Frame.But the patent does not solve between prior art fore sub frame upper and lower plates that support strength is inadequate, can be produced using bolt fastening
The problem of raw larger noise.
Utility model content
The utility model is that empty support strength is insufficient between the upper and lower plate of existing automobile front subframe in order to overcome, and is generated
The problem of larger vibration noise, provides a kind of fore sub frame of low noise, so that having good branch between the upper and lower plate of fore sub frame
Intensity is supportted, and reduces the vibration noise of subframe generation.
To achieve the goals above, the utility model uses following technical scheme: including upper plate, lower plate and support sleeve
Pipe, characterized in that the lower plate is equipped with outer surface and inner surface, and the lower plate is equipped with identical recessed with the supporting sleeve quantity
Concave portion, the recessed portion are equipped with the installation through-hole to match with the supporting sleeve outer diameter, and the supporting sleeve upper end is welded in
The installation through-hole is stretched out in the upper plate, the lower end, and the supporting sleeve is welded close to bottom side of the wall and the recession plane
It is fixed.
There is cavity structure between the fore sub frame upper and lower plates of automobile.Supporting sleeve in the technical program is to fore sub frame
Upper and lower plates be supported.It is set between upper and lower plates using a number of supporting sleeve, preferably uses four support sleeves
Pipe supports upper and lower plates.The supporting sleeve upper end is welded on the corresponding position of the upper plate first, it then will be described
Installation through-hole at the recession plane of lower plate is directed at the supporting sleeve being welded, then will weld between supporting sleeve lower end and recession plane
Connect fixation.The recessed portion can make welding more aspect, while keep wlding accumulation more uniform, to keep weld seam stronger.
The supporting sleeve lower end is set to stretch out described installation through-hole a distance, it in this way can be by the supporting sleeve under
The side wall at end is welded and fixed with recession plane, increases the contact area of welding, so that welding more aspect is firm.Compare existing skill
The mounting means of tools for bolts ' pretension is used in art, the technical program eliminates the gap between lower plate and supporting sleeve, so as to avoid
Biggish vibration noise is generated between lower plate and supporting sleeve.
Preferably, between the recessed portion and the lower plate outer surface be equipped with transition inclined surface, the inclined surface with it is described
Knuckle is equipped between recessed portion and the lower plate outer surface.The stress that lower plate recess can be reduced in this way is concentrated, and is conducive to
Improve the intensity of fore sub frame.
Preferably, the supporting sleeve lower end surface and the lower plate flush with outer surface.Supporting sleeve lower end surface and lower plate
Outer surface between it is horizontal concordant, such casing extension had both facilitated welding, so that weld seam is more firm, and will not be to preceding pair vehicle
Other spare and accessory parts have the risk for generating and interfering outside frame lower plate.
Preferably, the supporting sleeve lateral wall is equipped with annular locating lug boss, and the positioning convex platform is resisted against described recessed
Concave portion inner surface.In order to improve the assembly efficiency, while making lower plate positioning more accurate, the supporting sleeve is along lateral wall
It is circumferentially with the positioning convex platform of a loop, the installation through-hole of lower plate recessed portion can be directly aligned by such worker in assembly
Supporting sleeve pressure, until being pressed on positioning convex platform.
Preferably, the buffer gasket of elastic material is equipped between the annular locating lug boss and the lower plate inner surface.It is preferred that
The elastic material use rubber.According to the working condition of fore sub frame, generally it is often subjected to vibrate up and down, so it is described
Annular locating lug boss upper surface and lower plate inner surface between might have vibration noise generation, therefore can be set therebetween
Elastic material reduces noise to buffer absorbing.
Preferably, the upper plate is equipped in the identical positioning through hole of the supporting sleeve quantity, the positioning through hole it is straight
The internal diameter of diameter and the supporting sleeve matches.Quickly supporting sleeve can be positioned and be welded in upper plate with more acurrate in this way.
In conclusion the utility model has the following beneficial effects: there is the cavity between the upper and lower plate of fore sub frame
Good support strength, and the gap between lower plate and supporting sleeve is eliminated, keep fixation between the two more firm, thus
It avoids and generates biggish vibration noise between lower plate and supporting sleeve.
