[0034] Lateral reaction bars are typically installed on the axle via a corresponding connecting structure. As the core component connecting the lateral reaction bar and the axle, the reliability of this connection significantly impacts vehicle safety. Currently, the lateral reaction bar connecting structure is usually bolted to the axle. However, prolonged vibration can easily lead to bolt loosening, affecting the reliability of the connection between the lateral reaction bar connecting structure and the axle.
[0035] In response, this embodiment provides a lateral reaction rod connection structure to solve the problem that in the prior art, the lateral reaction rod connection structure is usually connected to the axle by bolts, which is prone to loosening after long-term vibration. This can be used in the field of vehicle technology.
[0036] Reference Figures 1-4 The lateral reaction rod connection structure is used to install on the axle housing 10 of the axle assembly and to mount the lateral reaction rod. One end of the lateral reaction rod has a connection hole. The lateral reaction rod connection structure includes a connection structure body 1. The first end of the connection structure body 1 is welded to the axle housing 10, and the second end is used to fix and install a connecting ball head 2. The connecting ball head 2 is set in the connection hole, thereby fixing the connecting ball head 2 to the axle housing 10 through the connection structure body 1, further connecting the lateral reaction rod to the axle housing 10. The connection between the connection structure body 1 and the axle housing 10 is achieved through welding, which improves the reliability of the connection between the two. The lateral reaction rod is used to keep the vehicle body as balanced as possible, playing a role in lateral stability. Its specific structure and principle are already relatively conventional technologies in the field, and will not be described in detail here. The connection structure body 1 has a welding clearance groove 11, which is located between the first end and the second end. The welding clearance groove 11 is used for welding tools to extend into. By setting the welding clearance groove 11, more operating space can be provided for the operator to weld, facilitating welding operations.
[0037] Continue to refer to Figures 1-4 Two protrusions 12 are provided at the second end of the connecting structure body 1. The connecting ball head 2 is fixedly connected to the connecting rod 21. The two ends of the connecting rod 21 are fixedly connected to the two protrusions 12 respectively, so that the two ends of the connecting rod 21 can be fixed by the two protrusions 12 respectively, so that the connecting rod 21 can be stably installed on the connecting structure body 1.
[0038] Furthermore, the connecting rod 21 and the protrusion 12 are connected by bolts 31 and nuts 32. The bolts 31 pass through the connecting rod 21 and the protrusion 12 in sequence and are threadedly connected to the nuts 32. Specifically, the protrusion 12 is provided with a threaded hole 123, and the bolts 31 are threadedly engaged with the threaded hole 123. The protrusion 12 has a first plane 121 that fits against the connecting rod 21 and a second plane 122 that fits against the nut 32, so that both the connecting rod 21 and the nut 32 can fit against the surface of the protrusion 12, making the connection between the above structures more stable. The second plane 122 is a machined plane to maximize the surface flatness of the second plane 122. Optionally, the first plane 121 is also a machined plane to maximize the surface flatness of the first plane 121.
[0039] Continue to refer to Figures 1-4The outer wall of the first end of the connecting structure body 1 has a flange structure 13. The flange structure 13 is used to weld to the bridge shell 10, thereby increasing the size of the connecting structure body 1 on the side close to the bridge shell 10. Furthermore, the flange structure 13 is wrapped around the outer side of the outer wall of the connecting structure body 1, and the side of the flange structure 13 close to the bridge shell 10 has a smooth surface, and the shape of the surface is adapted to the surface shape of the corresponding part of the bridge shell 10. Thus, after welding, the connecting structure body 1 can be stably welded to the bridge shell 10 through the flange structure 13.
[0040] Continue to refer to Figures 1-4 The main body 1 of the connecting structure is fixedly connected to a wire harness bracket 4, which is used to fix the wire harness. This allows the lateral reaction rod connecting structure to integrate the wire harness bracket 4 while installing the lateral reaction rod, thus fixing the wire harness through the lateral reaction rod connecting structure. Optionally, the main body 1 of the connecting structure has a wire harness bracket connecting part 14, which is used to fix the wire harness bracket 4. A through hole is formed between the wire harness bracket connecting part 14 and the wire harness bracket 4 for the wire harness to pass through, allowing the wire harness to be installed between the wire harness bracket connecting part 14 and the wire harness bracket 4, restricting the position of the wire harness, and providing some protection for the wire harness through the wire harness bracket connecting part 14 and the wire harness bracket 4. Further, the wire harness bracket 4 is fixedly connected to the wire harness bracket connecting part 14 by a wire harness bracket connecting screw 33. The wire harness bracket connecting part 14 has a wire harness bracket connecting port 141, through which the wire harness bracket connecting screw 33 passes and threadedly engages with the wire harness bracket connecting port 141.
[0041] Continue to refer to Figures 1-4 The main body of the connecting structure 1 is provided with a weight reduction groove 15, so as to reduce the weight of the main body of the connecting structure 1 as much as possible. Optionally, the main body of the connecting structure 1 is a shell structure and is integrally cast.
[0042] Continue to refer to Figures 1-4 The weight reduction groove 15 has an opening 151, and the opening 151 is located on the end face of the first end of the connecting structure body 1, so that the opening 151 of the weight reduction groove 15 is set on the side for welding with the bridge housing 10, and the opening 151 can be hidden after welding.
[0043] This embodiment also provides an axle assembly, including the aforementioned lateral reaction rod connection structure, and an axle housing 10. The lateral reaction rod connection structure is installed on the axle housing 10. In this lateral reaction rod connection structure, the connecting ball head 2 is fixedly installed on the axle housing 10 through the connecting structure body 1, further connecting the lateral reaction rod to the axle housing 10. The connecting structure body 1 and the axle housing 10 are connected by welding, which improves the reliability of the connection between the two. In addition, by setting the welding clearance groove 11, more operating space can be provided for the operator to weld, which facilitates the welding operation.
[0044] Continue to refer to Figures 1-4 The bridge housing 10 includes a bridge sleeve 101 and two bridge tubes 102 respectively disposed at both ends of the bridge sleeve 101. A lateral reaction rod connecting structure is installed on the bridge sleeve 101. Optionally, the bridge sleeve 101 includes a protrusion 1011 and two transition portions 1012 respectively disposed at both ends of the protrusion 1011. The two transition portions 1012 are respectively connected to the two bridge tubes 102. That is, in the bridge housing 10, one bridge tube 102, one transition portion 1012, the protrusion 1011, the other transition portion 1012, and the other bridge tube 102 are sequentially connected. The upper surface of the protrusion 1011 is a plane, and the transition portion 1012 is used to smoothly transition between the protrusion 1011 and the bridge tube 102. The lateral reaction rod connecting structure is installed on one of the transition portions 1012.
[0045] This embodiment also provides a vehicle, including the above-mentioned axle assembly, and also includes a lateral reaction rod. One end of the lateral reaction rod has a connecting hole, and a connecting ball head 2 is disposed in the connecting hole, thereby reliably connecting the lateral reaction rod to the axle housing 10.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
