[0008] In an exemplary embodiment of the present disclosure, the second wire harness has multiple fixing points on the bottom surface of the frame, and the maximum spacing between the fixing points of the second wire harness on the bottom surface of the frame is no greater than the maximum spacing between the fixing points of the wire harness on the side surface of the frame.

[0009] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: arranging a third wire harness along a vertical side of a vehicle frame, with the angle between the third wire harness and a horizontal plane being 75°-105°.

[0010] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: arranging a fourth wire harness along the front-to-rear direction of a longitudinal beam of a frame, the fourth wire harness avoiding the top surface of the longitudinal beam of the frame; the number of the fourth wire harness on the inner side surface of the longitudinal beam of the frame is greater than the number on the outer side surface of the longitudinal beam of the frame; and the number of the fourth wire harness on the upper part of the longitudinal beam of the frame is greater than the number on the lower part of the longitudinal beam of the frame.

[0011] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: providing a corrugated protective tube outside a wire harness located below a centerline of a longitudinal beam of a vehicle frame.

[0012] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: fixing a fifth wire harness between a steering knuckle and a steering control arm, wherein a fixing point M3 of the fifth wire harness on the steering knuckle is located on the side of the steering knuckle top closest to the vehicle frame.

[0013] In an exemplary embodiment of the present disclosure, the fixing point of the fifth wiring harness on the steering control arm is M4, and the portion of the fifth wiring harness between the fixing point M3 and the fixing point M4 is parallel to the vertical plane; and / or, the fixing point M4 of the fifth wiring harness on the steering control arm is located at the edge protrusion of the steering control arm, and the portion of the fifth wiring harness between the fixing point M3 and the fixing point M4 does not contact the steering control arm when it swings.

The turning radius R1 of the wiring harness between the first and second sides is increased by 0.5 to 0.8 times compared to the static bending radius R2. This prevents the wiring harness from increasing its dynamic bending radius in practical environments, such as low temperatures, which could lead to excessive tension during harness swinging and insulation stripping in the bend area, shortening the harness lifespan, or failing to meet vehicle wiring requirements.

[0027] Furthermore, in this application, directional terms such as "upper" and "lower" are used solely to indicate relative positions.

[0028] Mining dump trucks generally refer to mechanical or electric drive mining dump trucks with a tonnage of more than 100 tons, and electric drive mining dump trucks are mainstream mining truck products. Their electrical equipment includes main generators, traction motors, converter cabinets, resistor cabinets, controllers, display screens, light signal equipment, various switches, relays, sensors and solenoid valves, etc. There are many types and quantities of electrical equipment, and the layout of wiring harnesses and cables is large, which leads to many electrical faults. Among them, electrical faults caused by line faults in operating vehicles are the most common, and it is particularly important to analyze the causes of electrical faults. Figure 1 As shown, a schematic diagram of a vehicle wiring harness installed on a vehicle frame 1 is shown. The main components of the vehicle frame 1 may include a longitudinal beam 11, a rear tail beam 12, an axle housing 13, a cross beam 14, a bumper 15, a mounting platform 16, etc.

[0029] In typical electrical design, environmental factors generally only consider ambient temperature, and selecting a wiring harness that adapts to this ambient temperature can meet the design requirements of mining dump trucks. However, mining dump trucks are used in harsh environments, have complex structures, and are in constant motion. Conventional wiring methods are difficult to adapt to the characteristics of the vehicle structure and operating conditions, resulting in problems such as easy breakage and fracture, water corrosion, and a short service life for mining dump truck wiring harnesses.

[0030] In response to the above problems, the present disclosure provides a wiring method for a mining dump truck, which is used to lay out the wiring harness of the mining dump truck. The wiring method for the mining dump truck includes:

[0031] The first wiring harness is arranged along the first side surface and the second side surface, where the first side surface and the second side surface are two adjacent surfaces perpendicular to each other on the vehicle frame 1; the first wiring harness has at least one fixing point on the first side surface, and the first wiring harness has at least one fixing point on the second side surface; a ratio R1 / R2 of a turning radius R1 of the first wiring harness between the first side surface and the second side surface to a static bending radius R2 of the first wiring harness satisfies 1.5≤R1 / R2≤1.8.

