Abstract

The invention relates to the field of automobile assembly, and more specifically, relates to a method for integrally assembling an automobile chassis. A method for overall assembly of an automobile chassis proposed by the present invention includes the following steps: S1. Based on the deviation parameter, the plane size chain model is used to calculate the success rate of the assembly, and the deviation parameter is adjusted according to the success rate of the assembly until the specified success rate is satisfied, and then enters the step S2; S2, assemble the chassis of the car according to the deviation parameters. The overall assembly method of the automobile chassis proposed by the present invention is based on the overall assembly scheme of multi-level control, comprehensively considers various important deviations, establishes a mathematical model of the success rate of the overall assembly of the chassis based on the plane dimension chain, and realizes the optimal size tolerance distribution , so as to quantitatively optimize the manufacturing and installation process and improve the success rate of assembly.

Description

technical field [0001] The invention relates to the field of automobile assembly, and more specifically, relates to a method for integrally assembling an automobile chassis. Background technique [0002] The vehicle chassis module is the most important module of the vehicle. Figure 1a reveals a schematic diagram of a prior art chassis assembly, such as Figure 1a As shown, the components of the chassis assembly include powertrain, front axle, rear axle, gear mechanism, brake oil pipe, exhaust pipe, front shock absorber and rear shock absorber, etc. [0003] At present, most of the Japanese, Korean, and American car companies adopt the chassis split assembly mode, that is, the chassis parts are split into separate parts and assembled with the car. The chassis split assembly method cannot guarantee the mutual position of the chassis parts. Accuracy, chassis integrity is poor. [0004] Figure 1b reveals the structural diagram of the chassis pallet of the prior art, such as ...
