Description

The present invention relates to the technical field of rideable saddle vehicles, such as motorcycles, and in particular to rideable saddle vehicles with windshields.

It is known to provide a rideable saddle vehicle, particularly a motorcycle or scooter, with a windshield to at least partially protect the driver from wind, rain and atmospheric agents. Generally, the windshield is fixed to the front shield of a rideable saddle vehicle, especially to the top of the front shield.

Background art rideable saddle vehicles suffer from the drawback that during operation of the vehicle, particularly at high speeds, the air that is obstructed and deflected head-on by the windshield creates turbulent airflow towards the driver's helmet. This air turbulence begins at the top of the trailing edge of the windshield. Air turbulence also exerts force on the helmet and is a source of noise, thus adversely affecting ride comfort.

The object of the present specification is to produce a rideable saddle vehicle with a windshield that can overcome or at least partially reduce the above drawbacks.

This object and other objects are achieved by a saddle vehicle according to claim 1 . Preferred and advantageous embodiments of the vehicle are described in the attached dependent claims.

The invention will become apparent from the following detailed description of particular embodiments, by way of description and by no means limiting, in connection with the accompanying drawings, which are described in conjunction with the following paragraphs.

The following description of one or more embodiments of the invention refers to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements. The drawings do not necessarily have to be shown to the same scale. Also, the following detailed description should not be taken as limiting the invention itself. The objects of the invention are defined by the appended claims. Unless it is clearly indicated from the following description that some features or solutions are alternatives to each other, or that it is not clear from the following description that two or more features or embodiments are mutually exclusive, Technical details, structures or features may be combined with each other in any way.

In the following description, "upper", "lower" or similar terms refer to the bike 1 in normal conditions of use, unless indicated otherwise. In this condition of use the bike is in a vertical position.

For the purposes of this specification, the term "windshield" is described as generally meant to include, for example, a "windshield fairing". This "windshield fairing" is typically small relative to common windshields and is configured to withstand air pressure at speeds greater than those for which common windshields are designed.

The accompanying drawings 1-6 show an embodiment of a rideable saddle vehicle 1. FIG. The vehicle 1 is a motorcycle 1, in particular a scooter 1. In particular, the illustrated example shows a bike 1 embodiment. This bike 1 takes the form of a three-wheeled bike or tricycle with two steerable front wheels 101, 102 and one rear wheel 103, without introducing any limitation.

Hereafter, reference is made to a generic rideable saddle vehicle 1, abbreviated as bike 1. As shown in FIG. The following description is generally applicable to any type of vehicle 1 .
This vehicle 1
support structure,
at least two wheels 101, 103 directly or indirectly constrained to the support structure;
a traction motor, e.g. thermal, electric or hybrid, constrained to the support structure and operatively connected to at least one of the two wheels 101, 103;
and a rideable saddle 104 secured to the support structure.
That is, it should be noted that the teachings herein are generally applicable to all rideable saddle vehicles having two, three, four or more wheels. The windshield can be attached to this saddle vehicle, such as, but not limited to, a motorcycle, moped, scooter, all terrain vehicle (ATV), and the like.

A motorcycle 1 comprises a front part 2 and a windshield 3 fixed to the front part 2 . The front part 2 is preferably part of the body of the bike 1 and more preferably part of the aforementioned front shield of the bike 1 . The front shield is configured to cover at least a portion of the front side of the bike 1, as is known. According to a preferred embodiment, the windshield 3 has an inner side 3A facing the front part 2, an outer side 3B facing the front part 2, a lower end 3C, an upper facing end 3D, and the lower end 3C and the upper end 3D are connected respectively. It has a pair of side ends 3E, 3F. The windshield 3 is removably fixed to the front part 2, preferably by mounting screws 14 (FIG. 4), for example four mounting screws 14. FIG. In particular, the windshield 3 is fixed to the front part 2 so as to have a predetermined inclination. That is, the bike 1 does not have elements for adjusting the tilt of the windshield 3 in different positions. The front part 2 and the windshield 3 are arranged to form a duct 4 for conveying air and during operation of the bike 1, an air flow F1 (shown by the line in FIG. 3 and the arrow in FIG. 5). flow F1). The duct 4 comprises, in particular, an inlet 5 arranged to direct the air flow F1 into the duct 4 . The duct 4 also comprises an outlet 6 configured to allow the exit of the air flow F1 from the duct 4 itself. Preferably, the inlet 5 and outlet 6 are centrally located with respect to the front part 2 of the bike 1 and with respect to the windshield 3 . The inlet 5 is at least partially formed by the lower end 3C of the windshield 3 . Inlet 5 and outlet 6 each have an inlet section 5A and an outlet section 6A. In particular, inlet section 5A is larger than outlet section 6A. According to a suitable embodiment, the lower end 3C of the windshield 3 is shaped to concentrate the air flow F1 towards the inlet section 5A of the duct 4. It should be noted that the term "duct" is used to define the duct 4 and is generally indicated. That is, the duct 4 is a channeling configured to direct the dominant portion of the air flow F1. This air flow F1 enters through inlet 5 . That is, duct 4 is not necessarily a completely sealed duct in a direction perpendicular to the dominant direction of flow F1. Part of the air flow F1 thus leaks laterally out of the duct 4, for example if there is a space through which part of the air flow F1 can pass. It should be noted that the term "section" used to define parts of the duct 4, in particular the inlet section 5A and the outlet section 6A, means the area through which the duct 4 passes. This passage area is perpendicular to the dominant direction of the air flow F1. Preferably, inlet section 5A is a free section, ie a passage area without grids or other elements. This passage area may impede or define the load losses of the air flow F1. Preferably, outlet section 6A is also a free section.

