Description

Technical Field

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

[0002] At present, the power transmission route of the frame assembly is transmitted from the engine to the transmission and transfer case, and the transfer case then divides the front and rear drive shafts to transmit them to the front and rear axle main reducers, and finally the front and rear axle drive shafts drive the wheels. The fuel tank and exhaust system are arranged on the inner side of the longitudinal beam in the middle section of the frame. The frame assembly provides installation points and collision protection for them. The frame assembly can also provide installation locations for the suspension system, steering system, traction system and body frame system, so that the frame assembly can withstand the forces and torques transmitted by multiple systems.

[0003] In order to ensure the performance and normal operation of the vehicle, the frame assembly needs to ensure sufficient strength and be able to withstand stress under various working conditions. It also needs to ensure sufficient static and dynamic stiffness to prevent individual components from being easily deformed during operation. The frame assembly also provides collision protection for the vehicle. During a collision, the frame assembly absorbs collision energy, thereby enabling the frame assembly to protect other components.

[0004] In the related technology, when the power system of the vehicle is a decoupled four-wheel drive, a smaller displacement engine and a shorter transmission are used, and the layout of the transfer case and the rear axle drive shaft are cancelled. This will cause the related brackets and beams of the power installation in the frame assembly to be unable to meet the power system requirements, and the frame assembly will also be unable to meet the requirements of installing the power battery, and will also be unable to meet the layout of the drive structure, and thus will be unable to match a suitable motor drive structure.

The multiple frame cross beams 12 are arranged at intervals in the longitudinal direction, so that the multiple frame cross beams 12 and the frame longitudinal beams 11 can form a frame structure, thereby improving the overall structural strength of the frame assembly 100 and facilitating the installation of other components on the frame assembly 100.

[0038] In addition, a plurality of frame cross beams 12 separate a first drive structure installation area 13, a power battery installation area 14, a fuel tank installation area 15 and a second drive structure installation area 16 in the longitudinal direction of the frame 10. This arrangement allows the first drive structure to be installed in the first drive structure installation area 13, the power battery to be installed in the power battery installation area 14, the fuel tank to be installed in the fuel tank installation area 15, and the second drive structure to be installed in the second drive structure installation area 16. This allows the first drive structure, the power battery, the fuel tank and the second drive structure to be spaced apart in the longitudinal direction of the frame assembly 100, and allows the first drive structure, the power battery, the fuel tank and the second drive structure to not interfere with each other, thereby facilitating the arrangement of various structures in the frame assembly 100, and also improving the platformization of the frame assembly 100, and reducing R&D costs.

[0040] Therefore, by separating the first drive structure installation area 13, the power battery installation area 14, the fuel tank installation area 15 and the second drive structure installation area 16 in the longitudinal direction of the frame 10, the first drive structure, the power battery, the fuel tank and the second drive can be installed on the frame assembly 100, and the second drive structure installation area 16 is provided with a subframe 30, and the subframe 30 is provided with a suspension mounting bracket of the second drive structure, so that the subframe 30 and the frame 10 can be connected, and the suspension can also be installed on the frame assembly 100, thereby satisfying the layout of the power system and the motor drive, and improving the overall performance of the vehicle.

[0041] Among them, Figure 1-Figure 3 As shown, the multiple frame beams 12 include: a first beam 121, a second beam 122, a third beam 123, a fourth beam 124, a fifth beam 125, a sixth beam 126 and a seventh beam 127 arranged in sequence from front to back; wherein, a first drive structure installation area 13 is formed between the second beam 122 and the fourth beam 124; a power battery installation area 14 is formed between the fourth beam 124 and the fifth beam 125; a fuel tank installation area 15 is formed between the fifth beam 125 and the sixth beam 126; and a second drive structure installation area 16 is formed between the sixth beam 126 and the seventh beam 127.

