Description

Technical Field

[0001] The present application relates to the technical field of power suspension working condition detection, and in particular to a power suspension load acquisition device and tooling. Background Art

[0002] A vehicle's operating conditions refer to its operating state during driving. They are generally categorized into typical conditions, extreme conditions, and misuse conditions. Misuse conditions include abnormal operations such as falling into a pothole, braking over a speed bump, and curb impacts, or even individual events caused by driver error. These conditions subject the vehicle to extreme forces and can easily cause serious damage. Therefore, when conducting vehicle safety inspections, it's necessary to simulate and analyze the strength of each component under misuse conditions to prevent structural damage.

[0003] Currently, there are no clear standards within the industry for simulation analysis of the strength of power mounts under misuse conditions. Existing technology typically attaches acceleration sensors to the power mount during vehicle misuse testing to collect the maximum acceleration of the power mount under various misuse conditions. However, this acceleration value cannot be effectively converted into the load on the power mount and is not useful for simulation analysis of the strength of power mounts under misuse conditions. Therefore, it is necessary to design a power mount load acquisition device for vehicle misuse testing that can directly collect the load on the power mount under various misuse conditions for use in simulation analysis of the strength of power mounts under misuse conditions.

[0033] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0034] like Figures 1 to 3 As shown, this embodiment provides a dynamic suspension load collection device, including a first suspension bracket 1, a second suspension bracket 2 and a three-force sensor 3. The first suspension bracket 1 is used to be detachably fixedly connected to the frame assembly 100 and has a first mounting surface 111 arranged perpendicular to the vehicle height direction; the second suspension bracket 2 is used to be detachably fixedly connected to the power assembly 200 and has a second mounting surface 211 arranged perpendicular to the vehicle height direction, and the second mounting surface 211 is opposite to and spaced from the first mounting surface 111; the three-force sensor 3 has two force-bearing ends (a first force-bearing end 31 and a second force-bearing end 32) arranged opposite to each other along the vehicle height direction. The three-force sensor 3 is arranged between the first suspension bracket 1 and the second suspension bracket 2, and the two force-bearing ends 31 / 32 are respectively fixed to the first mounting surface 111 and the second mounting surface 211; wherein the first mounting surface 111 and / or the second mounting surface 211 is provided with a mounting groove 112 concave in the surface of the mounting surface, and the mounting groove 112 is adapted to the shape of the force-bearing ends 31 / 32. In this way, the mounting groove 112 concavely arranged on the mounting surface can be used to accommodate the force-bearing ends 31 / 32 of the three-force sensor 3, which can reduce the space occupied by the three-force sensor 3 without changing the original suspension mounting base point; at the same time, by arranging the first mounting surface 111 and the second mounting surface 211 opposite to each other and spaced apart in the vehicle height square, the two force-bearing ends 31 / 32 of the three-force sensor 3 can be maintained in the vehicle height direction, reducing the impact on the three-force sensor 3 under misuse conditions, and thus effectively collecting the load on the power suspension under misuse conditions, and can be directly applied to the suspension strength analysis, providing data support for the subsequent forward design of the power suspension assembly under misuse conditions.

[0035] It can be understood that the above-mentioned first mounting surface 111 and the second mounting surface 211 are always arranged at a relative interval in the vehicle height direction, that is, when the above-mentioned first mounting surface 111 and the second mounting surface 211 are both provided with mounting grooves 112, the depth of the mounting groove 112 of any one mounting surface or the total depth of the mounting grooves 112 on the two mounting surfaces is less than the height of the three-force sensor 3, that is, the distance between the two force-bearing ends 31 / 32, so that when the three-force sensor 3 is accommodated in the mounting groove 112, the two force-bearing ends 31 / 32 at both ends can be supported between the first mounting surface 111 and the second mounting surface 211, and the first mounting surface 111 and the second mounting surface 211 are arranged at a relative interval in the vehicle height direction, thereby accurately and effectively obtaining the load received by the dynamic suspension under misuse conditions.

