Technical field
The utility model relates to a kind of brake structure, particularly a kind of motor brake structure.
Background technique
At present, existing motor brake structure mainly comprises brake block, skidding plate, brake supporting plate, brake spring and brake bracing wire, wherein, brake block is connected with skidding plate, skidding plate moved brake pivot pin and was connected actively with brake dunnage, brake spring one end is connected with skidding plate, and the other end is connected with one end of brake dunnage, and one end of brake bracing wire is connected with described skidding plate; Operator is in the time braking, pull skidding plate by bracing wire, the moving brake block of skidding strip brakes, now, owing to receiving the impact of brake spring, just need to overcome very large pulling force, use for a long time, reduce the working life of brake bracing wire, and, the brake structure of this spline structure, relatively takes up room, and does not have versatility.
Model utility content
The purpose of this utility model is just to provide a kind of motor brake structure that can increase the brake bracing wire life-span.
The purpose of this utility model is to realize by such technological scheme, a kind of motor brake structure, comprise one end by brake pivot pin carry out interconnective brake dunnage and skidding plate, also comprise the brake spring for connecting skidding plate and brake dunnage, be provided with brake block at described skidding plate middle part, be provided with the transmission shaft through brake dunnage at the other end of described brake dunnage, the reduction torsion spring that is provided with driver blade in one end of described transmission shaft and resets for driver blade, be provided with the pushing block for promoting skidding plate at the other end of described transmission shaft.
Wherein, described pushing block comprises driven plane, and described driven plane is corresponding with the lower end surface of described brake dunnage one end.
Further, described driver blade and reduction torsion spring are all located on one end of transmission shaft, are provided with transmission lug at the end that penetrates of described driver blade, and one end of described reduction torsion spring is connected with transmission lug, and the other end is connected with brake dunnage.
Wherein, described transmission shaft comprises and is in turn connected into overall thread section, rectangular block and a cylindrical piece, and described driver blade is arranged on rectangular block, and described reduction torsion spring is set on cylindrical piece, on described thread section, is provided with locking nut.
Owing to having adopted technique scheme, the utlity model has compact structure, the reliable advantage of usability, adopt it can overcome the pulling force of brake spring, increase the working life of brake bracing wire.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is fractionation structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement on the present embodiment essence spirit or substitute, still belongs to the utility model claim scope required for protection.
Embodiment 1: as Fig. 1, 2, shown in 3, a kind of motor brake structure, comprise one end by brake pivot pin 1 carry out interconnective brake dunnage 2 and skidding plate 3, also comprise the brake spring 4 for connecting skidding plate 3 and brake dunnage 2, be provided with brake block 5 at described skidding plate 3 middle parts, be provided with the transmission shaft 6 through brake dunnage 2 at the other end of described brake dunnage 2, the reduction torsion spring 8 that is provided with driver blade 7 in one end of described transmission shaft 6 and resets for driver blade 7, be provided with the pushing block 9 for promoting skidding plate 3 at the other end of described transmission shaft 6.
Wherein, described pushing block 9 comprises driven plane 10, and described driven plane 10 is corresponding with the lower end surface of described brake dunnage 2 one end.
Wherein, above-mentioned driver blade 7 and reduction torsion spring 8 are all located on one end of transmission shaft 6, are provided with transmission lug 11 at the end that penetrates of described driver blade 7, and one end of described reduction torsion spring 8 is connected with transmission lug 11, and the other end is connected with brake dunnage 2.
Further describe, described transmission shaft 6 comprises and is in turn connected into overall thread section 12, rectangular block 13 and a cylindrical piece 14, described driver blade 7 is arranged on rectangular block 13, and described reduction torsion spring 8 is set on cylindrical piece 14, on described thread section 12, is provided with locking nut 15.
The utility model is installed on motor, brake one end of bracing wire 17 and one end of driver blade are connected.
The utility model is work like this: the not working state of braking: pull brake bracing wire 16, brake bracing wire 16 pulls driver blade 7, make transmission shaft 6 around transmission shaft 6 central rotations, wherein reduction torsion spring 8 is in compressive state, driven plane 10 on transmission shaft 6 promotes skidding plate 3, brake block 5 around brake pivot pin 1 central rotation, now brake block 5 is in top dead center, and brake spring 4 is in extended state.
Brake working state: brake bracing wire 16 comes loose, under the effect of reduction torsion spring 8, driver blade 7 and transmission shaft 6 are rotated around transmission shaft 6 centers, allow driven plane 10 and skidding plate 3 separate, allow driven plane 10 no longer skidding plate 3 be carried out spacing, under the pulling force of brake spring 4, skidding plate 3 is rotated down around brake pivot pin 1 center, thereby drive brake block 5 to move down, complete brake process.
