Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a power assembly mounting frame and a vehicle. Background Art

[0002] The electric drive mining dump truck is the main equipment for large open-pit mine transportation. The power source adopts a generator power unit composed of an engine and a main generator. The generated electric energy is transmitted to the wheel-side traction motor through a cable and converted into mechanical energy to drive the vehicle to move. The sub-frame of the electric drive mining dump truck combines the engine, the generator and the radiator into a power assembly system. After the engine and the generator are connected, they are usually installed on the sub-frame together with the radiator in advance and then connected to the main frame. This can improve the load-bearing condition of the main frame, avoid concentrated loads, and at the same time facilitate the loading, unloading, maintenance and repair of the power assembly.

[0003] In the existing electric drive mining dump truck, the sub-frame is arranged with multiple vertically arranged shock absorbers, which are mainly used to attenuate the vibration transmitted from the engine in the vertical direction to the main frame. However, this arrangement has a small attenuation effect on the impact load, and the connecting bolts between the fixed mounting seat of the sub-frame and the main frame bear huge shear forces, resulting in insufficient connection reliability and performance in controlling the roll of the power assembly. When the vehicle is turning or accelerating / decelerating suddenly, due to the large mass of the power system carried on the sub-frame and the vibration excitation during the operation of the engine, generator, etc., the existing installation method has relatively high requirements for the structural strength of the sub-frame, shock absorbers and the performance of the connecting parts. For example, a rigid electric drive dump truck sub-frame and an electric drive dump truck disclosed in Chinese Patent Application Publication No. CN214648558U use a technical solution that can reduce the harm of roll and vibration, but it has relatively high requirements for the processing of the sub-frame and the selection of shock absorbers, increasing the material and production costs. Summary of the Utility Model

[0019] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0020] The present utility model provides a powertrain mounting frame, as Figures 1-3 shown, a powertrain mounting frame in an embodiment includes a frame 11, a mounting seat 12, and a shock-absorbing tie rod assembly 13. The frame 11 includes two longitudinal beams 111 and a plurality of cross beams. The two longitudinal beams 111 are arranged in parallel at intervals, and the two ends of the cross beam are respectively fixedly connected to the two longitudinal beams 111. There are two mounting seats 12, and the two mounting seats 12 are symmetrically distributed on the two longitudinal beams 111. One end of the shock-absorbing tie rod assembly 13 is connected to the longitudinal beam 111, and the other end is connected to the main frame (not shown in the figure). The shock-absorbing tie rod assembly 13 is used to reduce the impacts and vibrations received by the frame 11. The length direction of the shock-absorbing tie rod assembly 13 is parallel to or intersects with the length direction of the longitudinal beam 111. By setting the shock-absorbing tie rod assembly 13 in this way, a supporting force along the length direction of the frame 11 can be provided to the frame 11, and the vibration excitations during the operation of the engine, generator, etc. will not be entirely applied to the frame 11 and can be effectively alleviated through the shock-absorbing tie rod assembly 13, and the hazards of roll and vibration can be reduced.

[0021] It should be noted that the length direction of the longitudinal beam 111 in this embodiment is the length direction of the frame 11, and can also be understood as the length direction of the vehicle.

[0022] In the powertrain mounting frame and vehicle of the present utility model, by providing a shock-absorbing tie rod assembly 13 to provide a supporting force horizontally and absorb the generated impact and vibration, the vibration isolation performance can be improved, the riding comfort can be increased, the vehicle ride smoothness can be improved, the influence of the impact load on the vehicle can be reduced, the hazards of roll and vibration can be reduced, and the service life of the powertrain components on the powertrain mounting frame can be extended; moreover, the structure of the shock-absorbing tie rod assembly 13 and the selected materials are simple, and the overall material cost and production and processing cost are relatively low.

[0023] In this embodiment, there are two shock-absorbing tie rod assemblies 13, and the two shock-absorbing tie rod assemblies 13 are symmetrically distributed on both sides of the frame 11, and the two shock-absorbing tie rod assemblies 13 are respectively fixedly connected to the two longitudinal beams 111. Specifically, one end of the shock-absorbing tie rod assembly 13 is fixedly connected to the longitudinal beam 111, and the other end is fixedly connected to the main frame (not shown in the figure). Of course, the number of the shock-absorbing tie rod assemblies 13 is not limited to two, and those skilled in the art can set the number of the shock-absorbing tie rod assemblies 13 to 1, 3, 4, etc. according to the actual situation, and no unique limitation is made here.

[0024] In this embodiment, the installation position of the shock-absorbing tie rod assembly 13 is at one end close to the longitudinal beam 111. The shock-absorbing tie rod assembly 13 can also be installed at other positions, and those skilled in the art can install the installation position of the shock-absorbing tie rod assembly 13 according to the actual situation, and no unique limitation is made here.

[0025] In this embodiment, the shock-absorbing tie rod assembly 13 includes a tie rod 131, a first mounting member 132 and a second mounting member 133. The two ends of the tie rod 131 are respectively fixedly connected to the first mounting member 132 and the second mounting member 133. The first mounting member 132 is fixedly connected to the longitudinal beam 111, and the second mounting member 133 is fixedly connected to the main frame (not shown in the figure). The length direction of the tie rod 131 intersects with the length direction of the longitudinal beam 111 and forms a first included angle, and the first included angle is 5° to 45°. Those skilled in the art can set the angle of the first included angle to 5°, 10°, 15°, 20°, 22°, 25°, 30°, 35°, 40°, 45°, etc. according to the actual situation, and no unique limitation is made here.

