Abstract: A vehicle wheel for a vehicle has a plurality of spokes, lamellac, blades, wheel segments or similar which are arranged on an outer side of the vehicle wheel, a kinematic system, via which the contour of the outer side of the vehicle wheel can be changed, and a slide element which is adjustable between an inner position and an outer position. The spokes, lamellae, blades, wheel segments or similar are hinged on the slide element and are adjustable together with the slide element.

Abstract: A radiator grill arrangement for a motor vehicle front end of a motor vehicle with a number of air passage openings, which can be closed at least substantially by at least one flap element is provided. The at least one flap element is supported so as to be able to swivel about an associated flap axis. In driving states of the motor vehicle in which little cooling air is needed for the engine or engine compartment, the entire flap arrangement or a part of the flaps can thus be closed in order to improve the drag coefficient cw of the motor vehicle and to save fuel. Also in the parked state of the motor vehicle with the engine switched off, it is possible to close the flap arrangement in order to ensure a more aesthetically pleasing appearance of the motor vehicle.

Abstract: A motor vehicle rear end is delimited by a rear bulkhead, side wall regions, and a rear cover. An air separation edge extends on the rear cover in the width direction of the motor vehicle. Lateral rear lights are integrated into the motor vehicle rear end, and include means, which are arranged in the side wall regions, for release of the side wall flow, and which extend at a distance below the air separation edge over a height region of the associated rear light (20) and at a distance from the rear bulkhead. At least one opening, through which air flows, is provided in a covering element arranged at the end of an air duct as a means for release of the side wall flow in both side wall regions.

Abstract: The invention relates to a radiator grill arrangement (10, 10?) for a motor vehicle front end of a motor vehicle, which comprises a plurality of air passage openings (16), which can be closed at least substantially by at least one flap element (20). In the embodiment according to the invention, the at least one flap element (20) is thereby supported so as to be able to swivel about an associated flap axis (24). In driving states of the motor vehicle in which little cooling air is needed for the engine or engine compartment, the entire flap arrangement or a part of the flaps (20) can thus be closed in order to improve the drag coefficient cw of the motor vehicle and to save fuel. Also in the parked state of the motor vehicle with the engine switched off, it is possible to close the flap arrangement in order to ensure a more aesthetically pleasing appearance of the motor vehicle.

Abstract: A chassis and/or supporting structure of a motor vehicle, in particular of a passenger vehicle, is entirely or partially designed as a hollow chamber sheet structure.

Abstract: The invention relates to an air control system in the front end of a motor vehicle with openings in a front wall defining the front end, through which cooling air flows into a motor compartment. Air ducts (6, 10, 11, 18) are provided which feed the cooling air into athe motor compartment, substantially against the direction of travel and which are formed by boundary walls (7, 19) running approximately parallel to the direction of the air flow. It is therefore the task of the invention that an air guidance is created in the front end of a motor vehicle while assuring a low-loss flow, in which the assembly is substantially simplified. According to the invention, the boundary walls (17, 19) are integrated into a body panel (1) which extends appromately across the direction of air flow in the motor compartment.

Abstract: A wind deflector for a sliding roof opening of a motor vehicle having a projected wind deflector profile that is raised in relation to the front roof cutout edge and that experiences the flow-through of the air flow during travel when the sliding roof is open. The deflection profile is equipped on one face side with a series of air inlet ports, arranged over its breadth, and with air outlet ports on an adjacent profile side. The wind deflector profile is realized as a hollow section, and air outlet ports are distributed across the upper boundary wall of the wind deflector profile.

Abstract: An air guide housing, for a fan impeller of a radiator of internal combustion engines, includes a cowl ring arranged downstream on the radiator and having at least one radial outflow opening. The fan impeller is overlapped at least partially, in the axial direction, by the cowl ring. In order to achieve an improvement in the guiding away of the air and thereby reduce pressure losses in the outflow from the fan, even in the case of restricted installation spaces, guide vanes are provided in the region of the outflow openings.
