Description
Technical field
The present invention relates to vehicle temperature control apparatus of transmission oil of---especially motor vehicle---.The invention still further relates to the corresponding vehicle of outfit and the temperature controlled method of transmission for vehicles oil.
Background technique
Speed changer defines a part for vehicle driveline.Be placed in speed changer between motor and driving wheel for controlling the ratio between engine speed and each rotating speed of driving wheel.Except single speed or hand shift multi-speed transmission, also there is the multi-speed transmission with automation mechanized operation.The type of the automatic transmission automatic transmission from semi-automatic transmission to torque-converters is to continuously variable transmission.Manual and automatic transmission can combine with such as motor and/or explosive motor.
Each assembly of speed changer manufactures in the mode that can make them and engage in an ideal way in given temperature range.In the process of operation, along with the temperature of the increase speed changer of load and rotating speed also rises, the transmission oil be positioned at wherein should be cooled, the cooling in automatic transmission casing should be noted especially.For such object, speed changer can be connected to fluid communication on air/oil or water/oil heat exchanger.Water/oil heat exchanger is used for transmitting heat between the coolant circuit and transmission oil of internal-combustion engine, and the heat energy of transmission oil can disperse in surrounding atmosphere by air/oil heat exchanger.
Conversely, the speed changer of temperature below described temperature range can increase friction, except increasing wearing and tearing, also cause high energy or fuel consumption.This causes effort transmission oil and then speed changer itself being heated to operating temperature within the as far as possible short time.But, compared with explosive motor, owing to lacking ignition heat, speed changer and need the more time to heat.Become known for the device and method of the oil of heating transmission as quickly as possible in the prior art.Such as, by utilizing electric heater or specific engine thermal transmission to produce heating.Because the energy needed for such object finally must such as be produced by explosive motor, the reason for energy can not have actual effective operation in this case.
Such as, DE4104093A1 proposes the temperature control apparatus of the vehicle with explosive motor.This device comprises main cooling circuit, and its form is the first coolant circuit and further second coolant circuit.First coolant circuit is used for explosive motor fluid communication to be connected to heat exchanger.The form of this heat exchanger is air/coolant heat exchanger, and it is for the freezing mixture of cool stream through explosive motor.By contrast, the second coolant circuit is used for for extra heat exchanger and Intermediate Heat Exchanger provide the connection of fluid communication among other things.In this case, the form of extra heat exchanger is air/coolant heat exchanger, and it is for the freezing mixture of cool cycles at the second coolant circuit.By contrast, the form of Intermediate Heat Exchanger is oil/coolant heat exchanger, thus makes it for cooling the speed changer being connected to internal-combustion engine.For this purpose, freezing mixture and transmission oil all flow through extra heat exchanger.There is provided connecting pipeline further, two coolant circuits connect to fluid communication by request.
Due to the first coolant circuit experience rapid heating, this heat also can be supplied to the second coolant circuit by connecting pipeline.For this purpose, among other things, also provide thermal accumulator herein, thermal accumulator is connected with the first coolant circuit fluid flow communication, and it contributes to rapid heating.In this way, although the heat energy being especially fed to the first coolant circuit when cold start-up by thermal accumulator can pass through connecting pipeline,---free skew---is delivered to forward the second coolant circuit.Therefore, the heat energy of thermal accumulator is finally also fed to the additional heat exchange device for transmission oil at least in part.The unnecessary heat energy produced at the first coolant circuit can be used further to subsequently as thermal accumulator accumulation of heat.
Because the heat exchanger of transmission oil is connected to one of coolant circuit, transmission oil and then speed changer itself only can heat at leisure.Especially, this is that this takes at least part of heat energy away from freezing mixture due to the long distance on the path of thermal accumulator and speed changer and many assemblies.And the heating of whole system finally depends on explosive motor, only allow partly efficient operation for heating transmission.
