Description
Technical field
The present invention relates to car wheel electromotor technical fields, in particular to a kind of hub motor heat insulation loop and hub motor.
Background technique
It compared to the motor-driven electric vehicle of conventional central, is driven using outer rotor hub motor, to the dynamic flat of rotor
Weighing apparatus and heat-insulated there is very high requirement.
It is uneven to be typically due to wheel mass, balance weight can be installed on wheel and increase counterweight, make wheel in high speed rotation
When keep dynamic balancing.For outer rotor hub motor, since motor is located inside wheel rim, rotated by the rotor outside motor
Direct drive of wheel, therefore rotor is also required to keep dynamic balancing when rotated.And rotor is in the fabrication process, unavoidably
Ground will appear the phenomenon that non-uniform mass, so being also required to that certain measure is taken to increase counterweight.But usually motor supply
Quotient directly provides hub motor assembly, and the assembling of hub motor and the press fitting of wheel carry out respectively, and since hub motor seals
Requirement inconvenience disassembly, therefore rotor do not have done together with wheel dynamic balancing detection condition, need individually to motor
Rotor does dynamic balancing, if mass block is directly arranged on outer rotor, on the one hand will affect the magnetic field of outer rotor magnet steel.On the other hand
It is easy to appear and is not fixed firmly and falls off with the rotation of outer rotor.
Since outer rotor hub motor is directly driven by rotor, disc brake is usually fixed on rotor, disc brake is being made
Big calorimetric can be generated during dynamic, and general rotor is the preferable metal material of thermal conductivity, if excessive heat is transmitted to
On outer rotor, the permanent magnetism body heat being located on rotor demagnetization may be caused, this is breakneck.Heat conduction in order to prevent is drawn
The generation for sending out permanent magnetism body heat demagnetization problem, needs to install heat-proof device between rotor and disc brake.
Summary of the invention
Present invention aim to overcome above-mentioned the shortcomings of the prior art, providing one kind, that outer rotor can be improved is dynamic flat
The hub motor heat insulation loop and hub motor of weighing apparatus, good heat-insulation effect.
To achieve the above object, the present invention provides a kind of hub motor heat insulation loop, it is characterised in that: outside including fixed be located at
Heat insulation loop between rotor and disc brake is fixedly connected with balance weight in the heat insulation loop.
Annular groove is equipped on the inside of the heat insulation loop, the balance weight is by adhesive tape bonding in the annular groove.
The single balance weight includes multiple sequentially connected clump weights, and it is recessed to be equipped with counterweight between the adjacent clump weight
Slot.
The present invention also provides a kind of hub motors, including outer rotor and disc brake, it is characterised in that: further includes described above
Hub motor heat insulation loop, the axial direction in the heat insulation loop along the outer rotor is provided with fixation hole, the disc brake and it is described every
Hot ring is fixedly connected by threaded fastener with the outer rotor.
The beneficial effects of the present invention are: improving the dynamic flat of outer rotor simultaneously in the heat insulation for improving outer rotor and disc brake
Weighing apparatus property.Heat insulation loop is arranged in the present invention between outer rotor and disc brake, and is pasted with balance weight in the annular groove of heat insulation loop,
Fixation position and the quality that balance weight is determined according to the dynamic balancing testing result of hub motor improve the dynamic flat of outer rotor
Weighing apparatus property, while avoiding balance weight and being directly anchored to that the magnetic field of magnet steel is easy to fall off and influenced on outer rotor, heat insulation loop can be effective
Disc brake is obstructed because the heat outer rotor conduction that braking generates, guarantees the heat dissipation of outer rotor.
Detailed description of the invention
Fig. 1 is Structure explosion diagram of the invention.
Fig. 2 is balance block structure schematic diagram.
Fig. 3 is heat insulation loop structural schematic diagram.
Each part numbers are as follows in figure: outer rotor 2, disc brake 3, inner stator 4, heat insulation loop 6, balance weight 7, threaded fastener
8, fixation hole 9, annular groove 10, adhesive tape 11, clump weight 12, counterweight groove 13.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing, convenient for more clearly understanding the present invention, but they
Limiting the invention.
As shown in Figures 1 to 3, a kind of hub motor heat insulation loop, including it is fixed be located between outer rotor 2 and disc brake 3 every
Hot ring 6 is fixedly connected with balance weight 7 in heat insulation loop 6, annular groove 10 is equipped on the inside of heat insulation loop 6, and balance weight 7 passes through adhesive tape 11
It is bonded in annular groove 10, single balance weight 7 includes multiple sequentially connected clump weights 12, is equipped between adjacent clump weight 12
Counterweight groove 13.
The present invention also provides a kind of hub motor, including outer rotor 2 and disc brake 3, it is fixed at the axle center of outer rotor 2
Inner stator 4, further includes above-mentioned hub motor heat insulation loop, and the axial direction in heat insulation loop 6 along the outer rotor 2 is provided with fixation hole 9, is made
Dynamic dish 3 and heat insulation loop 6 are fixedly connected by threaded fastener 8 with outer rotor 2.
Heat insulation loop is first assembled between outer rotor and disc brake by hub motor of the present invention during fabrication, then into
Action balance detection is chosen in the annular groove for being mutually pasted onto heat insulation loop in requisition for the balance weight of weight mass according to testing result,
This ensure that balance of the outer rotor in operation process, while avoiding balance weight and being directly anchored to cause to be easy on outer rotor
Fall off and influence the magnetic field of outer rotor magnet steel；The material that heat insulation loop selects thermal conductivity poor can obstruct disc brake because of system
The raw heat outer rotor conduction of movable property, ensure that the thermal diffusivity of outer rotor, and counterweight groove is equipped between adjacent clump weight can be with
Certain radian is bent convenient for balance weight and is bonded completely with annular groove.
