Point.
Detailed description of the invention
Quoting making each embodiment of the present invention in detail now, the example of these embodiments is displayed on
In accompanying drawing and be described as follows.Although the present invention will combine with illustrative embodiments and be described, it will be appreciated that this
Description is not intended to limit the invention to those illustrative embodiments.On the contrary, it is contemplated that not only cover these and show
Example embodiment, and within covering can be included in the spirit and scope of the present invention being defined by the appended claims
Various selection forms, modification, the equivalent form of value and other embodiment.
Hereinafter, with reference to accompanying drawing, the preferred embodiment of the present invention will be described in detail.
As shown in Figures 3 to 5, transmission for a vehicle 10 includes gearbox case.Gearbox case includes variator
Housing 11 and back cover 13, this case of transmission 11 comprises each element wherein and protects them, and variator closed by this back cover 13
The rearward end that housing 11 opens wide.Inventive feature is mainly to increase the coupling force between variator 10 and car body 40.
To achieve the above object, in an exemplary embodiment of the present invention embodiment, transmission mounting bracket 20 joins simultaneously
Receive case of transmission 11 and back cover 13 (this back cover 13 is attached to case of transmission 11).It addition, transmission mounting bracket 20 leads to
Cross bolt 31 and be attached to insulating part 30, and insulating part 30 is attached to car body 40.
In other words, transmission mounting bracket 20 is installed in the following manner to variator 10, and which refers to variator
Mounting bracket 20 couples upper end and the rear surface of back cover 13 of variator 11 simultaneously, and the rear surface of this back cover 13 is towards car body
40。
In details of the words, transmission mounting bracket 20 is attached to case of transmission by bolt 50 at least four interface
The upper end of 11.Transmission mounting bracket 20 is attached to back cover 13 by bolt 60 at least one interface.
Additionally, the position that transmission mounting bracket 20 couples with back cover 13 is preferably the upper end of neighbouring case of transmission 11
Portion.Reason for doing so is that, it can make the coupling force between transmission mounting bracket 20 and back cover 13 maximize.
If it is to say, low than shown in Fig. 3 of the position that is fastened in back cover 13 of bolt 60, then along with this position
Further away from the upper end of case of transmission 11, between the transmission mounting bracket 20 produced by bolt 60 and back cover 13
Coupling force will reduce.In order to avoid this problem, and make the coupling force between transmission mounting bracket 20 and back cover 13
Maximize, in the position of the upper end of neighbouring case of transmission 11, transmission mounting bracket 20 is attached to back cover by bolt 60
13。
The variator using to realize the above-mentioned architectural feature of the present invention in an exemplary embodiment of the present invention embodiment is installed
Support 20 includes substrate 21, rear flange 23 and flange boss 25.Substrate 21 is attached to case of transmission 11.Rear flange 23 is from substrate
21 bendings also extend therefrom, and rear flange 23 is attached to insulating part 30 by bolt 31.Flange boss 25 extends from rear flange 23
Being coupled to back cover 13, this back cover 13 is attached to case of transmission 11.Insulating part 30 is fixed to car body 40.
Substrate 21 is fixed to the upper end of case of transmission 11.Flange boss 25 downwardly extends from substrate 21, and is fixed to
Rear surface towards the back cover 13 of car body 40.Substrate 21 has at least four bolt hole 21a, and bolt 50 is by described bolt hole
21a and be fastened in case of transmission 11, thus substrate 21 is fixed to the upper end of case of transmission 11.Flange boss 25 has
There is at least one bolt hole 25a, and bolt 60 is fastened in back cover 13 by this bolt hole 25a, thus by solid for flange boss 25
The fixed rear surface to back cover 13.
Additionally, be preferably configured to according to the transmission mounting bracket 20 of exemplary embodiment of the invention: along car body
Longitudinal direction be formed with step part 21b at the middle part of substrate 21, thus improve the intensity of support 20.It addition, at substrate 21
Both sides of the edge on be provided with side flange 27, to strengthen described support 20, so that described side flange 27 is integrally connected to base
Plate 21 and rear flange 23.
So, in an exemplary embodiment of the present invention embodiment, transmission mounting bracket 20 includes flange boss 25 so that when
When the substrate 21 of transmission mounting bracket 20 is attached to the upper end of case of transmission 11, flange boss 25 is attached to towards car body
The rear surface of the back cover 13 of 40.Thus, (transmission mounting bracket 20 passes through bolt 50 at this interface for car body 40 and interface M2
Be attached to variator 10 at M2) between minimum range L2 significantly reduce.Therefore, variator 10 is attached to the power energy of car body 40
Enough increase significantly.
In other words, in the conventional technology, transmission mounting bracket 20 is only attached to the upper end of case of transmission 11,
So that car body 40 and interface M1 (transmission mounting bracket 20 is attached to case of transmission 11 at this interface M1) it
Between minimum range be L1.
But, in an exemplary embodiment of the present invention embodiment, transmission mounting bracket 20 is concurrently coupled to case of transmission
The upper end of 11 and back cover 13.Thus, (transmission mounting bracket 20 is connected at this interface M2 for car body 40 and interface M2
Variator 10) between minimum range be that L2, L2 are less than the L1 of conventional art.
So, minimum range L2 between the interface M2 of car body 40 and variator 10 is than the minimum range of conventional art
Time much smaller, the coupling force between variator 10 and car body 40 can increase a lot compared with conventional art, especially in view of passing
Move during the weight of system all the more so.Therefore, produce during the present invention can reliably reduce oil pump, belt and operated gear
And it is delivered to vibration and the noise of car body 40.
Therefore, in an exemplary embodiment of the present invention embodiment, owing to increasing the connection between variator 10 and car body 40
Power, it is possible to significantly decrease vibration and noise produced by the operation of the power train in car body 40.Such that it is able to increase
Add consumer's preference for vehicle, and and then the merchantability of raising vehicle.
Fig. 6 shows the analysis of the vibration produced in car body 40 when oil pump operates.In the frequency band A1 of about 1000Hz,
The amplitude maximum of the vibration owing to producing in the caused car body of the operation of oil pump 40.Measurement from the frequency band A1 of about 1000Hz
Result is it can be seen that the mounting structure of the present invention is compared with the mounting structure of conventional art, it is possible to reduces and vibrates about 10dB.
Additionally, the amplitude of noise that Fig. 7 is showing the operation of belt due to power train and produces in car body 40
Chart.In the frequency band A2 in the range of about 750Hz to about 1100Hz, belt the amplitude maximum of the noise produced.
By the measurement result in the frequency band A2 in the range of about 750Hz to about 1100Hz it can be seen that the installation of the present invention
Structure is compared with the mounting structure of conventional art, it is possible to reduces and vibrates about 10dB.
Meanwhile, in figures 4 and 5, during reference 29 represents the rear flange 23 being formed at transmission mounting bracket 20
Bolt hole.It is fastened in this bolt hole 29 for coupling the bolt 31 of insulating part 30.
As it has been described above, in an exemplary embodiment of the present invention embodiment, transmission mounting bracket can strengthen variator and car
Coupling force between body.Accordingly, because the operation of power train causes the vibrating noise produced in car body to significantly decrease, from
And improve consumer's preference for vehicle.
