Embodiment
Composition graphs 2 to Fig. 4, the utility model is further described:
Shown in composition graphs 3, a kind of brake shoe mounting structure for automobile drum brake, comprise brake backing plate 10 and be arranged on the brake shoe 20 in brake backing plate 10, the inner side surface of described brake backing plate 10 is provided with mounting bracket 30, described mounting bracket 30 is provided with mounting hole 31, the installation flat board 21 of brake shoe 20 is provided with pull bar 40, pull bar 40 rod end through brake shoe 20 can be in respectively to align with the mounting hole 31 on mounting bracket 30 by with rotary shifted non-return two kinds of cooperation position states.
Utilize the installation that pull bar 40 realizes between brake shoe 20 and brake backing plate 10, by being arranged on the mounting hole 31 on the mounting bracket 30 of brake backing plate 10 inner side surface, thus realize pull bar 40 and the mounting hole 31 on mounting bracket 30 align by coordinating with the non-return that misplaces, and then facilitate installation and the dismounting of pull bar 40 and mounting bracket 30, the installation of this brake shoe 20 and brake backing plate 10, without the need to offering mounting hole on brake backing plate 10, current can be avoided to enter in break, and then the Braking efficiency of break can be guaranteed, this mounting structure is simple simultaneously, field-strip is convenient.
The mounting hole 31 of described mounting bracket 30 is non-circular hole, and the profile of the projection of rod end in horizontal plane of pull bar 40 conforms to the pass of mounting hole 31, and the rod end diameter of pull bar 40 is less than shaft diameter.
Further, be connected with the stable of brake backing plate 10 for realizing brake shoe 20, described pull bar 40 is arranged with spring 50, the upper rod end of pull bar 40 and spring 50 against, lower rod end through installing the through hole 211 that arranges on dull and stereotyped 21 and coordinating with the mounting hole 31 on mounting bracket 30.Utilize the spring 50 that is arranged on pull bar 40, thus be supplied to the elastic tensioning power of pull bar 40, and then brake backing plate 10 can be realized with braking and listen the elastic tensioning of 20 to be connected.
Further, the mounting hole 31 on mounting bracket 30 aligns by with the mode of dislocation non-return two kinds of cooperation position states being: described mounting hole 31 is bar hole, and the lower rod end of pull bar 40 is inverted T-shaped structure.Utilize said structure only need be alignd can insert with mounting hole 31 in the lower end of pull bar 40, the dislocation of pull bar 40 times rod ends and mounting hole 31 can be realized by rotating tension bar 40, and then realize limiting the non-return of pull bar 40.
Composition graphs 4, first bar section of described pull bar 40 arranges in step shaft-like, the large footpath section of pull bar 40 and the end of spring 50 against, the bar head of this step shaft-like, the gripping of easy-to-operat person and maintenance, the path section of pull bar 40 stretches in spring 50, and the lower end abutment of spring 50 is at dull and stereotyped 21 upper plate surfaces of the installation of brake shoe 20, and second bar section of pull bar 40 stretches into brake shoe 20 and installs the through hole 211 arranged on dull and stereotyped 21.
For guaranteeing that brake shoe 20 is covert along brake backing plate 10 radial direction, the aperture that brake shoe 20 installs the through hole 211 arranged on dull and stereotyped 21 is greater than the bar footpath of second bar section of pull bar 40.Keep for the distance moved radially of the installation flat board 21 on brake shoe 20, guarantee that brake shoe 20 can radial deformation, certainly, above-mentioned amount of deformation is extremely small, that is bar footpath, the bar footpath difference of the aperture of through hole 211 and second bar section of pull bar 40 is relatively little, between 0.5mm to 1.0mm.
Finally, described mounting bracket 30 is in grooved platy structure, and mounting bracket 30 notch edges extension is provided with flange, and the inner side surface of this flange and brake backing plate 10 is welded and fixed.
