Abstract: A motor vehicle rear axle is of the type having two longitudinal trailing arms. Each trailing arm has a stub-axle bracket at one rear end and, at an opposite front end, a substantially transverse axis of rotation defined by a first joint and a second joint which are intended to be connected to the vehicle body. A first and a second support element are located respectively in front of and behind a trailing arm on the side of its second joint. The free ends of these support elements, located in the longitudinal and vertical median plane of the rear axle, are kept at a longitudinally fixed distance by a connecting element.

Abstract: A suspension element of a vehicle includes a coil spring, and a bearing part provided with a main stop. The spring is mounted on the bearing part in such a manner that a first end of the spring comes to bear against the main stop. The bearing part includes a secondary stop placed in front of the main stop, against which secondary stop the first end of the spring bears during a method for assembling the suspension element. The secondary stop is capable of moving away under the effect of pressure exerted by the spring on the secondary stop during a stage of compressing the spring after the spring has pivoted about the spring's rotational axis during a stage involving straightening the spring, so that a second end of the spring is made to interact with a centering element, in order to come to bear against the main stop.

Abstract: A sliding device includes a sliding bearing, and a shaft which is rotatable and in slidable contact with the sliding bearing in presence of a lubricating oil. The sliding bearing has a surface hardness smaller than a surface hardness of the shaft. Additionally, the sliding bearing has a surface roughness Ra of not larger than 0.2 micrometer, and the shaft has a surface roughness of not larger than 0.05 micrometer.
