    Abstract: A noise attenuating system for the tracks of a track-laying vehicle. A plurality of noise attenuating devices are disposed about the track chain of a track-laying vehicle, one device mounted upon each track shoe. Each device is comprised of a preloaded spring means in the form of a block or pad of elastomeric material and each device is mounted upon the inner circumferential portion of an individual track shoe. A wear plate means is included for directly engaging the radially outermost portions of the teeth of the driving sprocket of the track-laying vehicle. The devices are disposed so that the outermost edges of the sprocket teeth engage the wear plates prior to engagement of the track bushings with the sprocket notches and are also disposed so that metal-on-metal contact between the leading and trailing edges of each respective link shoe is preceeded by contact between each respective leading edge and the elastomeric material from which the spring means are composed.

    Abstract: A notched drive sprocket for track-type vehicles having improved noise suppression characteristics is provided. The drive sprocket includes means for absorbing impact energy of the track bushings as they engage the drive sprocket comprising elastomeric inserts disposed within the root area of the sprocket teeth. The impact absorption means further automatically eject dirt or other materials from the root area which have been compacted therein by the bushings.

    Abstract: An endless track assembly for use with a track-type vehicle having a notched drive sprocket is provided with link elements having a resilient mid-pitch impact lug located midway between the track link bushings. The resilient mid-pitch lug reduces track noise and wear due to metal-to-metal impact of the track against the sprocket and idler by having a topmost portion of greater height than adjacent bushings whereby initial contact is made by the lug so that impact energy is thereby absorbed prior to engagement of the track bushings.

    Abstract translation: 与具有缺口驱动链轮的履带式车辆一起使用的环形轨道组件设置有连接元件,该连杆元件具有位于轨道连杆衬套之间的中间的弹性中间间距冲击突起。 由于金属对金属对链轮和惰轮的冲击,相对于相邻衬套的最高部分具有较大的高度,因此弹性中间间距突起减小了轨道噪音和磨损,从而通过凸耳进行初始接触,从而使冲击能量 从而在轨道衬套的接合之前被吸收。
