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.
Claims12
A suspension element of a vehicle, comprising a coil spring, and a bearing part provided with a main stop, the spring being mounted on the bearing part in such a manner that a first end of the spring contacts the main stop after assembly, the first end of the spring being a surface facing in an axial direction of a coiled wire rod of the spring,
- wherein the bearing part comprises a secondary stop placed between the main stop and the first end of the spring, against which secondary stop the first end of the spring contacts while assembling the suspension element, the secondary stop being 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 a rotational axis of the spring during a stage involving straightening the spring, so that a second end of the spring is mounted to a centering element, in order for the first end of the spring to contact the main stop, and
- the main stop and the secondary stop extend from a bottom of the bearing part in the same direction.
A method for assembling a suspension element of a vehicle, the suspension element comprising a coil spring, and a bearing part provided with a main stop, the spring being mounted on the bearing part in such a manner that a first end of the spring contacts the main stop after assembly, the first end of the spring being a surface facing in an axial direction of a coiled wire rod of the spring, wherein the bearing part comprises a secondary stop placed between the main stop and the first end of the spring, against which secondary stop the first end of the spring contacts while assembling the suspension element, the secondary stop being 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 a rotational axis of the spring during a stage involving straightening the spring, so that a second end of the spring is mounted to a centering element, in order for the first end of the spring to contact the main stop after assembly, and the main stop and the secondary stop extend from a bottom of the bearing part in a same direction, wherein the method for assembling the suspension element comprises:
- a first step of positioning the spring on the bearing part in such a manner that the first end of the spring contacts the secondary stop,
- a second step involving straightening the spring while keeping the spring in contact with the bearing part, in order to mount the centering element to the second end of the spring,
- if the spring has pivoted during the second step involving straightening the spring, a stage in which the secondary stop is flattened by the spring to allow the first end of the spring contact the main stop,
- a third step of compressing the assembly.
