Abstract
The automobile universal transmission device is in the automobile transmission system important constituent,is located between the gear box and the driving axle . Generally by the universal joint, the drive shaft and the middle supporting is composed. The universal joint energy conservation realization changes the angle power transmission;Transmit the torque of the gear box to the transaxle with drive shaft;The middle supporting can compensate the drive shaft axial and the angle direction in the wiring error and the vehicles travel process because the engine flees moves the displacement which or distortions and so on frame causes. The rotary transmission device function is in the automobile travel process, the included angle and the mutual position changes between the revolution axis in the axis between to transmit the power frequently.
This article mainly is carries on the design to the automobile cross shaft type rotary transmission device. According to vehicles exploitation conditions and vehicles parameter, according to transmission system design procedure and request, Mainly has carried on following work: Mainly has carried on following work choice correlation design variable mainly is: Cross axle, universal joint, drive shaft, middle supporting parameter determination, and has carried on the unit design mainly is: Cross axle design, universal joint design, drive shaft design as well as middle supporting design and so on. And to designs the rotary transmission device through the finite element Pro/E and ANSYS software to carry on the structure analysis, Carries on the improvement design according to the analysis result to the rotary transmission device to obtain the reasonable design proposal.
Keywords: Universal Transmission Device; Cross Axle; Universal Joint; Transmission shaft; Finite Element Analysis
