Description
Technical field
The utility model is related to a kind of wheel hub motor, more specifically, it relates to the wheel hub in a kind of novel hub motor
Casing.
Background technology
Wheel hub motor also known as wheel inner electric machine, exactly all integrate power, transmission and brake apparatus by its maximum feature
To in wheel hub, therefore the mechanical part of electric vehicle is greatly simplified.
Wheel hub motor includes hub shell and rear end cap, and hub shell with rear end cap is fixedly connected by fastener, institute
So that the increase of fit on operation, the time of cost increases, and ultimately results in the increase of cost.And, the bearing on rear end cap is straight
Connect and be embedded thereon, the wall thickness of rear section lid is relatively thin, there is no any safeguard measure, connection not enough firmly, has potential safety hazard.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of easy to assembly and bearing connection
Hub shell in firm novel hub motor.
To achieve the above object, the utility model provides following technical scheme：
A kind of hub shell in novel hub motor, including rear end cap, the hub shell are wholely set with rear end cap,
The inwall of the rear end cap forms pelvic cavity towards outer wall depression, and the inwall center of rear end cap is provided with round platform, in the round platform
Bearing for being connected with armature spindle is installed.
The utility model is further arranged to：The bearing includes inner ring and outer ring, and steel ball is provided between inner ring and outer ring
With two annular mountings, steel ball is placed between two mountings, filled with lubricating oil in the sealing space between two mountings.
The utility model is further arranged to：The cross section of the mounting is U-shaped.
The utility model is further arranged to：The hub shell includes for the coupling part for magnet steel absorption and is used for
The holder part of tire is connected, is wholely set by the straight-chromiun stainless steel coupling part being made and the holder part being made up of aluminium alloy.
The utility model is further arranged to：Plum blossom-shaped decoration line is provided with the outer wall of the rear end cap.
The utility model is further arranged to：The round platform is wholely set with rear end cap.
By using above-mentioned technical proposal, hub shell is with rear end cap by casting integrated shaping, it is not necessary to again by tight
Firmware is connected, easy to assembly, reduces installation time, reduces cost.On the one hand the setting of round platform is used to place bearing, fills bearing
With more firmly, on the other hand, strengthen the intensity of rear end cap, because bearing is used to be set in one end of armature spindle, bears stronger
Power, it is to avoid damage rear end cap, improves the service life of rear end cap.

Specific embodiment
The hub shell in a kind of novel hub motor of the utility model is described further with embodiment referring to the drawings.
According to Fig. 1, a kind of hub shell in novel hub motor, including rear end cap 2, the hub shell 1 with
Rear end cap 2 is wholely set, and the inwall of the rear end cap 2 forms pelvic cavity towards outer wall depression, and the inwall centre bit of rear end cap 2 is installed
Round platform 21 is equipped with, round platform 21 is wholely set with rear end cap 2, the bearing 3 for being connected with armature spindle is installed in the round platform 21.Wheel
Hub casing 1 is with rear end cap 2 by casting integrated shaping, it is not necessary to connected by fastener again, easy to assembly, when reducing assembling
Between, reduces cost.On the one hand the setting of round platform 21 is used to place bearing 3, bearing 3 is assembled more firmly, on the other hand, after enhancing
The intensity of end cap 2, because bearing 3 is used to be set in one end of armature spindle, bears stronger power, it is to avoid damages rear end cap 2, carries
The service life of rear end cap high 2.
Shown in hookup 1, hub shell 1 is included for the coupling part 11 for magnet steel absorption and the branch for connecting tire
Frame part 12, is wholely set by the straight-chromiun stainless steel coupling part 11 being made and the holder part 12 being made up of aluminium alloy.Aluminium alloy
The heat dispersion of holder part 12 being made preferably, reduces the demagnetization rate of motor, improves the service life of motor.
According to Fig. 2, plum blossom-shaped decoration line 22 is provided with the outer wall of rear end cap 2.Decoration line 22 is formed after being recessed, and is risen
To the effect of decoration.
Bearing 3 includes inner ring and outer ring, and steel ball and two annular mountings 31 are provided between inner ring and outer ring, and steel ball is placed in two envelopes
Between piece 31, lubricating oil is filled with the sealing space between two mountings 31.The cross section of mounting 31 is U-shaped（As shown in Figure 3）.
The effect of mounting 31 is lubrication of the influence lubricating oil to steel ball in order to the lubricating oil in exclusion seal space departs to outside bearing 3
Effect, the mounting 31 of U-shape structure can increase the lubricating oil amount of storage in closing space, when the lubricant effect to steel ball continues
Between it is longer.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.Should refer to
