Abstract: A method of operating a dual bidirectional input to single bidirectional output transmission is disclosed. The method includes providing said transmission. The method includes activating a computer controller capable of receiving torque data signals from a first bidirectional torque input, a second bidirectional torque input, and a single bidirectional torque output. The method includes determining torque input from said first and second bidirectional torque input, and determining whether to transmit torque to said single bidirectional torque output. In cases where it is so determined, the method involves transmitting torque to said single bidirectional torque output.

Abstract: An endless vehicle track includes a body having an outer surface and an inner surface. The outer surface includes a carcass and a series of ground engaging profiles longitudinally spaced along the outer surface. The inner surface includes a wheel path and a series of longitudinally spaced guide-drive lugs. One or more of the series of ground engaging profiles, the series of longitudinally spaced guide-drive lugs, the carcass and the wheel path comprise a urethane material.

Abstract: A segmented rubber track having a plurality of rubber track segments is disclosed. The rubber track segments include first and second ends that include rubber bushings through which a connecting pin is inserted. The connecting pin connects one rubber track segment to another rubber track segment.

Abstract: The present invention relate to a caterpillar track, in particular a rubber caterpillar track, with a track body ad with at least one outer profiling element, preferable with a plurality of outer profiling elements, which are directed outwardly away from the track body. The caterpillar track is characterized in that the outer profiling element has an outwardly directed grouser body and a grouser root, which connects the grouser body to the track body, wherein the outer profiling element has, at least in some sections, a marking which can make the boundary between the grouser body and the grouser root visually and haptically identifiable.

Abstract: A dual bidirectional input to single bidirectional output transmission (or gear box) comprising of unique gear ratios between each of the bidirectional inputs and the single, or common, bidirectional output is disclosed. The gear box has a gear train design with two bidirectional inputs and one (or common) bidirectional output. The device is configured to enable torque to be transmitted through either one or both of the bidirectional inputs to the bidirectional output. The gear train may be a constant mesh system which eliminates sliding splines, dog clutches or synchronizers to switch between operational modes. A locking feature/component/element allows the power or torque to be transmitted from a first bidirectional input to the common bidirectional output using a second bidirectional input as a fixed rotation reference. Similarly power or torque from the second bidirectional input to the common bidirectional output may use the first bidirectional input as a fixed rotation reference.
