Embodiment Construction

[0030] figure 1 with 2 A suspension bearing arrangement 10 according to the invention is shown, suitable for mounting to a strut 1 also according to the invention.

[0031] Pillar 1, partly in figure 1 Shown in, belongs to the motor vehicle suspension system. The struts 1 support the axles and wheels of the vehicle, not shown for sake of clarity. When the wheels of the vehicle are at rest on a flat road, the strut 1 extends along a main axis X1 which is in a substantially vertical direction. The strut 1 includes a suspension spring 3 , a suspension bearing arrangement 10 and a shock absorber piston including a piston body and a shock absorber rod 2 . Rod 2 and spring 3 are in figure 1 The middle part is shown, while the piston body is not shown for the sake of brevity.

[0032] In the following, for easier spatial identification of the device 10 , a bottom side Ci is defined, on which the road and the wheels of the vehicle are located, and a top side Cs opposite the b...

Abstract

The present invention relates to a method for manufacturing a suspension bearing device, comprising at least one rolling bearing, a bottom cup and a top cup made of plastic, each in contact with the rolling bearing, and at least one seal suitable for protecting the rolling bearing from ingress of water or of polluting particles. The method is characterized in that it comprises at least one step of positioning a seal made of thermosetting elastomer on a supporting element made of plastic between the bottom cup and the top cup and, for the or each seal made of thermosetting elastomer, a step of curing this seal on its supporting element. The invention also relates to a suspension bearing device and a strut of a motor vehicle.

Description

technical field [0001] The present invention relates to a method of manufacturing a suspension bearing unit, in particular of the MacPherson type (MacPherson Suspension Bearing or MSBU). The invention also relates to a suspension bearing arrangement. The invention also relates to a motor vehicle strut comprising a shock absorber and a said suspension bearing arrangement. The field of the invention is that of suspension systems, in particular for motor vehicles. Background technique [0002] As is known, a motor vehicle suspension system includes struts that support the vehicle's axles and wheels. Opposite the ground and the wheels, the suspension bearings are disposed on top of the struts, between the suspension springs and the top member fastened to the vehicle body. The spring is disposed around the shock absorber piston rod, the end of which is fastenable to the vehicle body. [0003] The suspension bearing includes a rolling bearing, a bottom cup, a top cup, and at l...
