Abstract

The invention relates to the field of automobile assembly, in particular to an automobile chassis integral assembling method. The automobile chassis integral assembling method comprises the followingsteps: S1, calculating an assembling success rate by adopting a plane dimension chain model based on a deviation parameter, adjusting the deviation parameter according to the assembling success rate until the deviation parameter meets a specified success rate, and then entering the step S2; and S2, assembling the automobile chassis according to the deviation parameter. According to the automobilechassis integral assembling method, various important deviations are comprehensively considered based on an integral assembling scheme of multi-stage control, a mathematical model of the integral assembling success rate of the chassis based on a plane dimension chain is established, optimal dimension tolerance distribution is achieved, and therefore manufacturing and installing links can be quantitatively optimized, and the assembling success rate is increased.

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 ...
