Description

用于同步和驱动变速器齿轮箱中间轴的***的模块
技术领域
本发明涉及车辆变速器领域，更具体地，涉及用于同步和驱动变速器齿轮箱中间轴的***的模块，以及用于控制这种同步和驱动***的方法。
背景技术
众所周知，车辆变速器齿轮箱包括由车辆内燃机驱动的主轴、驱动车辆从动轮的副轴以及能够通过对应于不同传动比的齿轮组联接到输出轴和输入轴的中间轴。
文献WO04013517教导了使用联接到变速器齿轮箱的中间轴的齿轮箱制动器，以在传动比变化的过渡阶段期间减慢中间轴，以帮助变速器齿轮箱同步，从而减少传动比变化的过渡阶段的长度。
文献GB1435517和AT520019公开了一种可逆电机，其永久地联接到变速器齿轮箱的中间轴。因此，在传动比变化的过渡阶段，可逆电机能够以发电机模式运行以降低中间轴的速度，或者以电动机模式运行以增加中间轴的速度，从而有助于同步变速器齿轮箱。在这些文献中，可逆电机总是连接到中间轴，因此产生增加主发动机燃料消耗的阻力矩。此外，在可逆电机发生故障的情况下，或者当电池已经达到其最大充电，使得使用可逆电机来使中间轴减速会带来损坏该电池的风险时，则在传动比变化的过渡阶段不再可能制动变速器齿轮箱的中间轴，并且这在安全性方面造成了明显的问题。
发明内容
本发明背后的一个想法是提出一种用于驱动和同步中间轴的***的模块，该模块能够通过允许使用可逆电机来同步变速器齿轮箱而克服现有技术的缺点，而不增加主发动机的消耗或危及车辆的安全性。
为此，根据一实施例，本发明涉及一种用于驱动和同步变速器齿轮箱的中间轴的***的模块，所述模块包括：
-旨在安装在车辆底盘上但不能旋转的支承部件；
-能够相对于支承部件旋转的联接装置，该联接装置包括用于可旋转地联接到可逆电机的输入元件和用于可旋转地联接到中间轴的输出元件，该联接装置具有联接状态和分离状态，在联接状态下，离合器装置能够在输入元件和输出元件之间传递扭矩，在分离状态下，输入元件和输出元件分离；以及
-锁定装置，其具有锁定状态和释放状态，在锁定状态下，所述锁定装置阻止离合器装置的输入元件相对于支承部件旋转，在释放状态下，所述锁定装置允许输入元件相对于支承部件旋转。
因此，由于联接装置，可逆电机可以在传动比变化的过渡阶段之外与中间轴分离，从而使得可以减少主发动机的消耗。
此外，通过将锁定***置于锁定状态，联接装置能够像齿轮箱制动器一样起作用，而不对可逆电机提出要求，特别是在可逆电机发生故障的情况下或者当给可逆电机供电的电池已经达到其最大充电时。
根据其他有利实施例，这种模块可以具有一个或多个以下特征。
根据一实施例，输入元件由支承部件支撑和旋转引导。
根据一实施例，锁定装置包括能够在锁定位置和释放位置之间移动的移动元件，在锁定位置，所述移动元件与输入元件接触以阻止其旋转，在释放位置，所述移动元件远离输入元件以允许其旋转。因此，锁定直接在输入元件上执行，从而避免了锁定力的施加点和离合器装置的输入元件之间的角度间隙，并因此使得可以当其用作齿轮箱制动器时优化联接装置的性能，以限制不期望的噪音并增加驱动和同步***的可靠性。
根据一实施例，输入元件包括输入毂，其在支承部件内被支撑和旋转引导，并且在锁定位置，移动元件与输入毂接触。
根据一实施例，锁定装置包括在输入毂的外周上制成的多个孔，并且移动元件是销，该销安装成能够在支承部件中形成的洞中滑动，并且当销处于锁定位置时，该销具有***其中一个孔中的端部。
根据一实施例，孔具有倒角入口，以便于销在锁定位置***孔中。根据一替代实施例，或者另外，销具有倒角端部，以便于销在锁定位置***孔中。
