Description
Technical field
It the utility model is related to automobile technical field, more particularly to a kind of automotive transmission mounting bracket and automobile.
Background technology
Speed changer suspension system is part indispensable in vehicle structure, between speed changer and vehicle body, mainly
For supporting speed changer and reduction speed changer to be delivered to the vibration of vehicle body, to the noise of automobile, vibration and sound vibration roughness
(Noise, Vibration, Harshness, referred to as NVH) performance has decisive influence.
In the prior art, speed changer suspension system mainly includes rubber mount and metallic support, and metallic support is used to support
Speed changer and transmission are vibrated, and rubber mount is arranged between metallic support and vehicle body, for absorbing coming from for metallic support transmission
The vibration of speed changer excitation.But the rubber mount absorption vibration efficiency using the speed changer suspension system of this technology is relatively low, its
Often strength and stiffness are insufficient for metallic support, and intrinsic frequency is too low, and easily will be coupled if intrinsic frequency is too low with excitation,
When the driving frequency of speed changer and the close or equal intrinsic frequency of metallic support, covibration can be produced, and is being resonated
Under frequency, the periodic vibration of very little can produce very big vibration, have a strong impact on the NVH performances of automotive transmission suspension system.
Thus, it is the defects of this technology:The NVH degraded performances of automotive transmission suspension system.
Utility model content
The purpose of the utility model embodiment is to provide a kind of automotive transmission mounting bracket structure and automobile, solved
The problem of existing transmission suspension supporting structure NVH degraded performances.
For the above-mentioned purpose, the utility model embodiment provides a kind of automobile and drags transmission suspension structure, rack body, institute
Stating rack body includes the first vehicle body connecting portion, the second vehicle body connecting portion and speed changer connecting portion, the first vehicle body connecting portion
Shape with the second vehicle body connecting portion is L-shaped, and the both ends of the speed changer connecting portion connect with first vehicle body respectively
Socket part is fixedly connected integrally with the second vehicle body connecting portion；
Bracket reinforcing plate, the both ends of the bracket reinforcing plate respectively with the first vehicle body connecting portion and second vehicle body
Connecting portion is fixedly connected, and the top of the bracket reinforcing plate is fixedly connected integrally with the bottom of the speed changer connecting portion.
The utility model embodiment also provides a kind of automobile, including the automotive transmission that the utility model embodiment provides hangs
Put supporting structure.
Beneficial effect is caused by the utility model：By improving the intrinsic frequency of automotive transmission mounting bracket structure,
The generation of covibration is reduced, so as to improve the NVH performances of automotive transmission suspension system.