[0042] It can be understood that the first cross beam 121, the second cross beam 122, the third cross beam 123, the fourth cross beam 124, the fifth cross beam 125, the sixth cross beam 126 and the seventh cross beam 127 constitute the frame cross beam 12, and the first cross beam 121, the second cross beam 122, the third cross beam 123, the fourth cross beam 124, the fifth cross beam 125, the sixth cross beam 126 and the seventh cross beam 127 are arranged in sequence along the front-to-back direction of the frame 10, so that a mounting area can be formed between the plurality of frame cross beams 12, and a first drive structure mounting area 13 can be formed between the second cross beam 122 and the fourth cross beam 124. In this way, the first drive structure can be mounted in the first drive structure mounting area 13, and the fourth cross beam 12 A power battery installation area 14 is formed between the fifth crossbeam 125 and the fifth crossbeam 125, and the power battery can be installed in the power battery installation area 14. A fuel tank installation area 15 is formed between the fifth crossbeam 125 and the sixth crossbeam 126, and the fuel tank can be installed in the fuel tank installation area 15. A second drive structure installation area 16 is formed between the sixth crossbeam 126 and the seventh crossbeam 127, and the second drive structure can be installed in the second drive structure installation area 16, so that the first drive structure, the power battery, the fuel tank and the second drive structure do not interfere with each other, thereby facilitating the arrangement of various structures in the frame assembly 100, improving the platformization of the frame assembly 100, and reducing R&D costs.

[0043] In addition, if Figure 1-Figure 3As shown, the first drive structure installation area 13 is used to install the first drive structure, the first drive structure includes an engine and a transmission, the engine and the transmission are transmission-connected, the first drive structure installation area 13 includes an engine installation area and a transmission installation area; the engine installation area is formed between the second cross beam 122 and the third cross beam 123; the transmission installation area is formed between the third cross beam 123 and the fourth cross beam 124.

[0044] That is to say, the first drive installation area can limit the first drive structure, so as to facilitate the installation of the first drive structure in the frame assembly 100. The engine and the transmission constitute the main body of the first drive structure. The engine and the transmission are connected in transmission, so that the power of the engine can be output to the transmission, and the transmission controls the power, and finally transmits the power to the wheels of the locomotive, so as to realize the operation of the vehicle. The engine installation area and the transmission installation area constitute the main body of the first drive structure installation area 13. The engine installation area is formed between the second cross beam 122 and the third cross beam 123. Such an arrangement allows the engine to be installed in the engine installation area. The transmission installation area is formed between the third cross beam 123 and the fourth cross beam 124. Such an arrangement allows the transmission to be installed in the transmission installation area, so that the engine and the transmission can be arranged with a front-to-back interval, so as to facilitate the power output of the engine to the transmission.

[0045] In addition, if Figure 1-Figure 3 As shown, the vehicle frame 10 further includes: an engine suspension mounting plate 17 and a front shock absorber support 18. The engine suspension mounting plate 17 is connected to a portion of the frame longitudinal beam 11 located between the second cross beam 122 and the third cross beam 123. The front shock absorber support 18 is connected to a portion of the frame longitudinal beam 11 located between the second cross beam 122 and the third cross beam 123.

[0046] It can be understood that an engine suspension mounting plate 17 is set on the frame longitudinal beam 11 located on the left side, and an engine suspension mounting plate 17 is set on the frame longitudinal beam 11 located on the right side, so that the two engine suspension mounting plates 17 can be arranged opposite to each other on the left and right, and the engine suspension mounting plate 17 is located between the second cross beam 122 and the third cross beam 123. This arrangement is convenient for the engine suspension mounting plate 17 to limit the engine, so that the engine can be installed in the engine installation area, and the engine suspension mounting plate 17 can also improve the connection strength between the engine and the frame 10, thereby ensuring the performance of the engine. The front shock absorber support 18 is located between the second cross beam 122 and the third cross beam 123. The front shock absorber support 18 can limit the shock absorber, so that the shock absorber can be set on the frame 10, and the front shock absorber support 18 is connected to the engine suspension mounting plate 17. This arrangement can make the front shock absorber and the engine adjacent to each other, so that the front shock absorber can reduce the vibration of the engine, thereby ensuring the performance of the engine.

[0047] Among them, Figure 1-Figure 3 As shown, the engine suspension mounting plate 17 includes: an engine suspension lower mounting plate 171 and an engine suspension upper mounting plate 172. The engine suspension lower mounting plate 171 is connected to the frame longitudinal beam 11, and the engine suspension upper mounting plate 172 is connected to the upper part of the engine suspension lower mounting plate 171. The engine suspension upper mounting plate 172 is connected to the front shock absorber support 18, and the engine suspension upper mounting plate 172 is installed with a threaded mounting part.

