Embodiment Construction

[0027] In the remainder of the specification, elements having the same structure or similar functions will be denoted by the same reference numerals.

[0028] In the remainder of the description, the following orientations will be taken by way of non-limiting example: longitudinal orientation leading from rear to front along the direction of travel of the vehicle; transverse orientation; and bottom to top leading in a direction perpendicular to the road vertical orientation.

[0029] The terms "inner" and "outer" will be used according to the proximity of an element to the central longitudinal axis of the vehicle.

[0030] The terms “inner” and “outer” will be used according to the location of the element relative to the volume of the tank 12 .

[0031] figure 1 Represents a wheeled rear axle assembly 10 of a motor vehicle (not shown) incorporating a fuel tank 12 intended to supply the vehicle's internal combustion engine (not shown). The engine is here an internal combusti...

Abstract

The invention relates to a wheeled rear axle assembly (10) for a motor vehicle comprising: a central connection support (14) that comprises at least a first front crossmember (16) and a second crossmember (18) arranged behind the first front crossmember (16); at least two articulations (42) each comprising at least two lower suspension arms (44, 52), each of which connects an associated steering knuckle (20) with one side of the connection support (14), each suspension arm (44, 52, 60) being mounted pivotably on the first and second crossmembers (16, 18) of the connection support (14); characterised in that the connection support (14) comprises at least one tank (12) delimited by a rigid outer wall, the first and second crossmembers (16, 18) being rigidly connected to each other via the wall of the tank (12).

Description

technical field [0001] The invention relates to a wheeled rear axle assembly of a motor vehicle, comprising: [0002] - a central connecting support intended to be fastened underneath the body of the vehicle and comprising at least a first front cross member and a second cross member arranged longitudinally behind the first front cross member ; [0003] - at least two articulations each comprising at least two lower suspension arms, each of which connects an associated steering knuckle to one side of the connection support, each A suspension arm is pivotally mounted on the first and second beams of the connecting support about a generally longitudinal axis. Background technique [0004] Vehicles equipped with this type of rear axle are known. This suspension arrangement is commonly known by the name multi-arm suspension. [0005] A central support is usually formed by a carrier bracket, on which the two suspension arms are articulated. This is the rigid structure that r...
