Degree.
Bearing unit according to the present invention so can forcefully be acted on during calibration operation by means of radial load, be made
The pressure load of the bearing components caused by the radial expansion by support unit and the performance of bearing unit generated and its
The duration of behavior can be adjusted or be adaptable to application accordingly without causing any damage to support unit.
In conventional bearing unit, correspondingly high radial load cannot be used for calibrating, this is related with the limited calibration of these bearing units.
Extension component can be made of metal, metal alloy, plastic material or composite material.The quantity for extending component is preferred
Corresponding to the quantity of supporting section.Multiple extension components can be for example, by the connecting elements that is constructed with plate or circular pattern each other
Connection, and therefore can be formed together with connecting elements integral form, single-piece extension member unit.Axis according to the present invention
Bearing unit can have for example, at least two, but can also three, four, five or more supporting sections.It is at least one corresponding
The extension component that ground is only only supported on opposed facing adjacent surface is preferably provided at all opposed facing neighbours of supporting section
Between junction, opposed facing adjacent surface is disposed adjacent circumferentially from one another.It, can by accordingly selecting the form or size of extension component
The performance of bearing unit according to the present invention is adjusted or changes to use bearing components and supporting section, which is manufactured
For the same part, supporting section can be manufactured to the same part, support unit by being used to form the extension component of support unit
Supporting section is forced specific dimensions or therefore to make bearing component deformation desired size away from each other.Can corresponding adjacent surface it
Between axially introduced into or squeeze extension component.So that the sub-component extension or radially expanded formed by supporting section.
The bearing components of hollow cylindrical can partly or preferably completely be made of elastic material such as rubber.Bearing
Component surrounds support unit with radially outward direction.The axial direction that the axial length of bearing components can be different from support unit is long

The mode that the structure and shape of supporting section remain unchanged constructs supporting section.Due to extending component, radially outward supporting section is pushed to make
The performance of bearing unit can individually be adjusted by obtaining.
Bearing unit according to the present invention for example can be used for the walking mechanism or vehicle of the vehicle of especially motor vehicles
The components such as the especially connecting rod (longitudinal rod, transverse link) of body lower member are supported on chassis, subframe or the vehicle frame of vehicle
On element.However, bearing unit can be used for the other purposes except motor vehicle construction, so as to removable and vibration damping
Two components are connected to each other by mode.
According to advantageous embodiment, at least one axially extending groove is at least constructed at least one supporting section
At one adjacent surface, extension component engaged in a manner of positive locking in a groove and the axially extending supporting section of groove at least
A part.Therefore ensure that extension component is correctly positioned relative to the position of supporting section.Due to extending the displacement of component, in bearing
The operation of unit or during use, further prevents the performance change of bearing unit.In addition, by being extended by means of groove guides
Component is simplified introduces extension component between supporting section, this finally simplifies the assembly of bearing unit.It is connect with extension component
Corresponding axial notch can also be constructed at tactile each adjacent surface.
According to another advantageous embodiment, bearing components include at least one cavity, the cavity axially-extending bearing structure
At least part of part, the cavity are configured to radially-inwardly be open and be arranged to relative to extension component at least partly
Radially outward.Therefore, bearing components die down in the radial outer region relative to extension component, but this makes it easier to supporting
Axially introduced into extension component between section, this is because bearing components can be made to be deformed in the region of cavity by small force.
For example, cavity can be configured to oval, oval or polygonal shapes cross sections.Preferably, the quantity pair of the cavity of bearing components
It should be in the quantity of the extension component of support unit.However, the structure of cavity also influences the performance of bearing unit, using suitable
This point is considered during extension component to adjust desired performance.
Another advantageous embodiment provides four supporting sections and four extension components, four supporting sections for support unit
It standalone configuration and is disposed relative to deviate circumferentially from one another, wherein extension component is arranged between two adjacent supporting sections.
Bearing components can be perpendicular to each other and in the both direction that the longitudinal center axis of bearing components extends as a result,
It equably extends or evenly radially inwardly widens, and therefore can be pre-tensioned, wherein it is preferred that the excircle of bearing components
It remains unchanged.
Advantageously, two adjacent surfaces of each supporting section be configured to the longitudinal center axis about bearing components relative to
90 ° are deviated circumferentially from one another.If extension component is still not disposed between supporting section, adjacent to each other circumferentially disposed supporting section
It is supported each other on each other in a planar manner by opposed facing bearing surface.
Bearing according to the present invention particularly for vehicle includes at least two components, and at least two component is via bearing
Unit is movably connected to each other, wherein being appointed each other according at least two in one in above-described embodiment or these embodiments
Technically advantageous combination constructs bearing unit for what.