[0032] In the wiring method for a mining dump truck disclosed herein, when the wiring harness is arranged on two adjacent, perpendicular surfaces of the vehicle frame 1, fixing points are provided on both sides to prevent the wiring harness from long-term swinging on the vehicle frame 1 and wear caused by bumps and shaking during driving. The turning radius R1 of the wiring harness between the first side and the second side is increased by 0.5 to 0.8 times compared to the static bending radius R2. This prevents the wiring harness from increasing its dynamic bending radius in actual environments, such as low temperatures, which can lead to excessive tension during wiring harness swinging, causing the insulation layer of the wiring harness to peel off in the bending area, shortening the wiring harness life, or failing to meet the wiring requirements of the entire vehicle.

[0033] For example, reference Figure 2 , shows a bottom view schematic diagram of the left front wheel speed signal line. In the figure, the first side surface and the second side surface can be the inner side surface and the bottom surface of the longitudinal beam 11 of the frame 1, respectively. The wiring harness has at least one fixed point on the first side surface and the second side surface. For example, the wiring harness has a fixed point M1 on the inner side surface of the longitudinal beam 11 and a fixed point M2 on the bottom surface of the longitudinal beam 11. The turning radius R1 of the wiring harness between the first side surface and the second side surface is 1.5 to 1.8 times the static bending radius R2 of the first wiring harness.

[0034] In practice, mining dump trucks operate in harsh environments, such as those in high-altitude areas, where extreme weather, large temperature fluctuations, and strong ultraviolet rays often occur, shortening the service life of cables. In exemplary embodiments of the present disclosure, flexible protective tubes can be added to some or all of the bends in the wiring harness to effectively reduce the probability of insulation stripping.

[0035] Furthermore, it should be noted that the term "two adjacent perpendicular surfaces on the frame 1" as used herein refers to nearly perpendicular adjacent surfaces on the frame 1. For example, the top and side surfaces, the side and bottom surfaces of the longitudinal beam 11, and the top and side surfaces, the side and bottom surfaces of the mounting platform 16 are generally perpendicular adjacent surfaces, and their actual angles may not be a perfect 90°. For example, the term "two adjacent perpendicular surfaces on the frame 1" as used herein may refer to adjacent side surfaces on the frame 1 with an angle between 75° and 105°.

[0036] In an exemplary embodiment of the present disclosure, referring to Figure 2As shown, the first wiring harness's closest fixed point on the first side surface to the second side surface is M1; the first wiring harness's closest fixed point on the second side surface to the first side surface is M2. The ratio (L / R2) of the first wiring harness's distance L between M1 and M2 to the first wiring harness's static bending radius R2 satisfies 2≤L / R2≤3. When the wiring harness is routed along mutually perpendicular walls on the vehicle frame 1, the first wiring harness's distance L between M1 and M2 is increased by 1 to 2 times relative to the first wiring harness's static bending radius R2. This allows for dynamic bending margin in the wiring harness while preventing excessive swing and wear of the wiring harness when the mining dump truck is operating in harsh conditions.

[0037] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: arranging a second wiring harness in a first mounting area on the bottom surface of the vehicle frame 1, where the first mounting area coincides with the projection of the mounting location of the vehicle hydraulic equipment and / or filter equipment on the bottom surface of the vehicle frame 1. For areas on the vehicle frame 1 where the vehicle hydraulic equipment and / or filter equipment are mounted, the wiring harness passing through this area is arranged on the bottom surface of the vehicle frame 1. This helps prevent corrosion of the wiring harness passing through this area by the liquid working fluid in the vehicle hydraulic equipment and / or filter equipment. Arranging the second wiring harness in the first mounting area on the bottom surface of the vehicle frame 1 minimizes contact with the liquid working fluid in the hydraulic equipment and / or filter equipment.

