[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a drum brake pad isolation suspension. Figure 1 and Figure 2 The drum brake pad barrier suspension includes two columns 1 and a crossbeam 2. The two ends of the crossbeam 2 are respectively connected to the top of the two columns 1. The bottom of the crossbeam 2 is slidably equipped with two groups of barrier units 3. The sliding direction of the barrier unit 3 is the length direction of the crossbeam 2. The gap width between the two groups of barrier units 3 is adjustable. The roller mold for rotating the drum brake pad is located in the gap. A servo drive power group 4 is provided on the crossbeam 2. The servo drive power group 4 is used to drive the two groups of barrier units 3 to approach or move away from each other.

[0030] The beneficial technical effects of the drum brake pad isolation suspension of the embodiment of the present application are roughly as follows:

[0031] According to the width of the drum brake pad, the servo drive power group 4 is started to drive the two groups of barrier units 3 to move closer to or away from each other, thereby isolating the drum brake pads on both sides of the roller mold. In the process of rotating and conveying the drum brake pads on the roller mold, the drum brake pads are not easy to skew or offset, and can adapt to the warning line grinding processing of drum brake pads of various widths.

[0032] In this embodiment, the servo drive power group 4 includes a barrier servo motor 41, a bidirectional screw rod 42 and two sliding blocks 43. The bidirectional screw rod 42 is arranged along the length direction of the beam 2. The bidirectional screw rod 42 is rotatably assembled on the beam 2. The bidirectional screw rod 42 has a positive thread section and a negative thread section. The positive thread section passes through one of the sliding blocks 43 and is assembled with a threaded transmission. The negative thread section passes through the other sliding block 43 and is assembled with a threaded transmission. The barrier servo motor 41 is installed on the beam 2 and is connected to one end of the bidirectional screw rod 42. The bottoms of the two sliding blocks 43 are respectively connected to the tops of the two groups of barrier units 3.

[0033] The servo drive power group 4 designed above has a simple structure, low manufacturing and maintenance costs, stable operation, and can smoothly drive the two groups of barrier units 3 toward or away from each other.

[0034] In order to facilitate the installation and fixation of the servo drive power group 4 and provide a certain degree of protection for the servo drive power group 4, the beam 2 includes a base plate 21 and two side plates 22. The two side plates 22 are vertically fixed to the upper surface of the base plate 21. The two side plates 22 are arranged in parallel, and a strip mounting groove is formed between the two side plates 22. The servo drive power group 4 is located in the strip mounting groove, and the base plate 21 is provided with strip holes for the two sliding blocks 43 to move back and forth.

[0035] In order to avoid rigid contact between the blocking unit 3 and the two sides of the drum brake pad, an elastic connecting seat 5 is provided at the bottom of the blocking unit 3. The elastic connecting seat 5 is elastically connected to the bottom of the sliding block 43 to ensure that the gap between the two groups of blocking units 3 can be adjusted according to the width of the drum brake pad, which has a good protective effect on the drum brake pad.

[0036] Specifically, the elastic connecting seat 5 includes a connecting block 51, a connecting shaft 52 and an adjusting spring 53. The connecting block 51 is fixed to the top of the blocking unit 3. The connecting shaft 52 is vertically connected to the connecting block 51. The axial direction of the connecting shaft 52 is the sliding direction of the blocking unit 3. The bottom of the sliding block 43 is provided with a through hole 431 adapted to the connecting shaft 52. The end of the connecting shaft 52 away from the connecting block 51 is provided with a limiting portion 54. The connecting shaft 52 passes through the adjusting spring 53, and the two ends of the adjusting spring 53 are respectively pressed against the limiting portion 54 and the inner wall of the through hole 431.

[0037] The elastic connecting seat 5 designed as above has a simple structure and is relatively easy to manufacture and assemble, and is conducive to a “soft” connection between the barrier unit 3 and the sliding block 43 .

[0038] In this embodiment, two guide rails 6 are fixed to the lower surface of the crossbeam 2 and arranged along the length of the crossbeam 2. A plurality of guide blocks 7 are fixed to the top of the barrier unit 3, and the guide blocks 7 are slidably assembled with the guide rails 6. This ensures that the barrier unit 3 is more stable and less likely to shake when sliding along the crossbeam 2.

[0039] In this embodiment, the barrier unit 3 includes a horizontally arranged top plate 31 and a vertically arranged barrier plate 32. The barrier plate 32 is vertically connected to the bottom of the top plate 31. A grinding notch 321 for processing a warning line is provided on one side of the barrier plate 32. The barrier unit 3 also includes a reinforcing rib plate 33. The reinforcing rib plate 33 is vertically connected to the barrier plate 32 and the top plate 31. The top plate 31 and the reinforcing rib plate 33 are located on the side of the barrier plate 32 away from the gap.

[0040] The blocking unit 3 designed above has a simple and strong structure and a low manufacturing cost. It has a better blocking effect on the drum brake pad during the process of the drum brake pad being rotated and conveyed on the roller mold.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
