STRUCTURE FOR IMPROVING A LEAF SPRING NOISE OF A VEHICLE USING A SILENCER INCLUDING A NOISE REMOVING HOLE AND A NOISE REMOVING INCISED PORTION

摘要

PURPOSE: A structure for improving the leaf spring noise of a vehicle is provided to effectively reduce the frictional noise generated between leaf springs by adopting a silencer having noise reducing holes and a noise removing incised portion and to easily realize the leaf spring noise reduction structure. CONSTITUTION: A leaf spring(p) is inserted to a central channel(9) of a silencer(1). Other leaf springs are installed at the upper and lower portions of the central channel. A fixing unit is placed between the silencer and the leaf springs inserted to the central channel. The fixing unit consists of a fixing protrusion(3) protruded toward the central channel from the upper portion of the silencer and a fixing recess(5) formed in the leaf spring inserted to the central channel. Noise reducing holes(11) are formed upward in the central channel of the silencer and a noise removing incised portion(13) formed in the lower portion of the central channel.
