Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-8, a steering and damping integrated electric drive module comprises a vehicle body 100 and a hub motor 600 with a wheel 400 sleeved on the outer side thereof, and is characterized in that suspension shells 200 are symmetrically installed on both sides of the vehicle body 100, and a steering reduction box 300 is arranged on each suspension shell 200;

the suspension device further comprises a spring shock absorber 270, a suspension base 500 is arranged at the bottom end of the spring shock absorber 270, and the in-wheel motor 600 is installed on a support on the side wall of the base 500;

the top end of the spring damper 270 is connected to the suspension housing 200 through a knuckle 210, a steering motor 220 is disposed in the steering reduction box 300, and the steering motor 220 is used for driving the spring damper 270 to steer.

Further, in the above technical solution, the upper side of the spring damper 270 is fixedly connected with the suspension housing 200 through the knuckle 210 and the second bolt 201, and the lower side of the spring damper 270 is fixedly connected with the suspension base 500 through the first bolt 501. And the steering reduction box 300 is fixedly connected with the suspension housing 200 by a screw 301.

Further, as shown in fig. 6 to 8, the following embodiments are provided:

driving: four driving modules can be installed at four wheel positions of the vehicle, and when the vehicle is driven to move forward, the four in-wheel motors 600 can be respectively driven to rotate so as to enable the wheel 400 to move forward (if electricity is saved, the vehicle can be driven by only two in-wheel motors 600, and both front driving and rear driving can be achieved, so that four-wheel driving/two-wheel driving switching is met).
