The limitation of scope.
Such as Fig. 1 and Fig. 2, motor 1 has shell 13, and the part of armature spindle 14 is located in shell 13 and by axially spaced
Two bearings 15 of distribution are supported, and the output end 11 of armature spindle 14 is extend out to outside shell 13 from output end end cap 12, are used
Exported in by power.Output end 11 can produce vibration during power output, on the one hand the vibration comes from motor 1 certainly
Body, on the other hand, as shown in Fig. 2 during vehicle travels, because power transmission shaft 5 is longer heavier, when pavement roughness,
Drive axle 6 can drive the bob of power transmission shaft 5, vibration of the bounce equally to causing output end 11.The vibration one of output end 11
Part can be for delivery on vehicle body or vehicle frame, and the noise of vehicle and vibration and driver comfort are all difficult to be guaranteed, another
Part will cause the effect of vibration that the bearing 15 for closing on output end 11 is subject to will greatly very compared to the bearing away from output end 11
It is more, so as to cause the load distribution being subject to of the two bearings 15 very big difference to be present, it is easy to damage.
Vehicle motor fixing device in present embodiment includes fixed structure 2 and Buffer Unit 3, wherein：
As shown in figure 3, in present embodiment, fixed structure 2 is used for the vehicle frame that motor 1 is fixedly attached to vehicle, delays
Rush component 3 to be installed in the output end 11 of motor 1, and can at least partly absorb the vibrational energy in output end 11.Such one
Aspect, which can reduce to be delivered on vehicle frame, to be vibrated, and is so advantageous to improve the noise of vehicle and is vibrated and improve driving comfort
Property, it on the other hand can reduce the difference of load distribution suffered by two bearings 15 inside motor 1, improve the inner shaft of motor 1
15 service life is held, the fault rate of motor 1 is further reduced, improves the service life of motor 1.In addition, present embodiment institute
The fixed structure 2 and Buffer Unit 3 of offer almost played a part of with the suspension on existing vehicle it is suitable, therefore in certain journey
The installation of the suspension on existing vehicle is may be omitted with degree, so as to the workload for avoiding substantial amounts of suspension design and calculating.
In order to which motor 1 is more securely fixed on vehicle frame, fixed structure 2 can be fixedly connected (such as：Welding or
Bolt connection) motor 1 output end end cap 12, such as using face face connect by the way of, i.e., by a side of output end end cap 12
Side of the face completely with the larger area of fixed structure 2 is fixedly connected.Fixed structure 2 is offered through output end 11 and supplied out
The through holes 21 that end 11 rotates, during assembling, output end 11 is passed through into through hole 21, it is simple to operate.Buffer Unit 3 is located at defeated
Go out between end 11 and the hole wall of through hole 21, can be part or all of by the vibrational energy of output end 11 by this setup
Being absorbed and relaxed by Buffer Unit 2, then the vibrational energy that vehicle frame or vehicle body are delivered to by fixed structure 2 remains little, because
This, further improves the noise of vehicle and vibrates and improve driver comfort.
As shown in figure 4, the preferred embodiment as Buffer Unit 2, it includes flexible member 31 and rolling bearing 32, its
In：Flexible member 31 is located between the hole wall of output end 11 and through hole 21 and can at least partly absorb shaking in output end 11
It is dynamic.By the flexible member 31 between output end 11 and fixed structure 2, the vibration and impact that will be applied in output end 11
Elastic absorption is carried out, to play a part of relaxing vibration and impact on vehicle frame.Flexible member 31 can use elastomeric material or tree
The materials such as fat are made, and these materials have the advantage of good buffer effect.The inner ring of rolling bearing 32 is fixedly connected with output end 11,
Outer shroud is fixedly connected with flexible member 31, it is possible thereby to realize that output end 11 is connected to flexible member 31 or solid in a rotating manner
Determine structure 2.Certainly, it is necessary to illustrate, rolling bearing 32 has the low advantage of cost in present embodiment, but the present invention is simultaneously
Do not limit to and rolling bearing, other rotating elements well known in the art can also be used to substitute and realized.
In above-mentioned embodiment, Buffer Unit 3 also includes back-up ring 33, and two back-up rings 33 are separately positioned on rolling bearing 32
Both sides, for preventing rolling bearing 32 from play occurs along the axial direction of output end 11 relative to fixed structure 2.
In above-mentioned embodiment, Buffer Unit 3 also includes sealing ring 34, and sealing ring 34 is arranged in an interference fit
Between the inner ring and outer shroud of rolling bearing 32, for preventing water, dust etc. from entering rolling bearing 32, while rolling bearing 32 is prevented
Lubricating ester or oil stream go out.
In said structure, fixed structure 2 can be accomplished in several ways, and motor 1 is fixed.For example, implement in one kind
In mode, fixed structure 2 includes installation base plate 22 and reinforcing plate 23, wherein：One end of installation base plate 22 is fixedly attached to described
Bottom of frame, side are fixedly connected with the output end end cap 12 of motor 1.The edge of reinforcing plate 23 is fixedly connected with installation base plate 22
Side and the bottom of the vehicle frame.Reinforcing plate 23 can use the triangle reinforcing plate shown in Fig. 3, this structure fabrication process letter
It is single, and fixed form is more firm.
Vehicle motor fixing device in the present invention also includes connection component 4, connection component 4 be arranged on motor 1 with
The relative one end of output end end cap 12, and it is connected to vehicle frame.So just it is respectively provided with the both ends of motor 1 and is connected to vehicle frame
Point, therefore, it can further improve the connection fixing of motor 1.
In above-mentioned embodiment, connection component 4 top surface of motor 1 is connected in a manner of providing upward pulling force vehicle frame or
The bottom surface of motor 1 is connected to vehicle frame in a manner of providing upward support force.
The way of realization that the top surface of motor 1 is connected to vehicle frame by connection component 4 in a manner of providing upward pulling force is more more
Sample, such as：Connection component 4 includes hanger component, the hanger component can include the hanger for being arranged on the top surface of shell 13 and
It is pivotally connected with the hanger and is connected to the connector of bottom of frame, is connected thus, it is possible to the mode being pivoted relative to vehicle frame
Vehicle frame is connected to, upward pulling force is provided for motor 1.By the structure, even export end cap 12 and limited in its radial direction, but
It is to set one end of hanger component to still have certain free degree on motor 1, so to a certain extent can be further
Row buffering is entered to the vibration in output end 11.
The bottom surface of motor 1 is connected to the way of realization of vehicle frame more by connection component 4 in a manner of providing upward support force
It is various, such as：The bottom of the shell 13 of one end relative with output end end cap 12 sets support on motor 1, to enter to motor 1
Row support.
It should be noted that the present invention can also utilize suggested its known in those skilled in the art and of the invention
Its structure for motor 1 provides upward pulling force or upward support force, to realize on motor 1 relative with output end end cap 12 one
End is connected on vehicle frame.
