An air inlet shut-off device for a motor vehicle having: a support frame defining a passage opening for an incoming air flow, a curtain movable between a closed position and an open position, an automatic return system for the curtain having: an elastic element which is elastic in elongation along the rolling axis of the roller shaft and secured to the latter in such a way as to be rotated and vice versa; a cylindrical slider intended to move in translation along the rolling axis and in rotation about this same axis, said slider being secured to the elastic element in such a way as to be rotated indirectly by the roller shaft, said slider including a helical groove on its outer surface, the support frame including a fixed finger configured to be inserted in said helical groove.

A truck or tractor semi-trailer combination interconnected via a fifth wheel, comprising a cabin and an air collection chamber, the air collection chamber provided between a rear end of the cabin and the semi-trailer and having a front wall substantially adjacent or identical to a cabin rear wall, and a rear wall distanced and substantially coplanar to the front wall, which air collection chamber is provided with an air accession structure and a heat exchanger, the air accession structure providing air access to the air collection chamber and towards the heat exchanger, said heat exchanger provided in the rear wall of the air collection chamber extending at least partly over a width of the truck and wherein said air accession structure comprises air accession side ports provided on the side walls of the air collection chamber designed to provide at least a passive air flow from the air accession side ports towards the heat exchanger.

A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.

Vehicle wheel attachments that are installed and removed easily and are capable of being individually removed and adjusted. These vehicle wheel attachments direct airflow out of the interior of the wheel well.

Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

An active air flap device for a vehicle may include: a housing part mounted in a bumper cover part; one or more flap parts rotatably mounted in the housing part, and exposed to the outside through a hole formed in the bumper cover part to form the same skin line as the bumper cover part; a link part connected to the flap part; a loader part mounted in the link part; and a driving part configured to rotate the loader part.

The invention relates to a shut-off flap (26) for a motor vehicle shut-off device, notably for a device for shutting off an air inlet in the front face of a motor vehicle, comprising a flap body (28), the flap body (28) being at least partially made of a fibre reinforced composite material, notably one that uses continuous reinforcing fibres (42, 44). The invention also relates to a motor vehicle shut-off device comprising such a flap and to methods of manufacturing this flap and this shut-off device for a motor vehicle.

An adjustment device for controlling the aerodynamic load acting on a motorcar, includes an underbody diffuser.

Methods and systems for operating a transport climate control system of a vehicle are provided. The method includes obtaining a state of charge of an energy storage device capable of providing power to the transport climate control system; determining an energy level including the state of charge, receiving a planned route for the vehicle, and receiving route status data associated with the planned route for the vehicle. The route status data includes traffic data, weather data, and/or geographic data identifying areas where the transport climate control system is to be solely powered by the energy storage device. The method further includes determining whether the energy level is sufficient to complete the planned route for the vehicle based on the planned route and the route data, and when the energy level is not sufficient to complete the planned route for the vehicle, providing a notification to a user via a display.

An assembly includes multiple structures and a first bracket. The multiple structures include at least a first structure, a second structure, and a third structure located between the first structure and the second structure. The first bracket is configured to fix the second structure to the first structure and support the third structure. The first structure, the second structure, and the third structure are arranged in a first direction. The first bracket includes a second structure supporting portion supporting the second structure and a third structure supporting portion supporting the third structure. The second structure supporting portion is located on a first side of the first bracket and the third structure supporting portion is located on a second side of the first bracket. The first side and the second side are opposite to each other in a second direction perpendicular to the first direction.
