Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a frame crossbeam assembly and a vehicle with the frame crossbeam assembly. Background Art

[0002] The integral bridge type five-link suspension is widely used in off-road vehicles. With the frame beam chassis, the vehicle has strong off-road performance. The upper thrust rod mounting bracket of the frame is an important connection structure, and its structural strength is directly related to the off-road performance of the whole vehicle. The upper thrust rod mounting bracket is a key component used to connect the upper thrust rod and the frame. The strength of the mounting bracket structure has a great influence on the overall connection strength.
