Abstract: Based on the development practice of a pure level station, this paper summarizes the necessary input, platform expansion strategy and key factors to be considered in the development of a new pure level station. The selection suggestions are obtained by comparing the layout scheme. The results show that the A-arm McPherson can obtain larger battery pack layout space than A-arm rear McPherson suspension. For the layout scheme L113 in front of the motor and steering gear layout shaft and the motor layout in front of the steering gear layout shaft, it is relatively smaller, which can improve the utilization rate of the crew cabin space. The rear motor of the rear motor arrangement can effectively improve the footstep space of three rows of human bodies; Compared with the traditional horizontal air conditioning box, split air conditioning box and longitudinal air conditioning box are conducive to the arrangement of the queen's first officer, but they have different degrees of influence on the arrangement of high voltage devices in the front cabin.

Key words: Input for platform development; Platform expansion strategy; Suspension structure selection; Drive form selection; Motor selection and layout; Steering gear arrangement; Air conditioning box selection and layout
