Definitions

  • the present invention relates to a pneumatic damping bearing, in particular engine mount for motor vehicles, with a suspension spring made of an elastomeric material which supports a bearing core and limits a working chamber, wherein the working chamber with a gas, in particular air, is filled and via a nozzle opening with the environment or connected to another chamber.
  • Such a pneumatic damping bearing is known from DE-A 10 2004 008 401.
  • the suspension spring has a wide, flat, cross-sectional shape in order to achieve a small volume of the working chamber with the largest possible pump cross-section.
  • a pneumatic spring bearing is known, the working chamber is limited on the one hand by the suspension spring and on the other hand by a damper plate.
  • a foam layer is applied over the entire surface and glued to it. The foam layer serves to decouple spurious oscillations with small amplitudes.
  • a nozzle channel is provided, which connects the working chamber with the environment.
  • the invention has for its object to propose a pneumatic damping bearing which avoids the problems described above.
  • a progression element is provided of an elastomeric material, and that the progression element of the suspension spring is arranged opposite and limits the working chamber with this.
  • the required force-displacement curve is generated by the suspension spring and the progression element. If the suspension spring operates around the operating point, the working chamber is compressed between the progression element and the suspension spring. Since the progression element is sufficiently volume-stable due to the elastomeric material used, attenuation occurs during the displacement of air via the nozzle opening provided in the progression element. With increasing, quasi-static loads, the working chamber volume is reduced until it is completely closed and the underside of the suspension spring rests completely against the top of the progression element. Upon further loading, the progression element is elastically deformed. As the load increases further, the quasi-static stiffness increases until finally the maximum travel is achieved.
  • the progression element advantageously has at least one air chamber on a side facing away from the working chamber. This will result in a increased compliance of the Progressionsettis achieved in its deformation.
  • the air chamber can advantageously have groove-shaped recesses, which are formed in the progression element.
  • the groove-shaped recesses may be formed, for example, rotationally symmetrical.
  • the nozzle opening is introduced into the progression element.
  • suspension spring and the progression element are received in a pot-shaped housing.
  • Ventilation bores are advantageously introduced into the housing in the area of the air chamber in order to allow the displaced air to escape.
  • the air chamber is connected via a nozzle opening with the working chamber.
  • the nozzle opening acts as a pressure relief valve at high pressures and pressures.
  • the progression element is designed as a one-piece vulcanization part.
  • the progression element has a molded fastening flange, in particular for fastening to the housing.
  • the nozzle opening can be introduced in the attachment area.
  • the progression element is vulcanized or glued in the housing.
  • the invention will be explained in more detail by means of exemplary embodiments, which are shown schematically in the drawing. Hereby show:
  • FIG. 1 shows a vertical section through a first embodiment of a bearing according to the invention
  • FIG. 2 shows a vertical section through a second embodiment of a bearing according to the invention
  • FIG. 3 shows a vertical section through a third embodiment of a bearing according to the invention.
  • FIG. 4 shows a vertical section through a fourth embodiment of a bearing according to the invention
  • Fig. 5 is a force-displacement characteristic of the bearing according to the invention.
  • the pneumatically damping bearing 10 shown in FIG. 1 is used to support a motor, not shown, of a motor vehicle.
  • the bearing 10 has a suspension spring 12 made of an elastomeric material, in particular rubber on.
  • a bearing core 13 is vulcanized, having a vertically projecting pin 14 for attachment to the engine.
  • the suspension spring 12 is supported on its outer periphery of a cup-shaped housing 15, which has a radially projecting flange 16 for fixing to the vehicle body.
  • the housing 15, which is presently rotationally symmetrical, but in principle may also have a different cross-sectional shape, has an opening 20 in the center.
  • a progression element 17 made of an elastomeric material is accommodated, which has a fastening flange 19.
  • a fastening flange 19 is provided on this, which is knotted into the housing opening 20.
  • the progression element 17 has an upper side 17a which, with the inner side 12a of the suspension spring 12 arranged at a distance therefrom, delimits a working chamber 11.
  • the air-filled working chamber 11 is connected via a nozzle opening 18 which penetrates the mounting flange 19, with the environment.
  • the progression element 17 has on its side facing away from the working chamber 11 underside 17b an air chamber 21, which is formed by groove-shaped recesses 22. By the air chamber 21, the compliance of the progression element 17 is increased at a pressurization.
  • FIGS. 2 to 4 show further embodiments, for the description of which the already introduced reference numbers are used for identical or functionally identical parts.
  • the illustrated in Fig. 2 pneumatic damping bearing 10 has a progression element 17 which is accommodated in the housing 15.
  • the progression element 17 is fixed to the housing 15 by gluing.
  • On the bottom 15 a of the housing 15 a plurality of openings 23 a, 23 b are provided, which connect the air chamber 21 of the progression element 17 with the environment. As a result, a particularly high compliance of the progression element 17 is achieved.
  • the progression element 17 has an air chamber 21, which is connected to the working chamber 11 via a nozzle opening 24.
  • the nozzle opening 24 acts as a pressure relief valve at high pressures or pressures.
  • the progression element 17 has a central nozzle opening 18 which communicates with the housing opening 20.
  • the nozzle opening is designed as a slotted membrane.
