The utility model has the following contents:
the utility model discloses the technical problem that will solve is: the defects of the prior art are overcome, and the double-positioning type air bag clutch which is reasonable in design, high in working efficiency and good in positioning effect is provided.
The technical scheme of the utility model is that:
the utility model provides a two location type gasbag clutches, includes rim, brake shoe, friction disc, gasbag, spring leaf and curb plate, be provided with annular positioning groove on two upper and lower terminal surfaces of rim respectively, the curb plate is two, is located two respectively in the annular positioning groove, the external diameter of curb plate with the internal diameter size of annular positioning groove suits, two the curb plate pass through fastening bolt with rim fixed connection, and, two the curb plate with equally divide between the rim and do not set up two positioning bolt at least, be provided with corresponding perforating hole on curb plate and the rim, the outer end of inflating and deflating the trachea of gasbag is followed wear out in the perforating hole, two clearance fit.
Threaded holes are formed in the two end faces of the wheel rim respectively, and the positioning bolts penetrate through the through holes in the side plates and are screwed with the threaded holes to achieve positioning.
And corresponding mark lines are arranged on the two side plates and the wheel rim, so that the positioning bolt and the fastening bolt can quickly determine the position.
Torsion bars are arranged between the two side plates at intervals along the circumference, each torsion bar is sleeved with a brake shoe, and the inner surface of each brake shoe is provided with the friction plate.
The utility model has the advantages that:
1. the utility model discloses a dual location both improves the efficiency of installation, increases the degree of accuracy of location again, and labour saving and time saving has alleviateed intensity of labour.
2. The utility model discloses the interval sets up the sign line on rim and curb plate, can correspond fast, and the position, convenient and fast are confirmed to the positioning bolt of being convenient for.
3. The utility model discloses the friction disc is fixed at the internal surface of brake shoe, moves along with the brake shoe to the brake shoe can carry out the rotation a little, and the friction disc of being convenient for closely laminates with the pivot, improves and holds the brake effect tightly.
4. The utility model discloses set up the excircle and add the positioning groove location, can rectify the rim and guarantee the concentricity at the out-of-round phenomenon of course of working, reduce the during operation equipment vibration and take place.
5. The utility model relates to a rationally, work efficiency is high and fix a position effectually, easily popularizes and implements, has good economic benefits.
Description of the drawings:
FIG. 1 is a schematic structural view of a dual detent type air bag clutch;
figure 2 is a top view of the dual detent air bag clutch shown in figure 1.
The specific implementation mode is as follows:
example (b): referring to fig. 1-2, the structure comprises a side plate 1, a friction plate 2, a brake shoe 3, an air bag 4, an inflation and deflation pipe 5, a spring leaf 6, a torsion bar 7, a wheel rim 8, a cushion block 9, a fastening bolt 10, an annular positioning groove 11 and a positioning bolt 12.
Double-positioning type air bag clutch comprises a rim 8, a brake shoe 3, a friction plate 2, an air bag 4, a spring piece 6 and a side plate 1, wherein: be provided with annular positioning groove 11 on two upper and lower terminal surfaces of rim 8 respectively, curb plate 1 is two, be located two annular positioning groove 11 respectively, curb plate 1's external diameter size suits with annular positioning groove 11's internal diameter size, the two clearance fit, the size in clearance is decided by positioning accuracy, two curb plates 1 pass through fastening bolt 10 and rim 8 fixed connection, and, equally divide between two curb plates 1 and the rim 8 and do not set up two positioning bolt 12 at least, be provided with corresponding perforating hole on curb plate 1 and the rim 8, wear out in the perforating hole is followed to the outer end of the trachea 5 that fills of gasbag 4, the two clearance fit. In the figure, the two clutches are fixed together, and a cushion block 9 is arranged in the middle.
Threaded holes are respectively formed in two end faces of the rim 8, and the positioning bolts 12 penetrate through the through holes in the side plates 1 to be screwed with the threaded holes to achieve positioning. Corresponding marking lines (not shown in the figure) are arranged on the two side plates 1 and the wheel rim 8, so that the positioning bolts 12 and the fastening bolts 10 can be conveniently and quickly positioned.
Torsion bars 7 are arranged between the two side plates 1 at intervals along the circumference, each torsion bar 7 is sleeved with a brake shoe 3, and the inner surface of each brake shoe 3 is provided with a friction plate 2.
When the clutch is installed, the side plate 1 is placed in the annular positioning groove 11 of the rim 8, so that the central position of the side plate can be relatively positioned, the positions of the fastening bolt 10 and the positioning bolt 12 can be further conveniently determined, and the clutch can be quickly assembled. The friction plate 2 is pressed inwards by the expansion of the air bag 4, so that the purpose of holding the brake is achieved. The spring piece 6 plays a role in resetting and can enable the friction plate 2 to be better separated from the rotating shaft.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
