本实施例提供了一种驻车及离合器共用控制装置,参阅图1-2,本实施 例的驻车及离合器共用控制装置,包括驻车机构、离合器机构和电机51;驻车机构包括定位板52、转鼓523、弹性***54和若干定位槽524,转鼓523与定位板52联动连接,定位槽524设于定位板52上,定位板52在电机51的带动下旋转,弹性***54与定位槽524相互作用,转鼓523能够转动至驻车锁止、驻车脱开、离合器接合和离合器脱开对应的位置;离合器机构包括离合器拨叉组件和设于离合器拨叉组件上的拨叉驱动凸轮551,拨叉驱动凸轮551旋转时带动离合器拨叉组件轴向移动;转鼓523上设有凸轮槽522,凸轮槽522包括啮合旋转槽和垂直于轴线的直槽;当转鼓523在驻车锁止与驻车脱开的位置之间旋转时,拨叉驱动凸轮551位于直槽内,直槽不与拨叉驱动凸轮551相啮合,因此拨叉组件不产生轴向运动;当转鼓523在驻车脱开与离合器接合的位置之间旋转时,拨叉驱动凸轮551位于啮合旋转槽内,所啮合旋转槽与拨叉驱动凸轮551相啮合,驱动离合器拨叉组件轴向运动。
作为一种具体的实施方式,拨叉驱动凸轮551通过外拨叉套553与离合器拨叉组件连接,离合器拨叉组件包括拨叉导向轴77、外拨叉55和内拨叉76,内拨叉76套设于拨叉导向轴77上,外拨叉55套设于内拨叉76上,外拨叉55上设有固定销552,内拨叉76上开设有轴向槽761,固定销552在轴向槽761内滑动。外拨叉55与内拨叉76之间还设有拨叉弹簧75,外拨叉55通过拨叉弹簧75驱动内拨叉76。
作为一种具体的实施方式,离合器机构还包括离合器输入轴11、离合器滑动齿套71和离合器齿毂72,离合器齿毂72上设有与离合器输出轴84联接的齿毂花键722,离合器滑动齿套71套设于离合器齿毂72上;离合器输入轴11上设有离合器犬齿113;离合器滑动齿套71通过拨叉脚762与拨叉导向轴77连接,拨叉脚762设于离合器滑动齿套71的外周;离合器滑动齿套71上设有内齿711和与内拨叉76配合的周向沟槽712,离合器滑动齿套71在拨叉弹簧75作用下***离合器犬齿113的齿隙,离合器齿毂72上设有传动齿721,内齿711分别与离合器犬齿113和传动齿721啮合。拨叉组件经过一预压的拨叉弹簧75来控制离合器滑动齿套71的挂档运动。即使离合器两端转速差较大而无法接合,或离合器两端齿端对上时,拨叉 输入端也可运动到位并被定位在接合位置。压缩了的拨叉弹簧75使离合器滑动齿套71一直压向离合器犬齿113,保证离合器在转速差降低后离合器滑动齿套71与离合器输入轴上离合器犬齿113接合。当需要脱开离合器时,外拨叉55通过机械联接,如传动销,直接将内拨叉76拖出接合位置,使离合器断开。
进一步地,在所述内齿711端部还设有倒角713,以便于离合器滑动齿套71与离合器犬齿113接合。
本实施例中的驻车及离合器共用控制装置,在驻车机构的定位板52上加一转鼓523,转鼓523上带有凸轮槽522,凸轮槽522与拨叉驱动凸轮551配合,定位板52在作驻车旋转运动时,凸轮槽522不产生轴向位移,当定位板52作离合器控制运动时,凸轮槽522驱动离合器拨叉组件轴向运动,使离合器接合或脱开。在定位板52上开有若干个定位槽524,这些定位槽524与弹性***54相作用,将定位板52和离合器拨叉组件锁在驻车、电动或发动机直驱的位置,车辆行驶时电机51可断电,从而节省了现有湿式离合器液压泵的功耗、提高了变速器效率。
作为一种具体的实施方式,驻车机构还包括驻车致动杆56,驻车致动杆56的端部设有驱动弯头561;定位板52上开设有铰孔526,驱动弯头561与铰孔526铰接,当定位板52旋转时,将驻车致动杆56推向或拖出驻车锁止的位置。

作为一种具体的实施方式,导向板57上设有棘爪限位垫板571,驻车棘爪58上还还设有对驻车棘爪58起限位作用的驻车棘爪限位面584。
作为一种具体的实施方式,定位板52通过回转轴53与转鼓523连接,定位板52和转鼓523均通过固定销531与回转轴53连接,定位板52、回转轴53和转鼓523均可绕固定轴孔621旋转。
