Embodiment Construction
[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] An embodiment of the present invention provides a rear subframe of an electric vehicle, referring to figure 1 , figure 2 As shown, it includes a front cross beam 11 and a rear cross beam 12 arranged at intervals, and a first longitudinal beam portion 20 and a second longitudinal beam portion 30 connected between the front cross beam 11 and the rear cross beam 12 . In the height direction of the vehicle, the first side member 20 is higher than the second side member 30 .
[0031] When the rear sub-frame is installed on the automobile, along the front and rear direction of the automobile, the front beam 11 is located at the front side, and the rear beam 12 is located at the rear side. The first longitudinal beam part 20 is used for...

The invention discloses a rear auxiliary vehicle frame and an electric vehicle. The rear auxiliary vehicle frame comprises a front cross beam and a rear cross beam which are arranged in a spaced mode. The rear auxiliary vehicle frame is characterized in that the rear auxiliary vehicle frame further comprises a first longitudinal beam part and a second longitudinal beam part which are distributed in the height direction; the first longitudinal beam part is used for mounting an upper swing arm in a suspension system, and the second longitudinal beam part is used for mounting a lower swing arm in the suspension system; the two ends of each longitudinal beam are connected with the front cross beam and the rear cross beam correspondingly; and a first motor suspended support is mounted on each longitudinal beam of the first longitudinal beam part and located at the end, close to the rear cross beam, of the longitudinal beam to serve as a first mounting point for a motor. Compared with an existing rear auxiliary vehicle frame, a pair of the left longitudinal beam and the right longitudinal beam of the rear auxiliary vehicle frame are additionally arranged, and accordingly more mounting points are provided for the motor as well as a transverse pull rod, a stabilizing rod and the swing arms.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a rear auxiliary frame and an electric automobile. Background technique [0002] The motor is an important part of an electric vehicle. The motor of an existing electric vehicle is usually installed in the body or at the front of the vehicle. For a rear-drive vehicle, the distance between the motor and the rear drive shaft is relatively long, which is not conducive to the transmission of power. effectiveness. [0003] Mounting the motor on the rear subframe reduces the distance between the motor and the rear drive shaft. However, the existing rear sub-frame needs to provide installation points for tie rods, stabilizer bars, swing arms, etc., and the remaining space is insufficient to provide installation points for the motor. Contents of the invention [0004] The problem solved by the invention is that the existing rear sub-frame cannot provide installation points for the motor dr...
