The invention discloses a speed reducer, a driving module, a driving axle and a forklift. The speed reducer is used for being connected with a power source to transmit driving force and comprises a planet carrier and a gear ring. The planet carrier can be in driving connection with a differential mechanism of the vehicle and can rotate or be braked; the gear ring can be in driving connection with a differential mechanism of a vehicle, the planet carrier is arranged in an inner ring space of the gear ring, and the gear ring can rotate or be braked; the gear ring is driven to rotate by braking the planet carrier so that the driving force can be transmitted to the differential mechanism, or the planet carrier is driven to rotate by braking the gear ring so that the driving force can be transmitted to the differential mechanism, and different gear positions can be achieved by replacing different transmission ratios. By optimizing the structure of the speed reducer, the speed reducer can change the transmission ratio, output driving force at different gears and select different gears according to actual working conditions, so that the driving efficiency is improved, and the purpose of saving energy consumption is achieved.

    本发明公开了一种减速器、驱动模块、驱动桥和叉车。减速器用于连接动力源以传递驱动力,包括:行星架和齿圈;行星架能够与车辆的差速器驱动连接,行星架能够旋转或被制动;齿圈能够与车辆的差速器驱动连接,行星架设置于齿圈的内环空间,齿圈能够旋转或被制动;其中,通过制动行星架使得齿圈被驱动旋转从而向差速器传递驱动力,或者通过制动齿圈使得行星架被驱动旋转从而向差速器传递驱动力,以更换不同的传动比实现不同档位。本发明通过优化减速器的结构,使得减速器能够改变传动比,实现不同档位输出驱动力,根据实际工况选择不同的档位,从而提高了驱动效率,达到节省能耗的目的。
