Study On The Cushion-selecting Measure System Of Automobile Rear Axle

The assembly quality of the automobile gear reducer of rear axle is affected mainly by two factors, one is the assembly quality of the drive gear assembly unit of the automobile gear reducer, the other is whether the meshing between the drive gear and the passive gear is good or not. According to these two factors, the paper established cushion-selecting measure system to solve these actual problems.First we carry out detailed analysis and calculation for the previous tightening force of the bearings, then put forward the principle of determining the previous tightening force of the bearings, meanwhile, we offers the theory basis for selecting cushions; In the course of establishing cushion-selecting measure model, we have fully considered the system' s flexibility; Then the paper carries out detailed exposition for the main structure of system, measure principle and measure course.In electrical control part, this paper mainly elaborates the signal-handling circuit of sensor and the switch-input circuit of external control signal; In the design course of software, we adopt DLL method and realizes the using of the interfacing function of the multi-function card in Industrial Control Computer, finally we discuss succinct and utilitarian software interface and each functional modular in detail. The cushion-selecting measure system that this paper puts forward can apply to the assembly of gear reducer of various type rear axle, and it can raise the assembly quality of the gear reducer of rear axle considerably.
