The invention discloses an electric forklift double-drive system which comprises a wet type mechanical brake device, a first-stage reduction gear structure and a second-stage planetary reduction structure, and the wet type mechanical brake device is installed between the first-stage reduction gear structure and the second-stage planetary reduction structure. The second-stage planetary speed reduction structure is rotationally connected with the first-stage speed reduction gear structure through the wet type mechanical braking device, the first-stage speed reduction gear structure is connected with the output end of the motor, the second-stage planetary speed reduction structure comprises a planet carrier, and a gear ring is installed on the inner side face of the planet carrier. The secondary planetary speed reduction structure is arranged on the outer side of the tire rim mounting surface or is arranged close to the outside, and compared with a conventional speed reduction box in which the secondary planetary speed reduction structure is arranged on the inner side of the tire rim mounting surface, the speed reduction box has the advantages that the size of L1 is greatly reduced, so that the width of a whole vehicle is effectively reduced, and the trafficability of the whole vehicle is better.

    本发明公开了一种电动叉车双驱系统,包括湿式机械制动装置、一级减速齿轮结构和二级行星减速结构,所述湿式机械制动装置安装于一级减速齿轮结构和二级行星减速结构之间,所述二级行星减速结构通过湿式机械制动装置与一级减速齿轮结构转动连接,且一级减速齿轮结构与电机输出端连接,所述二级行星减速结构包括行星架,所述行星架内侧面安装有齿圈。本发明通过将二级行星减速结构置于轮胎轮辋安装面的外侧或靠外部放置,对比常规的减速箱设计中将二级行星减速结构置于轮胎轮辋安装面的内侧,好处是极大缩减了L1的尺寸,从而有效的减少整车的车宽,整车通过性会更佳。
