Embodiment Construction

[0021] figure 1 with 2 A bumper block arrangement is shown indicated by the general reference number 1 and is designed to be mounted between a top anchor seat (not shown) and a coil spring 2 which can be placed directly or indirectly on the chassis of a motor vehicle in the components. The bumper 1 is arranged around a shock absorber rod (not shown) extending on a substantially vertical axis 3 and a spring 2 is mounted around said rod.

[0022] The buffer block 1 basically comprises a top support cover 4 , a bottom support cover 5 , a bearing 6 arranged axially between said covers and a bottom holder 7 for the spring 2 .

[0023] The top cover 4 may consist of one piece made of plastic material, for example polyamide PA6.6, which may or may not be reinforced with glass fibres. The top cover plate 4 comprises a top radial portion 4a designed to be in contact with the top holder seat, a thin and small diameter annular inner axial skirt 4b and a thin and large diameter annular...

Abstract

The bump stop device, particularly for a motor vehicle, comprises a bearing 6 forming an axial stop, a bottom support cover 5 of the bearing and a bottom retainer 7 for a spring comprising at least one stiffening strut. The support cover 5 and / or the retainer 7 comprises at least one axial securing means 15 of the bottom retainer and of the bottom support cover, the said means being situated axially set back from a bottom end of the retainer.

Description

technical field [0001] The invention relates to bumper block arrangements, in particular for use in MacPherson strut suspensions of steered wheels on motor vehicles. Background technique [0002] Cushion blocks have traditionally been provided with top and bottom grooves between which the rolling elements and bottom and top retaining or support elements, such as cover plates, are provided, forming housings for the bottom and top grooves of the bearing respectively. A bumper is provided on top of the MacPherson strut between the suspension spring and a top element fixed to the vehicle body. Suspension springs are provided around the shock absorbers and their ends may be fixed to the body of the vehicle. The spring rests axially directly or indirectly on the bottom support cover of the bearing. [0003] The bumper thus makes it possible to transmit axial forces between the suspension springs and the vehicle body, while allowing relative angular movement between the rotatably...
