以下将结合附图描述根据本申请的具体实施方式。下面的详细描述和附图用于示例性地说明本申请的原理，本申请不限于所描述的优选实施例，本申请的保护范围由权利要求书限定。The following will describe the specific implementation of the present application in conjunction with the accompanying drawings. The following detailed description and drawings are used to exemplarily illustrate the principles of the present application. The present application is not limited to the preferred embodiments described, and the protection scope of the present application is defined by the claims.
本申请实施例提供一种飞轮，尤其是一种双质量飞轮，该飞轮包括：弹簧100、初级质量、次级质量、膜片弹簧500和密封圈600。An embodiment of the present application provides a flywheel, in particular a dual-mass flywheel, which includes: a spring 100, a primary mass, a secondary mass, a diaphragm spring 500 and a sealing ring 600.
其中，初级质量包括第一壳体210和第二壳体220，第一壳体210和第二壳体220限定出用于容纳弹簧100的容置空间，第一壳体210可以用于连接到发动机的动力源，例如，发动机的曲轴。The primary mass includes a first housing 210 and a second housing 220 , which define an accommodation space for accommodating the spring 100 . The first housing 210 can be used to connect to a power source of the engine, such as a crankshaft of the engine.
弹簧100设于初级质量和次级质量之间，以衰减扭振，次级质量包括法兰410和花键毂420，花键毂420固定于法兰410，具体地，弹簧100可以设置于初级质量和法兰410之间以衰减扭振。花键毂420可输出扭矩。 例如，花键毂420可与变速箱的输入轴相连。The spring 100 is disposed between the primary mass and the secondary mass to attenuate torsional vibration. The secondary mass includes a flange 410 and a spline hub 420. The spline hub 420 is fixed to the flange 410. Specifically, the spring 100 can be disposed between the primary mass and the flange 410 to attenuate torsional vibration. The spline hub 420 can output torque. For example, the spline hub 420 can be connected to the input shaft of the gearbox.
膜片弹簧500设于法兰410和第二壳体220之间，并且是以压缩状态在飞轮的轴向上设置于法兰410和第二壳体220之间。膜片弹簧500的内周与法兰410接触，膜片弹簧500的外周与第二壳体220接触。在回复力的作用下，膜片弹簧500的内周压接在法兰410上，膜片弹簧500的外周压接在第二壳体220上，并且，膜片弹簧500的内周伸入法兰410和花键毂420之间，花键毂420和膜片弹簧500一起固定于法兰410。例如，花键毂420和膜片弹簧500一起可以通过铆接的方式固定于法兰410。The diaphragm spring 500 is disposed between the flange 410 and the second housing 220, and is disposed between the flange 410 and the second housing 220 in a compressed state in the axial direction of the flywheel. The inner periphery of the diaphragm spring 500 contacts the flange 410, and the outer periphery of the diaphragm spring 500 contacts the second housing 220. Under the action of the restoring force, the inner periphery of the diaphragm spring 500 is pressed against the flange 410, and the outer periphery of the diaphragm spring 500 is pressed against the second housing 220, and the inner periphery of the diaphragm spring 500 extends between the flange 410 and the spline hub 420, and the spline hub 420 and the diaphragm spring 500 are fixed to the flange 410 together. For example, the spline hub 420 and the diaphragm spring 500 can be fixed to the flange 410 together by riveting.
密封圈600设于膜片弹簧500和花键毂420之间。密封圈600能密封膜片弹簧500和花键毂420之间的间隙，防止油脂300从该间隙泄露。The sealing ring 600 is disposed between the diaphragm spring 500 and the spline hub 420. The sealing ring 600 can seal the gap between the diaphragm spring 500 and the spline hub 420 to prevent the grease 300 from leaking from the gap.
花键毂420和膜片弹簧500通过铆接的方式固定于法兰410，具体地，可以通过铆钉700固定于法兰410。在一个示例中，铆钉700的数量为多个，多个铆钉700在圆周方向均匀分布。该种情况下，铆钉700将花键毂420、膜片弹簧500固定于法兰410。在铆接点处，也就是，在铆钉700所在处，花键毂420和膜片弹簧500与法兰410通过铆钉700铆接在一起，在铆钉700的作用下，花键毂420、膜片弹簧500和法兰410三者之间紧密接触，没有间隙，除了铆钉700所在处，也就是在相邻铆钉700之间的空档处，膜片弹簧500的内周向一侧压接在法兰410上，膜片弹簧500的内周向另一侧和花键毂420之间可能具有间隙，在运行过程中，油脂300可以从弹簧腔(也就是弹簧100的容置空间)流到法兰410的中间部位，在一定转速的离心力作用下向外部运动，从膜片弹簧500和花键毂420的间隙泄露，本申请实施例中在膜片弹簧500和花键毂420之间设置了密封圈600，密封圈600能密封膜片弹簧500和花键毂420之间的间隙，从而防止油脂300从该间隙泄露。The spline hub 420 and the diaphragm spring 500 are fixed to the flange 410 by riveting, specifically, they can be fixed to the flange 410 by rivets 700. In one example, there are multiple rivets 700, and the multiple rivets 700 are evenly distributed in the circumferential direction. In this case, the rivets 700 fix the spline hub 420 and the diaphragm spring 500 to the flange 410. At the riveting point, that is, where the rivet 700 is located, the spline hub 420 and the diaphragm spring 500 are riveted together with the flange 410 by the rivet 700. Under the action of the rivet 700, the spline hub 420, the diaphragm spring 500 and the flange 410 are in close contact with each other without any gap, except where the rivet 700 is located, that is, in the gap between adjacent rivets 700, the inner circumference of the diaphragm spring 500 is pressed against the flange 410 on one side, and the inner circumference of the diaphragm spring 500 is pressed against the spline hub 420 on the other side. There may be a gap between them. During operation, grease 300 can flow from the spring cavity (that is, the accommodating space of the spring 100) to the middle part of the flange 410, move outward under the action of centrifugal force at a certain speed, and leak from the gap between the diaphragm spring 500 and the spline hub 420. In the embodiment of the present application, a sealing ring 600 is provided between the diaphragm spring 500 and the spline hub 420. The sealing ring 600 can seal the gap between the diaphragm spring 500 and the spline hub 420, thereby preventing grease 300 from leaking from the gap.
