The brake arm is connected to the brake block through a pin shaft, and the top plate is fixedly installed under the brake arm by bolts, and the lower end of the brake arm is hinged to the support through a pin shaft; an adjusting bolt and an adjusting nut are installed at the protruding end of the top plate, and the adjusting nut is used to make it contact with the support under pressure, and the adjusting bolt is fixedly installed on the top plate. Effects of the present invention: reasonable structure, low cost, easy installation and use, safe and reliable, greatly reducing the amount of maintenance during work and improving work efficiency. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] The existing brake disc pull arm often generates a lot of heat after the vehicle brake friction, which is difficult to dissipate. Long-term work can easily make the brake disc pull arm temperature too high, thus affecting the braking effect. Secondly, the brake disc pull arm at this stage often does not have a reinforced structure. If the pull arm strength is not enough, it is easy to cause the pull arm to deform when subjected to force, and then cause the pull wire stroke to be lengthened, affecting the braking effect;

[0005] Therefore, in view of the above problems, a kind of automobile brake disc pulling arm structure is proposed. Utility Model Content

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details:

[0027] As a preferred embodiment, a limit ring 9 is provided at one end of the brake disc pull arm 1 away from the connecting hole 2, and two sets of limit rings 9 are penetrated by adjusting screws 10; further, the limit rings 9 play a limiting role, and the adjusting screw 10 can move within the limit rings 9.

[0028] As a preferred embodiment, the end of the adjusting screw 10 passes through the two groups of limiting rings 9 and is threadedly connected with an adjusting nut 11. The middle outer wall of the adjusting screw 10 is sleeved with a spring 12, and the two ends of the spring 12 are respectively abutted against the two groups of limiting rings 9; further, the distance between the two groups of limiting rings 9 can be adjusted by twisting the adjusting nut 11, thereby facilitating the adjustment of the position of the brake disc pull arm 1 for stable braking, and the spring 12 is compressed, shrinks and rebounds to play a certain supporting and limiting role.

[0029] As a preferred embodiment, the middle parts of the two sets of brake disc pull arms 1 are connected by a reset spring 13; further, the reset spring 13 plays a reset role. When the brake disc pull arm 1 is pushed to translate outward so that the friction plate 15 contacts the brake drum 16, the brake disc pull arms 1 on both sides can be pulled inward by the reset spring 13 when the brake is canceled after the vehicle is braked, thereby achieving the reset effect.

[0030] As a preferred embodiment, the inner wall of the brake disc arm 1 is welded with a reinforcing rib 14, and the reinforcing rib 14 is made of a high-strength metal material; further, the reinforcing rib 14 plays a reinforcing role to prevent the brake disc arm 1 from being deformed due to the arm force, thereby affecting the braking effect.

[0032] The working process of the utility model is as follows: the brake disc arm 1 is pushed to translate outward through the brake wheel cylinder 3 so that the friction plate 15 contacts the brake drum 16, thereby achieving the braking of the vehicle. The heat conducting plate 4 plays a heat conducting role and can absorb and conduct the heat generated by the operation of the brake disc arm 1. The coolant is arranged in the coolant tank 6. The micro pump 8 can pump the coolant in the coolant tank 6 into the cooling elbow 5 through the connecting hose 7. The coolant circulates in the cooling elbow 5 and then flows back to the coolant tank 6. The cooling elbow 5 is close to the heat conducting plate 4 so that the coolant circulates in the cooling elbow 5 to take away the heat conducted by the heat conducting plate 4, thereby playing a role in cooling the brake disc arm 1, and avoiding the brake disc arm 1 from being overheated.
