DETAILED DESCRIPTION

[0017] The utility model will be further explained in detail below in combination with the drawings and specific embodiments.

[0018] As Figure 1 shown, a full disc wheel edge brake device, including with the hub 1 coaxial fixed guide limit ring 2, guide limit ring 2 outer along the axial sliding sleeve joint has brake disc 3, brake disc 3 outside is provided with brake control assembly,

[0019] As Figures 1-3 shown, the brake control assembly includes the box shell 4 fixed on the frame, the box shell 4 end corresponds fixed cover plate 5, the box shell 4 inside coaxial rotation is connected with control ring 6, control ring 6 is close to the end of cover plate 5 along the circumferential even open multiple ramp groove 7, cover plate 5 is along the circumferential even open multiple installation through mouth 8, installation through mouth 8 with ramp groove 7 one to one correspondence, cover plate 5 one side from near to far is provided with push frame 9 and connecting frame 10, the brake disc 3 is between push frame 9 and connecting frame 10, push frame 9 close to the side of brake disc 3 along the circumferential even fixed multiple first brake block 11, connecting frame 10 close to the side of brake disc 3 along the circumferential even fixed multiple second brake block 12, first brake block 11 with second brake block 12 one to one correspondence, connecting frame 10 outside along the circumferential even fixed multiple lug plate 13, lug plate 13 all with cover plate 5 fixed, lug plate 13 all slidingly fit in push frame 9 outside, push frame 9 is along the circumferential even fixed multiple push force seat 14, push force seat 14 one to one correspondence slidingly passes through the installation through mouth 8, push force seat 14 is rotationally connected with guide bearing 15, guide bearing 15 with the slope face of ramp groove 7 one to one correspondence rolls, the box shell 4 and push frame 9 are connected with reset tension spring 16, control ring 6 is driven by drive assembly.

[0020] Before braking, through the connection of guide limit ring 2, hub 1 rotates with brake disc 3, brake disc 3 is separated from push frame 9 and connecting frame 10 at this time, first brake block 11 and second brake block 12 do not constitute the clamping effect to brake disc 3.

[0021] When braking, drive assembly drives control ring 6 to rotate, the position of ramp groove 7 slope on control ring 6 changes, push force seat 14 moves push frame 9 towards brake disc 3, push frame 9 approaches connecting frame 10, finally makes first brake block 11 and second brake block 12 clamp lock brake disc 3, that is, realizes the braking effect to hub 1.In the above process, when ramp groove 7 pushes push force seat 14 to move, through the rolling contact of guide bearing 15 with the slope face of ramp groove 7, the friction can be reduced, and the durability can be improved.

[0022] When braking is completed, brake action is released, drive assembly drives control ring 6 to rotate, reset tension spring 16 pulls push frame 9 away from connecting frame 10, that is, the clamping state of brake disc 3 is released, and hub 1 can drive again.

[0023] In the technical solution, the brake disc 3 is clamped by the plurality of corresponding first brake blocks 11 and second brake blocks 12 arranged in the circumferential direction, so that the brake of the wheel hub 1 is realized. Compared with the structure of the drum brake device which is overall closed and not easy to dissipate heat, the push frame 9, the connecting frame 10, the first brake block 11 and the second brake block 12 and other brake action components of the device are all exposed to the outside, so that the heat dissipation effect is significantly improved.

Since the gear shaft 18 is driven to rotate to provide the braking force, the greater braking force can be conveniently provided in the technical solution, for example, the driver can adopt a cylinder force increasing mechanism, so that the braking force far exceeding that of the traditional brake can be provided, thereby making the braking effect more prominent.

[0026] As shown in Figures 1-3 The ear plate 13 is provided with a guide groove 19, the direction of the guide groove 19 is parallel to the axial direction of the brake disc 3, the side of the push frame 9 is uniformly provided with a plurality of guide shafts 20 in the circumferential direction, and the guide shafts 20 are in sliding connection with the guide grooves 19 one by one.