[0038] Exemplarily, the second wiring harness may have multiple fixing points on the bottom surface of the vehicle frame 1, and the maximum spacing between the fixing points of the second wiring harness on the bottom surface of the vehicle frame 1 is no greater than the maximum spacing between the fixing points of the wiring harness on the side surface of the vehicle frame 1. When arranging the wiring harness on the bottom surface of the vehicle frame 1, setting multiple fixing points is helpful in preventing the wiring harness from swinging on the bottom surface of the vehicle frame 1. Mining dump trucks usually work in plateau mining areas where the weather is changeable, with abundant wind, snow and rain. The roads on which mining dump trucks travel are muddy and full of water. It is common for the wheels to sink into deep pits of about one meter. The mud and water splashed onto the vehicle frame 1 are rich in various sands, gravels and corrosive substances. The fixed spacing between the fixing points of the second wiring harness on the bottom surface of the vehicle frame 1 is relatively small, which is helpful in preventing the wiring harness from sinking into mud and water, or coming into contact with obstacles on the road.

[0039] In an exemplary embodiment of the present disclosure, the wiring method for a mining dump truck includes: arranging the third wire harness along the vertical side of the frame 1, and the angle between the third wire harness and the horizontal plane is 75°-105°. For example, referring to Figure 2 、 Figure 3 as well as Figure 4 As shown, the third harness is arranged along the side of the longitudinal beam 11. Figure 3 A top view diagram, Figure 4In order to observe the horizontal view of the longitudinal beam 11 horizontally from the inner side of the longitudinal beam 11, when the wiring harness is arranged along the vertical side of the frame 1, the third wiring harness is made perpendicular to the horizontal plane as much as possible. This can facilitate the muddy water splashed onto the wiring harness and the liquid dripping from the hydraulic components, filters and other components on the vehicle to drip quickly under the action of their own weight, reducing the adhesion time of the liquid on the wiring harness and reducing the corrosion of the wiring harness.

[0040] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: arranging a fourth wiring harness along the front-to-back direction of the longitudinal beam 11 of the vehicle frame 1. For example, based on the vehicle coordinate system, the front-to-back direction of the vehicle frame 1 is the vehicle X direction, the left-to-right direction is the vehicle Y direction, and the up-down direction is the vehicle Z direction. The fourth wiring harness is arranged to avoid the top surface of the longitudinal beam 11 of the vehicle frame 1. For example, when arranging the wiring harness in the front-to-back direction, the wiring harness is arranged as close to the upper side of the longitudinal beam 11 as possible, referring to Figure 3 As shown, on the one hand, it is beneficial to avoid squeezing the wiring harness when installing other vehicle body structures on the top of the longitudinal beam 11, and to avoid vehicle assembly workers stepping on the wiring harness during the assembly process, causing damage to the wiring harness; on the other hand, it is also beneficial to avoid corrosion of the wiring harness by accumulated water.

[0041] For example, the number of fourth wiring harnesses on the inner side of the longitudinal beam 11 is greater than that on the outer side. During driving, the longitudinal beam 11 shields the fourth wiring harness from direct ultraviolet radiation, reducing the likelihood of insulation stripping. The number of fourth wiring harnesses on the upper portion of the longitudinal beam 11 can be greater than that on the lower portion to prevent splashing of mud and water and ensure cleanliness. Furthermore, the fourth wiring harness can be arranged on the underside of the platform of the vehicle frame 1 to protect it from direct ultraviolet radiation.

[0042] In addition, a corrugated protective tube can be installed outside the wiring harness below the center line of the longitudinal beam 11. The end surface of the corrugated protective tube and the exposed wiring harness can be heat-shrunk with a heat shrink hose, and the heat shrinkage should be extended as far as possible to the equipment lead position to provide all-round protection for the wiring harness.

