Description
Technical field
The present invention relates to drive system of electric automobile, in particular to a kind of integrated Electric Motor Wheel of electric wheel of internal rotor to drive
Dynamic system.
Technical background
With the exacerbation of energy shortage and problem of environmental pollution, Devoting Major Efforts To Developing energy conservation and the new-energy automobile of environmental protection are had become
The inevitable choice of current China Automobile Industry.Pure electric automobile outstanding advantages efficient with its, pollution-free, low noise are in recent years
It is rapidly developed.In-wheel motor driving formula electric car is in vehicle general arrangement structure optimization, chassis active control and manipulation
The obvious technical advantage of convenience etc. makes it by the common concern of industry and academia.
The chassis structure of hub motor driven electric vehicle concentrates motor-driven vehicle chassis structure dramatically different with tradition,
The height such as motor, deceleration mechanism, brake is integrated in wheel by it, the reference of novel chassis structure, needs to carry out completely not
It is same as the structure innovation of traditional electric car.The especially integrated design of In-wheel-motor driving system, as hub motor
Drive the core technology of electric car, the superiority and inferiority of structure and performance directly affects the driving/braking performance of each driving wheel and whole
The driving performance of vehicle.
Design for In-wheel-motor driving system needs to collect the height such as hub motor, brake and other connecting components
At and reasonable Arrangement in narrow wheel.Therefore, structure and limitation spatially, it is desirable that the design of In-wheel-motor driving system is not
Only to consider vehicle traction/braking requirement, also to fully consider cooling and the sealing problem of system, just can guarantee hub motor
The normal operation of drive system and vehicle.In addition, being limited by space and running environment, simultaneously because drive required when low speed
Dynamic torque is very big, and at present hub motor in a limited space with that the required high torque (HT) of vehicle working condition is extremely difficult under environment is close
The design requirement of degree, and one of solving the problems, such as this effective ways is exactly the setting deceleration mechanism in electronic wheel system, this has no to doubt
Ask the design difficulty that can further increase In-wheel-motor driving system, meanwhile, the increase of component further increases nonspring carried mass,
The ride comfort, riding comfort and handling stability of vehicle will be had adverse effect on.In addition, at present for In-wheel-motor driving system
Design be specifically to be designed for the tire of a certain producer/model so that designed In-wheel-motor driving system
Versatility is poor, the unfavorable popularization and application with In-wheel-motor driving vehicle.Therefore, how to guarantee In-wheel-motor driving system dynamic
On the basis of energy, the sealing, cooling, lightweight problem of electronic wheel system are fully considered, developing, there is the Electric Motor Wheel of versatility to drive
Dynamic system is one of current wheel hub driving Development of Electric Vehicles problem encountered.
Based on this, the present invention proposes a kind of integrated structure of electric wheel of internal rotor and assembly method.This electronic train
System has fully considered the versatility of the cooling of demand, drive system of the vehicle to dynamic property, sealing, lightweight and electronic wheel system
Problem has carried out integrated design scheme to electronic wheel system, and its assembly method has been illustrated.
Summary of the invention
The present invention proposes a kind of integrated structure of electric wheel of internal rotor, to hub motor, deceleration mechanism, brake and
Other connecting components have carried out integrated design, this organization plan uses two reduction gear scheme, low to meet vehicle
The demand of fast large torque, while the problems such as comprehensive arrangement for considering wheel hub space and deceleration, braking, vibration damping, cooling.The present invention
Provide that a kind of integrated level height, good dynamic property, light weight, thermal diffusivity be good and versatility with higher it is integrated electronic
Wheel system.
The purpose of the present invention is achieved through the following technical solutions:
The integrated structure of electric wheel of internal rotor proposed by the present invention, mainly has primary speed-down hub motor, planet to subtract
Fast mechanism, arrestment mechanism, damping, cooling body, wheel hub and tire are constituted.Hub motor mainly have stator and coil around
Primary planet pinion deceleration mechanism and motor housing composition inside group, rotor and permanent magnet and motor；Deceleration mechanism includes
Two-stage, primary speed-down is in motor interior design, and double reduction is embodied in the planetary gear speed-reduction in outside, and structure is mainly by planet
Frame, gear ring, sun gear, planetary gear set at.The power input of primary speed-down mechanism derives from rotor, and internal rotor designs a tooth
Circle is rotated by rotor power passing to planetary gear by rotor gear, and sun gear, which is connected by key, to be fixed in fixing axle,
Planetary gear imparts power to planet carrier again, and with output power, the power resources of two reduction gear are in sun gear, double reduction
The sun gear of mechanism and the planet carrier of primary speed-down mechanism are designed as an entirety, ensure that the continuity of power, sun gear
Power is transmitted to planetary gear, gear ring is fixed, then planet carrier output power, and planet carrier is connected with wheel hub, drives vehicle forward；
Selected brake is disk brake, and brake disc selects to use the planet carrier disk of two reduction gear, and caliper is mounted on motor
Enclosure interior；Damping is mainly made of rubber element, be separately mounted between hub motor shell and support shaft, stator and
Between coil windings and electric machine casing and between planetary mechanism planet carrier and wheel hub；Cooling body is using the cooling and oil duct that splashes
Cooling combines, and is on the one hand acted on by the centrifugal force of rotating member oil liquid splashing mechanism everywhere, plays cooling and lubrication work
With；On the other hand mainly winding coil is cooled down, a thin-walled oil jacket is designed on the outside of winding coil, by the cold of oil jacket
But the cooling to winding is completed indirectly；In terms of the assembly of entire mechanism, the entire mechanism of planetary gear reduction system is with fixing axle
For supporter, motor housing is fixed on axis, and after entire mechanism assembly is completed, the planet carrier of two reduction gear passes through wheel
Hub terminal pad is directly connect with rim bolt, and power is made to be transmitted to wheel.
The working principle of the invention:
