AI Technical Summary

Technical Problem

Existing cab designs struggle to simultaneously satisfy driving comfort, ease of getting in and out of the vehicle, and low wind resistance within a limited space, impacting the vehicle's range and cargo capacity.

Method used

By redesigning the cab layout, positioning the steering wheel and front wheels to create a streamlined structure, optimizing the driver's seating position and door design, and reserving design space to achieve low wind resistance and convenient entry and exit.

Benefits of technology

Within a limited cab length, the design improves driving comfort and ease of getting in and out of the vehicle, while also reducing the drag coefficient, increasing cargo space, and enhancing the vehicle's range and load-carrying capacity.

Abstract

This application relates to a driver's cab, which includes a driver's compartment and a steering mechanism. The driver's compartment has a driver's cabin and includes a front section and side sections located on both sides of the front section. The side sections are provided with wheel wells for engaging with the front wheels and are concentrically positioned with the front wheels. The steering mechanism includes a steering wheel, which is disposed in the driver's cabin. In the X direction, the maximum dimension L4 of the driver's compartment satisfies the following range: 1550mm ≤ L4 ≤ 1950mm. The distance between the center point of the steering wheel and the center point of the wheel well is L11, and the range of L11 satisfies the following range: -65mm ≤ L11 ≤ 335mm. Specifically, L11 takes a negative value when the center point of the steering wheel is located on the side of the wheel well closer to the front section, and a positive value when the center point of the steering wheel is located on the side of the wheel well farther from the front section. The driver's cab in this embodiment can reconstruct the cab layout, reserving design space for a streamlined structure at the front of the cab within a limited space, facilitating a low-drag cab design.
