[0002] Wheel speed harness refers to a group of wires and connectors on a car or other vehicle that are used to transmit signals and power to components such as wheel sensors and ABS systems. It is usually installed on the chassis of the vehicle and connected to the wheel sensors and ABS control unit to monitor wheel speed and control the braking system.

[0003] After searching, the announcement number is CN117578148B, which discloses a wiring harness assembly of a vehicle wheel speed sensor, including a wire for transmitting a frequency signal of wheel rotation, and the two ends of the wire harness are respectively connected to the wiring harness connector and the wheel speed connector for connecting the wheel speed sensor through wire crimping terminals; a number of sleeves are sleeved on the outside of the wire, and the sleeves are configured to guide the wire to bend in a specified direction, and a limiting structure is arranged in the sleeve, and the limiting structure is used to stabilize the state of the sleeve; it can not only protect the wire, but also guide the wire to bend in a specified direction when it needs to be bent during the wire laying process, and can stabilize the state of the sleeve without external force, so that the wire laying state is more stable and reduces the occurrence of falling off and entanglement; a number of positioning structures, including a pair of substrates, can quickly and conveniently move the wire or connector to the vehicle body assembly position; the operation is simple and flexible, and when used in conjunction with the above-mentioned sleeve, it can create a stable signal transmission environment for the wire.

[0004] However, the existing wheel speed harness solves the problem of harness fixing and protection, but because the harness is used to connect to the wheel sensor and is installed on the chassis of the vehicle, it is easily disturbed by the road surface, that is, when the road surface is uneven and bumpy or gravel on the road surface is splashed, there will be surface impact or friction on the wheel speed harness, causing damage to the internal wires of the harness, and then causing the vehicle to be unable to receive the status signal of the vehicle tire.

[0005] Therefore, it is necessary to provide a wear-resistant wheel speed harness to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

[0007] Based on the above problems existing in the prior art, the problem to be solved by the present application is to provide a wear-resistant wheel speed harness to solve the problem that the wheel speed harness is not wear-resistant.

[0009] A wear-resistant wheel speed harness comprises a first wear-resistant set and a second wear-resistant set which are sleeved outside the wheel speed harness sleeve, wherein the first wear-resistant set comprises an outer sleeve, a first connecting portion, a first cavity and a first inner sleeve, wherein the inner side of the outer sleeve is integrally formed with the first inner sleeve through a plurality of first connecting portions, and the plurality of first connecting portions respectively surround the outer sleeve and the first inner sleeve to form a plurality of first cavities which play an isolating role;

[0010] The second wear-resistant set comprises a second connecting portion, a second inner sleeve and a second cavity. The inner side of the first inner sleeve is integrally formed with the second inner sleeve through the second connecting portion. A plurality of the second connecting portions, the first inner sleeve and the second inner sleeve respectively form a plurality of second cavities that play an isolating role together;

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0035] See also Figure 1-3 , the utility model provides the embodiment:

[0036] A wear-resistant wheel speed harness comprises a first wear-resistant set 1 and a second wear-resistant set 2 which are sleeved outside a wheel speed harness sleeve 3. The first wear-resistant set 1 comprises an outer sleeve 11, a first connecting portion 12, a first cavity 13 and a first inner sleeve 14. The inner side of the outer sleeve 11 is integrally formed with the first inner sleeve 14 through a plurality of first connecting portions 12. The plurality of first connecting portions 12 respectively surround the outer sleeve 11 and the first inner sleeve 14 to form a plurality of first cavities 13 which play an isolation role.

[0037] The second wear-resistant set 2 includes a second connecting portion 21, a second inner sleeve 22 and a second cavity 23. The inner side of the first inner sleeve 14 is integrally formed with the second inner sleeve 22 through the second connecting portion 21. A plurality of second connecting portions 21, the first inner sleeve 14 and the second inner sleeve 22 respectively form a plurality of second cavities 23 that play an isolation role.

[0038] Among them, multiple first connecting parts 12 are arranged at equal angles and intervals between the outer sleeve 11 and the first inner sleeve 14 with the first inner sleeve 14 as the center, and multiple second connecting parts 21 are arranged at equal angles and intervals between the first inner sleeve 14 and the second inner sleeve 22 with the second inner sleeve 22 as the center.

[0039] Through the multiple first cavities 13 formed by the outer sleeve 11, the first connecting part 12 and the first inner sleeve 14 in the first wear-resistant kit 1, if the outer sleeve 11 of the wheel speed harness is broken or crushed by friction, the internal wheel speed harness sleeve 3 can be prevented from being exposed to the outside under the action of the first inner sleeve 14, thereby achieving a preliminary anti-wear effect.

[0040] In addition, the multiple second cavities 23 formed by the first inner sleeve 14, the second connecting portion 21 and the second inner sleeve 22 can further effectively prevent the first inner sleeve 14 from being damaged. The structure formed by the second cavity 23 can prevent the wheel speed harness sleeve 3 from being damaged when surrounded by the second inner sleeve 22, thereby further improving the wear resistance of the wheel speed harness.

[0041] Among them, multiple first cavities 13 are all in a trapezoidal structure. Through the trapezoidal structure, the closer the first connecting part 12 is to the first inner sleeve 14, the thicker the thickness will be, thereby improving the wear resistance of the first inner sleeve 14, and multiple second connecting parts 21 are in a cylindrical strip shape. Through the cylindrical strip-shaped second connecting part 21, when the first inner sleeve 14 is excessively worn, the second inner sleeve 22 can have better wear resistance under the action of the second connecting part 21 again.

[0042] In order to improve the wear resistance of the outer sleeve 11 , the outer side wall of the outer sleeve 11 is coated with a wear-resistant coating 15 . The wear-resistant coating 15 may be a polyurethane coating, which has good wear resistance and corrosion resistance.

[0043] Furthermore, a foam layer 4 is filled between the outer side of the wheel speed harness sleeve 3 and the second inner sleeve 22, and the foam layer 4 can increase the protectiveness of the wheel speed harness. An aluminum foil 5 is provided on the inner side of the wheel speed harness sleeve 3, and the addition of the aluminum foil 5 can protect the internal wire 8 used for signal transmission from external electromagnetic interference.

[0044] In addition, the wheel speed harness sleeve 3 is equipped with a wire 8 and a support member 7. The wire 8 is located in a cavity formed by the support member 7 and the wheel speed harness sleeve 3. The support member 7 is in a "Y" shape, and the support member 7 can provide better support for the wire 8.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
