Abstract
Abstract A track-type vehicle having a track made up of links with contact surfaces of high wear-resistant material engaging with the track rollers as the track is driven on the vehicle. The high wear-resistant material may be a composite alloy metallurgically bonded into a groove in the contact surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
In a vehicle having a track made up of a plurality of interconnected links, roller means on said vehicle over which said links of said track pass, a contact surface on each of said links engaging with said roller means as said links pass said roller means, said contact surface having a bar of hard wear-resistant material bonded in a groove formed in said link whereby said contact surface will resist wearing away due to said contact with said roller means.
Claim 2
Dependent Claim
81 words
In a vehicle having a track made up of a plurality of interconnected links, roller means on said vehicle over which said links of said track pass, a contact surface on each of said links engaging with said roller means as said links pass said roller means, said contact surface having a bar of hard wear-resistant material bonded in a groove formed in said link whereby said contact surface will resist wearing away due to said contact with said roller means.
Claim 3
Dependent Claim
