Abstract
The utility model discloses Axile connection structure after a kind of hub motor for electric automobile, including：Brake, wheel hub motor, adapter flange dish, described brake is made up of caliper, brake disc, and caliper, brake disc are mutually matched, described brake disc is bolted with wheel hub motor, described adapter flange dish are bolted with wheel hub motor, and described caliper is bolted with adapter flange dish.The utility model is using brake and the bolted mode of wheel hub motor, and brake efficiency is high, and cost is low.
Description
Technical field
It the utility model is related to wheel hub motor mounting technique field, axis connection after specially a kind of hub motor for electric automobile
Structure.
Background technology
Wheel hub motor technology is also known as wheel inner electric machine technology, and its maximum feature is exactly by power, transmission and braking dress
Put and be all incorporated into wheel hub, therefore the mechanical part of electric vehicle is greatly simplified.Wheel hub motor technology is not new things, early
In 1900, be just manufactured that front-wheel equipment wheel hub motor electric automobile, in the 1970s, this technology in ore deposit
The fields such as mountain transport vehicle are applied.And opened for the wheel hub motor used in passenger car, Japanese manufacturer for technique research and development
Exhibition is more early, is currently in leading position, and the international automobile giant including general, Toyota also has involved to the technology.
In-wheel motor driving system is largely divided into two kinds of structural shapes according to the rotor type of motor：Inner-rotor-type turns with outer
Minor.Wherein external-rotor-type uses low speed external rotor electric machine, and the maximum speed of motor is in 1000-1500r/min, no dress that slows down
Put, the rotating speed of wheel is identical with motor；And inner-rotor-type then uses high speed inner rotor motor, the deceleration of fixed drive ratio is equipped with
Device, to obtain higher power density, the rotating speed of motor may be up to 10000r/min.With more compact planetary gear speed-reduction
The appearance of device, inner-rotor-type wheel hub motor are more more competitive than low speed external-rotor-type in terms of power density.
Brake is integrated in wheel hub motor by existing wheel hub motor, complicated, and brake efficiency is poor.
Utility model content
The purpose of this utility model is to provide Axile connection structure after a kind of hub motor for electric automobile, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：A kind of hub motor for electric automobile rear axle connects
Binding structure, including：Brake, wheel hub motor, adapter flange dish, described brake are made up of caliper, brake disc, and are braked
Pincers, brake disc are mutually matched, and described brake disc is bolted with wheel hub motor, described adapter flange dish and wheel hub electricity
Machine is bolted, and described caliper is bolted with adapter flange dish.
Compared with prior art, the beneficial effects of the utility model are：The utility model discloses a kind of electric car wheel
Hub electric motor back shaft attachment structure, brake therein are made up of caliper, brake disc, are connected using brake and wheel hub motor bolt
The mode connect, brake efficiency is high, and cost is low.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
In figure：1- wheel hub motors；2- adapter flange dish；3- calipers；4- brake discs.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides Axile connection structure after a kind of hub motor for electric automobile, including：Brake,
Wheel hub motor 1, adapter flange dish 2, described brake are made up of caliper 3, brake disc 4, and caliper 3, brake disc 4 are mutual
Matching, described brake disc 4 are bolted with wheel hub motor 1, and described adapter flange dish 2 pass through spiral shell with wheel hub motor 1
Tether and connect, described caliper 3 is bolted with adapter flange dish 2.
Operation principle：The utility model discloses Axile connection structure after a kind of hub motor for electric automobile, braking therein
Device is made up of caliper, brake disc, and using brake and the bolted mode of wheel hub motor, brake efficiency is high, and cost is low.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
