Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and more specifically, relates to a suspension structure and an automobile with improved reliability and durability. Background Art

[0002] The suspension bushing structure of pure electric corporate vehicles (including taxis) generally has no special structural design compared to private vehicles. Since corporate vehicles (including taxis) have a high annual mileage and need to be replaced frequently for after-sales service, it is necessary to improve the durability of the suspension in order to reduce after-sales maintenance.

[0003] The suspensions currently used on vehicles all improve durability by increasing the size of a single suspension. However, the size of a single suspension is too large, and there is a cantilever structure installed, resulting in poor local modal properties, which will affect the NVH performance of the entire vehicle. In addition, the suspension bushings are arranged in the subframe frame beam, and the structure generally adopts a press-fit integration method, which makes it expensive to replace the bushings. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the existing technology and provide a suspension structure and a car with improved reliability and durability.

[0026] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] The utility model provides a suspension structure with improved reliability and durability, comprising:

[0028] Two rear suspension assemblies are respectively arranged on both sides of the connection of the subframe;

[0029] A suspension bracket is provided on one side of the exterior of the two rear suspension assemblies;

[0030] The fixing bolts pass through the two rear suspension assemblies and the subframe, and are connected to the suspension bracket.

[0031] Specifically, two rear suspension assemblies are provided in the suspension structure, and the two rear suspension assemblies are installed from both sides of the subframe, and then the rear suspension assembly is connected to the subframe, and finally the fixing bolts are passed through the two rear suspension assemblies at the same time, and the tail ends of the fixing bolts are connected to the suspension bracket. In this way, when the suspension bracket is connected to the motor, the rigidity of the local structure can be improved, and the vibration of the motor can be effectively isolated. By jointly supporting the suspension bracket through the two rear suspension assemblies, the force on the rear suspension assembly can be reduced, and the durability of the suspension rubber of the suspension assembly can be greatly improved.

[0032] Optionally, the rear suspension assembly includes a body bracket and a suspension bushing, and the suspension bushing is arranged inside the body bracket.

[0033] Optionally, the body bracket is a welded structure, and the suspension bushing is a vulcanized structure.

[0034] Specifically, the rear suspension assembly in this suspension structure utilizes an existing suspension structure. The outer periphery is formed by welding stamped metal parts together, while the internal suspension bushing is formed through a vulcanization process. Finally, the suspension bushing is press-fitted onto the main body bracket to form the rear suspension assembly. Using an existing suspension structure to assemble the suspension structure proposed in this application effectively reduces the economic cost of the suspension structure.

[0035] Optionally, a mounting hole is provided at the connection of the sub-frame, the mounting hole is cylindrical, and the two rear suspension assemblies are embedded in the mounting hole from both sides along the axis direction of the mounting hole.

[0036] Optionally, a flange is provided on the periphery of the rear suspension assembly, and the flange fits against the outer peripheral surface of the mounting hole.

[0037] Optionally, the flange is provided with a plurality of bolt holes along the circumference, and the bolt holes are connected to the sub-frame via mounting bolts.

[0038] Optionally, the number of bolt holes is not less than four.

[0039] Specifically, the outer periphery of the two rear suspension assemblies is circular, and the mounting holes of the subframe are cylindrical. The two rear suspension assemblies are installed from both ends of the mounting holes respectively. When the flanges of the rear suspension assembly are in contact with the outer peripheral surfaces of the mounting holes, it indicates that the rear suspension assembly is snap-fitted and installed in place in the mounting holes. Then, the flanges are connected to the subframe by mounting bolts, so that the rear suspension assembly can be installed on the subframe. Since the structural dimensions of the two rear suspension assemblies are the same, the dimensions of the mounting holes and the rear suspension assemblies match, so that the rear suspension assembly is snap-fitted and installed in the mounting holes without any adjustment, and the two rear suspension assemblies are set in a centered manner.

[0040] Optionally, a through hole is provided at the center of the rear suspension assembly, and the fixing bolt is provided in the through hole.

[0041] Optionally, the suspension bracket is a casting structure, a threaded hole is provided on the suspension bracket, and a fixing bolt is connected to the threaded hole.

[0042] Specifically, after the two rear suspension assemblies are installed with the subframe, the through holes of the two rear suspension assemblies are connected, and the fixing bolts are passed through the two through holes and screwed to the suspension brackets, thus completing the installation of the entire suspension structure. When the suspension bracket is connected to the motor, the vibration of the motor is buffered by the suspension bushings of the two rear suspension assemblies, and both rear suspension assemblies are installed in the mounting holes of the subframe, without expanding the occupied space.

[0043] The utility model also provides an automobile, comprising the above-mentioned suspension structure with improved reliability and durability.

[0044] Specifically, under the trend of lightweight and compact layout, installing the suspension structure on the subframe can not only improve the durability of the suspension rubber, but also effectively control the occupied space, which is beneficial to the layout space of the entire vehicle; the suspension structure adopts two independent suspension assemblies, which can distribute the force of the suspension bracket to the two suspension assemblies.
