Steering Knuckle, etiam ut 'ram angle ", est unus de momenti partes automobile steering pontem, quod potest facere currus currere stabiliter et transferre directionem peregrinatione sensitive. Et munus in gubernaculo tunica est transferre et ferre onus de fronte de currus, firmamentum et eiciam in fronte rota ad gyrari circa kingpin et facere currus vicissim. In driving statum currus, quod habet variabilis impulsum onus, ergo non requiritur ad excelsum vires, in gubernaculo histriones per tres bushings et duo seras et corpus connectit et per LABIS et in fregit. Cum vehiculum est iter ad altum celeritatem, vibrationis traducitur per viam superficiem ad gubernaculo tires per coronas est principalis elementum considerari in analysis. In the calculation, the existing vehicle model is used to apply 4G gravitational acceleration to the vehicle, and the support force of the three center points of the bushing of the steering knuckle and the center points of the two bolt mounting holes is calculated as the applied load, and the freedom of all the nodes on the end face of the flange connecting the brake system is constrained.
