Abstract: A mobile construction vehicle has a pair of parallel first and second track assemblies. Each track assembly has a continuous drive belt with a plurality of teeth thereon, driven by a drive wheel with a plurality of lugs thereon. The drive belt teeth and drive wheel lugs have substantially identical matching profiles, to provide drive belt retention for preventing the teeth from disengaging from the drive wheel lugs, during a turning maneuver of the vehicle.

Abstract: A material flow modifying device is for a screed assembly of a paving machine. The screed assembly has a main screed with a central axis extending in a direction of intended travel of the paving machine and two screed extensions movably mounted to the main screed. The flow modifying device includes a deflector member connected with the screed extension and having a flow surface facing toward the central axis of the main screed. The flow surface is contactable with paving material on a base surface and is configured to displace the material toward the central axis when the paving machine moves in the intended travel direction. The deflector member has a first end disposed adjacent to the inner vertical surface of the screed extension and a second, free end disposed proximal to the front vertical surface of the main screed, such that the second end moves laterally along the main screed during movement of the screed extension.

Abstract: A wear compensating device for a slope adjusting assembly for an extendable screed section of a paver includes a saddle support assembly on the screed, for supporting an extendable screed section, a saddle assembly on the saddle support assembly for carrying extendable guide members to support the extendable screed section, and an adjustable cam follower positioned between the saddle assembly and the saddle support assembly for providing rolling contact between the saddle assembly and the saddle support assembly, to maintain alignment between the saddle support assembly and the saddle assembly.
