3 ' are fixed on motor body 2 ', then the play of motor shaft 1 ' will cause brake caliper 4 ' assembly it is not in place, influence itself and dish
The axially mounted positioning of brake disk 3 ' influences braking effect to the problem of rubbing partially or drag brake occur.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of positioning knot of hub for electric vehicle formula motor
Structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of location structure of hub for electric vehicle formula motor, including motor shaft and hub-type motor body, the motor
Ontology passes through the bearing being arranged inside and is rotationally connected on motor shaft, and disk brake passes through motor shaft and is fixedly mounted on motor body
Mounting base on, the both ends of motor shaft are fixedly mounted on reel cage, brake caliper is installed on reel cage with clamp disk brake realization
Braking is set with positioning shaft sleeve between the mounting base and reel cage on the motor shaft, described positioning shaft sleeve one end against
Bearing inner race in mounting base is simultaneously set with oil sealing and is covered, and the other end is locked reel cage and positioning shaft sleeve by locking member
It is fixed, while reel cage is located on motor body by the end face of positioning shaft sleeve.
The reel cage is equipped with butting section, and the positioning shaft sleeve abuts against in portion.
The butting section is formed by the spacer pad being mounted on reel cage.
The positioning shaft sleeve is set there are two hole for injecting glue, and described two hole for injecting glue are arranged oppositely, and the motor shaft corresponds to injecting glue
Hole, which is equipped with, holds glue groove A.
Motor shaft where the positioning shaft sleeve end, which is equipped with, holds glue groove B.
The positioning shaft sleeve is equipped with convex edge against one end of the bearing inner race.
The beneficial effects of the utility model are: empty place of the utility model only between former mounting base and reel cage is provided with
Positioning shaft sleeve makes the axially position of brake caliper be no longer rely on motor shaft itself, but by the bearing in motor body and determines
Position axle sleeve, then the axially position of brake caliper and disk brake is influenced small by installation error and axial float, and positioning accuracy is more held
Easily guarantee, thus effectively solve the problems, such as to rub partially, drag brake, meanwhile, structure is simple, easy for installation.

Specific embodiment
A kind of location structure of hub for electric vehicle formula motor referring to Figure 2 to Figure 4, including motor shaft 1 and hub-type electricity
Machine ontology 2, motor body 2 pass through the bearing 7 being arranged inside and are rotationally connected on motor shaft 1, and disk brake 3 passes through motor shaft 1 simultaneously
It is fixedly mounted in the mounting base 21 of motor body 2, as motor body 2 rotates together, the both ends of motor shaft 1 are fixedly mounted on
Brake caliper 4 is installed to clamp the braking that disk brake 3 realizes hub-type motor body 2 on reel cage 5, on reel cage 5.With the prior art
The positioning that middle brake caliper only leans on motor shaft to realize is different, be set on motor shaft 1 setting of locating shaft sleeve 6 mounting base 21 with
Empty place between reel cage 5,7 inner ring of bearing that 6 one end of positioning shaft sleeve is resisted against in mounting base 21 are simultaneously set with oil sealing 8 and are sealed
Lid, the other end is locked by locking member 9 with reel cage 5, at this point, the axially position of brake caliper is no longer rely on motor shaft sheet
Body, but rely on motor body 2 and positioning shaft sleeve 6, then the axially position of brake caliper 4 and disk brake 3 is by installation error and axis
Influence to play is small, and positioning accuracy is easier to ensure that, to effectively solve the problems, such as to rub partially, drag brake；It is fixed to be realized with positioning shaft sleeve 6
Not only structure will not be excessively complicated for position, and is quickly and expediently installed, and does not influence assembly efficiency.
As a preferred embodiment of the present invention, reel cage 5 is equipped with butting section 51, and the end face of butting section 51 is smooth, when fixed
When position axle sleeve 6 is abutted against in portion 51, reel cage 5 can ensure good location and installation by butting section 51.Further, against
Portion 51 is formed by the spacer pad 10 being mounted on reel cage 5, and generation type is simple and convenient.
Preferably, positioning shaft sleeve 6 is equipped with hole for injecting glue 61, the corresponding hole for injecting glue 61 of motor shaft 1, which is equipped with, holds glue groove A11,
After positioning shaft sleeve 6 and motor body 2 and reel cage 5 install, begins through hole for injecting glue 61 and gluing and pass through in positioning shaft sleeve 6
Appearance glue groove A11 on motor shaft accommodates silica gel to realize sealing waterproof, prevents between the located axle sleeve 6 of water and motor shaft
Gap flows into motor body 2；And hole for injecting glue 61 is two be arranged oppositely, then after silica gel fills, silica gel can be from the other end
Hole for injecting glue 61 flow out to show that injecting glue has been filled with completion.
Further, in order to make between positioning shaft sleeve 6 and motor shaft 1 realize better seal waterproof, 6 end of positioning shaft sleeve
The motor shaft 1 at place, which is equipped with, holds glue groove B12, and after positioning shaft sleeve 6 installs, first toward holding, glue groove B12 is interior to inject silica gel
Reel cage 5 is installed again, is tightly connected positioning shaft sleeve 6 with reel cage 5, holding glue groove B12 at this time is that first layer seals waterproof, with appearance glue
Groove A11 constitutes double-layer seal waterproof construction.
Preferably, positioning shaft sleeve 6 is convexly equipped with convex edge 62 against one end of 7 inner ring of bearing, in increase and bearing 7