[0036] In some embodiments, as Figures 1 to 3 As shown, at least one force-bearing end, such as force-bearing end 31, is provided with a non-circular boss 311 protruding outward from the profile. The mounting groove 112 is shaped to match the boss 311. When the three-force sensor 3 is disposed between the first suspension bracket 1 and the second suspension bracket 2, the boss 311 is inserted into the mounting groove 112. The cooperation between the boss 311 and the mounting groove 112 facilitates the positioning of the three-force sensor 3 on the mounting surface during installation. Furthermore, the mutually compatible non-circular shapes of the boss 311 and the mounting groove 112 prevent the boss 311 from rotating within the mounting groove 112, thereby affecting the accuracy of load data collection. It will be understood that in this embodiment, the boss 311 serves as part of the first force-bearing end 31. When the boss 311 is inserted into the mounting groove 112, the boss 311 and the end surface of the three-force sensor 3 surrounding the boss 311 are in contact with the mounting surface having the mounting groove 112 and receive force, thereby obtaining the load applied to the corresponding suspension bracket.

[0037] Further, such as Figure 1 As shown, the depth of the mounting groove 112 can also be set to be smaller than the setting height of the boss 311. In this way, only the boss 311 can be used as the force-bearing end 31 / 32 to contact the mounting surface provided with the mounting groove 112 to bear the force, so as to obtain the load borne by the corresponding suspension bracket, and avoid the mounting surface where the mounting groove 112 is located from contacting the end face of the three-point force sensor 3 around the boss 311, so as to accurately and effectively obtain the load borne by the dynamic suspension under misuse conditions.

[0038] In some embodiments, as Figure 1 and Figure 2 As shown, the second mounting surface 211 is configured to be located above the first mounting surface 111. In this way, the load transmitted from the powertrain 200 side can be transmitted downward to the frame assembly 100 side in the form of pressure, so as to optimize the force transmission direction when the powertrain 200 is installed above the frame assembly 100 and ensure the accuracy of load data collection.

[0039] In some embodiments, as Figure 2 and Figure 3 As shown, one of the force-bearing ends of the three-force sensor 3 is the first force-bearing end 31, and the other force-bearing end is the second force-bearing end 32. The middle part of the first force-bearing end 31 is provided with a first threaded hole 312 opened along the height direction of the vehicle, and the second force-bearing end 32 is provided with at least three second threaded holes 321 opened along the height direction of the vehicle. The at least three second threaded holes 321 are rotationally symmetrically distributed on the second force-bearing end 32 with the axis of the first threaded hole 312 as the center; similarly, one of the first mounting surface 111 and the second mounting surface 211 is provided with a first through hole 113 corresponding to the first threaded hole 312, and the other mounting surface is provided with at least three second through holes 212 corresponding to the second threaded hole 321. In this way, the corresponding force-bearing end and the mounting surface can be fixedly connected by passing a connecting member such as a connecting bolt from one side of the through hole and connecting it to the corresponding threaded hole.

[0040] For example, in this embodiment, there is one first threaded hole 312, four second threaded holes 321, and a first through hole 113 is provided on the first mounting surface 111 corresponding to the first threaded hole 312, and four second through holes 212 are provided on the second mounting surface 211 corresponding to the second threaded hole 321. In this way, a connecting member such as a first bolt 41 can be used to pass through the first through hole 113 from the lower side of the first mounting surface 111 and connected to the first threaded hole 312 to fix the first force-bearing end 31 to the first mounting surface 111; then a connecting member such as four second bolts 42 can be used to pass through the second through hole 212 from the upper side of the second mounting surface 211 and connected to the second threaded hole 321 to fix the second force-bearing end 32 to the second mounting surface 211, thereby simply, quickly and firmly realizing the fixation of the three-force sensor 3 between the first suspension bracket 1 and the second suspension bracket 2.

