摘要： Current invention corresponds to a mobility vehicle that draws its properties from a special kind of a track that can change its rigidity. The track can become rigid on its lower part corresponding to a wheel shape with large diameter or become totally flexible as usual track on upper side for practical use. When rigid, the track correspond to circular wheel and thus plays a role of a wheel in contact with the ground. The upper part of the track remains flexible and allows to use space above a the track for practical reasons. More particularly, the invention relates to a mobile system including variable flexibility track and at least two rollers around which the variable flexibility track is wrapped, wherein the rollers are adapted to change the rigidity and the curvature of the track to adapt its shape to different functionalities as being a wheel or having a part of circular wheel with different curvature or being foldable. The variable flexibility track is composed of track elements and hinges linking the track elements so as to allow rotation of the track elements with respect to each other around the hinges. Each track element bears a locking mechanism that allows a rigid positioning of the track elements with respect to the adjacent ones at various angles. The rollers are in contact with the variable flexibility track and can contain mechanisms to lock a track elements thus changing track rigidity and/or mechanisms to change track curvature. The tracks also play a role of shock absorbers and bear mechanisms to perform turning of the vehicle by applying different speed and/or curvature to the tracks.

摘要： A track shoe deflection limiter is fastened to each outboard edge portion of each track shoe of an endless track assembly. Each deflection limiter has a first arm portion and a second arm portion. The first arm portion of each limiter overlaps a portion of the adjacent track shoe and is in close proximity to the second arm portion of the limiter which is fastened on the adjacent track shoe. When wide track shoes are used on a track-type vehicle, the outer end portions of the shoes are often twisted and deflected, relative to adjacent shoes, by an external force, such as a rock which the track shoe passes over. The shoe deflection is transferred to the track joints, including the track links, bushings, pins, and seals, which results in accelerated wear of these track assembly components. The track shoe deflection limiter of the present invention utilizes contact between adjacent deflection limiters to share externally imposed forces between adjacent track shoes, thereby limiting the deflection of individual track shoes.

摘要： A resilient element is associated with an overlapping portion of a crawler tractor track shoe so that the adjacent shoe initially contacts the resilient element during back-bend flexure prior to the grouser of this same adjacent shoe contacting the overlap portion of the first shoe. The resilient element, by reducing impact velocity, serves to lessen operating noise and prolong shoe life.

摘要： A track pad for the support and propulsion of track propelled vehicles (e.g. asphalt paving machines) comprising a support plate having a longitudinal axis which is greater than its transverse axis, a coating of heavy duty polymer (e.g. a thermoplastic urethane elastomer resin) which substantially encapsulates the support plate, and a means for securing the track pad to the track. The support plate is provided with suitable openings to accommodate the positioning therethrough of a securing means (e.g. flat head carriage bolts), said securing means for removably attaching the track pad to the track. The track pad of this invention is manufactured by pre-assembly of the securing means and the support plate whereafter the pad material is injection molded such as to substantially encapsulate the support plate.
