The embodiment of the invention discloses a bridge acoustic package and an integrated forming processing method. A bridge acoustic package, a motor part, a speed reducer part and an electric control unit part are integrally designed, and sequentially comprise a first black flame-retardant non-woven fabric, a V0-level thermoplastic elastomer or a felt material mixed with polyester and pre-oxidized polyester fibers, LDPUR semi-perforated light foam and a second black flame-retardant non-woven fabric from top to bottom. The bridge acoustic package can effectively solve the sound insulation problem of the bridge.

    本发明实施例公开了一种电桥声学包裹及一体成型加工方法。本发明的电桥声学包裹,所述电动机部分、所述减速器部分和所述电控单元部分为一体式设计,且从上往下依次为:第一黑色阻燃无纺布、V0级的热塑性弹性体或混合了聚酯及预氧化聚酯纤维的毡材、LDPUR半开孔型轻质发泡和第二黑色阻燃无纺布。本发明的电桥声学包裹可以有效解决电桥的隔音问题。
