Technical Field

[0001] This utility model relates to the field of front and rear axle technology for commercial vehicles, specifically to an integrated structure of a brake pad wear alarm line and ABS wiring harness for commercial vehicles. Background Technology

[0002] Currently, commercial vehicles with a gross vehicle weight of 3.5T or more must be equipped with brake pad wear warning devices and ABS, and these two systems are installed independently. The brake pad wear warning devices and ABS on the axle are provided by the axle manufacturer. To improve versatility, the wiring harnesses are left too long, causing difficulties in bundling and resulting in messy routing. The brake pad wear warning wires and ABS wires on the chassis are designed by the vehicle manufacturer. The two wires on the chassis are ultimately connected to the two wires on the axle via connectors. To improve versatility, both the axle manufacturer and the OEM have left the wiring harnesses too long, making it difficult to bundle the connected wiring harnesses and resulting in messy routing. This wastes wiring harness length and is also unsightly.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] The following is in conjunction with the appendix Figure 1 , Figure 2 and Figure 3 The embodiments and examples will be described in further detail below. The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0037] Figure 3The diagram shows a wiring structure in the existing technology. The left and right wheel ends of the front and rear axles are connected to four wear alarm wires and four ABS wires inherent to the axles. Correspondingly, four wear alarm wires and four ABS wires designed by the OEM are also connected. In other words, the existing wiring harness structure requires a total of eight wear alarm wires and eight ABS wires, totaling 16 connecting wires, requiring eight connectors. Its disadvantages are: difficulty in bundling the connected wires, messy routing, and high cost.

[0038] like Figure 1 As shown, this utility model embodiment provides an integrated structure of a commercial vehicle brake pad wear warning line and an ABS wiring harness, including: an integrated wiring harness 1 for a first wear warning line and an ABS line, an integrated wiring harness 2 for a second wear warning line and an ABS line, and a plug connector 3.

[0039] The integrated wiring harness 1 of any first wear alarm line and ABS line is a single integrated wiring harness; the integrated wiring harness 2 of any second wear alarm line and ABS line is a single integrated wiring harness.

[0040] Specifically, the wear warning line and ABS line integrated within the axle are separate inside the axle but integrated outside; the wear warning line and ABS line in the chassis design are integrated together into a single line. By integrating the wear warning line and ABS line, the number of wiring harnesses and connectors is reduced, costs are lowered, and assembly is simplified.

[0041] like Figure 1 As shown, the integrated wiring harness 2 for the second wear warning line and the ABS line is provided by the vehicle manufacturer and is located on both sides of the frame 7.

[0042] One end of the integrated wiring harness 2 of any second wear alarm line and ABS line is connected to the chassis wiring harness 6, and the other end is connected to the integrated wiring harness 1 of the first wear alarm line and ABS line through a plug connector 3. The integrated wiring harness 1 of the first wear alarm line and ABS line is integrated into the front axle 4 and the rear axle 5 and is connected to the left and right wheel ends of the front axle 4 and the left and right wheel ends of the rear axle 5, respectively.

[0043] Thus, as Figure 1 As shown, the number of integrated wire harnesses 2 for the second wear alarm line and the ABS line is four.

[0044] The four integrated wiring harnesses 2 for the second wear warning line and the ABS line are arranged symmetrically in pairs. Two of the integrated wiring harnesses are connected to the chassis wiring harnesses 6 on both sides of the frame 7 in the front area, and the other two integrated wiring harnesses are connected to the chassis wiring harnesses 6 on both sides of the frame 7 in the rear area.

[0045] The integrated wiring harness 1 for the first wear warning line and ABS line consists of four wires; plus the four integrated wiring harnesses 2 for the second wear warning line and ABS line, the overall wiring is reduced by half compared to existing technologies. This improves the aesthetics of the arrangement of the brake pad wear warning line and ABS wiring harness in commercial vehicles, reduces the number of wiring harnesses, and lowers costs; it also facilitates wiring harness bundling and improves the aesthetics of the wiring harness layout.

[0046] The four integrated wiring harnesses 1 for the first wear alarm line and the ABS line are arranged symmetrically in pairs. Two of the integrated wiring harnesses are connected to the left and right wheel ends of the front axle 4, and the other two integrated wiring harnesses are connected to the left and right wheel ends of the rear axle 5.

[0047] Correspondingly, such as Figure 1 As shown, only four plug-in connectors are needed, reducing the number of wire harness connectors and lowering costs.

[0048] In an optional embodiment, the plug connector 3 is preferably an AMP plug connector.

[0049] AMP connectors feature insertion direction identification to prevent incorrect insertion.

[0050] Furthermore, such as Figure 3 As shown, the plug-in connector 3 includes a plug-in part 31 and a locking part 32; the plug-in part 31 and the locking part 32 are respectively disposed at the ends of the integrated wire harness 1 of the first wear alarm line and ABS line and the integrated wire harness 2 of the second wear alarm line and ABS line, and the plug-in part 31 is adapted to be plugged into the corresponding locking part 32.

[0051] In summary, compared with the prior art, this embodiment can achieve the following technical effects:

[0052] This utility model embodiment integrates the brake pad wear warning line and ABS wiring harness that are built into the front and rear axles and designed by the OEM into a single wiring harness, reducing the number of wiring harnesses and wiring harness connectors, lowering costs, and making it easier to bundle, while improving the aesthetics of the wiring harness routing.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