Due to like this, it seems at present and can not obtain more favourable energy balance.Even if because explosive motor is not used in the direct or indirect source as rapid heating speed changer, so extra electric heating source is unfavorable for the balance of energy equally.Therefore temperature control apparatus known today and their operation provide further room for improvement undoubtedly.

It should be noted that the feature of specifying respectively in the following description and measure can be bonded to each other in any required, technically useful mode and show further configuration of the present invention.The description of this invention additionally characterizes especially by reference to the accompanying drawings and describes the present invention in detail.
The following detailed description of a kind of according to the temperature control apparatus for transmission for vehicles oil of the present invention, be particularly useful for manual transmission or the automatic transmission of motor vehicle.For such object, temperature control apparatus comprises at least one heat exchanger.There is provided heat exchanger for fluid communication transmission for vehicles can be connected to by speed changer oil circuit.According to the present invention, temperature control apparatus also comprises at least one thermal accumulator.Be connected on speed changer oil circuit to described thermal accumulator fluid communication.In this arrangement, thermal accumulator is configured for accumulation and within a period of time, therefore stores the heat energy coming from transmission oil at least partly.Thermal accumulator is also configured for and the previously stored heat energy coming from transmission oil is returned to transmission oil at least partly.
In addition, control gear is placed in speed changer oil circuit.Described control gear is configured for and the transmission oil of the oil circuit Inner eycle of speed changer is directed to heat exchanger and/or thermal accumulator at least partly.More or fully transmission oil can be fed to heat exchanger and thermal accumulator according to demand in this way.Therefore, due to control gear, the oil of speed changer flows through speed changer oil circuit in a specific way, and in particular through heat exchanger and thermal accumulator.In this process, the specific control setting of control gear is the target based on obtaining: effective accumulation of the rapid heating of transmission oil and/or the unnecessary heat energy from transmission oil.
Speed changer oil circuit is subdivided at least two loops by control gear.In other words, only can a circulation in these two loops at the transmission oil of speed changer oil circuit Inner eycle, or circulate in two loops with partial amount simultaneously.Particularly preferably, speed changer oil circuit can be subdivided into thermal accumulator loop and cooling circuit.
In this case, in corresponding one that heat exchanger and thermal accumulator are placed in these two cooling circuits.Therefore, thermal accumulator is placed in the thermal accumulator loop of speed changer oil circuit, and heat exchanger is placed in the cooling circuit of speed changer oil circuit.
By the favourable arrangement of direct thermal accumulator in speed changer oil circuit, now can by being absorbed the waste heat of speed changer in transmission operating by warmed-up transmission oil.In this respect, existing solution does not provide the direct absorption of heat energy, and these heat energy under any circumstance all must dissipate.Conversely, in order to obtain the cooling of speed changer, made the trial for the purpose of being removed as quickly as possible by the heat energy from transmission oil road by heat exchanger before.Herein, in fact at least part of heat energy is converted to advantage by being temporarily stored in thermal accumulator by the present invention, otherwise this heat will be dissipated.
Due to the operation heating of this heat energy source in speed changer inherence, this under any circumstance all needs, and extracting heat energy from speed changer oil circuit can not have impact to energy balance at first.Conversely, energy balance is restored to transmission oil at the heat energy accumulated before and then is significantly improved to during speed changer sometimes.Therefore, the friction in speed changer and resistance die down in a short period of time, and then reduce energy ezpenditure especially fuel consume.
In the context of the present invention, thermal accumulator is interpreted as the assembly that can absorb heat energy and release heat energy as required.Such as, this assembly can be but be not limited to chemical heat accumulator.
Herein, lay special stress on, according to the heat exchanger apparatus in speed changer oil circuit of the present invention, provides significant advantage compared with the device being sometimes referred to as in the cooling circuit of explosive motor of this device and routine.
