Definitions
- Elastic bearing in particular motor bearings for motor vehicles
- the invention relates to an elastic bearing, in particular engine mounts for motor vehicles, with at least two spring elements connected in parallel with one another, with force introduction means that connect a vibration source to the at least two spring elements, a switchable coupling device being provided with which the force introduction means can be connected to at least one spring element is.
- Such an elastic bearing is known from DE-A 41 28761 .4.
- two spring elements are connected in parallel, each having a spring body made of an elastomeric material.
- One of the spring bodies is designed as a hollow cylinder and accommodates the second spring body in its interior.
- the internal spring element has force introduction means which can be switched by means of a coupling device.
- the coupling device has a coupling element fixed to the spring element, which can be non-positively connected to a second coupling element.
- the switching movement is achieved by a hydraulically actuated membrane.
- In the known engine mount there are relatively large switching paths and relatively high peeling forces for engaging the coupling elements necessary. Furthermore, there is no axial decoupling of the second spring element in the uncoupled state.
- Another engine mount is known from DE-A 41 39046, in which the spring element is designed as a hollow cylinder made of elastomeric material, which is arranged on the one hand between an engine-side mounting plate and on the other hand between a body-side mounting plate.
- a hydraulically damping bearing is provided below the body-side bearing plate, which is designed as a two-chamber bearing. While the hollow cylindrical spring block provides a high level of structure-borne sound insulation, the hydraulic bearing connected in parallel serves to dampen low-frequency vibrations. Switchability of the stiffness is not provided for in this engine mount.
- the invention has for its object to propose an engine mount in which the coupling device has only small switching paths and only low switching forces are required and in which there is an axial decoupling of the non-acting spring element in the uncoupled state.
- the coupling device has a first coupling element and a second coupling element which can be connected by means of an actuator, that the second coupling element can be connected in a coupled state to the force introduction means of the second spring element and that the second coupling element is designed as a rotating body which is pivotally mounted in the coupled state.
- the bearing according to the invention can in principle be realized with different types of spring elements.
- at least two conventional spring elements with spring bodies made of elastomeric material or a combination of a conventional spring element with such a spring body made of elastomeric material and a hydraulically damping bearing can be used.
- the spring body of the spring element can be designed as a hollow cylinder.
- the spring element can have at least two spring bodies arranged opposite one another, each of which is wedge-shaped.
- the spring element extends primarily in one spatial direction.
- different stiffnesses can be set in the transverse and longitudinal directions.
- the force-displacement characteristic is easily adjustable.
- the coupling device according to the invention is characterized by short activation paths and low switching forces.
- the second coupling element of the coupling device used ensures an axial decoupling of the second spring element in the uncoupled state.
- the delivery of the first coupling element to the second coupling element brings about a non-positive connection between the second coupling element and the force introduction means.
- the second coupling element is designed as a rotating body which is pivotally mounted in the uncoupled state, the second spring element can perform a tilting movement under radial loads. This leads, in particular in the case of a spring element designed as a hydraulically damping bearing, to the fact that in the case of radial loads essentially no hydraulic effects occur. This reduces the radial rigidity in the uncoupled state.
- the second coupling element is advantageously designed as a spherical body which is received in a bearing socket.
- the second coupling element has a receptacle for the second force introduction element, the opening cross section of which can be changed for the non-positive fixing of the second force introduction element.
- the second coupling element has at least one slot which is closed by the first coupling element in the coupled state.
- the coupling element is advantageously made of brass or another bearing material.
- the first coupling element advantageously has a receiving opening which is adapted to the outer contour of the second coupling element.
- the second coupling element In the coupled state, the second coupling element then lies at least partially in this receiving opening.
- the clamping mechanism can alternatively be designed with a clamp, in which an actuator changes the diameter of the clamp via an adjusting screw. Due to a conical seat of the bearing shells in the clamp, the radial force of the set screw can be axially Force be diverted to the bearing shells. The angle of the conical seat enables a force transmission.
- the actuator can be designed as an electrical, piezoelectric, pneumatic or hydraulic actuator. It is advantageous in all of the embodiment variants that only small switching paths and switching forces occur due to the design of the coupling device according to the invention.
- a first spring element has a spring body made of elastomeric material and a second spring element is designed as a hydraulically damping bearing.
- the hydraulically damping bearing is expediently designed such that it can be activated.
- the spring body is designed as a hollow cylinder and accommodates the hydraulically damping bearing in its inner opening.
- the elastic bearing has only small dimensions.
- the at least two spring elements can each have a spring body made of an elastomeric material.
- at least one of the two spring elements can be activated by the coupling device according to the invention to change the rigidity.
- the first spring element has a bearing plate, on which a bearing socket is designed for pivotally accommodating the second coupling element. This will achieved an articulated arrangement of the force introduction element of the hydraulically damping bearing in the uncoupled state.
- the bearing plate is provided with a hollow cylindrical extension in which the first coupling element is guided.
- the second force introduction means is designed as a round bolt which projects from a bearing core of the second spring element.
- the second coupling element can advantageously be designed as a spherical body which has a bore running in the axial direction for receiving the second force introduction means.
- the spherical body can have at least one slot in such a way that, in the uncoupled state, the bore has a cross section that allows axial decoupling of the hydraulically damping bearing. Furthermore, a tilting movement of the force introduction means of the hydraulically damping bearing is made possible in the event of radial loads. As a result, however, there are essentially no hydraulic damping effects.
- the force introduction means is designed as a clamp arm connected to the spring element, in which a bearing socket is arranged for pivotally accommodating the second coupling element.
- the clamp arm can be arranged on the motor side, while a bearing plate arranged between the spring element and the hydraulically damping bearing is fixed on the body side.
- the second coupling element is designed as a rotating body on which the second force introduction means is fixed, the rotating body having an opening for the first coupling element.
- the second coupling element can be non-positively fixed by means of the first coupling element, whereby the second force introduction element is also fixed on the first force introduction element.
- the first coupling element is fixed to the bracket arm and has a spring arm which penetrates the opening of the second coupling element and which can be actuated by means of an actuator in such a way that the two force introduction means are non-positively connected to one another.

- the hydraulically damping bearing 30 is accommodated, which has a structure which is known in principle.
- the bearing 30 is designed as a two-chamber bearing with a working chamber 31 and an equalizing chamber 32, which are separated from one another by an intermediate plate 33.
- the liquid-filled chambers 31, 32 are connected to one another via an overflow channel 34.
- the compensation chamber 32 is delimited on the bottom side by a rubber-elastic membrane 35.
- the working chamber 31 has a rubber-elastic suspension spring 36, in which a bearing core 37 is received.
- a round bolt 38 protrudes from the bearing core 37 and penetrates the opening 1 6 of the bearing plate 1 3 of the spring element 1 1.
- the first force introduction means which is arranged on the motor side, is formed by the support arm 20 and the hollow-cylindrical extension 18 attached to it. As can be seen from the drawing, the support arm 20 is welded to the neck 1 8.
- a coupling device 21 is received, which has a first coupling element 22, which is slidably guided on the inner wall of the extension 1 8.
- the first coupling element 22 is connected to an actuator 19, which can be present, for example, as an electromagnetic actuator.
- the actuator 19 is connected to the first coupling element 22 via an adjusting screw 26.
