本申请要求常州中车铁马科技实业有限公司,中车戚墅堰机车车辆工艺研究所有限公司于2017年12月29日提交的、发明名称为“铁道车辆用轴装制动盘装置”的、中国专利申请号“201711477310.2”的优先权。
技术领域
本发明涉及铁道车辆技术领域，特别是涉及一种铁道车辆用轴装制动盘装置。
背景技术
轴装制动盘已经广泛运用于城轨、地铁、客车以及动车组拖车车辆中，主要可以弥补车辆电制动力或者动力车制动力的不足。轴装制动盘装置一般会包含摩擦用的盘体、与轴连接传递制动扭矩的盘毂、隔圈、起紧固作用的螺栓、螺母等零件。
相关方案中的轴装制动盘采用螺栓空套穿过盘体、盘毂以及隔圈的连接方式，同时另外增加了铝丝作为组装定心元件，此种轴装制动盘结构简单，零件设计容易，但此种结构由于采用内置定心环结构，组装难度增加，同时螺栓在孔中空套着，一旦遇到螺栓松动，制动力将直接由紧固件承受，紧固件出现断裂风险较大。
另外，为了使螺栓的连接更加牢固，在隔圈外侧以及法兰外侧设置垫片。上述实用新型在长时间使用后，垫片会出现内凹变形，从而导致出现松动的风险。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。
为此，本发明的一个目的在于提出一种铁道车辆用轴装制动盘装置，该铁道车辆用轴装制动盘装置在组装时具有自定心功能，且可以较好防止松动。
根据本发明的铁道车辆用轴装制动盘装置，包括：盘体、盘毂、隔圈、弹性套筒以及紧固件，所述盘体内壁上设有盘体连接爪，每个所述盘体连接爪上设有连接爪螺栓孔；所述盘毂前侧的外圆周上设有法兰，所述法兰上设有与连接爪螺栓孔对应的第一紧固件孔；所述隔圈与所述法兰间隔开以夹设所述盘体连接爪，所述隔圈上设有与所述连接爪螺栓孔和所述第一紧固件孔一一对应的第二紧固件孔；所述弹性套筒设置在所述连接爪螺栓孔中；所述紧固件穿过所述第一紧固件孔、弹性套筒的内孔和所述第二紧固件孔以将所述盘体固定在所述盘毂上。
由此，根据本发明的铁道车辆用轴装制动盘装置，通过设置在紧固件的轴向上，位于隔圈与盘毂的法兰之间的弹性套筒，在紧固件的径向上，位于盘体与紧固件之间、位于盘毂与坚固件之间的弹性套筒，不仅在制动盘的制动过程中，可以吸收剪切应力，以降低紧固件出现断裂的风险，提高制动盘的使用寿命，而且可以通过弹性套筒所具有的弹性，在制动盘的制动过程中，为盘体提供部分缓冲，以降低制动盘制动过程中的噪声。
本发明的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。
附图说明

图2是图1沿A-A方向的剖视图；和
图3是图1中圈示B的局部放大图。
具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
如图1和图2所示，根据本发明的铁道车辆用轴装制动盘装置，包括：盘体1、盘毂2、隔圈3、弹性套筒4以及紧固件5，盘体1的内壁上设有盘体连接爪1-1，每个盘体连接爪1-1上设有连接爪螺栓孔1-2；盘毂2前侧的外圆周上设有法兰2-2，法兰2-2上设有与连接爪螺栓孔1-2对应的第一紧固件孔；隔圈3与法兰2-2间隔开以夹设盘体连接爪1-1，隔圈3上设有与连接爪螺栓孔1-2和第一紧固件孔一一对应的第二紧固件孔；弹性套筒4设置在连接爪螺栓孔1-2中；紧固件5穿过第一紧固件孔、弹性套筒4的内孔4-1和第二紧固件孔以将盘体1固定在盘毂2上。
根据本发明的铁道车辆用轴装制动盘装置，通过设置在紧固件5的轴向上，位于隔圈3与盘毂2的法兰2-2之间的弹性套筒4，在紧固件5的径向上，位于盘体1与紧固件5之间、位于盘毂2与坚固件之间的弹性套筒4，不仅在制动盘的制动过程中，可以吸收剪切应力，以降低紧固件5出现断裂的风险，提高制动盘的使用寿命，而且可以通过弹性套筒4所具有的弹性，在制动盘的制动过程中，为盘体1提供部分缓冲，以降低制动盘制动过程中的噪声。
如图2所示，第一紧固件孔为由法兰2-2小径孔和法兰2-2大径孔组成的法兰阶梯孔2-3，第二紧固件孔由隔圈3小径孔和隔圈3大径孔组成的隔圈阶梯孔3-1，弹性套筒4的 前端插入对应的法兰2-2大径孔中，弹性套筒4的后端插入对应的隔圈3大径孔中。也就是说，法兰2-2在与弹性套筒4配合的区域、隔圈3在与弹性套筒4配合的区域上均形成有变径结构的阶梯孔，通过该阶梯孔的设置，可以避免弹性套筒4在轴向上的窜动，提高弹性套筒4对紧固件5的剪切力的分散效果。
