Problems solved by technology

A disadvantage of this cooling air assembly is, inter alia, that the air intake opening is always open and, depending on the driving state or the inflow speed of the air, leads to an undesirably high propulsion resistance and / or front axle lift.

Embodiment Construction

[0035] exist figure 1 and 2 A motor vehicle front 10 of a motor vehicle with a front inclination greater than 15° is shown in FIG. In the motor vehicle head 10 are arranged a heat exchanger 20 , an electric fan 22 arranged downstream of the heat exchanger 20 , and a cooling air assembly for controlling the air supply to the heat exchanger 20 . The cooling air assembly guides and controls the upper air path 32 and the lower air path 50 , both of which can lead to the heat exchanger 20 if necessary.

[0036] The upper air path 32 essentially consists of an upper, forwardly opening inlet opening 30 having a controllable flap arrangement 34 for fluidically opening or closing the inlet opening 30 . The upper air path 32 is arranged above the horizontal body part 12 designed as a bumper and approximately at the level of the heat exchanger 20 .

[0037] Below the horizontal body part 12 there is provided an essentially downwardly opening air intake opening 42 which is associated w...

Abstract

The invention relates to a motor vehicle front end, and the end has a heat exchanger (20) and a cooling-air mechanism for controlling a supply of air to the heat exchanger (20). The cooling-air mechanism includes: a downwardly opening air inlet opening (42); and an air flap (40), which corresponds to the air inlet opening (42), and which, at its top edge, is articulatable on a body part in a pivotable manner via a pivot joint. The air flap (40) is configured such that, in its closed position, it closes off the air inlet opening (42), and in its operative position, it opens up the air inlet opening (42), and as seen in a direction of travel of the motor vehicle, is situated in front of the air inlet opening (42).

Description

technical field [0001] The invention relates to a motor vehicle head, especially for motor vehicles with a frontal inclination greater than 15°, having a heat exchanger and a cooling air assembly for controlling the air supply to the heat exchanger. Background technique [0002] The cooling air assembly of the motor vehicle head can have, as the sole or additional air intake, a downwardly opening air intake opening which is usually arranged under the front bumper. A downwardly opening air intake opening is understood here to be an air intake opening which opens largely downwardly and not only forwardly, so that its opening plane is inclined forward by less than 60° with respect to the horizontal. [0003] From DE 10 2015 105 567 A1 a cooling air assembly is known, which has an air intake opening below and opens obliquely downwards, which cooling air assembly is equipped with a spoiler which, in the rest position, faces inwards Flips over and is aerodynamically inactive, and...
