DETAILED DESCRIPTION

[0022] In order to enable a more complete understanding of the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein, therefore, the protection scope of the present disclosure is not limited by the specific embodiments disclosed below.

[0024] The following description will be made with reference to the accompanying drawings. Figures 1 to 4A multi-power hybrid transmission system 100 and an electric wheel device are described according to some embodiments of the present disclosure. The electric wheel device includes the multi-power hybrid transmission system 100, which provides power for the electric wheel device. The electric wheel device can be an electric wheel mine dump truck or other equipment that meets the requirements. For example, the electric wheel device provided by the embodiments of the present disclosure can be a large-tonnage electric wheel mine dump truck.

[0025] In large mines, due to the need for production capacity, large-tonnage electric wheel devices are usually used, which have the characteristics of large load, large self-weight, large volume, and large power. The power system generally adopts a single generator module. Since the engine, generator, radiator, and other parts of the single generator module have large power, the equipment is large, there are fewer manufacturers and models that can provide corresponding mature models at home and abroad, and there are problems such as high prices of parts, long delivery cycle, high cost of maintenance and replacement, long delivery cycle of spare parts, and the risk of technical monopoly.

[0026] Therefore, as shown in Figure 3 and Figure 4 the embodiments of the first aspect of the present disclosure provide a multi-power hybrid transmission system 100, which includes a double-generator module 110, the double-generator module 110 includes two single-generator modules 120 with the same structure; an electric wheel module 130; a variable current module 140, each single-generator module 120 is electrically connected with the variable current module 140, and the variable current module 140 is electrically connected with the electric wheel module 130.

[0027] In the present disclosure, the two single-generator modules 120 with the same structure are electrically connected with the variable current module 140 to replace one large single-generator module in the related art to provide electric energy for the electric wheel module 130, so as to ensure that the total output electric power of the double-generator module 110 is sufficient to ensure that the electric wheel device can operate normally. Since the two single-generator modules 120 with the same structure replace one large single-generator module in the related art, compared with the large single-generator module in the related art, each single-generator module 120 in the present disclosure has smaller volume and size, lower cost, and smaller power, and the internal component structure size is smaller, thereby avoiding the technical monopoly of the large-power single-generator module at home and abroad, so that more manufacturers can provide single-generator modules 120 and related spare parts that meet the embodiments of the present disclosure, expand the suppliers of single-generator modules 120 and their spare parts, thereby shortening the delivery cycle, and the two single-generator modules 120 with smaller volume can be installed and repaired respectively compared with the large single-generator module in the related art, thereby facilitating installation and repair, saving maintenance and replacement costs, and being suitable for popularization and application.

[0028] Further, the two single-generator modules 120 constituting the double-generator module 110 are of the same structure, so that the spare parts of the two single-generator modules 120 can be universal, which is conducive to further saving the maintenance and spare part costs of the multi-power hybrid transmission system 100.

[0029] Further, the current conversion module 140 is used to combine the electric energy of the two single-generator modules 120 and convert the unstable alternating current into stable current for driving or energy storage recovery of the motor wheel module 130.

[0030] In some possible implementation embodiments provided by the present disclosure, as shown in Figure 3 The multi-power hybrid transmission system 100 further includes an energy storage module 150 electrically connected with the current conversion module 140 and used for storing and / or supplying energy. Specifically, the energy storage module 150 can include a power battery electrically connected with the current conversion module 140, so that the power battery can be used for energy recovery and storage when the motor wheel device is in a low-power consumption state, such as a slow-down, braking or deceleration stage on a downhill slope. When a high-power demand is integrated, such as a stage on an uphill slope, the power battery can be used as a functional component to supplement power to the motor wheel module 130 to assist the motor wheel module 130 to act, so as to achieve the purposes of reducing fuel consumption and improving power performance.

[0031] Further, the energy storage module 150 is a replaceable component. When the total power provided by the double-generator module 110 is sufficient, i.e., the power provided by the two single-generator modules 120 together meets the driving demand of the motor wheel device in various working conditions, the energy storage module 150 can be omitted to simplify the structure of the multi-power hybrid transmission system 100, reduce the volume of the multi-power hybrid transmission system 100, and reduce the cost of the multi-power hybrid transmission system 100. When the total power provided by the double-generator module 110 cannot meet the driving demand of the motor wheel device in various working conditions, the energy storage module 150 can be added to ensure that the motor wheel device can normally operate and is conducive to saving energy and reducing fuel consumption.

