    • The invention relates to a brake device of a railway vehicle, comprising at least one operating brake cylinder (10) having at least one operating brake piston (4) actuated by a pressurizing medium, said piston actuating an operating brake piston rod (6) coaxial to the brake cylinder axis (12), and having a parking brake device having a pivotally supported actuating lever (20), the rotary motion thereof being transmitted to a shaft (24) rotationally supported by at least one shaft bearing (22) on a housing (18), wherein the rotary motion of the shaft (24) induced by the actuating lever (20) can be converted to a linear motion parallel to the brake cylinder axis (12) of at least one support roller (42) rotationally supported by a support roller bearing (44) on a rotary axis (76) disposed parallel to the shaft (24), in that at least one cam (50) having an operating cam face (52) and rotationally fixed to the shaft (24) is provided, said cam interacting with a radially outer support roller surface (54) of the support roller (42) during a tightening or releasing stroke of the parking brake device, wherein the linear motion of the support roller (42) is transferred to the operating brake piston rod (6). According to the invention, the operating cam face (52) is designed as a circumferential segment of a cylinder surface, the center axis (66) thereof executing a circular motion path (68) about the shaft axis (70) of the shaft (24) during a tightening or releasing stroke of the parking brake device, wherein an intersection point (72) of said motion path (68) and the brake cylinder axis (12) exists that is substantially associated with a maximum parking brake force.

    • The invention relates to a clamping and/or braking device comprising a base body (3), which has at least a clamping and/or a braking zone for impinging on an element (9), for example, a guide element or an element of a linear guide which is to be clamped. An actuation device is provided on the base body (3) which, during actuation, causes a substantially elastic deformation of the base body (3), so that the clamping and/or braking zone(s) is/are displaced into or out of an impinging position or so that the impinging force which is exerted on the element (9) by the clamping and/or braking zone is modified. The inventive actuation device comprises at least one chamber (15) which is provided on the base body (3) or configured therein and which can be subjected to negative or excess pressure. At least part of said chamber is delimited by at least one wall (13) which is flexible at least in partial areas but is tensile and/or pressure-resistant. The wall (13) is connected to the base body (3) in such a way that when the chamber(s) (15) is/are subjected to excess or negative pressure, tensile or pressure forces are exerted on the base body (3), creating the substantially elastic deformation of the same, or modifying the impinging force which is exerted by the clamping and/or braking zone(s).
    • 具有基体(3)的夹紧和/或制动装置具有用于对元件(9)加压的夹紧和/或制动区域。 基体(3)具有致动机构,其在致动时引起基体(3)的基本弹性变形,使得夹紧和/或制动区域进入或离开加压位置,或者加压力 夹紧和/或制动区域施加在元件(9)上的位置被改变。 致动机构包括至少一个腔室(15),其可以被加压并且位于或结合在基体(3)中并且至少部分地由至少一个壁(13)限定在 其最小部分区域是柔性的,但是具有抗张力和/或耐压性。 壁(13)连接到基体(3),以便确保在最小的一个腔室(15)的加压时,力施加在基体(3)上,这就会产生所述 基体或由夹紧和/或制动区域施加的加压力的变化。
