Abstract
The utility model discloses a kind of hub motor shells, it includes a shell, and shell includes end cap and brake disc, end cap includes end face portion and radiating part, end face portion and the cooperation of brake disc veneer, are equipped with heat insulating coat, coating is attached in end face portion or brake disk surface between end face portion and brake disc.It is equipped with one layer of heat insulating coat between its end cap of the utility model and brake disc, effective barrier can be carried out to the heat generated in braking process.
Description
Technical field
The utility model relates to hub motor technical field, a kind of specifically hub motor shell.
Background technique
Instantly New-energy electric vehicle is entered Rapid development stage, and in the various driving sides of New-energy electric vehicle
In formula, hub motor is considered as the final driving method of electric car.Hub motor passes through integrated power device, transmission device
With brake apparatus in automotive hub, reduce the mechanical mechanism among motor to wheel, simplifies system composition, improve biography
Efficiency of movement reduces power battery consumption, increases and take space.But one for restrict hub motor development at present is important
Problem is hub motor overheat.The excessively high performance and safety that will affect motor of hub motor temperature, is mainly manifested in close to torque
Degree influences and magnet steel heat is caused to be demagnetized.
Summary of the invention
The technical problem to be solved by the utility model is to provide hub motor shells, set between end cap and brake disc
There is one layer of heat insulating coat, effective barrier can be carried out to the heat generated in braking process.
Technical solution adopted in the utility model is: it includes a shell, and the shell includes end cap and brake disc, institute
Stating end cap includes end face portion and radiating part, and the end face portion and brake disc veneer cooperate, set between the end face portion and brake disc
There is heat insulating coat, the coating is attached in end face portion or brake disk surface.
Preferably, the end face portion is radially distributed several protrusions, and end cap passes through protrusion and brake disc cooperation.
Preferably, described to project through bolt and brake disc secure fit.
Preferably, the protrusion and end face portion are integrally formed.
Preferably, the coating is ceramic coating or is coating made of anodic oxidation.
Preferably, the radiating part is equipped with radiating ribs.
The hub motor shell of the utility model, advantage are as follows: between the end cap face of hub motor shell and brake disc
Heat insulating coat, for surface attachment mode act on face, to replace conventional thermal barrier components, effectively barrier braking system
The heat generated during controlling is dynamic is conducted to motor side, to reduce motor entirety temperature rise, protects hub motor.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model hub motor shell.
Wherein, 1, shell, 2, end cap, 3, brake disc, 4, end face portion, 5, radiating part, 6, coating, 7, protrusion, 8, muscle.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the utility model provides hub motor shell, it includes a shell 1, and shell 1 includes end cap 2 and system
Moving plate 3, end cap 2 and brake disc 3 are coaxial design, and end cap 2 includes end face portion 4 and radiating part 5,3 veneer of end face portion 4 and brake disc
Cooperation is equipped with heat insulating coat 6 between end face portion 4 and brake disc 3.
Several protrusions 7 are distributed in embodiment one, end face portion 4 radially equidistantly, and end cap 2 passes through protrusion 7 and brake disc 3
Cooperation sets coating 6 in the mating surface, and coating 6 is attached on raised 7 faces, and protrusion 7 passes through 3 secure fit of bolt and brake disc,
The purpose designed in this way is that protrusion 7 cooperates with brake disc 3, and coating 6 need to be set to protrusion 7 and 3 binding face of brake disc
On, drag friction contact surface is utmostly reduced, while reducing 6 area of coating, also helps the handling and dimension of brake disc 3
Shield.Protrusion 7 and end face portion 4 are integrally formed, and guarantee raised 7 stability.
In addition, radiating part 5 is equipped with radiating ribs 8, radiating part 5 or is the conical surface, for area angle, the conical surface compares vertical plane
Greatly, i.e., radiating surface is bigger, is conducive to shell 1 and radiates；In addition, the conical surface not only reduces air drag, but also make brake disc 3 and end cap
The spacing in 2 faces increases, and is conducive to heat dissipation.
Coating 6 can be ceramic type coating, and ceramics not only have high temperature insulating effect, but also have wearability, very suitable
Together in heat-insulated under friction environment, done at anodic oxidation at the protrusion 7 directly on end cap 2 in addition, coating 6 can also be
Manage obtained coating, such as Al2O3Layer, to play high temperature insulating effect, while increasing the mechanical performance of mating surface.
Embodiment two, coating 6 are also attached on 3 end face of brake disc, i.e. brake disc 3 in addition to being attached in end face portion 4
On the end face directly contacted with end cap 2 or end face portion 4 and the equal adhering coating 6 in 3 end face of brake disc, remaining is the same as embodiment one.
The utility model preferred embodiment is described above, but is not to be construed as limiting the scope of the invention.
The utility model is not only limited to above embodiments, and specific structure is allowed to vary, all in the utility model demand for independence
Made various change is within the protection scope of the present utility model in protection scope.
