AI Technical Summary

Problems solved by technology

However, in case of significant vibrations, unfavorable noise can be generated
In this case, the axial damping effect of the ring is not entirely satisfactory due to its small thickness
Additionally, the suspension springs may interfere radially with the rigid body of the lower cup

Embodiment Construction

[0036] figure 1 and 2 A suspension bearing arrangement 10 according to the invention and its constituent elements are shown. The device 10 is configured to be equipped with a vehicle suspension system figure 1 Partially shown strut 1.

[0037] The struts 1 support the axles and wheels of the vehicle, not shown for simplicity. The strut 1 extends along a central axis X1 which is arranged substantially in a vertical direction when the wheel is placed on flat ground. The strut 1 includes a damping rod 2 , a suspension spring 3 and a suspension bearing device 10 . Rod 2 and spring 3 are partially and schematically shown in figure 1 superior. The strut 1 also includes a piston body and a buffer, which are not shown for simplicity. The damping rod 2 and the piston body form the damping piston belonging to the strut 1 .

[0038] The device 10 has a general shape that rotates about the axis X1. The device 10 includes a rolling bearing 20 , a lower cup 30 and an upper cup 40 ....

Abstract

The invention concerns a suspension bearing device, comprising a bearing, a lower cup (30) and an upper cup centered on a central axis, the lower cup (30) having a body (50) including a tubular axial portion (51) and an annular outward radial portion (52), the lower cup (30) being provided with at least one seal (80, 90) disposed in sealing contact with the upper cup (40), characterized in that the lower cup (30) is provided with a damper pad (70) having a cambered shape delimited by: an inner portion (71) which is connected to the seal (80, 90) through the radial portion (52) of the body (50) ; and a convex outer portion (72) for bearing a suspension spring (3). The invention also concerns a motor vehicle equipped with such a suspension bearing device and a method for manufacturing such a suspension bearing device.

Description

technical field [0001] The present invention relates to suspension bearing arrangements, in particular of the MacPherson type ("MacPherson Suspension bearing" or MSBU). The invention also relates to a motor vehicle equipped with such a suspension bearing arrangement. The invention also relates to a method of manufacturing such a suspension bearing arrangement. The field of the invention is suspension systems, in particular suspension systems for motor vehicles. Background technique [0002] It is known that the suspension system comprises struts supporting the axles and wheels of the vehicle. The suspension bearing arrangement is provided on top of the strut, opposite the wheel and underside, between the suspension spring and the upper member securing the body of the vehicle. The spring is arranged around the damper piston rod, the end of which is fixable to the vehicle body. [0003] WO-A-2011 / 012484 discloses an example of a suspension bearing device comprising a rolli...
