Air Drag Reduction Apparatus for Tractor-Trailers

An air drag reduction apparatus includes left and right panels and top and bottom panels for mounting to the rear doors of a tractor trailer along the top, bottom and side edges thereof. Hinges are interposed between the panels and the doors so that the panels can pivot about the hinges between an extended drag-reducing position and a collapsed position generally adjacent the rear doors. Stop devices releasably secure the panels in the extended position, and biasing devices such as tensioning springs are operative to bias the panels outwardly and rearwardly to the extended position and are further operative to permit the panels to pivot between the extended position towards and to the collapsed position upon impact and contact from an external object occurring and then return to the extended position substantially immediately upon contact ceasing thereby significantly reducing the impact damage. The apparatus also includes a ramp and wheel arrangement to facilitate opening and collapsing of the panels. The apparatus of the invention also includes an outwardly extending panel protection member projecting from the lower corner of the panel in a position for being contacted by external objects during movement of the vehicle to thereby prevent direct contact between an external object and the panel and cause the panel to move toward its collapsed position

Opening-closing mechanism with self-locking devices

The invention relates to an opening-closing mechanism with self-locking devices. The opening-closing mechanism comprises a base plate, a fairing, fairing supporting arms and power source pushing air cylinders. A rotary shaft is arranged on the base plate, one ends of the fairing supporting arms are installed on the rotary shaft in a sleeved mode, the other ends of the fairing supporting arms are connected with the fairing through fairing installation bases, the fairing is provided with closed-state limiting stop devices, open-state limiting stop devices are arranged between the fairing supporting arms and the fairing installation bases, the locking devices are arranged between the fairing supporting arms and the power source pushing air cylinders, one ends of the locking devices can move in sliding grooves of the fairing supporting arms, and the other ends of the locking devices are installed on the power source pushing air cylinders. The opening-closing mechanism is simple and reliable in structure, low in cost, high in stability and convenient to overhaul, one power source is used for achieving opening and closing the opening-closing mechanism, mechanical self locking is generated in a dead point mode, the opening-closing mechanism is locked to be kept in a set state, and an extra power source is not required to be arranged.
