Description
Technical field
The present invention relates to electric vehicle motor technical fields, the in particular to automobile-used lightweight wheel hub of two-wheel electric.
Background technique
Electric vehicle meets vast city as the new energy vehicles with various features such as its economic, environmentally protective, fashion
One people's livelihood walking-replacing tool of the people.With electric bicycle new national standard GB17761-2018 " electric bicycle technical specification of security "
Publication, and full text clause is pressure standard.Wherein key plank requires complete vehicle weight particularly important no more than 55KG, therefore
The light-weight design of vehicle requires extremely urgent.
But the wheel hub that wheel hub electric motor of electric vehicle uses at present is in following disadvantage:
The wheel hub magnetic guiding loop iron ring of common electric vehicle motor is using very big wall thickness as magnetic conduction and to place fastening screw hole, very big
Wall thickness causes hub weight to lay particular stress on, and irony machining period and precision are not so good as to be easily worked on low-density alloy metal；In addition, wheel
Hub magnetic guiding loop iron ring is thick and heavy also to promote motor assembly weight higher.
As shown in Figure 1, G meaning position is wheel hub magnetic guiding loop iron ring for conventional ordinary motor wheel hub, have very big
Wall thickness is generally arranged at magnetic guiding loop iron ring for installing electric motor end cap screw hole, which lay particular stress on hub weight.
Summary of the invention
The purpose of the present invention is to provide electric vehicle motor lightweight wheel hub is used for, to solve existing common electric vehicle electricity
Wheel hub lays particular stress on problem, and has intensity higher, the good feature of performance.
To solve the above-mentioned problems, the invention provides the following technical scheme:
A kind of lightweight motor of electric motor car wheel hub, including wheel rim, plural former and magnetic guiding loop iron ring, it is characterised in that: institute
The plural subplate stated, which is arranged in wheel rim inner ring lateral wall and extends to wheel rim outer ring inner sidewall to external radiation, forms regular distribution, institute
The wheel rim and plural subplate stated are integrally formed, and magnetic guiding loop iron ring interference fit is built on the inside of wheel rim inner ring, and the plural number is secondary
A locking part is formed with wheel rim inner ring junction on plate, the screw to install electric motor end cap is provided on the locking part
Hole, the wall thickness of the magnetic guiding loop iron ring is between 2.5-3mm.
Further, many places wall thickness of the wheel rim is the distribution of not uniform thickness, and wall thickness section is between 3-3.5mm.
Further, screw hole is not provided on the magnetic guiding loop iron ring, magnetic conduction iron ring and screw hole keep 0.5-1mm
Spacing.
Further, the wheel rim valve port for being used to install tire, the valve bore dia are 9.5mm, are suitable for
It is used in narrow dimension rim width, guarantees cycle valve of vacuum tire air-tightness, and convenient for machining.
By said structure design, the thickness of magnetic guiding loop iron ring reduces, and the screw hole to install electric motor end cap is arranged
On the locking part formed on plural subplate with wheel rim inner ring junction, the processing of screw hole is more accurate, by above-mentioned effectively light
The motor of electric motor car wheel hub that Quantitative design optimized, and finite element analysis technology is used, quantity of material is rationally set, wheel hub is made to exist
In the case that proof strength is constant, weight obtains maximizing loss of weight.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of prior art wheel hub magnetic guiding loop iron ring；
Fig. 2 is the structural upright schematic diagram of the motor of the embodiment of the present invention；
Fig. 3 is the structural profile illustration of the embodiment of the present invention；
Fig. 4 is the structural front view (left view) of the embodiment of the present invention.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in Fig. 2 ~ 4, a kind of lightweight motor of electric motor car wheel hub, including wheel rim 1, plural former 2 and magnetic guiding loop
Iron ring 3, wheel rim 1 are made of outer ring 11 and inner ring 12, and the plural subplate 2 is arranged in 12 lateral wall of wheel rim inner ring and outside spoke
It penetrates and extends to 11 inner sidewall of wheel rim outer ring and form regular distribution, the wheel rim 1 and plural subplate 2 are integrally formed, magnetic guiding loop iron
3 interference fit of circle is built in 12 inside of wheel rim inner ring.A locking is formed on the plural subplate 2 with 12 junction of wheel rim inner ring
Portion 21 is provided with the screw hole 4 to install electric motor end cap, and 2 quantity of former and 4 quantity of screw hole on the locking part 21
It is equal.
The wall thickness of the magnetic guiding loop iron ring 3 first used in the embodiment of the present invention is between 2.5-3mm；The wheel rim outer ring
11 many places wall thickness is the distribution of not uniform thickness, and wall thickness section is between 3-3.5mm, as shown in B and C in Fig. 3.The magnetic guiding loop
Screw hole is not provided on iron ring 3, magnetic guiding loop iron ring 3 and screw hole 4 keep 0.5-1mm spacing as shown atd.
In conclusion the present invention relates to a kind of wheel hub structure of electric vehicle, by subtracting the thickness of magnetic guiding loop iron ring
It is small, it will be arranged on the locking part formed on plural subplate with wheel rim inner ring junction to the screw hole for installing electric motor end cap,
The processing of screw hole is more accurate, can avoid serious assembly error, while processing up to fast turning, and can reduce excessive
Waste cut materials, it is whole to reduce manufacturing cost, and the wheel hub and a plurality of disc directly form the locking part of end cap, can increase end cap
The intensity of locking, and the thickness of wheel hub can be reduced, and then the weight of Integral hub can be reduced.
The above is only the better embodiment of invention, not makes any form of restriction to invention, all foundations
Technical principle of the invention any simple modification, equivalent variations or modification made to the above embodiment, still fall within skill of the present invention
In the range of art scheme.