本申请实施例中，密封圈600为环状密封圈，可以在整个圆周方向密封膜片弹簧500和花键毂420之间的间隙，从而防止油脂300从该间隙泄露。且密封圈600的外周位于多个铆钉700所在圆周的径向之内，也就是，密封圈600的外周的直径小于多个铆钉700所在圆周的直径，设置密封圈600不影响花键毂420和膜片弹簧500通过铆接的方式固定于法兰 410。花键毂420和膜片弹簧500通过铆接的方式固定于法兰410时，膜片弹簧500和花键毂420挤压密封圈600，从而密封膜片弹簧500和花键毂420之间的间隙。In the embodiment of the present application, the sealing ring 600 is an annular sealing ring, which can seal the gap between the diaphragm spring 500 and the spline hub 420 in the entire circumferential direction, thereby preventing the grease 300 from leaking from the gap. The outer circumference of the sealing ring 600 is located within the radial direction of the circumference where the multiple rivets 700 are located, that is, the diameter of the outer circumference of the sealing ring 600 is smaller than the diameter of the circumference where the multiple rivets 700 are located. The provision of the sealing ring 600 does not affect the spline hub 420 and the diaphragm spring 500 being fixed to the flange 410 by riveting. When the spline hub 420 and the diaphragm spring 500 are fixed to the flange 410 by riveting, the diaphragm spring 500 and the spline hub 420 squeeze the sealing ring 600, thereby sealing the gap between the diaphragm spring 500 and the spline hub 420.
本申请实施例中，密封圈600为环状密封圈，可以在整个圆周方向密封膜片弹簧500和花键毂420之间的间隙，从而防止油脂300从该间隙泄露。且密封圈600的外周沿径向超出多个铆钉700所在圆周，也就是，密封圈600的外周的直径大于多个铆钉700所在圆周的直径。并且，密封圈600上设有用于避让铆钉700的避让孔。这样，设置密封圈600不会影响膜片弹簧500和花键毂420与法兰410的铆接。花键毂420和膜片弹簧500通过铆接的方式固定于法兰410时，膜片弹簧500和花键毂420挤压密封圈600，从而密封膜片弹簧500和花键毂420之间的间隙。同时，这种情况下，密封圈600的密封面积更大，密封效果更好。In the embodiment of the present application, the sealing ring 600 is an annular sealing ring, which can seal the gap between the diaphragm spring 500 and the spline hub 420 in the entire circumferential direction, thereby preventing the grease 300 from leaking from the gap. The outer circumference of the sealing ring 600 radially exceeds the circumference of the multiple rivets 700, that is, the diameter of the outer circumference of the sealing ring 600 is greater than the diameter of the circumference of the multiple rivets 700. In addition, the sealing ring 600 is provided with an escape hole for avoiding the rivets 700. In this way, the provision of the sealing ring 600 will not affect the riveting of the diaphragm spring 500 and the spline hub 420 with the flange 410. When the spline hub 420 and the diaphragm spring 500 are fixed to the flange 410 by riveting, the diaphragm spring 500 and the spline hub 420 squeeze the sealing ring 600, thereby sealing the gap between the diaphragm spring 500 and the spline hub 420. At the same time, in this case, the sealing area of the sealing ring 600 is larger and the sealing effect is better.
密封圈600为橡胶密封圈，花键毂420和膜片弹簧500通过铆接的方式固定于法兰410时，膜片弹簧500和花键毂420挤压密封圈600起到较好的密封效果。The sealing ring 600 is a rubber sealing ring. When the spline hub 420 and the diaphragm spring 500 are fixed to the flange 410 by riveting, the diaphragm spring 500 and the spline hub 420 squeeze the sealing ring 600 to achieve a good sealing effect.
可选地，密封圈600为环形薄片状的橡胶密封圈。Optionally, the sealing ring 600 is a ring-shaped thin sheet rubber sealing ring.
因此，在本申请的飞轮中，膜片弹簧500和花键毂420之间设有密封圈600，密封圈600能密封膜片弹簧500和花键毂420之间的间隙，防止油脂300从该间隙泄露。Therefore, in the flywheel of the present application, a sealing ring 600 is provided between the diaphragm spring 500 and the spline hub 420 , and the sealing ring 600 can seal the gap between the diaphragm spring 500 and the spline hub 420 to prevent the grease 300 from leaking from the gap.
