The invention discloses an electric forklift driving system which comprises a reduction gearbox and a motor, the output end of the motor is connected with the reduction gearbox, and the reduction gearbox comprises a wet mechanical braking system, a first-stage speed reducer and a second-stage speed reducer. Through the independent double-drive system, the whole machine is more convenient to assemble and disassemble, and time is saved; besides, a circulating cooling water pipe is additionally arranged in the shell to cool the first-stage speed reduction system, the second-stage speed reduction system and the wet type mechanical braking system, the problem that the interior of the large-tonnage forklift is overheated during high-strength operation is solved, the transmission and braking stability is improved, and the fatigue life of a product is guaranteed; meanwhile, the brake rod with a compression spring structure is designed, so that the negative brake function of the vehicle is realized, and the vehicle is safer and more reliable during working; the shell and the cover plate which are made of aluminum alloy are adopted, so that the driving system is lighter, and the energy consumption of the vehicle is improved.

    本发明公开了一种电动叉车驱动系统,包括减速箱和电机,所述电机输出端与减速箱连接,所述减速箱包括湿式机械制动系统、一级减速和二级减速。本发明通过独立的双驱系统在整机装配和拆卸方面也更加便利、节省时间;此外,在壳体内部增加了循环的冷却水管对一级减速、二级减速和湿式机械制动系统进行冷却,避免大吨位叉车高强度作业时内部过热的问题,提高了传动和制动的稳定性,保证了产品的疲劳寿命;同时通过设计带压缩弹簧结构的制动杆,实现了车辆负制动功能,使得车辆在工作时更加安全可靠;通过采用铝合金材质的壳体和盖板,使得驱动系统更加轻便,改善了车辆的能耗。
