Traveling Device and Working Machine

摘要

A travelling frame of a travelling device positioned between a center frame and a travelling motor attachment portion includes an upper plate extended toward the center side of the vehicle to form an extended portion. A long hole into which travelling motor hydraulic piping is inserted is formed in the upper plate along the extended portion. The travelling motor hydraulic piping extends from a lead-out hole opened in an end plate of the center frame, through the long hole of the upper plate and a tong hole opened in an end plate, and inserted into the travelling motor attachment portion.

主权项

1. A traveling device comprising:
a center frame positioned at a vehicle center; a travel frame including an upper surface plate integrally provided on a lower side of the center frame; a crawler belt attached along the travel frame; a travel motor attachment unit integrally provided on one end side of the travel frame; a crawler belt driving unit that drives the crawler belt to rotate, by using a hydraulic travel motor attached to the travel motor attachment unit; and a travel motor hydraulic pipe arranged from the center frame to the hydraulic travel motor of the crawler belt driving unit through the travel frame, the traveling device further comprising: an expanded portion formed by expanding the upper surface plate of the travel frame positioned between the center frame and the travel motor attachment unit, toward the vehicle center side; and a long hole which is formed in the upper surface plate of the travel frame along the expanded portion and through which the travel motor hydraulic pipe is inserted.
