The otch 115 being located in structure 110 between first protuberance 113 and the second protuberance 114 is chosen relatively large or deep, because
This, can be achieved the effect above.It means that the first protuberance 113 and the long enough of the second protuberance 114, it is allowed to the first protuberance
113 and/or second protuberance 114 elastic bending (or deformation).The elastic bending is for example including the first and second protuberances
Stretching, extension, this stretching, extension can be such that the first protuberance 113 moves in y-direction, and the second protuberance 114 is moved up in the opposite direction
It is dynamic.
In addition, can equally select the cross section structure of the first protuberance 113 and/or the second protuberance 114 so that around x-axis
It may be resiliently deflected in the case of (that is, along the lever arm of clamp lever arm structure 110,210) relative torsion.Should be with so side
Formula selects the selected cross section：I.e. so that the first protuberance 113 and/or the second protuberance 114 are due to the work on y directions
Firmly and may elastic bending exactly, this order of accuarcy is reversed required by maximum angle (referring to Fig. 2).
Due to there are a variety of possibilities, therefore, the invention is not limited in clamp lever arm structure 110 or the spy of certain material
Determine cross sectional dimensions.Importantly, the physical dimension and/or selected material of selection can provide the elastic effect of restriction.
In the case of simplest, mode of the selection material (flexible material) along the thickness of bending direction depends on acting on the material
Brake force.
But, in all exemplary embodiments, it is important that clamp lever arm structure 110 can reliably absorption brake
The braking moment that activating occurs, brake force is reliably delivered to brake lining 45.Maximum angle limits clamp lever arm simultaneously
The possible maximum flexion that structure 110 is allowed.
The bullet performance compensation brake disc being defined by this way and the spaced winding car of brake lining of clamp lever arm structure 110
The relative rotary motion that longitudinal axis (for example, during compression is hung) is carried out, can guarantee that brake disc and brake lining in braking
The positioned parallel of period.Meanwhile, it is possible thereby to which caliper unit is fixedly secured into Vehicular turn on all direction of rotation
On frame or framework, and braking ability will not become negatively affected.Therefore, fixed structure 160 can be relatively easy and compact
Configuration.Brake lining base 40 can be equally secured directly in clamp lever arm structure 110.Therefore suspension bracket or elasticity are not required
Connector or swivel bearing.Because according to exemplary embodiments, fixed structure 160 prevent caliper unit and bogie/framework it
Between relative motion, therefore, caliper unit or the unit that can be fastened to thereon can not be due to air hose or the horizontal strokes of Bowden cable
Moved to active force.
