A method for manufacturing a central underbody portion of a structural body of a motor vehicle to delimit a bottom of a passenger compartment of the vehicle. The method includes assembling a floor of the central underbody portion, attaching an integral central profile to the floor, arranged in a longitudinal direction of the vehicle and having a length dependent on a length of the central underbody portion in the longitudinal direction, and assembling at least one end piece forming an extension of the central profile. The end piece has an interface providing a connection and a function of absorbing and transmitting forces with a structural portion of the body that is separate from the central underbody portion and/or with the floor. The attaching includes adapting the length of the central profile as a function of the length of the central underbody portion in the longitudinal direction.

Method for manufacturing a central underbody portion including a multi-part tunnel

A range includes at least two different motor vehicles with a structural body having a central underbody part delimiting a lower part of a cab. The central underbody part of the first vehicle receives two seats. The central underbody part of the second vehicle receives four seats. Each central underbody part includes first interface elements allowing mounting thereon of components associated with the function of an internal combustion drive engine mounted on a rear structural part of the structural body which is firmly attached to the central underbody part. Each central underbody part also includes second interface elements allowing mounting thereon of components associated with the function of an electric drive motor to be mounted on the rear structural part. A rear edge of the central underbody part of each vehicle is equipped with a same interface element for connection to the rear structural part of the structural body.

A body structure of a motor vehicle includes two substantially parallel longitudinal reinforcing side members, a body side superstructure connected to the side members, rising above the side members and defining, on either side of the vehicle, two wheel arch housing portions of the vehicle. The two wheel arch housing portions are connected by a floor portion of the vehicle, offset vertically relative to the side members and positioned above the side members. The structure also includes at least one rear shock absorber attachment cup at each wheel arch housing portion. The at least one rear shock absorber attachment cup is assembled to the side superstructure, and assembled to a side member by a raising part connecting the cup and only a portion of the side member, having a width, measured in a longitudinal direction of the vehicle, substantially equal to that of the cup.

The invention relates to a device for attaching an end of a cross-member of a driver's compartment of a motor vehicle to the assembled shell, which includes an attachment element provided with a first surface, for receiving the cross-member of a driver's compartment, and with a second surface opposite the first surface. Said device comprises first and second reinforcements extending from the second surface and each including: a base connected to the attachment element and to be attached to a portion of the vehicle, two side walls extending from the base and connected to the attachment element.

An arrangement for a motor vehicle including a dividing wall disposed between an engine compartment and a passenger compartment of the vehicle, a water container to collect the water running over the windscreen of the vehicle, and at least one collector to collect an overflow of water contained in the water container. The at least one collector is made up of a component forming an integral part of the dividing wall.

A motor vehicle structure includes two left and right bell-shaped suspension element supports arranged inside a front compartment close to a bulkhead of the vehicle. The suspension element supports are respectively adjacent to side walls of the front compartment. Each of the suspension element supports includes an internal face opposite the side wall. The structure also includes left and right spacers that extend respectively between the left and right suspension element supports and the rigid cross member, in a substantially longitudinal direction. The spacers are respectively anchored to the internal faces of the two suspension element supports. The spacers each have a skirt-shaped edge that can be applied to the suspension element supports, and a folded edge extending between a free end and an opposing attachment end to be joined to the cross member. The spacers include a central portion joining the folded edge and the skirt-shaped edge together.

A motor vehicle rear structure includes an underframe component for supporting a motor vehicle floor, an axle component including a central part and two lateral parts that define, with the central part, a space to accommodate a component of the vehicle, and a pivot member including a first pivot element and a second pivot element which are able to pivot relative to one another. The rear structure is arranged such that the first and second pivot elements pivot relative to one another about an axis that is substantially horizontal and substantially perpendicular to a direction of travel of the vehicle in a frame of reference of the motor vehicle, when the first and second pivot elements are thus fixed to the central part of the axle component and to the underframe component of the motor vehicle, respectively.

Rear structure of a motor vehicle

A motor vehicle rear structure includes an underframe component to support a motor vehicle floor and in which a tunnel is formed, an axle component including a central part and two lateral parts that define a space to accommodate a component of the vehicle, an articulation device including a first articulation element and a second articulation element which are able to pivot relative to one another, and at least one front reinforcing element fixed to the second articulation element and to the tunnel. The rear structure is arranged in such a way that said at least one front reinforcing element allows at least some of a load in the direction of travel of the motor vehicle derived from the axle component to be transmitted to the tunnel.

A motor vehicle chassis comprises two side members that are at least partially hollow and have an approximately rectangular cross-section, and two identical reinforcement parts each capable of engaging with a side member to support a power train in an engine compartment of the motor vehicle. Each reinforcement part comprises a substantially parallelepipedic stamped metal sheet open on one face. Each reinforcement part is disposed entirely inside one of the side members and comprises two orifices in a first face and two orifices in a second face, which is separate from and orthogonal to the first face. The four orifices are tapped so as to define four identical nuts.

A chassis of a motor vehicle optimized for absorbing a frontal impact. The chassis includes a firewall separating a passenger compartment of the vehicle from a front portion of the chassis configured to hold an engine, and a mechanism for absorbing a frontal impact including two side rails mounted on at least the front portion of the chassis and arranged on either side of the chassis, each side rail including a front portion and a rear portion assembled to overlap at least partially. The side rails are arranged such that an overlap area is below the plane of the firewall, and the rear portion of the side rail includes a material which is less compressible than the front portion of the side rail.

A chassis of a motor vehicle including a mechanism for absorbing a frontal impact including two side rails mounted on a front portion of the chassis and arranged on either side of the chassis, a front crossmember mounted under a floor of a passenger compartment of the vehicle in contact with a transmission tunnel arranged on a central axis and extending from the front crossmember towards a rear portion of the chassis. Each side rail includes one end mounted to engage with the front crossmember.
