In sub-set, there is no spline structures, can not play the role of the transmission and axial movement of radial power, greatly limit electronic
The transmission effect of vehicle axis, so that s function is more traditional single in traditional electric vehicle.
Utility model content
The main purpose of the utility model is to provide a kind of electric vehicle middle axle devices, can effectively solve in background technique
The problem of.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of electric vehicle middle axle device, including axis, surface one end of the axis are fixedly connected with sprocket wheel, the sprocket wheel
One end be fixedly connected with spline chieftain set, the surface of the sprocket wheel is provided with latch slot, the surface one of the spline chieftain set
Side is fixedly connected with bolt by gasket and stop nut, and the surface other side of the spline chieftain set is provided with spline tooth.
Further, the both ends of the cylindrical structure of the axis, the axis are fixedly connected with biography by connecting crank
Moving gear.
Further, the center point of axis, the table of the sprocket wheel is arranged in sprocket wheel structure in the form of annular discs, the sprocket wheel
The setting of face side is fluted.
Further, the surrounded surface for being distributed in sprocket wheel in a ring of the latch slot, distance phase between the latch slot
Together.
Further, the bolt is closely connect with spline chieftain set, the cylindrical structure of bolt.
Further, a side surface of the spline tooth protrusion spline chieftain set, the surface surrounding setting of the spline tooth
There is burr.
Compared with prior art, the utility model has the following beneficial effects: this kind of utility model design is reasonable, user
Just, by being provided with spline chieftain set and spline tooth, spline chieftain is conveniently fixed on by spline tooth and is put on, convenient for passing through spline
Tooth plays the role of the transmission and axial movement of radial power, transmits power convenient for axis, by be provided with bolt, gasket and
Stop nut, it is convenient that spline chieftain set is fixed by bolt, it prevents during middle axle driven, spline chieftain set is de-
It falls, the utility model is simple and convenient, is suitble to be widely popularized.
