A motor vehicle with an automatically adjustable front wing and with an automatically adjustable rear wing, which are each adjustable in a controlled manner by an actuator. The motor vehicle has a front axle with front wheels and a rear axle with rear wheels. By way of the adjustment of the front wing and/or the rear wing, a downforce is caused on the front axle due to the inflow of air onto the front axle, and a downforce on the rear axle is caused due to the inflow of air onto the rear axle. A resulting downforce passing through a point can be produced, and an aero balance can be adjusted. The downforce on the front axle, the downforce on the rear axle, the resulting downforce, and/or the aero balance can be controlled and/or adjusted automatically and/or manually.

A motor vehicle with an automatically settable front wing and an automatically settable rear wing, each of which is settable under the control of an actuator. Owing to the incident flow of air at the front axle, a downforce at the front axle (FDF) can be set by positioning the front wing. Owing to the incident flow of air at the rear axle, a downforce at the rear axle (RDF) can be set by positioning the rear wing. A resultant downforce (DF) acting through a point (CoP) can be generated and an aero balance (AB) can be set. The rear wing and/or the front wing can be set automatically in dependence on an operating state of the motor vehicle such that a predetermined downforce (FDF) at the front axle, a predetermined downforce (RDF) at the rear axle, a predetermined resultant downforce (DF) and/or a predetermined aero balance (AB) is obtained.

A vehicle roof having a roof opening system having a cover element which is displaceable between a closed position, in which a roof opening is closed, and an open position, in which the roof opening is open; displacement kinematics for displacing the cover element on either side of a vertical longitudinal center roof plane, each displacement kinematics may have a guide rail, a first kinematic unit guided in the guide rail, and a second kinematic unit guided in the guide rail; and a set of drive cables for the two kinematic units, the first kinematic unit may have a first deploying lever which is adjustable between a raised position and a lowered position, and the second kinematic unit may have a second deploying lever. The first kinematic unit has a securing slide which is guided in the guide rail and secures the first deploying lever in its lowered position.

A wheel casing including a body portion configured to be positioned along an inboard sidewall of a tire having an axis of rotation and at least a front strake positionable over tread of the tire. The front strake having a first edge adjacent the body portion and extending outwardly to a second edge of the front strake that terminates at or inboard of an outboard side of the tire, the front strake defining a lower edge and an upper edge, the lower edge and the upper edge both configured to be positioned forward of the axis of rotation, and tread of the tire positioned rearward of the upper edge is uncovered by the wheel casing.

A process of making a drag-reducing aerodynamic vehicle system includes injection molding a body configured for attachment to a roof of a vehicle with a sliding core, wherein the body comprises an air inlet extending through a surface of the body, wherein the air inlet includes an air guide boss extending from an interior surface of the body, wherein the air guide boss adjusts an air stagnation point away from the windshield to reduce air pressure and drag on the vehicle; and ejecting the drag-reducing aerodynamic vehicle system from the injection mold using the sliding core.

A spoiler mechanism (13) for a vehicle (10) includes a spoiler (16) that has a stowed position and first and second deployed positions. An actuator (22) is configured to move the spoiler (16) though the stowed and first and second deployed positions in response to a command. A multi-link assembly (20) is interconnected by pivot points. The multi-link assembly (20) is operatively connected to the spoiler (16). In the first deployed position at least three pivot points are aligned with one another in a plane and provide a first geometrically locked position. In the second deployed position a second geometrically locked position is provided in which a link of the multi-link assembly (20) abuts another structure.

This invention provides aerodynamic structures for the rear of a cargo body that move between a deployed position and a retracted position. The aerodynamic structures are typically three-sided, with a top panel and opposing side panels that form a partial cavity at the rear of the body. The panels employ tensioned flexible (e.g. fabric) panels or rigid/semi-rigid panels that are stowed, rolled, or folded in a retracted position against the rear of the door frame (for flexible panels) of the cargo body, or along the sides of the cargo body (for rigid/semi-rigid panels). The rigid/semi-rigid panels can be stored within nacelles that protect the panels and improve aerodynamic performance. Various linkages, including rotating rigid members attached to the rear of the body can coordinate movement between a top panel and side panels between deployed and retracted positions and a variety of powered and non-powered actuators can facilitate panel movement.

Systems, methods, and devices for a vehicle windshield are disclosed herein. A vehicle includes a vehicle body comprising a front, a first side, and a second side, wherein the first side and the second side are opposite one another on the vehicle body. The vehicle comprises a cabin located within the body of the vehicle, wherein the cabin comprises an interior that is configured to accommodate at least one person. The vehicle comprises at least one door that provides ingress and egress to the interior of the cabin of the vehicle. The vehicle comprises a windshield that provides a visual line of sight out of the cabin for a user located within the interior of the cabin, and wherein the windshield extends across the front and at least partially on to at least one of the first side or the second side.

An air fairing device is connected below the bottom a frameless trailer to improve aerodynamic efficiency and improve fuel economy. One embodiment of the air fairing device provides an air deflector positioned forward of a trolley which supports the frameless trailer at a rear end. A second embodiment of the air fairing device provides two deflectors mounted below the frameless trailer. The first deflector is attached and extends downward from an articulating arm, said arm connecting the trailer to a semi-tractor or truck. The second deflector connected to below the bottom of the frameless trailer and positioned rear of the first deflector and forward of the trolley. A third embodiment is similar to the second but further includes a third deflector positioned between two axles of the trolley.
