The invention discloses an integral drive-by-wire electric chassis which comprises a walking system, a braking system, a steering system, a power system, an electrical system and a hydraulic system. The braking system adopts four-wheel oil brake braking and adopts line control braking under the intelligent driving condition, and an electromagnetic band-type brake is used for parking; the front axle is a mechanical electric power-assisted steering axle, the rear axle is a driving hydraulic power-assisted steering axle, four-wheel steering can be achieved, split type battery design is adopted in a power system, a battery cell is located in the middle of a girder, and battery management systems (BMS) are located on the two sides of a frame. The chassis of the whole machine is suspended and damped, driving is comfortable, brake-by-wire is stable and reliable, four-wheel steering is flexible, a split battery pack is adopted, maintenance is convenient, and seamless switching between manned driving and intelligent driving can be achieved.

    本发明公开一种整体式线控电动底盘,包括:行走系统、制动系统、转向系统、动力系统、电气系统、液压系统,行走系统为板簧+阻尼减震;制动系统为四轮油刹制动,智能驾驶情况下为线控制动,电磁抱闸进行驻车;前桥为机械电助力转向桥,后桥为驱动液压助力转向桥,可实现四轮转向,动力系统中采用分体式电池设计,电芯位于大梁中间,电池管理系统(BMS)位于车架两侧;整机底盘悬挂减震驾驶舒适,线控制动稳定可靠,四轮转向机动灵活,分体式电池组,维护便捷,并可在有人驾驶、智能驾驶之间无缝切换。