According to a preferred embodiment the duct 4 is a centralized duct 4 . In particular, ducts 4 converge in the direction from inlet 5 to outlet 6, indicated by arrow V1 in FIG.

It should be noted that the air flow F1 can be accelerated by providing the duct 4, preferably forming the duct 4, with a larger inlet section 5A than the outlet section 6A so as to concentrate in said duct. Air flow F1 can thus divert air flow F2 (FIG. 3). This air flow F2 overlaps the outer surface 3B of the windshield 3 such that the streamlines of the flow F2 adhere to the windshield 3 at the trailing edge, ie, the upper end 3D of the windshield 3 . This advantageously reduces turbulence, propulsive effects and unwanted noise in the helmet H1 of the driver C1 during operation of the bike 1 to improve ride comfort at high speeds, for example above about 90 km/h. can be greatly improved.

According to a preferred embodiment, the duct 4 is arranged to carry the airflow F1 out of the outlet section 6A and upwards along the tangential direction of the inner surface 3A of the windshield 3 . This advantageously provides an upward offset of the airflow F2 to improve the turbulence reduction effect in the helmet H1 of the driver C1.

According to a preferred embodiment, the front part 2 of the bike 1 comprises two protruding fixed supports 7, 8 to which the windshield 3 is fixed. In particular, the duct 4 has a bottom, a top and a side, the bottom being formed by the front part 2, the top being formed by the inner surface 3A of the windshield 3, and the sides being formed by the protruding fixed supports 7,8. It is Preferably, the projecting fixed supports 7, 8 are arranged parallel to each other. Alternatively, the projecting fixed supports 7, 8 may be arranged so as to stray in the direction V1, in particular transversely to the direction V1. In this case, preferably the projecting fixed supports 7, 8 diverge from each other so as to carry the air flow F1 towards the entire upper end 3D of the windshield 3 . This advantageously evenly distributes the airflow F1 exiting the outlet 6 towards the helmet H1 of the driver C1 and also results in a favorable effect on the ride, as well as a thrust force on the helmet H1 itself. can be uniformly distributed.

According to an embodiment, the protruding fixed supports 7, 8 each have a front part 7B, 8B close to the inlet 5. FIG. This inlet 5 is shaped to form a channel for moving the air flow F1. According to an embodiment, the respective front portions 7B, 8B of the protruding fixed supports 7, 8 are arranged such that a portion of the air flow F1 is directed towards the pair of handles 10, 11 of the handlebar 9 of the bike 1. It is arranged at a predetermined distance from the inner surface 3A of the windshield 3. Therefore, part of the airflow F1 can move between the inner surface 3A of the windshield 3 and the front portions 7B, 8B of the projecting fixed supports 7, 8 by deflecting the airflow. This airflow overlaps the outer surface 3B of the windshield 3 in a direction transverse to the flow F2 so as to reduce turbulence in the area affecting the hands and forearms of the driver C1. Therefore, the riding comfort of the bike 1 is further improved.

According to a preferred embodiment, the front part 2 of the bike 1 is part of the front shield of the bike 1, as described above. The projecting fixed support portions 7 and 8 and the front portion 2 are connected to each other by integral molding. That is, the projecting fixed support portions 7 and 8 and the front portion 2 are preferably integrally formed. This can expediently reduce the side losses of the air flow F1 to maximize the positive effect of said flow F1 on the ride quality.

According to an embodiment, the side edges 3E, 3F of the windshield 3 are laterally shaped so as to at least partially form a pair of handguards. In this regard, Applicants have found that the shaping of the side edges 3E, 3F isolates the airflow overlying the outer surface 3B of the windshield at the trailing edge corresponding to the pair of handguards and reduces turbulence downstream of the trailing edge. It has been found that while increasing the flow, the increased turbulence occurs in areas that do not adversely affect the hands and forearms of driver C1. Therefore, the riding comfort of the bike 1 is further improved.

According to an embodiment, the windshield 3 comprises a pair of longitudinal reinforcing folds 12, 13 extending from the lower edge 3C towards the upper edge 3D of the windshield 3. As shown in FIG. It should be noted that fold lines 12, 13 are folded. The folds 12, 13 are not steps, but gradually connect the two parts of the windshield 3 to form a fold with a rounded cross-section.

Based on the foregoing, one can appreciate how a rideable saddle vehicle of the type described above can achieve the objectives of the background art.

Without detracting from the principles of the invention, the embodiments and details thereof may vary widely with respect to what has been described by way of non-limiting example without departing from the scope of the invention as set forth in the appended claims. .
