[0050] 如图1-图12所示,电机动力轴3设置成可与输入轴中的一个(例如,第二输入轴12)进行联动。 [0050] As shown in FIG 1 to FIG 12, the motor may be provided to the power shaft 3 (e.g., the second input shaft 12) is linked with the input shaft of a. 换言之,来自该输入轴的动力在需要向电机动力轴3传递时,电机动力轴3则与该输入轴联动以传输动力,或者来自该电机动力轴3的动力在需要向该输入轴传递时,该输入轴则与电机动力轴3联动以传输动力。 In other words, the power from the input shaft is transmitted to the motor requiring a power shaft 3, the motor power shaft 3 in conjunction with the input shaft to transmit power from the motor power or the power shaft 3 in the time required to transfer the input shaft, the power input shaft is the motor shaft 3 with the linkage to transmit power.

[0051] 简言之,在具有根据本发明实施例的动力传动系统100的车辆处于某些工况时(具体工况将在下面结合具体的实施例进行详述),且动力需要在电机动力轴3与该输入轴之间进行传递时,则该输入轴与电机动力轴3进行联动。 [0051] Briefly, when a vehicle is in a drive system 100 according to certain operating conditions of the present invention, embodiments of the power (the specific conditions in connection with specific embodiments described in detail below), and the power necessary to power the motor when the shaft 3 is transmitted between the input shaft with the input shaft and the motor power shaft 3 linkage.

[0052] 需要说明的是,上述的“联动”可以理解为多个部件(例如,两个)关联运动,以两个部件联动为例,在其中一个部件运动时,另一个部件也随之运动。 [0052] Incidentally, the aforementioned "interaction" can be understood as a plurality of members (e.g., two) associated with the motion to two interlocking parts, for example, when one of the moving member, the other also will be moving member .

[0053] 例如,在本发明的一些实施例中,齿轮与轴联动可以理解为是在齿轮旋转时、与其联动的轴也将旋转,或者在该轴旋转时、与其联动的齿轮也将旋转。 [0053] For example, in some embodiments of the present invention, the gear-axis can be understood as when the gear rotates, its linkage shaft will also rotate, or rotates the shaft, with its linkage gear will also rotate.

[0054] 又如,轴与轴联动可以理解为是在其中一根轴旋转时、与其联动的另一根轴也将旋转。 [0054] In another example, the shaft-axis can be understood as a time axis, and its other axis will also rotate the linkage therein.

[0055] 再如,齿轮与齿轮联动可以理解为是在其中一个齿轮旋转时、与其联动的另一个齿轮也将旋转。 [0055] Again, with the gear linkage as will be understood when one gear is rotated, the other also will be interlocked with the gear rotation.

[0056] 在本发明下面有关“联动”的描述中,如果没有特殊说明,均作此理解。 [0056] In the description of the "linkage" following the present invention, unless otherwise stated, are understood to have.

[0057] 类似地,第一电动发电机51设置成能够与电机动力轴3联动。 [0057] Similarly, the first motor generator 51 can be provided to the power shaft 3 in conjunction with the motor. 例如,第一电动发电机51在作为电动机工作时,可将产生的动力输出给电机动力轴3。 For example, the power of the first motor generator 51 as a motor, can generate an output power to the motor shaft 3. 又如,在第一电动发电机51作为发电机工作时,来自电机动力轴3的动力可以输出至第一电动发电机51,从而驱动第一电动发电机51进行发电。 As another example, when the first motor generator 51 as a generator, the power from the motor power shaft 3 can be output to the first motor generator 51, thereby driving the first motor generator 51 generates electric power.

[0058] 这里,需要说明一点,在本发明有关“电动发电机”的描述中,如果没有特殊说明,该电动发电机可以理解为是具有发电机与电动机功能的电机。 [0058] Here, it is described that, in the description of "electric generator" of the present invention, unless otherwise stated, the motor generator may be understood as a generator and a motor having a motor function.

[0059] 如上,电机动力轴3可以与输入轴中的一个进行联动,特别地,在电机动力轴3与该输入轴中的一个进行联动时,第一电动发电机51能够利用来自发动机4输出的至少部分动力在车辆行驶以及驻车时进行发电。 [0059] As the motor power shaft 3 can be linked with the input shaft in a, in particular, the power shaft 3 when the motor linkage with the input shaft of a first motor generator 51 can use the output from the engine 4 the power to generate electricity at least part of the vehicle is running and parked.

[0060] 换言之,在车辆处于行驶状态且电机动力轴3与该输入轴中的一个进行联动时,发动机4的至少部分动力可以通过电机动力轴3输出至第一电动发电机51,从而驱动第一电动发电机51进行发电,实现发动机4边驱动边充电工况。 [0060] In other words, when the vehicle is traveling and the linkage with the input shaft of one, at least a portion of the power of the engine 4 can output power shaft 3 through the motor shaft 3 to the first motor power generator motor 51, thereby driving the first an electric generator 51 generates electric power, to achieve the engine-side driver 4 while charging conditions. 而在车辆处于驻车(车辆停止但发动机4仍处于工作状态)状态且电机动力轴3与该输入轴中的一个进行联动时,发动机4的至少部分动力可以通过电机动力轴3输出至第一电动发电机51,从而驱动第一电动发电机51进行发电,实现驻车充电功能(即“停车”充电)。 And when the vehicle is in a vehicle (the vehicle is stopped, but the engine is still in operation 4) the power state and the motor shaft 3 in conjunction with the input shaft of one engine 4 may be at least partially powered by the power output of the motor to the first shaft 3 the motor generator 51, thereby driving the first motor generator 51 generates electric power, to achieve a parking charging function (i.e., "parking" charging).

[0061] 进一步,电机动力轴3还设置成可与输出轴中的一个(例如,第二输出轴22)联动。 [0061] Further, motor power shaft 3 is further provided with an output shaft (e.g., the second output shaft 22) linkage. 例如,来自电机动力轴3的动力在需要向该输出轴传递时,电机动力轴3则与该输出轴联动以传输动力。 For example, power from the motor shaft 3 when the power needs to be passed to the output shaft, the motor shaft 3 linked to the power transmission shaft and the output power. 特别地,在电机动力轴3与输出轴中的一个进行联动时、第一电动发电机51能够将产生的动力通过输出轴的一个输出,从而驱动车辆行驶。 In particular, the power shaft 3 when the motor linkage and the output shaft in a power of the first motor generator 51 can be produced by an output shaft, thereby driving the vehicle. 简言之,在电机动力轴3与该输出轴联动时,第一电动发电机51是可以作为电动机并输出动力以驱动车辆行驶的。 Briefly, when the motor shaft power in conjunction with the output shaft 3, the first motor generator 51 as a motor and can output power to drive the vehicle is traveling.

[0062] 需要说明一点,在本发明的描述中,电机动力轴3可以是第一电动发电机51自身的电机轴。 [0062] Note that, in the description of the present invention, the motor power shaft 3 may be a first motor generator of the motor shaft 51 itself. 当然,可以理解的是,电机动力轴3与第一电动发电机51的电机轴也可以是两个单独的轴。 Of course, it is appreciated that the motor power shaft 3 with the motor shaft of the first motor generator 51 may be two separate axes.

[0063] 由此,根据本发明实施例的动力传动系统100,能够在车辆行驶以及驻车时实现充电功能,丰富了充电模式,至少在一定程度上解决了现有动力传动系统充电方式单一、充电效率低等问题。 [0063] Thus, according to the present invention, the power transmission system embodiment 100 of the embodiment, it is possible to achieve vehicle traveling, and the charging function is parked, the rich charge mode, solves at least some extent, the power transmission system in a single charging mode, charging low efficiency. 简言之,根据本发明实施例的动力传动系统100能够实现行车充电和驻车充电两类充电模式。 Briefly, according to the present invention, the power transmission system embodiment 100 of the embodiment can realize a parking charge and the charging driving two charging mode.

[0064] 下面参照图1且结合图2-图12对变速器的具体构造结合具体的实施例进行详细描述。 [0064] Referring now to FIG. 1 and FIG. 2 to FIG. 12 in conjunction with the transmission specific configuration in conjunction with the specific embodiments described in detail.

[0065] 首先对电机动力轴3上的电机动力轴同步器33c、电机动力轴第一齿轮31和电机动力轴第二齿轮32进行详细描述。 [0065] First, the power shaft of the motor on the synchronous motor 3 power shaft 33c, a first motor power shaft gear 31 and second gear 32 is described in detail motor power shaft.

[0066] 具体而言,电机动力轴第一齿轮31和电机动力轴第二齿轮32均空套设置在电机动力轴3上,也就是说,电机动力轴3与电机动力轴第一齿轮31能够差速转动,类似地,电机动力轴3与电机动力轴第二齿轮32也能够差速转动。 [0066] Specifically, the motor gear 31 and the power shaft of the first motor power shaft of the second gear 32 are disposed on the idler shaft 3 motor power, that is, the motor power and motor power shaft 3 can be a first gear shaft 31 differential rotation, similarly, the motor power shaft 332 can be rotated in the differential gear shaft of the second motor power.

[0067] 如图1并可结合图2-图12,电机动力轴第一齿轮31设置成与输入轴的一个进行联动,电机动力轴第二齿轮32设置成与输出轴的一个进行联动。 [0067] FIG 1 in conjunction with FIGS. 2 and 12, the first motor power shaft gear 31 is provided with the input shaft of a linkage, a motor power shaft second gear to the output shaft 32 is provided a linkage. 在图1-图12的一些示例中,电机动力轴第一齿轮31是与第二输入轴12联动的,电机动力轴第二齿轮32是与第二输出轴22联动的,但本发明并不限于此。 In some examples, FIGS. 12, a first motor power shaft gear 31 is linked with the second input shaft 12, the motor 32 is the power shaft of the second gear and the output shaft of the second linkage 22, but the present invention is not limited to this.

[0068] 进一步,电机动力轴同步器33c设置在电机动力轴第一齿轮31和电机动力轴第二齿轮32之间,电机动力轴同步器33c的接合套可沿电机动力轴3的轴向运动,例如在图1-图12的示例中,电机动力轴同步器33c的接合套可以在拨叉机构的驱动下沿电机动力轴3的轴向向左或向右运动。 [0068] Further, the motor shaft power synchronizer motor power shaft 33c provided on the first gear 31 and between 32, 33c engaging motor power synchronizer sleeve shaft axially movable along the second gear shaft motor power motor power shaft 3 , for example, in the example of FIG. 1 to FIG. 12, the motor shaft power synchronizer sleeve 33c of the motor can be moved axially left or right power shaft driven by movement of the fork means 3.

[0069] 电机动力轴同步器33c由于设置在电机动力轴第一齿轮31与电机动力轴第二齿轮32之间,因此电机动力轴同步器33c能够选择性地将电机动力轴第一齿轮31与电机动力轴第二齿轮32之一与电机动力轴3接合。 [0069] Motor power shaft 33c due to the synchronizer 32 is disposed between the power shaft of the first motor 31 and the gear motor power shaft of the second gear so that the motor power shaft 33c synchronizer can selectively power the motor shaft and the first gear 31 one motor power shaft gear 32 and the second motor power shaft 3 engages.

[0070] 结合图1-图12的示例,电机动力轴同步器33c的接合套沿轴向向左运动可以将电机动力轴第一齿轮31与电机动力轴3接合,从而使得电机动力轴3与电机动力轴第一齿轮31能够同步转动。 Example [0070] 12 in conjunction with FIGS. 1, the motor powered shaft 33c of the synchronizer sleeve 31 may be axially leftward movement of the power shaft 3 is engaged with the motor shaft of the first gear in motor power, motor power so that the shaft 3 and motor power shaft of the first gear 31 can be rotated synchronously. 电机动力轴同步器33c的接合套沿轴向向右运动可以将电机动力轴第二齿轮32与电机动力轴3接合,从而使得电机动力轴3与电机动力轴第二齿轮32能够同步转动。 Motor power synchronizer engaging shaft 33c of the sleeve may be axially rightward movement motor power shaft 3 engaged with the second gear 32 along the axis of the motor power, the power shaft 3 so that the motor 32 can be synchronized with the rotation of second shaft gear motor power.

[0071] 当然,可以理解的是,电机动力轴同步器33c的接合套也可以保持在中立位置(例如,初始位置),此时电机动力轴同步器33c与电机动力轴第一齿轮31以及电机动力轴第二齿轮32分别断开。 [0071] Of course, be appreciated that the motor shaft power synchronizer sleeve 33c may be held in a neutral position (e.g., the initial position), the motor case 33c with the power shaft synchronizer motor power shaft of the first gear 31 and a motor The second power shaft gear 32 are disconnected.

[0072] 此外,需要说明一点,为了便于电机动力轴第一齿轮31、电机动力轴第二齿轮32与电机动力轴同步器33c进行接合,电机动力轴第一齿轮31以及电机动力轴第二齿轮32的朝向电机动力轴同步器33c的一侧可以设置有接合齿圈,这对于本领域的普通技术人员而言,应当都是容易理解的。 [0072] Further, it is noted that, in order to facilitate the first motor power shaft gear 31, the motor gear 32 and the power shaft of the second motor power synchronizer shaft 33c for engagement, the first motor power shaft gear 31 and second gear shaft motor power 32 toward the side of the motor shaft power synchronizer 33c may be provided with an engagement ring, which those of ordinary skill in the art, all should be readily understood.

[0073] 由此,电机动力轴3可通过电机动力轴同步器33c的同步(即对电机动力轴第一齿轮31或电机动力轴第二齿轮32的同步)而选择性地与输入轴的一个联动或者与输出轴的一个联动。 A [0073] Thus, the motor shaft 3 via the power shaft synchronous motor power synchronization (i.e., synchronous motor or power shaft 31 of the second gear 32 to the gear shaft of the first motor power) selectively to the input shaft 33c linkage of the output shaft or a linkage. 具体而言,电机动力轴同步器33c可对电机动力轴第一齿轮31进行同步,即电机动力轴同步器33c可接合电机动力轴第一齿轮31与电机动力轴3,从而电机动力轴3能够与输入轴中的一个(例如,第二输入轴12)进行联动。 Specifically, the motor power synchronizer shaft 33c can be synchronized, i.e., motor power synchronizer shaft 33c can engage the first gear shaft 31 and the motor power motor power shaft 3, so that the motor power shaft 3 can be the power the motor shaft of the first gear 31 an input shaft (e.g., the second input shaft 12) linkage. 又如,在一些示例中,电机动力轴同步器33c可对电机动力轴第二齿轮32进行同步,即电机动力轴同步器33c可接合电机动力轴第二齿轮32与电机动力轴3,从而电机动力轴3能够与输出轴中的一个(例如,第二输出轴22)进行联动。 As another example, in some examples, the motor shaft power synchronizer motor 33c may be made to the power shaft of the second synchronous gear 32, i.e., motor power synchronizer shaft 33c can engage the motor gear 32 and the power shaft of the second motor power shaft 3, so that the motor a power shaft 3 can be (e.g., the second output shaft 22) is linked with the output shaft a.

[0074] 下面结合附图对根据本发明实施例的动力传动系统100的倒挡结构进行详细描述。 Reverse drawings The power transmission system structure of an embodiment of the present invention 100 are described in detail [0074] below in conjunction.

[0075] 如上,电机动力轴第一齿轮31与输入轴的一个进行联动。 [0075] As above, a gear shaft of the first motor power linkage 31 and the input shaft. 而在本发明不出的一些实施例中,电机动力轴第一齿轮31是与输入轴的一个上的主动齿轮直接传动或间接传动的,从而实现与该输入轴联动的目的。 In some embodiments of the present invention is not, the power shaft of the first motor is a direct drive gear 31 with the driving gear on the input shaft of a transmission or indirectly, in order to achieve the purpose of interlocking with the input shaft. 例如在图1-图12的示例中,电机动力轴第一齿轮31与对应的主动齿轮例如二挡主动齿轮2a通过一个中间惰轮73间接传动,换言之,中间惰轮73分别与对应的主动齿轮以及电机动力轴第一齿轮31啮合。 For example in the example of FIGS. 12, a first motor power shaft gear 31 with the drive gear, for example, corresponding to second gear, the driving gear 73 indirectly 2a through an intermediate idler gear, in other words, intermediate idler gears 73 respectively corresponding to the driving gear and the first motor power shaft gear 31 meshes.

[0077] 更进一步,中间惰轮73与倒挡中间齿轮72是通过倒挡同步器74c的同步作用而进行联动的,也就是说,倒挡同步器74c设置成用于同步倒挡中间齿轮72和中间惰轮73。 [0077] Still further, intermediate idler gears 73 and reverse idler gear 72 is performed by synchronizing reverse gear synchronizer 74c of the linkage, that is, reverse gear 74c arranged synchronizer for synchronizing the reverse idler gear 72 and an intermediate idler gear 73.

[0078] 关于倒挡同步器74c的设置位置,这里将结合不同的实施例进行描述。 [0078] For the reverse gear position 74c of the synchronizer provided herein in conjunction with various embodiments will be described. 首先,参照图1-图2、图5-图8所示,倒挡中间齿轮72上设置有齿套721,该齿套721可以是空套设置在第二输出轴22上,中间惰轮73空套在该齿套721上。 First, referring to FIGS. 1-2, 5-8, the reverse idler gear 721 is provided on the toothed sleeve 72, the sleeve teeth 721 may be an idler disposed on the second output shaft 22, intermediate idler gears 73 on the idler gear sleeve 721. 倒挡同步器74c设置在齿套721上且用于接合中间惰轮73。 Reverse synchronizer sleeve 74c disposed on the teeth 721 and an intermediate idler gear 73 to engage.

[0079] 其次,在另一些实施例中(未示出),倒挡中间齿轮72上设置有齿套721,该齿套721可以是空套设置在第二输出轴22上,中间惰轮73空套在该齿套721上,倒挡同步器74c设置在中间惰轮73上且用于接合齿套721或用于接合倒挡中间齿轮72。 [0079] Next, other embodiments (not shown), with a reverse idler gear 721 is provided on the sleeve 72, the sleeve teeth 721 may be an idler disposed on the second output shaft 22, intermediate idler gears 73 the idler gear on the sleeve 721, the reverse gear synchronizer 74c provided on the intermediate idler 73 and sleeve 721 for engaging the teeth or for engaging the reverse idler gear 72.

[0080] 再次,如图3-图4、图9-图12所示,在再一些实施例中,倒挡中间齿轮72和中间惰轮73均空套在输出轴的一个上,例如倒挡中间齿轮72和中间惰轮73均空套在第二输出轴22上,并且倒挡中间齿轮72和中间惰轮73彼此相邻,倒挡同步器74c设置在中间惰轮73上且用于接合倒挡中间齿轮72。 [0080] Again, as shown in FIG. 3 to 4, FIG. 9 to 12, in further embodiments, the reverse idler gear 72 and idler gear 73 are intermediate the idler shaft on one output, for example, reverse intermediate idler gear 72 and the intermediate sleeve 73 are empty at the second output shaft 22, and the reverse idler gear 72 adjacent to each other and an intermediate idler gear 73, the reverse gear 74c is provided on the synchronizer intermediate idler gears 73 for engaging and reverse idler gear 72. 当然,可选地,倒挡同步器74c也可以设置在倒挡中间齿轮72上且用于接合中间惰轮73 (未示出)。 Of course, alternatively, reverse gear synchronizer 74c may be provided on the reverse idler gear 72 and idler gear 73 for engaging the intermediate (not shown).

[0081] 对于根据本发明实施例的动力传动系统100,由于采用了上述倒挡结构,因此能够实现机械倒挡模式、电动倒挡模式以及混动倒挡模式。 [0081] For transmission system 100, the use of the above-described reverse configuration, it is possible to achieve mechanical reverse mode according to an embodiment of the present invention, the power, the electric and hybrid reverse mode, reverse mode.

[0082] 机械倒挡模式是利用发动机4的动力实现车辆的倒车功能,在车辆处于机械倒挡模式时,发动机4作为动力源将产生的动力输出至输入轴的一个,即与中间惰轮73联动的输入轴(例如,第二输入轴12),并通过倒挡同步器74c对中间惰轮73与倒挡中间齿轮72的同步而将动力输出至倒挡齿轮71,倒挡齿轮71最终能够将动力输出至车轮,实现倒车。 [0082] The mechanical reverse mode using the power of engine 4 to achieve the reverse function of the vehicle, when the vehicle is mechanical reverse mode, engine 4 as a power source of output power produced to the input shaft, i.e. the intermediate idler 73 interlocking input shaft (e.g., the second input shaft 12), and reverse gear synchronizer 74c via an intermediate idler gear 73 and the reverse idler 72 is synchronized to the power output and the reverse gear 71, the reverse gear 71 eventually the power output to the wheels, to achieve reverse. 简言之,在车辆处于机械倒挡模式时,倒挡同步器74c接合中间惰轮73与倒挡中间齿轮72。 In short, when the vehicle is mechanical reverse mode, reverse gear 74c engaging the synchronizer intermediate idler gears 73 and reverse idler gear 72.

[0083] 电动倒挡模式是利用第一电动发电机51实现车辆的倒车功能,在车辆处于电动倒挡模式,第一电动发电机51作为动力源并通过倒挡同步器74c对中间惰轮73与倒挡中间齿轮72的同步以及电机动力轴同步器33c对电机动力轴第一齿轮31的同步而将动力输出至倒挡齿轮71,倒挡齿轮71最终能够将动力输出至车轮,实现倒车。 [0083] Reverse power mode using the first motor generator 51 implements the reverse functions of the vehicle, an electric vehicle is in reverse mode, the first motor generator 51 as a power source and a reverse gear synchronizer 74c through the intermediate idler 73 and a synchronous motor power shaft 33c of the synchronizer 72 and the output power of the reverse idler shaft of the synchronous motor power of the first gear 31 to the reverse gear 71, the reverse gear 71 to the final output power to the wheels can be realized reversing.

