Problems solved by technology
The problems caused by this positioning and assembly method are: 1. The overall shape of the frame assembly is a parallelogram after the assembly is completed, causing the center line of the frame to shift; 2. The imprint of the front and rear wheels is not on a straight line when the vehicle is running; 3. The ball cage of the constant velocity universal joint is often pulled off; 4. The assembly sequence is from outside to inside, and the assembly efficiency is low

Embodiment Construction
[0026] The present invention mainly uses the "eight reference axes" of the rotation of the upper and lower cross arms of the double wishbone independent suspension structure as the assembly positioning reference of the vehicle frame assembly, and preferentially controls the "eight reference axes". The vehicle frame assembly includes four The beam and the two longitudinal beams are divided into the first beam assembly 1 and the first connecting bracket 101 to form the first beam process assembly 100 and the third beam assembly 3 and the third connecting bracket 301 to form the third beam Assemble the two longitudinal beams with the process assembly 300 as the reference, and the distribution of "eight reference axes" is as follows figure 1 with figure 2 As shown, the method includes the following steps:
[0027] a. The first crossbeam assembly 1 and the first connecting bracket 101 are subassembled to form the first crossbeam process assembly 100, the first crossbeam assembly ...

The invention provides an assembling and positioning method for a framework assembly with a double-cross arm independent-suspension structure. The method is characterized in that 'eight datum axes', based on which an upper transverse arm and a lower transverse arm of the double-cross arm independent-suspension structure rotate, are taken as assembling and positioning reference of the framework assembly and are controlled preferentially; four cross beam assemblies and connecting brackets are assembled independently to form process fittings first, then four cross beams are positioned and assembled to form the process fittings, and the mounting axes of four lower cross arms are controlled; afterwards, the first cross beam process fitting and the third cross beam process fitting are taken as the assembly reference for the assembling and positioning of two longitudinal beams, and the mounting axes of four upper cross arms are controlled. According to the invention, the method has the advantages that the assembling is carried out from inside out, rather than from outside in, the assembling efficiency is improved while the higher assembling precision is ensured; and next, the 'eight datum axes' are controlled preferentially, so that the vehicle stability and safety performance are improved.
Description
technical field [0001] The invention belongs to the technical field of automobile frame assembly assembly, in particular to an assembly and positioning method for a double-wishbone independent suspension structure frame assembly. Background technique [0002] The conventional assembly method of the general automobile frame assembly adopts the conventional longitudinal beam as the positioning reference. First, the process hole of the frame longitudinal beam is used as the reference to locate the longitudinal beam, and then the beam and other parts are sequentially assembled on the longitudinal beam. , relying on the holes on the longitudinal beams to naturally ensure the position of the beams and other components. The problems caused by this positioning and assembly method are: 1. The overall shape of the frame assembly is a parallelogram after the assembly is completed, causing the center line of the frame to shift; 2. The imprint of the front and rear wheels is not on a str...
