The document DE 100 23 781 A1 discloses a mounting device for a vibratable component having a holder and a damping element arranged thereon. The bracket has holes to accommodate screws can, with which the bracket is screwed to a vehicle floor. The damping element is cone-shaped. In the damping element, a bore for receiving a retaining clip for attachment to the exhaust system is arranged centrally.

Furthermore, suspension devices for exhaust systems are known from the prior art. Such a suspension device is used, for example, in the document EP 0 839 680 B1 described. The suspension device comprises an outer ring and an inner ring, wherein the outer ring crosses the inner ring at 90 °. The inner ring and the outer ring are connected to bent end portions, each having a screw. By means of these screws, the suspension device can be attached to the vehicle body and the exhaust system.

With the devices described above, it is problematic to meet today's requirements for such a bearing device just in terms of the vehicle acoustics and the rigidity of the bearing device in case of load.

It is an object of the present invention to provide a bearing device that meets today's requirements for such a device at low cost production, and in particular in the case of load has increased rigidity.

This object is achieved with a bearing device of the type described, in which the damping body has at least one damping arm which extends between the fastening devices in such a way that it has a predetermined distance to a counterpart bearing section of at least one opposing bearing body with an abutment section in the unloaded state of the damping body, wherein the at least one damping arm arches to achieve a progressive damping characteristic as a result of a compressive load and initially deforms freely under magnification of the curvature and then applies with the contact portion to the opposite plant section.

With the bearing device according to the invention, on the one hand, it is achieved that the bearing device has a relatively low rigidity in the static load case. A low stiffness in the static load case is necessary in order to meet today's very high demands on the vehicle acoustics.

On the other hand, when the exhaust system is excited or set in motion during operation of the vehicle due to bumps and bumps in the road surface, after initial free deformation with increasing pressure load, the at least one damping arm engages the counter abutment portion of a counter abutment body, whereby the rigidity of the bearing device relative greatly increased and progressively increases. With such a progressively stiffened bearing device, movements or vibrations of the exhaust system relative to the vehicle can be effectively limited.

According to a preferred embodiment it can be provided that the damping arm already in its basic form or even under pressure to the at least one counter-investment body bulges out and extends between the fasteners such that it with the vertex of the curvature comprehensive investment section in the unloaded state the damping body has a predetermined distance to a counter-bearing portion of the counter-abutment body. As stated above, the at least one damping arm initially deforms freely to achieve a progressive damping characteristic as a result of a compressive load, increasing the curvature, and then abuts with the abutment portion against the countersection section. In other words, the damping arm in this embodiment of the invention already in the unloaded state, a curvature which increases in the loaded state with pressure and comes into abutment with a mating abutment portion of the opposing abutment body.

According to the invention it can be provided that the damping body of the bearing device has at least two, preferably curved, damping arms. Preferably, the at least two damping arms face each other and are preferably curved in the direction of the respective other Dämpfungsarms.

In the unloaded state of the damping body, a predetermined distance between the abutment portion and the mating abutment portion is given. As a result of a compressive load, the damping arms deform to achieve a progressive damping characteristic such that the curvature of the two damping body in the direction of the respective other damping body increases and the abutment portion and the mating abutment abut each other. In other words, the rigidity of the bearing device increases in the direction of the vehicle vertical axis, as soon as the two damping arms overcome the predetermined distance between them and the abutment portion of the one damping arm with the mating abutment portion of the respective other damping arm comes into abutment.

Constructively, the bearing device is designed such that the at least one attachment means for vehicle-mounted mounting of the bearing device and the at least one attachment means for Abgasanlagenseitigen attachment of the bearing device are provided at opposite end portions of the at least one damping arm.

In other words, the rigidity also increases in the case of tensile loads, since the textile insert has a very high rigidity when stretched.

According to a preferred embodiment, the two damping bodies are curved in opposite directions. At the same time, the damping bodies are each arched in the direction of a counter bearing body. In other words, the bearing device according to the invention can also be designed such that the two curved damping arms do not move toward each other under a compressive load under an increase in the curvature, but increase the curvature in opposite directions. In this case, the damping arms approach under pressure load with their curvature to a counter-investment body until they rest against a mating abutment portion of the opposing investment body. If the damping arms with their curvature on the counter-investment body, the rigidity of the bearing device increases progressively.

The counter-abutment body may also be arranged between the at least two opposing damping arms, wherein the two opposing damping arms are arched towards the counter-abutment body according to a further preferred embodiment of the present invention.

The damping body has, according to a preferred embodiment of the invention, at least four damping arms, two of which are opposed in pairs. Overall, results in this embodiment in plan view, a cross-like arrangement.

In the unloaded state, the four damping arms preferably each have a predetermined distance from the at least one mating abutment section. As a result of a compressive load, the at least four damping arms initially deform freely and attach themselves to the opposing abutment section of the at least one opposing abutment body, increasing their respective curvature.

Structurally, the bearing device according to this embodiment is designed such that the vehicle-side fastening device has at least one receiving opening which receives the damping body and the exhaust-gas-side fastening device. In this case, the exhaust gas-side fastening device is preferably formed bolt-shaped. Alternatively, instead of a bolt-shaped fastening device, a plate-shaped element can be provided, which is in communication with the damping body and can transmit a force in the direction of the vehicle longitudinal axis to the bearing device.

According to the invention, the at least one counter-abutment body is provided on the at least one receiving opening.

According to a preferred embodiment, the opposing abutment body arranged between the at least two damping arms is the exhaust-gas-side fastening device. In this case, the fastening device preferably has a Counter abutment section on which the contact portion of the damping arms can create as a result of a compressive load.
