Brake handle rotating band moving cam formula horizontal mobile device work makes the brake lining motion and contacts with brake disc, thereby through frictional force brake disc is carried out parking braking; When the take-off the brake handle, under the effect of break body medi-spring power, brake lining is separated with brake disc; When the excesssive gap between brake lining and the brake disc or when too small; Through the rotation of adjustment nut, drive brake handle and cammingly horizontal mobile device and on the caliper connecting rod of break body, move, thereby change the gap length between brake lining and the brake disc; Owing to designed adjustment nut and cammingly horizontal mobile device; Rotation through the adjustment nut can make cammingly horizontal mobile device and brake lining directly carry out transverse movement, and the gap of therefore adjusting between brake lining and the brake disc is more convenient.
The utility model has designed; The cammingly horizontal mobile device is set to include retainer, outside bidirectional cam, inboard bidirectional cam and steel ball; The break body includes interior caliper, spring steel plate, braking bolt, outer caliper and brake lining; Interior caliper, outer caliper, inboard bidirectional cam, outside bidirectional cam and brake handle set gradually to being serially connected on the braking bolt; Interior caliper and outside be provided with spring steel plate and brake lining between the caliper; One end of spring steel plate is set to connect with the sports association that makes up tong and the other end is set to connect with outer caliper; Brake lining is set to connect with the brake disc contact-type, between inboard bidirectional cam and outside bidirectional cam, is provided with steel ball and retainer, and steel ball is arranged in the hemispheric groove of inboard bidirectional cam and outside bidirectional cam and is set to connect with inboard bidirectional cam and outside bidirectional cam contact-type; Steel ball is arranged in the endoporus of retainer and is set to connect with the retainer rotary type; Inboard bidirectional cam is set to connect with outer caliper plug-in type, and brake handle is set to connect with outside bidirectional cam plug-in type, adjusts nut and is set to connect and be set to the braking bolt thread type connect with the brake handle contact-type.
The utility model has designed, and steel ball is set to three and be set to be evenly distributed on the circle edge of retainer.
The technique effect of the utility model is: during braking, through brake pulling wire rolling brake handle, brake handle can two-wayly rotate; Through adjustment adjustment nut; Adjustment brake lining and brake disc gap, this Parking Brake is a floating structure, the pulling brake handle; The brake disc axial direction moves caliper in the supporting sleeve upper edge, and brake lining contacts with brake disc entirely; Take-off the brake handle, caliper and brake lining separate under the effect of spring steel plate.
Four, description of drawings
Fig. 1 is the schematic representation of the utility model.
Five, embodiment
Accompanying drawing is an embodiment of the utility model; Specify present embodiment in conjunction with accompanying drawing; Caliper 1, spring steel plate 2, braking bolt 3, outer caliper 4, retainer 5, brake handle 6, adjustment nut 7, outside bidirectional cam 8, inboard bidirectional cam 10, steel ball 9 and brake lining 11 in including; Interior caliper 1, outer caliper 4, inboard bidirectional cam 10, outside bidirectional cam 8 and brake handle 6 set gradually to being serially connected on the braking bolt 3; Interior caliper 1 and outside be provided with spring steel plate 2 and brake lining 11 between the caliper 4; One end of spring steel plate 2 is set to connect with interior caliper 1 and the other end is set to connect with outer caliper 4; Brake lining 11 is set to connect with the brake disc contact-type, between inboard bidirectional cam 10 and outside bidirectional cam 8, is provided with steel ball 9 and retainer 5, and steel ball 9 is arranged in the hemispheric groove of inboard bidirectional cam 10 and outside bidirectional cam 8 and is set to connect with outside bidirectional cam 8 contact-types with inboard bidirectional cam 10; Steel ball 9 is arranged in the endoporus of retainer 5 and is set to connect with retainer 5 rotary types; Inboard bidirectional cam 10 is set to connect with outer caliper 4 plug-in types, and brake handle 6 is set to connect with outside bidirectional cam 8 plug-in types, adjusts nut 7 and is set to connect and be set to braking bolt 3 thread types connect with brake handle 6 contact-types.
In the present embodiment, steel ball 9 is set to three and be set to be evenly distributed on the circle edge of retainer 5.
When using present embodiment; Be supported on interior caliper 1 on the fixing bolt 12 through supporting sleeve 15 with outer caliper 4; Caliper 1 moves along supporting sleeve 15 axial directions with outer caliper 4 in making, and moves on caliper 1 and the outer caliper 4 and with interior caliper 1 and outer caliper 4 in two brake lining 11 are suspended on respectively.Brake pulling wire is fixed on the brake handle, during Parking, and pulling brake pulling wire rolling brake handle 6; Drive outside bidirectional cam (8) rotation, under the pretightening force effect, three steel balls 9 roll hemispheric groove away from along the certain track rotation together; Promoting inboard bidirectional cam 10 moves; Drive brake lining 11 motions through outer caliper 4, brake lining 11 contacts with the brake disc that is rotating and produces surface friction drag, realizes parking braking; When take-off the brake handle 6, under the elastic force effect of spring steel plate 2, three steel balls 9 return in the hemispheric groove along the certain track rotation together, and brake lining 11 breaks away from brake disc.
