The invention belongs to the field of mining trucks, and particularly relates to a dual-motor three-stage three-intermediate-shaft transmission wheel-side electric drive axle for a mining truck, which comprises a left wheel-side transmission module with a left wheel-side transmission device and a right wheel-side transmission module with a right wheel-side transmission device, a left motor drives the left wheel-side transmission device through a left three-stage three-intermediate-shaft transmission device, and a right motor drives the right wheel-side transmission device through a right three-stage three-intermediate-shaft transmission device. A right motor drives a right wheel edge transmission device through a right three-stage three-intermediate-shaft transmission device; for a large-tonnage mining truck, double-axle driving can be adopted, double motors, three-stage three-intermediate-shaft transmission and wheel edge transmission are adopted for each single axle, the double motors are arranged in the middle and are not biased, the use working condition strength requirement of special requirements of mining truck products can be met, the three-stage three-intermediate-shaft structure is compact, the structure is simple, and the cost is low. Under the condition that the requirements for the axial vacancy size and the ground clearance are met, the requirement for the large speed ratio can be met through three-stage transmission, the requirement for large-torque transmission of the gear strength can be met through the three intermediate shafts, and meanwhile stable and reliable power transmission can be achieved through the three intermediate shafts.

    本发明属于矿用卡车领域,尤其为一种矿用卡车用双电机三级三中间轴传动轮边电驱动桥,包括带有左轮边传动装置的左轮边传动模块、带有右轮边传动装置的右轮边传动模块,左电机通过左三级三间轴传动装置驱动左轮边传动装置,右电机通过右三级三间轴传动装置驱动右轮边传动装置;对于大吨位矿用卡车,可以采用双桥驱动,每根单桥采用双电机+三级三中间轴传动+轮边传动,双电机中间布置且无偏置,可满足矿卡产品特殊需求的使用工况强度需求,三级三中间轴结构紧凑,在满足轴向空置尺寸及离地间隙的需求下通过三级传动可实现大速比的需求,三中间轴可实现大扭矩传递齿轮强度的需求,同时三中间轴可实现动力传递平稳可靠。