[0032] In some possible implementation embodiments provided by the present disclosure, as shown in Figure 3 The multi-power hybrid transmission system 100 further includes a resistance grid module 160 electrically connected with the current conversion module 140 and used for consuming excess electric energy. The resistance grid module 160 is used to consume the electric energy exceeding the recovery capability range of the energy storage module 150 when the motor wheel device is slowly running on a downhill slope or braking.

[0033] In some possible implementation embodiments provided by the present disclosure, as shown in Figure 3As shown, the dual generator module 110 and the electric wheel module 130 are distributed on both sides of the first centerline 211 along the first direction, where the first centerline 211 is the centerline of the frame assembly 210 parallel to the first direction; wherein, the first direction is as follows Figure 2 The front-to-back direction shown is like the front-to-back direction of an electric wheel device; the second direction is like... Figure 2 The left and right directions are shown, such as the left and right directions of an electric wheel device.

[0034] In some possible implementations provided in this disclosure, such as Figure 4 As shown, the single generator module 120 includes a radiator 121, an internal combustion engine 122, a generator 123, and a mounting bracket 124. The radiator 121, the internal combustion engine 122, and the generator 123 are connected in series and are mounted on the mounting bracket 124 in sequence along a first direction, so that the single generator module 120 can be transported and disassembled independently as a whole, thus facilitating transportation and installation.

[0035] Furthermore, since this embodiment utilizes two single generator modules 120 instead of a larger single generator module, the power of each single generator module 120 is smaller. The dimensions of the radiator 121, internal combustion engine 122, and generator 123 in each single generator module 120 are smaller than the corresponding components in larger single generator modules in related technologies. Therefore, by integrating the radiator 121, internal combustion engine 122, and generator 123 of the single generator module 120 together using the mounting bracket 124, the module is smaller and lighter, allowing it to be independently towed and hoisted as a whole, thus facilitating transportation and installation. For example, the mounting bracket 124 can be used to quickly install the single generator module 120 onto the vehicle frame assembly, or to remove it from the vehicle frame assembly 200.

[0036] Furthermore, from the radiator 121 to the generator 123, the width of the single generator module 120 decreases. That is, the single generator module 120 has a trapezoidal structure that is wider at one end and narrower at the other. This arrangement allows the shape of the single generator module 120 to match the installation space of the frame assembly 200 as much as possible, so that the dual generator module 110 can be fully accommodated in the installation space, reducing the size of the electric wheel equipment.

[0037] Furthermore, the multi-power hybrid transmission system 100 includes a control module or a converter module 140 built into the control module. In this way, when the entire electric wheel equipment is under low power demand, the control module adopts a certain control strategy to make the internal combustion engine 122 operate at the optimal fuel economy speed, thereby significantly reducing fuel consumption.

[0038] The multi-power hybrid transmission system 100 provided by the embodiments of the present disclosure comprises a power part, a driving part and an energy recovery part. The power part comprises a double-generator module 110, which utilizes two single-generator modules 120 with the same structure to form a double-power system and is electrically driven. Each single-generator module 120 is an independent module, which comprises an internal combustion engine 122, a generator 123, a cooling system, an air intake system, an exhaust system and the like. The driving system comprises a variable current module 140, a resistance barrier module 160, an electric wheel module 130 and the like. The variable current module 140 comprises a variable current device, which is used to combine the electric energy of the two single-generator modules 120, convert the unstable alternating current into stable current and drive or store the energy of the electric wheel module 130. The energy recovery part comprises an energy storage module 150, which is a power battery. The power battery is used to store the recovered energy of the device when it is descending, braking and decelerating, and to assist the electric wheel driving when the device is ascending. The resistance barrier module 160 is used to consume the electric energy exceeding the recovery capacity of the power battery when the device is descending and braking slowly.

[0039] As shown in the second aspect of the embodiments of the present disclosure, Figure 1 and Figure 2 An electric wheel device is provided, which comprises a frame assembly 200 and the multi-power hybrid transmission system 100 of any one of the first aspect. The multi-power hybrid transmission system 100 is directly or indirectly connected with the frame assembly 200. Since the electric wheel device comprises the multi-power hybrid transmission system 100 of any one of the first aspect, the electric wheel device has all the beneficial technical effects of the multi-power hybrid transmission system 100, which will not be repeated here.