根据一实施例，锁定装置包括返回构件，该返回构件配置成将移动元件返回到释放位置，并且连接到气动或液压操作回路，该气动或液压操作回路配置成将移动元件朝向锁定位置移动。这使得可以限制锁定装置的能量消耗，因为锁定装置将花费更多的时间处于释放状态，并且仅在极少的情况下处于锁定状态。
根据另一实施例，锁定装置可以包括在输入毂的外周上制成的多个齿，并且移动元件是绕平行于并远离中间轴的旋转轴线X的轴线Y铰接的杠杆，并且当杠杆处于锁定位置时，该杠杆具有***两个齿之间的端部。
根据一实施例，该模块还包括减速齿轮组，该减速齿轮组联接到联接装置的输入元件，并且用于将联接装置的输入元件旋转地联接到可逆电机，并且在锁定状态下，锁定装置与减速齿轮组的齿轮配合，以便阻止其旋转。
根据一实施例，联接装置是多片湿式离合器装置。因为这种联接装置具有改进的冷却能力和相当无噪音的操作，所以它特别适合用作发动机制动器。
根据一实施例，本发明还涉及一种用于驱动和同步变速器齿轮箱的中间轴的***，该***包括前述模块和可逆电机，该可逆电机包括联接到联接装置的输入元件的转子。
根据一实施例，可逆电机的转子通过减速齿轮组联接到联接装置的输入元件。
根据一实施例，本发明还涉及一种包括变速器齿轮箱的变速器组件，该变速器齿轮箱包括旨在连接到主发动机的主轴、旨在连接到车辆的从动轮的副轴以及能够通过齿轮组联接到输出轴和输入轴的中间轴，该变速器组件还包括前述驱动和同步***，联接装置的输出元件可旋转地联接到中间轴。
根据一实施例，本发明还涉及一种车辆，其包括前述变速器组件、通过离合器装置连接到主轴的主发动机和连接到副轴的从动轮。
最后，根据一实施例，本发明涉及一种控制用于驱动和同步变速器齿轮箱的中间轴的***的方法，包括响应于临界事件的检测将锁定装置从释放状态移动到锁定状态的步骤。
根据一实施例，临界事件指示可逆电机的故障、为可逆电机供电的电池的充电状态高于最大充电阈值、温度低于电池的最小使用温度或温度高于电池的最大使用温度。
根据一实施例，当锁定装置处于锁定状态时，响应于改变传动比的指令，根据代表中间轴的设定点转速的信号控制联接装置，使得联接装置施加允许中间轴获得中间轴的设定点转速的阻力矩。
附图说明
参考附图，从本发明的多个特定实施例的以下描述中，将更好地理解本发明，并且本发明的其他目的、细节、特征和优点将变得更加清楚，这些描述仅通过非限制性说明的方式提供。
图1示出了装备有用于驱动和同步变速器齿轮箱的中间轴的***的车辆的传动系。
图2是图1中驱动和同步***的离合器装置和锁定装置的局部透视图和剖面图。
图3是图2的离合器装置和锁定装置的剖视图。
图4是图2的离合器装置和锁定装置在不同截面上的另一剖视图。
图5是本发明第二实施例的正面视图。
具体实施方式
图1示出了车辆的传动系1，其包括主发动机2(例如内燃机)、变速器齿轮箱3和用于驱动和同步变速器齿轮箱3的中间轴5的***4。
主发动机2通过任何合适类型的离合器装置8(例如滑动离合器)连接到变速器齿轮箱3的主轴6。离合器装置8具有接合状态和分离状态，在接合状态下，离合器装置8能够在主发动机2和变速器齿轮箱3的主轴6之间传递扭矩，在分离状态下，主发动机2和变速器齿轮箱3的主轴6分离。
变速器齿轮箱3容纳在变速器壳体7内。变速器齿轮箱3包括主轴6、中间轴5和副轴9，副轴9旨在通过未示出的差速器连接到车辆的从动轮。
变速器齿轮箱3包括与中间轴5一体旋转的中间轴齿轮10、11、12、13、14。
