Stabilizer bar assembly 6 between vehicle frame 3, so as to ensure stability of the vehicle when turning to.Plate wherein in present embodiment
Spring assembly 44 and stabilizer bar assembly 5 are component well known in the art, structure and are existed with the connection mode of associated components
This, which does not do, excessively repeats.In addition, in this illustrative embodiments, the suspension system that the disclosure provides includes being connected to bridge
The second damping between shell 1 and vehicle frame 3, for example, damper, plate spring assembly being connected between axle housing 1 and vehicle frame 2 etc. with
For stablizing axle housing 1.
In this illustrative embodiments, the second damping includes the first damper 41 and the second damper 42, excellent
It selects in embodiment, the first damper 41 and the second damper 42 are symmetrically located at 2 both sides of driving motor, i.e., are pair with driving motor
Title center is connected between axle housing 1 and vehicle frame 2.In other variant embodiments, 42 nothing of the first damper 41 and the second damper
It need to be defined as being symmetrically located at 2 both sides of driving motor, it is only necessary to be connected between axle housing 1 and vehicle frame 3 or stabilizer bar
Cushioning effect is played to vehicle frame and axle housing between assembly 6 and vehicle frame 3.
First damping includes third damper 43, which is located at the first damper and the second damper
On symmetrical centre face.Symmetrical centre face described herein refers to that two linear dampers are symmetrical about the median plane.So as to
So that three dampers are more uniform to the stabilization of drive axle, effect is more preferable.Certainly in other variant embodiments, third
Damper is also without being defined on the symmetrical centre face of the first damper and the second damper, as long as such as third damper
Between the first damper and the second damper, as long as third damper is formed with the first damper and the second damper for another example
Triangle is with to axle housing and vehicle frame, driving motor and vehicle frame progress damping stabilization.
Further, 43 and first damper 41 of third damper and the second damper 42 are arranged in isosceles triangle, i.e.,
The rock-steady structure of supported at three point is formed, wherein three dampers described herein are arranged in isosceles triangle, is referred to any one
On a horizontal plane, the section of three dampers is located on three angles of isosceles triangle respectively, due to the first damper and second
Damper is symmetrical, therefore third damper is located on the apex angle of the isosceles triangle.In this way, the first and second dampers can have
Effect is stablized for axle housing 1, and third damper 43 is then stablized for driving motor 2, and three passes through isosceles triangle
It is arranged such that the stability of integrated motor drive axle is more preferable, axle housing 1 can be protruded from and cause matter by being particularly suitable for driving motor 2
The structure of the motor drive axle of heart offset problem, so as to ensure the comfort of vehicle.In other possible embodiments, third
Damper be also possible to while on symmetrical centre face it is coplanar with the first and second dampers, in addition, the second damping
The damping of other types well known in the art can also be respectively formed as with the first damping.
Wherein in the present embodiment, as shown in Figure 1, the first damper 41, the second damper 42 and third damper 43
Can be bitubular hydraulic damper, as an example, its operation principle is to work as phase occurred by vibrations between vehicle frame or vehicle body and drive axle
During to movement, the piston in damper moves up and down, and the fluid in snubber cavity just repeatedly passes through different holes from a chamber
Clearance flow enters another intracavitary.Friction between hole wall and fluid at this time and the intermolecular interior friction of fluid form damping force to vibrations,
Vibration energy is made to be converted into fluid thermal energy, then is dispersed into air by absorber.In addition, the first damper 41, second subtracting
Shake device 42 and third damper 43 can also be the spring damper that damping is realized by spring.In other embodiments, ability
Various dampers can be applied to the disclosure in domain.
Wherein no matter the damper of fluid pressure type or spring, as shown in Figure 1, in order to realize the third damping of linear structure
The installation of device 43, the upper end of the third damper 43 are hinged on by the first bearing 51 on vehicle frame 3, and lower end passes through the second bearing 52
It is hinged on the housing of driving motor 2.It can be movable connection method that can ensure third damper both ends in this way, so as to
Adapt to the irregular vibrations of the drive axle in vehicle travel process.
Specifically, as shown in Figure 1, the first bearing 51 is formed as U-shaped structure, i.e., including bottom wall and positioned at the side of bottom wall both sides
The bottom wall of wall, the wherein U-shaped structure carries out detachable consolidate for being fixedly linked with vehicle frame, such as by fasteners such as bolts
Determine or be welded direct on vehicle frame.And of the upper end for hinged third damper 43 is then connected between its two side
One axis pin, first axis pin can be formed with bolt, and the upper end of wherein third damper 43, which could be formed with, to be rotationally socketed
Hinge hole outside first axis pin, so as to fulfill the installation of the two radial type.
In addition, as shown in Figure 1, for the ease of being connected on the housing of driving motor 2, the second bearing 52 is formed as L-shaped knot
Structure, one end and the housing of the L-shaped structure are fixedly linked, and the other end is provided with hinged seat 53, are connected with to cut with scissors on the hinged seat
Connect the second axis pin of the lower end of third damper 43.Second bearing of wherein L-shaped structure can be formed as platy structure and adopt
With arc-shaped transition inflection, on the one hand the position of the second axis pin is allowd to be drawn outward from housing and avoid the structure of motor in itself
And convenient for setting hinged seat 53, on the other hand, the intensity of the L-shaped structure of arc plate can be guaranteed, so that third
The installation of damper is stablized.
Wherein, the structure of hinged seat 53 can be similar with the structure of the first above-mentioned bearing, can be L-shaped structure and with
U-shaped structure is collectively formed in second bearing, wherein the second bearing can as a side wall of the U-shaped structure, such L-shaped structure
The second axis pin can be connected between side wall and the second bearing, it is hinged to be realized with the lower end of third damper 43.
In addition, in the exemplary embodiment, in order to promote the damping effect of third damper, third damping can be designed
The angle of inclination of device vertically is not more than 20 °, also in the symmetrical centre of the first damper and the second damper after tilting
On face.In a preferred embodiment, the angle of inclination of third damper vertically is not more than 10 °, and more preferably, third subtracts
Shake device is arranged in a vertical direction, such as is realized by the first bearing in above-mentioned and the second bearing, so that third damper
Can perpendicular to horizontal vehicle frame, can more effectively power transmission and damping, the component on other directions will not be generated.
The preferred embodiment of the disclosure is described in detail above in association with attached drawing, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical solution of the disclosure
Monotropic type, these simple variants belong to the protection domain of the disclosure.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the disclosure to it is various can
The combination of energy no longer separately illustrates.
In addition, arbitrary combination can also be carried out between a variety of different embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought should equally be considered as disclosure disclosure of that.
