    • An undercarriage for a construction machine having a support frame and at least one carrier roller positioned on an upper surface of the support frame for providing upper guidance to the chain or band. The carrier roller is constructed from two bearing pins coaxially arrange on opposite sides of the roller, and includes a plurality of axially parallel driving pins arrange equidistantly along a coaxial circumferential circle on one side face of the roller. The driving cams on the chain engage between two adjacent driving pins thereby eliminating relative movement between the chain or band and the carrier roller.
    • 一种用于建筑机械的底架,具有支撑框架和至少一个承载辊,所述至少一个承载辊定位在所述支撑框架的上表面上,用于向所述链条或带施加上部引导。 承载辊由同轴布置在辊的相对侧上的两个轴承销构成,并且包括沿辊的一个侧面上的同轴圆周周向等距离布置的多个轴向平行的驱动销。 链条上的驱动凸轮接合在两个相邻的驱动销之间,从而消除链条或带与承载辊之间的相对运动。
