Description
本申请涉及一种双保持架超越离合器，属于超越离合器技术领域。The present application relates to a double-cage overrunning clutch, belonging to the technical field of overrunning clutches.
目前，双保持架超越离合器一般包括内圈、外圈、楔块、内保持架、外保持架、波形弹簧和阻尼卡，例如，申请公布日为2015.01.28、申请公布号为CN112324816A的中国发明专利申请中公开了一种斜撑式超越离合器，如图1所示，该斜撑式超越离合器包括由内向外依次布置的内圈1、内保持架2、波形弹簧3、外保持架4及外圈5，在内圈1与外圈5之间布置有若干个楔块6，所有楔块6沿内圈1周向间隔分布，并且，所有楔块6对应安装在内保持架2、波形弹簧3及外保持架4的窗孔内，波形弹簧3的窗孔过梁上设有用于向各楔块6施加弹性作用力的弹性片，以迫使楔块6与内圈1的内滚道、外圈5的外滚道保持压力接触，实现超越离合器的正常工作。At present, a double cage overrunning clutch generally includes an inner ring, an outer ring, a wedge, an inner cage, an outer cage, a wave spring and a damping card. For example, a Chinese invention patent application with an application publication date of 2015.01.28 and an application publication number of CN112324816A discloses a diagonal brace overrunning clutch, as shown in FIG1 . The diagonal brace overrunning clutch includes an inner ring 1, an inner cage 2, a wave spring 3, an outer cage 4 and an outer ring 5 arranged in sequence from the inside to the outside. A plurality of wedges 6 are arranged between the inner ring 1 and the outer ring 5. All wedges 6 are distributed at intervals along the circumference of the inner ring 1, and all wedges 6 are correspondingly installed in the window holes of the inner cage 2, the wave spring 3 and the outer cage 4. An elastic sheet for applying an elastic force to each wedge 6 is provided on the window hole lintel of the wave spring 3, so as to force the wedge 6 to maintain pressure contact with the inner raceway of the inner ring 1 and the outer raceway of the outer ring 5, thereby realizing the normal operation of the overrunning clutch.
上述斜撑式超越离合器在使用时，内圈用于与主动件传动连接，在传扭状态下，楔块楔紧，内圈、内保持架、波形弹簧、楔块、外保持架及外圈相对固定装配在一起，驱动外圈转动，外圈作为动力输出部输出扭矩；在超越状态下，外圈转速超过内圈转速，楔块朝向与内圈滚道脱开的方向摆动，离合器处于超越状态。When the above-mentioned diagonal brace overrunning clutch is in use, the inner ring is used for transmission connection with the active part. In the torque transmission state, the wedge is wedged tightly, and the inner ring, inner retainer, wave spring, wedge, outer retainer and outer ring are relatively fixedly assembled together to drive the outer ring to rotate. The outer ring outputs torque as a power output part; in the overrunning state, the outer ring speed exceeds the inner ring speed, the wedge swings in the direction of disengagement from the inner ring raceway, and the clutch is in the overrunning state.
在上述斜撑式超越离合器的应用过程中存在一些问题，具体如下：在波形弹簧对各楔块施加弹性作用力的同时各楔块也会对波形弹簧施加反作用力，由于波形弹簧仅通过楔块穿过其上的窗孔来对其进行固定，在波形弹簧受到反作用力时，波形弹簧在周向上会发生转动，使得波形弹簧对各楔块施加的弹性作用力不均衡，导致各楔块在与内圈滚道脱开时同步性较差；同时，由于波形弹簧在受到反作用力时会发生转动，使得波形弹簧对各楔块的弹性作用力较小。There are some problems in the application process of the above-mentioned diagonal brace overrunning clutch, which are as follows: while the wave spring applies an elastic force to each wedge block, each wedge block also applies a reaction force to the wave spring. Since the wave spring is fixed only by the wedge block passing through the window hole thereon, when the wave spring is subjected to the reaction force, the wave spring will rotate in the circumferential direction, making the elastic force applied by the wave spring to each wedge block unbalanced, resulting in poor synchronization of each wedge block when disengaging from the inner ring raceway; at the same time, since the wave spring will rotate when subjected to the reaction force, the elastic force of the wave spring on each wedge block is relatively small.

In the torque transmission state, the wedge block is kept in a wedged state under the action of the elastic member, so that the inner ring and the outer ring of the clutch rotate synchronously; in the overrunning state, the wedge block swings under the action of the centrifugal force to overcome the elastic force, the wedge block is out of contact with the inner ring raceway, and the clutch is in the overrunning state. In the overrunning clutch provided in this embodiment, since the elastic member is fixed on the window hole lintel and corresponds to the wedge block one by one, when the elastic member is subjected to the reaction force of the wedge block, the elastic member will not move relatively and each elastic member is independently stressed, which ensures that the force of each wedge block is balanced and improves the synchronization when each wedge block is disengaged from the inner ring raceway. Moreover, since the elastic member is fixed on the window hole lintel of the retaining frame, the elastic member will not move after being subjected to the reaction force, thereby increasing the elastic force of the elastic member on the wedge block. Based on the above analysis, the double-retaining frame overrunning clutch provided by the present application is compared with the existing overrunning clutch. Since each wedge block has a higher synchronization when disengaging from the inner ring raceway, the switching speed when switching to the overrunning state is faster, thereby reducing the wear between the wedge block and the inner ring raceway; moreover, since the elastic member can provide a greater elastic force to the wedge block, the quality of the clutch is improved, thereby enabling the clutch to adapt to higher speed working conditions.

