Abstract

The present invention relates to a connecting-rod type rubber crawler. A mandrel rod comprising a left wing, a right wing and a central part is, perpendicularly and at an approximately same space, embedded into the rubber crawler along the length direction with respect to the circumferencial direction of a rubber crawler main body. A protuberance is provided on the rubber crawler at the side on which the rubber crawler is brought into contact with the earth. The two sides of the upper central part of the mandrel rod is provided with crawler couplers and the front and the rear crawler couplers are connected with each other to a bend over state, thus to form a track by a pair of continuous crawler couplers. The invention is characterized in that a rubber crawler main body is made to continue to itself along its circumferential direction and on the outsides of stone guards projecting from the vehicle frame, curving portion is formed between adjacent mandrel rod wings toward their inner peripheries, and the width L1 of mandrel rod wings embedded into the connecting-rod type rubber crawler main body is shorter than the width L2 of the two outside parts of the installation position of the crawler couplers formed on the central part of the mandrel rod(L1 B62D 55 / 24 20 10 4 2001 / 7 / 30 1358647 2002 / 7 / 17 1125742 2003 / 10 / 29 2003 / 10 / 29 Fukuyama Gomu Kogyo K.K.

Description

[0001] This case is a divisional application of the invention patent application with the application number 96102596.4, the application date is January 31, 1996, and the title is "connecting rod type rubber track and its mandrel". technical field

[0002] The invention relates to a connecting rod type rubber crawler mounted on the bottom of walking construction machinery, civil engineering machinery and the like. Background technique

[0003] In the past, steel crawlers were used without exception in walking construction machinery, however, rubber crawlers have been increasingly used in recent years. In the steel track, the upper surface of the track connecting rod becomes a continuous runner track, so that the vibration is small when walking, and there is no stretching in the circumferential direction and the width direction, and there is no lateral deviation, so the track is less likely to fall off. In addition, it also has Due to the high mechanical connection strength b...
