It is restricted in an appropriate manner in the conceived case.For example, inclined surface correspondingly carries out on braking action direction
The adjustment of braking member with the big gradient, the gradient continuously become flat when starting, until eliminating orbit gap
Inclined surface is transitioned into the constant gradient in region.
It is also advantageous in that stop part of the setting for braking member, the stop part is defined on braking action direction and carries out
Braking member adjustment.Thus the voluntarily destruction of pre- antioverloading and brake casing related to this.It is also advantageous in that
The prestressing force that interface can overcome pressing force to define device is adjusted upward in pressing square.The particularly combination tool of the two measures
There is the advantages of substance.For this purpose, be preferably set up coordinate (Abstimmung), wherein by stop part be implemented so that backstop in
The structural initial pre stress that pressing force defines device is alreadyd exceed by pressing force caused by guide structure before thereon.Therefore it presses
Clamp force defines activation of the device in compaction direction, is simultaneously realized simultaneously which has limited pressing force and defines device pair by pressing force
The setting of pressing force.For different reasons, this can be crucial.Here, the limitation of pressing force can pass through the knot of track
Structure configuration determines.But in order to reach big brake force, the accurate setting under the limitation can be meaningful.However it compresses
The limitation of power can also carry out for other reasons, such as simultaneously therefore the maximum of default lift car subtracts default maximum braking force
Speed.
It is also advantageous in that setting holding structure, the holding structure cooperates with braking member so that braking member is being braked
It contacts in the process and/or in the case where braking member is positioned at its ready position with guide roller unit.It is also advantageous in that herein
The holding structure have at least one spring element, the spring element by braking member be maintained in guide roller unit and/
Or the holding structure has at least one spring element, braking member is maintained in guide roller unit by the spring element,
So that the own wt of braking member is compensated at least partly.It thereby ensures that braking member is corresponded to determine by guide structure
Move against on track, and be then guide further, until for example reaching stop part.Thus braking member can also be avoided
