Description

technical field [0001] Embodiments of the present invention relate to the technical field of generalized layout design of vehicle platforms, and in particular to a parameterized layout method and equipment for a vehicle powertrain transmission system. Background technique [0002] Vehicles need to pass through rough roads, ditches, ridges and other harsh road conditions during driving, which requires high escape ability and passability of vehicles. All-wheel drive is often used, and all-wheel drive generally realizes power through front and rear transmission shafts. For transmission, in order to ensure that the front and rear drive shafts work reliably and smoothly under various working conditions of off-road vehicles, the absolute and equivalent angles of the drive shaft generally have design limit requirements for the included angle, beyond which the drive shaft will appear The working vibration is large and the noise is large, which in turn causes the problems of reduced ...

Problems solved by technology

However, there are many disadvantages in the actual application of this traditional analysis method for the series design of platform models. It is often necessary to establish multiple sets of assembly models of the powertrain transmission system to analyze and demonstrate the feasibility of the included angle of the drive shaft. The assembly model of the powertrain transmission system occupies a large amount of memory, the manual adjustment workload is large, and it is not easy to quickly switch and compare different schemes. Once the layout parameters are changed, the analysis results need to manually update the assembly benchmark, which is time-consuming and error-prone