[0084] 即,第一电动发电机51此时作为电动机工作,其产生的动力可依次通过电机动力轴3、电机动力轴同步器33c、电机动力轴第一齿轮31、中间惰轮73、倒挡同步器74c、倒挡中间齿轮72传递至倒挡齿轮71。 [0084] That is, the first motor generator 51 as a motor case, the power which can be generated successively by motor power shaft 3, the motor power synchronizer shaft 33c, the power shaft of the first motor gear 31, intermediate idler gears 73, down synchronizer stopper 74c, the reverse idler gear 72 is transmitted to the reverse gear 71.

[0085] 简言之,在车辆处于电动倒挡模式,倒挡同步器74c接合中间惰轮73与倒挡中间齿轮72,电机动力轴同步器33c接合电机动力轴3和电机动力轴第一齿轮31。 [0085] Briefly, in an electric vehicle is in reverse mode, reverse gear 74c engaging the synchronizer intermediate idler gears 73 and reverse idler gear 72, motor power synchronizer shaft 33c engaging motor power shaft 3 and the first motor power shaft gear 31.

[0086] 混动倒挡模式是同时利用发动机4和第一电动发电机51实现车辆的倒车功能,混动倒挡模式为上述机械倒挡模式与电动倒挡模式的结合。 [0086] hybrid reverse mode simultaneously by the engine 4 and the first motor generator 51 to achieve the reverse function of the vehicle, as a hybrid of the mechanical reverse mode and reverse mode of the motor reverse binding mode.

[0087] 具体而言,在车辆处于混动倒挡模式时,发动机4作为动力源之一将产生的动力输出至输入轴的一个,并通过倒挡同步器74c的同步将动力输出至倒挡齿轮71。 [0087] Specifically, when the hybrid vehicle is in reverse mode, as the power source of the power generated by the engine output to an input shaft 4, and through reverse synchronizer to synchronize the output power of the reverse gear 74c gear 71.

[0088] 与此同时,第一电动发电机51作为另一动力源并通过倒挡同步器74c的同步以及电机动力轴同步器33c对电机动力轴第一齿轮31的同步而将动力输出至倒挡齿轮71。 [0088] Meanwhile, the first motor generator 51 as another power source through the reverse gear 74c of the synchronizer and synchronous motor power synchronizer shaft 33c of the motor shaft of the first gear 31 of the power and the power output to the synchronization inverted speed change gear 71. 艮P,来自发动机4和第一电动发电机51的两部分的动力最终都从倒挡齿轮71输出。 Gen P, the power from the engine 4 and the two parts of the first motor generator 51 is eventually output from the reverse gear 71.

[0089] 该模式下,倒挡同步器74c接合中间惰轮73与倒挡中间齿轮72,电机动力轴同步器33c接合电机动力轴3和电机动力轴第一齿轮31。 [0089] In this mode, the synchronizer reverse idler gear 74c engages the intermediate reverse idler gears 73 and 72, motor power synchronizer shaft 33c engaging motor power shaft 3 and the first motor power shaft gear 31.

[0090]由此,该动力传动系统100能够实现三种倒挡模式,即机械倒挡模式、电动倒挡模式以及混动倒挡模式,丰富了倒挡工况,可以根据实际情况灵活在该三种倒挡模式中进行切换,满足驾驶要求。 [0090] Accordingly, the powertrain system 100 is able to implement three reverse mode, i.e. the mechanical reverse mode, reverse mode, and the electric hybrid reverse mode, reverse enriched conditions, according to the actual situation in the flexible three kinds of switching reverse mode, to meet the requirements of the driver.

[0091] 例如,在车辆电池荷电量充足的情况下,可以采用电动倒挡模式,这样在倒车时不仅不会排放有害气体,而且还能降低能耗,特别对于新的驾驶员倒车入位而言,可能需要操作多次才能将车辆倒入指定位置,而发动机4由于在低速倒车时会产生较多的有害气体,同时发动机4在倒车时一般处于非经济转速区域,油耗相对较高,此时采用电动倒挡模式可以很好地改善这一问题,不仅能够降低排放,同时采用电机作为动力实现低速倒车能耗较低,对发动机4的燃油经济性有一定改善。 [0091] For example, in a vehicle battery fully charged battery condition, motor reverse mode may be employed, so that not only does not emit harmful gases when reversing, but also to reduce energy consumption, especially for the new bits into the reverse driver statement, as many times as may be necessary to specify the position of the vehicle poured, since the engine 4 will produce more harmful gases at low speed reverse, in reverse while the engine 4 is in general non-economic rotational speed region, fuel consumption is relatively high, this when using electric reverse gear mode can greatly improve this problem, not only to reduce emissions, while using the motor as the driving force to achieve lower energy consumption low speed reverse, it could improve the fuel economy of the engine 4.

[0092] 又如,在车辆电池荷电量不充足或较低的情况下,可以采用机械倒挡模式。 [0092] As another example, in the vehicle battery charge or insufficient charge is low, you can use mechanical reverse mode. 再如,在需要快速倒车或者需要大马力倒车等工况下,则可以采用混动倒挡模式,增加车辆的动力性,方便倒车。 Again, the need to reverse or fast reverse and other conditions requires a large horsepower, may be employed in hybrid reverse mode, increase the power of the vehicle, to facilitate parking.

[0093] 当然,上述关于三种倒挡模式应用环境的描述仅是示意性的,不能理解为是对本发明的一种限制或暗示在车辆处于上述环境下必须采用上述对应的倒挡模式。 [0093] Of course, the above description on Three reverse mode application environment is illustrative only and are not to be construed as a limitation of the present invention or a hint must be said corresponding reverse mode the vehicle is in the above circumstances. 对于本领域的普通技术人员而言,显然可以根据需要或实际情况来具体设定相应倒车环境下所需的倒挡模式。 Those of ordinary skill in the art, may be particularly apparent in the respective set the desired environment reverse or reverse mode according to actual needs.

[0094] 另外,需要说明的是,根据本发明实施例的动力传动系统100,其电动倒挡模式以及混动倒挡模式还有另一种实现形式,这将在下面结合具体的实施例详细介绍。 [0094] Further, it is noted that the power transmission system 100 according to an embodiment of the present invention is that the electric and hybrid reverse mode, reverse mode, there is another form of realization, it will be in connection with specific embodiments in detail below introduction.

[0098] 根据本发明实施例的动力传动系统100可以具有五前进挡位,具体地,第一输入轴11上可以布置奇数挡位主动齿轮,第二输入轴12上可以设置布置偶数挡主动齿轮,从而第一输入轴11负责奇数挡位齿轮副的动力传递,第二输入轴12负责偶数挡位齿轮副的动力传递。 [0098] According to the power transmission system embodiment of the present invention may have five forward gear 100, specifically, the first input shaft may be arranged on the odd-numbered gear drive gear 11, the second input shaft 12 may be disposed on the even-numbered speed drive gear arrangement , so that the secondary power input shaft 11 is responsible for the first odd-numbered transmission gear wheel, a second charge of the even sub-input shaft 12 of the power transmission gear wheels.

[0099] 更具体地,如图1-图12所示,第一输入轴11上可以布置有一挡主动齿轮la、三挡主动齿轮3a和五挡主动齿轮5a,第二输入轴12上可以布置有二挡主动齿轮2a和四挡主动齿轮4a,每个挡位主动齿轮均随对应的输入轴同步转动。 [0099] More specifically, as shown in FIG. 1- 12, the first input shaft 11 may have a stopper disposed La drive gear, third-gear drive gear 3a and the fifth speed drive gear 5a, may be arranged on the second input shaft 12 there are two gear 2a and the fourth-gear drive gear drive gear 4a, each gear are rotated synchronously with the drive gear corresponding to the input shaft.

[0100] 对应地,第一输出轴21上设置有一挡从动齿轮lb、二挡从动齿轮2b、三挡从动齿轮3b和四挡从动齿轮4b,第二输出轴22上设置有五挡从动齿轮5b,每个从动齿轮均空套在对应的输出轴上,即每个从动齿轮相对于对应的输出轴能够差速转动。 [0100] Correspondingly, a first output shaft 21 is provided with a driven gear LB, 2B two driven gear, third-gear and fourth-gear driven gear 3b driven gear 4b, five provided on the second output shaft 22 driven gear 5b, each of the idler gears is driven at the corresponding output shaft, i.e. each driven gear being rotatable with respect to the differential output corresponding to the axis.

[0101] 其中,一挡从动齿轮lb与一挡主动齿轮la啮合从而构成一挡齿轮副,二挡从动齿轮2b与二挡主动齿轮2a啮合从而构成二挡齿轮副,三挡从动齿轮3b与三挡主动齿轮3a啮合从而构成三挡齿轮副,四挡从动齿轮4b与四挡主动齿轮4a啮合从而构成四挡齿轮副,五挡从动齿轮5b与五挡主动齿轮5a啮合从而构成五挡齿轮副。 [0101] wherein a driven gear meshed with a gear lb la the pinion gear thereby forming a gear pair, second gear and second-gear driven gear 2b meshing drive gear 2a so as to constitute two gear pairs gear, third-gear driven gear 3b and the third-gear drive gear 3a engaged to constitute the third-gear gear pair, the fourth-gear driven gear 4b and the fourth-gear drive gear 4a meshed gear pair to constitute fourth gear, fifth gear driven gear 5b and the fifth speed drive gear 5a meshed to constitute five-speed gear pair.

[0102] 由于从动齿轮与输出轴之间为空套结构,因此需要设置同步器对相应的从动齿轮与输出轴进行同步,以实现动力的输出。 [0102] Since the structure of the idler, it is necessary synchronizer disposed between the driven gear and the output shaft of the driven gear corresponding to synchronize with the output shaft, in order to achieve power output.

[0103] 在一些实施例中,结合图1-图12所示,动力传动系统100包括一三挡同步器13c、二四挡同步器24c和五挡同步器5c。 [0103] In some embodiments, in conjunction with FIG. 1 to FIG. 12, the power transmission system 100 includes a third gear synchronizer. 13C, two fourth-gear and fifth gear synchronizer 24c synchronizer 5c.

[0104] 如图1所不,一三挡同步器13c设置在第一输出轴21上且位于一挡从动齿轮lb与三挡从动齿轮3b之间,一三挡同步器13c可将一挡从动齿轮lb或三挡从动齿轮3b与第一输入轴11进行接合,从而使该从动齿轮与输出轴能够同步转动。 [0104] FIG. 1 is not, a third gear synchronizer 13c disposed on the first output shaft 21 and located between a driven gear and third-gear driven gear lb 3B, a third gear 13c can be a synchronizer lb driven gear driven gear 3b or three engagement with the first input shaft 11, so that the driven gear and the output shaft can rotate synchronously.

