[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] Most current wide-body dump trucks are designed for a 90-ton load capacity, using a traditional highway dump truck chassis structure. The chassis is reinforced with riveted frames, leaf spring suspensions, and front and rear axles to increase load capacity, but they lack drive-by-wire functionality. Their drawbacks are that, similar to highway dump trucks, once the load capacity is increased to 90 tons, the overall load-bearing capacity cannot be continuously improved. The mechanical structure is complex, leading to a high failure rate. Due to harsh working conditions, their service life is typically only 3 years, making them unsuitable for the unmanned operation requirements of mining areas.

[0030] like Figures 1-3 As shown, the pure electric drive wire-controlled wide-body dump truck with a carrying capacity of 100 tons provided in this embodiment includes: a frame support system 2, chassis driving systems 1 arranged on both sides of the frame support system 2, an offset cab 10 arranged on the front left side of the frame support system 2, a cargo box 12 arranged on top of the frame support system 2, a braking system 3 arranged in the middle position between the frame support system 2 and the cargo box, the frame support system 2 is a fully welded rigid structure, the braking system 3 adopts a dual redundancy architecture of EBS system, redundant control module and EPB module, a power battery system 4 is arranged on the frame support system 2 between the offset cab 10 and the cargo box 12, a high-voltage power distribution control system 5 is arranged in the middle right position of the offset cab 10, a steering system 6 is arranged on the lower left side of the offset cab 10, a cooling system 7 is arranged at the front of the frame support system 2, and a lifting system 8 is arranged in the right position between the frame support system 2 and the cargo box.

[0031] The chassis load-bearing system 2 is constructed using high-strength Q355D steel, capable of withstanding massive vertical loads and suitable for large open-pit mine ore transportation scenarios. A support plate is installed between the longitudinal beams and cover plates of the chassis load-bearing system 2. This support plate, welded between the longitudinal beams and cover plates, enhances the chassis rigidity, evenly distributes loads under stress, and ensures stability under heavy-load conditions. The chassis exhibits high natural modal characteristics, avoiding road surface and power system excitations, preventing resonance, and demonstrating excellent fatigue resistance. The chassis structure is simple with few parts, facilitating daily maintenance and allowing for easy inspection, repair, and replacement of components by maintenance personnel. The front / rear suspension uses air springs as its core, combined with multi-link (front) and A-frame (rear) structures, with centralized lubrication for component connections, forming a highly efficient suspension system. It boasts advantages such as superior vibration reduction, high safety, strong load-bearing capacity, long maintenance cycles, adaptability to complex road conditions, and rapid dynamic response, comprehensively improving vehicle performance. The overall chassis load-bearing capacity is enhanced, matching a cargo box capable of carrying 100 tons of cargo, extending chassis lifespan by up to 10 years. The cooling system 7 is located at the front of the vehicle to ensure sufficient frontal area and efficient cooling.

[0032] Furthermore, the main body of the braking system 3 is arranged along the inner side of the vehicle frame support system 2 to reduce the risk of environmental impact. The braking system 3 of this invention adopts a dual-redundancy architecture of an EBS system, a redundant control module, and an EPB module, featuring full drive-by-wire control, high-speed CAN, and dual redundancy. It is equipped with a 6s6m ABS system, enabling direct control of all six wheels; a full-function ATC system allows for independent control of slippage in all four drive wheels; and it has brake management functions, coordinating the control of service brakes and motor anti-drag brakes. The braking system 3 includes an oil-free piston air compressor, an air handling unit, and an air tank with a capacity of 190L-210L.

[0033] Furthermore, a battery cooling system 9 is provided on the top of the power battery system 4; the high-voltage power distribution control system 5 is installed in an electrical cabinet, which provides protection for the high-voltage power distribution control system 5 and improves the convenience of maintenance operations.

[0034] Furthermore, the steering system 6 adopts a fully hydraulic electronically controlled steering system, adaptable to both human and autonomous driving scenarios, and meeting different operating conditions. The steering system 6 has an angle control error of 0.1° and a delay of 230ms-250ms, providing precise and rapid response, ensuring control accuracy and timeliness, and realizing chassis drive-by-wire functionality. The steering wheel rotates 4.5 turns, with a torque of 1.3-2.5 N·m, providing a comfortable driving experience. In specific implementation, the weight of the vehicle's cargo can be calibrated and monitored by monitoring changes in the air pressure of the suspension system's air springs. Built-in tire pressure monitoring allows for cargo loading and tire pressure monitoring in autonomous driving mode, improving the load-bearing capacity and lifespan of the load-bearing system.

[0035] Furthermore, the lifting system 8 adopts a dual-cylinder belly-lifting structure, resulting in a smoother lifting process and reducing the torsional torque caused by uneven material distribution during lifting. This ensures the cargo box is lifted straight and smoothly. Compared to a front-lifting system, the cargo box's X-axis dimension increases by approximately 100mm, resulting in a more optimized layout. Simultaneously, the lifting system 8 also employs a combined flow structure of a steering pump and a lifting pump, allowing the return flow from the steering system 6 to pass through the lifting pump, increasing the lifting pressure and reducing lifting time by 10%.

[0036] Furthermore, a stepped step 11 is provided on the lower left side of the offset cab 10. With the increase in vehicle size, matching the offset cab 10 with the stepped step 11 makes it safer and more convenient for the driver to get on and off the vehicle.

[0037] Furthermore, the top of the cargo box 12 is provided with a brim 13 to provide complete shielding protection for the power battery system 4, effectively reducing the risk of collisions to the power battery system 4 in complex mining areas.

[0038] Furthermore, the chassis driving system 1 adopts a central drive dual-motor drive system with a wide torque output range, adapting to various complex working conditions.

