Problems solved by technology

This leads in particular to the resultant direction of the forces exerted by the helical suspension springs being inconsistent with respect to the axis of the spring: in particular, the resultant force is not generally directed exactly along the axis of the spring, which causes parasitic forces to be applied to on the vehicle and cause, for example, the rear wheels of the vehicle to skid

Embodiment Construction

[0016] figure 1 The end portion of the suspension spring 1 and the end coil 2 are schematically shown, together with a sheath 3 in a suitable housing 4 into which at least a part of the end coil 2 is inserted.

[0017] In the suspension arrangement according to the invention, the angular position of the suspension spring 1 is indexed relative to the centering sleeve 7 by suitable means. These means include, on the one hand, a first set of means 6 capable of indexing the angular position of the sheath 3 relative to the centering sleeve 7 and, on the other hand, capable of indexing the angular position of the suspension spring 1 relative to the sheath 3. Degree of the second set of devices 8.

[0018] In a preferred embodiment of the invention, suitable means 6 capable of indexing and reproducible angular positioning of the angular position of the sheath 3 relative to the centering sleeve cover 7 comprise at least one male part 61 located in the on the sleeve 3 (or on the cen...

Abstract

The invention relates to a suspension spring of a motor vehicle comprising a suspension spring (1), a sheathing (3) to be placed on a portion of at least the end coil (2) of the suspension spring (1), and a centering cup (7) on which said sheathed end of the suspension spring (1) is placed, appropriate means (6) for indexing the angular position of the sheath (3) with regard to the centering cup (7), and appropriate means (8) for indexing the angular position of the suspension spring (1) with regard to the sheath (3).

Description

technical field [0001] The present invention relates to sprung suspension systems for motor vehicles, and in particular to a sheathing arrangement for such springs. Background technique [0002] In fact, the end coils of such springs, which are usually placed on the centering sleeve, are exposed to water and / or accumulated debris in the vicinity of contact with said sleeve. Furthermore, the friction of the end rings with the centering sleeve can cause disturbing noises: it is therefore known to wrap the end rings of such springs around at least the part that is in contact with the centering sleeve together, this both protects it from erosion and limits noise caused by friction or vibration. [0003] Thus, document FR 2 840 966 proposes a sheath, for example for the end coil portion of a helical suspension spring, whose openings on the inner periphery make it possible to protect the end of the spring from standing water and accumulated debris. The sheath proposed in docume...
