Abstract
The invention discloses a kind of structure of front auxiliary frame, a rigid damping crossbeam is provided with front of its fore sub frame body, two control arms are connected by rear portion of the back bush directly with fore sub frame body both sides, it is connected by front lining with damping the both ends of crossbeam, damps the rear of crossbeam both ends, be connected with fore sub frame leading section.The structure of front auxiliary frame, after vibration is delivered to control arm caused by the friction on tire and ground, the reversal of vibrations of both sides control arm can absorb counteracting because damping crossbeam, so as to efficiently reduce the vibration and the noise that are delivered to front frame and driver's cabin, lift the comfortableness of automobile.
Description
Technical field
The present invention relates to a kind of automobile chassis structures, particularly a kind of structure of front auxiliary frame.
Background technology
The important component that it is vehicular chassis system that fore sub frame, which is, it is the skeleton for connecting tandem axle, except for supporting
Outside the multiple parts for connecting automobile, additionally it is possible to barrier vibration and noise, reduce it and be directly entered compartment, it is comfortable to improve automobile
Property.
Existing structure of front auxiliary frame, as shown in figure 1, the both sides of fore sub frame 4 are respectively provided with a control arm 1, control arm 1
Front lining 2 and back bush 3 are provided with, front lining 2 and back bush 3 connect fore sub frame 4.Caused vibrating noise in traveling, according to
It is secondary through left and right tire, control arm, front lining, fore sub frame, then conduct to vehicle body.In order to avoid fore sub frame is to automobile load band
The influence come, fore sub frame design can reduce its deadweight, the anteriomedial indent of usual fore sub frame as far as possible, and both sides evagination is formed
Protuberance, the front lining of control arm are connected on the protuberance of both sides.By bushing transmission come vibration, reach protuberance after,
Vehicle body is delivered to via subframe, because two protuberances are independent of one another, therefore the vibration of its both sides is delivered to protuberance, not Tongfang
To vibration can not also absorb counteracting, it, which drops, shakes that to subtract dry effect not ideal enough.
The content of the invention
The present invention is providing a kind of more preferable structure of front auxiliary frame of reducing vibration and noise effect, further to improve automotive interior sky
Between particularly driver's cabin comfortableness.
The invention discloses a kind of structure of front auxiliary frame, including fore sub frame body, fore sub frame or so is separately positioned on
Two control arms of both sides, two control arms are equipped with front lining and back bush, and a rigidity is provided with front of fore sub frame body
Damping crossbeam, two control arms are connected by rear portion of the back bush directly with fore sub frame body both sides, pass through front lining and resistance
The both ends connection of Buddhist nun's crossbeam, damps the rear of crossbeam both ends, is connected with fore sub frame leading section.
The structure of front auxiliary frame of automobile of the present invention, its fore sub frame body longitudinal separation shorten, before control arm
The front lining at end is no longer connected with fore sub frame body, but is connected on the rigid damping crossbeam in front of fore sub frame, is led to
Cross rigid damping crossbeam directly to connect the front lining of the control arm of both sides, the vibration that both sides control arm transmission comes directly is transmitted
Onto damping crossbeam, the vibration of left and right sides opposite direction can directly absorb counteracting, effectively reduce conduction to fore sub frame
Vibration, it is delivered to the vibration of vehicle body driver's cabin and by vibrating formed noise so as to reduce, improves the comfortable of interior space
Property, passenger, driver is obtained more preferable car experience.Simultaneously as secondary car before being shortened while its increase damping crossbeam
The longitudinal separation of frame body, so even adding damping beam part, the overall weight of fore sub frame will not also increase, and incite somebody to action
When damping crossbeam is arranged to the middle part concave inward structure of rear side, the overall weight of fore sub frame has even mitigated on the contrary, makes structure
More light, oil consumption is lower.
Brief description of the drawings
Fig. 1 is the structure of front auxiliary frame schematic diagram of traditional design.
Fig. 2 is the schematic diagram for the structure of front auxiliary frame that the present invention provides.
Fig. 3 is the junction partial sectional view of control arm and damping crossbeam.
Embodiment
As shown in Fig. 2 a kind of structure of front auxiliary frame of automobile, the front end retraction of its fore sub frame body 4, make longitudinal separation
Shorten, the front lining 2 of control arm is then integrally located at the front of fore sub frame body 4.It is provided with the front end of fore sub frame body 4
One it is rigid damping crossbeam 5, damp crossbeam 5 left and right ends bottom be then connected in fore sub frame by way of welding before
In the left and right ends portion of side.Both sides are rigidly connected by damping crossbeam, and both sides control arm is delivered to the horizontal vibration of beam of damping, phase
Opposite direction can mutually absorb counteracting, so as to be reduced to the vibration for being delivered to vehicle body, lift comfortableness.
Damping crossbeam is preferred by flute profile of section, and it can make damping crossbeam have preferable strength and stiffness, so as to more
The absorption for being advantageous to vibration is offset.
Damping crossbeam is preferred with the concordant then middle side part indent in front side, the damping crossbeam of indent and fore sub frame main body it
Between form vacancy, with ensure both sides absorption of vibrations offset while, further mitigate whole fore sub frame weight, so as to reduce
The harmful effect that deadweight is brought.The longitudinal separation for the fore sub frame body that the damping beam structure of indent sets and shortened,
So that the fore sub frame overall structure of the present invention, even if in the case where adding damping beam part, its overall weight also can
Do not increase, or even mitigated on the contrary, make structure more light, oil consumption is lower.
It can also be connected between damping crossbeam and fore sub frame body by bolt, such as Fig. 3, damp crossbeam and preceding secondary car
Frame body junction sets friction plate 6 made of friction material, and the coefficient of friction of friction plate is very high, so as to hinder preceding pair
Relative motion between frame body and damping crossbeam.
