    摘要: The present invention provides for a one piece band member (10) for use with transmissions. The band member (10) is integrally constructed having the end portions (16) of a strap member (12) being formed an apply member (18) and a reaction member (20) and then folded (22) back over the outer circumference of the strap member (12) to provide a unitary unit. A friction lining (14) is placed around the inner circumference of the strap member (12).

    摘要: Die Erfindung betrifft eine selbsttätige Nachstellvorrichtung für eine Außenbandbremse (11). An den sich gegenüberliegenden Bremsbandenden (23, 25) sind zwei Ankerzapfen (37,39) befestigt, die von einem Bremsgestänge bei nicht betätigter Bremse so weit im Abstand voneinander gehalten werden, daß das Bremsband (21) nicht an der Bremstrommel (17) anliegt. Bei Bremsbetätigung werden die beiden genannten Ankerzapfen (37,39) gegeneinander gezogen. Zur Kompensation des Bremsbandverschleißes ist eine Gestängeverbindung (47) vorgesehen, auf deren eines Ende ein Klinkenrad (53, 55, 57) aufgeschraubt ist, durch deren Verdrehung sich der Abstand zwischen den beiden Ankerzapfen (37, 39) verändern läßt. Über einen Klinkenhebel (83) erfolgt die Verdrehung des Klinkenrades (53, 55, 57) entsprechend dem zunehmenden Bremsbandverschleiß. Sowohl das Bremsgestänge als auch das Gestänge für das Nachstellen des Klinkenrades (53, 55, 57) werden durch einen Hydraulikzylinder (63) betätigt.

    摘要: Disclosed is an electric actuator having a hand-screw release device, including: a housing, a drive motor, a transmission assembly, a rotary screw rod (20) and a driving nut (21), and further including: a clutch device configured to engage or disengage power transmission between the transmission assembly and the rotary screw rod (20); a self-locking device configured to produce a friction resistance against the rotary screw rod (20) when the rotary screw rod (20) rotates reversely; and a hand-screw release device including a release rotary knob (55), the first driving member being connected to the clutch device, the second driving member being configured to connect the self-locking device, and the release rotary knob (55) being turned to present an initial state and a completely released state, wherein in the course of switching from the initial state to the completely released state, the first driving member activates the clutch device to disengage the power connection, and the second driving member activates the release torsion spring (43) to release.

    摘要: The invention relates to a friction-band brake comprising a rotating cylinder (1) having a friction band (2) wound around at least one part of its periphery. The inventive brake also comprises a support (3) for said friction band, which can rotate around a first axis in a first braking position and exhibits two halt points (10, 11) for respective opposed end parts of the friction band. A first halt point has, relatively to the first axis, a lever arm (a) which is longer than the second halt point. According to the invention, the support (3) can rotate in a second braking position around a second axis relative to which the second halt point exhibits a longer lever arm.
