The specific embodiment
The invention discloses a kind of profile and connect stabilizer rod, substitute original welding process, avoid welding the harmful effect that brings, and then guarantee the quality of stabilizer rod.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
See also Fig. 2, the profile that Fig. 2 provides for the embodiment of the invention connects the local structure for amplifying scheme drawing of stabilizer rod.
The profile that the embodiment of the invention provides connects stabilizer rod; Comprise interconnective hollow torsion bar 11 and swing arm bar 12; Core inventive point of the present invention is; The end of hollow torsion bar 11 is a profile axle 111, and swing arm bar 12 has the profile hole 121 of matching with profile axle 111 with hollow torsion bar 11 bonded assembly ends, and hollow torsion bar 11 and swing arm bar 12 link together through profile.
Compare with existing design, the profile that the embodiment of the invention provides connects stabilizer rod, and its maximum improvement is; The end of hollow torsion bar 11 is a profile axle 111; Swing arm bar 12 has the profile hole 121 of matching with profile axle 111 with hollow torsion bar 11 bonded assembly ends, through profile axle 111 and profile hole 121 hollow torsion bar 11 is linked together with swing arm bar 12, has substituted original welding process; The harmful effect of having avoided welding to bring has guaranteed the stabilizer rod quality.
It is that the profile axle 111 that machinework forms cooperates to come transfer torque with profile hole 121 that this profile connects, and mach advantage to be assembly quality guarantee easily, and then avoided the buckling deformation of stabilizer rod.
The profile axle 111 of hollow torsion bar 11 is an interference fit with the profile hole 121 of swing arm bar 12.So, at normal temperatures, hollow torsion bar 11 is more firm with being connected of swing arm bar 12, has avoided the spacious inefficacy of joint face pine of stabilizer rod.When needs stable installation bar, only need it be swollen to profile hole 121 heating of swing arm bar 12 so that with profile axle 111 assemblings of hollow torsion bar 11.
The profile axle 111 of hollow torsion bar 11 ends can have various ways, and its cross sectional shape also can be ellipse or polygon or the like.Profile axle 111 cross sectional shapes of hollow in the present embodiment torsion bar 11 are polygon, and the profile hole 121 of swing arm bar 12 is the polygon that cooperates with it.
Polygon comprises square, pentagon, hexagon or the like, both can be regular, also can be fitfull.Profile axle 111 cross sectional shapes of hollow here torsion bar 11 are specially the mellow and full excessive equilateral triangle in corner; Profile hole 121 cross sectional shapes of swing arm bar 12 are the mellow and full excessive equilateral triangle in corner that cooperates with it; Its leg-of-mutton limit can be camber line shape, and the camber line shape of corner has protected swing arm bar 12 and hollow torsion bar 11 when transfer torque, should not wear and tear.Through adopting such shape to cooperate, stabilizer rod has reasonable stability, has both made things convenient for assembling, has guaranteed being rigidly connected of swing arm bar 12 and hollow torsion bar 11 again, thus the failure-free transfer torque.
In order further to guarantee the reliability of stabilizer rod transfer torque, the profile that the embodiment of the invention provides connects stabilizer rod, and the width of the profile axle 111 of hollow torsion bar 11 is not less than the width in the profile hole 121 of swing arm bar 12.
Profile that the embodiment of the invention provides connects the termination that stabilizer rod also further comprises the end hole that is used to compress into hollow torsion bar 11, and plug 13 shapes match with the hole of hollow torsion bar 11 ends.The profile that the plug 13 of compressing into hollow torsion bar 11 end hole has further been reinforced hollow torsion bar 11 and swing arm bar 12 is connected, and has also kept hollow torsion bar 11 in-to-ins cleaning, has avoided external environment that hollow torsion bar 11 in-to-ins are corroded.
Similarly, plug 13 is an interference fit with the hole of hollow torsion bar 11 ends, and the profile of having reinforced hollow torsion bar 11 and swing arm bar 12 better is connected.When needs are installed plug 13, to the termination cooling it is dwindled, so that assemble with hollow torsion bar 11 end-face holes.
In order to protect swing arm bar and link thereof, also comprise rubber bush 14, rubber bush 14 be set in swing arm bar 12 away from the hole of hollow torsion bar 11 bonded assemblys one end in.Connect swing arm bar and corresponding connection parts part, weakened vibrations between the two, and conveniently replaced, avoided the wearing and tearing of part, prolonged practical life.
Each embodiment adopts the mode of going forward one by one to describe in this specification sheets, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
