Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] It should also be noted that the division of multiple embodiments in this invention is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an electric drive power module for a dump truck, including, for example, an engine assembly 11, a generator assembly 12 connected to the engine assembly 11, and a suspension structure 13. The engine assembly 11 has a first end face 112 and a second end face 114 facing each other. The engine assembly 11 includes a flywheel housing 119 connected to the first end face 112. A first flange face 111 is provided at the end of the flywheel housing 119 away from the first end face 112. The generator assembly 12 has a second flange face 121. The second flange face 121 of the generator assembly 12 is connected to the first flange face 111 of the engine assembly 11. The suspension structure 13 includes a first support 131 and a first buffer member 133. The first support 131 includes a first fixed end 131a and a second fixed end 131b. The first fixed end 131a is connected to the engine assembly 11, and the second fixed end 131b is connected to the generator assembly 12. One end of the first buffer member 133 is connected to the first support 131, and the other end of the first buffer member 133 away from the first support 131 is used to connect to the frame of a dump truck, so that the electric drive dump truck power module 10 can be fixed to the frame of the dump truck through the suspension structure 13.

[0030] Specifically, such as Figure 1 As shown, the first flange face 111 and the second flange face 121 are, for example, mated together and fixed with bolts. The fixed ends of the first support 131 are, for example, fixed to the engine assembly 11 and the generator assembly 12 respectively with bolts. The mating of the second flange face 121 with the first flange face 111 and the arrangement of the first support 131 connects the engine assembly 11 and the generator assembly 12 into a single module, resulting in a simple structure. The arrangement of the first fixed end 131a and the second fixed end 131b of the first support 131 ensures a secure connection of the electric drive dump truck power module 10.

[0031] Furthermore, such as Figure 2As shown, the first support 131 includes, for example, a first part 1311 and a second part 1312. The first part 1311 has a first end 1311a and a second end 1311b disposed opposite each other along the direction from the engine assembly 11 to the generator assembly 12. The second part 1312 is fixed to the engine assembly 11 and has a third end 1312a, a fourth end 1312b, and a connecting surface located between the third end 1312a and the fourth end 1312b. The first end 1311a is connected to the connecting surface, and the second end 1311b is fixed to the generator assembly 12. The first support 131 is fixed to the generator assembly 12 and the engine assembly 11, for example, by bolts. Its first part 1311 spans the first flange face 111 and the second flange face 121, and the first end 1311a and the second end 1311b are disposed on both sides of the two flange faces, so that the engine assembly 11 and the generator assembly 12 are stably connected, reducing the space occupied during installation. The second end 1311b, the third end 1312a, and the fourth end 1312b form a triangular structure, which stabilizes the first support 131 and the fixed structure of the engine assembly 11 and the generator assembly 12. The first support 131 may be a T-shaped structure, which provides stability and ensures a secure connection between the engine assembly 11 and the generator assembly 12.

[0032] Furthermore, such as Figure 4 As shown, the first part 1311 has a slot-shaped structure, including a slot bottom surface 13111 extending from the first end 1311a to the second end 1311b, which is fixed to the generator assembly 12. The first part 1311 also includes a first slot side surface 13112 and a second slot side surface 13113 adjacent to the slot bottom surface 13111. The first slot side surface 13112 and the second slot side surface 13113 are arranged opposite to each other, and the first slot side surface 13112 and the second slot side surface 13113 protrude from the slot bottom surface 13111 in a direction away from the generator assembly 12. The slot-shaped cross-section design provides good stress distribution and is easy to manufacture. The U-shaped support design makes the first support have better stress distribution, stronger load-bearing capacity, and is less prone to hard deformation, and also facilitates the manufacture of the first support. In addition, several mounting bases 1313 are provided on the second end 1311b, the third end 1312a and the fourth end 1312b, and are fixed, for example, welded to the side near the generator assembly 12, providing mounting holes for mounting the first support 131.