变速器齿轮箱3还包括两个主齿轮15、16，它们与主轴6同轴且各自与中间轴齿轮10、11中的一个形成齿轮组。三位置双同步器17允许主齿轮15、16中的一个或另一个联接到主轴6，并且具有主齿轮15、16都不联接到主轴6的空档位置。
变速器齿轮箱3还包括与副轴9同轴的副齿轮18、19、20。副齿轮18、19、20分别与中间轴齿轮12、13、14中的一个形成齿轮组。由副齿轮18、19、20和相应的中间轴齿轮12、13、14形成的齿轮组永久啮合。其中一个齿轮组在其中一个副齿轮20和其中一个中间轴齿轮14之间具有附加齿轮21，以便产生能够使副轴9的旋转方向反向的倒档传动比。定位在两个副齿轮19、20之间的没有同步器的三位置牙嵌式联轴器22使得可以将两个相关的副齿轮19、20中的一个或另一个联接到副轴9，或者在空档位置保持副齿轮19、20与副轴9分离。
在所示的实施例中，主轴6的旋转轴线与副轴9的旋转轴线对齐。此外，主齿轮16定位成使得它跨在主轴6的一端和副轴9的一端上。因此，所述主齿轮16也可以通过旋转地联接到副轴9而用作副齿轮。为此，定位在所述主齿轮16和副齿轮18之间的三位置牙嵌式联轴器23使得可以将主齿轮16或副齿轮18联接到副轴9，并且还使得可以在空档位置保持主齿轮16和副齿轮18与副轴9分离。这样的变速器齿轮箱3因此具有六个前进档和两个倒档，如果适用的话，它们可以在副轴9的输出处联接到行星齿轮组(未示出)，以便获得12速变速器齿轮箱。
驱动和同步***4与变速器齿轮箱3的中间轴5相关，以便驱动或制动其。驱动和同步***4包括由电池43供电的可逆电机24、减速齿轮组25和联接装置26。
可逆电机24包括定子和转子，转子通过减速齿轮组25连接到联接装置26。联接装置26具有联接状态和分离状态，在联接状态下，其能够在可逆电机24和中间轴5之间传递扭矩，在分离状态下，可逆电机24和中间轴5之间的扭矩传递被中断。
驱动和同步***4尤其旨在用于变速器齿轮箱3的传动比变化的过渡阶段。具体地，在这些过渡阶段期间，可逆电机24可以用作电动机以增加中间轴5的转速，或者用作电动制动器以降低中间轴5的转速。因此，中间轴5的转速的这种适应使得可以减少传动比变化的过渡阶段的长度。
在瞬态阶段之外，可逆电机24也可以用于电动机模式，其中可逆电机24向车轮提供驱动扭矩。可逆电机24能够与主发动机2联合使用，以为车辆的牵引提供附加动力。在这种情况下，离合器装置8处于接合配置。根据一实施例，可逆电机24也可以在车辆牵引是纯电动的模式下使用。在这种操作模式下，离合器装置8处于分离配置。此外，可逆电机24也可以在电流发生器模式下用于给电池43充电。
在过渡阶段之外，并且当可逆电机24既不在发电机模式下使用也不在电动机模式下使用时，联接装置26处于分离状态，以便限制可逆电机24可能产生的阻力矩，从而使得可以减少主发动机2的燃料消耗。
结合图2至图4的第一实施例，可以看到根据第一实施例的模块48，其包括安装在车辆底盘上不能旋转的支承部件33，以及驱动和同步***4的联接装置26。
联接装置26包括联接到可逆电机24的输入元件27和联接到中间轴5的输出元件28(仅在图1中示意性示出，在图2至4中未示出)。在联接状态下，联接装置26能够在输入元件27和输出元件28之间传递扭矩。相反，在分离状态下，输入元件27和输出元件28之间的扭矩传递被中断。
输入元件27包括输入毂29。输入毂29包括内部花键30，并用于接收轴(未示出)的花键端，该轴通过减速齿轮组25联接到可逆电机24。输入毂29在支承部件33内被支撑和旋转引导，该支承部件33固定到变速器系1的壳体(该壳体未示出)，并且该支承部件33旨在固定到车辆的底盘。根据本发明的另一变型，支承部件33可以是滑动轴承。根据本发明的另一变型，滚针或滚珠轴承可以径向***支承部件33和输入毂29之间。
