Appl. No.:

11/731598

Inventors:

Steven Springer - Aurora IL, US

International Classification:

B60R 21/13

US Classification:

280756

Abstract:

A machine having a ground engaging element includes a first rigid metallic structure, a second metallic structure that is flexible with respect to the first rigid metallic structure, and a diffuser plate having a stress carrying region located between a first end and a second end. The first end has a rigid attachment to the first metallic structure, and the second end has a rigid attachment to the second metallic structure. The stress carrying region is flexible with respect to the attachments. A stress produced from a flexing of the second metallic structure relative to the first metallic structure is concentrated within the stress carrying region of the diffuser plate instead of at a weld location.

B60S 1/68

US Classification:

172508, 305107

Abstract:

An axle guard assembly of a machine protects against intrusion of wire wrap into a central cavity of a ground engaging device. The guard, which is mounted to the axle, includes a wall disposed within the cavity of the ground engaging device. A cover can be provided which includes a flange circumscribing a central portion. The central portion is disposed axially inwardly of an inboard opening to the cavity. The flange can extend radially outwardly from the central portion and axially outwardly toward the wall. The periphery of the cover can be configured such that it is larger than the opening to the cavity. In another aspect, a support vane can be provided which extends along a longitudinal axis between a first wall and a second wall and includes a planar vane surface extending substantially radially to the longitudinal axis.
