil oil pipe.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
