Abstract
A track roller frame assembly for a track-type vehicle includes a rugged and yet lightweight main body including a channel-shaped base, a recoil-mechanism receiving tubular casing overlyingly connected to a first end portion of the base, and a plate structure overlyingly connected to the second end portion of the base. A collar defines a bore therethrough for receiving a support member of a drive wheel preferably containing a hydraulic drive motor, and a support bracket is connected to the tubular casing for pivotally connecting the main body to the main frame of the vehicle. The weight of the superstructure and the tension forces on the drive belt that encircles the track roller frame assembly are advantageously transferred through the collar and the main body along a central vertical plane therealong and to a plurality of roller wheels centrally supported under the base. Several embodiments of the plate structure and the channel-shaped base are illustrated which collectively define a tubular beam having a particularly efficacious height 'h' to width 'b' relationship and a back-up shoulder for strengthened connection with the tubular casing.