作为一种具体的实施方式,电机51的输出轴上设有驱动齿轮511,定位板52上设有齿弧521,驱动齿轮511与齿弧521啮合。
作为一种具体的实施方式,离合器机构还包括轴承支撑组件4和壳体6,轴承支撑组件4将离合器回转部件支撑在壳体6上。
进一步地,轴承支撑组件4包括滚柱轴承41、第一球轴承42、止推轴承43和第二球轴承45。
进一步地,壳体6包括前壳体62、后壳体63以及用于盖合前壳体62、后壳体63的盖板61。
本实施例中的驻车及离合器共用控制装置尤其适合图3所示混合动力汽车变速器。图中,ICE代表发动机,C0代表离合器,P表示驻车,P1表示P1电机,P3表示P3电机。发动机1的输出轴经发动机减振器12和离合器输入轴11,并通过连接腹板13,联接到P1发电机2的转子上,离合器输入轴11上设有花键111,用于与发动机减振器12连接。城市工况驱动的P3电机3的转子31与变速器输入轴33固定连接。离合器7用来控制离合器输出轴84与发动机输出轴之间的通和断。在电池电量充足和城市路况下,离合器7断开,P3电动机3经变速器输出轴33、齿轮对34/91、95/96、差速器97驱动车轮20,齿轮对34/91、95/96总速比在9左右,可有效放大P3电动机3的扭矩,提高低速驱动的动力性。高速时离合器7接合,发动机1经离合器7、离合器输出轴84、齿轮对83/93、95/96、差速器97驱动车轮20,齿轮对83/93、95/96总速比在3左右,能够保证高速时发动机高效直接驱动。
需要说明的是,本实施例中的驻车及离合器共用控制装置,并不限于适用采用平行轴机构的变速器,如果P3电机转子联到行星齿轮机构的太阳轮,行星架输出,离合器输出轴84就可直接联到行星架。对于其他使用离 合器和驻车机构的混合动力汽车均可采用本实施例中的驻车及离合器共用控制装置,以提高变速器效率,并降低制造成本。
如图3所示的混合动力汽车变速器,驻车的工作过程如下:继续参阅图1-3以及图4,启动电机51沿逆时针方向旋转,驱动定位板52顺时针方向旋转,推动驻车致动杆56右移直到驻车锁止位置,到位后定位板52由弹性***54定位在驻车锁止位置,实现P挡驻车,电机51可断电。在导向板57的作用下驻车致动杆56经弹簧563和契块564将驻车棘爪58压向驻车棘轮59。一旦驻车棘轮59转速慢到设定值,驻车棘爪58上爪齿583就会进入驻车棘轮59上的齿隙,将驻车棘轮59锁止,车辆制动。
如图3所示的混合动力汽车变速器,驻车松开、电动汽车(EV)模式的工作过程如下:继续参阅图1-3以及图5,若要启动车辆,先必须松开驻车机构。此时启动电机51沿顺时针方向旋转,驱动定位板52逆时针方向旋转,铰孔526将驻车致动杆56拖出驻车锁止位置,弹性***54将定位板52定在D挡,即驻车脱开位置,电机51可断电。车辆可在EV模式下行驶。
如图3所示的混合动力汽车变速器,离合器接合、发动机直驱模式的工作过程如下:如图6所示,图中t表示时间,V表示转速,当需要发动机1直接驱动时,迅速用P1发电机2将离合器输入轴11的转速V
i拖到与离合器输出轴84转速V
o相近的转速,V
o是离合器输出轴84的转速,由车辆行驶速度确定。继续参阅图1-3以及图7,然后启动电机51沿顺时针方向旋转,驱动定位板52逆时针方向旋转约45°。当转鼓523在驻车脱开位和离合器接合位之间旋转时,拨叉驱动凸轮551在啮合旋转槽段内,转鼓523旋转会驱动拨叉驱动凸轮551轴向运动。如转鼓523逆时针旋转45°可迫使拨叉驱动凸轮551轴向右移约6mm。拨叉驱动凸轮551轴向位移带动外拨叉55轴向运动。外拨叉55上有固定销552,可在内拨叉76上轴向槽761中滑动。当外拨叉55向右运动时,固定销552在轴向槽761中滑动,不直接驱动内拨叉76。然而拨叉弹簧75将内拨叉76向右推进。如果离合器滑动齿套71上内齿711与离合器输入轴11上离合器犬齿113齿隙错开,离合器滑动齿套71无法右行,内拨叉76及离合器滑动齿套71将停止轴向运动, 离合器滑动齿套71将贴在离合器犬齿113端面滑动。由于拨叉弹簧75限制了离合器滑动齿套71与离合器犬齿113端面间接触力,避免了现有刚性换档拨叉大力挂档产生的冲击和磨损。