[0043] In an exemplary embodiment of the present disclosure, a wiring method for a mining dump truck includes: fixing the fifth wiring harness between the steering knuckle 21 and the steering control arm 22, wherein the fixing point M3 of the fifth wiring harness on the steering knuckle 21 is located on the side of the top of the steering knuckle 21 closest to the vehicle frame 1. Figure 5As shown, the mining dump truck is in a state of motion for a long time, and the front wheel steering knuckle 21 and the steering control arm 22 are components that frequently move relative to each other. The steering knuckle 21 is a cylindrical casting, which is installed at one end of the steering control arm 22. The highest plane of the steering knuckle 21 is about 300 to 500 mm higher than the steering control arm 22. The front wheel shaft temperature sensor and speed sensor are installed at a position slightly higher than the steering knuckle 21, and their wiring harness installation path passes through the steering knuckle 21, the steering control arm 22 and the frame 1. The fifth wiring harness between the steering knuckle 21 and the steering control arm 22 is a suspended wiring harness. How the steering knuckle 21 and the steering control arm 22 are installed is related to the length and swing amplitude of the wiring harness. For different models, the span of the wiring harness is inconsistent, and long-term swinging can easily cause the wiring harness to break, causing electrical failure.

[0044] In this exemplary embodiment, the fixing point of the fifth wiring harness on the steering knuckle 21 is arranged on the side of the top of the steering knuckle 21 closest to the vehicle frame 1. During the dynamic process of the wheel turning angle, this fixing point M3 can make the designed wiring harness length the shortest, the swing amplitude of the wiring harness the smallest, and the wiring harness length requirement the lowest.

[0045] Illustratively, the fixing point of the fifth wire harness on the steering control arm 22 is M4 , and the portion of the fifth wire harness between the fixing point M3 and the fixing point M4 is parallel to the vertical plane, which is beneficial to further reduce the designed wire harness length.

[0046] In another exemplary embodiment of the present disclosure, referring to Figure 5 As shown, the fixing point M4 of the fifth wiring harness on the steering control arm 22 is located at the edge protrusion of the steering control arm 22, and the fifth wiring harness does not contact the steering control arm 22 when it swings partially between the fixing point M3 and the fixing point M4. According to the analysis of the faulty vehicle, the area prone to wiring harness breakage is the wiring harness fixing point between the steering knuckle 21 and the steering control arm 22. In this embodiment, the wiring harness length can be calculated based on the wiring harness swing amplitude, and the wiring harness swing can be simulated based on the wiring harness length and the dynamic bending radius of the wiring harness so that the swing does not come into contact with the steering control arm 22. After comprehensive consideration, the wiring harness is fixed at the position fixing point M4 of the steering control arm 22, thereby reducing the probability of wiring harness breakage failure. For example, the present disclosure fixes the wiring harness to the vehicle body, such as fixing it to the frame 1 or the steering knuckle 21, the steering control arm 22, etc., and can be fixed using an R-type pipe clamp with a soft rubber lining.

[0047] It should be noted that the present disclosure uses nomenclature such as "first wiring harness", "second wiring harness", and "third wiring harness" to refer to the method of arranging wiring harnesses in different areas on the vehicle frame 1. The actual meanings of wiring harnesses such as "first wiring harness", "second wiring harness", and "third wiring harness" can be determined based on the specific wiring harnesses arranged on the vehicle frame 1, such as hydraulic oil tank sensor signal lines, wheel speed signal lines, main generator control lines, and the like. In addition, in some embodiments, the same wiring harness may exist in the "first wiring harness", "second wiring harness", and "third wiring harness". For example, the same wiring harness may be referred to as the "first wiring harness" in this application when it is bent and arranged between the first side surface and the second side surface; it may be referred to as the "second wiring harness" in this application when it is arranged in the first installation area on the bottom surface of the vehicle frame 1; it may be referred to as the "third wiring harness" when it is arranged along the vertical side surface of the vehicle frame 1; and it may be referred to as the "fourth wiring harness" when it is arranged along the front-to-back direction of the frame longitudinal beam 11.

[0048] According to another aspect of the present disclosure, a mining dump truck is provided, comprising a vehicle frame, vehicle equipment, and a wiring harness. The wiring harness connects the various vehicle equipment components and is fixed to the vehicle frame 1. The wiring harness is routed according to any of the aforementioned wiring methods for mining dump trucks. The mining dump truck disclosed herein can reduce the risk of vehicle wiring harness wear and extend its lifespan, thereby reducing maintenance cycles and costs and improving the operational reliability of the mining dump truck.
