The present invention provides a parking brake actuator comprising: a motor; a worm gear connected to the motor so that power may be transmitted therebetween; a worm wheel engaged with the worm gear; a driving shaft coupled to the worm wheel and to which a parking cable is connected; and a power transmission gear including a first gear coupled to a rotary shaft of the motor, and a second gear coupled to the rotary shaft of the worm gear and connected to the first gear so that the power may be transmitted therebetween, wherein a gear ratio between the first gear and the second gear is 10:66 and a gear ratio between the worm gear and the worm wheel is 1:54.

A child transport carrier includes a handle bar and a rotatable brake actuator disposed around the handle bar. The rotatable brake actuator includes a first portion having a first radius of curvature and a second portion having a second radius of curvature. The first radius of curvature is less than the second radius of curvature. Rotating the rotatable brake actuator around the handle bar activates a first wheel brake.

A screw actuator comprises a screw shaft for threaded engagement with an actuator output device such that rotation of the screw shaft causes linear movement of the actuator output device; and a motor for driving rotation of the screw shaft. A no-back device is included for restricting movement of the screw shaft in response to feedback torque applied due to external forces on the actuator output device.

A brake mechanism is provided, including: a main body, for connecting to a vehicle, having a penetrating hole for a wire to dispose therethrough, the wire having an insertion end which is smaller than the penetrating hole in radial dimension; a handle, restrictably pivoted to the main body via a pivot portion, having an assembling portion; the insertion end being directly axially penetrable through the penetrating hole to be fixedly connected to the assembling portion.

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.

Disclosed are an electronic control brake system and a method for controlling the same. The method for controlling an electronic control brake system of a vehicle according to the present disclosure, in which a service brake is configured to provide a braking force by hydraulic pressure to each wheel and a drum in hat (DIH) brake is configured to provide a parking brake force to each of the wheels by pulling a parking cable, the method including determining whether rocking of the vehicle occurs due to a weight shift of the vehicle at the DIH brake on the basis of operation information of an electronic parking brake (EPB) system configured to adjust a braking force of the DIH brake, state information of a transmission gear, and state information of a brake pedal; and when the rocking of the vehicle is determined to occur, automatically operating the service brake.

A parking cable has a plurality of plastic split type liners, which reduces frictional resistance between the inner cable and a conduit among the components of the parking cable. The plurality of split type liners is press-fitted and disposed to a desired position in an inner diameter of the conduit. The plastic split type liners may serve as a guide that ensures force for smoothly moving the inner cable and also improve in-line assembly properties. A method of manufacturing the parking cable includes press fitting the plurality of split type liners between the inner cable and the conduit.

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.
