Description
Technical field
This utility model is related to a kind of mounting screw and nut assembly, and in particular to a kind of installation spiral shell for Rear secondary frame for vehicle
Nail and nut assembly.
Background technology
Subframe can regard the skeleton of tandem axle as, be the ingredient of tandem axle, and subframe is simultaneously incomplete
Vehicle frame, simply supports tandem axle, the support for hanging, and makes vehicle bridge, suspension be connected with " positive vehicle frame " by it again, is traditionally referred to as
" subframe ".The effect of subframe is to intercept vibration and noise, reduces which and is directly entered compartment, so occurring in mostly luxurious car
On offroad vehicle, some automobiles also load onto subframe for engine.Conventional without the monocoque body of subframe, its suspension is direct
It is connected with vehicle body steel plate.Therefore the suspension rocker arm body of tandem axle is all loose mail, not assembly.Subframe be born with
Afterwards, front and rear suspension first can be assembled on subframe, constitute an axle assembly, this assembly is together installed to car again then
With, certainly, this suspension assembly with subframe, except in design, installing and can bring beyond various convenience and superiority,
The most important or raising of its comfortableness and suspension stiffness, automobile engine simultaneously non-immediate are rigidly connected with vehicle body.But it is logical
Cross suspension to be connected with vehicle body.Suspension is exactly that our Jing can often see, the rubber mount of electromotor and vehicle body junction.With skill
The development of art, the species of suspension are also more and more, and hydraulic mount is adopted luxury car more.The effect of suspension is for completely cutting off electromotor
Vibrations.That is, in the presence of suspension, engine vibration as few as possible can be transferred to driving cabin.As electromotor exists
Every speed range section has different vibrant characteristics, so good suspending mechanism can effectively shield every speed range section
Vibrations.Here it is why we when opening some and matching preferable luxury cars, no matter electromotor is in 2000 turns
5000 turns, when driving the reason for all imperceptible too many engine vibrations, the junction point of subframe and vehicle body is just as starting
Machine suspension is the same.A usual axle assembly needs to be connected with vehicle body by four suspension points, so both can guarantee that its coupling stiffness,
There can be vibrations isolation effect well again.
It is very big due to shaking in subframe internal medium, it is therefore desirable to provide that a kind of coupling stiffness is good, anti seismic efficiency is strong
Installation bolt and nut assembly.
Utility model content
Technical problem to be solved in the utility model be for above-mentioned the deficiencies in the prior art,
A kind of good rigidity, anti seismic efficiency strong mounting screw and nut assembly for Rear secondary frame for vehicle are provided.
For achieving the above object, this utility model provides following technical scheme：A kind of installation spiral shell for Rear secondary frame for vehicle
Nail and nut assembly, including mounting screw and nut, it is characterised in that：The mounting screw main body is cylindric, the installation
Screw upper end is nut connecting portion, and the external screw thread for attaching nut, the mounting screw are provided with the nut connecting portion
It is connected with nut by the external screw thread arranged on nut connecting portion, the female thread equal length of the external thread length and nut,
Trim ring, the trim ring ovalize are provided with the middle part of the screw, its one end is provided with circular buffer part, the trim ring and screw one
Molding, the screw lower end are provided with Rear secondary frame for vehicle connecting portion, and the Rear secondary frame for vehicle connecting portion is provided with for connecting Rear secondary frame for vehicle
External screw thread.
A kind of above-mentioned mounting screw and nut assembly for Rear secondary frame for vehicle can be further arranged to：The nut includes
There is hexagonal body, the hexagonal body is provided with the projection of molding in conjunction, and the projection is rounded, the hexagon master
Every a line of body is intersected with projection.
A kind of above-mentioned mounting screw and nut assembly for Rear secondary frame for vehicle can be further arranged to：The mounting screw
And nut is 35GrMo materials.
A kind of above-mentioned mounting screw and nut assembly for Rear secondary frame for vehicle can be further arranged to：The mounting screw
And nut outer surfaces are coated with zinc coat.
The beneficial effects of the utility model are：Nut is installed and screw assembly anti seismic efficiency is good, ruggedness is strong.
With reference to the accompanying drawings and examples this utility model is described in further detail.
