Summary of the invention
In order to overcome, the structural strength of vehicle frame in existing electri forklift driving wheel structure is poor, manufacture difficulty is high and the deficiency of waste material, the utility model provide a kind of structural strength of vehicle frame good, be convenient to the electri forklift forerunner mechanism that manufactures.
The technical scheme in the invention for solving the technical problem is: a kind of electri forklift forerunner mechanism, comprise a wheel carrier, and on described wheel carrier, be connected with a drive motor, the output shaft of described drive motor is provided with input gear; Also comprise the big gear wheel and the miniature gears that are located on same gear wheel shaft, described gear wheel shaft is rotatable to be located on described wheel carrier; The described big gear wheel input gear that is connected with a joggle; Also comprise that one is enclosed within the drive wheel that the outer drive motor relatively of drive motor rolls, and is provided with bearing between described drive wheel and drive motor; Described drive wheel is provided with internally toothed annulus, and described internally toothed annulus and miniature gears are connected with a joggle.
For preventing that lubricating grease from flowing out, described drive wheel internally toothed annulus front end is provided with bound edge, between described bound edge and wheel carrier, is provided with sealing lip.
When drive motor is earlier and miniature gears is interfered, on the shell of described drive motor, corresponding miniature gears is provided with a miniature gears groove, and described pinion part is divided in miniature gears groove.
A design for drive motor shell, the later half shell that the first half shell that the shell of described drive motor consists of No. 35 steel and No. 20 steel form is welded.The mode of described welding can adopt built-up welding, between first half shell and later half shell, arranges in built-up welding triangle and introduces welding fluid.The first half shell intensity ratio of No. 35 steel is better, is applicable to pressure-bearing and links together with wheel carrier, and the magnet conductivity of No. 20 steel is relatively good, and motor efficiency when cutting magnetic induction line does work can obtain raising to a certain extent.
For ease of setting up of bearing, also pre-small post-largely on described later half shell be provided with a step, in described bearing, by latter one, withstand on described step.
The utility model is consistent with the drive wheel mechanism of prior art in use, does not repeat them here.
The beneficial effects of the utility model are: 1: adopt the internally toothed annulus of being located on drive wheel to replace the sun gear in contrast patent, its miniature gears is positioned at internally toothed annulus, the position of gear wheel shaft is low, big gear wheel on gear wheel shaft is just lower, the cavity that holds big gear wheel digging on wheel carrier is superficial, is convenient to wheel carrier manufacture and improves wheel carrier intensity.2: the first half shell of drive motor shell adopts No. 35 steel makings, and intensity ratio is better, and later half shell is by No. 20 steel makings, and magnet conductivity is good, electrical efficiency improves.
