The invention discloses a tension maintaining unit of a crawler device and a crawler device provided with the same. A tension maintaining unit of a crawler device according to the present invention comprises: a rotation direction selecting section having a first one-way bearing section having a first one-way bearing connected to a first rotating member of a crawler body, and a second one-way bearing section having a second one-way bearing connected to a second rotating member of the crawler body; the second one-way bearing part is provided with a second one-way bearing connected with a second rotating component; and a drive unit that transmits power to the first one-way bearing unit and the second one-way bearing unit, that is driven by the power of the second one-way bearing unit when the crawler main body moves in the forward direction, and that causes the first one-way bearing unit to rotate freely so as to prevent the tension of the crawler member provided on the crawler main body from loosening, and that causes the second one-way bearing unit to rotate freely so as to prevent the tension from loosening when the crawler main body moves in the backward direction. And a second one-way bearing that is driven by the power of the first one-way bearing and rotates freely to prevent the tension of the crawler member from becoming loose, and a rotation direction selection unit that is coupled to a drive unit output shaft provided on the drive unit to receive the power.

    本发明公开履带装置的张力维持单元及具备它的履带装置。本发明履带装置的张力维持单元的特征在于,包括:旋转方向选择部,具有第一单向轴承部及第二单向轴承部,第一单向轴承部具有与履带主体的第一旋转部件连接的第一单向轴承,第二单向轴承部具有与第二旋转部件连接的第二单向轴承;及驱动部,向第一单向轴承部和第二单向轴承部传递动力,在履带主体向前进方向移动时,利用第二单向轴承的动力进行驱动,且第一单向轴承自由旋转以防止设置在履带主体上的履带部件的张力变松弛,在履带主体向后退方向移动时,利用第一单向轴承的动力进行驱动,且第二单向轴承自由旋转以防止履带部件的张力变松弛,旋转方向选择部与设置在驱动部上的驱动部输出轴结合以接收动力。