Chemical heat accumulator generally acknowledges the general disadvantage with low rate of heat release.For this reason, chemical heat accumulator starts to seem to be not suitable for explosive motor or combustion engine.In contrast, if such as directly provide deep fat in engine oil path, the rate of heat release of " oily thermal accumulator " can be significantly higher.But the energy stored by chemical heat accumulator is discharged by chemical reaction, this energy is dissipated in oil subsequently.For the thermal accumulator of the size be applicable in motor vehicle, therefore this rate of heat release is usually less than oily thermal accumulator.On the other hand, the heat energy be stored can be considered as roughly equal for the system of chemical heat accumulator and oily thermal accumulator.Therefore in possible configuration, chemical heat accumulator is favourable useful for speed changer, and first because speed changer thermal mass is less than the thermal mass of internal-combustion engine, secondly, speed changer is significantly longer than in the preheating of motor usually.
Because compared with the preheating energy needed for explosive motor, the heat energy of suitable thermal accumulator is usually relatively low, can expect and little temperature can only be had to increase.In this context, because speed changer has lower thermal inertia compared with explosive motor or combustion engine, the heating of speed changer is more conducive to the heating of explosive motor significantly.Therefore this makes the increase of the temperature of speed changer compared with explosive motor significantly higher.Only have and could realize a large amount of energy conservations when cold start-up by this way, especially fuel oil saving.Therefore thermal accumulator can be the form of chemical heat accumulator.Self-evident, thermal accumulator also can be the form of oily thermal accumulator.
Especially preferably, control gear comprises at least one valve or control valve unit, can the guiding of the transmission oil relevant with path to the direction of transmission oil in controlled variator oil circuit by this device.For such object, valve or control valve unit have at least one control position, itself or allow or do not allow transmission oil to flow through thermal accumulator.Preferably at least provide two control positions, transmission oil is conducted through heat exchanger a control position and is directed into thermal accumulator in another position, and this depends on the temperature of transmission oil at each occurrence.
Therefore, temperature below variator operating temperature and therefore can regard as colder transmission oil preferably can not flow through heat exchanger before entering speed changer but arrive thermal accumulator.By this way, the heat energy that it is accumulated before absorbing from thermal accumulator, transfers to the parts that each flows into subsequently at least partly in speed changer.
Under contrast, higher than variator operating temperature and therefore regard as hotter transmission oil and preferably conduct to thermal accumulator.In this case, before turning back to speed changer, transmission oil can be conducted through heat exchanger before or after by thermal accumulator.By this way, the transmission oil of heat is cooled, and especially by heat exchanger simultaneously also by thermal accumulator, certain thermal accumulator also obtains heat energy from transmission oil.By this way, the transmission oil cooled down can absorb heat energy when entering speed changer from flowed into transmission assembly subsequently again, and therefore these assemblies and speed changer are integrally cooled.
The invention provides the favourable layout of control gear, it can be preferably located in the upstream of heat exchanger.In this case, first the part leaving the transmission oil of speed changer flows through control gear, and it predefines the path subsequently of transmission oil.According to the temperature of transmission oil, itself or be transmitted to heat exchanger or all arrive to thermal accumulator or the two.
Thermal accumulator should be preferably designed for the cooling capacity being used in the energy and heat exchanger that fill thermal regenerator device and match.By this way, the filling heat and will have seldom gearbox oil temperature or not impact of thermal accumulator.Can greatly be simplified thus by the control of control gear.
Therefore, the neutral position for control gear can be had in principle, thus transmission oil can be conducted through heat exchanger simultaneously and arrive thermal accumulator.Each through-flow amount also can be controlled by control gear thus obtain the adjustment of the transmission oil of the circulation optimized as far as possible.
In improving at one of the present invention, it is contemplated that the heat exchanger for cooling transmission oil can be configured to air/oil heat exchanger.In this way, do not have further system due to the waste heat of transmission oil pressurized.If the unnecessary heat energy of transmission oil also dissipates thus---not in thermal accumulator---in surrounding atmosphere.
