降噪阻尼器是用金属制造的，由一个一个降噪阻尼环和一个连接器组成，并安装在车轮上一个环形的安装槽内。为了安装这种阻尼环，需要阻尼环具有一个开口段，和一个安装在该开口端的连接器。专利申请CN200920179686.2公开了一种车轮降噪阻尼器，该阻尼器具有一个阻尼环，阻尼环的开口段安装有一个两端与阻尼环开口段两端安装孔连接的连接器，构成一个封闭环形的降噪阻尼器。但是这种阻尼器的连接器与阻尼环开口端的端部的连接方式需要使用强力粘合剂将连接器和阻尼环粘合一起，而且连接面积小，在使用时不仅影响阻尼器的连接效果、降噪效果，以及使用安全性，而且长期使用中随着阻尼环和安装槽之间的磨损，降噪效果会逐渐下降，甚至还会产生新的噪声。
发明内容
本实用新型的目的在于提供一种降噪阻尼器，能够克服现有技术 的缺陷，更好地降低车轮的行驶噪声，确保阻尼连接器与阻尼环开口段端部的有效连接，使本降噪阻尼器具有充分的开口端补偿性，以利用车轮旋转时产生的离心力提高车辆运行时的降噪效果，保证阻尼环发生磨损后仍具有良好的降噪效果，保证阻尼器的使用安全性。
在本实用新型中，该降噪阻尼器具有一个阻尼连接器和一个阻尼环。
其中，该阻尼环具有一个开口段，该开口端的段部具有一个斜面或阶梯面；该阻尼连接器具有一个管形体，该管形体的长度略小于该阻尼环开口段的长度，在该管形体的两端部各具有一个定位体，该定位体具有一个可插入该管形体端部的柱形体，和一个具有与阻尼环开口端部斜面或阶梯面相配合倾斜面或阶梯面的楔形体，该管形体内具有一个将在两端部的两个定位体向外推出的弹簧；该定位体具有一个定位孔，一个从该管形外体插入的定位销伸入该定位孔，以限定定位体的位置，当定位销被拔出后定位体被弹簧推出，与降噪阻尼环相连接。
该阻尼器安装中，该阻尼环安装到车轮上的阻尼环安装槽内时，该倾斜面或阶梯面与阻尼器连接器端面的斜面或阶梯面相配合。这样阻尼环、阻尼器连接器和车轮安装槽，在车轮轴向、径向和圆周方向相互作用，使阻尼环和阻尼器连接器被牢固地安装在车轮上。
该管形体外形可依据阻尼环整体直径制成相应弧度，以达到环的最大减噪效果，强化接器本身的定位，使车轮运行更加安全平稳。

该安装在阻尼环11安装到车轮上的阻尼环安装槽(图中未示出)内时，该倾斜面与阻尼器连接器端面的斜面相配合。这样阻尼环、阻尼器连接器和车轮安装槽，在车轮轴向、径向和圆周方向相互作用，使阻尼环和阻尼器连接器被牢固地安装在车轮上。这样阻尼环、阻尼器连接器和车轮安装槽，在车轮轴向、径向和圆周方向相互作用，使阻尼环和阻尼器连接器被牢固地安装在车轮上。
在上述各实施例中，该阻尼环11的开口段12长度的确定，依据在安装该阻尼环11时，开口段12两边的端部相互接触时，该阻尼环11直径的能够使其安装到该车轮上的阻尼环安装槽内，或者该阻尼环11开口段12的一端放入该阻尼环安装槽内后，连续将该阻尼环11推入该阻尼环安装槽。
在上述各实施例中，该管形体1可以具有与在车轮上的该阻尼环安装槽相同的周向和/或轴向曲率。
在本实用新型中，该两个定位体2中的一个可以固定安装在该管 形体1的一端，或者与该管形体1整体构成。
