基于停车位尺寸的汽车后悬长度设计方法研究

The Design Method Study of Vehicle Rear Overhang Based on Parking Space Size

汽车后悬长度是整车设计过程中的一个关键数据,其长度直接影响着整车的定位等级,同时也对整车的空间布置、行驶性能等方面有着直接的影响。目前,汽车后悬尺寸已成为各大厂商在汽车设计之初需要平衡的难点。文章介绍了一种在汽车设计之初,基于停车位的尺寸对车辆后悬长度进行计算校核的方法,详细介绍了该方法的推导过程。该方法适用于所有乘用车类型的车辆后悬校核,可为车辆的后悬长度设计提供一定的参考。

The length of rear overhang is a key data in the design process that directly affects the positioning level of the car.Meanwhile,the layout and performance of the car is also affected by the rear overhang.The rear overhang is now a difficult point for the major manufacturers to balance in the car design process.In this paper,a method is introduced to calculate the length of rear overhang based on the size of parking space at the beginning of the car design.This design method is suitable for all passenger car types,which provides a reference about the rear overhang size for designing.