在所示的实施例中，联接装置26是多片湿式联接装置。输入元件27包括两个固定在一起的半壳体31、32，它们一起限定容纳多片组件的内部空间，当所述联接装置26处于联接状态时，多片组件用于在输入元件27和输出元件28之间传递扭矩，还包括致动活塞34和诸如油的液压流体。
多片组件包括多个例如由钢制成的环形板35，这些环形板与输入元件27一体旋转，并且安装成能够相对于输入元件27轴向滑动。为此，每个板35在其外周上具有外齿组，该外齿组与形成在输入元件27的半壳体31、32之一的圆柱形裙部的内部上的内齿组啮合。多片组件还包括多个***板35之间的摩擦盘36。摩擦盘36与输出元件28一体旋转，具有轴向平移运动的自由度。为此，输出元件28包括外齿组，并且每个摩擦盘36在其内周上包括与输出元件28的外齿组啮合的内齿组。每个摩擦盘36包括布置在其前后面上的摩擦衬片。
此外，致动活塞34安装成能够在输入元件27的内部空间内轴向移动。致动活塞34在其外周上包括密封件37，其与半壳体31的圆柱形裙部密封地配合，以便在致动活塞34和半壳体31的端壁39之间限定可变容积密封室38。此外，半壳体31的端壁39具有在图3中可见的导管40，该导管40通过形成在支承部件33中的导管41连接到装配有泵(未示出)的液压回路。
当可变容积密封室38被供应加压流体以将联接装置26朝向联接状态移动时，致动活塞34朝向多片组件移动，使得摩擦盘36被挤压在板35之间，并且扭矩因此在输入元件27和输出元件28之间传递。
相反，当液压流体从可变容积密封室38中排出时，致动活塞34滑离多片组件，使得摩擦盘36和板35返回到分离位置，其中它们轴向彼此隔开。
此外，模块48还包括锁定装置42，特别是在图2和4中可见，该锁定装置具有锁定状态和释放状态，在锁定状态下其阻止输入元件27相对于支承部件33旋转，在释放状态下其允许输入元件27相对于所述支承部件33旋转。因此，当锁定装置42处于锁定状态时，联接装置26可以在变速器3的传动比变化的过渡阶段期间制动中间轴5。联接装置26则充当齿轮箱制动器，而不对可逆电机24提出要求。这种锁定状态尤其用在可逆电机24发生故障的情况下，或者当与可逆电机24相关的电池43已经达到其最大充电时，使得使用可逆电机24来制动中间轴5会带来损坏电池43的风险。
模块48的构成不限于结合图2至4描述的第一实施例的构成。例如，模块48也可以包括减速齿轮组25的全部或一部分，锁定装置42可以位于扭矩在可逆电机24的转子和联接装置26的输入元件27之间传递的路径上的任何位置。
因此，锁定装置42可以显著地与减速齿轮组25的一个齿轮相关，轴在减速齿轮组25和离合器的输入元件27之间传递扭矩，或者直接与离合器装置的输入元件27相关，如所示实施例中的情况。该最后布置是特别有利的，因为它避免了由锁定装置42施加的旋转阻挡力的施加点和离合器装置的输入元件27之间的角间隙，这种角间隙在联接装置26用作齿轮箱制动器时易于降低其性能，从而产生不舒适的噪音并导致驱动和同步***4恶化。
在所示的实施例中，锁定装置42包括多个孔44，在图2中可见，这些孔均匀地分布在离合器装置的输入毂29的外周上，以及能够***所述孔44之一中的移动销45。销45安装成能够在形成于支承部件33中的洞46中在一方面锁定位置和另一方面释放位置之间滑动，在锁定位置，销45的端部***其中一个孔44中，从而阻止输入元件27的旋转，在释放位置，销45的端部脱离孔44，允许输入元件27旋转。