[0105] 例如,结合图1所示,一三挡同步器13c的接合套向左移动可将三挡从动齿轮3b与第一输入轴11接合,从而三挡从动齿轮3b与第一输出轴21能够同步转动。 [0105] For example, in conjunction with FIG. A third gear synchronizer sleeve 13c is moved to the left in FIG. 1 may be three driven gear 11 engaged with the first input shaft 3b, so that three first driven gear with the output 3b shaft 21 can rotate synchronously. 一三挡同步器13c的接合套向右移动可将一挡从动齿轮lb与第一输入轴11接合,从而一挡从动齿轮lb与第一输出轴21能够同步转动。 A third-gear synchronizer sleeve 13c is moved rightward can be a driven gear engaging with the first input shaft 11 lb, lb so that a driven gear and a first output shaft 21 can be rotated synchronously.

[0106] 如图1所示,类似地,二四挡同步器24c设置在第一输出轴21上且位于二挡从动齿轮2b与四挡从动齿轮4b之间,二四挡同步器24c可将二挡从动齿轮2b或四挡从动齿轮4b与第一输入轴11进行接合,从而使该从动齿轮与输出轴能够同步转动。 [0106] As shown, similarly, two fourth gear synchronizer. 1 synchronizer 24c disposed at the first output shaft 21 and located between two driven gear 2b and the fourth-gear driven gear 4b, two fourth-gear 24c It may be two or 2b fourth-gear driven gear 4b of the driven gear engaged with the first input shaft 11, so that the driven gear and the output shaft can rotate synchronously.

[0107] 例如,结合图1所示,二四挡同步器24c的接合套向左移动可将二挡从动齿轮2b与第一输出轴21接合,从而二挡从动齿轮2b与第一输出轴21同步转动。 [0107] For example, in conjunction with FIG. 1, two fourth gear synchronizer sleeve 24c is moved to the left may be bonded two driven gear 2b and the first output shaft 21, so that two first driven gear and output 2b shaft 21 rotate synchronously. 二四挡同步器24c的接合套向右移动可将四挡从动齿轮4b与第一输出轴21结合,从而四挡从动齿轮4b与第一输出轴21同步转动。 Two fourth gear synchronizer sleeve 24c is moved rightward of the fourth-gear driven gear 4b may be joined with the first output shaft 21, thereby 4b rotate synchronously with the first output shaft 21 the fourth-gear driven gear.

[0108] 如图1所示,类似地,五挡同步器5c设置在第二输出轴22上,五挡同步器5c位于五挡从动齿轮5b的一侧,例如左侧,五挡同步器5c用于将五挡从动齿轮5b与第二输出轴22接合,例如五挡同步器5c的接合套向右移动,则可将五挡从动齿轮5b与第二输出轴22接合,从而五挡从动齿轮5b与第二输出轴22同步转动。 [0108] 1, Similarly, the fifth gear synchronizer 5c disposed on the second output shaft 22, fifth gear synchronizer 5c located on a side of the fifth speed driven gear 5b, the left side for example, fifth gear synchronizer 5c for engaging the fifth gear driven gear 5b and the second output shaft 22, for example, fifth gear synchronizer sleeve 5c is moved to the right, you can engage fifth gear driven gear 5b and the second output shaft 22, so that five a second driven gear 5b and the output shaft 22 rotate synchronously.

[0109] 参照图1-图12的实施例,由于倒挡中间齿轮72、中间惰轮73均位于第二输出轴22上,且五挡从动齿轮5b也位于第二输出轴22上,并且五挡同步器5c只用于接合五挡从动齿轮5b、倒挡同步器74c只用于接合中间惰轮73与倒挡中间齿轮72。 [0109] Referring to FIG 1 to FIG 12 of the embodiment, since the reverse idler gear 72, intermediate idler gears 73 are located on the second output shaft 22, and the fifth speed driven gear 5b is also located on the second output shaft 22, and 5c fifth gear synchronizer to engage only five driven gear 5b, only the reverse gear synchronizer 74c for engaging the idler gear 73 and the intermediate reverse idler gear 72. 因此作为一种优选的实施方式,倒挡同步器74c与五挡同步器5c共用一个拨叉机构,由此减少了一套拨叉机构,使得动力传动系统100的结构更加紧凑、尺寸更小。 Accordingly, as a preferred embodiment, the reverse gear 74c and the fifth gear synchronizer synchronizer 5c share a fork mechanism, thereby reducing a fork mechanism, so that the structure of powertrain 100 more compact, smaller in size.

[0110] 可以理解的是,在通过该拨叉机构驱动五挡同步器5c和倒挡同步器74c的接合套动作时,结合图1所示,在该拨叉机构的拨叉驱动五挡同步器5c的接合套向右移动时,五挡同步器5c能够接合五挡从动齿轮5b,此时倒挡同步器74c的接合套不接合倒挡中间齿轮72与中间惰轮73。 [0110] It will be appreciated that, when the driving fifth gear synchronizer 5c and reverse synchronizer sleeve 74c through the operation of the fork mechanism, in conjunction with FIG. 1, the drive fork in the fifth speed synchronous mechanism fork when the sleeve is moved to the right 5c, 5c fifth gear synchronizer to engage fifth gear driven gear 5b, at this time the reverse gear 74c of the synchronizer clutch engagement without the intermediate gear 72 and the reverse idler gear 73 intermediate. 在该拨叉机构的拨叉驱动倒挡同步器74c的接合套接合倒挡中间齿轮72与中间惰轮73时,五挡同步器5c的接合套不接合五挡从动齿轮5b。 Driving the fork in the fork means engaging reverse gear synchronizer sleeve 74c is engaged with the reverse idler gear 72 is intermediate idler gears 73, fifth gear synchronizer sleeve 5c does not engage fifth gear driven gear 5b. 当然,这里关于拨叉机构驱动倒挡同步器74c以及五挡同步器5c的接合套的动作过程仅是示意性的,不能理解为是对本发明的一种限制。 Of course, the drive mechanism on the fork 74c and the reverse gear synchronizer fifth gear synchronizer sleeve 5c of the operation process is illustrative only and are not to be construed as a limitation of the present invention.

[0111] 在本发明的一些实施例中,发动机4与变速器的第一输入轴11和第二输入轴12之间可以是通过双离合器2d进行动力传递或分离的。 [0111], the first input shaft 4 and the engine and the transmission may be carried out in some embodiments of the present invention, the second input shaft 11 through the dual clutch 12 between a power transmission or 2d separation.

[0112] 参照图2-图12所不,双离合器2d具有输入端23d、第一输出端21d和第二输出端22d,发动机4与双离合器2d的输入端23d相连,具体而言,发动机4可以通过飞轮、减震器或扭转盘等多种形式与双离合器2d的输入端23d相连。 [0112] Referring to Figures 2 to 12 do not, a dual clutch having an input terminal 2d 23d, 21d of the first output terminal and a second output terminal 22d, the engine 4 is connected to the input terminal of the dual clutch 2d, 23d, specifically, the engine 4 It may be connected via a flywheel, a shock absorber or the like twisting disc forms the input terminal of the dual clutch 2d 23d.

[0113] 双离合器2d的第一输出端21d与第一输入轴11相连,从而该第一输出端21d与第一输入轴11同步旋转。 A first output terminal [0113] 2d of the dual clutch 21d is connected with the first input shaft 11, such that the first output terminal 21d of the first input shaft 11 rotates in synchronization. 双离合器2d的第二输出端22d与第二输入轴12相连,从而该第二输出端22d与第二输入轴12同步旋转。 Dual clutch 22d of the second output terminal 2d is connected to the second input shaft 12, so that the second output terminal 22d and the second input shaft 12 rotates in synchronization.

[0114] 其中,双离合器2d的输入端23d可以是双离合器2d的壳体,其第一输出端21d和第二输出端22d可以是两个从动盘。 [0114] wherein the dual clutch input terminal 2d, 2d 23d may be double clutch housing, a first output terminal and a second output terminal 21d 22d may be two driven disc. 一般地,壳体与两个从动盘可以是都断开的,即输入端23d与第一输出端21d和第二输出端22d均断开,在需要接合其中一个从动盘时,可以控制壳体与相应从动盘进行接合从而同步旋转,即输入端23d与第一输出端21d和第二输出端22d之一接合,从而输入端23d传来的动力可以通过第一输出端21d和第二输出端22d中的一个输出。 Generally, when the housing and the driven disc may be two are turned off, i.e., a first input terminal and the output terminal 23d of the second output terminal 21d and 22d are turned off, in which a need to engage the driven plate can be controlled housing and the driven plate are joined such that the respective synchronized rotation, i.e., an input terminal 23d 21d engaged with the first output terminal and a second output of one 22d, 23d so that the input terminal of the power may be transmitted from a first and a second output terminal 21d by It outputs a second output terminal 22d.

[0115] 特别地,壳体也可以同时与两个从动盘接合,即输入端23d也可以同时与第一输出端21d和第二输出端22d接合,从而输入端23d传来的动力可同时通过第一输出端21d和第二输出端22d输出。 [0115] In particular, the housing may be engaged simultaneously with the two driven discs, i.e., an input terminal 23d may be simultaneously engaged with the first output terminal and a second output terminal 21d 22d, 23d so that the input terminal of the power can be transmitted simultaneously 22d is output through a first output terminal and a second output terminal 21d.

[0116] 应当理解,双离合器2d的具体接合状态受到控制策略的影响,对于本领域的技术人员而言,可以根据实际所需的传动模式而适应性设定控制策略,从而可以在输入端23d与两个输出端全部断开以及输入端23d与两个输出端至少之一接合的多种模式中进行切换。 [0116] It should be appreciated that the dual clutch engagement state 2d affected specific control strategy, those skilled in the art, the control strategy may be set adaptively according to the actual desired transmission mode, the input terminal 23d thereby 23d switching mode of at least one of the plurality of engagement with the two outputs of the two output terminals and an input terminal are all turned off.

[0117] 关于电机动力轴第二齿轮32,如上,其是与输出轴中的一个进行联动的。 [0117] Regarding the second motor power shaft gear 32, as described above, which is linked with an output shaft. 具体地,在一些实施例中,第二输出轴22上固定设置有传动齿轮6,传动齿轮6与电机动力轴第二齿轮32直接啮合。 In particular, in some embodiments, the second output shaft 22 is fixedly provided 6, drive gear 632 is directly engaged with the motor power transmission gear of the second gear shaft. 前面提到,根据本发明实施例的动力传动系统100还有另外一种电动倒挡模式以及混动倒挡模式,由于电机动力轴第二齿轮32与固定在第二输出轴22上的传动齿轮6啮合,因此来自第一电动发电机51的动力可以通过该条路径输出,实现倒挡功能。 As mentioned earlier, there is another electric drive system 100 reverse mode since the motor and the power shaft gear 32 and a second gear fixed to the output shaft 22 of the second hybrid reverse mode, according to an embodiment of the present invention, the power 6 engaged, thus the power from the first motor generator 51 may be output through the trail, to realize the reverse gear function.

