摘要： A rail vehicle slack adjuster in a brake unit has an axially movable piston rod (7), a non-rotatable, brake force delivering spindle (8), an adjuster nut (26) in non-self-locking engagement with the spindle and rotating on a bearing (18), and a barrel spring (29) between the unit piston (3) and the spindle, the adjuster nut being clutchable over a main clutch (27) to the piston rod for transmitting brake force. A non-rotatable locking sleeve (20), which is only axially movable a control distance (A) under the action of a locking spring (21), is clutchable to the adjuster nut over a control clutch (28).

摘要： A wedge brake arrangement for drum brakes on heavy road vehicles includes a brake cylinder push rod (29), plungers (26) axially movable perpendicularly to the push rod, and force transmitting rollers (32) between parallel wedge surfaces at the end of the push rod and on the respective plunger. In order to obtain full control over the reaction forces from the plungers (26) at brake operation the push rod (29) is guided by the housing (25) of the arrangement in the plane of the plungers by means of guide rollers (35) between plane surfaces at the end of the push rod (29) and in the housing (25), respectively, the surfaces being parallel with each other and with the axis of the push rod.

摘要： A device for mechanically transforming a torque into an axial force.A long, cylindrical rubber body (16) is enclosed within a tightly wound coil spring (15) and on its short sides by an axially fixed, torque-receiving end wall (12) and an axially movable, force-transmitting cover (17) respectively. One of the ends of the spring accompanies the end wall as it rotates, in so doing causing the diameters of the spring and the rubber body to reduce and the length of the body to increase.

摘要： A rail vehicle slack adjuster is provided with a barrel detented against rotation under normal working conditions. However, rotation of the barrel effects adjustment of the length of the adjuster. Thus, by means of a flexible clip ring splined to the barrel and detenting into a notch on the non-rotatable pull rod, manual force permits the clip ring to be distorted out of the notch for rotation of the barrel to accomplish manual adjustment when replacing brake blocks, or the like.

摘要： A device for transmitting torque between two rotatable shaft members (2, 3) in a stationary housing (1) contains a number of alternate clutch discs (10, 11) engageable to counteract differential rotational speed between the two shaft members, to which they are connected, a hydraulic clutch piston (12) to engage the clutch discs and a hydraulic pump arrangement (15-24) driven by the speed differential between the two shaft members. An annular control piston (15) is axially movably arranged in the housing and is in contact with control pins (17), which are rotatable together with one of the shaft members (3) and cooperate with a cam curve (20) in the other shaft member (2) in such a way that the control pins and thus the control piston are imparted an oscillating movement with a frequency directly proportional to the rotational speed differential between the two shaft members.

摘要： A device for discontinuing and automatically restoring the operational function of a spring brake actuator. The device includes a piston with a piston rod and a spring for actuating the piston and piston rod in a working direction for brake application at falling brake fluid pressure on the piston. A slitted, resilient locking ring is arranged in grooves facing each other in the piston rod and a piston rod sleeve coaxial therewith. The locking ring can either be constrained to rest in both of the grooves, so that the piston rod and piston rod sleeve are locked together, or be free to be forced completely into one of the grooves, which is at least as deep as the thickness of the ring, so that the piston rod and piston rod sleeve are free to move independently of each other. In a compartment in a piston rod flange are arranged a movable locking yoke, which can engage heads at the respective ends of the ring for keeping them together, and a locking cube, which is movable by a control rod substantially perpendicularly to the yoke will move the yoke toward the locking ring and lock the yoke in engaging condition with the ring when the locking cube is above the yoke.

摘要： A rail vehicle block brake actuator (1) shall be fixedly mounted, but its brake block holder (4) shall brakingly engage an axially movable wheel (25). For this purpose the brake block holder is laterally movably suspended relative to the brake actuator by means of pivotable hangers (5) each consisting of a stack of leaf springs. These leaf springs (5) are preferably prestressed in a direction for compensating for the bias of the taper of the wheel tread, which it is intended to engage, but are held in a straight condition by means of a flat bar (9).
