Problems solved by technology

Furthermore, since the sole function of the profile is to stiffen the longitudinal beams, some skilled in the art consider it risky to reduce the area of ​​the profile towards the wheels, thus changing the wheel tunnel without affecting the body structure

Embodiment Construction

[0025] figure 1 is a view of a motor vehicle 2 comprising an underbody rail 4 according to the invention. A side member 4 (one of which is visible in the figure) extends longitudinally between a front 6 and a rear 8 of the vehicle, each of which delimits a wheel tunnel 10 . Each of these underbody rails 4 comprises an inner underbody rail 12 according to the invention. The inner underbody rail 12 is commonly referred to as a "front foot", and this portion of the rail 4 is configured to support the load of the vehicle door.

[0026] figure 2 is a side view of the right underbody rail 4 comprising an underbody inner rail 12 or an underbody inner "front foot" 12 according to the invention. The underbody rail 4 of the vehicle comprises a U-shaped elongated inner profile 14 (on the left in the figure) assembled to an inner front foot 12 (on the left in the figure), which is itself assembled to the front part 6 of the vehicle (on the right in the figure) . The front leg 12 com...

Abstract

The invention relates to an internal sill (12) of a motor vehicle, forming a hollow U-shaped cross-section body and having: a first portion (16) intended to extend horizontally; and a second portion (18) forming an elbow with the first portion (16) and being intended to extend upwards, said portion comprising a front face (20) opposite the first portion (16) and intended to define a vehicle wheel passage, said face comprising a rebate (26) for a joint with another hollow body; the joint rebate (26) being formed by an elbow section component (28), said component being connected on the front surface (20) of the second portion (18). The invention also relates to a motor vehicle, comprising such an internal shell sill (12).

Description

technical field [0001] The invention relates to the field of construction of motor vehicles. More specifically, the invention relates to the field of manufacture of underbody bodies. Background technique [0002] Mounting the wheels of a motor vehicle at the front and rear of the vehicle falls within the scope of constructing a vehicle body, which should be configured to create a minimum distance between the wheels and the vehicle body. The volume of the wheel tunnel should integrate the axle play of the wheels connected to the vehicle suspension, which also generally should integrate the increase in wheel size, for example equipped with chains for driving on snowy ground. Additionally, current trends in the automotive industry include an increase in wheel size. The increase in wheel size has an impact on all types of vehicles, especially on the body structure that forms the wheel tunnel. [0003] Patent document FR 2905111 A1 discloses an underbody rail of a motor vehicl...
