Patent number: 6412887Abstract: A chain master link has first and second link parts having outer ends centered on respective substantially parallel first and second axes and coupled-together inner ends. Each inner end is formed with at least one tooth extending transversely across a plane including the two axes and having an inner face turned toward the respective axis and forming with the plane an angle of at least 90° open away from the respective axis. The teeth are engaged together with the inner faces bearing on each other so that tension pulling the parts apart along the plane pulls the teeth into engagement with each other. Each part is formed with a pocket receiving the tooth of the other part and having an outer face forming with the plane an angle open away from the respective axis and greater than the respective inner-face angle. Thus the two parts can be fitted together simply by pivoting their inner ends toward each other about the respective outer-end axes.Type: GrantFiled: October 23, 2000Date of Patent: July 2, 2002Assignee: Intertractor GmbHInventors: Michael Ketting, Friedrich Böttger

Patent number: 6135221Abstract: A drive assembly for a track-laying vehicle adapted to travel in a horizontal direction along the ground has a horizontally elongated frame having two opposite ends and upper and lower edges extending parallel to the direction between the ends, a drive wheel at one of the ends, a support fixed on the frame between the ends, and a guide on the frame extending between the fixed support and the other end along a line forming an acute angle with the direction and extending downward toward the other end. A movable support displaceable parallel to the line in the guide carries an idler wheel at the other end. A spring braced between the supports urges the idler wheel parallel to the line away from the drive wheel. A plurality of ground wheels are mounted along the lower edge between the drive and idler wheels and an endless track looped around the wheels extends parallel to the direction along the idler wheels. A drive connected to the drive wheel rotates the drive wheel and displaces the track around the wheels.Type: GrantFiled: April 19, 1999Date of Patent: October 24, 2000Assignee: Intertractor GmbHInventors: Harald Becker, Frank Tintrup, Gerhard Wagner
