The invention relates to a dual-motor three-mode multi-gear two-shaft gearbox which comprises a first motor, a second motor, an output end and a gearbox module, wherein the gearbox module is composed of eight gears and three synchronizers, six speed ratios are provided through reasonable utilization of gear pairs on the basis of using as few gears as possible, each speed ratio comprises a low-load mode, a medium-load mode and a high-load mode, and non-power-interruption switching under all gears and all modes can be achieved. The mechanism is high in utilization rate and compact in structure, through reasonable arrangement of the gears and the synchronizers, the gearbox is compact in structure, the reuse rate of the gear mechanism is improved, and the design requirements for multiple gears, light weight, compactness and suitability for various working conditions of the electric automobile gearbox can be met.
本发明涉及一种双电机三模式多挡两轴式变速箱,包括第一电机、第二电机、输出端和变速箱模块;其中,所述变速箱模块采用八个齿轮和三个同步器构成,通过齿轮对的合理利用,在使用尽量少的齿轮的基础上,提供六个速比,每个速比包含低负载、中负载和高负载三种模式,并且可以实现全挡位、全模式下的无动力中断切换。本发明机构利用率高且结构紧凑,通过对齿轮和同步器的合理布置,使变速箱结构紧凑,齿轮机构复用率提高,能够满足电动汽车变速箱多挡位、轻量化、紧凑型、适合多种工况的设计要求。
