[0092] like Figures 6 to 9 In the third embodiment shown, the suspension arm assembly 20 is a four-ball double wishbone suspension.

[0093] On the basis of the double ball head McPherson suspension in the second embodiment, the suspension arm assembly 20 further includes an upper swing arm 23. Optionally, the upper swing arm 23 is constructed as two connecting rods. Each connecting rod has two connecting ends, and the two connecting ends are respectively connected to the vehicle body and the steering knuckle 22. Optionally, the inner side of the upper swing arm 23 is connected to the vehicle body through a bushing. The outer side of the upper swing arm 23 is connected to the steering knuckle 22. Optionally, the upper swing arm 23 is connected to the upper end of the steering knuckle 22 through a ball joint 221.

[0094] In this embodiment, the arrangement of the lower swing arm 21 and the arrangement of the stabilizer bar fixing portion 13 of the housing 10 are the same as those of the second embodiment, and will not be described in detail here for the sake of brevity.

[0095] In this embodiment, the fixing portion of the housing 10 is disposed on the upper side of the housing 10. Optionally, a plurality of fixing portions are provided. For example, the fixing portions are provided at the front, middle and rear portions of the upper side of the housing 10.

[0096] In this embodiment, the connection point between the housing 10 and the vehicle body is set on the upper side of the housing 10, and the vehicle body fixing portion 11 and the suspension arm fixing portion 12 are located on different sides of the housing 10, so there is little interference with the suspension arm assembly 20. In addition, for the convenience of disassembly and assembly of the suspension arm assembly 20, the suspension arm fixing portion 12 is fixed at the lower position of the suspension arm fixing portion 12.

[0097] like Fig.10 and Fig.11 In the fourth embodiment shown, the suspension arm assembly 20 is a schematic diagram of a double-ball head double wishbone suspension assembly.

[0098] On the basis of the single ball head McPherson suspension in the first embodiment, the suspension arm assembly 20 further includes an upper swing arm 23.

[0100] In this embodiment, the configuration of the fixing portion of the housing 10 is the same as that of the first embodiment, and will not be described in detail here for the sake of brevity.

[0101] In the present application, the types of suspension arm assemblies 20 include but are not limited to single-ball McPherson suspension, double-ball McPherson suspension, double wishbone suspension, and four-ball double wishbone suspension. As long as the suspension arm is directly connected to the housing 10, it falls within the protection scope of the present invention.

[0102] In the present application, by providing a vehicle body fixing portion 11, a suspension arm fixing portion 12 and an optional stabilizer bar fixing portion 13 on the housing 10, the traditional suspension form - the suspension arm is installed on the subframe - is changed to installing the suspension arm and the stabilizer bar on the housing 10, and the subframe can be completely eliminated. The elimination of the subframe not only makes a huge contribution to the weight reduction of the whole vehicle, but also leaves a lot of space. This space can be used to arrange a larger powertrain or battery pack, thereby improving the motor drive power and the vehicle's endurance.

[0103] According to the above, in the solution of the present application, the subframe is eliminated. In other words, the suspension arm assembly and the powertrain can serve as the subframe of the vehicle.