进一步地,为了减少摩擦阻力,拨叉驱动凸轮551上可加装滚动轴套。外拨叉55上固定销552既可以防止外拨叉55转动,又能在外拨叉55回程时将内拨叉76拖离接合位置。
若转速差V
o-V
i大于设计接合转速差(一般为20-50rpm),离合器滑动齿套71会与离合器输入轴11一直在齿端打滑。为了节省能耗,电机51可断电,外拨叉55可由弹性***54和定位槽524锁在如图7所示的接合位置。当定位板52转到接合位置后,继续控制P1发电机2转速以减小转速差V
o-V
i。当转速差小于或等于设计接合转速差时,离合器滑动齿套71的内齿711在拨叉弹簧75压力下***离合器犬齿113齿隙,并带动传动齿721同速运转,完成离合器接合过程。由于转速差较小,离合器接合过程产生的噪声也较现有大差速接合的犬齿离合器低。
如图3所示的混合动力汽车变速器,离合器脱开、电动汽车(EV)模式的工作过程如下:要脱离发动机1直接驱动时,启动电机51逆时针方向旋转,驱动定位板52顺时针方向旋转到脱开角度,凸轮槽522迫使外拨叉55左移到脱开位置,弹性***54将转鼓523和外拨叉55锁在脱开位置。
本发明另一实施例提供一种上述实施例中的驻车及离合器共用控制装置的操纵方法,包括以下步骤:启动电机51后,定位板52在电机51的带动下旋转,转鼓523分别转动至驻车锁止、驻车脱开、离合器接合和离合器脱开对应的位置,当转鼓523在驻车脱开与离合器接合的位置之间旋转时,拨叉驱动凸轮551位于啮合旋转槽内,啮合旋转槽与拨叉驱动凸轮551相啮合,拨叉驱动凸轮551旋转时带动离合器拨叉组件轴向移动;驻车锁止、驻车脱开、离合器接合或离合器脱开完成后,弹性***54与定位槽524相互作用,将定位板52定位后,电机51断电。
作为一种具体的实施方式,驻车机构还包括驻车致动杆56、导向板57、驻车棘爪58和与变速器输出轴连接的驻车棘轮59,导向板57安装于变速器箱体上,驻车棘爪58设于驻车致动杆56上;当转动转鼓523至驻车锁 止位置时,在导向板57的作用下驻车致动杆56将驻车棘爪58压向驻车棘轮59,驻车棘爪58上的爪齿583进入驻车棘轮59上的齿隙,将驻车棘轮59锁止。
作为一种具体的实施方式,驻车致动杆56的端部设有驱动弯头561,定位板52上开设有铰孔526,驱动弯头561与铰孔铰接526;当转鼓523处于驻车锁止位置时,沿与转动至驻车锁止位置相反的方向旋转定位板52,通过铰孔526将驻车致动杆56拖出驻车锁止位置。
作为一种具体的实施方式,离合器拨叉组件包括外拨叉55、内拨叉76和拨叉弹簧75,外拨叉55套设于内拨叉76上,外拨叉55通过拨叉弹簧75驱动内拨叉76;离合器机构还包括离合器输入轴11、离合器滑动齿套71和离合器齿毂72,离合器输入轴11上设有离合器犬齿113,离合器滑动齿套71上设有内齿711,离合器齿毂72上设有传动齿721;当转鼓523在驻车脱开位和离合器接合位之间旋转时,旋转拨叉驱动凸轮551带动外拨叉55轴向运动,外拨叉55通过拨叉弹簧75驱动内拨叉76,内拨叉76驱动离合器滑动齿套71***离合器犬齿113的齿隙,离合器滑动齿套71上的内齿711分别与离合器犬齿113和传动齿721啮合,带动传动齿721同速运转。
作为一种具体的实施方式,当转鼓523处于离合器接合的位置时,沿与离合器接合时相反的方向转动定位板52,使得外拨叉55轴向运动至离合器滑动齿套71上的内齿711与离合器犬齿113分离,弹性***54将转鼓523和外拨叉55定位在离合器脱开位置。
本发明的另一实施例还提供一种车辆,该车辆包括上述实施例中的驻车及离合器共用控制装置。

1、本发明的驻车及离合器共用控制装置,相比于现有技术中采用摩擦片湿式离合器,犬牙式离合器节省了摩擦片、液压油缸、液压泵、比例压力电磁阀和阀板等零部件的成本;离合器机构与驻车机构共用控制电机,功耗很小,由于转鼓可借助弹性***与定位槽定位,离合器接合后不需电机供电,从而节省了功耗、提高了变速器效率;
