( Ningbo UMD Automatic Transmission Co. , Ltd. , Ningbo Zhejiang 315800, China) Abstract: Based on the case of a dual clutch transmission (DCT) housing design, according to the CAE analysis results, the influencing
factors were discussed. The results show that increasing the clearance between the parking pressure plate and the parking shaft can essentially
change the direction of the force and effectively reduce the force acting on the detent pin. Through finite element analysis, the stress and
strain of the corresponding mounting hole and locating pin hole on the transmission shell under the condition of parking abuse and parking 30%
slope with different clearance between the parking axle and the parking pressing plate are simulated. The simulation analysis shows that the
stress and strain are controlled within the reasonable design range, which improves the reliability of the transmission design.
