Description

一种减速离合器离合驱动装置 技术领域
本发明涉及洗衣机领域,尤其是一种减速离合器离合驱动装置。
背景技术
现有技术如市场上的洗衣机有的为减速离合器与单相异步电机并排安装,通过皮带轮与皮带传动。该类减速离合器的效率低,噪声大,实用性较差,且传动部分故障率较高;因而有关技术人员提出了电机与离合器同轴的技术方案。如专利号为ZL00234747.4公开了无刷电机直接驱动的洗衣机减速离合器,该专利采用无刷电机直接驱动洗衣机离合器,解决了单相异步电机效率低,提高了能效,但该结构电机的连接复杂,只能实现普通洗涤方式,主体部件连接零件较多,且对离合器安装精度要求过高,并且其存在故障率高的缺点,因此该专利技术方案不适合批量生产产品。
如申请号为CN201120257375.8的中国专利,公开一种洗衣机仿生手搓变频减速离合器,其包括相配装的下壳体和输入轴,下壳体安装有直流无刷电机定子,输入轴的端部连接有直流无刷电机外转子,直流无刷电机定子位于直流无刷电机外转子的内腔中,输入轴配装有由轴套、离合轴、离合滑块和复位弹簧组成的滑动离合机构;轴套套装在输入轴上,离合轴位于轴套上方转动套装在输入轴上,轴套和离合轴均制有外周花键,离合滑块制有的内周导向花键与轴套和离合轴的外周花键滑动相配接,复位弹簧压配在离合滑块外周制有的圆环凸台上并且离合滑块连接有离合控制机构。但是离合控制机构复杂,控制繁琐。
现有的离合轴套或者离合滑块有的是由拨叉与离合簧相配合地控制其上下移动,而拨叉是通过旋转销直接安装在减速离合器的下壳体,以实现对离合轴套的控制。现有技术中多是使用牵引电机通过绳索对拨叉的一端进行牵引,另一端控制离合轴套或者离合滑块上下移动,牵引电机多安装在外桶底部,但是上述控制离合轴套上下移动的方法精准率低,故障率高,且占用空间较大,部件集成率低。

本发明所述为应用在洗衣机中的减速离合器离合驱动装置,如图1所示,所述减速离合器包括:由转子17和定子18构成的外转子电机,与转子17固定连接的输入轴15;所述的输入轴15经轴承可相对轴向旋转地套装在输入轴套16内;减速离合器外壳与转子17之间设置有离合轴套14;所述的离合轴套14可沿轴向上下滑动地安装在输入轴套16上,不可周向相对旋转;离合轴套14与减速离合器外壳下端之间设置有复位弹簧;离合轴套14在离合驱动装置的作用下,离合轴套14上下滑动地在第一位置与第二位置之间切换,输出轴30为波轮轴,输出轴套31为脱水轴。
当离合轴套14处于第一位置时,输入轴套16经离合轴套14与减速离合器外壳下端相连接并相对固定,此状态为洗涤状态。
在离合轴套14处于第二位置时,转子17经离合轴套14带动输入轴套16旋转,此状态为脱水状态。

实施例一
如图2-5所示,本实施例所述一种减速离合器离合驱动装置,包括驱动电机1、驱动轮2和拨叉杆3,驱动轮1安装在驱动电机1的电机轴上,驱动轮2圆周设有支撑面,支撑面在轴向上有高度差,拨叉杆3为杠杆结构,中部设有固定支点,拨叉杆3头部为拨叉6,拨叉6位于离合轴套14的下方,与复位弹簧一起控制离合轴套14的上下移动,拨叉杆3尾部为驱动端7,驱动端7设有滑动接触面,和支撑面滑动配合;驱动电机1带动驱动轮2转动,拨叉杆尾部的驱动端7在支撑面上相对滑动,尾部驱动端7高度变化带动拨叉杆头部拨叉6高度变化,头部拨叉6和复位弹簧一起作用带动离合轴套14上下移动。驱动轮2直接安装在驱动电机1的电机轴上,驱动轮2轴线与离合轴套14轴线平行,驱动轮2轴向静止,周向转动,拨叉杆3周向静止,驱动轮2周向转动时,支撑在驱动轮2支撑面的拨叉杆3尾部的驱动端7的高度随着支撑面转动时离合轴套轴向高度的变化而变化,拨叉杆3尾部驱动端7高度变化,带动拨叉杆3头部拨叉6的高度相应变化,从而带动离合轴套14的移动。该种离合驱动装置结构简单,驱动可靠性高,安装方便,模块集成化程度高。
