自动和手动变速器常常用于汽车上。这些变速器变得越来越复杂,因为必须调整发动机速度来限制车辆的消耗和排放。在常用变速器中对发动机速度的更精细控制能通常仅通过添加齿轮和增加总复杂性和成本来实现。因此,6速手动变速器变得像8或9速自动传动装置那样常见。

具体实施方式
常用于汽车上的自动和手动传动装置是无级变速器或CVT。这种CVT包括许多类型,诸如带有可变滑轮的皮带、超环面和圆锥形。CVT的原理在于其允许发动机通过根据车辆速度无级地改变传动比而以其最高效的旋转速度运行。若需要,例如,当加速时,CVT也能转换到提供更多动力的比例。CVT能将该比例从最小比例改变到最大比例,而不会有任何动力传输中断,这与通过脱开以转换比例而需要中断动力传输的常用传动装置相反。CVT的具体用途是无限式无级变速器或IVT。在CVT限于正速比的情况下,IVT配置能无级地执行空挡和甚至倒车。在某些传动系配置中,CVT可以用作IVT。
本文描述了基于球型CVT,也被称作CVP(恒定变速行星传动装置)的传动系配置,其所采用是福布鲁克技术公司(Fallbrook Technologies,Inc.)以参考US20040616399P和AU2011224083A1的专利。这种CVT包括:一定数量的球(取决于具体应用);作为输入和输出,具有与球接触的圆锥形表面的两个圆盘;以及惰轮,如图1所示。这种CVT包括一定数量的球(取决于具体应用);作为输入995和输出996,具有与球接触的圆锥形表面的两个圆盘;以及惰轮999,如图1所示。球997安装于轴998上,它们本身保持在笼或行星架中,从而允许通过使球的轴倾斜而改变传动比。也存在其它类型的球CVT,包括米尔纳无级变速器(MCVT)(MCVT)。
在图2中示出了工作原理。CVP自身利用牵引流体工作。在球与圆锥形齿圈之间的润滑剂在高压下充当固体,将动力从输入圈通过球转移到输出圈。通过使球的轴线倾斜,在输入与输出之间的比例可以改变。当轴线水平时,该比例是一,当轴线倾斜时,在轴线与接触点之间的距离变化,修改总比例。所有球的轴线同时随着包括于笼中的机构倾斜。
在汽车中,CVT用于替换传统传动装置并且位于发动机100与差速器102之间,如图3所示。在某些情形下,扭转阻尼器101引入于发动机100与CVT 103之间,以避免转移可能严重损坏CVT的扭矩峰值和振动。在某些配置中,这个阻尼器可以与离合器联接用于起动功能。
在某些情形下,连续式无级变速器(CVT)是不太理想的。动力比例可能并非最有效和高效的,动力传输可能频繁地中断,并且变速器可能涉及使用庞大笨重的零件。因此,需要克服了这些问题中至少某些问题的改进的连续式无级变速器(CVT)。
提供用于以更平稳和更高效的方式传递动力的系统、装置和方法。在某些实施例中,这以更少或更小的零件实现。在某些实施例中,本文所公开的动力传输装置具有一种或多种操作模式,例如连续式无级变速传动(CVT)模式、无限式无级变速传动(IVT)模式和IVT/CVT模式,通过接合不同的离合器或制动器来选择这些模式。在某些实施例中,该设备允许利用最少数量的离合器和制动器在连续式无级变速传动(CVT)模式与无限式无级变速传动(IVT)模式之间进行模式转变。

