Embodiment Construction

[0033] Commonly described below Figure 1 to Figure 5 . They show a spring bearing assembly 2 according to the invention comprising a spring 3 and a spring seat 4 to which an end 5 of the spring 3 is connected. The spring seat 4 receives the end 5 of the spring 3 and can thus also be referred to as a spring receiving device or spring receiving member. The spring 3 is made of a suitable spring material, more particularly of hardened spring steel, although other types of elastic material, such as fibre-reinforced plastic, could also be used therein. The spring seat 4 consists of an elastic material, more specifically plastic or rubber containing an elastomer.

[0034] The spring 3 is in the form of a helical spring comprising spring wires around the center line of the spring. At its end opposite to the first end 5, the helical spring 3 comprises a second end 6 which is receivable in a second spring seat or spring receiving element (not shown). The shown spring assembly 2 can...

Abstract

The invention relates to a spring assembly comprising a spring (3) with a coating (7), a spring seat (4) made of plastic and an adhesive layer (8), the spring (3) and the spring seat (4) They are bonded to each other by an adhesive layer, wherein the hardness of the adhesive layer (8) is less than that of the coating (7). The invention also relates to a process for manufacturing such a spring assembly (2).

Description

technical field [0001] The invention relates to a spring assembly with a spring, in particular for a chassis of a motor vehicle. Such spring assemblies typically include spring seats that receive the ends of the spring coils. Background technique [0002] A spring bearing assembly is known from DE 10 2011 002 065 A1. The bearing assembly includes an annular spring washer made of elastomer in which part of the spring winding of the spring is housed. An adhesive is introduced between the spring and the spring washer, so that the connection between the spring washer and the spring constitutes a glued connection. The adhesive hardens at room temperature. [0003] EP1165331B1 proposes an assembly of bearings with helical springs and spring struts. A spring strut for a motor vehicle includes a shock absorber connected at its upper end to the chassis of the vehicle and at its lower end to the wheel axle, and also includes a coil spring. The lower end of the coil spring is conn...
