A disc brake apparatus structured such that, on receiving a pressing force from an operating spring, a piston arranged within a cylinder formed in a caliper body presses a piston side pad. The disc brake apparatus includes a support part formed in a part of the caliper body, a reaction force receiver provided on and projected from the lateral side of the piston and opposed to the support part, and cam parts interposed between the support part and the reaction force receiver and, on receiving a rotation force, capable of spreading the distance between the support part and the reaction force receiver to thereby release the pressing force.

Methods and devices for tensioning a cable are disclosed. The device comprises a nut having two open ends, two bolts, each bolt having a central bore and adapted to mate with one open end of the nut, and two cable securement devices. The cable securement devices are smaller than an inner diameter of the nut and larger than a diameter of the central bores of the bolts.

An actuator assembly has a ball screw drive, having a ball screw spindle rotatably mounted about a spindle axis and on which a spindle nut is received, wherein at least one thread track is formed on an outer circumferential surface of the ball screw spindle, which track extends over less than 360? of the circumference of the ball screw spindle. A ball return is arranged on the outer circumferential surface for each thread track and connects a beginning and an end of the thread track to one another. A ball race for the balls is formed in a separate insert, which is inserted into a depression arranged in the outer circumferential surface. To produce the ball screw spindle, a thread is introduced into the outer circumferential surface of the ball screw spindle and at least one depression is introduced into the outer circumferential surface. The depression defines the beginning and end of a thread track. The insert is inserted into the depression in such a way that its ball race adjoins the beginning and the end of the thread track.

A brake system that includes a brake piston, a rotary to linear stage mechanism, and a clutch. The brake piston extends along a longitudinal axis. The brake piston includes a piston pocket. The rotary to linear stage mechanism includes a spindle and a nut. The nut is received in the piston pocket. The brake system is operable in a first braking application and in a second braking application. During the first braking application, the clutch is adapted to provide for the nut to rotate about the longitudinal axis. During the second braking application, the clutch is adapted to restrict or prevent the nut from rotating about the longitudinal axis.

A spring applied hydraulic release caliper brake includes a housing carrying springs acting on a piston in a default position. The housing further carries an adjuster, with an outer portion of the adjuster being in direct contact with an outermost spring of the springs. A released position of the brake includes the piston being in contact with the adjuster. The adjuster is adapted to rotate a predetermined amount to thereby cause the adjuster to act on the springs. This removes an amount of clearance between the piston and a stator, such that the removal of the amount of clearance becomes a new default position for the spring applied hydraulic release caliper brake.

An electromagnetic active brake which is de-energized in the brake standby state, includinga brake body (1), a brake device with at least two opposing brake shoes (9, 12) which are spaced from a component to be braked in the de-energized state of the active brake, and an electromagnet (5) which is arranged in the brake body (1) and the armature (6) of which interacts with a brake lever (2). The armature (6) of the electromagnet (5) is rigidly connected to a spring compressor (3) which is guided in the brake body (1) and which is moved by the armature (6) in the axial direction of the armature (6) when the electromagnet (5) is energized and in this manner clamps a spring (16) against an abutment (20) that interacts with the brake lever (2) and is arranged in an axially adjustable manner in the direction of the path of the spring compressor (3). The active brake according to the invention is highly energy-saving and thus economical.
