Abstract
The utility model discloses a fore-low controlling arm of the automobile, including a L-shape controlling arm stamped out from steel plate, steel pipe welded at the corner of the controlling arm for installing rubber sleeve and bolt welded at the end of the upper arm of the controlling arm. The model is characterized in: plug welding slot bore are in the near end part of the controlling arm; the bolt is welded at the end of the upper arm of the controlling arm and welded to the inner wall of the upper arm through the plug welding slot. The utility model adopts the technical plan mentioned above that plug welding slot is at the end of the upper arm. The bolt is connected to the inner wall of the upper arm through the plug welding slot besides the end of the controlling arm. The welding part is increased so that the stress concentration problem is well solved and the stiffness and strength of the whole controlling arm is enhanced.
Description
Technical field
The utility model relates to the preceding Lower control arm of a kind of automobile.
Background technology
Lower control arm (L type Control arm) is used for the suspension of mcpherson type more before the automobile.Its structure is substantially: be welded with the steel pipe 12 and the bearing pin 13 that forges that are used to install rubber bush on the Control arm body 11 that steel stamping part forms, the The whole control arm is " L " type structure, though this structure can improve the rigidity of Control arm itself, but aspect the weld of steel stamping part and bearing pin, stress concentration appears easily.
Summary of the invention
The utility model is in order to overcome the shortcoming of the stress concentration that Lower control arm exists before the existing automobile, and Lower control arm before a kind of later-model automobile that provides, Lower control arm can solve problem of stress concentration well before this automobile, and improves the rigidity and the intensity of The whole control arm.
The technical scheme that the utility model is taked is: Lower control arm before the automobile comprises: the Control arm body of similar " L " shape that the steel plate punching press forms, be welded on the bearing pin the steel pipe of rubber bush being installed and being welded on Control arm body upper arm ends of being used in Control arm body bight; Be characterized in that described Control arm body upper arm close end is provided with the plug welding slotted eye, described bearing pin is welded on Control arm body upper arm ends and welds by plug welding slotted eye and Control arm body upper arm inwall.
Lower control arm before the above-mentioned automobile, wherein, described Control arm body is welded by the lamellar body of two plate shape symmetries is involutory, and its upper arm ends is a cavity.
Lower control arm before the above-mentioned automobile, wherein, described Control arm body is by two peripheries involutory being welded of lamellar body of flange and shape symmetry in opposite directions, its inner cavity that forms.
Lower control arm before the above-mentioned automobile, wherein, the lamellar body of described two plate shape symmetries is a steel stamping part, its upper arm close end respectively is provided with a plug welding slotted eye.
Lower control arm before the above-mentioned automobile, wherein, described Control arm body is provided with reinforced rib.
Lower control arm before the above-mentioned automobile, wherein, the underarm close end of described Control arm body is provided with connecting bore.