所述驱动电机为步进电机,给一个脉冲信号,驱动电机轴转过180°,拨叉杆3尾部驱动端7由最高位置移动到最低位置,或者由最低位置移动到最高位置,驱动电机再转过180°,拨叉杆3尾部驱动端7由最低位置移动到最高位置,或者由最高位置移动到最低位置。
离合轴套14在拨叉6和复位弹簧的驱动下沿输入轴套16上下移动,移动到最下部时离合轴套14下端的花键齿与电机转子17上的花键齿啮合,输入轴15和输入轴套16同速同向转动,带动波轮轴和脱水轴同速同向转动,此时为脱水状态,离合轴套14上下移动到最上部时,上端的花键齿与减速离合器外壳或者固定支架12上的花键齿啮合,输入轴套16周向不能转动,输入轴15转动经减速离合器驱动波轮轴和脱水轴反向转动,形成双动力洗,或者脱水轴不转波轮轴转动,形成普通全自动洗,取决于减速离合器内部的轮系的设置,此时为洗涤状态。
本实施例所述驱动轮2包括一圆柱本体4,圆柱本体4至少部分圆周面沿径向向外延伸形成一弧形的凸出部5,凸出部5轴向的一个表面为支撑面,所述支撑面包括沿圆周方向顺次连接的倾斜的第一过渡面8、最高支撑面9和与第一过渡面8反向倾斜的第二过渡面10。
所述拨叉杆3尾部驱动端7的端面为一弧形槽,该弧形槽与驱动轮的圆柱本体对应配合,能辅助限定拨叉杆周向的转动。运行过程更加平稳,降低对连接件的冲击。若拨叉杆3端部没有该弧形槽,驱动轮2转动时候,支撑面和拨叉尾部驱动端的一个侧面相对滑动,由于有摩擦力会带动拨叉杆有跟随支撑面移动的趋势,会对拨叉杆的固定部分的连接件造成冲击,连接件容易发生损坏,造成减速离合器故障。
所述拨叉杆3尾部驱动端的一个侧面与驱动轮2的支撑面接触,该接触面包括沿圆周方向顺次连接的倾斜的第三过渡面19、最高接触面20和与第三过渡面19反向倾斜的第四过渡面21。所述最高支撑面9和最高接触面20接触时为面接触,可避免接触时的应力集中对接触部分造成损坏,提高零部件的使用寿命。
可以选择的所述驱动轮2的端部的部分圆周面沿径向向外延伸形成凸出部5,其他圆周面为圆 柱本体4的圆周面,优选所述驱动轮2的端部的整个圆周面的1/3~2/3沿径向向外延伸形成凸出部5,其他圆周面为圆柱本体的圆周面,所述凸出部5的支撑面与拨叉杆3的驱动端7接触时,驱动拨叉杆移动,驱动轮2转动至拨叉杆3的驱动端的侧面与凸出部5上的支撑面脱离时,只有尾部驱动端的弧形槽与圆柱本体4的圆柱面接触时,对拨叉杆上下方向的并不起限位的作用,此时拨叉杆靠复位弹簧恢复原位。
如所述驱动轮2的端部的1/2圆周面沿径向向外延伸形成凸出部5,另外1/2圆周面为圆柱本体2的圆周面。或者所述驱动轮的端部的1/3圆周面沿径向向外延伸形成凸出部,另外2/3圆周面为圆柱本体的圆周面。或者所述驱动轮的端部的2/3圆周面沿径向向外延伸形成凸出部,另外1/3圆周面为圆柱本体的圆周面。
可以选择的所述驱动轮的端部的整个圆周面沿径向向外延伸形成凸出部,所述凸出部包括一最高支撑面和最低支撑面,所述最高支撑面和最低支撑面圆周方向间隔180°,最高支撑面和最低支撑面之间倾斜过渡。该种情况下,拨叉杆的复位弹簧始终起作用。
拨叉杆3为杠杆结构,中部设有固定支点,拨叉杆3的中部安装在一固定支架12上,构成转动副,所述固定支架12固定在减速离合器外壳13上,或者所述固定支架12与减速离合器外壳13一体设置。优选固定支架12固定在减速离合器外壳13上,这样在固定支架12与拨叉杆3铰接的地方发生故障后只需更换固定支架12即可,不用将减速离合器外壳13整体更换。
