Technical field
The utility model relates to a kind of electric wheel hub device for quickly disassembling.
Background technology
What the electric wheel hub on the Electrical Bicycle mainly adopted is external rotor electric machine, and the internal stator in this motor is fixed on the electric machine main shaft, and not rotatable, outer rotor then is fixedly linked through speed reduction gearing and sun wheel, and can rotate around electric machine main shaft; When outer rotor when electric machine main shaft rotates, sun wheel is just and then rotation also, and then rotates by the hub shell that satellite gear drives the outside.At present, this electric wheel hub the fixed form on the Electrical Bicycle mainly be two end axles with electric machine main shaft to rivetting on the vehicle frame of both sides, between electric machine main shaft and vehicle frame, install the spline sheet again additional.Though it is firm that this fixed form can guarantee that electric wheel hub is connected with the both sides vehicle frame, in case electric wheel hub break down and need repairing or when changing, to the dismounting of electric wheel hub and installation subsequently not only time-consuming but also effort all, comparatively inconvenient.
Summary of the invention
The utility model purpose is: a kind of electric wheel hub device for quickly disassembling is provided, can be with firm being connected on the vehicle frame of electric wheel hub, and assembly and disassembly are all flexible.
The technical solution of the utility model is: a kind of electric wheel hub device for quickly disassembling comprises the electric wheel hub that is positioned between the vehicle frame of both sides and is located at electric machine main shaft on the electric wheel hub that it comprises that also a pull bar, pulls handle, a bearing pin, an adjustment nut and a location briquetting; Describedly pull the operate portions that the handle top is a curved arc shape, operate portions is provided with eccentric orfice, and bearing pin places in this eccentric orfice; Described pull bar is located in the electric machine main shaft, and the one end passes the solid adjustment nut of a sidecar frame spiral shell, and the other end passes the sheathed location of opposite side vehicle frame briquetting, and radially fixes aforementioned bearing pin.
The technical scheme that the utility model is more detailed is: a kind of electric wheel hub device for quickly disassembling, comprise the electric wheel hub that is positioned between the vehicle frame of both sides and be located at electric machine main shaft on the electric wheel hub that it comprises that also a pull bar, pulls handle, a bearing pin, an adjustment nut and a location briquetting; Describedly pull the operate portions that the handle top is a curved arc shape, operate portions is provided with eccentric orfice, and bearing pin places in this eccentric orfice; Described pull bar is located in the electric machine main shaft, and the one end passes the solid adjustment nut of a sidecar frame spiral shell, and the other end passes the sheathed location of opposite side vehicle frame briquetting, and radially fixes aforementioned bearing pin.Have cone-shaped spring between one side end face of described adjustment nut and electric machine main shaft, and also have cone-shaped spring between the opposite side end face of location briquetting and electric machine main shaft; Adding the cone-shaped spring purpose is for pull bar provides axial tensile force, and preventing to pull handle, to depress the back loosening, thus guarantee between electric wheel hub and the both sides vehicle frame be connected further firm, reliably.With adding the spline sheet between the vehicle frame of both sides, the spline sheet is a prior art respectively at the two ends of described electric machine main shaft, and purpose is to prevent that electric machine main shaft from can not rotate.And described bearing pin is provided with screw radially, and bearing pin is solid on pull bar by this screw spiral shell.
The utility model advantage is:
1. the utility model electric wheel hub device for quickly disassembling is simple in structure, and is easy to assembly, only need depress during use and pull handle, just can be with firm being locked between two vehicle frames of electric wheel hub; And when dismounting only needs a pull-up pull handle, unclamps adjustment nut again and extract pull bar out electric wheel hub is taken off, and dismantles also very flexible.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is for pulling the structural representation of handle pull-up state among Fig. 1 embodiment;
Wherein: 1, electric wheel hub; 2, a sidecar frame; 3, opposite side vehicle frame; 4, electric machine main shaft; 5, pull bar; 6, pull handle; 60, operate portions; 7, bearing pin; 8, adjustment nut; 9, location briquetting; 10, cone-shaped spring; 11, spline sheet.
The specific embodiment
Embodiment: in conjunction with Fig. 1, Figure 2 shows that a kind of specific embodiment of the utility model electric wheel hub device for quickly disassembling, it comprises the electric wheel hub 1 that is positioned at 2,3 of both sides vehicle frames and is located at electric machine main shaft 4 on the electric wheel hub 1, and it comprises that also a pull bar 5, pulls handle 6, a bearing pin 7, an adjustment nut 8 and a location briquetting 9; Describedly pull the operate portions 60 that handle 6 tops are curved arc shape, operate portions 60 is provided with eccentric orfice, and bearing pin 7 places in this eccentric orfice; Described pull bar 5 is located in the electric machine main shaft 4, and the one end passes the solid adjustment nut 8 of a sidecar frame 2 spiral shells, and the other end passes opposite side vehicle frame 3 sheathed location briquettings 9, and radially fixes aforementioned bearing pin 7.
Have cone-shaped spring 10 between one side end face of adjustment nut described in the present embodiment 8 and electric machine main shaft 4, and also have cone-shaped spring 10 between the opposite side end face of location briquetting 9 and electric machine main shaft 4.
