Monitoring system for automatically estimating and monitoring the correct alignment of the tracks, particularly of the track chains, and relevant method
A monitoring system is disclosed for automatically estimating and monitoring the alignment of tracks of a track-type vehicle. The track-type vehicle includes an undercarriage and two tracks. Each track includes a chain with a plurality of chain links and articulated joints. The monitoring system includes at least one undercarriage sensor fixable on the undercarriage, at least one chain sensor fixable on the chain of each of the two tracks, and a processor configured to combine the detections of the sensors to determine the alignment direction of the tracks and to compare the determined direction with a reference alignment direction.
A track link is configured to be fixed to a track shoe with bolts and nuts. The track link comprises: two connecting holes which are spaced from each other by a predetermined distance in a link pitch direction and are configured to receive a link connection member respectively; a first through hole which extends orthogonal to the connecting holes and is configured to receive one of the bolts; a first surface in which the first through hole opens and on which one of the nuts is to be placed; a second through hole which extends orthogonal to the connecting hole and is configured to receive another bolt; a second surface in which the second through hole opens and on which another nut is to be placed; first projecting portions as a pair, each projecting from the first surface and facing each other in the link pitch direction across the first through hole; and second projecting portions as a pair, each projecting from the second surface and facing each other in the link pitch direction across the second through hole. The first projecting portions are spaced apart from each other by a first distance through which one of the first projecting portions engages with the nut that is to be placed between the first projecting portions but the other of the first projecting portions does not. The second projecting portions are spaced apart from each other by a second distance through which one of the second projecting portions engages with the nut that is to be placed between the second projecting portions but the other of the second projecting portions does not, or both of the second projecting portions engage with the nut.
A heavy duty vehicle (2) according to the invention comprises A) a crawler track (1, 1') on which the rest of the vehicle can roll so as to move; B) at least one sensor (100, 100', 100", 100"') configured for detecting a physical quantity of the crawler track (1) itself, of the heavy duty vehicle (2) or of the environment contained or surrounding the crawler track (1) or the heavy duty vehicle; C) a power supply unit (102) configured for supplying said sensor with electric power. The power supply unit (102) comprises a rectenna (1020) configured for receiving electromagnetic power from an external electromagnetic source (104) and for supplying said sensor (100, 100', 100", 100"') with at least part of said electromagnetic power. The invention also relates to a crawler track, shoe, track link, undercarriage assembly for such a vehicle.
An undercarriage assembly for a track-type vehicle is described. The assembly comprises at least one closed-ring rubber belt, internally provided with a continuous insert made of a plurality of metal elements embedded in the rubber mass that constitutes the rubber belt. The metal elements are positioned at a fixed and predetermined distance apart from one another, which determines the pitch of the rubber belt. The rubber belt further encloses therein one or more reinforcing elements, each consisting of a metal wire bundle oriented according to an axis substantially parallel to the longitudinal development central axis of the rubber belt. The assembly also comprises a plurality of rolling elements of each rubber belt, consisting of at least one drive sprocket, configured to mesh with the metal elements of the continuous insert and to rotationally move the respective rubber belt, of at least one idler wheel and of a plurality of rollers. Each drive sprocket consists of a gear integral with at least one disk arranged on a plane parallel to the development plane of the gear. An annular groove is interposed between the gear and each disk and each disk is provided with a smooth circumferential surface that engages with a predefined portion of the inner surface of the rubber belt, so as to absorb one part of the contacting forces that are generated between the rubber belt and the entire plurality of rolling elements of the rubber belt.