所述拨叉杆3中部设有第一安装孔,所述固定支架相应位置设有第二安装孔,安装孔配合通过一旋转销铰接,形成拨叉杆3的固定支点,所述的旋转销上还设有为拨叉杆提供复位作用力的扭簧,该扭簧即为拨叉杆的复位弹簧,优选所述固定支点位于拨叉杆3中部靠近驱动端7一侧。这样驱动端7较小行程的移动就可得到头部较大行程的移动。
所述驱动轮2的凸出部5的轴向的上表面为支撑面,所述拨叉杆3的尾部驱动端7的下表面为与支撑面接触的接触面,所述支撑面包括向上倾斜第一过渡面8、最高支撑面9和斜向下的第二过渡面10,所述接触面包括斜向下的第三过渡面19、最高接触面20和斜向上的第四过渡面21。
当驱动轮2的转动带动离合轴套14处于第二位置时,最高支撑面9将拨叉杆3的尾部的驱动端7向上顶起,拨叉杆的头部拨叉6向下移动,对离合轴套14轴向的限位作用消失,离合轴套14在复位弹簧和重力的作用向下移动。驱动轮转动180度,驱动轮2的转动带动离合轴套14处于第一位置时,复位弹簧处于压缩状态,拨叉杆的尾部驱动端处于自由状态,或者最低支撑面与最高接触面接触,拨叉在自身扭簧的作用下,尾部驱动端7向下移动,头部拨叉向上移动,拨叉杆3的头部拨叉6将离合轴套14顶起。
所述驱动轮2的凸出部5的轴向的下表面为支撑面,所述拨叉杆3的尾部驱动端7的上表面为与支撑面接触的接触面,所述支撑面包括向下倾斜第一过渡面8、最高支撑面9和斜向上的第二过渡面10,所述接触面包括斜向上的第三过渡面19、最高接触面20和斜向下的第四过渡面21。
驱动轮2的转动,最高支撑面9将拨叉杆3的尾部驱动端7向下压下,拨叉杆3的头部拨叉向上移动,将离合轴套14顶起,驱动轮2转动180度,拨叉杆3的尾部驱动端7只有弧形槽与驱动轮配合,轴向方向上拨叉杆的尾部驱动端7处于自由状态,或者最低支撑面与最高接触面接触,拨叉杆3在自身扭簧的作用下,尾部驱动端7向上移动,头部向下移动,离合轴套14在复位弹簧和重力的作用向下移动。

离合轴套14在拨叉6和复位弹簧的驱动下沿输入轴套16上下移动,移动到最下部时离合轴套14下端的花键齿与电机转子17上的花键齿啮合,输入轴15和输入轴套16同速同向转动,带动波轮轴和脱水轴同速同向转动,此时为脱水状态,离合轴套14上下移动到最上部时,上端的花键齿与减速离合器外壳或者固定支架12上的花键齿啮合,输入轴套16周向不能转动,输入轴15转动经减速离合器驱动波轮轴和脱水轴反向转动,形成双动力洗,或者脱水轴不转波轮轴转动,形成普通全自动洗,取决于减速离合器内部的轮系的设置,此时为洗涤状态。
驱动轮2直接安装在驱动电机1的电机轴上,驱动轮2轴线与离合轴套14轴线平行,驱动轮2轴向静止,周向转动,拨叉杆3周向静止,驱动轮2周向转动时,支撑在驱动轮2支撑滑道的拨叉杆3尾部的驱动端7的高度随着支撑滑道转动时轴向高度的变化而变化,拨叉杆3尾部驱动端7高度变化,带动拨叉杆3头部拨叉6的高度相应变化,从而带动离合轴套14的移动。该种离合驱动装置结构简单,驱动可靠性高,安装方便,模块集成化程度高。
驱动轮2包括一圆柱本体4,圆柱本体4圆周面上沿径向向内凹陷形成一圈轴向高度渐变的凹槽23,该凹槽23为支撑滑道,所述支撑滑道轴向的高度变化圆滑过渡。支撑滑道包括沿圆周方向顺次连接的最低支撑面、倾斜的第一过渡面、最高支撑面和与第一过渡面反向倾斜的第二过渡面,各面连接处圆滑过渡。驱动轮2转动时,拨叉杆3的尾部的驱动端7在支撑滑道内,随着支撑滑道轴向高度的变化,拨叉杆3的尾部的驱动端7轴向高度变化。
所述最高支撑面和最低支撑面圆周方向间隔180°。所述驱动电机为步进电机,给一个脉冲信号,驱动电机轴转过180°,拨叉杆3尾部驱动端7由最高位置移动到最低位置,或者由最低位置移动到最高位置,驱动电机再转过180°,拨叉杆3尾部驱动端7由最低位置移动到最高位置,或者由最高位置移动到最低位置。每次状态转化时,驱动电机1转动的角度相同,当然也可以设置成间隔不同的角度,只是驱动电机每次转动的角度不同。

