Abstract
The utility model relates to an automotive front suspension system lower control arm comprising a body, a shaft rod, a front bushing and a rear bushing. The body is made of aluminum and the shaft rod is made of steel. The front bushing is pressed into a cylindrical shell of the body via a bushing outer tube in an interference manner. The shaft rod is fixedly connected with the body through a flange on one end thereof and the other end is fixedly connected with the rear bushing. The body and the shaft rod of the front lower control arm are separated to be two independent parts and the body is still an aluminum body so that the advantage of lightness can be maintained while the requirements for strength and durability are met; the shaft rod is made of steel and has higher strength compared with a shaft rod made of aluminum, so that the reliability of the shaft rod can be guaranteed.
Description
Technical field
The utility model relates to a kind of front overhang frame system Lower control arm.
Background technology
Front suspension system Lower control arm belongs to suspension guide mechanism, by lining or ball end, directly or indirectly connects vehicle body and wheel, controls wheel trace, and force and moment is delivered to vehicle body.
The manufacturing process that orthodox car front suspension system Lower control arm agent structure adopts mainly contains four kinds of steel plate stamping weldering, Ductile Iron Casting, forged steel and wrought aluminiums, and in view of larger to reducing unsprung weight contribution degree, high-end vehicle adopts the wrought aluminium structure that cost is relatively high conventionally.
In general, front overhang frame system Lower control arm main body and the axostylus axostyle of traditional wrought aluminium structure are structure as a whole, and by former and later two linings, are connected with vehicle body end, by a ball end, are connected with road wheel end.With vehicle body coupling end, front lining is pressed in interference mode in the cylindrical shell of Control arm main body by lining outer tube conventionally, and back bush is pressed on Control arm axostylus axostyle in interference mode by inner tube conventionally.Due to aluminium intensity a little less than, and two linings are again stressed two the larger positions of suspension system, so the intensity of Control arm is difficult to guarantee conventionally.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of when meeting intensity and durable requirement, can keep its lightweight advantage, and the front overhang frame system Lower control arm of good reliability.
In order to solve the problems of the technologies described above, front overhang frame system Lower control arm of the present utility model comprises main body, axostylus axostyle, front lining and back bush; Described main body is aluminium body, and axostylus axostyle is steel axostylus axostyle; Front lining is pressed in the cylindrical shell of main body by lining outer tube in interference mode; Axostylus axostyle is fixedly connected with main body by the flange of its one end, and the other end tightens up and is connected with back bush.
The other end of described axostylus axostyle tightens up and is connected with back bush in interference mode, or the other end of axostylus axostyle is through back bush inner tube, its end is connected with nut thread back bush inner tube is clamped, realization tightens up connection, or the end machinework negative thread of the other end of axostylus axostyle, coordinate with bolt back bush inner tube is clamped, realize and tighten up connection.
The utility model is split as two independently parts by front Lower control arm main body and axostylus axostyle, and main body is still aluminium body, when meeting intensity and durable requirement, can keep its lightweight advantage; Axostylus axostyle adopts steel manufacture, in contrast to aluminium, carrying the high-intensity while, can guarantee its reliability.

The specific embodiment
As shown in Figure 1, the front overhang frame system Lower control arm main body 1 ' of tradition wrought aluminium structure is structure as a whole with axostylus axostyle 2 ', front lining 5 is pressed in the cylindrical shell 6 of main body 1 ' in interference mode by lining outer tube, and back bush 3 is pressed on axostylus axostyle 2 ' in interference mode by inner tube.
As shown in Fig. 2 to 5, front overhang frame system Lower control arm of the present utility model comprise main body 1,, axostylus axostyle 2, front lining 5, back bush 3.Described main body 1 is aluminium body, and axostylus axostyle 2 is steel axostylus axostyle.Front lining 5 is pressed in the cylindrical shell 6 of main body 1 in interference mode by lining outer tube.One end of axostylus axostyle 2 is with flange 7, the circular via hole of machinework on flange 7; The tapped bore that main body 1 coordinates with circular via hole on flange 7 with the fitting surface machinework of flange 7; Flange 7 is connected and fixed by bolt 8 with main body 1.The other end of axostylus axostyle 2 can adopt interference mode to tighten up and be connected with back bush 3 inner tubes cooperation realizations; The other end of axostylus axostyle 2 also can adopt its end machinework outside thread, back bush 3 inner tubes is clamped by screw thread fit with nut 4, realizes and tightens up connection; The other end of axostylus axostyle 2 can also adopt its end machinework negative thread, coordinates back bush 3 inner tubes are clamped with bolt, realizes and tightens up connection.
