Problems solved by technology

[0002] At present, most electric forklift transmission systems directly use electric motors instead of internal combustion engines as the power source, retaining the transmission system (transmission shaft, final reducer, half shaft) of traditional internal combustion engine forklifts; the direction of power transmission is perpendicular to the wheel hub, that is, the axis of the wheel; and the traditional The wheel-side planetary reducer drives the wheel-side reducer shell through the planet carrier, and the wheel-side reducer shell drives the wheel hub. The structure is complex, the mechanical efficiency is low, and the economy is poor.

Abstract

The invention belongs to the field of drive axle assemblies of forklifts, and particularly relates to a drive axle of an electronic forklift. The drive axle of the electronic forklift comprises an axle housing assembly, a primary speed reducer arranged in the axle housing assembly, a secondary speed reducer arranged in the axle housing assembly, a hub and a brake, wherein the axle housing assembly comprises an axle housing and an axle cover; one end of the axle housing is opened and connected with the axle cover; a hub mounting hole position is arranged at the other end of the axle housing and used for mounting the hub; the primary speed reducer is driven by a cylindrical helical gear pair; the secondary speed reducer is driven by a cylindrical gear planetary system; and the brake is arranged on the outer side of the axle cover and is used for braking an axle shaft. The electronic forklift wheel edge drive axle power transmission direction is axially parallel to the hub (namely the wheel), the structure design is reasonable and compact, and the transmission efficiency is high.
