According to the first mode of execution of the present invention, the outer section of matrix and pad is made up of different materials.Such selection is used for the material of outer section, makes it perpendicular to the direction of normal orientation having the intensity lower than the material of matrix.This mode of execution has advantage especially, because can realize the remodeling/correction to known pad thus.
According to another embodiment of the invention, the outer section of matrix and pad is also made up of different materials, and its China and foreign countries' section has material weakened segment, and this material weakened segment has such size, makes the outer section when exceeding maximum, force occur losing efficacy/breaking or plastic deformation.Material weakened segment can be designed in this regard in a different manner, as connection contact pin or the analogous shape of elongated hole, circular hole, inclination.This mode of execution also has the feature that can retrofit.In addition due in this embodiment according to the inefficacy/break of the determination of invention or plastic deformation is realized by the structure of perimeter, so can realize a large amount of material pairings.
In order to ensure the enough firm connection between matrix and the outer section of pad, matrix and the outer section of preferred mode with positive (formschluessig) and/or material combination (stoffschluessig) and/or force closure (kraftschluessig) are interconnected.
According to another embodiment of the invention, matrix and outer section are integrally formed, and wherein, outer section has material weakened segment.This material weakened segment has again such size at this, makes to occur during the load surcharge in the normal orientation acting on matrix the inefficacy targetedly of perimeter/break.This mode of execution has advantage because it can realize the manufacture according to the simple economy of pad of the present invention.
According to another embodiment of the invention, be arranged in matrix through hole centrifugal biased (bias).This centrifugal biased setting of through hole has advantage owing to ensure that the respective settings of bearing device.
The present invention is in addition based on following technical problem: improve like this according to claim 7 preamble type, the bearing device that supports the first supporting member on the second supporting member, thus can damaged condition be detected, namely bearing device load is beyond the maximum, force of a permission determined.
This technical problem is resolved by the characteristic of claim 7 and the feature of its preamble.
Have elongated hole in known manner for this bearing device first supporting member, the second supporting member remains in this elongated hole by the hinging shaft/cardan shaft of joint (durchfassen) second supporting member.In addition, the second supporting member is threaded with the first supporting member in a known way, wherein between threaded piece and the first supporting member, is provided with pad, and the outer rim of this pad is observed along the longitudinal direction of elongated hole and contacted with the stop configurations be arranged on the first supporting member.
According to the present invention, form according to one of claim 1-6 at this pad.Ensure that in the advantageous mode of tool thus, occur the inefficacy of pad perimeter or the plastic deformation of pad perimeter when the load perpendicular to pad normal orientation of bearing device exceeds the maximum, force of permission.This causes again the displacement of hinging shaft in the elongated hole of the first supporting member, thus detects occurred damaged condition fast.In addition consume energy by the inefficacy of perimeter or plastic deformation and displacement, thus reduce and continuing on the component run still in the power of 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.Thus under damaged condition, on the one hand because little can the continuation in principle of displacement of hinging shaft travels.On the other hand, the displacement of hinging shaft causes the appreciable camber of driver to regulate or wheelspan regulates (the forward and backward bundle of wheel regulates), and it clearly transmits the signal of damaged condition to driver.That only damaged cheapness in this external damaged condition, that can provide for simple replacement of " sacrificial member ", and the high cost component continuing to run keeps being without prejudice because power effect is lowered.
Other advantages of the present invention, characteristic sum application possibility draws by explanation below with in conjunction with the embodiment shown in diagram.
Accompanying drawing explanation
Be described in detail by the embodiment shown in accompanying drawing below.
The title and affiliated reference character that reference numerals list below uses quoted by specification, claim and accompanying drawing.In accompanying drawing:
Fig. 1 illustrates according to pad of the present invention, and
Fig. 2 illustrates bearing device that the pad by means of Fig. 1 is formed, automobile chassis control arm.
Embodiment
Fig. 1 illustrates the pad totally represented with reference character 10.The circular pad 10 formed has matrix 12 and outer section 14 in the present embodiment.Matrix 12 and outer section 14 are integrally formed at this.
As also known from Fig. 1, matrix 12 has centrifugal biased through hole 16.Matrix 12 is made up of solid material, and outer section 14 has multiple material weakened segment 18, thus external margin 20 is connected with matrix 12 by means of only multiple connecting sheet 22.
Material weakened segment 18 and connecting sheet 22 have such size, make a regulation, be exceeded perpendicular to the maximum, force of the normal orientation effect of matrix 12 time, connecting sheet 22 is out of shape and indicates this maximum, force thus and is exceeded.
Fig. 2 illustrates the bearing device 100 used according to pad 10 of the present invention.
First supporting member of subframe 110 form has elongated hole 120, supports the second supporting member of chassis control arm 130 form in this elongated hole by pad 10 adjustable ground being designed to centrifugal coil.
As also known from Fig. 2, centrifugal coil 10 contacts with the stop configurations 140 be formed on subframe 110 by its outer rim 20.
If there is damaged condition, namely along the load of the longitudinal direction of elongated hole 120 higher than allowed maximum, force, so pad 10 lost efficacy targetedly, and this causes again the displacement of chassis control arm 130.
The camber that can be perceived by this now driver is regulated or wheelspan regulates, and driver is obtained needs the signal that repairs.
