The invention discloses a vehicle chassis structure, which relates to the technical field of vehicle frames, is particularly suitable for a three-wheel motor vehicle, and comprises a bottom main support extension longitudinal beam. Front wheels are arranged in a rectangular area defined by chassis assemblies such as a bottom main support extending longitudinal beam, a top main support longitudinal beam, a main connecting cross beam and a bottom connecting cross beam through a front suspension assembly, and a three-wheel motor vehicle with one front tire and two rear tires in the layout mode is formed. The suspension stress of the front wheel can adapt to different driving requirements and road conditions, a better braking scheme can be selected for the vehicle through the front brake disc, and under the condition that the whole chassis is not changed, the tire layout is changed into the two-in-front one-in-back mode according to the installation operation requirements, so that the installation efficiency is improved. Therefore, two tire layout forms of'one tire in front and two tires in back 'and'two tires in front and one tire in back' are realized, modularized general replaceable operation can be realized, quick and convenient configuration change is facilitated, the production efficiency is effectively improved, and the manufacturing cost is reduced.

    本发明公开了一种车辆底盘结构,涉及车辆车架技术领域,尤其适用于三轮机动车,包括底主撑延长纵梁,通过在前悬挂组件配合下,利用前悬挂组件将前轮布置于底主撑延长纵梁、顶主撑纵梁、主连接横梁和底连接横梁等底盘组件合围的矩形区域中,形成前一后二轮胎布局形式的三轮机动车,通过改变悬挂方式,使得前轮的悬挂受力能够适应不同的驾驶需求和路况条件,并通过前置刹车盘能为车辆选择更优的刹车方案,在整体的底盘不变的情况下,根据安装作业需求,将轮胎布局改为前二后一的形式,由此实现“前一后二”和“前二后一”两种轮胎布局形式,可实现模块化的通用可调换作业,便于快速、便捷地配置变更,有效提高生产效率、降低制造成本。