[0039] This invention matches the wheels and front and rear axle driving systems to meet the load-bearing requirements of the entire vehicle. Through adjustment and optimization of the layout dimensions, the front axle has a rated load of 40t, the middle and rear axles have a rated load of 60t, and the driving system meets the load-bearing capacity of a rated total weight of 160t, while also setting a certain overload system.

[0040] Furthermore, such as Figure 4 As shown, the braking system 3 includes a braking redundancy module 14, which is connected to the vehicle controller (VCU) 15 and the EBS system. The vehicle controller 15 is also connected to the EPB module 19 and the intelligent driving controller 16. The intelligent driving controller 16 is used to send a deceleration or stopping request to the vehicle controller 15. In response to the deceleration or stopping request, the vehicle controller 15 issues a braking command in descending order of priority of the EBS system, the braking redundancy module 14, and the EPB module 19 to achieve braking.

[0041] Specifically, the brake redundancy module 14 adopts an air brake form, and one port of the brake redundancy module 14 is connected to a first vehicle air reservoir 24, which is the original vehicle air reservoir. The braking system 3 of the present invention operates normally only if the brake chamber and the brake do not fail simultaneously.

[0042] Furthermore, the EBS system includes an EBS single-channel module 17 and an EBS dual-channel module 18. The two ports of the brake redundancy module 14 are connected to the EBS single-channel module 17 through a first dual-way check valve 21, and the two ports of the brake redundancy module 14 are also connected to the EBS dual-channel module 18 through a second dual-way check valve 22.

[0043] Furthermore, one of the air inlets of the first dual-way one-way valve 21 and the second dual-way one-way valve 22 is connected to port 2 (i.e., air outlet) of the brake redundancy module 14; the other air inlet of the first dual-way one-way valve 21 and the second dual-way one-way valve 22 is connected to the original vehicle's foot valve air pipe; the air outlet of the first dual-way one-way valve 21 is connected to port 4 of the EBS single-channel module 17, and the air outlet of the second dual-way one-way valve 22 is connected to port 4 of the EBS dual-channel module 18.

[0044] Furthermore, the braking redundancy module 14 is also connected to a power supply module 23, which is a low-voltage power supply, such as a 24V power supply. The braking redundancy module 14 communicates with the vehicle controller 15 via CAN.

[0045] Furthermore, the EPB module 19 is also connected to a second air reservoir 25; an emergency solenoid valve 20 is provided between the EPB module 19 and the vehicle controller 15; port 1 of the EPB module 19 is connected to the second air reservoir 25, port 4 of the EPB module 19 is connected to port 2 of the emergency solenoid valve 20, port 1 of the emergency solenoid valve 20 is in a blocked state, port 3 of the emergency solenoid valve 20 is open to the atmosphere, and the emergency solenoid valve 20 is powered and driven by the vehicle controller 15; the emergency solenoid valve 20 is also connected to the vehicle's emergency stop switch.

[0046] This application adds an emergency solenoid valve 20 to the EPB module 19, which is associated with the vehicle's emergency stop switch. Personnel outside the vehicle can achieve emergency braking by pressing the vehicle's emergency stop switch. It can also be set to automatically trigger after a power outage.

[0047] In this invention, multi-level braking redundancy is achieved by adding redundant braking modules and dual-way check valves to the EBS service braking system, and emergency solenoid valves and related pipelines to the EPB parking braking system. The first level of redundancy is achieved by adding the redundant braking module 14 as redundancy for the service braking system control circuit. When the EBS system controller fails, the remaining service braking system can still operate normally without reducing braking force, ensuring the vehicle braking distance is as short as possible. The second level of redundancy is achieved by using the parking circuit for overall vehicle braking redundancy. The parking circuit and service circuit are independent and generally do not activate simultaneously, resulting in a longer braking distance compared to the first level of redundancy. The third level of redundancy is achieved by using the emergency solenoid valve 20 as redundancy for the parking circuit control circuit. This is used for manual triggering and can also be set to trigger automatically after a power outage. In practical implementation, the control strategy of the multi-level braking redundancy system for the unmanned mining dump truck of this invention can be written into the control strategy of the vehicle controller 15, operating automatically according to the set logic without manual triggering, offering good convenience.

[0048] The pure electric drive, wire-controlled wide-body dump truck with a load capacity of 100 tons provided in this invention embodiment, through chassis load-bearing enhancement, power battery system upgrade, and cargo box volume increase, can increase the load capacity of the wide-body mining dump truck to 100 tons, effectively improving the vehicle's load capacity and operating efficiency to meet the transportation needs of large mines; at the same time, it adopts a more environmentally friendly pure electric power battery system. Compared with traditional fuel power sources, pure electric power sources are not only quieter and have no exhaust emissions, but also have high energy utilization, effectively reducing environmental pollution and meeting the current needs of green mine construction; it is designed and developed according to the wire-controlled vehicle design, and the initial design... Each system is designed to be compatible with an unmanned driving system, achieving a high degree of compatibility and enabling unmanned driving, thus improving economic efficiency. It can realize functions such as throttle-by-wire, steering-by-wire, braking-by-wire, and cargo box lifting-by-wire, meeting the needs of unmanned drive-by-wire vehicle transportation operations in closed mining environments. It achieves multi-level braking redundancy, ensuring that the vehicle can still decelerate and stop even if multiple parts of the vehicle's braking system fail, ensuring safety, reliability, and ease of implementation. This improves the safety performance of mining dump trucks and effectively reduces the incidence of traffic accidents. It supports the modification of existing vehicles without changing the vehicle's existing EBS service braking system and EPB parking braking system.
