For supporting member 44 is transformed in its expanded position, motor 66 activated, to drive rotating shaft 68 to rotate in a first direction, described first direction is configured to around the rotation of the axis C perpendicular to sidewall 10, to expansion direction, move the first arms 70 by execution on the first arms.In the process of this motion, the first arms 70 is applied thrust on the second arms 78, and the downstream end 80 of the second arms separates and moves downstream on expansion direction with the end, upstream 72 of the first arms 70, as shown in Fig 4.Thereby the second arms 78 promotes axis body 54 along expansion direction, and move in the first paragraph portion 28 of the first guide track 16 end 56 of axis body.Thereby cause the movement of supporting member on expansion direction with the axis body 54 that supporting member 44 is connected together, this moves and rotates movement by causing the translation of teeth parts 60 on the second guide track 34 coordinating of the tooth 64 of teeth parts 60 and the tooth 41 of channelled rail 40.
The arcuate shape of first paragraph portion 28 and the arcuate shape of the second guide track 34 due to the first guide track 16, supporting member 44 moves and rotates mobile around the axis that is substantially perpendicular to sidewall 10 along expansion direction translation downstream, described movement is configured to inner space 12 top and lifts and receive surface 46, and this causes that the corresponding of convex shoulder 48 vert.
, immediately at the first arms 70, rotate after mobile beginning, the first arms is thrown off and is stopped at first connecting rod from the actuator surface 114 of first connecting rod 90 and applies support meanwhile.Thereby bundle limit element 101 drives first connecting rods 90 to rotate opening in direction.Thereby first connecting rod 90 is along retraction direction tractive control stalk 94, and this drives second connecting rod 92 to rotate.The rotation direction of second connecting rod 92 is tractive on the end, upstream 100 of valve 82, and this causes that pin 86 upstream moves in guide rail 88, as shown on Fig. 1, Fig. 2, Fig. 4 and Fig. 5.Thereby valve 82 is positioned at open position and disengages opening 84.
The motion of supporting member 44 is proceeded, and receives surface 46 to be bonded in opening, with from inner space, go out from.
At the stroke end of actuating device, as shown on Fig. 1 and Fig. 2, supporting member 44 is arranged in expanded position, and in expanded position, from inner space, 12 protrusions extend through opening to receive surface 46, and extend in the plane tilting with respect to expansion direction.This clinoplane is for example vertical substantially or upstream omits low dip with respect to vertical line, so that when bearing set 4 is installed in gauge panel, receives surface 46 to extend in the visual field of chaufeur.
In this expanded position, as shown on Fig. 4 and Fig. 6, after in the second segment portion 32 that is bonded on the first guide track 16, the end 56 of axis body 54 is arranged in the locking groove seat 24 of these tracks 16, and teeth parts 60 are arranged in the locking groove seat 42 of the second guide track 34.Because these locking groove seats 24 and 42 are in the corresponding position of the downstream end 20 of the first guide track 16 and the downstream end 38 of the second guide track 34, thereby the convex shoulder 48 of supporting member 44 extends along expansion direction substantially, as shown on Fig. 1 and Fig. 2.
Supporting member 44 is attended by the cooperation between two teeth parts 54 and channelled rail 17 enduringly in the movement between its advanced position and its expanded position.
By activation motor 66, to drive rotating shaft 68 in the second direction contrary with first direction, supporting member 44 moves to advanced position from expanded position to carry out according to a kind of kinematics contrary with kinematics mentioned above.This motion has the effect to the end, upstream 18 of the first guide track and the end, upstream 36 of the second guide track by the end of axis body 54 56 and teeth parts 60 bands, thereby and supporting member 44 is transformed in its advanced position.
Stroke end at the first arms 70, the first arms is exerted pressure on the actuator surface 114 of first connecting rod 90, thereby first connecting rod 90 is rotating with opening in the direction of opposite direction, this has the control stalk of making 94 and on expansion direction, moves and second connecting rod 98 is rotated, to promote the effect of valve on expansion direction.Second connecting rod 92 rotates until the corresponding slot seat and the valve 82 that lean on stop part 102, the guide pin 104 of valve 82 to be placed in the limit portion that is arranged on opening 84 are positioned at make position and sealing opening 84.
By means of 92 of second connecting rods, lean on stop part 102, the make position of valve 82 is stable and always identical.Guide pin 104 is also assisted this consistent location when the each closure of valve.In addition, by means of shock absorber 106, valve 82 does not move in opening, and this absorbs the remaining part stress that apply on valve 82 and/or that come from the vibrations of self-propelled vehicle when operating motor vehicles by bearing set 4.This class stability provides better outward appearance to the bearing set that is positioned at advanced position, and improves the quality by the perception of user institute.
In addition, valve 82 depends on the motion of actuating device to the motion of its open position.Can not drive valve to move to its open position being positioned at the applied external force applying on the valve 82 of make position, this is because resist this movement for the constrained force being applied by the first arms 70 on first connecting rod 90.Therefore, the quality of institute's perception is further improved.
Finally, the mobile Complete Synchronization of the movement of valve 82 and supporting member 44, this when each expansion, provide gratifying, failure-free, firmly with consistent expansion kinematics.
