Abstract
The invention provides an installation structure for an electric-steering forward steering wheel, which can solve the problem that the current structure is difficult to assemble, and greatly improve the assembling efficiency. The installation structure comprises a steering wheel assembly, a step motor and a hood, wherein the step motor is arranged inside the hood, and is connected with a car frame by a step motor rack; the hood is arranged on the car frame; the steering wheel assembly is arranged in a hood hole; and the steering wheel assembly comprises a steering wheel upper cover and a steering wheel shaft disc which are connected through a bolt, wherein the steering wheel shaft disc is connected with the motor shaft hole of the step motor in a matched manner, and is fixed by a fastening bolt. The installation structure is characterized in that a threaded through hole is formed in the steering wheel upper cover, the steering wheel shaft disc is provided with a threaded installation hole, and the steering wheel upper cover and the steering wheel shaft disc are connected through the bolt from top to bottom through the threaded through hole and the threaded installation hole.
Description
Technical field
The present invention relates to vehicle for cargo handling and make the field, be specially electricity and turn to shift-forward type bearing circle mounting structure.
Background technology
Existing electricity turns to shift-forward type bearing circle mounting structure to see Fig. 1, it comprises steering wheel assembly, stepping motor 5, wherein steering wheel assembly comprises by the first bolt 3 from bottom to top bearing circle loam cake 1 and the bearing circle reel 2 of assembly connection, first stepping motor 5 is installed on the stepping motor frame 6 during assembling, stepping motor frame 6 is connected with vehicle frame, again hood 7 is fixed on the vehicle frame, the steering wheel assembly that will assemble at last inserts in the hood aperture, and the axis hole on the bearing circle reel and step motor shaft carried out axis hole coupling and fastening by the second bolt 4, the shortcoming of this mounting structure is: it installs first hood 7, the travel direction disc assembly is connected with the axis hole of stepping motor again, and hood can hide the installation site of axis hole assembling, the assembling difficulty that causes steering wheel assembly and the stepping motor particularly motor shaft of bearing circle reel and stepping motor carries out can't carrying out after the axis hole assembling the fastening installation of the second bolt 4, and efficiency of assembling is low.
Summary of the invention
For the problems referred to above, the invention provides electricity and turn to shift-forward type bearing circle mounting structure, it can solve the assembling hard problem that existing structure exists, and greatly improves efficiency of assembling.
Its technical scheme is such, it comprises steering wheel assembly, stepping motor and hood, described stepping motor is installed in the described hood, and be connected with vehicle frame by the stepping motor frame, described hood is installed on described vehicle frame, described steering wheel assembly is installed on hood aperture, described steering wheel assembly comprises by bolted bearing circle loam cake and bearing circle reel, described bearing circle reel is connected with the motor shaft shaft hole matching of described stepping motor, and fix by binding bolt, it is characterized in that: described bearing circle loam cake has tapped through hole, described bearing circle reel has threaded mounting hole, and described bolt is connected and fixed described bearing circle loam cake and described bearing circle reel from top to bottom by described tapped through hole and threaded mounting hole.
Adopt bearing circle mounting structure of the present invention, its beneficial effect is: bearing circle loam cake and the bearing circle reel of its steering wheel assembly are connected and fixed from top to bottom by bolt, thereby when whole bearing circle is installed, can at first be fixed on stepping motor on the stepping motor erecting frame, again bearing circle reel and the motor shaft of stepping motor are carried out using binding bolt fastening after axis hole is connected, then hood is installed on vehicle frame, at last the bearing circle loam cake is buckled on the bearing circle reel and is joined with bolts and get final product, it has reduced the installation difficulty of bearing circle, thereby can greatly improve installation effectiveness.