[0048] That is to say, the engine suspension lower mounting plate 171 and the engine suspension upper mounting plate 172 constitute the main structure of the engine suspension mounting plate 17, and the engine suspension lower mounting plate 171 is connected to one side of the frame longitudinal beam 11, so that the engine suspension mounting plate 17 can be set on the frame longitudinal beam 11, and the engine suspension upper mounting plate 172 and the engine suspension lower mounting plate 171 are arranged relative to each other in the vertical direction, so that a cavity can be formed in the engine suspension upper mounting plate 172 and the engine suspension lower mounting plate 171, thereby improving the engine suspension. The structural strength of the mounting plate 17, the engine suspension upper mounting plate 172 is connected to the front shock absorber support 18, so that the front shock absorber support 18 and the engine suspension mounting plate 17 can be connected. This arrangement allows the front shock absorber and the engine to be arranged adjacent to each other, so that the front shock absorber can reduce the vibration of the engine, thereby ensuring the performance of the engine. The engine suspension upper mounting plate 172 is installed with a threaded mounting part, so that the engine can be easily installed on the engine suspension mounting plate 17 through the threaded mounting part, and then the engine can be installed on the frame 10.

[0049] In addition, if Figure 1-Figure 3 As shown, the frame assembly 100 further includes: a transmission suspension mounting plate 19, which is connected to the middle portion of the front side surface of the fourth cross beam 124 and protrudes forward.

[0050] It can be understood that the transmission suspension mounting plate 19 is located on the front side of the fourth cross beam 124, and the transmission suspension mounting plate 19 is protruding relative to the front side of the fourth cross beam 124, so that the transmission suspension mounting plate 19 can limit the transmission, thereby facilitating the installation of the transmission on the frame 10, and the transmission suspension mounting plate 19 is located in the middle of the fourth cross beam 124. This arrangement can improve the bearing capacity of the transmission suspension mounting plate 19, thereby improving the connection relationship between the transmission and the frame 10, and thereby ensuring the performance of the transmission.

[0051] Among them, Figure 1-Figure 3As shown, the transmission suspension mounting plate 19 includes: a transmission suspension lower mounting plate 191 and a transmission suspension upper mounting plate 192, the transmission suspension lower mounting plate 191 is connected to the side and bottom of the fourth cross beam 124, the transmission suspension upper mounting plate 192 is connected to the top of the transmission suspension lower mounting plate 191, and the transmission suspension upper mounting plate 192 is connected to the side and top of the fourth cross beam 124.

[0052] That is to say, the transmission suspension lower mounting plate 191 and the transmission suspension upper mounting plate 192 constitute the main structure of the transmission suspension mounting plate 19, the transmission lower mounting plate is connected to the side and bottom of the fourth cross beam 124, and the transmission suspension upper mounting plate 192 is connected to the side and top of the fourth cross beam 124. This arrangement can connect the transmission suspension mounting plate 19 to three surfaces of the fourth cross beam 124, so that the transmission suspension mounting plate 19 can be set on the fourth cross beam 124, and the transmission suspension upper mounting plate 192 and the transmission suspension lower mounting plate 191 are arranged relative to each other in the up and down directions, so that a cavity can be formed in the transmission suspension upper mounting plate 192 and the transmission suspension lower mounting plate 191, thereby improving the structural strength of the transmission suspension mounting plate 19.

[0053] In addition, if Figure 1-Figure 3 As shown, the vehicle frame assembly 100 further includes: a transmission limiting bracket 20, which is connected to the top surface of the fourth cross beam 124 and protrudes upward. It can be understood that the transmission limiting bracket 20 is located on the top surface of the fourth cross beam 124, the transmission limiting bracket 20 protrudes upward relative to the fourth cross beam 124, and the transmission limiting bracket 20 and the transmission suspension mounting plate 19 are arranged adjacent to each other, so that the transmission is conveniently installed on the vehicle frame 10 through the transmission limiting bracket 20 and the transmission suspension mounting plate 19, thereby saving the assembly time of the transmission and improving the assembly accuracy of the transmission.

