Description
Technical field
The present invention relates to electric automobiles, more particularly, to a kind of side hanging electric bicycle bi-motor housing.
Background technology
Electric car is due to low-carbon, energy saving, use cost is light, deep to be liked by consumer.The current electric car owning amount in China is big
In 200,000,000, by the technological progress of more than ten years, battery-operated motor cycle, Development of Electric Vehicles progressively rise, and market is not therewith
Disconnected to expand, relevant battery-operated motor cycle standard, electric automobile standard are expected to put into effect quickly, and the requirement of user also constantly rises
Level, such as electric automobile requirement speed reaches the racing car of 75 horses and electric motorcycle and the quality of freight truck is not known
Property, known wheel hub electric motor of electric vehicle, differential speed motor technology, speed and moment of torsion are immutable, can not be satisfied with following electric vehicle
Particular/special requirement, the prior art needed for such as climbing load in the case of large torque, often shows in special operational process
It is bad even to shut down, especially loaded under conditions of vehicle needs premised on speed unable to do what one wishes, unique solution is
Amplifying power.
To solve the performance strength of vehicle bigger in operation, Dual-motors Driving pattern has been begun attempt in field, such as
Say wheel hub motor, when single motor undercapacity, start auxiliary-motor work, but this designing scheme is the list for sacrificing normal operation
Electric efficiency is preceding topic.
The content of the invention
The present invention is solution defect existing in the prior art, there is provided a kind of motor integrating shell of main motor and auxiliary-motor
Body, can make housing periphery set radiating ribs, increase heat dissipation area, two outside the installation of the main motor and auxiliary-motor of motor casing
In the perisporium of side and lower section, set several straight wall through holes directly to receive air-cooled, dissipated faster so that main motor, auxiliary-motor possess
Hot function, lifting electric efficiency obtain increase and continue ability.
A kind of side hanging electric bicycle bi-motor housing of the present invention, it is characterised in that it is equal that motor casing periphery faces radiating ribs directly
Cloth；Two side of motor casing is formed with the iron core installation die cavity of main motor and auxiliary-motor, and the decile being connected with babinet is formed with outside die cavity
Perforation；Semicircle straight trough is formed with the internal diameter perisporium of die cavity, semicircle straight trough can be used for the positioning of electric machine iron core installation；In master
Motor cavity is connected with straight wall with auxiliary-motor chamber adjacent part and is controlled with babinet close fit, composition controller junction chamber and installation
Device.
In a kind of form, in the perisporium of two sides and lower section outside the installation of the main motor and auxiliary-motor of motor casing, set
Several straight wall through holes, setting the benefit of straight wall through hole, that the stator of motor can be allowed directly to receive is air-cooled, reduces motor temperature rise, carries
High electric efficiency, increase the ability that continues.
Further, set straight wall through hole to save raw material, mitigate production cost.
Further, motor casing and babinet and main motor junction chamber, auxiliary-motor junction chamber close fit.
A kind of side hanging electric bicycle bi-motor housing of the present invention, employs the integral housing system of main motor and auxiliary-motor
Make, can make housing periphery that radiating ribs are set, increase heat dissipation area, two outside the installation of the main motor and auxiliary-motor of motor casing
In the perisporium of side and lower section, several straight wall through holes are set, set straight wall through hole benefit that the stator of motor can be allowed directly to receive
Air-cooled, so that main motor, auxiliary-motor possess faster heat sinking function, lifting electric efficiency obtains increase and continues ability, a body shell
System makees that motor casing acquisition can be allowed once molding formed, saves molding expenses of labour, while in main motor and auxiliary-motor adjacent space
Controller assembly section is set, makes controller installation more reasonable, have rejected the cumbersome mode of connection of known technology.
Brief description of the drawings
Fig. 1 is top view of the present invention；
Fig. 2 is front view of the present invention；
Fig. 3 is the cooperation schematic diagram of babinet.
Embodiment
The invention discloses a kind of side hanging electric bicycle bi-motor housing, as shown in Figure 1, 2, 3, it is characterised in that electricity
It is uniformly distributed that casing periphery faces radiating ribs 4 directly；Two side of motor casing is formed with the iron core installation die cavity of main motor 1 and auxiliary-motor 2, outside die cavity
Portion is formed with the decile perforation 5 being connected with babinet；Semicircle straight trough A is formed with the internal diameter perisporium B of die cavity, semicircle straight trough A can
Positioning for electric machine iron core installation；It is connected in 1 chamber of main motor with 2 chamber adjacent part straight wall 6 of auxiliary-motor and straight with babinet
61 close fit of wall block reinforcement, forms controller junction chamber 3 and installation controller.
In a kind of form, in the perisporium of two sides and lower section outside the installation of the main motor 1 and auxiliary-motor 2 of motor casing, if
Put several straight walls through hole C, setting the benefit of straight wall through hole C, that the stator of motor can be allowed directly to receive is air-cooled, reduces motor temperature
Rise, improve electric efficiency, increase the ability that continues.
Further, set straight wall through hole C to save raw material, mitigate production cost.
Further, the main motor junction chamber 11 of motor casing and babinet, 21 close fit of auxiliary-motor junction chamber.
Further, the decile perforation 5 and the 51 correct centering of mounting hole of babinet of motor casing babinet connection.
Further, 31 close fit of controller fitting area of controller junction chamber 3 and babinet, it is ensured that sealing state, in order to avoid
Rainwater enters.
A kind of side hanging electric bicycle bi-motor housing of the present invention, employs the integral housing of main motor 1 and auxiliary-motor 2
Make, can make housing periphery that radiating ribs 4 are set, increase heat dissipation area, in the installation of the main motor 1 and auxiliary-motor 2 of motor casing
In the perisporium of exterior two sides and lower section, several straight walls through hole C is set, sets straight wall through hole C benefits to allow the stator of motor
Directly receive air-cooled, so that main motor 1, auxiliary-motor 2 possess faster heat sinking function, lifting electric efficiency obtains increase and continues energy
Power, integral housing, which makes, can allow motor casing acquisition once molding formed, save molding expenses of labour, while in main motor 1 and pair electricity
2 adjacent space of machine sets controller assembly section, makes controller installation more reasonable, have rejected the cumbersome wiring side of known technology
Formula.
