摘要:
L'invention concerne un frein à disque à étrier mobile. Le frein comprend un support fixe qui reçoit en coulissement et en ancrage deux éléments de friction susceptibles de venir en engagement avec le disque, l'un sous l'action d'un moteur de frein et l'autre par réaction au travers de l'étrier. L'étrier est relié au support fixe par des moyens de liaison déformables évitant la venue en contact de l'étrier sur une quelconque partie due support fixe lors des déplacements de l'étrier. L'invention s'applique au freinage des véhicules automobiles.

The invention relates to an electric motor with an electromagnetically actuated brake and cooling channels which extend into a distribution duct (11) located in a housing part of the motor, the brake includes a coil member (7), in particular a magnet member, in which an energizable coil is accommodated, a pipe (4) which runs through a bore in the coil member (7) extends into the distribution duct (11). A seal (42) is arranged axially between a first housing part, in particular an intermediate part (9), and a second housing part, in particular a coil body (7), said seal sealing the inner area of the brake counter to the external surroundings. Said seal (42) seals the inner area of the brake towards the pipe (4). In particular, an intermediate part (9) radially surrounds, forming a housing, an armature plate (8) of the brake and a brake lining carrier (15) of the brake and comprises an axial continuous bore, through which the pipe extends.

A brake assembly includes a service brake assembly and an electromechanically actuable parking brake assembly. The electromechanically actuable parking brake assembly has a ball nut assembly comprising a ball screw and a ball nut. The ball screw and ball nut form a raceway for bearing members. The bearing members circulate within an internal path formed in the ball screw.

The invention relates to a friction brake (1), in particular for elevators, comprising at least two pivotably arranged brake levers (2), which each have a brake lining (6) and are arranged opposite each other in the form of a pair of brake tongs. An actuator (5) is provided for actuating the friction brake (1). In order to avoid uneven loading of the brake levers (2) lying opposite each other, the actuator (5) is designed in such a way that the force (F A ) exerted by the actuator (5) acts substantially perpendicularly to a brake application force (F z ) exerted by the brake levers (5). Furthermore, a spreading mechanism (9, 26) is provided, by means of which the brake application force (F z ) can be regulated by the force (F A ) exerted by the actuator.
摘要:
Die Erfindung betrifft ein Flurförderzeug (1), insbesondere Kommissionierflurförderzeug mit einem anhebbaren und absenkbaren Fahrerstand (5), wobei das Flurförderzeug (1) mit einem lenkbaren Antriebsrad (9) und mindestens einer nicht-gelenkten Lastrolle (8) auf einer Fahrbahn abgestützt ist, wobei das Antriebsrad (9) mittels einer Bremseinrichtung versehen ist und die Lastrolle (8) mit einer als elektrisch lösbaren Federspeicherbremse (15) ausgebildeten Bremseinrichtung versehen ist. Die Aufgabe, eine Lastrolle mit einer Bremseinrichtung zur Verfügung zu stellen, die hinsichtlich des radialen Bauraumbedarfs verbessert ist, wird erfindungsgemäß dadurch gelöst, dass die Lastrolle (8) in einer von zwei seitlich beabstandeten Seitenplatten (10a, 10b) gebildeten Lagergabel (10) drehbar gelagert ist, wobei in den Lagerplatten (10a, 10b) ein Tragzapfen (12) beidseitig abgestützt und drehfest befestigt ist, auf dem die Lastrolle (8) mittels einer Radlagerung (11) drehbar gelagert ist, wobei die Federspeicherbremse (15) einen Elektromagnetaktuator (16) aufweist, der auf dem Tragzapfen (12) angeordnet und drehfest befestigt ist.

The invention relates to a hoisting winch including: a frame (1) supporting (i) a drum (2) that can be rotated about an axis Δ in order to wind a cable or the like and (ii) a main drive system (5) for rotating the drum (2) in accordance with an instruction; a safety system (S) comprising a so-called hollow toothed wheel (12) rotatably secured to the drum (2) and a worm gear (13) that engages with the hollow wheel (12) and is rotated by a follower drive system; and control means designed to control the follower drive system in order to rotate the screw, allowing the rotation of the hollow wheel (12) according to the instruction for rotating the drum (2). According to the invention, the safety system (S) further includes: at least one brake disk (10) which can rotate about a rotational axis and supports the worm gear (13) and the follower drive system; and at least one brake caliper (25) which is attached to the frame (1) and includes a jaw (26) that is locked in a position in which it is clamped to the disk (10), but can be opened.
