The invention relates to a modular front suspension beam structure of a passenger car. The modular front suspension beam structure of the passenger car comprises a front-suspension and front-section beam assembly, connecting longitudinal beam assemblies and a front-suspension and rear-section beam assembly, wherein the front-suspension and front-section beam assembly, the connecting longitudinal beam assemblies and the front-suspension and rear-section beam assembly are arranged in sequence from front to back. An upper thrust bearing assembly is installed on the middle section of the front-suspension and front-section beam assembly. A lower thrust bearing assembly is installed at the bottom of the front-suspension and front-section beam assembly. The connecting longitudinal beam assemblies include the left connecting longitudinal beam assembly and the right connecting longitudinal beam assembly, and the left connecting longitudinal beam assembly and the right connecting longitudinal beam assembly are symmetrically arranged. A left air bag support assembly is installed on the left side of the left connecting longitudinal beam assembly. A right air bag support assembly is installed on the right side of the right connecting longitudinal beam assembly. A middle reinforcing beam assembly is connected between the upper end of the middle section of the left connecting longitudinal beam assembly and the upper end of the middle section of the right connecting longitudinal beam assembly. A transverse thrust bearing support assembly is connected between the lower end of the middle section of the left connecting longitudinal beam assembly and the lower end of the middle section of the right connecting longitudinal beam assembly. The modular front suspension beam structure of the passenger car has the characteristics that the universal strength is high, the labor intensity is low, the production cycle is short, and the space utilization rate is high; and the requirement for lightweight of the passenger car is met.
Description
technical field [0001] The invention relates to the technical field of passenger cars, in particular to a modular front suspension beam structure of a passenger car. Background technique [0002] Due to its structural strength and good passive safety, fully loaded buses are widely used in current high-end large buses. Since the frame of a full-loaded bus is an integral truss-type closed-loop structure, its main body is welded by a large number of small rectangular tubes. Therefore, full-loaded buses also have high welding labor intensity, heavy workload, and welding accuracy that requires various tooling guarantees. difficulty. On the frame of a bus, the most difficult welding and the highest precision requirements are the front and rear suspension structures. For buses equipped with the same front suspension but different, due to its full-load integral design feature, the front suspension sections are also different, and different tooling guarantees are also required, whi...
