It is integrated into wheel hub, simplifies the structure of vehicle.However, such integration is proposed the design of brake with dismounting and chooses
War, but all fail to obtain good solution.
Invention content
The main inventive purpose of the present invention is to design a kind of wheel hub motor brake suitable for new-energy automobile.
Technical solution used in the present invention is：A kind of holder breakaway-element floating guiding pin fission braking of wheel hub motor
Device, including brake disc, holder, guide pin, upper clamp, lower clamp, upper friction plate, lower friction plate, piston and guide sleeve.Upper clamp
It is fixed together with lower clamp.Guide pin and upper clamp are fixed together.Holder includes two U-shaped rack bodies, holder master
The connecting portion of body is located at the inner circle side of brake disc, and the two side walls of rack body extend to the outer circle of brake disc, holder master
The free end of the two side walls of body is located at outside the outer circle of brake disc, the free end of the upper surface of two rack bodies two side walls
Respectively with the both ends of upper connecting rod be connected, below two rack bodies the free end of two side walls respectively with lower connecting rod
Both ends are connected；Two rack bodies of holder are respectively fixed together with vehicle frame.Upper clamp and lower clamp are set after being fixed together
Between two rack bodies.Guide sleeve is equipped with and the pilot hole of guide pin adaptation, and the lower end of guide pin is plugged on pilot hole
In, guide sleeve and holder are connected.Upper friction plate and lower friction plate are located at the top and lower surface of the upper surface of brake disc
Lower section, upper friction plate and holder activity cooperation, lower friction plate and holder activity cooperation；Piston cylinder is housed on upper clamp.Upper clamp
It is equipped with the fuel feed hole being connected to piston cylinder and the parking system interface for EPB or IPB；Brake disc is pacified equipped with several brake discs
Fill hole.
" upper friction plate and holder activity cooperation, lower friction plate and holder activity cooperation " refer on during automobile moves
Upper and lower friction plate and brake disc are phase separations and static, and upper and lower friction plate is to move towards and be adjacent to braking in braking
Disk is upper and lower surfaces of.That is, pushing piston to eject upper friction plate by fuel feed hole input brake oil, high pressure oil when braking, making it
It contacts and compresses with the upper surface of brake disc；With the increase of oil pressure, the caliper group and guide pin of upper clamp and lower clamp composition
It is moved together along brake disc axis direction, to drive lower friction plate to contact with the lower surface of brake disc, causes to rub above and below
Piece clamps brake disc, achievees the purpose that braking.Wherein, because being fixed together again after upper clamp and lower clamp separately manufacturing, together
When two rack bodies be located at the position of brake disc inner circle one end and be not connected together between each other with corresponding component, also
It is to replace where the meaning of " holder breakaway-element " and safeguard friction plate there is no need to first move holder.And holder in existing holder
The connected position of main body is provided at the inner circle side of brake disc, and two rack bodies are located at the upper arm of the side of brake disc outer circle
It is connected between upper arm and between underarm and underarm, to replace and safeguard that friction plate just needs first to move holder, in operation very
It is inconvenient.Therefore, the present invention has the dismounting for facilitating brake and according to brake disc and the size of friction plate, abrasion condition,
The advantages of adjusting upper and lower caliper and friction plate has the advantages that manufacture, installation, maintenance are easy, and solves original wheel hub motor and uses
The corresponding significant drawbacks of holder.Therefore, the present invention is a kind of very outstanding seperated brake.
Preferably, upper clamp and lower clamp are fixed together using fixing bolt.Guide pin and upper clamp utilize connection
Bolt is fixed together.This preferred embodiment, simple in structure, processing and manufacturing and installation are easy.
Preferably, upper clamp is equipped with air vent, bleed screw is fixed on air vent.This preferred embodiment, structure are closed
Reason, easy access are safeguarded.
Preferably, further including having dust cover.The lower end of dust cover is connected with the upper end of guide sleeve, and guide pin passes through dust-proof
It is matched with guide sleeve after cover.Dust cover described here is made by flexible material.Further, the upper end of guide sleeve is equipped with lower company
Concave ring is connect, the lower end of dust cover is connected with lower connection concave ring；Guide pin is equipped with upper connection concave ring, the upper end of dust cover and upper company
Concave ring is connect to be connected.This preferred embodiment advantageously ensures that guide pin and guide sleeve will not be stuck because of dust.
It is fixed together preferably, rack body connects bolt with vehicle frame by vehicle frame.This preferred embodiment, structure letter
It is single, easy disassembling.
In conclusion the beneficial effects of the invention are as follows：It is fixed together, has again after upper clamp and lower clamp separately manufacturing
The easy advantage of manufacture, installation, maintenance.Two rack bodies do not have to be connected with what connecting rod each other in brake disc inner circle side
Get up, show the state mutually disconnected, respectively all connecting bolt by vehicle frame with vehicle frame again is fixed together, it is ensured that
Caliper and more renewal of facing renewal are dismounted under the premise of not removing or moving holder, greatly improve the dismantled and assembled of brake and is safeguarded
Property.Overall structure of the present invention is simple, reasonable, safe and reliable.
