Description

摩托车排气消声器
技术领域
本发明涉及一种摩托车配件，具体涉及一种摩托车排气消声器。
背景技术
为减少摩托车发动机排气的噪声污染，各型摩托车都设置有消声器，消声器是一种允许气流通过而衰减噪声的装置，是摩托车的一个重要部件。传统的摩托车消声器一般都是在摩托车的排气筒中安装几级金属挡板，采用金属挡板将排气筒的腔体隔断，使其形成几个气室，摩托车发动机的排气气流经过各个气室时，通过气流在各气室的膨胀或回旋，从而达到降低排气噪声的目的，但是这种结构的消声器在对发动机排出的高压废气、烟体等进行逐级减缓的同时，其所产生的反冲阻力在启动、变速、变档过程中影响动力的平稳，发动机功率损耗大。
为解决上述问题，中国发明专利201220017684.2公开了一种摩托车排气消声器，包括排气筒主体，所述的排气筒主体的腔体中固设有一直通气道，该直通气道包括前消声管、后消声管和出气管，后消声管的两端分别与前消声管和出气管的一端连接，前消声管和出气管的另一端分别与排气筒主体的前端和后端连接，前消声管和后消声管上分别设有密集气孔的气孔通道，后消声管上气孔通道的气孔密度大于前消声管上气孔通道的气孔密度。前述后消声道外表面上可按需套设钢丝网，在钢丝网的外表面与排气筒主体内壁之间设置耐热吸音棉。本发明结构简单，工作可靠，消声效果好，降低了对发动机功耗的影响。但是流经该排气筒主体的废气未被有效的净化处理，排放后会造成环境污染。
另外，消声器使用一段时间后，在尾罩内会有积水，容易锈蚀消声器，致其寿命缩短。
发明内容
本发明目的是提供一种废气净化处理彻底、排放无污染、消声器使用寿命长的摩托车排气消声器。
为达到上述目的，本发明采用的技术方案是：一种摩托车排气消声器，

其中，所述消声器筒体的后端设有排水孔。
上述的摩托车排气消声器还包括沿消声器长度方向延伸的护罩，所述护罩的前端与排气管固定连接，中部与消声器筒体固定连接，后端与尾罩卡接。
由于上述技术方案运用，本发明与现有技术相比具有的优点是：
1.本发明在直通气道的外侧包覆有钢丝网，并在钢丝网和消声器筒体内壁之间设置消音棉，消音效果好，并以此为基础在排气管上设置催化转化器，净化流经排气筒主体的废气，保证排放气体为环保气体。
