Definitions
- the invention relates to a damping device for a chassis of a motor vehicle.
- the invention further relates to a stabilizer for a chassis of a motor vehicle and a chassis.
- the wheels or suspension of the respective axle are connected to one another via stabilizers and to the vehicle body in order to reduce the tendency of the vehicle body to tilt, in particular when cornering, as a result of lateral acceleration.
- a torsion bar stabilizer which is connected at its ends with the wheels or suspension
- a copying movement exerts on the opposite wheel or the suspension. This results in a reduced lateral tilt.
- the stabilizer in turn is connected via pendulum supports to the vehicle body. The up and down movements of the vehicle during a journey are transmitted to the stabilizer via the pendulum supports.
- An adjustable roll stabilizer has become known, for example, from DE 10 2014 208 803 A1.
- an actuator is arranged between an output shaft of a transmission and a damping unit in a section of the stabilizer.
- the damping unit is arranged within the actuator housing of the actuator. Excitations in the form of vibrations due to movements of the wheel can thus be conveyed unhindered over a section to the housing. and cause disturbing noises.
- An object of the present invention is therefore to reduce disturbing noises in the acoustic transfer path, in particular to reduce the transmission of noise of an actuator to the vehicle.
- the present invention solves the problem in a damping device for a chassis of a motor vehicle in that the damping device comprises at least one damping element, which is arranged in the end region of a stabilizer between the stabilizer and a connection device for a suspension element, in particular a pendulum support.
- the present invention also achieves the objects in a stabilizer for a chassis of a motor vehicle, characterized in that a damping device is arranged which comprises at least one damping element, which in the end region of the stabilizer between the stabilizer and a connection device for a suspension element, in particular a pendulum support arranged is.
- the present invention also achieves the objects with a chassis with a damping device according to one of claims 1 to 13 and / or with a stabilizer according to claim 14.
- the damping element can be designed both for damping rotationally acting as well as axially acting interference: For example, so unwanted noise can be suppressed by road bumps otherwise directly and undiminished via the wheels and the stabilizer to an actuator and cause noises there.
- the lifetime actuator is also increased for a stabilizer, since by means of the damping element less vibration entry takes place in the stabilizer.
- the damping device takes up little space and is simple in construction.
- the Damping device in particular the damping element to be adapted in a flexible manner to predetermined requirements.
- the damping element is sleeve-shaped. This allows for easy production, easy installation and small footprint.
- the damping device comprises an inner sleeve and / or an outer shell, such that the damping element is arranged on the radial outer side of the inner sleeve and / or on the radial inner side of the outer sleeve.
- the inner sleeve has at its one axial end a nut thread, in particular on the side facing the stabilizer. This allows the inner sleeve by means of a screw, for example, via the connecting device on a pendulum support set in a simple manner.
- the outer sleeve has on one axial side a radial, in particular circumferential, projection, in particular on the side facing the connection device.
- the outer sleeve is formed shorter in its axial extent than the inner sleeve, in particular wherein the axial extent of the outer sleeve of an axial extent of the damping element ent speaks.
- the advantage of this is, in particular the outer sleeve can completely cover the damping element, which on the one hand allows reliable damping, on the other hand increases the life of the damping element, as this is covered by the outer sleeve.
- a further advantage is that a determination of the damping element on the inner sleeve can be carried out in a particularly simple and flexible manner, since a highly accurate positioning of the damping element on the outside is not required by the longer design of the inner sleeve.
- the end portion of the stabilizer is tubular and the outer sleeve is inserted in this. This allows a particularly simple installation of the damping device.
- outer sleeve and stabilizer are integrally formed in its end region. This way, the outer sleeve can be formed directly on the stabilizer, which reduces the number of components.
- stabilizer and outer sleeve by means of a welded joint to each other can be fixed. This allows a simple and reliable setting of stabilizer and outer sleeve of the damping device.
- stabilizer and outer sleeve can be fixed to each other on their respective outer side.
- a simple assembly and fixation of stabilizer and outer sleeve is achieved together.
- the stabilizer on its axial outer side on the radial outer side of the outer sleeve, in particular of the projection can be fixed.
- This allows a particularly reliable fixing without having to provide an additional area for a connection between the stabilizer and the outer sleeve.
- the connection life on different oriented surfaces - once axial outside, once radial outside - increases the life of the compound.
- the damping element is made of acrylonitrile-butadiene rubber. This allows a reliable damping with a long service life.
- the damping element can be fixed to the inner sleeve and outer sleeve by means of compression or by means of adhesion, for example vulcanization, gluing or the like. This allows a simple and reliable fixing of the damping element to the respective sleeve.
- an actuator for generating a torsional moment between two sections of the stabilizer is arranged.
- an active roll stabilizer can be provided.
- Figure 1 shows a damping device according to an embodiment of the present invention
- Figure 2 shows a part of a chassis of a motor vehicle with a stabilizer according to an embodiment of the present invention.
- the damping device 1 shows a damping device 1 according to an embodiment of the present invention.
- the damping device 1 comprising an outer sleeve 2, a damping element 3 on the radially inner side of the outer sleeve 2 and an inner sleeve 4 on the radial inner side of the damping element 3 are arranged.
- the outer sleeve 2 has an axial projection 1 1 on its pendulum support 6 side facing. This projection 11 serves as a stop and prevents the damping device 1 from slipping undefined into the stabilizer tube 5 or from being able to move.
- Stabilizer tube 5 and projection 1 1 are fixed by means of a welded joint 10 to each other. In this case, the radial outer side 13 of the projection 1 1 is connected to the axial outer side 12 of the stabilizer tube 5.
- the inner sleeve 4 extends in the axial direction over a larger area than the outer sleeve 2 and the damping element 3. Outer sleeve 2 and damping element 3 have substantially the same axial extent.
- the inner sleeve 4 On one of its axial sides, here on the side which is inserted in the stabilizer tube 5, the inner sleeve 4 has a female thread 9a with which a nut 9 can be used to fix a screw 8.
- the screw 8 extends through the entire region of the inner sleeve 4 and is connected to a pendulum support 6 for transmitting power.
- the screw 8 in this case forms the connection device 7, with which the pendulum support 6 is connected via the damping device 1 with the stabilizer tube 5.
- the stabilizer tube 5 can be made of a high strength, non-rusting material.
- the damping element 3 can be reliably fixed by means of an adhesive connection or by pressing between inner sleeve 4 and outer shell 2.
- the damping element 3 may be formed, for example, in the form of an elastomeric element, a rubber element or the like.
- Figure 2 shows a part of a chassis of a motor vehicle with a stabilizer according to an embodiment of the present invention.
- FIG. 2 shows in detail the region of a rear axle of a vehicle.
- wheels 202 are connected via a vehicle rear axle 203 with a damper 200 and a strut 201 here.
- Strut 201 and damper 200 are in turn connected to a body 204 of the vehicle.
- the vehicle axle 203 is further connected to a stabilizer assembly 20 to minimize roll motions in steering the vehicle.
- the stabilizer arrangement 20 in this case comprises an actuator 205, which comprises an electric motor 30 and a gear 40, with the two subsections 20a, 20b of the stabilizer assembly 20 are rotated against each other to compensate for said rolling movements of the vehicle.
- the invention enables, in particular in its embodiments, an attenuation of the acoustic transfer path.
- Noise of an actuator for the stabilizer are effectively damped and passed on to the vehicle only to a limited extent.
- the damping is achieved by means of a rubber-like connection between stabilizer end and Pendel monanitati. Further advantages are a simple structure and a small footprint and a high flexibility, because the damping element or the damping device in general can be flexibly adapted to predetermined conditions.
