Abstract

The utility model provides a derailleur mounting structure, includes the casing, fix at the support arm of casing bottom, fix at the bottom plate of support arm bottom, fix the connecting plate at the casing top, its technical essential is: the spacing X of having is to hitting piece and Y to hitting the piece between casing and the support arm, and spacing between support arm and the bottom plate have a main spring, and main spring is the trapezium structure, and main spring lateral wall is equipped with a plurality of through -holes. Fundamentally has solved the not high problem of current suspension system vibration isolation volume, and it has simple structure practicality, installation location accuracy, convenient to use, the frock is with low costs and production cycle such as lacks at the advantage.

Description

Transmission suspension structure
Technical field
This utility model belongs to automobile manufacturing field, specifically a kind of transmission suspension structure.
Background technology
What current domestic passenger car great majority adopted is the arrangement form of three-point suspension, i.e. engine mounting, transmission suspension and toggle suspension.Along with growth in the living standard, people are more and more higher to the performance requirement of car load, and each main engine plants also just increasingly pay attention to NVH performance.And the height of suspension system vibration isolation, directly influence the magnitude of vibrations of steering wheel and seat.For suspension system, be not concerned only with the performance of suspension system during engine idle, also pay close attention to vehicle in the process of running at high speed vehicle gearshift and turn time suspension system to the spacing of power assembly and vibration isolation effect.The transmission suspension of this structure just arises at the historic moment.
Utility model content
The purpose of this utility model is to provide a kind of transmission suspension structure, fundamentally solves the problem that existing suspension system vibration isolation amount is not high, its have simple and practical, accurate positioning is installed, the advantage such as easy to use, frock cost is low and with short production cycle.
For achieving the above object, this utility model provides following technical scheme: this transmission suspension structure includes housing, is fixed on the support arm of housing bottom, is fixed on the base plate bottom support arm, is fixed on the connecting plate of case top, it is characterized in that: spacing between described housing and support arm have X to collision block and Y-direction collision block, spacing between support arm and base plate have main spring, main spring is trapezium structure, and main spring sidewall is provided with some through holes.
The beneficial effects of the utility model: the main spring having manhole provides the rigidity in tri-directions of XYZ for transmission suspension, for meeting the rigidity value in these three directions of suspension in decoupling computation.Z-direction dynamic stiffness and Static stiffness ratio < 1.5, nine manholes also function to the effect of heat radiation while main spring is had an effect, and improve the endurance quality of the main spring of transmission suspension.Improve the vibration isolation effect of transmission suspension, improve the NVH performance of car load.Make power assembly produce in enging cabin smaller spacing, give safe driving sense, improve the NVH performance of car load.Solve the problem that electromotor cycling start is shrugged one's shoulders, be effectively improved the Y-direction position-limiting action of suspension system.

Detailed description of the invention
Below in conjunction with Fig. 1 ~ 4, describe content of the present utility model in detail by specific embodiment.This transmission suspension structure includes inverted U-shaped housing 1, is fixed on the support arm 3 of housing bottom, is fixed on the base plate 5 bottom support arm, is fixed on the connecting plate 6 of case top.Wherein, spacing between housing and support arm have X to collision block 7 and Y-direction collision block 2, and spacing between support arm and base plate have main spring 4, and main spring 4 is trapezium structure, and main spring sidewall is provided with some through holes (being preferably nine).Main spring and collision block are employing Natural rubber and make, it is ensured that provide higher anti-vibration performance under the premise of fatigue endurance.
Collision block contacts with outer housing, but the effect not stressed, after gearing in this part collision block for X to providing certain rigidity value.Collision block contacts with the middle baffle plate on housing, but the effect not stressed, and when vehicle steering wheel rotation in the process of moving, Y-direction collision block provides certain rigidity value for Y-direction.Connecting plate 6 is connected with vehicle body, and purport is improve the dynamic stiffness of vehicle body.Connecting plate 6 and housing 1 make to be connected with, and the spacing rubber of Y-direction and support arm 3 vulcanize, and use base plate 5 and housing 1 to be riveted together after assembling.
X adopts the version of two-stage type to collision block, owing to this partial rubber hardness is less, the ratio that non-linear section in stiffness curve rises is shallower, hang this collision block when shelves travel when vehicle and produce contacting of power with housing, bigger vibration isolation effect is produced while certain rigidity is provided, namely produce bigger vibration isolating effect when vehicle accelerates and shifts gears, improve the comfortableness in vehicle travel process.Y-direction collision block under vehicle stationary state with the intermediate plate on housing, owing to this collision block creates smaller linearity range rigidity value, shown in Y-direction stiffness curve figure, Y linearity range positively and negatively is 2mm, more than namely producing relatively larger rigidity value after the displacement of 2mm, when vehicle steering wheel rotation in the process of moving, power assembly is made to be limited in smaller scope, will not produce to rock in enging cabin, give safe driving sense.
