Vehicle head

摘要

A superstructure module of a front-end section of a vehicle is supported on a chassis and includes a flow guiding device. The front-end section forms a leading, free vehicle end during normal operation of the vehicle. The flow guiding device is mounted on a lower side of the superstructure in the longitudinal direction of the vehicle between the free vehicle end and a leading end of a chassis. The flow guiding device influences air flow that flows during operation of the vehicle along the lower side of the superstructure from the free vehicle end to the chassis section. The flow guiding device via a deflection area confers on the air flow, in the region of a flow separation edge at the leading end of the chassis section, a downwardly directed direction of flow.

主权项

1. A wagon body module for forming at least a portion of a head portion of a wagon body of a vehicle supported on at least one running gear, comprising:
a flow guiding surface, said wagon body defining a vehicle longitudinal direction, a vehicle transverse direction and a vehicle height direction, said head portion being configured to form a leading free vehicle end during normal operation of said vehicle, said flow guiding surface being configured to be arranged, at a lower side of said wagon body, in said vehicle longitudinal direction between said free vehicle end and a leading end of a running gear cutout of said wagon body, the cutout receiving said running gear associated with said free vehicle end, and said flow guiding surface being configured to influence, during operation of said vehicle, an air flow which flows over said lower side of said wagon body from said free vehicle end towards said running gear cutout, wherein said flow guiding surface extends downwardly up to said leading end of said running gear cutout of said wagon body, said flow guiding surface is configured to impose to said air flow in a region of a flow separation edge at said leading end of said running gear cutout, by means of a deflection region, a downwardly directed main flow direction which is inclined relative to said vehicle longitudinal direction by at least 3° said flow separation edge is arranged so as to be spaced from said free vehicle end in said vehicle longitudinal direction by a separation edge distance, said flow guiding surface cooperates with said air flow and defines an envelope, and said flow guiding surface has a guiding portion adjoining said flow separation edge, extending between said free vehicle end and said flow separation edge and reducing, in said vehicle height direction, a free flow cross-section available for said air flow towards said flow separation edge, said guiding portion in said vehicle longitudinal direction extending over at least 10% of said separation edge distance, and/or said guiding portion has a guiding surface cooperating with said air flow, a tangent to said envelope in the region of said guiding surface, in a sectional plane extending perpendicularly to said vehicle transverse direction, being inclined relative to said vehicle longitudinal direction by at least a first angle of inclination of at least 3°, said first angle of inclination increasing in said direction towards said flow separation edge, and/or said guiding portion extending in said vehicle transverse direction over at least 80%, of a wheel gauge of said running gear, and said flow guiding surface has a diffuser portion located upstream of said guiding portion, extending between said free vehicle end and said guiding portion and increasing, in said vehicle height direction, a free flow cross-section available for said air flow towards said flow separation edge, wherein said diffuser portion is configured to allow said air flow that passes under said wagon body to be initially directed upwards so as to allow said diffuser portion to direct said air flow downwardly using said guiding portion.
