Document Type and Number:
WIPO Patent Application WO/2015/178524
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a multi terrain loader undercarriage capable of efficiently transmitting power and preventing the rubber track from being damaged by stress concentration. The undercarriage according to the present invention comprises: a rubber track (40) having driving lugs (42) continuously formed on the inner surface thereof at a predetermined interval; and a driving sprocket (20), which is rotated by a driving force from the engine, which has a plurality of roll sleeves (22) that engage between the driving lugs, and which is installed on the rear end of the interior of the rubber track. In addition, an idler (52) is installed on the front end of the interior of the rubber track, and multiple track rollers (54) are installed between the driving sprocket and the idler. The rubber track contacts the ground between parts of contact with the idler and the driving sprocket, and the driving sprocket contacts the rubber track before the rubber track is spaced from the bottom surface. The driving sprocket is formed to have a diameter larger than those of the idler and the track rollers, and the driving sprocket is spaced from the rubber track at the upper end corresponding to a part at which the rubber track starts to make a contact. It is also possible to always maintain the tension of rubber track in an optimum state using first and second tension adjusting means.
