Description

Technical Field

[0001] The present invention relates to the technical field of vehicle frames, and in particular to a suspended truss platform and a vehicle. Background Art

[0002] When a rigid truck is in use, the road conditions are usually poor. The cab, power battery and controller carried on the front-end load-bearing platform of the rigid truck are easily subjected to vibration shock. The platform and the frame below the platform are rigidly connected by bolts, and the shock absorption effect is poor. When the vehicle is driving on a bumpy road, the vibration shock to the cab, power battery and controller will directly act on the load-bearing platform, so it is necessary to ensure that the load-bearing platform has a certain impact resistance. Currently, commonly used load-bearing platforms usually use profiles with large wall thickness and large cross-section to ensure the platform's impact resistance. The number of rods that make up the platform is large, and the layout density is large, resulting in a heavy overall weight of the platform and a high manufacturing cost. Therefore, it is necessary to optimize the load-bearing platform and the connection structure between the platform and the frame to improve the shock absorption effect of the load-bearing platform while achieving the overall lightweight of the platform.
