Definitions

• the invention relates to the field of industrial vehicles, and more specifically trucks. It relates to a body element of a vehicle door, making it possible to channel and direct an air flow towards the high parde of the front wheel arch.
• It relates more particularly to a means making it possible to prevent dirt projected by the wheel from coming to settle in a lateral zone of the cabin on, and downstream of the door.
• the device disclosed in US 4,624,497 comprises two clement disposed on cl side of the motor cooling radiator, on the front ace.
• This type of device also called an air deflector, improves the aerodynamic performance of the vehicle.
• devices have also been designed to channel the air arriving frontally on the front face of the vehicle and which is therefore deflected perpendicularly to the direction of advance of the vehicle.
• These devices are, as described in particular in the documents US 3,836,191, DE 40 14577, JP 2001 122162 and US 5171 057, attached at the level of the round corner of the front face.
• the air flow thus arriving parallel to the front face of the truck is thus deflected parallel to the direction of advance of the truck. Pressure losses, but also turbulence are then generated by this deflection of the air flow.
• these devices comprise either only a deflector at the level of the round corner so as to reject an air flow at an area remote from the wheel arch, or both a deflector and a pipe added in the door for allow the air flow to be directed towards the upper part of the wheel arch.
• This pipe must then be connected to the round corner deflector, which also generates, at the level of the connection area, pressure drops and turbulence.
• the object of the invention is therefore to channel an air flow towards the upper part of the wheel arch of the cabin of an industrial vehicle, and this, with the maximum efficiency and the minimum possible turbulence.
• the invention therefore relates to a bodywork element for an industrial vehicle door. It is characterized in that it comprises an air intake and channeling tube, the front opening of which opens towards the front of the vehicle and the rear opening of which faces towards the upper part of the passage. wheel.
• tubing of caplalion and air duct csl lolalcmenl mobile with the door relative to the cabin of the industrial vehicle.
• Its front opening is inscribed in a substantially vertical plane which is perpendicular to the longitudinal direction of the vehicle and is located laterally with respect to the front face. Uptake is the therefore has frontally, generating almost no deviation from the surrounding air.
• Its rear opening is oriented so that it prevents dirt projected by the wheels to settle in a lateral area of the cabin on, and downstream of the door.
• the body element can directly be produced or integrated into the body of the door.
• the door and the bodywork element forming the tubing are one.
• the bodywork element can be an attached part attached to the door.
• the bodywork element forming the tubing must be secured to the door by means of attachment, such as screws, rivets or by means of bonding or especially welding.
• the tubing may also include at least one fin for directing the air flow passing through the tubing.
• the fins are arranged at the front opening of the tubing, and can even partially emerge from this opening.
• the main orientation of the fins is horizontal, that is to say that when the air flow passing through the tube is not deflected at the inlet, the fins are arranged horizontally.
• They can be arranged one above the other in parallel; in this case, they are then regularly or not spaced.
• the fins are then provided with a horizontal axis of rotation included in a plane parallel to the plane of the front opening of the tube.
• the orientation of the fins is then obtained by pivoting around this horizontal axis of rotation.
• Means can be used to connect the different fins together, in order to give the same orientation to all the fins when the orientation of one of the fins is changed.
• the cross-sectional area of the tubing can be constant. Thus, the pressure of the air flow passing through the tubing is not modified.
• the cross-sectional area of the tubing can be decreasing, from its front opening towards the rear. In this way, an increase in speed is created in the upper part of the wheel arch repelling the emission of turbulence.
• the tubing does not form too large a protrusion at the door, it may be advantageous that the rear opening of the tubing opens into a recess in the door by flush with the tubing.
• the front opening of the tubing may be located at the front edge of the door body. It may also be conceivable to combine the invention with other aeraulic elements of the front face of the vehicle making it possible to channel air towards the front opening of the pipe. This combination then makes it possible to improve the capture of the air at the level of the front opening of the tubing without nevertheless substantially deflecting the air flow passing through the tubing.

• the invention relates to an element of the bodywork of an industrial vehicle door, aiming to prevent soiling projected by the wheel from being deposited in a lateral zone of the cabin on, and downstream of the door.
• the door (1) of the industrial vehicle is equipped with a door body element. It comprises a tube (2) produced in the body of the door (1).
• the invention is not limited to this principle of realization.
• the tubing (2) can indeed also be an insert on the door (1) of the industrial vehicle.
• the tubing has a front opening (3) oriented towards the front of the vehicle.
• This opening (3) can more precisely be situated at the level of the front edge of the body of the door (1). It also has a rear opening (4) oriented towards the upper part of the wheel arch (5) of the industrial vehicle. In this way, it is avoided that the dirt projected by the wheel is deposited in a zone (8) located downstream and on the door.
• the front opening (3) is, in turn, provided with fins (6) making it possible to orient the air flow passing through the tube (2).
• the fins (6) have a generally horizontal orientation and are positioned one above the other.
• the fins (6) have an axis of rotation about which they can pivot, so as to orient the air flow.
• the fins (6) are provided with means making it possible to provide the same orientation to all the fins (6).
• these means make it possible to orient the fins (6) in the same direction while handling only one fin (6).
• the rear opening (4) of the tube (2) opens, in turn, into a recess (7) of the door (1). In this way, and as shown in Figure 2, the protrusion generated by this tubing (2) integrated in the door (1), is minimized. Consequently, the aerodynamic qualities of the vehicle are not compromised.
• the fins (6) partially emerge from the front opening of the tubing (2). Their orientation is possible around a substantially horizontal central position.
• the cross-sectional area of the tubing (2) is constant. In this case, the pressure of the air flow passing through the tubing (2) is not changed. The angle of incidence of the air flow arriving at the upper level of the wheel arch (5) is then simply modified.
• the invention is not limited to this unique configuration. Indeed, the cross-sectional area of the tubing (2) can also be decreasing by going backwards.
• This figure also makes it possible to show that the rear opening (4) of the tube (2) opens into a recess (7) of the door (1). In this way, the channeling of the air flow towards the upper part of the wheel arch (5) generates little or no protrusion at the door (1) of the vehicle.
• a door body element according to the invention has multiple advantages, in particular:
