Abstract

本发明涉及一种具有电动转矩矢量分配系统(eTV)的混合动力式后桥传动机构(H‑HAG)、一种用于机动车、尤其是插电式混合动力车辆(PHEV)的动力传动系和一种电动转矩矢量分配(电动Torque Vectoring)方法。

Description

混合动力式后桥传动机构
技术领域
本发明涉及一种具有电动转矩矢量分配系统(eTV)的混合动力式后桥传动机构(H-HAG)、一种用于机动车、尤其是插电式混合动力车辆(PHEV)的动力传动系和一种电动转矩矢量分配方法。
背景技术
具有转矩矢量分配(TV)的传统后桥传动机构(HAG)包括布置在左侧和右侧的传统车桥传动机构以及叠加单元。叠加单元包括叠加传动机构和膜片离合器。借助集成的膜片离合器，叠加传动机构可以在系统边界内可变地在后桥的车轮之间分配驱动功率。膜片离合器由液压控制单元操纵。电机驱动油泵，该油泵提供必要的液压压力。由单独的控制器控制和监控所有功能。叠加传动机构包括两个同轴布置的、具有一个减速级(i1>1)和一个加速级(i2<1)的空心轮变速器。借助于叠加传动机构可以根据膜片离合器的力锁合的情况随着转速提高而接入附加的力矩。因此，所传输的功率增加。可传输的转矩差与可通过膜片离合器传递的最大转矩有关。因此，摩擦片组最大直径的结构空间也对最大转矩差形成限制。与高车辆重量(例如在PHEV的情况下)相结合，带有TV的HAG通过具有膜片离合器的叠加单元提供的转矩差不足以实现运动式车辆所要求的足够动态化的行驶性能。这是因为，具有膜片离合器的叠加单元所仅能提供的车轮转速提高不能实现对行驶动力学性能(预期在弯道入口处)的稳定干预。
带有差速锁止机构的混合动力式双挡后桥传动机构(H-HAG)具有传统的锥齿轮差速器，该锥齿轮差速器通过万向轴连接在中央差速器上。另外，电机(在P4布置中)可以经由双挡变速器作用在差速器的冠齿轮上。锥齿轮差速器被实施为具有液压操作的膜片离合器的差速器锁止器。与提高行驶动力学性能的附加式中央差速器/挂接式中央差速器(Hang-On-Mitteldifferential)(不是H-HAG的组成部分)相结合，差速锁止机构可以稳定地干预。因此，在弯道出口处的行驶动力学性能可能在动态感受到的、过度控制的行驶行为的方向上受到影响。P4-电机通过双挡变速器与传动系的连接的实施方案除了在主变速器中的切换之外还要求在后桥上的切换。这引起P4-电机的驱动力矩的牵引力中断。通过在后桥上的这种附加的切换，同时对车辆的舒适性和动力性产生不利影响。在后桥上的差速锁止机构在全轮驱动的车辆中在转弯出口处的行驶动力学性能的范围中总是承担稳定的作用。此外，为了使车辆采取运动型的行驶行为，必须使用附加式中央差速器。只有通过在附加式中央差速器中的驱动力矩的可变分配才能实现对行驶动力学性能的迅速干预。
WO 2015/169 837A1公开了一种用于车辆的转矩矢量分配装置，所述转矩矢量分配装置包括经由变速器连接到差速机构的电机，其中，转矩矢量分配装置还包括至少一个控制装置，以用于在第一模式和第二模式之间改变变速器的转矩路径，在所述第一模式中，变速器将电机与用于混合动力式驱动模式的差速机构输入轴连接，在所述第二模式中，变速器将电机与用于转矩矢量分配模式的差速机构输出轴连接。
DE 10 2019 129 670 A1涉及一种具有转矩矢量分配的混合动力式车桥驱动装置。电动车桥驱动使用电机通过末端驱动传动装置和差速器驱动两个半轴。转矩矢量分配传动装置通过响应于制动器的接合将功率从半轴中的一个传递到电机或从电机传递到半轴来改变转矩分配。使用阶梯式行星齿轮组实现末端驱动传动装置和转矩矢量分配传动装置。末端驱动传动装置和差速器位于电机的一端。转矩矢量分配传动装置位于电机的相对端。
DE 10 2009 059 903 A1公开了一种用于在机动车的至少一个车桥内可变地分配力矩的系统，该系统包括主驱动装置和力矩矢量分配马达。
发明内容
在这种背景下，本发明的目的在于，提供一种用于插电式混合动力车辆(PHEV)的后桥传动机构和动力传动系，利用所述后桥传动机构和动力传动系能够实现具有高行驶动力学性能的行驶性能，尤其是即使在转弯行驶时也能够实现具有高行驶动力学性能的行驶性能。
根据本发明，该目的通过具有权利要求1和权利要求7的特征的产品和具有权利要求10的特征的方法来实现。本发明的扩展方案和改进方案由从属权利要求、说明书和附图中得出。