[0040] Further, each single-generator module 120 is detachably connected with the frame assembly 200, that is, each single-generator module 120 can be hoisted, transported and assembled as a whole. That is, each single-generator module 120 can be separately installed on or detached from the frame assembly 200, which is convenient for assembly and maintenance.

[0041] In some possible implemented embodiments provided by the present disclosure, as Figure 2As shown, the frame assembly 200 includes two frame longitudinal beams 210 arranged opposite to each other along the second direction, for example, the two frame longitudinal beams 210 are arranged along the left-right direction of the electric wheel device, and the frame longitudinal beams 210 include front ends and rear ends arranged opposite to each other along the first direction, for example, the front ends and the rear ends are arranged along the front-rear direction of the electric wheel device.

Such arrangement is that the electric wheel module 130 is just located at the rear part of the frame assembly 200, facilitating the connection with the rear axle of the electric wheel device, and enabling the multi-power hybrid transmission system 100 to be more reasonably arranged on the frame assembly 200.

[0042] As shown, the frame assembly 200 includes two frame longitudinal beams 210 arranged opposite to each other along the second direction, for example, the two frame longitudinal beams 210 are arranged along the left-right direction of the electric wheel device, and the frame longitudinal beams 210 include front ends and rear ends arranged opposite to each other along the first direction, for example, the front ends and the rear ends are arranged along the front-rear direction of the electric wheel device.

[0043] In the above embodiment, as shown, Figure 2 As shown, the frame assembly 200 includes a first center line 211, the first center line 211 is parallel to the first direction, that is, the first center line 211 is located between the two frame longitudinal beams 210 and extends along the front-rear direction of the device, and the distance from any point on the first center line 211 to the two frame longitudinal beams 210 is equal. The two single-generator modules 120 are symmetrically distributed along the first center line 211, which enables the two single-generator modules 120 to be reasonably and uniformly distributed in the installation space surrounded by the two longitudinal beams, thereby facilitating the improvement of the stability of the device gravity center.

The multi-power hybrid transmission system 100 is arranged inside between the two frame longitudinal beams 210, the double-generator module 110 is arranged close to the front ends of the frame longitudinal beams 210, and the electric wheel module 130 is arranged close to the rear ends of the frame longitudinal beams 210. Such arrangement is that the electric wheel module 130 is just located at the rear part of the frame assembly 200, facilitating the connection with the rear axle of the electric wheel device, and enabling the multi-power hybrid transmission system 100 to be more reasonably arranged on the frame assembly 200. As shown, the frame assembly 200 includes two frame longitudinal beams 210 arranged opposite to each other along the second direction, for example, the two frame longitudinal beams 210 are arranged along the left-right direction of the electric wheel device, and the frame longitudinal beams 210 include front ends and rear ends arranged opposite to each other along the first direction, for example, the front ends and the rear ends are arranged along the front-rear direction of the electric wheel device.

[0045] In the above embodiments, as shown in Figure 2 Each single-generator module 120 includes a second center line 125 parallel to the direction of the heat sink 121 to the generator 123 in the single-generator module 120, and the included angle between the second center line 125 and the first center line 211 is greater than 0° and less than or equal to 20°, that is Figure 2 α in the above satisfies 0° < α ≤ 20°, so as to ensure that the double-generator module 110 as a whole can be reasonably installed in the accommodating space surrounded by the two longitudinal beams, so that the structure of the entire device is compact, and the width of the entire vehicle can be ensured.

[0046] Further, as shown in Figure 1 and Figure 2 The electric wheel device provided by the embodiments of the present disclosure further includes a cab 300 and a truck box 500, which are arranged on the frame assembly 200 in the front-rear direction, and the truck box 500 is used to accommodate materials.

[0047] The electric wheel device provided by the present disclosure, as shown in Figures 1 to 4 By changing the technical scheme of the single-generator module adopted by the electric wheel device in the related art, two single-generator modules 120 independent of each other are adopted to form a double-generator module 110, so as to ensure that the total power generation of the double-generator module 110 is sufficient. This technical scheme can avoid the technical monopoly of foreign high-power internal combustion engines 122, and can greatly reduce the procurement cost of the main machine. At the same time, by controlling the module adjustment control strategy, the fuel economy can be improved, such as when the device has low power demand, a certain control strategy is adopted to make the internal combustion engine 122 work at the best fuel economy speed, thereby greatly reducing fuel consumption.