在图2所示的具体的实施例中，弹性套筒4的内孔4-1直径均小于法兰2-2小径孔的直径和隔圈3小径孔的直径。这样，使弹性套筒4可以更加方便的安装到隔圈3、盘毂2与盘体1所限定的空间内，提高装配效率。
可以理解的是，弹性套筒4与法兰2-2大径孔、连接爪螺栓孔1-2和隔圈3大径孔均为过盈配合。由此，可以进一步地提高弹性套筒4与法兰2-2、弹性套筒4与隔圈3的连接稳定性更高，可以有效地提高制动盘的结构强度。
其中，法兰2-2小径孔的直径D2或隔圈3小径孔的直径D3与弹性套筒4的内孔4-1直径D1的差值为0.5mm～1.5mm。也就是说，法兰2-2小径孔、隔圈3小径孔的直径与弹性套筒4的直径差值均不超过1.5mm且不低于0.5mm，在方便弹性套筒4的安装的同时，可以避免弹性套筒4与盘体1之间、弹性套筒4与盘毂2之间的径向间隙过大。
参见图2，弹性套筒4的两端各设有倒角4-2。由此，可以通过倒角4-2对弹性套筒4的安装提供导向，进而进一步地提高弹性套筒4的安装效率。
其中，由法兰2-2大径孔、连接爪螺栓孔1-2和所述隔圈3大径孔构成组合孔，弹性套筒4的长度小于组合孔的长度。这样，可以避免装配过程中，弹性套筒4长度过长，导致隔圈3与法兰2-2之间无法完全紧固，使制动盘的结构更加合理，以进一步地提高制动盘的结构稳定性。
需要说明的是，组合孔的长度与弹性套筒4的差值为0.5mm～2mm。由此，可以避免弹性套筒4出现轴向的窜动，降低制动盘工作过程中的工作噪声。
如图1所示，盘体连接爪1-1为多个，且多个盘体连接爪1-1中的至少部分的连接爪螺栓孔1-2中设有弹性套筒4。也就是说，在一些实施例中，每一个盘体连接爪1-1的连接爪螺栓孔1-2中均设置有弹性套筒4，在另一些实施例中，多个盘体连接爪1-1的连接爪螺栓孔1-2中，只有一部分设置有弹性套筒4。
在图2所示的具体的实施例中，紧固件5的尾部伸出隔圈3，紧固件5的尾部上连接有碟形弹簧片且由自锁螺母7固定。也就是说，紧固件5依次穿过法兰2-2、盘体连接爪1-1、隔圈3以及蝶形弹簧片6后与自锁螺母7螺纹紧固。
这样，一方面，可以通过自锁螺母7的自锁效应，避免紧固件5松动，另一方面，当隔圈3与自锁螺母7相对的表面被磨损出现凹陷时，蝶形弹簧片6的弹性形变弥补该凹陷，也可以有效地避免紧固件5松动。
实施例1
见图1至图3，本实施例包括盘体1、盘毂2、隔圈3、弹性套筒4、螺栓5、碟形弹簧片6和自锁螺母7。盘毂2前侧的外圆周上设有法兰2-2，盘体内壁上均布有盘体连接爪1-1，盘体连接爪1-1被法兰2-2和隔圈3所夹持，盘体连接爪1-1的个数为偶数或者3的倍数(包括3个)。
每个盘体连接爪1-1上设有连接爪螺栓孔1-2，法兰2-2上设有与连接爪螺栓孔1-2一一对应的第一紧固件孔，隔圈3上设有与连接爪螺栓孔1-2一一对应的第二紧固件孔。法兰上的第一紧固件孔由外侧的法兰小径孔2-3-1和内侧的法兰大径孔2-3-2组成的法兰阶梯孔2-3，隔圈3上的第二紧固件孔由外侧的隔圈小径孔3-1-1和内侧的隔圈大径孔3-1-2组成的隔圈阶梯孔3-1。
所有连接爪螺栓孔1-2中，至少有2个连接爪螺栓孔1-2中设有弹性套筒4，弹性套筒4由弹簧钢制成。弹性套筒4的前端插入法兰大径孔2-3-2中，弹性套筒4的后端插入隔圈大径孔3-1-2中，弹性套筒4的两端各设有倒角4-2，方便弹性套筒4两端能分别插入相应的法兰大径孔2-3-2和隔圈大径孔3-1-2中，为组装提供便利。弹性套筒4与法兰大径孔2-3-2、连接爪螺栓孔1-2和隔圈大径孔3-1-2均为过盈配合，弹性套筒4的内孔直径D1均小于法兰小径孔2-3-1的直径D2和隔圈小径孔3-1-1的直径D3，D2与D1的差值在0.5～1.5mm之间。由法兰大径孔2-3-2、连接爪螺栓孔1-2和隔圈大径孔3-1-2组成组合孔，弹性套筒4的长度H1小于组合孔的长度H2，H2与H1的差值在0.5～2mm之间。螺栓5通过法兰阶梯孔2-3、连接爪螺栓孔1-2和隔圈阶梯孔3-1，尾部穿出隔圈3，尾部上连接有所述2片碟形弹簧片6和所述自锁螺母7。由于采用2片碟形弹簧片6和自锁螺母，在连接面出现磨损后，通过碟形弹簧片6的变形量依旧能保持紧固件可靠连接，使制动盘装置具有较可靠的防松性能。
紧固件5为六角螺栓，法兰阶梯孔2-3的前端设有六角沉孔2-4，紧固件5的头部5-1的局部置于六角沉孔2-4中，可以有效地防止紧固件5转动，进一步增强了紧固件的防松能力。