所述拨叉杆3尾部驱动端7设有一个滚动轴承34,该滚动轴承34伸入驱动轮2的支撑滑道内,这样驱动端7和支撑滑道可以平稳连接,增加滚动轴承34还可以减少阻滞,动作灵活,减小磨损。
所述驱动电机1的电机轴的轴线与离合轴套14的轴线平行,所述驱动电机1安装在减速离合器外壳13上,或者所述驱动电机安装在减速离合器安装板上(该种情况图中未示出)。与以往牵引电机安装在外桶底部的技术方案,本发明所述减速离合器中驱动电机1之间安装在减速离合器外壳上或者减速离合器安装板上结构紧凑,占用空间小。

本实施例所述拨叉杆3不需要设置拨叉杆3的复位弹簧,驱动轮的凹槽可以驱动拨叉杆3尾部的驱动端7的上下两侧,可驱动拨叉杆3尾部的驱动端7向上移动和向下移动。可节省一个零件结构,可简化一步装配的过程,节省材料成本。
所述拨叉杆3尾部具有一弧形槽,该弧形槽与驱动轮的圆柱本体4配合,弧形槽中部垂直于弧形槽向外延伸,伸入驱动轮2的支撑滑道内,与支撑滑道活动连接。运行过程更加平稳,降低对连接件的冲击。若拨叉杆3端部没有该弧形槽,驱动轮2转动时候,支撑面和拨叉尾部驱动端的一个侧面相对滑动,由于有摩擦力会带动拨叉杆3有跟随支撑滑道移动的趋势,会对拨叉杆3的固定部分的连接件造成冲击,连接件容易发生损坏,造成减速离合器故障。

拨叉杆3为杠杆结构,中部设有固定支点,拨叉杆3的中部安装在一固定支架12上,构成转动副,所述固定支架12固定在减速离合器外壳13上,或者所述固定支架12与减速离合器外壳13一体设置。优选固定支架12固定在减速离合器外壳13上,这样在固定支架12与拨叉杆3铰接的地方发生故障后只需更换固定支架12即可,不用将减速离合器外壳13整体更换。
所述拨叉杆3中部设有第一安装孔,所述固定支架相应位置设有第二安装孔,安装孔配合通过一旋转销铰接,形成拨叉杆3的固定支点,所述的旋转销上还设有为拨叉杆提供复位作用力的扭簧, 该扭簧即为拨叉杆的复位弹簧,优选所述固定支点位于拨叉杆3中部靠近驱动端7一侧。这样驱动端7较小行程的移动就可得到头部较大行程的移动。
凸轮26位于拨叉杆3尾部驱动端7的下方,所述拨叉杆3尾部驱动端7的下侧面设有卡槽,该卡槽支撑在凸轮圆周面上,所述拨叉杆设有提供使拨叉杆头部上移的复位作用力的扭簧。
凸轮26转动,与拨叉杆3的尾部驱动端7接触的凸轮26的圆周面的半径逐渐变大,将拨叉杆3的尾部驱动端7向下压下,拨叉杆3的头部拨叉向上移动,将离合轴套14顶起,直至凸轮26的最大半径圆周面,再转动时,与拨叉杆3的尾部驱动端7接触的凸轮26的圆周面的半径逐渐变小,逐渐远离拨叉杆3的尾部驱动端7,对拨叉杆3的尾部驱动端7的限位作用逐渐消失,拨叉杆3在自身扭簧的作用下,尾部驱动端7向上移动,头部向下移动,离合轴套14在复位弹簧和重力的作用向下移动。

实施例四
如图10、图11所示,本实施例所述一种减速离合器离合驱动装置,包括驱动电机1、驱动轮2和拨叉杆3,所述驱动轮2的轴线与离合轴套14的轴线垂直,所述驱动轮2的端面偏心设有支撑杆27,所述拨叉杆3为杠杆结构,中部设有固定支点,拨叉杆3头部为拨叉6,与复位弹簧一起控制离合轴套的上下移动,拨叉杆3尾部为驱动端7,支撑在支撑杆27上,所述驱动轮2转动,支撑杆27在离合轴套轴线方向上高度变化,带动拨叉杆3尾部驱动端7高度变化,带动拨叉杆3头部拨叉6高度相应变化,头部拨叉6和复位弹簧一起作用带动离合轴套的上下移动。
