[0016] The suspension brake structure of the present utility model is described below in conjunction with the accompanying drawings.

[0017] In the first embodiment of the present application, Figure 1 and Figure 2As shown, the present suspension brake structure (hereinafter referred to as "this patent") comprises a foot brake elbow 1, a front brake rod 2, a frame 3, a return spring 4, a brake distribution shaft 5, a roller seat 6, a brake cable 7, a rear axle brake drum 8, a roller seat housing 9, a roller 10, a plug 11 and a control rocker arm 12. The foot brake elbow 1 is installed at the front of the frame 3. The foot brake elbow 1 is connected to the brake force distribution component through the front brake rod 2. The brake force distribution component is connected to the rear axle brake drum 8 through the brake cable 7. The power distribution assembly also includes a brake distribution shaft 5 and a roller seat 6. The front brake rod 2 is connected to one end of the control rocker arm 12, and the other end of the control rocker arm 12 is fixedly connected to the brake distribution shaft 5. The brake distribution shaft 5 is installed on the lower surface of the frame 3 through three or four roller seats 6. The two ends of the brake distribution shaft 5 are respectively connected to the brake cable 7 through the control rocker arm 12, and the end of the brake cable 7 is connected to the rear axle brake drum 8. The control rocker arm 12 connected to the front brake rod 2 is installed with a return spring 4, and the return spring 4 is hinged to the frame 3.

[0018] The utility model number of the pedal-type tricycle rear wheel brake system is CN206107474U (hereinafter referred to as "this patent"). The brake force distribution shaft of this application is fixed by welding through a connecting plate. In actual use, it is very easy to deform and jam the brake distribution shaft, affecting the safety of the vehicle. This patent uses a sturdy roller seat 6 as an installation component of the brake distribution shaft 5, which can effectively improve the operation reliability of the brake distribution shaft 5 and ensure stable and reliable braking action.

[0019] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 3 As shown, the roller seat 6 includes a roller seat shell 9, rollers 10 and seals 11. The brake distribution shaft 5 passes through a through hole opened at the center of the roller seat shell 9. A roller 10 is provided between the brake distribution shaft 5 and the roller seat shell 9. Seals 11 with through holes are provided on both sides of the roller seat shell 9 which is sleeved in the middle of the brake distribution shaft 5. The seals 11 on the outside of the roller seat shell 9 at both ends of the brake distribution shaft 5 have no through holes.

[0020] In order to further optimize the working efficiency of the present application and to make the rebound more stable, the return spring 4 is a hydraulic spring. In order to allow the brake cable 7 to be stably arranged on the lower surface of the frame 3, the brake cable 7 is equipped with a fixing pin on the outside. In order to make the braking force controllable and leave a small amount of deformation margin for the control rocker arm 12, the front brake rod 2 is a retractable sleeve structure, and the length of the front brake rod 2 is controlled by a screw.

[0021] When in use, install the suspended brake structure and the equipment can be put into use.

[0022] When the utility model is in use, the specific operations are as follows:

[0023] When braking, the driver steps on the foot brake bend 1, and the foot brake bend 1 drives the front brake rod 2 to move forward. The front brake rod 2 drives the brake distribution shaft 5 installed in the roller seat 6 to roll with itself as the center through a control rocker arm 12. The rolling brake distribution shaft 5 drives the control rocker arms 12 at both ends to flip forward, and then pulls the brake cable 7 and the rear axle brake drum 8 to brake. When braking, the return spring 4 is in a stretched state. After the driver releases the foot brake bend 1, the front brake rod 2, the brake distribution shaft 5, the brake cable 7 and the rear axle brake drum 8 are reset under the action of the return spring 4.

[0024] In summary, the suspended brake structure of the embodiment of the utility model effectively improves the stability of the brake distribution shaft 5 during operation by replacing the original connecting plate with the roller seat 6 and taking advantage of the relatively solid structure of the roller seat 6 itself, thereby ensuring the long-term stable use of the brake force distribution shaft and effectively improving driving safety.
