A track driven vehicle comprises a structural member underneath the vehicle. The structural member includes a plurality of structural member apertures for receiving fasteners inserted therethrough. The vehicle also includes a first track carrier and a first mounting strut attached to the first track carrier. The first mounting strut, which attaches the first track carrier to the structural member, includes a plurality of mounting strut apertures which, when aligned with the structural member apertures, receive the fasteners inserted therethrough. One of the first mounting strut and the structural member includes a fixedly attached dowel pin, and the other of the first mounting strut and the structural member includes a pin receiving aperture. When attaching the first track carrier to the structural member using the first mounting strut, the dowel pin extends into the pin receiving aperture to prevent cross-shearing between the structural member and the first mounting strut. This reduces camber between the structural member and the track carrier and allows fewer fasteners to be used to attach the first track carrier to the structural member.
Description
Background technique [0001] Loaders and other track-driven vehicles typically have a track loader undercarriage (track carrier or track frame) that is physically coupled to a structural member such as the vehicle's transmission tub. A number of fasteners are typically used to mount the track undercarriage to the transmission. If these fasteners are not turned sufficiently, or if the joint slips, the track frame is slipping, causing the track frame to warp. As the weight of a track-driven vehicle increases, the number of bolts required to hold the track brackets typically also increases, increasing cost and assembly time. [0002] The above discussion is provided for general background information only and is not intended to be used as an aid in determining the scope of claimed subject matter. Contents of the invention [0003] The disclosed embodiments incorporate a dowel pin connection mechanism and bolts or other fasteners to connect the track frame of a tracked vehicle ...
