Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 8, a dual-function electric driving apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

This dual function's electric drive device includes steering column 1, steering column 2, rotation axle sleeve 5, preceding arm roof beam 6, single arm roof beam 7, single axle wheel hub motor 8, there is mounting flange 4 through the bolt fastening on the steering column 2, and mounting flange 4 keeps away from steering column 2 end and passes through lock nut 3 fixedly rotate axle sleeve 5, preceding arm roof beam 6 is fixed through bolted connection with rotation axle sleeve 5, it is fixed that single arm roof beam 7 passes through bolted connection with preceding arm roof beam 6, single axle wheel hub motor 8 is installed and is fixed on single arm roof beam 6, conversion flange 9 installation is fixed on single axle wheel hub motor 8, steering column 1 passes rotation axle sleeve 5 and carries out fixed mounting with preceding arm roof beam 6 or conversion flange 9.

Specifically, bearings 10 are arranged at the upper end and the lower end of an inner hole of the fixed flange 4; needle roller bearings 11 are arranged at the upper end and the lower end of an inner hole of the rotating shaft sleeve 5; the surface of the rotating shaft sleeve 5 is provided with a limiting chute 12; the front arm beam 6 is provided with a fixed anti-drop hole 13; the mounting end surfaces of the single-arm beam upper 7 and the front arm beam 6 are assembled in a matching way through trapezoidal teeth; the assembly form of the steering column 1 and the front arm beam 6 is the same as the assembly form of the steering column 1 and the conversion flange 9, and the assembly structures are spline assembly, D-axis assembly, key groove assembly and the like.

Example 1

When the drifting kart is used, referring to fig. 7, the steering support column 2 is welded on the frame 12, the steering wheel is arranged on the steering column 1, two universal wheels 14 are arranged on the frame 12, and the upper seat 13 is arranged, which is an application case of the drifting kart

When the single-output-shaft hub motor 8 is used as a drifting kart, the single-output-shaft hub motor is a driving wheel and a steering wheel, and two universal wheels are arranged behind the single-output-shaft hub motor, so that drifting can be better performed; when the steering wheel rotates, the limiting groove is formed in the rotating shaft sleeve 5, and the steering angle can be limited.

Example 2
