Detailed Description
Preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative, exemplary, and should not be construed as limiting the scope of the application.
First, terms of top, bottom, upward, downward, and the like are defined with respect to directions in the drawings. They are relative concepts and can therefore vary with the location and use status of the feature. Therefore, these directional terms should not be construed as limiting terms.
Furthermore, it should also be noted that any individual feature described or implicit in the embodiments herein, or any individual feature shown or implicit in the drawings, can still be combined between these features (or their equivalents) to obtain other embodiments of the application not directly mentioned herein.
It should be noted that in different drawings, the same reference numerals indicate the same or substantially the same components.
Fig. 1 and 2 illustrate one embodiment of a suspension architecture assembly of the present application. As shown in fig. 1 and 2, the suspension frame assembly includes a housing 10, a base 20, an elastic member 30, a stopper 40, one or more connectors, and the like.
The housing 10 may define a cavity 11 located therein. The cavity 11 may have an inner wall and the housing 10 has a wall thickness of a predetermined thickness around the cavity 11. In the illustrated embodiment, the cavity 11 may have a generally trapezoidal cross section. In one embodiment, the housing 10 may be an aluminum alloy die cast.
The base 20 may be disposed within the cavity 11 and fixed in position relative to the cavity 11. In one embodiment, the position of the base 20 relative to the housing 10 is changeable. The implementation of the different positions of the base 20 will be described in detail below. In the illustrated embodiment, the base 20 may have a generally inverted trapezoidal profile, and the profile of the base 20 is adapted to fit inside the cavity 11.
The elastic member 30 may be configured to be integrally connected with the base 20. In one embodiment, the elastic member 30 has a vulcanized connection with the base 20. In one embodiment, the elastic member 30 may be formed of natural rubber through vulcanization so as to have a predetermined rigidity. In one embodiment, the resilient member 30 is a suspension main spring. The center position of the suspension main spring is the elastic center of the whole suspension framework component. In fig. 1 and 2, the elastic member 30 is only schematically shown to show its general position. The center of the suspension main spring may be used in connection with a vehicle powertrain, not shown. The elastic member 30 may be connected to the connection member 30. The connector 30 may be part of the main spring structure and connected to other components not shown.
The stopper 40 may be disposed between the base 20 and the inner wall of the housing 10. For example, both sides of the base 20 may be provided with a single stopper 40, respectively. For another example, one side of the base 20 may be provided with a stop, while the other side may not be provided with a stop. The dimensions of each stop 40 may be substantially the same or may be different. In the illustrated embodiment, each stop 40 has a substantially trapezoidal cross section so as to adapt, on the one hand, to the sides of the base 20 and, on the other hand, to the inner wall of the casing 10. In one embodiment, there may be an interference fit between the stop 40 and the base 20. In another embodiment, there may be an interference fit between the stop 40 and the inner wall of the housing 10. In one embodiment, the thickness of the different housings 10 may also correspond to the size of the different stop members 40. In other words, if different housing thicknesses are employed, the dimensions of the corresponding stop 40 are different. The dimensions of the stop 40 may be matched to the thickness of the housing 10 to position the base 20 in a desired location, as desired.
By providing different thicknesses of the housing 10 and employing different stoppers 40, the position of the base 20 can be changed on the basis of the first state shown in fig. 1. For example, the position of the base 20 may be changed to the second state shown in fig. 2. By using other shell thicknesses and other stops, it is also possible to secure the base 20 in more positions. When the position of the base 20 is changed, the position of the elastic member 30 is changed accordingly. This causes the center of the suspension main spring to change accordingly, which can be adapted to different vehicle powertrains.
The suspension frame assembly may also include one or more rail interfaces. In the illustrated embodiment, the lower portion of the housing 10 is provided with bolt holes. The bolt holes are the stringer interfaces in the illustrated embodiment. Each bolt hole is respectively matched with a first bolt hole 101 and a second bolt hole 102 on the longitudinal beam 100 of the vehicle body. In one embodiment, the first bolt hole 101 and the second bolt hole 102 are also referred to as stringer mounting points. The first and second connectors 51, 52 may be used to secure the suspension frame assembly to the body rail 100. In practice, the number of connectors is not limited to the case illustrated, but rather more connectors may be employed. In one embodiment, the connection may be a bolt.
The application also relates to a vehicle comprising a suspension frame assembly as described above. A vehicle body side member 100 may be provided on the vehicle, and bolt holes are provided on the vehicle body side member 100. The bolt holes in the lower portion of the shell 10 may be configured to mate with the bolt holes in the body rail 100 to secure the suspension frame assembly to the body rail 100 via the connectors.
Furthermore, the locomotion assembly is connected with the suspension frame assembly, more specifically with the elastic member 30 and the base 20. In this case, the NTA line of the powertrain may be located at the elastic center of the elastic member 30, so that the powertrain is firmly fixed in place. The closer the elastic center is to the NTA line, the better the vibration isolation performance of the elastic member 30. Thus, such an arrangement also results in improved NVH performance for the vehicle, thereby enhancing the user experience.
Furthermore, by varying the position of the base 20, the suspension frame assembly of the present application may enable a single vehicle platform to be adapted to different powertrains. Such a structure is advantageous in saving development costs and improving cost efficiency. The elastic members 30 may be the same or different for different vehicles.
The suspension framework component and the vehicle have the advantages of simple structure, convenient use, low cost, convenient maintenance and the like. By adopting the suspension framework assembly and the vehicle, the operation efficiency of the vehicle platform can be effectively improved.
The present specification discloses the present application with reference to the accompanying drawings and also enables one skilled in the art to practice the application, including making and using any devices or systems, selecting suitable materials, and using any incorporated methods. The scope of the application is defined by the claims and encompasses other examples that will occur to those skilled in the art. Such other examples should be considered to be within the scope of protection as determined by the claimed subject matter, so long as such other examples include structural elements that are not literally different from the claimed subject matter, or include equivalent structural elements with insubstantial differences from the literal languages of the claimed subject matter.