离合轴套14在拨叉6的驱动下沿输入轴套16上下移动,移动到最下部时离合轴套14下端的花键齿与电机转子17上的花键齿啮合,输入轴15和输入轴套16同速同向转动,带动波轮轴和脱水轴同速同向转动,此时为脱水状态,离合轴套14上下移动到最上部时,上端的花键齿与减速离合器外壳或者固定支架12上的花键齿啮合,输入轴套16周向不能转动,输入轴15转动经减速离合器驱动波轮轴和脱水轴反向转动,形成双动力洗,或者脱水轴不转波轮轴转动,形成普通全自动洗,取决于减速离合器内部的轮系的设置,此时为洗涤状态。
驱动电机1的电机轴的轴线与所述离合轴套14的轴线垂直,所述驱动轮2的一端直接安装在驱动电机1的电机轴上,驱动轮2的另一端面偏心设有支撑杆27。驱动轮2轴向静止,周向转动,拨叉杆3周向静止,驱动轮2周向转动时,支撑在驱动轮2支撑杆的拨叉杆3尾部的驱动端7的高度随着支撑杆转动时离合轴套14轴向高度的变化而变化,拨叉杆3尾部驱动端7高度变化,带动拨叉杆3头部拨叉6的高度相应变化,从而带动离合轴套14的移动。该种离合驱动装置结构简单,驱动 可靠性高,安装方便,模块集成化程度高。
拨叉杆3尾部驱动端7的端面上设有一内凹的直线滑槽28,该滑槽28与拨叉杆3转动轴平行,所述支撑杆27伸入拨叉杆的滑槽28内。驱动轮2转动时,支撑杆27绕驱动轮2的轴心转动,而支撑杆27只能在滑槽28内滑动,所以驱动拨叉杆3绕转轴转动,将转动转化为上下往复平动。
优选的可以在支撑杆27的端部设置滚动轴承34,该滚动轴承34伸入拨叉杆3尾部驱动端7的滑槽28内,这样支撑杆27和滑槽28可以平稳连接,增加滚动轴承34还可以减少阻滞,动作灵活。
所述滑槽28的长度大于所述支撑杆偏心距的2倍,这样可保证驱动轮转180°后保证支撑杆27沿滑槽28方向的行程,滑槽28与支撑杆27间隙太小支撑杆27在滑槽28内部滑动不顺畅,摩擦较大,间隙太大,方向改变时的冲击较大,所述滑槽的宽度为所述支撑杆27直径的1.05~1.2倍。
所述驱动电机1固定安装在减速离合器外壳13上,或者所述驱动电机固定安装在减速离合器安装板上。优选安装在减速离合器安装板上,与以往牵引电机安装在外桶底部的技术方案,本发明所述减速离合器中驱动电机1之间安装在减速离合器外壳上或者减速离合器安装板上结构紧凑,占用空间小。
拨叉杆3为杠杆结构,中部设有固定支点,拨叉杆3的中部安装在一固定支架12上,构成转动副,所述固定支架12固定在减速离合器外壳13上,或者所述固定支架12与减速离合器外壳13一体设置。优选固定支架12固定在减速离合器外壳13上,这样在固定支架12与拨叉杆3铰接的地方发生故障后只需更换固定支架12即可,不用将减速离合器外壳13整体更换。
所述拨叉杆3中部设有第一安装孔,所述固定支架相应位置设有第二安装孔,安装孔配合通过一旋转销铰接,形成拨叉杆3的固定支点,所述的旋转销上还可以设有为拨叉杆提供复位作用力的扭簧,该扭簧即为拨叉杆的复位弹簧,优选所述固定支点位于拨叉杆3中部靠近驱动端7一侧。这样驱动端7较小行程的移动就可得到头部较大行程的移动。
本实施例所述拨叉杆3可以不设置拨叉杆3的复位弹簧,驱动轮的支撑杆27可以驱动拨叉杆3尾部的驱动端7滑槽28的上下两侧,可驱动拨叉杆3尾部的驱动端7向上移动和向下移动。可节省一个零件结构,可简化一步装配的过程,大批量生产时还能节省成本。
驱动轮2的转动,驱动轮2的支撑杆27绕驱动轮2的轴心转动,支撑杆27伸入到拨叉杆3的尾部的驱动端7的滑槽28内,在滑槽28内二者相对滑动,若支撑杆27为沿离合轴套14的轴向向上运动,则将拨叉杆3的尾部的驱动端7向上顶起,拨叉杆的头部拨叉6向下移动,与离合轴套14的凸台远离,对离合轴套14轴向的限位作用消失,离合轴套14在复位弹簧和重力的作用向下移动,驱动轮2继续转动,支撑杆27为沿离合轴套14的轴向向下运动,将拨叉杆3的尾部的驱动端7向下压下,头部拨叉向上移动,拨叉杆3的头部拨叉6将离合轴套14顶起。完成位置状态的切换。