[0026] Specifically, the two ends of the tie rod 131 are respectively fixedly connected to the first mounting member 132 and the second mounting member 133, and respectively have a first connection point and a second connection point. The distance from the first connection point to the longitudinal beam 111 is less than the distance from the second connection point to the longitudinal beam 111; as Figure 2As shown, the first connection point and the second connection point are at different horizontal heights. In this embodiment, the first connection point is located above the second connection point. It can be understood that the pull rod 131 presents an upwardly inclined state. At the same time, it extends outward at a certain angle in a direction away from the longitudinal beam 111 (the distance from the first connection point to the longitudinal beam 111 is less than the distance from the second connection point to the longitudinal beam 111). Such a setting can achieve the effect of assisting multi-directional support.

[0027] In this embodiment, the longitudinal beam 111 is a rectangular steel beam, and the shock-absorbing pull rod assembly 13 is installed on the outer sides of the two longitudinal beams 111. When the length direction of the shock-absorbing pull rod assembly 13 is parallel to the length direction of the longitudinal beam 111, the length direction of the pull rod 131 is simultaneously parallel to the outer side surface of the longitudinal beam 111. At this time, the distance from the first connection point to the longitudinal beam 111 is equal to the distance from the second connection point to the longitudinal beam 111, and the heights of the first connection point and the second connection point at the horizontal position are different, that is, the first connection point and the second connection point are not on the same horizontal line. Preferably, in this embodiment, the length direction of the shock-absorbing pull rod assembly 13 intersects the length direction of the longitudinal beam 111, that is, the length direction of the pull rod 131 intersects the outer side surface of the longitudinal beam 111. At this time, the distance from the first connection point to the longitudinal beam 111 is not equal to the distance from the second connection point to the longitudinal beam 111. Specifically, the distance from the first connection point to the longitudinal beam 111 is less than the distance from the second connection point to the longitudinal beam 111. The shock-absorbing pull rod assembly 13 provides diagonal support, improving the shock isolation performance and reducing the influence of impact loads.

[0028] In this embodiment, the first mounting member 132 is fixedly connected to the longitudinal beam 111 by bolts, and the second mounting member 133 is welded to the main frame. Of course, the first mounting member 132 can also be welded to the longitudinal beam 111, and the second mounting member 133 can also be fixedly connected to the main frame by bolts. In addition, both the first mounting member 132 and the second mounting member 133 can be fixedly connected to the longitudinal beam 111 and the main frame by bolts, or welded to the longitudinal beam 111 and the main frame.

[0029] In this embodiment, the shock-absorbing pull rod assembly 13 further includes a first shock-absorbing member 134. The first shock-absorbing member 134 is located between the first mounting member 132 and the pull rod 131. Both ends of the first shock-absorbing member 134 are connected to the first mounting member 132 and the pull rod 131 respectively. The first shock-absorbing member 134 can expand and contract along the length direction of the pull rod 131 to absorb motion shocks and vibrations.

[0030] In this embodiment, the first mounting member 132 is a bent plate. Specifically, the first mounting member 132 includes a first plate segment and a second plate segment that are sequentially connected and perpendicular to each other. The first plate segment is fixedly connected to the longitudinal beam 111, and the second plate segment is connected to the pull rod 131 through the first shock-absorbing member 134. It should be noted that the length direction of the pull rod 131 is perpendicular to the second plate segment.

[0031] In this embodiment, the mounting base 12 includes a mounting plate 121 and a second shock absorber 122. The mounting plate 121 is fixedly connected to the longitudinal beam 111, and the mounting plate 121 is connected to the main frame through the second shock absorber 122.

[0032] In this embodiment, the mounting plate 121 is located at the lower surface of the longitudinal beam 111, and a reinforcing rib 123 is welded between the side surface of the mounting plate 121 and the longitudinal beam 111. The arrangement of the reinforcing rib 123 can enhance the structural strength of the mounting base 12.

[0033] In this embodiment, the cross beam includes a first cross beam 112, a second cross beam 113 and a third cross beam 114. The mounting base 12 is mounted on the longitudinal beam 111 located between the first cross beam 112 and the second cross beam 113. At the connection of the two ends of the first cross beam 112 and the two longitudinal beams 111, a radiator mounting base 14 is provided. The radiator mounting base can be used to fixedly mount the radiator device. When installing the device, the radiator mounting base 14 is required for fixing and installation.

[0034] In this embodiment, the power assembly mounting frame further includes bracket weldments 15. There are two bracket weldments 15, and the two bracket weldments 15 are symmetrically distributed on the two longitudinal beams 111. The two bracket weldments 15 are first bolt-connected to the engine generator set (not shown in the figure), and then connected to the longitudinal beam 111 through a pin shaft. The bolt group connection is firm and reliable, and is convenient for disassembly and assembly, with strong practicability.