本申请中双保持架超越离合器的实施例1：Embodiment 1 of the double cage overrunning clutch in the present application:
如图2所示，本实施例提供的双保持架超越离合器(以下简称超越离合器)包括由内向外依次布置的内圈100、内保持架101、外保持架102及外圈109，在内圈100与外圈109之间布置有多个楔块110，各楔块110沿内圈100周向间隔分布，并且，所有楔块110对应安装在内保持架101和外保持架102的窗孔103内，内保持架101的窗孔过梁104
上固设有弹性件112，弹性件112与各楔块110一一对应，以对相应楔块110施加弹性作用力，楔块110在弹性作用力的作用下与超越离合器的内圈100和外圈109保持楔紧状态。As shown in FIG2 , the double cage overrunning clutch (hereinafter referred to as overrunning clutch) provided in this embodiment includes an inner ring 100, an inner cage 101, an outer cage 102 and an outer ring 109 arranged in sequence from the inside to the outside, and a plurality of wedges 110 are arranged between the inner ring 100 and the outer ring 109, and each wedge 110 is distributed at intervals along the circumference of the inner ring 100, and all the wedges 110 are correspondingly installed in the window holes 103 of the inner cage 101 and the outer cage 102, and the window hole lintel 104 of the inner cage 101 An elastic member 112 is fixedly provided thereon, and the elastic member 112 corresponds to each wedge block 110 one by one to apply an elastic force to the corresponding wedge block 110 . Under the action of the elastic force, the wedge block 110 maintains a wedging state with the inner ring 100 and the outer ring 109 of the overrunning clutch.
本实施例中，弹性件112包括安装部分和弹性支撑部分，弹性件112通过安装部分可拆固定在内保持架101上，具体地，如图2、图4和图5所示，弹性件112由弹性板折弯形成，具体地，本实施例中优选为弹性金属板，安装部分包括卡子113，弹性件112通过卡子113卡装固定在内保持架101的窗孔过梁104上。弹性支撑部分为弹性片114，在径向上，弹性片114向外弯折，以在径向上顶压在相应楔块110上朝向内侧的一端处，也即楔块110上靠近内圈100的一端处。In this embodiment, the elastic member 112 includes a mounting portion and an elastic support portion, and the elastic member 112 is detachably fixed to the inner retainer 101 through the mounting portion. Specifically, as shown in Figures 2, 4 and 5, the elastic member 112 is formed by bending an elastic plate, and specifically, in this embodiment, it is preferably an elastic metal plate. The mounting portion includes a clip 113, and the elastic member 112 is clamped and fixed to the window hole lintel 104 of the inner retainer 101 through the clip 113. The elastic support portion is an elastic sheet 114, and in the radial direction, the elastic sheet 114 is bent outward to press against the end of the corresponding wedge block 110 facing the inner side in the radial direction, that is, the end of the wedge block 110 close to the inner ring 100.
本实施例中，为防止弹性件112在轴向上发生窜动，如图5所示，内保持架101的窗孔过梁104上设有轴向限位槽105，在轴向上，轴向限位槽105的宽度与卡子113的宽度相适配，以在卡子113卡装在轴向限位槽105中时对卡子113的位置进行限位。另外，为防止止弹性件112在径向上发生窜动，如图4所示，卡子113包括U形卡槽，U形卡槽由弹性板件弯折形成，U形卡槽的槽壁相向倾斜延伸，使得U形卡槽的槽口为收口。在安装卡子时，U形卡槽的槽口先张开供窗孔横梁进入到U形卡槽中，接着U形卡槽的槽口在弹性力的作用下恢复为收口状，完成卡子的卡装。In this embodiment, in order to prevent the elastic member 112 from moving in the axial direction, as shown in FIG5 , an axial limiting groove 105 is provided on the window hole beam 104 of the inner retainer 101. In the axial direction, the width of the axial limiting groove 105 matches the width of the clip 113, so as to limit the position of the clip 113 when the clip 113 is clamped in the axial limiting groove 105. In addition, in order to prevent the elastic member 112 from moving in the radial direction, as shown in FIG4 , the clip 113 includes a U-shaped clamping groove, which is formed by bending an elastic plate, and the groove walls of the U-shaped clamping groove extend toward each other, so that the notch of the U-shaped clamping groove is closed. When installing the clamp, the notch of the U-shaped clamping groove is first opened to allow the window hole beam to enter the U-shaped clamping groove, and then the notch of the U-shaped clamping groove is restored to a closed shape under the action of the elastic force, and the clamping of the clamp is completed.
