The mechanical property is strong: the main structure and the mounting bracket at the upper end of the shock absorber are both designed into box-shaped structures, and the overall mechanical performance meets the mechanical requirements of passenger vehicles.
The manufacturing process is simple: the gantry framework and the floor framework are welded by adopting cut rectangular pipes, and the mounting bracket at the upper end of the shock absorber is welded by adopting cut and bent steel plates. The manufacturing process of the mounting platform of the suspension mainly comprises the processes of cutting, bending, punching, welding, coating and the like, and the 5 types of processes belong to the basic process of mechanical manufacturing and processing.
And (3) universal design: the suspension mounting platform can be used as a front automobile body and a rear automobile body of the minicar through the position adjustment of corresponding arrangement; the universal and modular design thus allows the same piece to be used for the shock absorbers and the swing arms of the front and rear suspensions.
Cost and time reduction: the cost and time of each stage of the passenger car can be effectively reduced through the elements of simplification, modularization and universalization of the structural design of the suspension mounting platform, simplification of manufacturing and processing and the like.