[0118] 具体地,在车辆处于另一种电动倒挡模式,第一电动发电机51作为动力源并通过电机动力轴同步器33c对电机动力轴第二齿轮32的同步而将动力从第二输出轴22输出,动力最终由第二输出轴22输出至车轮,从而实现倒车。 [0118] Specifically, in an electric vehicle is in reverse mode to another, 51 and 32 of the first synchronous generator motor as a power source of the power by a motor shaft 33c of the second synchronizer gear motor power shaft power from the second the output shaft 22, the final output power from the second output shaft 22 to the wheels, thereby realizing the reverse.

[0119] 即,第一电动发电机51此时作为电动机工作,其产生的动力可依次通过电机动力轴3、电机动力轴同步器33c、电机动力轴第二齿轮32、传动齿轮6、第二输出轴22后最终输出给车轮。 [0119] That is, the first motor generator 51 as a motor case, the power which can be generated successively by motor power shaft 3, the motor power synchronizer shaft 33c, the second motor power shaft gear 32, the transmission gear 6, a second the final output shaft 22 outputs to rear wheel.

[0120] 简言之,在车辆处于上述的电动倒挡模式,电机动力轴同步器33c接合电机动力轴3和电机动力轴第二齿轮32,而倒挡同步器74c并不接合中间惰轮73与倒挡中间齿轮72,且倒挡动力也不从倒挡齿轮71处输出。 [0120] Briefly, in an electric vehicle is in said reverse mode, the motor powered shaft 33c engaging motor power synchronizer shaft 3 and the second motor power shaft gear 32, the reverse gear 74c synchronizer 73 does not engage the intermediate idler an intermediate gear 72 and reverse gear, reverse gear and reverse power not from the output gear 71.

[0121] 在车辆处于另一种混动倒挡模式时,发动机4作为动力源之一将产生的动力输出至输入轴的一个,并通过倒挡同步器74c的同步将动力输出至倒挡齿轮71。 [0121] when the vehicle is in another hybrid reverse mode, as the power source of the power generated by the engine 4 is output to an input shaft, and reverse gear synchronizer synchronized by the power output to the reverse gear 74c of the gear 71.

[0122] 与此同时,第一电动发电机51作为动力源并通过电机动力轴同步器33c对电机动力轴第二齿轮32的同步而将动力从第二输出轴22输出,动力最终由第二输出轴22输出至车轮,从而实现倒车。 [0122] Meanwhile, the first motor generator 51 by a motor as a power source and the power shaft 33c synchronizer synchronous motor the power shaft of the second gear 32 and the power output from the second output shaft 22, powered by a second final the output shaft 22 to the wheels, thereby realizing the reverse.

[0123] 当然,由于该模式下倒车动力来自发动机4和第一电动发电机51,因此动力在输出至车轮之前需要进行耦合,例如该两部分动力可以在车辆的主减速器从动齿轮74处进行动力耦合,耦合后的动力最终输出给车轮,从而实现混动倒车。 [0123] Of course, since the power from the engine 4 and reversing the first motor generator 51 in this mode, the power output to the wheel before coupling is required, for example, the two portions may be power driven gear 74 a final drive of the vehicle after the power is coupled to the power, the final output is coupled to the wheel, in order to achieve hybrid reverse.

[0124] 该模式下,倒挡同步器74c接合中间惰轮73与倒挡中间齿轮72,电机动力轴同步器33c接合电机动力轴3和电机动力轴第二齿轮32,倒挡动力一部分从倒挡齿轮71输出、另一部分从第二输出轴22输出。 [0124] In this mode, the synchronizer reverse idler gear 74c engages the intermediate reverse idler gears 73 and 72, motor power synchronizer shaft 33c engaging motor power shaft 3 and the second motor power shaft gear 32, a portion of the reverse power from the inverter speed output gear 71, the other part of the output from the second output shaft 22.

[0125] 对比前一种电动倒挡模式,后一种电动倒挡模式其动力来源不变,即仍然为第一电动发电机51,不同的地方在于,前一种电动倒挡模式中,第一电动发电机51输出的倒挡动力是输出至倒挡齿轮71的,由倒挡齿轮71将动力输出给车轮实现倒挡,而后一种电动倒挡模式中,第一电动发电机51的倒挡动力是从第二输出轴22输出的,由第二输出轴22输出给车轮实现倒挡,即该模式的倒挡动力不经过倒挡齿轮71。 [0125] An electric Comparative former reverse mode, reverse mode after an electric power source which is unchanged, i.e. still the first motor generator 51, difference is that, before an electric reverse mode, the first reverse power an electric generator 51 is outputted to the output gear 71 is the reverse gear, the reverse gear wheel 71 to achieve the power output to the reverse gear, reverse gear and then an electric mode, the first motor generator 51 is inverted notch power is output from the second output shaft 22, the output from the second output shaft 22 to realize the reverse gear wheel, i.e. the power of the reverse pattern 71 without passing through the reverse gear.

[0126] 类似地,对于前一种混动倒挡模式以及后一种混动倒挡模式而言,其均结合了发动机4的倒挡路径以及第一电动发电机51的倒挡路径,区别与上述电动倒挡模式相似,这里不再赘述。 After [0126] Similarly, for the former hybrid reverse mode and one reverse gear in terms of hybrid mode, which both bind the reverse path of the engine and a reverse path 4 the first motor generator 51, the difference and the electric reverse mode similar, will not be repeated here.

[0127] 由此,进一步丰富了动力传动系统100的倒挡模式,给驾驶员更多的选择,充分提高驾驶乐趣,更好地满足不同路况的倒挡要求。 [0127] Thus, further enriching the reverse mode powertrain 100, the driver selects to more fully enhance driving pleasure and better meet the requirements of different road conditions reverse gear.

[0128] 下面结合图2-图12对三个动力输出轴(即第一输出轴21、第二输出轴22和电机动力轴3)与车辆差速器75之间的关系进行详细描述。 [0128] below with reference to FIGS. 2 through the power output shaft 12, three pairs (i.e., a first output shaft 21, second shaft 22 and the motor power output shaft 3) the relationship between the differential 75 and the vehicle described in detail.

[0129] 车辆的差速器75可以布置在一对前轮之间或一对后轮之间,在本发明的一些示例中,差速器75是位于一对前轮之间的。 Differential [0129] The vehicle 75 may be disposed between the pair of front wheels or a pair of rear wheels, in some examples of the present invention, the differential 75 is located between a pair of front wheels. 差速器75的功用是当车辆转弯行驶或在不平路面上行驶时,使左右驱动车轮以不同的角速度滚动,以保证两侧驱动轮与地面间作纯滚动运动。 75 is the differential function of the vehicle when cornering or driving on uneven road surface, the left and right drive wheel rolling at different angular speeds, in order to ensure that both sides of the drive wheel with the ground intercropping pure rolling motion. 差速器75上设置有主减速器从动齿轮74,例如主减速器从动齿轮74可以布置在差速器75的壳体上。 The differential 75 is provided on the main driven gear reducer 74, for example, the main driven gear reducer 74 may be disposed on the housing 75 of the differential. 主减速器从动齿轮74可以是锥齿轮,但不限于此。 Final drive gear 74 may be driven bevel gear, but is not limited thereto.

[0130] 进一步,第一输出轴21上固定设置有第一输出轴输出齿轮211,第一输出轴输出齿轮211随第一输出轴21同步转动,第一输出轴输出齿轮211与主减速器从动齿轮74啮合传动,从而来自第一输出轴21的动力能够从第一输出轴输出齿轮211传递至主减速器从动齿轮74以及差速器75。 [0130] Further, the first output shaft 21 is fixed to the output shaft is provided with a first output gear 211, a first output shaft output gear 21 rotated synchronously with the first 211 output shaft, an output gear 211 with the final drive shaft from the first output gear 74 meshing transmission, so that the power from the first output shaft output gear 21 can be transmitted to the output shaft from the first driven gear 74 and the final drive differential 75,211.

[0131] 类似地,第二输出轴22上固定设置有第二输出轴输出齿轮221,第二输出轴输出齿轮221随第二输出轴22同步转动,第二输出轴输出齿轮221与主减速器从动齿轮74啮合传动,从而来自第二输出轴22的动力能够从第二输出轴输出齿轮221传递至主减速器从动齿轮74以及差速器75。 [0131] Similarly, the second output shaft 22 is fixedly provided on a second output shaft output gear 221, a second output shaft output gear 221 with the second output shaft 22 rotate synchronously, the second output shaft output gear 221 and final drive a driven gear 74 meshing transmission, so that the power from the second output shaft 22 can be output from the second output shaft gear 221 is transmitted to the primary driven gear 74 and a differential gear unit 75.

[0132] 如上,倒挡齿轮71是作为大部分倒挡模式的动力输出端的,因此该倒挡齿轮71同样与主减速器从动齿轮74啮合。 [0132] As above, the reverse gear 71 is the reverse gear mode, as most of the power output, so that the reverse gear 71 meshes with the final drive 74 similarly driven gear. 而由于倒挡齿轮71同时还与倒挡中间齿轮72啮合,同时为了获得适宜的倒挡速比,作为可选的一种实施方式,倒挡齿轮71构造为双联齿轮,该双联齿结构的倒挡齿轮71的一部分与倒挡中间齿轮72啮合,该双联齿结构的倒挡齿轮71的另一部分与主减速器从动齿轮74啮合。 Since the reverse gear 71 and also with the reverse idler 72 meshes, and in order to obtain a suitable reverse speed ratio, as an alternative embodiment, the reverse gear 71 is configured as a double-gear, the double toothing the reverse gear 71 and the reverse idler gear portion 72 meshes, 74 meshes the reverse gear toothing of the double and another portion of the driven gear 71 of the final drive. 换言之,倒挡齿轮71的其中一个齿轮部712是与倒挡中间齿轮72啮合且另一个齿轮部711是与主减速器从动齿轮74啮合。 In other words, in which reverse gear 71 is a gear portion 712 meshed with the reverse idler gear 72 and the other gear 711 is engaged with the main reduction gear 74 driven gear. 由此不仅能够获得良好的倒挡速比,同时倒挡动力传递时各齿轮不会发生干涉,保证倒挡动力传递可靠。 Thus not only can get a good reverse speed, and reverse gears interference does not occur when power transmission, ensure reliable power transmission reverse gear.

[0133] 根据本发明实施例的动力传动系统100的一些典型工况包括驻车发电、双离合器2d同时接合情况下的边驱动边充电以及第一电动发电机51 二挡调速。 [0133] The typical conditions of the present invention, a power transmission system embodiment 100 includes a power generating parking, while the dual clutch 2d side drive second gear 51 while charging speed and the first motor generator in case of engagement.

[0134] 首先描述驻车发电这一典型工况,在车辆处于驻车状态时,发动机4设置成将产生的动力输出至输入轴的一个(即与电机动力轴第一齿轮31进行联动的输入轴,例如第二输入轴12),并通过电机动力轴同步器33c对电机动力轴第一齿轮31的同步而将动力输出至第一电动发电机51,从而驱动第一电动发电机51进行发电。 [0134] First is described the typical profile generation parking when the vehicle is in the parking state, the engine 4 is arranged to generate an output power to one of the input shaft (i.e., a first linkage of the gear motor power input shaft 31 axis, for example, the second input shaft 12), and while the motor outputs power through a power shaft 33c synchronizer synchronous motor the power shaft of the first gear 31 to the first motor generator 51, thereby driving the first motor generator 51 to generate power .

