The invention discloses a plastic noise reduction fender for a rear wheel of a heavy truck, and belongs to the field of automobile parts. Cylindrical mudguard hanging holes are evenly formed in the left side, the right side and the upper portion of the interior of the U-shaped plastic mudguard, a spiral spring hook is hung on each hanging hole, and the lower portions of all the spring hooks are connected with shock pad hanging holes formed in a U-shaped rubber shock pad in the mudguard. Lantern-shaped hollow rubber buffer air bags of which the lengths are greater than 1cm are uniformly distributed below the shock pad; when the heavy truck runs in an area with poor road conditions, vibration generated by the truck body drives the fender to vibrate synchronously, the fender is made of plastics and is good in flexibility, vibration shock waves generated by the truck body are absorbed, sand brought by rotation of the wheels impacts the buffering air bag below the rubber shock pad in the fender and is buffered by the buffering air bag, and the fender is prevented from being damaged. The shock pads and the spring hooks absorb kinetic energy of gravel, so that noise is avoided, and the mudguard is prevented from vibrating.
本发明重卡后轮塑胶降噪挡泥板属于汽车配件领域,在U型的塑胶挡泥板内部的左边、右边及上方均匀设置圆柱形挡泥板挂孔、在每个挂孔的上面悬挂一个螺旋形的弹簧挂钩、所有弹簧挂钩的下方与安装在挡泥板内部U型橡胶减震垫上面的减震垫挂孔连接,减震垫的下方均匀布满了长度>1cm灯笼状的中空橡胶缓冲气囊,重卡行驶在路况较差的地区时车身产生的震动带动挡泥板同步震动、挡泥板采用了塑胶制成柔韧性较好吸收了车身产生的震动冲击波、而车轮旋转带起的沙石撞击在挡泥板内部橡胶减震垫下方的缓冲气囊上面、被缓冲气囊、减震垫以及弹簧挂钩将沙石的动能吸收不会发出噪音并且不会使挡泥板产生震动。