[0054] In addition, if Figure 1-Figure 3 As shown, the frame 10 also includes: a cross beam connecting plate 21, the cross beam connecting plate 21 is connected to the frame longitudinal beam 11, the cross beam connecting plate 21 is formed with a mounting groove, the end of the fourth cross beam 124 extends into the mounting groove, and the cross beam connecting plate 21 is detachably connected to the end of the fourth cross beam 124 through a fastener.

[0055] That is to say, the left cross beam connecting plate 21 is connected to the left frame longitudinal beam 11, and the right cross beam connecting plate 21 is connected to the right frame longitudinal beam 11. The two cross beam connecting plates 21 are arranged opposite to each other, and a mounting groove is arranged on the side of the cross beam connecting plate 21 facing the center of the frame 10. Both ends of the fourth cross beam 124 extend into the mounting groove, so that the mounting groove can limit the fourth cross beam 124, thereby facilitating the connection of the fourth cross beam 124 between the frame longitudinal beams 11. The fasteners are passed through the mounting grooves, that is, the fasteners can pass through the cross beam connecting plate 21 and the fourth cross beam 124, thereby facilitating the installation and disassembly between the cross beam connecting plate 21 and the fourth cross beam 124.

[0056] In particular, if Figure 1-Figure 3 As shown, the height of the end of the fourth cross beam 124 is greater than the height of the middle of the fourth cross beam 124. This arrangement can make the two ends of the fourth cross beam 124 bear a greater degree of stress, thereby making the connection between the fourth cross beam 124 and the cross beam connecting plate 21 more secure, thereby improving the overall structural strength of the frame 10.

[0057] Alternatively, if Figure 1-Figure 3 As shown, a plurality of fasteners are arranged between the end of the fourth beam 124 and the beam mounting plate, and the plurality of fasteners are arranged at intervals in the height direction and the length direction of the fourth beam 124. It can be understood that a plurality of fasteners are arranged at the connection between the end of the fourth beam 124 and the beam mounting plate, and the plurality of fasteners are arranged at intervals in the height and length direction of the fourth beam 124, so that the plurality of fasteners can be arranged obliquely, and such an arrangement can increase the installation spacing and height difference between the plurality of fasteners, and thus can improve the dynamic stiffness performance between the fourth beam 124 and the beam connecting plate 21.

[0058] Among them, Figure 1-Figure 4 As shown, the cross-beam connecting plate 21 includes: a cross-beam connecting front plate 211, a cross-beam connecting rear plate 212 and a reinforcing plate 213. The cross-beam connecting rear plate 212 is connected to the rear side of the cross-beam connecting front plate 211. The reinforcing plate 213 is arranged in a cavity between the cross-beam connecting front plate 211 and the cross-beam connecting rear plate 212 and is respectively connected to the cross-beam connecting front plate 211 and the cross-beam connecting rear plate 212.

[0059] That is to say, the cross-beam connecting front plate 211, the cross-beam connecting rear plate 212 and the reinforcing plate 213 constitute the main structure of the cross-beam connecting plate 21. The cross-beam connecting front plate 211 and the cross-beam connecting rear plate 212 are relatively arranged in the front-to-back direction, so that a cavity can be formed between the cross-beam connecting front plate 211 and the cross-beam connecting rear plate 212, thereby improving the structural strength and rigidity of the cross-beam connecting plate 21. The reinforcing plate 213 is connected between the cross-beam connecting front plate 211 and the cross-beam connecting rear plate 212, thereby improving the structural strength and rigidity of the cross-beam connecting plate 21, and also enabling the cross-beam connecting plate 21 to transfer the force of the transmission suspension mounting plate 19 to the frame longitudinal beam 11, thereby ensuring the safety performance of the frame 10.

[0060] In addition, if Figure 1-Figure 3 As shown, the frame 10 also includes: a first power battery mounting bracket 22 and a second power battery mounting bracket 23, the first power battery mounting bracket 22 is connected to the fourth cross beam 124, and the second power battery mounting bracket 23 is connected to the portion of the frame longitudinal beam 11 located between the fourth cross beam 124 and the fifth cross beam 125.

The middle part of the sub-frame longitudinal beam 31 is connected to one end of the sub-frame mounting plate 34, and the sub-frame mounting plate 34 extends away from the center direction of the sub-frame longitudinal beam 31, and the other end of the sub-frame mounting plate 34 is provided with a middle mounting portion.
