The utility model provides a kind of wheel hub motor fixing device for installing, including：Mounting bracket, motor shaft and key block； The motor shaft is provided with stopper slot；The key block is tabular, and the key block and the motor shaft contact surface are the first face, described The area in the first face is more than the sectional area of the stopper slot；The cavity of irregular shape is provided with inside the mounting bracket, it is described The shape of cavity is consistent with the integral outer profile that the key block and the motor shaft combine.Motor shaft and peace in the utility model Dress support is fixedly connected by key block, and the contact area of key block and motor shaft is larger, avoids the radial displacement of motor shaft, simultaneously The area of the contact surface of key block and motor shaft is more than the area of motor shaft stopper slot, is advantageous to transmission of the key block to motor shaft, reaches To more preferable fixed effect, when solving the mobile chassis when the electrodynamic balance car using single shaft or robot, traditional peace Assembling structure can not provide the technical problem of good installation fixed effect.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of installation diagram of the wheel hub motor fixing device for installing provided in the utility model embodiment；
Fig. 2 is a kind of explosive view of the wheel hub motor fixing device for installing provided in the utility model embodiment；
Reference is as follows：
1st, motor shaft；2nd, mounting bracket；3rd, key block；4th, bolt；5th, motor shaft insert port；6th, key block insert port；7th, it is spacing Groove.
Embodiment
The utility model embodiment discloses a kind of wheel hub motor fixing device for installing, and motor shaft and mounting bracket pass through key Block is fixedly connected, and the contact area of key block and motor shaft is larger, avoids the radial displacement of motor shaft, while key block and motor shaft Contact surface area be more than motor shaft stopper slot area, be advantageous to transmission of the key block to motor shaft, reach more preferable fixation Effect, when solving the mobile chassis when the electrodynamic balance car using single shaft or robot, traditional mounting structure can not The technical problem of good installation fixed effect is provided.
Fig. 1 and Fig. 2 are referred to, one of a kind of wheel hub motor fixing device for installing provided in the utility model embodiment Embodiment, including：Mounting bracket 2, motor shaft 1 and key block 3；
Motor shaft 1 is provided with stopper slot 7；
Key block 3 is tabular, and key block 3 is the first face with the contact surface of motor shaft 1, and the area in the first face is more than cutting for stopper slot 7 Area；
It is provided with the cavity of irregular shape inside mounting bracket 2, the shape of cavity is combined whole with key block 3 and motor shaft 1 External contouring is consistent.
