A reinforcing plate for a semi-trailer suspension system

Abstract

The utility model relates to the technical field of semitrailer suspension system, disclose a kind of reinforcing plate for semitrailer suspension system, including installation component, the installation component includes mounting plate, the top of mounting plate is fixedly connected with welding plate, the bottom of mounting plate is fixedly connected with connecting frame.The utility model is operated through the operation of double-path parallel connection buffer structure of mounting bracket, third connecting rod, first mounting seat, second connecting seat, first spring damper and second spring damper, gradient conversion and distribution are generated to vertical direction vibration energy and transverse swing inertial force, to realize the step-by-step absorption effect of impact load, the design is decomposed into multiple-stage elastic deformation process by single severe impact, the maximum instantaneous stress of car frame is reduced, and through the operation of composite hinged fulcrum structure of first connecting rod, second connecting rod, rotating seat, mounting bracket is generated controllable swing angular displacement when being loaded.
