In order to ensure the enough firm connections between the outer section of matrix and pad, matrix and outer section preferably interconnect in the mode of shape sealed (formschluessig) and/or material combination (stoffschluessig) and/or force closure (kraftschluessig).
According to another embodiment of the invention, matrix and outer section integrally formed, wherein, outer section has material weakening section.This material weakening section has again such size at this, occurs the inefficacy targetedly of perimeter/break when making the load overload on acting on the normal orientation of matrix.This mode of execution is because it can realize having advantage according to the manufacturing of the simple economy of pad of the present invention.
According to another embodiment of the invention, the centrifugal biasing of through hole is arranged in matrix (bias).The setting of this centrifugal biasing of through hole is because the respective settings of having guaranteed bearing device has advantage.
The present invention is in addition based on following technical problem: improve so the described type of preamble according to claim 7, at the bearing device of second supporting member upper support the first supporting member, thereby can detect damaged condition, i.e. bearing device load has exceeded the maximum, force of a permission of determining.
This technical problem by the characteristic of claim 7 with and the feature of preamble be resolved.
Have in known manner slotted hole for this bearing device first supporting member, the second supporting member remains in this slotted hole by a hinging shaft/cardan shaft that engages (durchfassen) second supporting member.In addition, the second supporting member is threaded with the first supporting member in a known way, wherein is provided with pad between threaded piece and the first supporting member, the outer rim of this pad along the longitudinal direction of slotted hole observe be arranged on the first supporting member on stop configurations contact.
According to the present invention, consist of according to one of claim 1-6 at this pad.Guaranteed in the advantageous mode of tool thus, the inefficacy of pad perimeter or the plastic deformation of pad perimeter have occurred when the load perpendicular to the pad normal orientation of bearing device exceeds the maximum, force of permission.This causes again the displacement of hinging shaft in the slotted hole of the first supporting member, thus the damaged condition that fast detecting occurs.Inefficacy by the perimeter or plastic deformation and displacement have consumed energy in addition, thereby have reduced on the member that continues operation still the power in effect.
Bearing device of the present invention by pad of the present invention is particularly favourable for the supporting of wheel control arm (pull bar) in vehicle structure.Under damaged condition, can continue in principle to travel because the displacement of hinging shaft is little on the one hand thus.On the other hand, the displacement of hinging shaft causes that the appreciable camber of driver is regulated or wheelspan is regulated (the forward and backward bundle of wheel is regulated), and it clearly transmits the signal of damaged condition to the driver.Only damaged cheap, " sacrificial member " that can provide for simple replacement of in this external damaged condition, and the expensive member that continues to move because being lowered, the power effect keeps being without prejudice.
Other advantages of the present invention, feature and application possibility draw by following explanation with in conjunction with the embodiment shown in diagram.