[0041] Further, if Figure 2 and Figure 3 As shown, a avoidance hole 322 is opened in the middle of the second force-bearing end 32 corresponding to the first threaded hole 312, and the avoidance hole 322 is connected to the first threaded hole 312 along the vehicle height direction, and the aperture of the avoidance hole 322 is larger than the aperture of the first threaded hole 312. In this way, when the first bolt 41 is connected to the first threaded hole 312, it can have a certain movable gap relative to the second force-bearing end 32 at the avoidance hole 322, thereby avoiding contact between the first bolt 41 and the second force-bearing end 32, thereby ensuring the accuracy of load data collection.

[0042] It can be understood that when the above-mentioned force-bearing end 31 / 32 is provided with a boss 311, the above-mentioned first threaded hole 312 can be provided in the boss 311, and the corresponding first through hole 113 is provided in the installation groove 112. By reasonably allocating the installation space, the volume occupancy can be reduced and the connection stability can be improved.

[0043] In some embodiments, as Figure 1 and Figure 2 As shown, the first suspension bracket 1 is extended to one side in the horizontal direction and is provided with a first platform 11, and the second suspension bracket 2 is extended to one side in the horizontal direction and is provided with a second platform 21. At this time, the first mounting surface 111 is limited to the first platform 11, and the second mounting surface 211 is limited to the second platform 21. Through the setting of the first platform 11 and the second platform 21, the three-force sensor 3 can be installed in a horizontally staggered manner, thereby reducing the vertical space occupancy without affecting the load collection, so as to adapt to a compact and narrow installation environment.

[0044] It is understood that the first platform 11 and the second platform 21 can be extended horizontally from the first suspension bracket 1 and the second suspension bracket 2 to either side, leaving sufficient height between the first mounting surface 111 and the second mounting surface 211 to accommodate and satisfy the installation of the three-force sensor 3 along the vehicle height direction. The extension direction and inclination direction can be arranged according to the original suspension bracket setting direction and the installation space between the frame assembly 100 and the powertrain 200, so as to satisfy the horizontal offset installation of the three-force sensor 3. Preferably, the first platform 11 and the second platform 21 can also be provided with reinforcing ribs to increase structural strength, thereby ensuring the accuracy and effectiveness of load collection.

[0045] For example, if Figure 1 and Figure 2 As shown, the first suspension bracket 1 includes a suspension bushing 12 and a bracket body 13, and the suspension bushing 12 is embedded in the bracket body 13. The bracket body 13 and the inner core 121 of the suspension bushing 12 are respectively connected to the outside to achieve vibration reduction through the pad of the suspension bushing 12. The specific connection method and vibration reduction structure are prior art and will not be repeated here. Among them, the bracket body 13 can be detachably fixed to the frame assembly 100, and then the inner core 121 of the suspension bushing 12 is extended outward along the axial direction of the suspension bushing 12 to form or connect the first platform 11 for installing the three-force sensor 3. The second suspension bracket 2 can be designed according to its connection position with the powertrain 200 and the general structure of the original suspension bracket, and the second platform 21 is extended to form or connect to the orientation of the first platform 11, so that the second platform 21 and the first platform 11 are relatively spaced apart along the height direction of the vehicle. In this way, the load on the first platform 11 can be transferred toward the bracket body 13 along the radial direction of the suspension bushing 12 through the inner core 121 of the suspension bushing 12, which conforms to the load transfer path of a normal suspension bracket and ensures the accuracy and effectiveness of load collection.

[0046] Further, if Figure 5 and Figure 6As shown, in another embodiment, the inner core 121 (121' / 121") of the suspension bushing 12 (12' / 12") can be detachably fixedly connected to the frame assembly 100 through a connecting piece such as a bolt, and then the bracket body 13 (13' / 13") is extended outward along the circumference of the suspension bushing 12 (12' / 12") to form or connect the first platform 11 (11' / 11") for installing the three-force sensor 3 (3' / 3"); relative to the arrangement of the previous embodiment, the inner core 121 (121' / 121") of the suspension bushing 12 (12' / 12") of this embodiment 1' / 121") can not only be fixed on one side in the axial direction, but also the bolts can be passed through the axial sides of the inner core 121 (121' / 121") of the suspension bushing 12 (12' / 12") to achieve common support and limitation on both sides in the axial direction, thereby improving the structural stability of the suspension; at the same time, the load borne by the first platform 11 (11' / 11") can be directly transferred to the inner core 121 (121' / 121") along the radial direction of the suspension bushing 12 (12' / 12") toward the axis of the suspension bushing 12 (12' / 12"), thereby ensuring the accuracy and effectiveness of load collection.

