A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.

A door assembly system for public transportation that includes: a public transportation vehicle having an outer shell and an inner passenger compartment; at least one door having an outer surface, an inner surface, a top, a bottom and two sides, wherein the door slides to open so that passengers can enter or exit the inner passenger compartment; a C-shaped rail, wherein the rail is coupled to the outer shell of the vehicle; and a coupling component that is coupled to the inner surface of the door and is designed to mate with or engage with the C-shaped rail in a slideable manner. A method of securely opening a door on public transportation that includes: providing a train, bus or public transportation vehicle having an outer shell and an inner passenger compartment; providing at least one door having an outer surface, an inner surface, a top, a bottom and two sides, wherein the door slides to open so that passengers can enter or exit the inner passenger compartment; providing a door assembly kit, the kit comprising a C-shaped rail and a coupling component; installing the C-shaped rail to the outer shell of the vehicle; installing the coupling component to the inner surface of the door, opening the door; and mating or engaging the coupling component with the C-shaped rail in a slideable manner.

An autonomous can include one or more configurable passenger seats to accommodate a plurality of different seating configurations. For instance, the one or more passenger seats can include a passenger seat defining a seating orientation. The passenger seat can be configurable in a first configuration in which the seating orientation is directed towards a forward end of the autonomous vehicle and a second configuration in which the seating orientation is directed towards a rear end of the autonomous vehicle. The passenger seat can include a seatback rotatable about a pivot point on a base of the passenger seat to switch between the first configuration and the second configuration. Alternatively, or additionally, the autonomous vehicle can include a door assembly pivotably fixed to a vehicle body of the autonomous vehicle such that a swept path of the door assembly when moving between an open position and a closed position is reduced.

Systems, methods, and devices for a vehicle door or window are disclosed herein. A vehicle includes a vehicle body and a cabin located within the body of the vehicle, wherein the cabin includes an interior that is configured to accommodate at least one person. The vehicle includes at least one seat located in the interior of the cabin that is configured for seating a user. The vehicle includes at least one door that provides ingress and egress to the interior of the cabin of the vehicle, and the at least one door is located with respect to the body such that the door opens to provide ingress and egress into the cabin from a backside of the seat.

Device for guiding a door element, for example, a sliding door for a passenger transport vehicle, has a first and a second guiding profiled element, wherein the two guiding profiled elements are arranged parallel to each other at a distance from each other, and three guiding elements in total, by means of which the door element is guidably connected to the two guiding profiled elements, wherein two of the guiding elements are guidably arranged on the first guiding profiled element and one of the guiding elements is guidably arranged on the second guiding profiled element.

A door control device is applied to a vehicle including a vehicle body having a first opening and a second opening adjacent to each other, a first door configured to open and close the first opening, a second door configured to open and close the second opening, a first drive unit configured to open and close the first door between a fully open position where the first opening is fully opened and a fully closed position where the first opening is fully closed, and a second drive unit configured to open and close the second door between a fully open position where the second opening is fully opened and a fully closed position where the second opening is fully closed. The door control device includes: a first control unit configured to control the first drive unit based on the operation command signal; and a second control unit configured to control the second drive unit based on the operation command signal, the operation command signal being a signal for operating both the first door and the second door. When the operation command signal is transmitted to the first control unit and the second control unit while the first door and the second door are stopped, the first control unit starts an operation of the first door and the second control unit starts an operation of the second door, and when the operation command signal is transmitted to the first control unit and the second control unit while at least one of the first door and the second door is in an opening and closing operation, the first control unit restricts the operation of the first door, and the second control unit restricts the operation of the second door.

A sealing system for a vehicle includes: a mounting member including a web, and a first flange and a second flange extending opposite to each other from the web; and a scaling member including a sealing body, and a first engaging portion and a second engaging portion integrally connected to the sealing body, where the first engaging portion and the second engaging portion oppose each other in relation to the web, the first engaging portion is elastically engaged with the first flange, and the second engaging portion is elastically engaged with the second flange.

An operator cab mounted on a chassis of a mobile work vehicle. The cab comprised of a frame supporting a back panel, a pair of opposing side panels, and a roof panel, wherein the side panels and the roof panel each have a first edge proximate the back panel and a second edge opposite the first edge, the second edges defining a door opening. A door proximate the door opening, the door movable to a closed position or an open position and defining a front barrier when in the closed position. A roller assembly positioned proximate the roof panel and connected to the door, wherein the door is moved about the roller assembly to an open position from the closed position, allowing for an operator to ingress and egress through door opening.

A door system (1) includes a door leaf (3) for closing off an entrance opening (4) and a suspension rod (10) having two opposite ends (11, 12) supported by a support structure (13). A suspension member (14) connects the door leaf (3) to the suspension rod (10) and can slide together with the door leaf (3) along the suspension rod (10) from an initial position corresponding to a closed position of the door leaf (3), to a final position corresponding to an open position of the door leaf (3). The two opposite ends (11, 12) of the suspension rod (10) are slidable in a horizontal direction transverse to the entrance opening (4). The suspension member (14) is slidably coupled to and guided by a non-linear upper guide (17) positioned above the suspension rod (10).