[0033] Furthermore, the first part 1311 also includes a plurality of stiffening plates 13114, which are spaced apart on the bottom surface 13111 of the groove, and each stiffening plate 13114 is connected to the first side surface 13112, the second side surface 13113, and the bottom surface 13111. The surface of the stiffening plate 13114 is perpendicular to the surface of the first side surface 13112, the second side surface 13113, and the bottom surface 13111, making the first support 131 structure more stable.

[0034] And, as Figure 1 and Figure 2 As shown, the suspension structure 13 also includes a second support 132 and a second buffer 134. The second support 132 is disposed adjacent to the second end face 114 and corresponds to the position of the first support 131. One end of the second buffer 134 is connected to the second support 132, and the other end of the second buffer 134 away from the second support 132 is used to connect to the frame of the dump truck.

[0035] Furthermore, the first buffer 133 and the second buffer 134 are, for example, rubber damping pads. For example, each buffer is fixed from the top by bolts through holes in each support, with the buffer pads facing downwards. The vibration of the engine assembly and generator assembly can be buffered by the buffers, effectively reducing the transmission of vibration to the frame and the whole vehicle. It can adapt to periodic variable loads, effectively protecting the engine, extending the service life of the equipment, and improving the driver's driving experience. Under the premise of meeting mechanical requirements, the price of rubber damping pads is relatively low, reducing costs.

[0036] Additionally, refer to Figure 2 and Figure 3 As shown, the first support 131 has a first support point 21, and the second support 132 has a second support point 22; the first buffer 133 is provided corresponding to the first support point 21; the second buffer 134 is provided corresponding to the second support point 22; the engine assembly 11 has a first center of mass 23, the generator assembly 12 has a second center of mass 24, the engine assembly 11 has a first physical weight, the generator assembly 12 has a second physical weight, the distance from the first center of mass 23 to the first end face 112 is the first lever arm, the distance from the second support point 22 to the first end face 112 is the second lever arm, the distance from the second center of mass 24 to the first end face 112 is the third lever arm, and the distance from the first support point 21 to the first end face 112 is the fourth lever arm; the first physical weight, the second physical weight, the first lever arm, the second lever arm, the third lever arm, and the fourth lever arm satisfy the following formula:

[0037]

[0038] Wherein, L1 is the first lever arm; L2 is the second lever arm; L3 is the third lever arm; L4 is the fourth lever arm; M1 is the first physical weight; and M2 is the second physical weight.

[0039] Specifically, the force analysis between the engine assembly 11, the generator assembly 12, the first support point 21, and the second support point 22 is as follows:

[0040] Let R1 be the upward vertical support force provided to the first support point 21, and R2 be the upward vertical support force provided to the second support point 22. Then, the sum of the first physical weight M1 and the second physical weight M2 is equal to the sum of R1 and R2, as shown in the following formula:

[0041] R1+R2=M1+M2

[0042] For the portion after the second support point 22, there is a torque balance, as shown in the following formula:

[0043] R1×(L2+L4)=M1×(L2-L1)+M2×(L2+L3)

[0044] For the flywheel housing 119 and generator assembly 12 after the first end face 112, there is a torque margin Mx at the first support point 21, as shown in the following formula:

[0045] Mx = R1 × L4 - M2 × L3

[0046] In each formula, L1, L2, L3, M1 and M2 are all known quantities. When the torque margin Mx is 0, the position of the first support point 21 is appropriate, that is, it is located at a distance L4 from the first end face 112 in the direction close to the generator assembly 12. This ensures that the first end face 112, that is, the rear end face of the engine cylinder block, is theoretically not subjected to the static bending moment generated by the weight of the generator. By designing the position of the rubber damping pad on the first support 131 through calculation, the stress on the engine is improved, and the cracking of the engine cylinder block is effectively avoided.