[0047] In addition, if Figure 2 、 Figures 4 to 6 As shown, in another embodiment, a power suspension load collection tool is also provided, including a frame assembly 100, a power assembly 200, a left suspension 300, a right suspension 400 and a rear suspension 500, wherein the left suspension 300 connects the power assembly 200 and the frame assembly 100 on one side in the vehicle width direction, the right suspension 400 connects the power assembly 200 and the frame assembly 100 on the other side in the vehicle width direction, and the rear suspension 500 connects the power assembly 200 and the frame assembly 100 on the rear side in the vehicle length direction; since the left suspension 300 and the right suspension 400 are respectively located on both sides in the vehicle width direction, they can collect loads from each other in the vehicle width direction. Sharing, therefore, the left suspension 300 and the right suspension 400 can be the power suspension load collection device described in any of the above embodiments, and can be selected and arranged according to the setting direction of the original suspension bracket and the installation space between the frame assembly 100 and the power assembly 200; and the rear suspension 500 is preferably the power suspension load collection device described in another embodiment above. In this way, at the rear suspension 500, connecting parts such as bolts can be passed through the axial sides of the inner core 121 of its suspension bushing 12 to achieve common support and limitation on both axial sides, thereby avoiding the load at the rear suspension 500 from being transmitted on one side in the axial direction to form shear force, thereby ensuring the accuracy and effectiveness of load collection.

[0048] For example, if Figure 1 and Figure 4As shown, in this embodiment, the bracket body 13 of the first suspension bracket 1 of the left suspension 300 is detachably fixedly connected to the frame assembly 100 on the left side, the inner core 121 of the suspension bushing 12 of the left suspension 300 extends axially to the right and is connected to the first platform 11, and the second suspension bracket 2 of the left suspension 300 is extended to correspond to the first platform 11 and is provided with a second platform 21 for mounting the three-force sensor 3; Figure 4 and Figure 5 As shown, the inner core 121' of the suspension bushing 12' of the first suspension bracket 1' of the right suspension 400 is detachably fixedly connected to the frame assembly 100 on the axial right side, and the bracket body 13' of the right suspension 400 extends rearward along the circumference of the suspension bushing 12' to form a first platform 11'. The second suspension bracket 2' of the right suspension 400 is provided with a second platform 21' corresponding to the first platform 11' for installing the three-force sensor 3'. In this way, the left suspension 300 and the right suspension 400 can share the load applied downward by the powertrain 200 in the vehicle width direction; Figure 4 and Figure 6 As shown, the inner core 121" of the suspension bushing 12" of the first suspension bracket 1" of the rear suspension 500 is detachably fixed to the frame assembly 100 by connecting parts such as bolts, and the bracket body 13" of the first suspension bracket 1" of the rear suspension 500 extends forward along the circumference of the suspension bushing 12" to form a first platform 11", and the second suspension bracket 2" of the rear suspension 500 extends in the direction corresponding to the first platform 11" to form a second platform 21" so as to be spaced relative to the first platform 11" for installing a three-force sensor 3". In this way, bolts can be passed through the axial sides of the inner core 121" of the suspension bushing 12" of the rear suspension 500 and fixed to the frame assembly 100 to achieve common support and limitation on both axial sides, thereby avoiding the load at the rear suspension 500 from being transmitted axially on one side to form shear force, thereby ensuring the accuracy and effectiveness of load collection.