在汽车20中,CVT 203用于替换传统传动装置并且位于发动机200与差速器202之间。在某些情形下,扭转阻尼器201引入于发动机200与行星齿轮系211和212之间,如图4所示。配置1c/(图4)使用双太阳轮行星系211和212,然后连接到变速机构213。在双太阳轮行星系中,第一平面的行星齿轮系211的行星轮和第二平面的行星齿轮系212的行星轮由单件制成。在某些实施例中,将变速机构的输出连接到额外的行星齿轮系217。在某些实施例中,通过采用离合器216将其太阳轮和行星架锁定在一起,这个行星齿轮系被锁定为以1:1比例转动。在某些实施例中,通过采用超速离合器216锁定行星齿轮系的太阳轮到地面来具有更多范围从而实现速度增加。在某些实施例中,这个行星齿轮系的齿圈然后连接到末级驱动222和差速器202。在某些实施例中,变速机构的第二齿圈连接到第三行星齿轮系的行星架。在某些实施例中,这种配置包括两个制动器,一个用于IVT模式214和一个用于CVT模式215。在某些实施例中,该配置的中央部分包括上文所描述的变速机构。在某些实施例中,在变速机构的每一侧上的球斜道提供传递扭矩所需的夹持力。
在某些实施例中,双太阳轮行星齿轮系的行星架218连接到变速机构的输入齿圈219。在某些实施例中,通过采用IVT离合器214,在IVT模式下,双太阳轮行星齿轮系的行星架218连接到外壳。在某些实施例中,第二行星齿轮系220的太阳轮连接到变速机构221的行星架。在某些实施例中,通过采用CVT离合器215,在CVT模式下,第二行星齿轮系220的太阳轮连接到外壳。在某些实施例中,总比例通常为双太阳轮行星齿轮系传动比、变速机构传动比、输出行星齿轮系217传动比和末级驱动器传动比222的乘积。在某些实施例中,通过变速机构的IVT模式实现了停车、很低车辆速度和倒车。
在某些实施例中,通过释放一个制动器并且闭合另一个制动器来简单地进行两种模式(CVT与IVT)之间的转变。而且,输出行星齿轮系的离合器216可以用于选择在输出行星齿轮系217中的比例1:1或者超速传动比。在这两种额外比例之间的转变简单地通过改变离合器216所接合的零件来进行。在某些实施例中,这个装置能连续地改变其比例,以根据消耗量或动力目标提供该发动机可实现的最佳比例。在某些情形下,在手动或自动传动装置中,仅可以提供某些预定和离散的比例,并且需要中断动力传输来转换比例。在某些情形下,在这个装置中唯一的动力中断是为了改变模式。其它优点包括(但不限于):小末级驱动器(以一个步骤,无需副轴)和系统的成本效益。在某些实施例中,通过添加第三行星齿轮系,范围高于传统齿轮箱,这改进了车辆的总体效率。在某些实施例中,设备允许利用最少数量的制动器在连续式无级变速传动(CVT)模式与无限式无级变速传动模式(IVT)之间进行模式转换。

在某些实施例中,三太阳轮行星齿轮系的行星架(318)连接到变速机构输入齿圈(319)。在某些实施例中,通过采用制动器(318),在IVT模式下,行星架(318)连接到外壳。在某些实施例中,第三行星齿轮系(313)的太阳轮连接到变速机构(321)的行星架。在某些实施例中,通过采用制动器(316),在CVT模式下,第三行星齿轮系(313)的太阳轮连接到外壳。在某些实施例中,在IVT/CVT模式下,通过采用制动器(317),第二行星齿轮系的太阳轮连接到外壳,因此,允许变速机构输入齿圈(319)和变速机构行星架(321)都被驱动。在某些实施例中,关于速度,这种IVT/CVT模式位于IVT模式与CVT模式之间。在某些实施例中,总比例是三太阳轮行星齿轮系传动比、变速机构传动比和末级驱动比的乘积。在某些实施例中,利用变速机构的IVT模式通常实现停车、很低车辆速度和倒车。
在某些实施例中,通过接合一个制动器和释放其它制动器来简单地进行三种模式之间的转变。在某些实施例中,这个装置能连续地改变其比例,以根据消耗量或动力目标提供该发动机可实现的最佳比例。在某些情形下,在手动或自动传动装置中,仅可以提供某些预定和离散比例并且需要中断动力传输来转换比例。在某些情形下,在这个装置中唯一的动力中断是为了改变模式。在某些实施例中,另一优点在于通过具有那三种模式,范围高于传统齿轮箱,这改进了车辆的总体效率。在某些实施例中,设备允许利用最少数量的制动器在连续式无级变速传动(CVT)模式、无限式无级变速传动(IVT)模式、组合的IVT/CVT模式之间进行模式转换。

在某些实施例中,简单地通过接合一个离合器和释放另一个离合器来进行在三种模式之间的转变。在某些实施例中,这个装置能连续地改变其比例,以根据消耗量或动力目标提供该发动机可实现的最佳比例。在某些情形下,在手动或自动传动装置中,仅可以提供某些预定和离散比例并且需要中断动力传输来转换比例。在某些实施例下,在这个装置中唯一中断动力就是为了改变模式。在某些实施例中,另一优点在于通过具有那三种模式,范围高于传统齿轮箱,这改进了效率。在某些实施例中,另一优点在于拉威娜式行星齿轮系是紧凑系统。在某些实施例中,设备允许利用最少数量的制动器在连续式无级变速传动(CVT)模式、无限式无级变速传动模式(IVT)和组合的IVT/CVT模式之间进行模式转换。

