Description

Technical Field

[0001] This utility model relates to the field of mechanical disc brakes, and in particular to a polymer heavy-duty mechanical disc brake. Background Technology

[0002] In vehicle braking systems, the heavy-duty polymer mechanical disc is a key actuator, and the reliability of its brake cable fixation directly affects the braking response accuracy and driving safety. In traditional mechanical disc structures, the brake cable is usually fixed only through the pass-through part on the side of the limiting block, i.e., the opening slot.

[0003] However, the continuous vibration generated during vehicle operation can cause the friction between the brake cable and the limit block to gradually weaken. After long-term service, the cable is prone to loosening from the gap in the passage, causing the brake cable to loosen. The single slot only provides linear constraint and lacks effective restriction on the radial displacement of the cable. Especially during emergency braking or severe bumps, the cable is prone to deflection due to inertial force or even jump out of the slot.

[0004] Therefore, how to achieve multiple limiting and fixing of the brake cable, thereby reducing the possibility of the brake cable coming off at the pass-through point due to driving vibration after long-term use, has become a technical problem that urgently needs to be solved in the field of heavy-duty polymer mechanical disc brakes.

[0032] Example 1: This utility model provides the following... Figure 1-5 The polymer heavy-duty mechanical disc shown includes: a mechanical disc body 1, a fixing component and a limiting component;

[0033] It should be noted that the fixing components are symmetrically arranged on the side of the mechanical disc body 1. The fixing components are used for the installation and fixing of the mechanical disc body 1, and the limiting components are used for limiting the insertion of the brake cable.

[0034] Specifically, the working principle of the mechanical disc body 1 is based on the working principle of the S-6 cable-operated disc brake caliper. It performs brake clamping operation through the brake cable and is made of polymer material, which has the function of heavy-load braking.

[0035] The limiting component includes a limiting block 3 disposed on the side of the mechanical disc body 1. The side of the limiting block 3 has a through portion for the brake cable to pass through. The side of the limiting block 3 is connected to a limiting part for reinforcing and fixing the position of the brake cable. The side of the limiting part has a protrusion for assisting the rotation of the limiting part.

[0036] It should be noted that the through part includes: through hole 301 and wire groove 302;

[0037] Specifically, the through hole 301 is opened on the side of the limiting block 3 and is used to limit the brake cable. The wire groove 302 is opened on the inner wall of the through hole 301 and is used to assist the brake cable in entering the through hole 301.

[0038] It should be noted that the brake cable enters the through hole 301 through the cable groove 302, thereby limiting the brake cable.

[0039] Specifically, the limiting part includes a threaded open ring sleeve 4, the end of which is threadedly connected to the middle of the through hole 301. The threaded open ring sleeve 4 is used to prevent the brake cable from coming out of the through hole 301.

[0040] It should be noted that a threaded groove 303 is provided on the inner wall of the hole 301. The threaded groove 303 is used for the threaded insertion of the threaded open ring 4. The outer side of the threaded open ring 4 is provided with threads, and a notch is provided on its side for the brake cable to pass through. The notch does not affect the engagement of the threads. The brake cable enters the inner cavity of the threaded open ring 4 and the hole 301 through the notch and the wire groove 302 at the same time. Then, the threaded open ring 4 is rotated to make the notch and the wire groove 302 misaligned, thereby constraining and fixing the brake cable.

[0041] Specifically, the protrusion includes: a hexagonal retaining ring 5 and an opening groove 501;

[0042] It should be noted that the hexagonal retaining ring 5 is located at the end of the threaded open ring sleeve 4 away from the limiting block 3, and the opening groove 501 is opened on the side of the hexagonal retaining ring 5. The opening groove 501 is used for the insertion of the brake cable.

[0043] Specifically, the hexagonal fixing ring 5 is welded and fixed to the threaded open ring sleeve 4. A rotating bar 7 is provided on the side of the hexagonal fixing ring 5. The rotating bar 7 is used to hold and rotate the rotating bar 7. A friction sleeve 6 is provided on the inner wall of the hexagonal fixing ring 5 and the threaded open ring sleeve 4. The friction sleeve 6 is used to isolate the brake cable from the inner wall of the threaded open ring sleeve 4 and the hexagonal fixing ring 5.

[0044] It should be noted that the rotating bar 7 is welded and fixed to the hexagonal fixed ring 5, the friction sleeve 6 is made of rubber, and it is glued and fixed to the inner wall of the threaded open ring sleeve 4 and the hexagonal fixed ring 5. The rotating bar 7 is used to increase the rotational power arm of the hexagonal fixed ring 5 and assist the rotation of the hexagonal fixed ring 5.

[0045] Example 2: A fixing component applied to the polymer heavy-duty mechanical disc in Example 1.

[0046] Specifically, the fixing components include: a fixing plate 2 and mounting holes 201;

[0047] It should be noted that multiple fixing plates 2 are symmetrically arranged on the side of the mechanical disc body 1, and mounting holes 201 are opened on the side of the fixing plates 2. The mounting holes 201 are used for mounting and fixing the mechanical disc body 1 to the frame.

[0048] Specifically, the fixing plate 2 and the mechanical disc body 1 are fixed by welding, and the mounting hole 201 is used for mounting bolts to be inserted and fixed.

[0049] In actual use, by setting a limiting component on the side of the mechanical disc body 1, the limiting part in the limiting component constrains and limits the brake cable that is limited by the through hole 301 on the side of the limiting block 3. Compared with the existing brake cable which is only limited and fixed by the through hole 301 on the side of the limiting block 3, the limiting part of this design fixes the brake cable a second time, reducing the possibility that the brake cable will come off from the through part due to driving vibration after long-term use.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