在所示的实施例中，为了使销45在锁定位置更容易***孔44中，孔44具有倒角入口，销45具有倒角端部，倒角入口和倒角端部构造成便于销45***孔44中。
锁定装置42还包括返回构件47，例如螺旋弹簧，其位于洞46的肩部和销45的肩部之间，从而允许销45朝向释放位置返回。此外，支承部件33的板46与液压或气动回路(未示出)连通，该回路配备有泵，该泵允许压力施加到销45上，以便将销45移动到锁定位置并保持在锁定位置。
注意，锁定装置42在上文中以示例的方式进行了描述，并且本发明不以任何方式限于表现出这种结构的锁定装置42。因此，根据实施例变型，销45在锁定位置和释放位置之间的运动由电致动器引起。此外，根据另一实施例，锁定装置42是爪形离合器联接装置。这种爪形离合器联接装置包括例如滑动套筒，其包括一组齿并且在旋转方面是固定的。滑动套筒能够在一方面锁定位置和另一方面释放位置之间轴向移动，在锁定位置，滑动套筒的齿组与互补齿组啮合，该互补齿组与输入毂29一体旋转以阻止后者的旋转，在释放位置，齿组彼此分开以允许输入毂29旋转。
图5描述了本发明的第二实施例，其中锁定装置42包括围绕离合器装置的输入毂29的外周均匀分布的多个齿54和能够***两个齿54之间的杠杆55。杠杆55绕平行于并远离中间轴5的旋转轴线X的轴线Y铰接在一方面锁定位置和另一方面释放位置之间，在锁定位置，杠杆55的端部***两个齿54之间并因此阻止输入元件27的旋转，在释放位置，杠杆55的端部脱离齿44，允许输入元件27旋转。
在所示的该第二实施例中，当杠杆处于锁定位置时，杠杆55具有***两个齿54之间的端部56。为了便于杠杆55在锁定位置***两个齿54之间，齿54具有倒角入口，并且杠杆55在其端部具有倒角。
锁定装置42还包括返回构件47，例如扭簧，该返回构件47位于形成在锁定装置42上的端部止动件58和杠杆55中的孔之间，从而允许杠杆55朝向释放位置返回。此外，杆55通过推杆59移动，推杆59能够在杠杆55上施加压力，以便将杠杆55移动到锁定位置并保持在锁定位置。
下文描述了在传动比变化的过渡阶段操作如上所述的驱动和同步***4的方法。
在传动比变化的过渡阶段期间，驱动和同步***4提供两种可选择的操作模式，在下文中分别称为标准模式和降级模式。当没有检测到指示可逆电机24或为其供电的电池43的运行状态的临界事件时，驱动和同步***4以标准模式运行。相反，当检测到这种临界事件时，它以降级模式运行。临界事件例如对应于检测到可逆电机24的故障，或者对应于检测到与可逆电机24相关的电池43的充电状态高于最大阈值充电。
临界事件还可以对应于检测到低于电池最低使用温度的温度或者高于电池最高使用温度的温度。
在标准模式下，锁定装置42处于其释放状态，联接装置26操作成使得如果它已经处于联接位置则它保持在该位置，或者从分离位置移动到联接位置。可逆电机24根据代表中间轴5的设定点转速的信号来控制。
响应于检测到临界事件，驱动和同步***4切换到降级模式。锁定装置42然后从其释放状态移动到其锁定状态。然后，根据代表中间轴5的设定点转速的信号来控制联接装置26，使得联接装置26施加允许中间轴5获得中间轴5的设定点转速的阻力矩。因此，联接装置26充当齿轮箱制动器。
尽管已经结合多个特定实施例描述了本发明，但显然本发明决不局限于此，并且本发明包括所描述的装置的所有技术等同物及其组合，这些都落入由权利要求限定的本发明的范围内。
在权利要求中，括号之间的任何参考符号都不能被解释为限制权利要求。