本实施例中，为保证外保持架102始终与外圈109同步转动，如图3所示，外保持架102轴向一端的凸缘106上设有缺口107，在外保持架102的周向上，缺口107分别位于外保持架102上窗孔103横梁的两侧，以使两缺口之间的凸缘106段与相应窗孔103横梁共同形成T形结构108，在外保持架102的径向上，T形结构108向外偏摆以与外圈109保持摩擦接触。T形结构108的设置可以代替外阻尼卡，当超越离合器迅速加、减速时，T形结构108克服外保持架102和楔块110的惯性力，以保证超越离合器的啮合和脱开更迅速，而且还可以减少楔块110的磨损。In this embodiment, in order to ensure that the outer cage 102 always rotates synchronously with the outer ring 109, as shown in FIG3, a notch 107 is provided on the flange 106 at one axial end of the outer cage 102. In the circumferential direction of the outer cage 102, the notches 107 are respectively located on both sides of the cross beam of the window hole 103 on the outer cage 102, so that the flange 106 section between the two notches and the corresponding cross beam of the window hole 103 jointly form a T-shaped structure 108. In the radial direction of the outer cage 102, the T-shaped structure 108 swings outward to maintain friction contact with the outer ring 109. The setting of the T-shaped structure 108 can replace the external damping card. When the overrunning clutch accelerates and decelerates rapidly, the T-shaped structure 108 overcomes the inertia force of the outer cage 102 and the wedge block 110 to ensure that the overrunning clutch is engaged and disengaged more quickly, and the wear of the wedge block 110 can also be reduced.
本实施例中，如图6所示，定义外圈109和内圈100与楔块110接触点的连线为接触线111，楔块110的质心位于接触线111的一侧，需强调的是，各楔块110的质心需位于相应接触线111的同一侧，且各弹性件均需顶压楔块110的该侧，当外圈109超越旋转时，楔块110在离心力作用下与内圈100滚道脱离接触。In this embodiment, as shown in Figure 6, the line connecting the contact points of the outer ring 109, the inner ring 100 and the wedge block 110 is defined as the contact line 111, and the center of mass of the wedge block 110 is located on one side of the contact line 111. It should be emphasized that the center of mass of each wedge block 110 must be located on the same side of the corresponding contact line 111, and each elastic member must press against the side of the wedge block 110. When the outer ring 109 rotates beyond the limit, the wedge block 110 loses contact with the raceway of the inner ring 100 under the action of centrifugal force.
本实施例提供的超越离合器的使用过程如下，内圈100与主动件传动连接，在传扭状态下，楔块110楔紧，内圈100、内保持架101、楔块110、外保持架102及外圈109相对固定装配在一起，以驱动外圈109转动，外圈109作为动力输出部输出扭矩；在超越状态下，外圈109超越旋转，楔块110在离心力作用下与内圈100滚道脱离接触，离合器
处于超越状态。与现有技术中的超越离合器比较，在本实施例提供的超越离合器中，由于弹性件112固设在内保持架101上且与楔块110一一对应，在弹性件112受到楔块110的反作用力时，弹性件112不会发生相对移动且各弹性件112之间独立受力，保证了各楔块110的受力均衡，提高了各楔块110与内圈100滚道脱开时的同步性。而且，由于弹性件112固设在内保持架101上，使得弹性件112在受到反作用力后不会发生移动，增大了弹性件112对楔块110的弹性作用力。The use process of the overrunning clutch provided in this embodiment is as follows: the inner ring 100 is connected to the driving member in a transmission manner. In the torque transmission state, the wedge 110 is wedged tightly, and the inner ring 100, the inner retainer 101, the wedge 110, the outer retainer 102 and the outer ring 109 are relatively fixedly assembled together to drive the outer ring 109 to rotate. The outer ring 109 outputs torque as a power output part; in the overrunning state, the outer ring 109 overtakes the rotation, and the wedge 110 is separated from the raceway of the inner ring 100 under the action of centrifugal force, and the clutch In the overrunning state. Compared with the overrunning clutch in the prior art, in the overrunning clutch provided in this embodiment, since the elastic member 112 is fixed on the inner retainer 101 and corresponds to the wedge block 110 one by one, when the elastic member 112 is subjected to the reaction force of the wedge block 110, the elastic member 112 will not move relatively and each elastic member 112 is independently subjected to force, which ensures the force balance of each wedge block 110 and improves the synchronization when each wedge block 110 is disengaged from the raceway of the inner ring 100. Moreover, since the elastic member 112 is fixed on the inner retainer 101, the elastic member 112 will not move after being subjected to the reaction force, which increases the elastic force of the elastic member 112 on the wedge block 110.