As above illustrate according to temperature control apparatus of the present invention, although there is the extra thermal source of the thermal accumulator form for transmission oil, its can realize obtain improve energy balance.Because heat energy to be accumulated to absorb from transmission oil and accumulates producing almost consistent position with heat energy, after vehicle short-term operation, thermal accumulator has reached maximum accumulation of heat.And, because transmission oil preferably not long ago absorbs heat energy from thermal accumulator what enter speed changer, thermal accumulator to the direct vicinity of speed changer make possibly fast or at least auxiliary heating to operating temperature.Because the heat produced in transmission operating under any circumstance all must dissipate when exceeding given temperature, therefore can in a way, come favourable to utilize this heat by time migration.Therefore according to the configuration of heat exchanger, even if when cold start-up, enough energy are also had to can be used for making transmission oil and then speed changer itself arrive operating temperature as quickly as possible in operation.
Certainly, should should be mentioned that thermal accumulator must accumulation of heat thus make it fundamentally can absorb and then store the heat of transmission oil further.For this purpose, the transmission oil of heat is fed to thermal accumulator, and it can be realized by the suitable activation of control gear.In this case, the heat exchanger in the cooling circuit of speed changer oil circuit can be got around, thus make the oil of in fact uncooled speed changer arrive thermal accumulator.In this case, in desirable configuration, the ability that regulation thermal accumulator has the storage heat identical with the ability of the heat exchanger for cooling transmission oil is useful.In other words, when thermal accumulator is had to by accumulation of heat, transmission oil is cooled (as already mentioned) to a certain extent in thermal accumulator.Therefore also to guarantee that the temperature of the transmission oil when thermal accumulator accumulation of heat can not become too high simultaneously.Once thermal accumulator accumulation of heat, control gear is properly activated thus transmission oil is again directed in heat exchanger.
The present invention also relates to a kind of vehicle, this vehicle also has the temperature control apparatus of the transmission oil for speed changer except drive motor and the speed changer that couples to moment of torsion transmission with it.In particular, temperature control apparatus can be temperature control apparatus as previously described.Such as, drive motor can be power-actuated.But drive motor also can be explosive motor.
The invention further relates to a kind of method of the temperature of the transmission oil of---especially motor vehicle---for controlling vehicle, temperature controls to be implemented by suitable temperature control apparatus.In particular, such temperature control apparatus can be temperature control apparatus described above.
For such object, in order to make transmission oil cool, it is connected to the speed changer oil circuit conduction of speed changer by fluid communication and is arrived heat exchanger.According to the present invention, transmission oil conducted to thermal accumulator before or after flowing through heat exchanger.Thus achieve heat energy at least partially extract from transmission oil and time be accumulated in thermal accumulator.
Invention further provides the control gear be placed in speed changer oil circuit.Prepare control gear thus enable transmission oil conduct to heat exchanger and/or thermal accumulator at least in part according to their temperature.
Speed changer oil circuit is subdivided into thermal accumulator loop and cooling circuit by control gear.By this way, according to the specific control position of control gear, the oil of at least part of speed changer can be conducted by thermal accumulator loop and/or cooling circuit.
Consequent favourable part has done relevant concrete elaboration, so with reference to explanation above in conjunction with previously described temperature control apparatus according to the present invention.And, this be also applicable to after the further favourable configuration according to method of the present invention that describes, and the vehicle with such temperature control apparatus illustrated above.
In a favourable improvement, in order to the oil of heating transmission, define transmission oil and can first conduct to thermal accumulator then to speed changer.By this way, can be transmitted back in transmission oil at least partially in accumulated heat energy previous in thermal accumulator.

Embodiment
In general, in different drawings, identical part uses the same reference numerals to represent, so usually only describe once.
Fig. 1 schematically presents according to temperature control apparatus 1 of the present invention.Temperature control apparatus 1 is for controlling the temperature of the oil 2 of vehicle (not shown in detail) speed changer.For this purpose, temperature control apparatus 1 comprises heat exchanger 3.Can also see the speed changer 4 of vehicle (not shown), it can be connected to heat exchanger 3 to fluid communication by speed changer oil circuit 5.