[0135] 具体而言,结合图2-图12示例的具体实施例,发动机4在车辆驻车后能够将动力通过双离合器2d而输出给第二输入轴12,该第二输入轴12与电机动力轴3上的电机动力轴第一齿轮31是联动的,控制电机动力轴同步器33c接合电机动力轴3和电机动力轴第一齿轮31,则发动机4输出的动力将从第二输入轴12、中间惰轮73、电机动力轴第一齿轮31和电机动力轴同步器33c输出至电机动力轴3,最终这部分动力从电机动力轴3输出给第一电动发电机51,从而驱动第一电动发电机51作为发电机进行发电。 [0135] Specifically, 12 in conjunction with specific exemplary embodiments of FIGS. 2, 4 in the engine after parking the vehicle can be powered by the dual clutch 2d and output to the second input shaft 12, the second input shaft 12 and the motor motor power shaft 3, a first gear shaft 31 is a power linkage, the power control of the motor shaft 33c engaging motor power synchronizer shaft 3 and the first motor power shaft gear 31, the power output from the engine 4 from the second input shaft 12 , intermediate idler gears 73, the motor power output shaft of the first gear 31 and the motor power to the motor shaft 33c synchronizer power shaft 3, this final part of the power from the motor power output shaft 3 to the first motor generator 51, thereby driving the first motor generator 51 as a generator for power generation.

[0136] 由此,实现了驻车发电功能,丰富了充电模式,且驻车发电工况下车辆处于静止状态,发动机4的动力可以全部用于充电,提高了充电效率,实现快速供电功能。 [0136] Accordingly, to achieve the parking function generator, the rich charge mode, power generation and the parking condition of the vehicle at a standstill, all the power of the engine 4 may be used for charging, charging efficiency is improved, fast power supply function.

[0137] 其次描述双离合器2d同时接合情况下的边驱动边充电工况,在该工况下,发动机4能够通过输入端23d与第一输出端21d和第二输出端22d的同时接合作用而将其中一部分动力通过其中一根输出轴输出给车轮以作为车辆行驶的动力,并将另一部分动力通过电机动力轴3输出给第一电动发电机51,从而驱动第一电动发电机51进行发电。 [0137] Next described dual clutch 2d side in the case where the driving conditions while engaged while charging, the conditions, the engine 4 is capable of engaging a first output terminal and a second output terminal 21d 22d 23d simultaneously by the action of the input terminal wherein a portion in which the power output to the output shaft of the wheel as the vehicle travels power, and another portion of the power shaft 3 via the power output of the motor to the first motor generator 51, thereby driving the first motor generator 51 generates electric power through.

[0138] 具体而言,结合图2-图12示例的具体实施例,该工况下,发动机4的一部分动力可从第一输出轴21或第二输出轴22输出,例如通过一挡齿轮副、三挡齿轮副或五挡齿轮副输出,发动机4的另一部分动力可从电机动力轴第一齿轮31、电机动力轴同步器33c、电机动力轴3这一路径输出给第一电动发电机51,从而驱动第一电动发电机51发电。 [0138] Specifically, with reference to specific exemplary embodiments of FIG. 2-12, and the conditions, a part of the power of the engine 21 or 4 may be outputted from the first output shaft of the second output shaft 22, a speed gear pair by e.g. three or five sub-gear wheel speed auxiliary output gear, another portion of the power of the engine 4, motor power from the first gear shaft 31, the motor shaft power synchronizer 33c, 3 of the motor power output shaft to the path of the first motor generator 51 , thereby driving the first motor generator 51 to generate electricity.

[0139] 由于传统具有双离合器的动力传动系统中,双离合器2d在同一时刻只有一个离合器处于工作状态,而根据本发明实施例的动力传动系统100实现了对双离合器2d的突破性应用,即在双离合器2d的两个离合器全部接合状态下(输入端23d同时接合第一输出端21 d和第二输出端22d),使得发动机4的一部分动力由一根输出轴输出驱动车辆行驶,另一部分动力则输出给第一电动发电机51,驱动电机发电,丰富了传动模式,兼顾车辆行驶以及充电要求。 [0139] Since the conventional power transmission system having a dual clutch of the dual clutch 2d only one clutch at a time is active, according to an embodiment of the present invention, the power transmission system 100 to achieve a breakthrough for the application of the dual clutch 2d, i.e., in all of the engaging two clutches of the dual clutch 2d state (input terminal 23d while engaging the first output terminal and a second output terminal 21 d 22d), so that a part of the power from the engine 4 with an output drive shaft of the vehicle output, the other part output power to the first motor generator 51, the driving motor generator, the rich-drive mode, with both the vehicle and a charging requirements.

[0140] 再次描述第一电动发电机51的二挡调速功能,具体地,结合图2-图12所示,由于电机动力轴同步器33c布置在电机动力轴第一齿轮31和电机动力轴第二齿轮32之间,第一电动发电机51在作为电动机输出动力时,可以选择性地通过电机动力轴第一齿轮31或电机动力轴第二齿轮32输出,在转换期间,需要电机动力轴同步器33c的同步切换。 [0140] function described again two gear speed of the first motor generator 51, in particular, in conjunction with FIG. 2 to FIG. 12, since the motor shaft power synchronizer shaft 33c is disposed in the first motor power and motor power shaft gear 31 between the second gear 32, the first motor generator 51 as a motor output power, the output may be selectively power the motor or motor shaft of the first gear 31 of the power shaft of the second gear 32, during the transition, the motor requires power shaft 33c synchronous switching of the synchronizer.

[0141] 例如,在从电机动力轴第一齿轮31输出电机动力切换为从电机动力轴第二齿轮32输出动力的过程中,电机动力轴同步器33c的接合套需要从与电机动力轴第一齿轮31接合的位置切换到与电机动力轴第二齿轮32接合的位置,由于电机动力轴第一齿轮31到主减速器从动齿轮74之间传递路径的速比与电机动力轴第二齿轮32与主减速器从动齿轮74之间传动路径的速比是不同的,因此在切换同步器同步电机动力轴第二齿轮32的过程中,电机动力轴第二齿轮32与电机动力轴3是差速转动的,这样会增加同步器的同步时间,同时也增加了同步器的磨损,降低传动效率,容易出现动力中断或长时间无法同步而引起的顿挫感。 [0141] For example, the first switching gear 31 from the motor power output shaft of the motor power during the second gear 32 of the motor output power of the power shaft, the motor shaft power synchronizer sleeve 33c of the power required from the first motor shaft gear 31 engaged position to the engaged position with a second gear motor power shaft 32, since the first gear ratio and the motor shaft motor power transmitting path between the power shaft 7431 of the second driven gear to the final drive gear 32 the ratio between the transmission path 74 of the final drive of the driven gear are different, so the process of switching the synchronous motor power shaft of the second synchronizing gear 32, the motor power shaft gear 32 and a second motor power shaft 3 is the difference speed rotation, which increases the synchronization time synchronizer, but also increases wear synchronizer, reducing transmission efficiency, power interruption or prolonged sense of frustration caused by not synchronize prone.

[0142] 此时,可以控制第一电动发电机51基于电机动力轴第二齿轮32的转速而调节电机动力轴3的转速,即以电机动力轴第二齿轮32的转速为目标来提升或降低电机动力轴3的转速,使得电机动力轴3的转速能够在最短的时间内与电机动力轴第二齿轮32匹配(即大致相等或接近),从而使得电机动力轴同步器33c能够快速接合电机动力轴第二齿轮32与电机动力轴3,减少电机动力轴同步器33c同步所需的时间,极大地提高了车辆的传动效率、同步可控性和同步的实时性。 [0142] In this case, the first motor generator 51 may be controlled based on the rotational speed of the motor of the power shaft of the second gear 32 and the motor to adjust the speed of the power shaft 3, i.e., the rotation speed of the second gear 32 to the motor shaft as a target power to raise or lower power shaft rotation speed of the motor 3, so that the power shaft rotation speed of the motor 3 is a motor capable of matching the power shaft of the second gear 32 (i.e., substantially equal to or close to) in the shortest possible time, so that the motor power synchronizer shaft 33c engaging motor power can be quickly the second gear 32 and the motor shaft power shaft 3, the motor powered shaft to reduce the time required to synchronize the synchronizer 33c, greatly improve the transmission efficiency of the vehicle, real-time synchronization and controllability synchronization. 此外,电机动力轴同步器33c的寿命得以进一步延长,从而降低整车维护的成本。 In addition, the motor power shaft 33c synchronizer life is further extended, thus reducing vehicle maintenance costs.

[0143] 类似地,在从电机动力轴第二齿轮32输出电机动力切换为从电机动力轴第一齿轮31输出动力的过程中,第一电动发电机51可以基于电机动力轴第一齿轮31的转速调节电机动力轴3的转速,即以电机动力轴第一齿轮31转速为目标提升或降低电机动力轴3的转速,使得电机动力轴3的转速能够在最短的时间内与电机动力轴第一齿轮31匹配,从而提高电机动力轴同步器33c的接合效率。 [0143] Similarly, the second gear 32 in the power output of the motor is switched from motor power shaft gear 31 during a first output power, the first motor generator 51 may be based on the motor shaft of the first gear 31 of the power from the motor shaft power adjusting the rotational speed of the power shaft rotation speed of the motor 3, i.e., the rotational speed of the motor 31 to the power shaft of the first gear to raise or lower the target power shaft rotation speed of the motor 3, so that the power shaft rotation speed of the motor 3 can be the power shaft of the first motor in the shortest time matching gear 31, thereby improving the power efficiency of the motor engaging the shaft 33c of the synchronizer.

[0144] 综上,简言之,电机动力轴同步器33c在与电机动力轴第一齿轮31和电机动力轴第二齿轮32中的一个接合切换为与另一个接合期间,第一电动发电机51设置成以电机动力轴第一齿轮31和电机动力轴第二齿轮32中的另一个的转速为目标对电机动力轴3进行调速。 [0144] In summary, in short, motor power synchronizer shaft 33c with the motor shaft of the first gear 31 and the power during the motor power shaft engaging a second gear switch 32 is engaged with the other, the first motor generator 51 further arranged to power the motor 32 in the second gear speed of the motor shaft of the power shaft of the first gear 31 and the target speed for the motor power shaft 3.

[0145] 针对第一电动发电机51调速这一功能,典型工况是在纯电动模式下,即第一电动发电机51驱动车辆行驶时。 [0145] 51 for the first motor generator speed this feature, typical working conditions are in electric mode, i.e. the first motor generator 51 is driven when the vehicle is traveling. 当然,本发明并不限于此,对于其它模式例如混动模式,需要电机动力轴同步器33c来切换电机动力轴第一齿轮31和电机动力轴第二齿轮32时,均可以米用第一电动发电机51对电机动力轴3进行调速。 Of course, the present invention is not limited thereto, for other modes such hybrid mode, motor power synchronizer shaft 33c to the first switching gear 31 and the motor shaft motor power of the second power shaft gear 32, a first electric meters can be 51 pairs of the generator motor power shaft 3 for speed.

