Description

Technical Field

[0001] This utility model relates to the field of amphibious vehicle technology, and in particular to a bottom anti-collision protection device for amphibious vehicles. Background Technology

[0002] As a special vehicle capable of operating in both land and water environments, the bottom structure of an amphibious vehicle must simultaneously meet the requirements of load-bearing capacity and driving stability when driving on land, as well as impact resistance and collision prevention when navigating in water. The axle assembly, as the core component connecting the chassis and the wheels (or tracks), has a connection structure design that directly affects the driving safety and service life of the amphibious vehicle. In existing technologies, if a vehicle travels on a bumpy road or experiences a bottom impact, the rigid connection cannot effectively buffer the impact force, which can easily lead to stress concentration at the connection between the axle mounting bracket and the frame. Long-term use may cause bolts to loosen, brackets to deform, or even cause displacement of the axle assembly, affecting the driving stability of the vehicle when moving forward or backward. Although some improvement solutions have added a single shock-absorbing component (such as a spring or rubber block) between the axle and the frame, they have not formed a synergistic buffer structure, and the buffering effect is limited, still unable to solve the stability problem caused by the rigid connection.
