Technical field
The invention belongs to vehicle drive-train technical field, and in particular to a kind of wheel set for including wheel hub motor.
Background technology
In vehicle drive-train field, distribution driving is an important technological development direction.At present, distributed driving
Structure type be broadly divided into two kinds：Wheel motor structure and hub motor structure.Compared to wheel motor, the collection of wheel hub motor
Into changing, degree is higher, and driving-chain is shorter, more efficient, but has larger unsprung mass, smooth-going of this point for vehicle
Property have a certain impact, it is necessary to be made up by carrying out certain adjustment to suspension design parameter.Meanwhile, wheel hub motor eliminates ten thousand
To transmission mechanism, make the arrangement of chassis and suspension freer, also make it that the distribution of power is more accurate and free, Neng Gougeng
The torque output of four-wheel is controlled well, and then controls the yaw moment of vehicle, improves the control stability of vehicle.
However, being arranged in compared to by motor on automobile chassis, motor is arranged in power of the inside wheel for motor
Higher requirement is proposed with torque density, otherwise excessive unsprung mass can not be by right for influence possibly of ride comfort
The complete effacement of improvement of suspension frame structure is fallen.Meanwhile, motor is arranged in inside wheel so that the installation pedestal of motor lacks elasticity
The support of element and damping original paper, the vibrations that expanded motor is subject to.And the vibrations that motor is subject to can cause motor stator with turning
Gap change between son, causes the motor gas-gap distortion of field, after rotating speed is raised to a certain extent, the amplitude of imbalance vibrations
It is possible to exceed protection air gap, in turn results in the damage of motor.
Therefore, consideration for 2 reasons above to wheel set inside, it is necessary to carry out damping processing.So on the one hand
A part of unsprung mass can be equivalent to the ride comfort in sprung mass, lifting vehicle operation；On the other hand it can subtract
Impact suffered by the parts such as light motor, effectively improves vehicle reliability of operation and reduces vehicle maintenance cost.
Current wheel hub motor scheme does not often install damping additional for motor, and motor is entered only by suspension system
The a certain degree of damping of row, also or individually in motor internal installing damping device.Thus unsprung mass is larger, it is difficult to meet car
The requirement of ride comfort.Meanwhile, the damping device installed additional can increase the free degree of inside wheel structure, the mistake travelled in vehicle
The change of wheel parameter is caused in journey.

Sun gear 27 inputs planetary reducer, and gear ring 16 maintains on-position, and wheel is output to by planetary gear 26 and planet carrier 1
Rim 10, driving moment.Planetary reducer is slowed down using the rotating ratio of planet carrier and sun gear 27, is turned round while improving output
Square refers to Fig. 1 transmission sketch to adapt to vehicle demand.
(2) during wheel hop power transfer route：During vehicle is travelled, the vibrations meeting that road excitation is produced
By tire, spoke 10 and wheel rim 8 are delivered on wheel hub i.e. planet carrier 1, and planet carrier 1 transfers force to planetary gear shaft
I.e. on connecting bolt 24 and planetary gear 26, and sun gear 27 and outer rotor hub motor 1 are passed to by planetary gear 26；
On the other hand, part vibrations are also delivered on the housing 11 that gear ring 16 and gear ring 16 are connected in by planetary gear 26.Most
Eventually, all vibrations are all collected on housing 11 and are further transferred on steering column 7.To avoid suspension and turning on column 7
The reaction force being subject to exerts an adverse impact to the outer rotor hub motor 1 in operating, is turning between column 7 and housing 11
It with the addition of flexible member 36 and carry out damping.But the increase of flexible member 36 also increases the freedom of motion of Electric Motor Wheel inner member
Degree so that there may be large change, meeting in vehicle travel process for wheel alignment parameter (such as wheel leaning angle, wheel beam angle)
Control stability generation to vehicle has a strong impact on.Therefore the freedom of motion of constraint Electric Motor Wheel inner member is needed, by elasticity
Element 36 is placed between housing 11 and steering column 7, and outer rotor hub motor 1 and planetary reducer are integrally carried out at damping
Reason, and mating surface is designed between housing 11 and steering column 7, further outer rotor hub motor 1 and planetary reduction gear are filled
The freedom of motion put is limited in vertical direction.Meanwhile, corresponding damping force can be also provided inside flexible member 36.Refer to figure
Structure in 2.
Unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
