Further again, described main casing is installed on the electric motor car support by screw, and the pad of regulating active friction plate and brake disc distance is installed between described main casing and the electric motor car support.
Described steel ball initially is positioned at the bosom of symmetrical steel ball slot rolling, and rotating shaft this moment and push rod are fitted; When rotating shaft is rotated, drive steel ball and in the push rod slot rolling, roll, steel ball rolls gradually to the most shallow place of push rod slot rolling, and all the time in the bosom of rotating shaft slot rolling, this moment, push rod was gradually by steel ball jack-up.
For preventing the slide relative of brake arm and rotating shaft, what adopt in the joint is square groove and being connected of square spigot; In order to prevent that push rod also rotates in the rotating shaft rotating process, a projection is arranged on the flange of push rod, just in time be positioned at the vertical square groove of main casing inside, thereby stoped the rotation of push rod; The other end of brake arm connects parking brake or service brake by steel wire.
Working principle of the present utility model: drive the steel wire that links with brake arm by parking brake or service brake, thereby make the brake arm swing, further driving rotating shaft rotates, steel ball between rotating shaft and the push rod is rolled along slot rolling, thereby steel ball jack-up push rod, further jack-up active wearing piece makes two wearing piece closures, the braking steel ring that clamping mediates, thus reached the effect of braking; After unclamping parking brake or service brake, push rod is return previous position under the effect of Returnning spring, and the steel ball between rotating shaft simultaneously and the push rod is rolled to initial position along slot rolling, has so just finished braking process one time.
Advantage of the present utility model: 1, adopt the ball type propulsion mode, make that brake is sensitive, the life-span is long; 2, the controllability of the initial position of wearing piece, initiatively wearing piece can be regulated by pad is installed between main casing and electric motor car support, and the static friction sheet is regulated by adjusting screw; 3, wearing piece is fixed by magnet, has so both reached fixing effect, can be convenient for changing wearing piece again.