With reference to the diagram in Fig. 1, the thermal accumulator 6 being connected to fluid communication speed changer oil circuit 5 is placed in right side.It can also be seen that the control gear 7 in the speed changer oil circuit 5 of the upstream being placed in heat exchanger 3.
Control gear 7 is configured for and the transmission oil 2 at speed changer oil circuit 5 Inner eycle is conducted to heat exchanger 3 and/or thermal accumulator 6 at least partly, as described further below.
Fig. 2 shows the first control position A of control gear 7.In this case, speed changer oil circuit 5 is reduced to thermal accumulator loop 8.In this example current, thermal accumulator loop 8 is by continuous print wire tag, and the residual circuit of speed changer oil circuit 5 shows by a dotted line.Can find out, at the first control position A, transmission oil 2 flows through thermal accumulator loop 8 in the following way, and first the transmission oil 2 from speed changer 4 conducts to control gear 7 and then directly arrive thermal accumulator 6.
Prepare due to thermal accumulator 6 and be used for the previous heat energy stored from transmission oil 2 to be at least partly transported in transmission oil 2 at least in part, heated when the oil 2 of speed changer flowed through thermal accumulator 6 before turning back to speed changer 4.In this way, the auxiliary heating accelerating speed changer in particular at least partly.
Fig. 3 shows the second control position B of control gear 7.Such position is adopted when transmission oil has exceeded preset temperature.For such object, such as temperature transducer (not specifically illustrating) can be placed in speed changer oil circuit, thus for control gear provide about the temperature of transmission oil information or control its control position A, B.At the second control position B, speed changer oil circuit 5 is reduced to cooling oil path 9.
In current example, cooling circuit 9 is by continuous print wire tag, and the residual circuit of speed changer oil circuit 5 shows by a dotted line.Can find out, at the second control position B, transmission oil 2 flows through cooling circuit 9 as follows, and the transmission oil 2 from speed changer 4 is directly conducted to heat exchanger 3.The form of heat exchanger 3 is air/oil heat exchanger, thus the unnecessary heat energy from transmission oil 2 can be dissipated in ambient air by heat exchanger 3.After flowing through heat exchanger 3, the oil 2 of speed changer gets around the direct conduction of thermal accumulator 6 subsequently and gets back to speed changer 4.Herein, first the cooling of the oil 2 of speed changer occurs, and thermal accumulator 6 is accumulation of heat completely.
The Fig. 1 described in detail therefore illustrates the first control position of the control gear 7 in Fig. 2 and Fig. 3 and the mixed form of second control position A, B and with the relevant loop of the form of thermal accumulator loop 8 and cooling circuit 9.Herein, the oil 2 of speed changer has reached the temperature needing cooling, and control gear 7 has moved on to the 3rd control position C for this purpose, is conducted through both heat exchanger 3 and thermal accumulator 6 at the oil 2 of this position speed changer.Along with the generation of this situation, transmission oil 2 is cooled by heat exchanger 3 and thermal accumulator 6, and thermal accumulator 6 extracts and accumulation heat energy from transmission oil 2.
In addition, if transmission oil has reached corresponding temperature, may be used for for thermal accumulator 6 accumulation of heat according to the configuration in Fig. 2.In this case, if thermal accumulator 6 identical with heat exchanger 3 capacity be favourable, thus transmission oil is cooled in thermal accumulator 6 in some degree.Therefore on the other hand, this operating position by thermal accumulator 6 heating transmission oil, thus can decrease warm-up phase.On the other hand, may be used for for thermal accumulator 6 accumulation of heat according to the operating position of Fig. 2.But once the abundant accumulation of heat of thermal accumulator, control gear 7 should activate thus allow that transmission oil flows through heat exchanger 3 again.Therefore provide according to the operating position of Fig. 2 for the oil---such as at the warm-up phase of explosive motor---of heating transmission and be thermal accumulator 6 only temporarily (namely within very short time period often) " accumulation of heat ".
