Abstract

The invention provides a rolling wheel for a crawler type traveling vehicle, in which the mechanism of sealing between a bearing part and the outside and the retaining structure of a thrust bearing are simplified, rationalizing the manufacturing by simplified and facilitated machining and unnecessitated welding. This rolling wheel is constructed in such a manner that both roller pieces of a shapedivided axially are integrated by press-fitting each other at a divided part (stepped fitting part and outer fitting part).

Description

[0001] This application is a divisional application, the application number of its parent application is: 03143458.4, the application date: 2003.9.30, the name of the invention: the runner of the tracked vehicle technical field [0002] The present invention relates to a vehicle that is supported on one side of the frame and arranged on the crawler belts in order to ensure the frictional force (abbreviation: ground contact force) with the ground when a vehicle having a crawler-type running part such as a construction machine or a loading and unloading machine travels. The runner of a tracked vehicle on the non-grounded side. Background technique [0003] In the past, as a vehicle mainly used in operations on uneven ground such as construction machinery such as bulldozers and excavators, loading and unloading machinery, and agricultural machinery, a crawler-type traveling vehicle of such a structure is known. Driving wheels and floating wheels (driven wheels) are arranged at ...
