Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1, a suspension structure for distributed driving, including a supporting frame 1, a rocker arm 2 is fixedly installed in the middle of the upper portion of the supporting frame 1, a damper 3 is fixedly installed in the middle of the bottom of the supporting frame 1, a damping spring 4 is fixedly installed on the surface of the damper 3, a generator 5 is fixedly installed on the upper portion of the damper 3, a double-link rod 6 is arranged on the left side of the supporting frame 1, the double-link rod 6 is fixedly connected with the supporting frame 1 through a pin 7, a top rod 8 is fixedly installed on the lower portion of the double-link rod 6, a connecting claw 9 is fixedly connected to the left side of the double-link rod 6, the two connecting claws 9 are connected together through a tandem shaft 10, a hub shaft 11 is fixedly connected to the middle of the tandem shaft 10, a hub 12 is fixedly installed on the left.

The parallelogram formed by the double connecting rods 6 is a basic structure of distributed suspension, the upper and lower connecting rods in the double connecting rods 6 realize the swinging of the upper and lower degrees of freedom through a bearing or universal joint structure, the structure is simpler and easy to produce and install on the whole, and simultaneously the independent distribution at one end of the automobile can reduce the bumping feeling of the automobile.

The ejector rod 8 is designed on the lower connecting rod, and the swinging force is transmitted to the shock absorber 3 and the damping spring 4 through the rocker arm 2 to realize the function of flexible buffering.

Wherein, ejector pin 8 and rocking arm 2 cooperate each other and can carry out the shock attenuation with the upper and lower power that wheel 13 transmission came, and this collocation structure is different from traditional bumper shock absorber 3 and damping spring 4's position, and the central point that has realized bumper shock absorber 3 and damping spring 4 puts almost the same with the center of wheel 13, has improved the problem that the controllability that the increase of unsprung mass leads to in the distributed drive structure subtracts the branch, because of the reason that damping device puts down simultaneously, has reduced the center of vehicle, has strengthened vehicle controllability.

The structural clearance between the double connecting rods 6 and the bearing forms a structure rotating along with the direction, so that the tail swinging force during high-speed steering can be reduced, and the running stability of the vehicle is improved.

The working principle is that the whole suspension structure is assembled in advance and is installed on an automobile at the same time, when the automobile is subjected to up-down bumping force in the driving process, the force received by the wheels 13 is transmitted to the connecting claws 9 and the double connecting rods 6 from the hub shaft 11 at this time, the double connecting rods 6 are in a parallelogram shape, up-down swinging in a certain range can be realized under the help of the rocker arms 2, the ejector rods 8, the shock absorbers 3 and the shock absorbing springs 4, when the automobile needs to turn, the hub shaft 11 of the wheels 13 can move left and right in the limited height of the tandem shaft 10, and the whole automobile suspension is independently located at one end of the automobile (the whole automobile suspension is more convenient to install by difference and integral, and cannot vibrate together by external force at the same time, and only can disperse force by local action).