[0146] 由此,根据本发明实施例的动力传动系统100,电机动力轴同步器33c在电机动力轴第一齿轮31和电机动力轴第二齿轮32之间切换接合位置时,通过第一电动发电机51对电机动力轴3的调速,使得电机动力轴3的转速能够与待接合的齿轮(例如电机动力轴第一齿轮31或电机动力轴第二齿轮32)转速相匹配,即第一电动发电机51能够以待接合的齿轮的转速为目标对电机动力轴3的转速进行调节,使电机动力轴3的转速与待接合的齿轮的转速在短时间内匹配,方便电机动力轴同步器33c的接合,从而大大提高了传动效率,减少中间能量的传递损失。 [0146] Accordingly, when the embodiment according to the power transmission system 100 according to the present invention, the motor powered shaft 33c synchronizer 31 and the motor power of the motor in the power shaft of the first gear shaft 32 between the second switching gear engaged position, the first motor 51 pairs of the power generator speed motor shaft 3, so that the motor power shaft gear (e.g., motor power or motor shaft of the first gear 31 of the power shaft of the second gear 32) of the rotational speed of 3 to be engageable with the speed match, i.e., a first the rotational speed of the motor generator 51 can power the motor shaft 3 is adjusted to the rotational speed of the gear to be engaged as a target, the motor speed of the power shaft 3 matches the rotational speed of the gear to be engaged in a short time, the motor powered shaft to facilitate synchronizer 33c is engaged, thus greatly improving the transmission efficiency, to reduce the transmission loss of the intermediate energy.

[0147] 根据本发明的一些实施例的动力传动系统100,还可以增设第二电动发电机52以增加动力传动系统100的动力性,丰富传动模式。 [0147] Transmission 100 may also be an additional second power motor generator 52 in accordance with some embodiments of the present invention to increase Powertrain 100, a rich-drive mode.

[0148] 例如,在其中一些实施例中,第二电动发电机52可与主减速器从动齿轮74传动,例如第二电动发电机52的电机轴上可以设置齿轮,该齿轮与主减速器从动齿轮74直接啮合传动。 [0148] For example, in some of these embodiments, the second motor-generator 52 can be driven with the main drive gear reducer 74, for example, the motor shaft of second motor generator 52 may be a gear, the main gear reducer the driven gear 74 directly meshing transmission. 又如,在另一些实施例中,第二电动发电机52也可以设置成与第一输入轴11相连或与第一输出轴21相连。 As another example, in other embodiments, the second motor generator 52 may be arranged in connection with the first input shaft 11 or the shaft 21 is connected to the first output. 再如,在再一些实施例中,第二电动发电机52为两个且分别设置在差速器75的两侧,例如该两个第二电动发电机52可以与差速器75集成为一体。 Again, in still other embodiments, the second motor generator 52 is two and the differential 75 are provided on both sides of, for example, the two second motor generator 52 may be integrated with the differential 75 as a whole . 或者,前述的发动机4和第一电动发电机51用于驱动前轮,第二电动发电机52也可以是轮边电机并用于后轮,或者第二电动发电机52可以通过一个减速机构驱动两个后轮,或者第二电动发电机52为两个且分别通过一个减速机构驱动一个后轮。 Alternatively, the engine 4 and the first motor generator 51 for driving the front wheels, the second motor generator 52 may be used for the rear wheel and the motor, the second motor generator 52 or the two may be driven through a speed reduction mechanism rear wheels, or the second motor generator 52 is two and one rear wheel are driven through a reduction mechanism.

[0149] 下面参考图5-图12详细描述根据本发明实施例的电子差速锁结构,该结构能够实现在出现车轮打滑现象时锁止打滑的一对驱动轮,从而改善打滑现象,提高车辆通过性倉泛。 [0149] Next, with reference to Figures 5 to 12 in detail the structure of an electronic differential lock according to embodiments of the present invention will be described, the structure can be implemented in the event of wheel slip lockup slip phenomenon pair of drive wheels, thereby improving slipping and improve vehicle by positions of the pan.

[0150] 如图5-图12所示,该电子差速锁结构包括第三电动发电机201、第四电动发电机301和防滑同步器503。 [0150] As shown in FIG. 5 through 12, the electronic differential lock structure includes a third motor generator 201, motor generator 301 and a fourth synchronizer 503 skid. 其中,发动机4和/或第一电动发电机51用于驱动第一对车轮76,第三电动发电机201和第四电动发电机301设置成用于驱动第二对车轮77,其中第一对车轮76为前轮和后轮中的一对,第二对车轮77为前轮和后轮中的另外一对。 Wherein the engine 4 and / or the first motor generator 51 for driving a first pair of wheels 76, the third and fourth motor generator 201 is provided to the motor generator 301 for driving the second pair of wheels 77, wherein the first pair front and rear wheels of the wheel 76 of the pair, the second pair of wheels 77 for the front and rear wheels of the another pair. 在图5-图12的示例中,发动机4和第一电动发电机51驱动前轮,第三电动发电机201和第四电动发电机301分别用于驱动两个后轮。 In the example of FIG. 5 to FIG. 12, the engine 4 and the first motor generator 51 drive the front wheels, the third and fourth motor generator 201 for driving motor generator 301, respectively, the two rear wheels.

[0151] 结合图5-图12所示,第三电动发电机201设置成与第二对车轮77中的一个联动,换言之,第三电动发电机201可将动力输出给该一个车轮以驱动该一个车轮转动,或者第三电动发电机201也可以从该一个车轮吸收能量,从而进行发电。 [0151] As shown in conjunction with FIGS. 5, a third motor generator 201 is arranged in conjunction with a second pair of wheels 77, in other words, the third motor generator 201 may be a power output to the driving wheel 12 of the a wheel rotation, the third motor or generator 201 may absorb the energy from a wheel for generating electricity.

[0152] 类似地,第四电动发电机301设置成与第二对车轮77中的另一个联动,换言之,第四电动发电机301可将动力输出给该另一个车轮以驱动该另一个车轮转动,或者第四电动发电机301也可以从该另一个车轮吸收能量,从而进行发电。 [0152] Similarly, the fourth motor generator 301 is arranged in conjunction with the other second pair of wheels 77, in other words, the fourth power of the motor generator 301 can be output to the other wheels to drive the rotation of the other wheel , or the fourth motor generator 301 may absorb energy from the other wheel, thereby performing the power generation. 在图5-图12的示例中,第三电动发电机201与左后轮联动,第四电动发电机301与右后轮联动,但本发明并不限于此。 In the example of FIG. 5 to FIG. 12, the third motor generator linked with the left rear wheel 201, fourth motor generator 301 in conjunction with the right rear wheel, but the present invention is not limited thereto.

[0153] 防滑同步器503设置成可选择性地同步第二对车轮77,从而使得第二对车轮77同步旋转,换言之,在防滑同步器503同步第二对车轮77 (即防滑同步器503处于接合状态),第二对车轮77之间形成固联形式,从而同步旋转,不会差速转动。 [0153] The synchronizer 503 is arranged to slip selectively synchronizing the second pair of wheels 77, so that the second pair of wheels 77 rotate in synchronization, in other words, the synchronizer 503 in synchronization slip the second pair of wheels 77 (i.e., the synchronizer 503 is slip engaged state) is formed between a second pair of wheels 77 is fixedly connected form, to synchronize rotation of the differential rotation is not.

[0154] 而在防滑同步器503处于断开状态时,第三电动发电机201和第四电动发电机301可以分别驱动对应的车轮以不同的转速转动,实现两个车轮的差速转动功能,当然,在防滑同步器503处于断开状态时,第三电动发电机201和第四电动发电机301也可以驱动该第二对车轮77以相同的转速转动。 [0154] In the non-slip synchronizer 503 is in the OFF state, the third and fourth motor generator 201 to drive the motor generator 301 corresponding to each of the wheels at different rotational speeds to achieve the differential rotation of the two wheels of the function, of course, the synchronizer 503 when the skid is in the off state, the third and fourth motor generator 201 may be a motor generator 301 drives the second pair of wheels 77 rotate at the same rotational speed.

[0155] 由此,通过设置第三电动发电机201和第四电动发电机301分别单独驱动第二对车轮77,从而能够实现第二对车轮77的差速转动,而在出现其中一个车轮打滑现象时,防滑同步器503可以同步第二对车轮77以使第二对车轮77同步旋转,实现两个电机(当然也可以是一个)输出的动力耦合后共同驱动第二对车轮77运转工作,改善车轮打滑现象,提高车辆的通过能力。 [0155] Accordingly, motor generator 201 by providing the third and fourth motor generator 301 separately drives the second pair of wheels 77, so that the second pair of wheels 77 of the differential rotation can be realized, in which a wheel slip occurs when the phenomenon, the synchronization slip 503 may synchronize the second pair of wheels 77 so that the second pair of wheels 77 rotate in synchronization, to achieve two motors (of course, may be a) a second pair of wheels 77 drive a common driving operation after power is coupled out, improve wheel slippage and improve the capability of the vehicle.

[0291] 下面在再一个具体实施例中对根据能量回馈需求扭矩选择第一电动发电机的挡位的具体工作过程进行说明。 [0291] In the following a further particular embodiment of the torque feedback based on the energy demand for the process of selection of a particular work gear of the first motor generator will be described. 如图17所示,具体可以包括: As shown in FIG 17, specifically comprising:

[0292] S201,根据相应的输入信号(如制动踏板深度、起始车速、路面状况等),获取滑行回馈扭矩曲线或制动踏板深度-制动回馈扭矩曲线,并根据滑行回馈扭矩曲线获得混合动力汽车滑行能量回馈控制时的最小目标值,或根据制动踏板深度-制动回馈扭矩曲线获得混合动力汽车的当前制动回馈目标值。 [0292] S201, in accordance with a corresponding input signal (e.g., the depth of a brake pedal, the initial vehicle speed, road conditions, etc.), obtaining feedback coasting torque profile depth or the brake pedal - a brake feedback torque curve and the torque curve is obtained according to feedback coasting hybrid vehicle when the minimum target coasting energy feedback control, or the depth of a brake pedal - a brake torque curves obtained reserved hybrid vehicle brake feedback current target value.

[0295] S204,根据比较结果确定能量回馈需求扭矩Tmax。 [0295] S204, feedback energy demand torque Tmax is determined based on the comparison.

[0296] 需要说明的是,混合动力汽车在进行能量回馈时,以一定的起始车速开始,根据整车制定的回馈策略,在每个当前车速和制动踏板的深度下对应有一个回馈扭矩值T,这个回馈扭矩值τ就是整车在回馈时第一电动发电机需提供的能量回馈需求扭矩Tmax。 [0296] Incidentally, the hybrid vehicle during energy feedback, a certain initial speed starts, the vehicle in accordance with the policy established by feedback, a feedback torque corresponding to the current vehicle speed and the depth of each of the brake pedal value T, the torque feedback value τ is the energy at the time of vehicle feedback required the first motor generator demand torque feedback Tmax.