[0047] It should be noted that in this embodiment, a first mounting hole for mounting the first buffer member 133 can be correspondingly provided on the first support 131, and a second mounting hole for mounting the second buffer member 134 can be correspondingly provided on the second support 132. In some embodiments, the first support point 21 can be understood as the first mounting hole, and the second support point 22 can be understood as the second mounting hole. For example, if there is only one first buffer member 133, then a first mounting hole corresponding to the first buffer member 133 is provided on the first support 131, and the distance from the center of the first mounting hole to the first end face 112 is the same as the distance from the first support point 21 to the first end face 112. For example, if there is only one second buffer member 134, then a second mounting hole corresponding to the second buffer member 134 is provided on the second support 132, and the distance from the center of the second mounting hole to the first end face 112 is the same as the distance from the second support point 22 to the first end face 112.

[0048] In some embodiments, the first support point 21 can be understood as the center of symmetry of a plurality of first mounting holes, and the second support point 22 can be understood as the center of symmetry of a plurality of second mounting holes. When there are multiple first buffer members 133, a plurality of first mounting holes corresponding to the plurality of first buffer members 133 are formed on the first support 131, and the distance from the center of symmetry of the plurality of first mounting holes to the first end face 112 is the distance from the first support point 21 to the first end face 112. When there are multiple second buffer members 134, a plurality of second mounting holes corresponding to the plurality of second buffer members 134 are formed on the second support 132, and the distance from the center of symmetry of the plurality of second mounting holes to the first end face 112 is the distance from the second support point 22 to the first end face 112. For example, refer to... Figure 2 If two first buffers 133 are provided, then the first support point 21 is the center of symmetry of the two first buffers 133.

[0049] Alternatively, in this embodiment, a second mounting hole can be provided on the second support 132, and multiple first mounting holes can be provided on the first support 131. After calculating the length of L4 according to the above formula, an appropriate number of first buffer members 133 can be installed at suitable positions of the multiple first mounting holes. Alternatively, a first mounting hole can be provided on the first support 131, and multiple second mounting holes can be provided on the second support 132. After calculating the length of L2 according to the above formula, an appropriate number of second buffer members 134 can be installed at suitable positions of the multiple second mounting holes.

[0050] Furthermore, there are two first supports 131, each positioned on opposite sides of the generator assembly 12; and two second supports 132, each positioned on opposite sides of the engine assembly 11. Even further, for example, the distances from the two first supports 131 to the first end face 112 are equal. This symmetrical arrangement of supports simplifies stress analysis calculations and ensures symmetrical stress distribution on the power module after installation, preventing tilting.

[0051] In addition, such as Figure 5 As shown, the second support 132 includes a mounting plate 1321, a damping plate 1322, a vertical plate 1323, and mounting stiffeners 1324. The mounting plate 1321 can be fixed to the engine assembly 11, for example, by bolts. The damping plate 1322 is, for example, an inverted L-shaped plate. Several vertical plates 1324 are arranged parallel to each other, for example, welded to one side of the mounting plate 1321 where the damping plate 1322 is located, for connecting the damping plate 1322 and the mounting plate 1321. The surface of the vertical plate 1323 is perpendicular to the mounting plate 1321. The mounting stiffeners 1324 connect the vertical plates 1323, the mounting plate 1321, and the damping plate 1322, and are arranged on the front and rear sides of the vertical plates 1323, making the structure of the second support 132 more stable.

[0052] An embodiment of the present invention provides an electric drive mining dump truck, including a frame, and a power module as in the previous embodiment, which is fixed to the frame by a suspension structure 13. The suspension structure 13 has few suspension points, is simple to install, and is easy to maintain.

[0053] The above embodiments of the present invention can achieve one or more of the following beneficial effects: By connecting the engine assembly and the generator assembly with flange faces and by designing a first support to connect the engine assembly and the generator assembly, the embodiments of the present invention make the connection between the engine assembly and the generator assembly firm, simple to install, and convenient to maintain. By setting a second support and a first support on the engine assembly and the generator assembly and designing and installing a buffer component, the power module is mounted on the frame, reducing the number of support points and reducing the transmission of engine vibration to the frame and the entire vehicle, while also facilitating stress analysis and subsequent equipment maintenance. By designing the positions of the support points and buffer components through calculation schemes, the rear end of the engine block of the engine assembly is theoretically not subjected to the static bending moment generated by the mass of the generator assembly, improving the stress on the engine and preventing engine block cracking.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