根据本发明，为了进一步提高PHEV动力传动系的性能，使用具有电动转矩矢量分配系统(eTV)的混合动力式后桥传动机构(H-HAG)。作为借助于万向轴的传统机械驱动的补充，使用永久连接的集成的电机，所述电机具有用于提高推进力以及用于再生的变速器。另外，使用带有集成的电力电子装置的单独的电机，该单独的电机驱动电动转矩矢量分配系统(eTV)。eTV系统不仅用于提高横向动力学性能，而且用于提高行驶稳定性。利用H-HAG，通过动力传动系的模块化扩展来实现整个系统功率的提高。H-HAG是模块化构造的并且是可变型的(动力电机和eTV系统可以被单独地集成)。
本发明的主题涉及一种用于机动车、尤其是PHEV的后桥传动机构，所述后桥传动机构包括小齿轮轴、具有锥齿轮齿部和圆柱齿轮齿部的空心轴以及差速器，该差速器具有固定地连接到差速器壳体上的圆柱齿轮，其中，小齿轮轴与机动车的万向轴连接，小齿轮轴的小齿轮啮合到空心轴的锥齿轮齿部中，空心轴的圆柱齿轮齿部啮合到差速器的圆柱齿轮的齿部中。
小齿轮轴与车辆的万向轴连接，该万向轴传递由车辆的内燃机和/或电机提供的驱动力矩。空心轴横向于小齿轮轴的轴线和车辆的纵轴线布置。空心轴的圆柱齿轮齿部将驱动力矩传递到差速器。空心轴形成后桥传动机构的副轴并且能够实现差速器的非居中布置。通过使用副轴，提供了用于集成动力电机的更大的结构空间，并且能够取消锥齿轮齿部的准双曲面偏置。由于缺少锥齿轮传动的剪切作用，取消准双曲面偏置使功率损失降低，并且实现了对于整个后桥传动机构(H-HAG)仅使用唯一的润滑油种类。
在后桥传动机构的一种实施方式中，差速器与动力电机的变速器相连接。
在后桥传动机构的一种实施方式中，连接轴穿过具有圆柱齿轮的空心轴，所述圆柱齿轮是变速机构的组成部分。在另一种实施方式中，变速机构连接到叠加单元，该叠加单元连接到差速器的输出轴。在另一实施方式中，叠加单元包括双列行星齿轮机构，该双列行星齿轮机构具有用于两个行星齿轮组的、自由运行的/能转动的、一体式的齿圈。在另一种实施方式中，双列行星齿轮机构包括与差速器壳体连接的第一行星架和第一行星齿轮、与变速器连接的第一太阳轮、与输出轴连接的第二行星架和第二行星齿轮、以及相对外壳固定的第二太阳轮。
在一个实施例中，后桥传动机构包括润滑系统，该润滑系统基于齿轮将润滑油输送到储油器并且随后由于重力驱动将油分配到润滑点。
本发明的主题还涉及一种用于插电式混合动力车辆(PHEV)的动力传动系，所述动力传动系包括内燃机和至少一个动力电机以及根据本发明的后桥传动机构。
在动力传动系的一个实施例中，动力电机通过变速器连接到差速器。在一个实施例中，动力电机是永久连接的、具有固定传动比(1挡)的动力电机。动力电机的永久连接的优点包括：使转矩增强模式和再生模式中的死时间最小化、消除由于换挡过程引起的牵引力中断、以及通过取消换挡机械而节省重量。
在动力传动系的一个实施方式中，包括电机和电力电子装置的驱动模块(eTV驱动模块)经由连接轴、变速器和叠加单元连接到后桥传动机构的差速器。因此，该eTV系统包括eTV驱动模块(电机和集成的电力电子装置)和机械叠加单元。
在一个实施方式中，动力电机和eTV驱动模块通过主动的水冷却系统被冷却。
本发明的主题还涉及一种用于在机动车的、尤其是PHEV的后桥的两个输出轴之间进行转矩分配(电动的转矩矢量分配，eTV)的方法。在该方法中，驱动模块(eTV驱动模块)通过变速器(eTV变速器)和叠加单元(eTV叠加单元)引起输出轴的加速或减速，该叠加单元具有双列行星齿轮机构，该双列行星齿轮机构包括与差速器壳体连接的第一行星架和第一行星齿轮、与变速器连接的第一太阳轮、与输出轴中的一个输出轴连接的第二行星架和第二行星齿轮、以及相对外壳固定的第二太阳轮，所述输出轴与叠加单元的第二行星架连接。驱动模块包括电机和电力电子装置。
电动转矩矢量分配系统的优点在于，能在紧凑的结构空间中实现高力矩差、能实现相对于液压系统较高的调节品质、实现后轮加速和减速(总是反向)的干预可能性、并由此实现对车辆的行驶动力学性能进行迅速、稳定干预的可能性。
本发明的其它优点和设计方案由说明书和附图得出。
不言而喻，前面所述的和后面还要阐述的特征不仅可以以相应说明的组合应用、而且可以以其他组合应用或者被单独应用，这都不脱离本发明的范围。