[0297] S205,根据第一电动发电机的第一挡位速比以及当前车速等信息,确定第一挡位当前提供的最大回馈扭矩Ta。 [0297] S205, a first gear ratio in accordance with a first motor generator and the current vehicle speed and other information, to determine the maximum torque feedback current provided by the first gear Ta.

[0298] S206,根据第一电动发电机的第二挡位速比以及当前车速等信息,确定第二挡位当前提供的最大回馈扭矩Tb。 [0298] S206, a second gear ratio according to the first motor generator and the current vehicle speed and other information, to determine the maximum torque Tb feedback current provided by the second gear.

[0299] 具体地,当第一档位为EV1挡,第二挡位为直接挡时,由变速箱的制造工艺可知,第一挡位速比大于第二挡位速比,从如图1-12所示的动力传动系统的结构中可以看出,第一档位的传递层级为6级,第二挡位的传递层级为4级,每级的传动效率大概可认为是 [0299] Specifically, when the gear position is first gear EV1, the second gear is a direct gear, is apparent from the manufacturing process of the gearbox, a first gear ratio than the second gear ratio, from FIG. 1 structure illustrated -12 powertrain can be seen, the first transmission gear level is 6, the second transmission gear level is level 4, the transmission efficiency of each stage can be considered probably

0.97,则η级的传动效率为0.97的η次方。 0.97, then the level of transmission efficiency η is η 0.97 power. 因此,第一档位的传动效率小于第二挡位的传动效率。 Thus, the transmission efficiency of the first gear is less than the transmission efficiency of the second gear. 根据第一电动发电机端的功率Ρ1传到轮端(即变速箱输出轴端)时的功率Ρ2 =Ρ1/&,其中,&为传动效率,以及第一电动发电机的自身特性可知,当第一电动发电机工作于恒功率状态时,车速一定,传动效率&越小,则传到轮端的功率Ρ2越大,因此第一档位的扭矩大于第二挡位的扭矩,从而Ta > Tb。 Ρ2 = Ρ1 when power according to the power transmitted to the wheel side rho] 1 (i.e., transmission output shaft) of the first motor generator end / &, wherein the transmission efficiency of & understood, and its own characteristics of the first motor generator, when the first a motor generator operates in a state of constant power, constant speed, greater transmission efficiency & smaller, the power transmitted to the wheel side [rho] 2, and thus the first gear of the second gear torque is greater than the torque so Ta> Tb. 另外,当第一电动发电机工作于恒扭矩状态时,由于轮端的扭矩为电机端扭矩乘以速比,因此,速比越大,传递到轮端的扭矩越大,从而Ta>Tb。 Further, when the first motor generator operating in the constant torque state, since the torque of the wheel side end of the motor torque ratio is multiplied, therefore, the greater the ratio, the greater is transmitted to the wheel end torque, thereby Ta> Tb. 综合来看,第一挡位当前提供的最大回馈扭矩Ta大于第二挡位当前提供的最大回馈扭矩Tb。 Taken together, the first gear torque Ta of the current maximum feedback provided by feedback torque Tb greater than the maximum current provided by the second gear.

[0300] S207,比较能量回馈需求扭矩Tmax、第一挡位当前提供的最大回馈扭矩Ta、第二挡位当前提供的最大回馈扭矩Tb的大小。 [0300] S207, feedback comparing the energy demand torque Tmax, the first gear to provide maximum feedback current torque Ta, a second gear to provide maximum feedback current magnitude of the torque of Tb.

[0301] S208,根据比较结果确定挡位的选择情况。 [0301] S208, where the gear selected is determined based on the comparison result.

[0302] S209,如果Tmax > Ta,控制第一电动发电机选择第一挡位。 [0302] S209, if Tmax> Ta, the first motor generator control of a first selected gear.

[0303] S210,如果Tb < Tmax < Ta,控制第一电动发电机选择第二挡位。 [0303] S210, if Tb <Tmax <Ta, the first motor generator control of a second selected gear.

[0304] S211,如果Tmax < Tb,控制第一电动发电机选择第二挡位。 [0304] S211, if Tmax <Tb, controlling the first motor generator selects the second gear.

[0305] S212,根据选择的相应挡位,整车进行能量回馈控制。 [0305] S212, feedback control according to the corresponding energy of the selected gear, vehicle.

[0306] 本发明实施例的混合动力汽车的能量回馈控制方法能够通过对各输入信息进行充分地、准确地分析和考虑后在双挡(第一挡位和第二挡位)中选择不同的挡位进行能量回馈,从而直接提高整车回馈时的稳定性以及能量的可回收效率,其中,采用双挡进行能量回馈的优势具体表现在以下三个方面: [0306] Examples of the energy of the hybrid vehicle of the embodiment of the present invention can be sufficiently and accurately analyzed and considered by the respective input information feedback control method selected in the double gear (first gear and second gear) different gear energy back, thus directly improve the stability and efficiency of energy recovered during the vehicle's back, wherein the dual advantage of retaining specific energy feedback in the following three aspects:

[0307] (1)、由于第一挡位(例如EV1挡)比第二挡位(例如直接挡)所能达到的最低车速更小,而第二档位(例如直接挡)比第一挡位(例如EV1挡)所能达到的最高车速更大,因此,当采用双挡进行能量回馈时,覆盖的能够进行能量回馈的车速范围比单独采用第二挡位更广。 [0307] (1), since the first minimum speed gear (e.g., gear EV1) than the second gear (e.g., a direct gear) can be achieved less, and a second gear position (e.g. direct gear) than the first gear bits (e.g., EV1 speed) can achieve a greater maximum speed, and therefore, when the double speed feedback energy, capable of covering the energy range than the vehicle speed feedback alone wider second gear.

[0308] (2)、由于整车在进行能量回馈时,低转速段的回馈扭矩不易进行控制,容易出现波动。 [0308] (2), due to the vehicle during the energy return, low speed torque feedback section is not easy to control, tends to be volatile. 而采用双挡进行能量回馈时,由于第一档位(例如EV1挡)速比比第二挡位(例如直接挡)速比大,因此可以将能量回馈时的车速降低,并且相对提高低车速时第一电动发电机端的转速,使得更加容易控制回馈扭矩,并且整车的操纵感更好,没有较强的顿挫感。 While dual energy back stop, the first gear position (e.g., EV1 speed) is larger than the second gear ratio (e.g. direct gear) ratio, the vehicle speed can be reduced when the energy back, and a relatively low vehicle speed increase end of the first motor generator speed, making it easier to control the torque feedback, and better vehicle steering feeling, without a strong sense of frustration.

[0309] (3)、如果仅以第二档位(例如直接挡)进行能量回馈,根据HEV模式的定义(在HEV模式下,第一电动发电机以双挡进行驱动)及如图1-12所示的动力传动系统的结构可知,当不再发电并且需要进行驱动时,需切换到第一挡位(例如EV1挡)进行驱动,这样会造成挡位间的频繁切换,动力性能有所滞后。 [0309] (3), if only the second gear (e.g., a direct gear) for energy feedback (in the HEV mode, the first motor generator is driven at double speed) and the HEV mode according to the definition of FIG. 1- structure powertrain shown in Figure 12 shows that, when no drive power is required and, to be switched to the first gear (e.g., gear EV1) is driven, this will cause frequent switching between gears, power performance has lag. 而采用双挡进行能量回馈,则不会出现这种挡位间的来回频繁切换,从而有效的改善了整车的动力性。 The use of dual energy back stop, the gear back and forth between such frequent switching does not occur, thus effectively improving the power performance of the vehicle.

[0328] 本发明实施例的混合动力汽车的动力传动系统100能够通过对各输入信息进行充分地、准确地分析和考虑后在双挡(第一挡位和第二挡位)中选择不同的挡位进行能量回馈,从而直接提高整车回馈时的稳定性以及能量的可回收效率,其中,采用双挡进行能量回馈的优势具体表现在以下三个方面: [0328] Power hybrid vehicle according to an embodiment of the present invention, the drive system 100 can be sufficiently accurately by analyzing the input information and the respective selected in consideration of the double gear (first gear and second gear) different gear energy back, thus directly improve the stability and efficiency of energy recovered during the vehicle's back, wherein the dual advantage of retaining specific energy feedback in the following three aspects:

[0329] (1)、由于第一挡位(例如EV1挡)比第二挡位(例如直接挡)所能达到的最低车速更小,而第二档位(例如直接挡)比第一挡位(例如EV1挡)所能达到的最高车速更大,因此,当采用双挡进行能量回馈时,覆盖的能够进行能量回馈的车速范围比单独采用第二挡位更广。 [0329] (1), since the first minimum speed gear (e.g., gear EV1) than the second gear (e.g., a direct gear) can be achieved less, and a second gear position (e.g. direct gear) than the first gear bits (e.g., EV1 speed) can achieve a greater maximum speed, and therefore, when the double speed feedback energy, capable of covering the energy range than the vehicle speed feedback alone wider second gear.

[0330] (2)、由于整车在进行能量回馈时,低转速段的回馈扭矩不易进行控制,容易出现波动。 [0330] (2), due to the vehicle during the energy return, low speed torque feedback section is not easy to control, tends to be volatile. 而采用双挡进行能量回馈时,由于第一档位(例如EV1挡)速比比第二挡位(例如直接挡)速比大,因此可以将能量回馈时的车速降低,并且相对提高低车速时第一电动发电机端的转速,使得更加容易控制回馈扭矩,并且整车的操纵感更好,没有较强的顿挫感。 While dual energy back stop, the first gear position (e.g., EV1 speed) is larger than the second gear ratio (e.g. direct gear) ratio, the vehicle speed can be reduced when the energy back, and a relatively low vehicle speed increase end of the first motor generator speed, making it easier to control the torque feedback, and better vehicle steering feeling, without a strong sense of frustration.

[0331] (3)、如果仅以第二档位(例如直接挡)进行能量回馈,根据HEV模式的定义(在HEV模式下,第一电动发电机以双挡进行驱动)及如图1-12所示的动力传动系统的结构可知,当不再发电并且需要进行驱动时,需切换到第一挡位(例如EV1挡)进行驱动,这样会造成挡位间的频繁切换,动力性能有所滞后。 [0331] (3), if only the second gear (e.g., a direct gear) for energy feedback (in the HEV mode, the first motor generator is driven at double speed) and the HEV mode according to the definition of FIG. 1- structure powertrain shown in Figure 12 shows that, when no drive power is required and, to be switched to the first gear (e.g., gear EV1) is driven, this will cause frequent switching between gears, power performance has lag. 而采用双挡进行能量回馈,则不会出现这种挡位间的来回频繁切换,从而有效的改善了整车的动力性。 The use of dual energy back stop, the gear back and forth between such frequent switching does not occur, thus effectively improving the power performance of the vehicle.
