    摘要: The invention concerns a structure (1) comprising a structural element (4) including guide means (30, 32, 34) and protecting means (8) annexed to the structural element including at least one side-member (10) provided with a first engagement means (24) inside the side-member (10) and with a second engagement means (26) at one end (10b) of said side-member, each side-member (10) being positioned such that the end of one guide means is located between a first and a second engagement means, so that upon an impact on the structure, said end passes through the first engagement means (24). The invention is characterized in that at least a first engagement means (24) is provided with a closure (40) adapted to lock a guiding means (30, 32, 34) below a specific pressure, and adapted to yield above said pressure to allow the end of the guide means through the first engagement means.

    摘要: The invention relates to a motor vehicle steering axle comprising two longitudinal arms which are connected by means of a cross-member. According to the invention, each of the aforementioned longitudinal arms comprises: a front end which is connected to the body shell using an elastically-deformable articulation means, such as to enable wheel travel in relation to the vehicle shell in the event of longitudinal impacts on the wheel; and a rear end which is connected to a steering knuckle pin using at least one upper articulation means and one lower articulation means, said upper articulation means being elastically deformable in an essentially-longitudinal direction. The invention is characterised in that the steering axle comprises a connecting rod having a first end which is fixed to the steering knuckle pin and a second end which is articulated in relation to the above-mentioned cross-member close to the mid-plane thereof. In this way, the rotation of the steering knuckle pin around an essentially-longitudinal axis passing through the lower articulation means causes the complementary rotation of said steering knuckle pin around an essentially-vertical axis.

    摘要: The invention relates to an upper mounting device (20) for connection of a suspension shock absorber (10) on a front wheel to the chassis (18) of a motor vehicle. The shock absorber (10) comprises a body (12), a shaft (14), moving by translation within said body and a spiral spring (16), mounted concentrically around the shaft. The device comprises a single cup (22) fixed to the free end (15) of the shaft with the concave side thereof facing the edge of said end, an elastomeric mass (24) with a support (26) and means for connection (28) of the spring (16) to said elastomeric mass (24). The elastomeric mass (24) is fixed to said cup (22) and to the vehicle chassis (18) such as to guarantee the damping of the vehicle movements essentially in the axis of the shaft (23).

    摘要: The invention concerns a motor vehicle wheel support arrangement wherein a hub (2) rotatably mounted on a stub axle (3), supports the wheel (1) and a brake disc (6) associated with said wheel (1), and wherein the stub axle (3) includes a spherical element (22) rotatable in a ball-joint housing (21) integral with a suspension arm (8), such that the stub axle (3) and the suspension arm (8) are connected by a ball-joint connection (20). The invention is characterized in that the ball-joint housing (21) comprises at least one cage (31) adapted to receive the spherical element (22), and a support element (33) projecting from the cage (31) adapted to be urged into contact with the brake disc (6) when the motor vehicle is subjected to an impact.
