Air guiding element

摘要

An air guiding element for improved flow over a gap between a tractive vehicle and a trailer vehicle is described, wherein the air guiding element can be mounted on the tractive vehicle or the trailer vehicle and has a flexible and airtight air cushion which is connected to a filling channel. The problem of providing a largely low-maintenance and operationally safe air guiding element, which can be installed independently of the compressed air supply of the tractive vehicle, for improved flow over the gap between a tractive vehicle and a trailer vehicle is addressed. The problem is solved by an air guiding element in which the filling channel has an air entry opening oriented in the direction of travel (F) on the side of the filling channel facing away from the air cushion, the air entry opening being arranged in such a way that the air cushion is filled exclusively by a dynamic pressure of the relative wind.

1. An air guiding element for improved flow over a gap between a tractive vehicle and a trailer vehicle, wherein the air guiding element can be mounted on the tractive vehicle or the trailer vehicle and comprises: a flexible and airtight air cushion, which is connected to a filling channel, wherein the filling channel has an air entry opening oriented in the direction of travel (F) on a side of the filling channel facing away from the air cushion, said air entry opening being arranged in such a way that the air cushion is filled exclusively by a dynamic pressure of a relative wind, wherein the air cushion entirely fills the gap within an outer cross section contour of a boxlike body of the tractive vehicle, and wherein the air enclosed in the air cushion can flow from the inside of a curve, wherein the volume is smaller on account of the tractive and trailer vehicles coming close together, to the outside of the curve with a large volume.
