ROAD CAR WITH OPEN ROOF AND FLOW DIVERTER

Description

“ WE TT URAROADCONTE TT OOPENINGANDFLOW DIVERTER ” The present invention relates to a car road. In particular, the present invention relates to a road car of the type comprising a chassis support defining at least part of a lower floor of the road car; and a passenger compartment, which protrudes towards 17high from the lower floor, and is housed in its own inside at least one pair of seats. The passenger compartment is limited by a front windshield mounted inside a support ring provided with a pair of side uprights connected to each other by a upper crosspiece, and is also limited by a single openable configured to attach to the crosspiece top of the support ring itself. The highway vehicle also includes a diverter of flow to divert the flow outside the passenger compartment of air fed along the front windshield during the road car brand. Generally, 11 flow diverter includes one fixed spoiler protruding upwards from the crossmember upper or a movable spoiler configured to move, compared to the passenger compartment and under the push of a device drive, between a position and an evated position, in which 1 lo spoiler protrudes upwards from the upper crossmember, and a lowered position. The known road cars of the type described above they present some drawbacks mainly descending from the fact that the fixed spoiler protrudes upwards from the upper crosspiece even when the sunroof is closed and that the movable spoiler actuation device is relatively complex and expensive. The purpose of the present invention is to provide a road vehicle that is free from the above drawbacks exposed and that is simple and economical to make. According to the present invention, a road vehicle as claimed in the claims attached. The present invention will now be described with refer to the drawings nn and ss i, which in the strange one non-limiting implementation example, where: Figure 1 is a schematic perspective view, with parts removed for clarity, of a preferred form of implementation of the road vehicle of this invention; Figures 2 and 3 are two schematic side views, with parts in section and parts removed for clarity, of a detail of the road car in figure 1 illustrated in two different operating positions; Figures 4 and 5 are two schematic side views, with parts in section and parts removed for clarity, of a first variant of the detail in figures 2 and 3 illustrated in two different operating positions; Figures 6 and 7 are two schematic side views, with parts in section and parts removed for clarity, of a second variant of the detail in figures 2 and 3 illustrated in two different operating positions; and Figures 8 and 9 are two schematic side views, with parts in section and parts removed for clarity, of a third variant of the detail in figures 2 and 3 illustrated in two different operating positions. Refer to Figure 1 , with 1 is indicated , in the its complex, a road vehicle comprising a chassis 2 of support defining at least part of a floor 3 inferiore the car 1 ; unabitacolo 4 , which is mounted on frame 2, and protrudes upward from the floor 3 same; a front axle provided with two wheels 5 anterior; and a rear axle provided with two wheels 6 earlier posts. The table 1 further comprises an engine 7 propellant of a known type, in the case of an engine to internal combustion , which is mounted , in fact , flooding zone 8 anterior to frame 2 , and is with the egatoconle 5 front wheels to move the car forward 1 in a direction 9 of advance. The passenger compartment 4 is equipped with two doors 10 of a cc e ss o , and is limited by a front windshield 11 mounted inside a support ring 12 comprising two lateral uprights 13 connected to each other by a 14 upper crosspiece. The passenger compartment 4 is closed by a movable sunroof 15 between an open position (not shown) and a position closed (figure 1), in which the roof 15 is coupled to fluid seal at crosspiece 14 through 1'interposition of a gasket 16 (figure 2). As illustrated in figures 2 and 3, The passenger compartment 4 is provided with a trim band 17, which extends along crossroads 14, and includes a fixed portion 18 fixed on the crosspiece 14 and at least one mobile portion 19 configured to move relative to the fixed portion 18 between a lowered position, in which the fixed portion 18 and the movable portion 19 are essentially complete narifraloro, and a position so ll evata , in which the movable portion 1 9 is inclined towards 1"higher than the ©fixed portion 18 ©to deviate outside the passenger compartment 4 the air flow is fed along the windshield 11 while the car 1 is moving. Obviously, the movable portion 19 is moved in the a its raised position when the roof 15 is open. In this case, the mobile portion 1 9 is hinged to the fixed portion 18 to rotate, with respect at the fixed portion 1 8, at now at a fixed portion 2 0 of fulcrum substantially transversal to direction 9. The portion 19 is moved around the axis 20 between its lowered position and its raised position by a pneumatic actuation device 21 comprising a containment profile 22, which extends 1l along at least the crosspiece 14, is made of metal material, and has a substantially U-shaped shape with a concave facing upwards. Obviously, according to a variant not illustrated, the profile 22 can be made of different materials from a metallic material and / or be 1integrated into, and reali zz atoinunsolpe zz oconla , crosspiece 1 4 . The pr of i side 22 houses inside it a element 23 inflatable tubular, which is closed axially at its ends, and is connected with a 24 pneumatic power supply device, in the in this case an electrically operated pump, via 1' interposition of a pneumatic circuit 25. Circuit 25 extends along at least part of the “ring 12, and is connected to the element 23 via 1' interposition of an inflation valve 26. Device 24 and valve 26 are configured to inflate element 23 into a final configuration (figure 3), wherein the element 23 protrudes upwards from the crosspiece 14 and from the profile 22 to move the movable portion 19 in its raised position, and to deflate the 1'' element 23 in an initial configuration (figure 2), where element 23 is folded substantially inside of the profile 22 and of the crosspiece 14 to move the movable portion 19 in its lowered position. The variant illustrated in figures 4 and 5 differs from what is illustrated in the previous figures only for the fact that, ine ssa , the device 2 1 drive tire is removed and replaced with a device 27 of electric drive comprising an actuator 28 linear. The actuator 28 comprises an electric motor 29, the which is fixed to the crosspiece 1 4 , and is provided with a output shaft (not shown) coupled via a screw-nut coupling to a 30 transmission rod having a free end hinged to the portion mobile 19. The variant illustrated in figures 6 and 7 differs as illustrated in Figures 2 and 3 only for the makes eyes , inessa , 1 the band 1 7 of lining comes removed and replaced with a band 31 of coating real zz materials are also elastic. deformable. The band 31 extends 1along 1the crossbar 14, and comprises a fixed portion 32 fixed to the crossbar 14 and at least one moveable portion 33, which is made in a single piece with fixed portion 32, and is configured for move with respect to the fixed portion 32 between a position a bb a ss ata , incubaportionfi ssa 3 2 exportable 33 substantially planned between 1 them , eduna position of the evata , in which the movable portion 33 is inclined upwards with respect to the fixed portion 32 for divert the air flow outside the passenger compartment 4 powered along the windshield 11 while driving the car 1. Obviously, the movable portion 33 is moved in the its raised position when the roof 15 is open. The movable portion 33 is elastically deformed between its ©positions lowered and raised by a pneumatic actuation device 34 of the whole equivalent to pneumatic actuation device 21. The variant illustrated in figures 8 and 9 differs as illustrated in figures 6 and 7 only for the fact , ine ssa , 11 device 3 4 drive tire is replaced by a 35 device electric drive fully equivalent to the device 2 7 diation and tr ic . Pneumatic drive devices 21, 34 and 1 devices 2 7 , 3 5 diagnosis and tt recommended selectively check the raised positions of the movable portions 19, 33, for example depending on the a vector speed 1 , and , therefore , control selectively the aerodynamic behavior of the vehicle 1. Ino lt re , when arranged in their positions substantially complaints to fixed portions 18, 32 and do not compromise 1"aesthetic appearance of the car According to an unillustrated variant, bands 17, of coating comprise a plurality of portions furniture 19, 33 distributed along the fixed portions triangles 1 3 sides
