Embodiment Construction

[0064] Referring to Figures 4 and 5, it should be noted that the front structure, including the short subframe, is intended to be prepared off the production line and includes tie rods 11 (different positions of the links are shown in Figure 4) prior to coupling to the body. shown in ), an anti-roll bar (not shown), a torque link (not shown) and a suspension arm (or wishbone) 3 components. It should also be noted that the suspension arms are generally of the boomerang type, with one of the ends of each arm supporting the swivel part (point E) and intended for connection to the wheel, and having a front end for connection to the short subframe 1 Junction (point A) and rear junction (point B).

[0065] Assembling the different parts allows the surrounding movable elements - such as the suspension arm 3 (points A, B and E), the tie rod 11, the transverse transmission member 12 (the different positions of the transmission member are shown in Fig. Roll bar - move.

Abstract

A structure for a motor vehicle front end assembly includes a mini-cradle having mounted thereon a suspension arm for each wheel of the front end assembly. The suspension arm has the shape of a boomerang. The supporting end of the suspension arm is coupled to a wheel. A front articulation end (point A) and a rear articulation end of the arm are coupled to the mini-cradle. The mini-cradle has a body and two side rails that extend towards the vehicle front. The two side rails are coupled, via a coupling unit, to a side member of the vehicle in a zone located forward, relative to the longitudinal axis of the vehicle, of point A of the suspension arm. The coupling unit includes at least one hollow body allowing a through screwing unit to couple the rail with the side member.

Description

technical field [0001] The field of the invention is that of the automotive industry. More precisely, the invention relates to a subframe supporting the engine or rear of a motor vehicle. Background technique [0002] In a commonly used method, the engine subframe consists of two plates made of pressed sheet metal and joined together, for example by welding. [0003] One of the functions of this subframe is to withstand the forces generated by the engine torque during acceleration or deceleration of the vehicle. [0004] It should be noted that with reference to Figure 1, this subframe is fixed at the rear of the vehicle body. On the extension of the subframe there is a buffer 2 or "add-on", which is independent of the subframe and does not contact the subframe except in the event of a collision. Frame contact. [0005] This subframe is also coupled to a lower arm 3 supporting the wheel or carrying a wheel support 31 (schematically shown), an anti-roll bar 32 connecting ...