在汽车50中,CVT 503用于替换传统传动装置并且位于发动机500与差速器502之间。在某些情形下,扭转阻尼器501引入于发动机500与拉威娜式行星齿轮系511之间,如图7所示。配置1f/(图7)使用拉威娜式行星齿轮系(511),然后连接到变速机构(512)。在某些实施例中,变速机构输出齿圈(520)然后连接到末级驱动器(522)和差速器。在某些实施例中,这种配置包括三个制动离合器,一个用于IVT模式(513);一个用于CVT模式(514)和一个用于IVT/CVT模式(515),其中变速机构输入齿圈(519)和变速机构行星架(521)都被驱动。在某些实施例中,这种配置的中央部分是上文所描述的变速机构。在某些实施例中,在变速机构的每一侧上的球斜道提供传递扭矩必需的夹持力。
在某些实施例中,拉威娜式行星齿轮系(511)的输出(516)连接到变速机构输入齿圈(519)。在某些实施例中,通过采用制动器(513),在IVT模式,将输出(516)太阳轮连接到外壳。在某些实施例中,该系统(511)的行星架(518)然后连接到变速机构的行星架。在某些实施例中,通过采用制动器(514),在CVT模式下,行星架(318)连接到外壳。在某些实施例中,在IVT/CVT模式下,通过采用制动器(515),行星齿轮系统的齿圈(517)连接到外壳,因此,使得变速机构输入齿圈(519)和变速机构行星架(521)都被驱动。在某些实施例中,关于速度,这种IVT/CVT模式位于IVT模式与CVT模式之间。在某些实施例中,总比是拉威娜式行星齿轮系传动比、变速机构传动比和末级驱动比的乘积。在某些实施例中,由变速机构的IVT模式实现了停车、很低车辆速度和倒车。
在某些实施例中,简单地通过接合一个离合器和释放其它离合器来进行在三种模式之间的转变。在某些实施例中,这个装置能连续地改变其比例,以根据消耗量或动力目标提供该发动机可实现的最佳比例。在某些情形下,在手动或自动传动装置中,仅可以提供某些预定和离散比例并且需要中断动力传输来转换比例。在某些实施例下,在这个装置中唯一中断动力就是为了改变模式。在某些实施例中,另一优点在于通过具有那三种模式,范围高于传统齿轮箱,这改进了效率。在某些实施例中,另一优点在于拉威娜式行星齿轮系是紧凑系统。在某些实施例中,设备允许利用最少数量的制动器在连续式无级变速传动(CVT)模式、无限式无级变速传动(IVT)模式和组合的IVT/CVT模式之间进行模式转换。
构思1g/
在汽车60中,CVT 603用于替换传统传动装置并且位于发动机600与差速器602之间。在某些情形下,扭转阻尼器601引入于发动机600与行星齿轮系611之间,如图8所示。配置1g/(图8)使用拉威娜式行星齿轮系(611),然后连接到变速机构(612)。在某些实施例中,变速机构输出连接到额外的行星齿轮系(613)。在某些实施例中,通过采用离合器(616)将其太阳轮与行星架锁定在一起而将这个行星齿轮系(613)锁定为以1:1比例转动。在某些实施例中,通过采用超速制动器(617)将行星齿轮系的太阳轮锁定到地面来具有更大范围来实现速度增加。在某些实施例中,这个行星齿轮系的齿圈然后连接到末级驱动器和差速器。在某些实施例中,变速机构的第二齿圈连接到第三行星齿轮系的行星架。在某些实施例中,这个配置包括三个制动器,一个用于IVT模式(615),一个用于CVT模式(614)并且一个用于施加超速传动比(617)。在某些实施例中,这种配置包括离合器(616),以通过使超速行星齿轮系(613)设置为1:1比例而绕过超速行星齿轮系(613)。在某些实施例中,这种配置的中央部分是上文所描述的变速机构。在某些实施例中,在变速机构的每一侧上的球斜道提供传递扭矩必需的夹持力。
在某些实施例中,输入行星齿轮系的齿圈连接到变速机构的输入齿圈。在某些实施例中,通过采用IVT制动器(615),在IVT模式下,输入行星齿轮系的齿圈连接到外壳。在某些实施例中,通过采用CVT制动器(614),在CVT模式下,输入行星齿轮系的行星架连接到外壳。在某些实施例中,输入行星齿轮系的行星架连接到变速机构的行星架。在某些实施例中,总比例通常是输入行星齿轮系传动比、变速机构传动比、输出行星齿轮系(613)传动比和末级驱动比之乘积。在某些实施例中,由变速机构的IVT模式实现了停车、很低车辆速度和倒车。
在某些实施例中,简单地通过释放一个离合器和闭合另一个离合器来进行在两种模式(CVT与IVT)之间的转变。而且,输出行星齿轮系的离合器(616)可用于选择输出行星齿轮系中的比例1:1。并且可以选择超速制动器来提供超速传动比。在任何时刻,在这些超速制动器和直接驱动离合器中的仅一个必须被接合。简单地通过释放一个并且接合另一个来实现这两个额外比例之间的转变。在某些实施例中,这个装置能连续地改变其比例,以根据消耗量或动力目标提供该发动机可实现的最佳比例。在某些情形下,在手动或自动传动装置中,仅可以提供某些预定和离散比例并且需要中断动力传输来转换比例。在某些实施例下,在这个装置中唯一中断动力就是为了改变模式。其它优点包括(但不限于):小末级驱动(以一个步骤,无需副轴)和该系统的成本效益。在某些实施例中,通过添加第三行星齿轮系,范围高于传统齿轮箱,这改进了车辆的总体效率。在某些实施例中,设备允许利用最少数量的制动器在连续式无级变速传动(CVT)模式与无限式无级变速传动(IVT)模式之间进行模式转换。
