Abstract
The utility model relates to a novel hub structure of a driving motor, which is formed by a driving motor and a hub which is coaxially and fixedly arranged on the driving motor along a radial direction, wherein spoke holes are uniformly distributed on the hub, and the spoke holes are radial spoke holes. The utility model has simple integral structure, ingenious design, can perfectly solve the problem that troubles the electric motor car industry for a long time only by changing the spoke holes from an axial direction to a radial direction, thereby ensuring the safety and the reliability when an electric motor car is ridden, decreasing the maintenance number and the maintenance cost of the electric motor car, and causing the development of the electric motor car industry to be greatly progressed.
Description
Technical field
The utility model belongs to electric automobiles, particularly a kind of novel colored hub structure of drive motor.
Background technology
Battery-driven car mainly is made up of car body, drive motor, battery, controller, and motor coaxle radially is installed in the colored hub of wheel, drives wheel thereby the flower hub adopts the spoke of uniform arrangement to be connected with rim.The made spoke hole of existing battery-driven car flower hub is homoaxial with wheel always, and correspondingly, the end of spoke also will be made a bending that matches with this spoke hole to realize the installation of the spoke other end and rim.Because it is bigger that battery-driven car and bicycle are compared overall weight, and the wheel diameter of battery-driven car is little, but the axletree than bicycle is a lot of greatly for the diameter of motor flower hub, therefore the spoke of battery-driven car is shorter, thereby causes the ability that bears of spoke relatively poor, especially takes place under the situation of vibration at battery-driven car in the process of riding, the phenomenon that spoke fractures very easily appears, not only reduce the service life of spoke, increased the frequency of maintenance and the maintenance cost of battery-driven car, also reduced the safe reliability of riding.
Increasing the spoke pulling force can take following two kinds of methods to realize: 1. increase spoke diameter method, but adopt this method need guarantee that the diameter of bending part is more than three times of spoke diameter, so technology is difficult to realize; 2. spoke intersects the installation method, because the distance between adjacent two spoke holes is less on the flower hub, this method is difficult to realize equally.Spoke fractures when therefore how to avoid the battery-driven car vibration, improves the safety of riding and has become a difficult problem of demanding urgently overcoming in the evolution of spoke type battery-driven car.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, make easily, can effectively avoid spoke to fracture, improve the novel colored hub structure of the drive motor of riding safety.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of novel colored hub structure of drive motor constitutes by drive motor and at the drive motor coaxial colored hub that installs that directly makes progress, and the uniform spoke hole that is shaped on the flower hub is characterized in that: on colored hub the uniform spoke hole that is shaped on be the radial spoke cylindrical void.
And uniform made spoke hole is two rows on the described colored hub, and this two rows spoke hole is for being symmetrical arranged, perhaps for shifting to install.
And uniform made spoke hole is coaxial two rows with the footpath on the described colored hub.
Advantage of the present utility model and beneficial effect are:
1. this novel colored hub structure is to be shaped on uniform radial spoke cylindrical void on the flower hub, because made spoke hole is a radial distribution, the spoke that is inserted in the spoke hole is straight-bar structure rather than bending structure, solved the problem of spoke bending part frangibility, thereby guaranteed the safe reliability when battery-driven car is ridden, eliminate potential safety hazard, solved a difficult problem in the battery-driven car manufacturing process.
2. this novel colored hub structure makes the spoke that is inserted in the novel colored hub motor spoke hole needn't make the bending structure, simplifies the manufacturing process of spoke, and it is easily simple more that it is made.
3. the utility model integral structure is simple, design ingenious, only need its spoke hole can perfectly be solved puzzlement battery-driven car industry problem for a long time by axially changing into radially, guaranteed the safe reliability when battery-driven car is ridden, reduced battery-driven car frequency of maintenance and service expenditure, made the development of battery-driven car industry obtain a qualitative leap.

Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the birds-eye view of another embodiment of the utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Embodiment 1:
A kind of novel colored hub structure of drive motor constitutes by drive motor 1 and at the drive motor coaxial colored hub 2 that installs that directly makes progress, the uniform spoke hole 3 that is shaped on the flower hub, and general, uniform made spoke hole is coaxial with two rows directly on the flower hub.Innovative point of the present utility model is: the uniform spoke hole that is shaped on of institute is the radial spoke cylindrical void on the flower hub, and the quantity of spoke hole can be set according to the specification of battery-driven car, and flower uniform made two is arranged spoke holes for being symmetrical arranged on the hub in the present embodiment.
Because spoke hole and drive motor axle are for radially being provided with, therefore the spoke that is inserted in the spoke hole can manufacture the straight-bar structure and needn't make the bending structure, the perfect thus problem that has solved spoke bending part frangibility when battery-driven car jolts.
Embodiment 2:
Just uniform two made row's spoke holes are for shifting to install on the flower hub, and other are same as embodiment 1.
The drive motor of the novel colored hub of this battery-driven car both can be installed in the front vehicle wheel of battery-driven car, also can be installed in the rear wheel of battery-driven car.
Claims (3)
1. the novel colored hub structure of a drive motor constitutes by drive motor and at the drive motor coaxial colored hub that installs that directly makes progress, and the uniform spoke hole that is shaped on the flower hub is characterized in that: on colored hub the uniform spoke hole that is shaped on be the radial spoke cylindrical void.
2. the novel colored hub structure of drive motor according to claim 1, it is characterized in that: uniform made spoke hole is two rows on the described colored hub, this two rows spoke hole is for being symmetrical arranged, perhaps for shifting to install.
3. the novel colored hub structure of drive motor according to claim 2 is characterized in that: uniform made spoke hole is coaxial two rows with the footpath on the described colored hub.
