[0027] Figure 1 and Figure 2 A suspension assembly according to an embodiment of the present invention is schematically illustrated. Reference is made below. Figure 1 and Figure 2 A suspension assembly according to an embodiment of the present invention is described.

[0028] like Figure 1 and Figure 2 As shown, the suspension assembly 10 according to an embodiment of the present invention includes a suspension device 100 and a roller bearing 200 connected to the suspension device 100. It can be understood that the function of the suspension device in this invention is to transmit forces and torques acting between the wheels and the vehicle frame, and to buffer the impact forces transmitted from uneven road surfaces to the vehicle frame or body, and reduce the resulting vibrations, so as to ensure that the vehicle can drive smoothly. Continuing to refer to... Figure 2 A suspension device 10 according to an embodiment of the present invention is described. For example... Figure 2 As shown, the roller bearing 200 is fixedly connected to the suspension device 100 at its first shaft end 210, and the roller bearing 200 will be fixedly connected to an external component (which may be) at its second shaft end 220 opposite to the first shaft end 210. Figure 3 The vehicle chassis shown in the diagram, and the suspension system 100 are configured to rotate together with one of the inner and outer rings of the roller bearing 200. Simultaneously, the external component is configured to rotate together with the other of the inner and outer rings of the roller bearing, thus achieving relative rotation between the suspension system (and the wheels) and the external component. This will be explained below with reference to... Figure 3 To provide a more detailed description.

[0029] Figure 3 A suspension system according to an embodiment of the present invention is illustrated schematically. Reference is made below. Figure 3 A suspension system according to an embodiment of the present invention is described.

[0030] like Figure 3 As shown, the suspension system 1 according to an embodiment of the present invention includes Figure 1 and Figure 2 The suspension assembly 10 and vehicle chassis 20 are shown in the diagram. As mentioned above, the vehicle chassis 20 is configured as the aforementioned external component and is fixedly connected to the roller bearing 200 at the second shaft end 220 of the roller bearing 200.

[0031] exist Figure 3 In the illustrated embodiment, as an example, the roller bearing 200 is configured as a double-row tapered roller bearing, and as shown... Figure 3 As shown, the roller bearing 200 includes an inner ring 201, an outer ring 202, and rolling elements 203. The suspension device 100 is configured to rotate with the inner ring 201 of the roller bearing 200, and the vehicle chassis 20 is configured to rotate with the outer ring 202 of the roller bearing 200, which will be described in detail below.

[0032] like Figure 3 As shown, the suspension assembly 10 also includes a first connector 400 for connecting the roller bearing 200 to the suspension device 100. The first connector 400 may consist of two cylindrical sections (401, 402). Specifically, the first connector 400 includes a first connecting section 401 that connects to the inner ring 201 of the roller bearing 200. The first connecting section 401 is constructed as a cylindrical section and connects to the inner surface of the inner ring 201 of the roller bearing 200. For example, the first connecting section 401 may have an interference fit with the inner ring 201 of the roller bearing 200. Additionally, the first connector 400 includes a first flange 402, and a first fastener (e.g., a bolt) is provided at the first flange 402 for securing the first connector 400 to the suspension device 100. Specifically, the first fastener secures the first connector 400 to the upper end of the elastic element of the suspension device 100, thereby fixing the inner ring 201 of the roller bearing 200 to the suspension device 100. However, this is merely an example; as another alternative embodiment, the first connector may be integrally formed with the suspension device.

[0033] Continue to refer to Figure 3The suspension assembly 10 also includes a second connector 500 for connecting the roller bearing 200 to the vehicle chassis (external component) 20. This second connector 500 may integrally comprise three cylindrical sections (an upper flange, a lower flange, and a cylindrical section between them). Specifically, the second connector 500 includes a second connecting section 501 that connects to the outer ring 202 of the roller bearing 200. This second connecting section 501 may be constructed as a cylindrical section and connects to the outer surface of the outer ring 202 of the roller bearing 200. For example, the second connecting section 501 may have an interference fit with the outer ring 202 of the roller bearing 200. Additionally, the second connector 500 includes a second flange 502, and a second fastener (e.g., a bolt) is provided at the second flange 502 for securing the second connector 500 to the vehicle chassis 20, thereby fixing the outer ring 202 of the roller bearing 200 to the vehicle chassis 20. Figure 1 The diagram clearly shows that a plurality of bolts are provided circumferentially at the second shaft end 220 of the roller bearing 200 for securely fixing the second shaft end 220 of the roller bearing 200 to the vehicle chassis 20. However, this is merely an example; as another alternative embodiment, the second connector may be integrally formed with the vehicle chassis.

[0034] As an example of the present invention, the suspension assembly 10 may further include a first baffle 310 and a second baffle 320. Figure 3 As shown, the first baffle 310 is integrally formed with the first connector 400, that is, the first baffle 310 is one end of the first connector 400; the second baffle 320 is fixed to the first connector 400 by, for example, screws; it can be understood that the first baffle 310 is disposed between the first shaft end 210 of the roller bearing 200 and the suspension device 10 to enclose the roller bearing 200 at the first shaft end 210, and the second baffle 320 is disposed between the second shaft end 210 of the roller bearing 200 and the vehicle chassis 20 to enclose the roller bearing 200 at the second shaft end 210. This advantageously ensures the working environment of the roller bearing 200.

[0035] In addition, such as Figure 3 As shown, as an example, the second connector 500 is provided with a guide groove 503 (annular groove), and the first connector 400 is provided with a protrusion 403 located in the guide groove 503 to guide the relative rotation between the first connector 400 and the second connector 500.

[0036] Therefore, in this invention, a roller bearing is provided between the suspension assembly and the vehicle chassis. The roller bearing is fixedly connected to the suspension assembly at its first axle end and fixedly connected to the vehicle chassis at its second axle end opposite to the first axle end. The suspension assembly is configured to rotate with one of the inner and outer rings of the roller bearing, and the vehicle chassis is configured to rotate with the other of the inner and outer rings of the roller bearing. Thus, the suspension assembly and suspension system of this invention can achieve rotation between the vehicle chassis and the wheels via the roller bearing, thereby providing the advantages of a large steering range and a small space requirement during steering operations.

[0037] As mentioned above, although exemplary embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above, and the scope of protection of the present invention should be defined by the claims and their equivalents.
