[0028] The embodiment provides a brake line adjusting nut, a brake line 2 is installed on a drum brake 3, comprising:

[0029] The adjusting nut 1 is provided with a nut hexagonal head 12 at one end and a rod end at the other end. One end of the nut hexagonal head 12 faces the outgoing end of the brake line 2 installed in the drum brake 3.

[0030] In some embodiments of the present application, the adjusting nut 1 comprises:

[0031] The through hole 11 is provided with the brake line 2.

[0032] In some embodiments of the present application, the through hole 11 comprises a first end face 111 and a second end face 112, and the second end face 112 is a threaded surface.

[0033] Specifically, the second end face 112 is a threaded surface, which is used to cooperate with the outer tube or inner line of the brake line 2, and the effective length of the brake line 2 is adjusted by rotating the nut.

[0034] In some embodiments of the present application, the length of the first end face 111 is L1, the length of the second end face 112 is L2, and The ratio of L1 to L2 is .

[0035] Specifically, the ratio of the two is optimized. The specific ratio can be adjusted according to the actual application requirements to ensure the stability and response speed of the brake line 2 in different working states.

[0036] In some embodiments of the present application, the adjusting nut 1 further comprises:

[0037] The slot is arranged on one side of the rod end, and the radius of the slot is R, and R=L1+L2.

[0038] Specifically, the slot is arranged on one side of the rod end, which increases the mechanical strength of the nut and provides additional anti-loosening function. The radius of the slot not only enhances the fatigue resistance of the nut, but also makes the nut more stable when rotating, preventing loosening due to vibration.

[0039] In some embodiments of the present application, the thickness of the nut hexagonal head 12 is L3, and The ratio of L3 to L2 is 1.

[0040] Specifically, the ratio of the thickness of the nut hexagonal head 12 to the length of the through hole 11 is 1:1, making the nut more convenient to install and adjust. The design of the hexagonal head makes it more stable when adjusting with tools such as wrenches, reducing the risk of slipping and improving work efficiency.

[0041] In some embodiments of the present application, the diagonal length of the nut hexagonal head 12 is K1, the diameter of the inscribed circle of the nut hexagonal head 12 is K2, and the nominal diameter of the thread of the nut hexagonal head 12 is K3, wherein K1:K2:K3:R=81:70:43:40.

[0042] Specifically, in order to ensure the durability and reliability of the nut, it is recommended to use high-strength, corrosion-resistant materials such as stainless steel or alloy steel. These materials have good mechanical properties and fatigue resistance, and can maintain stable tension over a long period of use, reducing the risk of fatigue fracture.

[0043] In addition, in order to improve the corrosion resistance and aesthetics of the nut, galvanizing, chromium plating or other corrosion prevention treatment can be performed on the surface.

[0044] In summary, the installation steps of the adjusting nut 1 are as follows:

[0045] Pass the brake line 2 from the drum brake 3 through the through hole 11 of the adjusting nut 1;

[0046] Ensure that the brake line 2 passes through the first end surface 111 and the second end surface 112 of the through hole 11, and the outer tube or inner wire of the brake line 2 cooperates with the threaded surface;

[0047] Tighten the nut hex head 12 with a wrench, ensuring the brake line 2 has moderate tension;

[0048] Check if the slot aligns with the outer tube or inner line of the brake line 2, ensuring the nut does not loosen due to vibration.

[0049] In summary, the adjustment steps for the adjusting nut 1 are:

[0050] Regularly check the tension of the brake line 2 according to the wear of the brake pads;

[0051] If the brake line 2 is too loose, rotate the nut hex head 12 clockwise to increase the tension of the brake line 2;

[0052] If the brake line 2 is too tight, rotate the nut hex head 12 counterclockwise to loosen the tension of the brake line 2;

[0053] After adjustment, recheck the response of the brake pedal to ensure that the performance of the brake system meets safety requirements.

[0054] Compared with the prior art, the beneficial effects of the embodiment are:

[0055] The brake line 2 passes through the through hole 11 of the adjusting nut 1, ensuring smooth passage of the brake line 2. The first end face 111 and the second end face 112 of the through hole 11 are designed as smooth surfaces and threaded surfaces respectively, allowing the brake line 2 to have a certain space for movement during installation, while effectively fixing and adjusting the tension of the brake line 2 through the threaded surface.

[0056] The ratio of the length L1 of the first end face 111 to the length L2 of the second end face 112 is optimized to ensure the stability and response speed of the brake line 2 in different working states. This design can effectively prevent the brake line 2 from failing due to excessive stretching or compression during use.

[0057] The radius R = L1 + L2 of the slot enhances the mechanical strength of the nut.

[0058] In addition, through the optimized design of the through hole 11 and the length ratio of the threaded surface, the brake line adjusting nut can more accurately adjust the tension of the brake line 2, compensate for the wear of the brake pads, and maintain the response sensitivity of the brake pedal. The slot design and reasonable length ratio make the nut less likely to loosen during vehicle operation, ensuring the stability of the brake line 2 tension and improving driving safety. The hex head design and the presence of the slot make the nut more convenient and fast to install and adjust, reducing maintenance time and cost. High-strength materials and precision machining ensure the mechanical strength and fatigue resistance of the nut, prolonging its service life and reducing maintenance frequency.

[0059] Those skilled in the art can understand that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
