Description
Technical field
The present invention relates to automobile manufacturing field more particularly to a kind of McPherson suspension lower swing arm bushing mounting structures.
Background technique
McPherson suspension is one of widest car front suspension frame of the world today, by helical spring, damper, three
Angular lower swing arm composition, most vehicles can also add stabilizer bar.The simple light weight of MacPherson type suspended structure, under
Under the geometry of swing arm and column support type damper can adjust automatically camber angle, can when excessively curved adaptive road surface.
Lower swing arm is usually the design of A font, bears the parts transversely support force of wheel, and whole front-rear directions
Load, due to McPherson suspension be straight barrel type, automobile resist side knock ability it is weaker, it is anti-brake nod act on it is poor,
Suspension stiffness is weaker, and cornering roll is obvious, this make automobile turn or brake at present bush of swing arm bear biggish load,
If the selection of bushing rigidity is unreasonable, it can make bushing that fracture failure or tired broken occur when bushing is by transverse direction and longitudinal direction shearing force
It is bad；Bottom arm bush is bolted with subframe so that subframe bolt location stress concentrate, as fruit structure design it is bad without
The stress that bolt location can effectively be shared then be easy to cause subframe bolt location metal plate to crack, reduces the fatigue of front suspension
Service life.
Summary of the invention
The object of the present invention is to provide a kind of McPherson suspension lower swing arm bushing mounting structures, increase the intensity of tie point
With rigidity, the stress of bolt location has been shared, has improved the service life of installation point, has reduced the destruction risk of extending stress band.
Technical scheme is as follows:
The reinforcement structure that McPherson suspension bottom arm bush is connect with subframe, including subframe, the installation of subframe front end
There is upward subframe bushing mounting plate, lower swing arm outwardly, feature are installed on subframe bushing mounting plate and subframe
Be: the lower swing arm is A font, and a stabilizer blade and the subframe side wall of lower swing arm are mutually fixed, another stabilizer blade is outer from upper
There is reinforced support to lower fastening, reinforced support includes left riser, the right riser for being symmetrically fixed on connection board ends, left riser, the right side
Five bolts hole point-blank are symmetrically distributed on riser, external fasten of the reinforced support has lower swing arm lining
Set, further includes five clamping screws, one of bolt sequentially pass through bottom arm bush, left riser, lower swing arm another stabilizer blade,
Right riser, subframe bushing mounting plate are mutually fixed with subframe, remaining four screw bolt passes bottom arm bush, left riser,
Lower swing arm another stabilizer blade, right riser are mutually fixed with subframe bushing mounting plate.
The reinforcement structure that the McPherson suspension bottom arm bush is connect with subframe, it is characterised in that: described adds
The connecting plate and left riser, right riser junction arc-shaped transition of strong bracket are equipped with the protrusion muscle towards inside at arc-shaped transition, dash forward
Muscle is hemispherical protuberance out.
The reinforcement structure that the McPherson suspension bottom arm bush is connect with subframe, it is characterised in that: described adds
Strong bracket generally metal plate punching part, 2 ~ 6mm of thickness.
The reinforcement structure that the McPherson suspension bottom arm bush is connect with subframe, it is characterised in that: under described
It is U-shaped structure that bush of swing arm, which is equipped with, and the bottom of bottom arm bush is equipped with corresponding with the multiple bolt hole positions of reinforced support
Fixation hole.
The invention has the advantages that
1. in the present invention, McPherson suspension bottom arm bush reinforced support improves the rigidity and intensity at tie point, greatly
The stress that bushing is bolted position is reduced greatly, improves the service life of bushing installation point；
2. the reinforced support in the present invention is designed by reinforcement and round-corner transition, bracket overall stiffness is improved, is facilitated
Prevent the bending or torsional deflection of bracket；
3. the difference that the reinforced support structure in the present invention can be arranged according to vehicle type structure, changes metal plate thickness and cuts
Face or curve form, while the position of bolt and specification being installed can also depend on the circumstances；
4. the present invention effectively prevents bushing tie point region problem of Cracking, reinforced support round-corner transition and reinforcement knot
Structure, which reduces stress collection and neutralizes, improves the rigidity of reinforced support, avoid reinforced support because caused by insufficient rigidity bracket crack,
For backward, if reinforced support occurs cracking or can play booster action to bushing tie point, subframe will not be reduced
Performance；
It is more obvious to the stress improved at installation point 5. reinforced support structure provided by the present invention is simple, cost compared with
It is low, it is easily achieved in production, and be easily installed and dismantle.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial enlarged view of reinforced support installation position of the invention.
Fig. 3 is reinforced support structural schematic diagram of the invention.
Specific embodiment
Referring to attached drawing:
The reinforcement structure that McPherson suspension bottom arm bush is connect with subframe, including subframe 1,1 front end of subframe peace
Equipped with upward subframe bushing mounting plate 2, lower swing arm 3 outwardly is installed on subframe bushing mounting plate 2 and subframe 1,
Lower swing arm 3 is A font, and a stabilizer blade and 1 side wall of subframe of lower swing arm 3 are mutually fixed, and is fastened from top to bottom outside another stabilizer blade
There is reinforced support 4, reinforced support 4 includes left riser 4-2, the right riser 4-3 for being symmetrically fixed on the both ends connecting plate 4-1, left riser
Five bolt hole 4-4 point-blank are symmetrically distributed on 4-2, right riser 4-3, under the external fastening of reinforced support 4 has
