Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
As shown in Figure 1 to Figure 3, a kind of noise reduction mounting bracket of vacuum servo pump assembly, including rack body, rack body
Including the crossbearer 1 and vertical frame 2 being connected, frame 2 is indulged equipped with the flexible bradyseism structure to noise reduction, crossbearer 1 is reserved with installation vacuum
The mounting structure of boost pump 9.Vacuum booster pump is installed on crossbearer by mounting structure, by the way that flexible bradyseism structure, drop is arranged
The vibration of low vacuum boost pump and electromagnetic noise.Flexible bradyseism structure uses rubber bradyseism set.
Vertical frame 2 is class L-type structure, and three ends that the two right angles side intersected in class L-type structure is formed are equipped with soft
Property bradyseism structure.As shown in Figure 1, three end flexibility bradyseism structures are respectively that the first rubber bradyseism covers the 3, second rubber bradyseism set
4 and third rubber bradyseism set 5, the line between this three rubber bradyseism set forms triangle, is arranged to such arragement construction, rises
To the good effect for reducing vibration and noise, the key Design structure for reducing first stage vibration noise is formed, while can also
Overall stability after increasing assembly connection.Groove structure is formed in the inside bevel edge of class L-type structure.Groove type structure is close to
The side bending part of one rubber bradyseism set 3 and the second rubber bradyseism set 4 is obtuse angle bending, and female groove structures are close to third rubber
The side bending part of bradyseism set is right-angle bending, such bending structure setting, after vertical frame is fastenedly connected with front longitudinal beam, Neng Gouyou
Effect is avoided inducing direction required for stringer, while having no effect to the front end deformed region of front longitudinal beam.
Above-mentioned mounting structure includes pre-installing mouth and the installation point 6 positioned at pre-installation mouth two sides.In order to guarantee structure setting
Stability, pre-installation mouth is located at the middle part of crossbearer 1, and it is semicircle for pre-installing mouth.When installation, vacuum booster pump is nested into half
In circular pre-installation mouth, vacuum booster pump is fastenedly connected by connecting bolt 7 with installation point 6, and connects bolt 7 and installation
Rubber bradyseism set is equipped between point 6.Defining this rubber bradyseism set is the 4th rubber bradyseism set 8.Two the 4th rubber bradyseism cover 8 pairs
Claim the two sides for being distributed in semicircle pre-installation mouth.The installation frame body of 9 housing of vacuum booster pump passes through fastening bolt and installation point
Cooperation is fastenedly connected, since there are the 4th rubber bradyseism sets between fastening bolt and installation point, for reducing vacuum booster pump
Second stage vibration frequency noise.
In order to advanced optimize structure setting, increase the living space distance of occupant, by above-mentioned vertical frame 2 by fastener with
Front longitudinal beam 10 connects.Fastener uses fastening bolt 11, when in order to guarantee the stability of installation connection, and reduce installation fastening
Vibration and noise, three bolt installation points are set, respectively corresponds above three rubber bradyseism set, that is, respectively corresponds the first rubber
Bradyseism covers the 3, second rubber bradyseism set 4 and third rubber bradyseism set 5, and bolt passes through corresponding rubber bradyseism set and front longitudinal beam fastens
Installation connection.
Front longitudinal beam is equipped with the first deformation inductdion slot 12, the second deformation inductdion slot 13 and the third deformation inductdion of parallel setting
Slot 14, and the first deformation inductdion slot 12, the second deformation inductdion slot 13 and third deformation inductdion slot 14 extend along the longitudinal direction of front longitudinal beam
Setting, fastening bolt passes through flexible bradyseism structure and vertical frame is connect with front longitudinal beam.When installation, by the second deformation inductdion slot 13 and
The corresponding position being located between two horizontal fastening bolts of three deformation inductdion slots 14, i.e., vertical frame are installed on the second deformation inductdion slot 13
With the 14 corresponding position in outside of third deformation inductdion slot, when colliding, stress squeezes three installation points and will fail and slide
It is de-, it effectively avoids inducing direction required for stringer, have no effect to the front end deformed region of front longitudinal beam.
When production, above-mentioned mounting bracket is formed by cold stamping.Specifically, being used as vital tissue part in mounting bracket
Own material be SPHC300, high-strength steel, material thickness is 3mm, and moulding process forms for cold stamping.Vacuum servo pump assembly passes through
Two M6 are bolted on rack body, and rack body welds the nut of two M6 to fix vacuum booster pump.Vacuum servo
Pump assembly is fixed on the mounting bracket such as Fig. 2, and the vibration of vacuum booster pump is reduced by two the 4th rubber bradyseism sets in left and right
And electromagnetic noise, form the key Design structure for reducing first stage vibration noise.Pass through three designed in rack body
The half-open circular hole of R7.5mm covers the 3, second rubber bradyseism set 4 and third rubber bradyseism set 5 to fix the first rubber bradyseism, and herein three
A rubber bradyseism set is used to reduce the second stage vibration frequency noise of vacuum booster pump, verified slow by increasing by three rubber
Shake set, can reduce the vacuum booster pump monomer vibration frequency noise of 3dBA, and effective contribution improves vehicle NVH performance.Installation
When, the assembly after rack body and vacuum booster pump assembly is fixed on front stringpiece of vehicle body by three M6 bolts, because of fixation
Position needs to inhale flexible region for front longitudinal beam when colliding and sees Fig. 3, and this region stringer ontology is from specially to design
Three induction slots, the half-open circular hole of three R7.5mm by vacuum booster pump mounting bracket ontology three are installed with point design,
When colliding, stress squeezes three installation points and will fail and slip, and effectively avoids inducing direction required for stringer,
It has no effect to the front end deformed region of front longitudinal beam.
By the setting of above-mentioned mounting support structure, interior noise is effectively reduced, the back occupant that collides is increased
Living space distance.And the integrated of vacuum servo pump assembly installation is formd, the time and later period of vehicle assembly are improved
The convenience of maintenance has saved assembly and customer repair working hour in later period.
The present invention is exemplarily described in conjunction with attached drawing above.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out；Or not
It is improved, above-mentioned conception and technical scheme of the invention are directly applied into other occasions, in protection scope of the present invention
Within.
